8.3.3 Output Voltage Monitor and PGOOD Generation

The TPS6593-Q1 device monitors the undervoltage (UV) and overvoltage (OV) conditions on the output voltages of the BUCK and LDO, regulators and VCCA (when it is expected to be 5 V or 3.3 V), and has the option to indicate the result with a PGOOD signal. Thermal warning can also be included in the result of the PGOOD monitor if it is not masked. Either voltage and current monitoring or only voltage monitoring can be selected for PGOOD indication. This selection is set by the PGOOD_SEL_BUCKn register bits for each BUCK regulator (select primary phase for multi-phase regulator), and is set by the PGOOD_SEL_LDOn register bits for each LDO regulator. When voltage and current are monitored, an active PGOOD signal active indicates that the regulator output is inside the Power-Good voltage window and that load current is below the current limit. If only voltage is monitored, then the current monitoring is ignored for the PGOOD signal.

The PGOOD signal represents the momentary status of the included indications without latching. If the PGOOD signal goes low due to an indicated warning or error condition, the PGOOD signal goes high immediately when the previous indicated warning or error condition is no longer present.

The BUCKn_VMON_EN bit enables the overvoltage (OV) , undervoltage (UV) and short-circuit (SC) comparators. The current limit (ILIM) comparator of each BUCK regulator is activated as soon as the corresponding BUCK regulator is enabled. In order to add the current limit indication of a BUCK regulator to the PGOOD signal, the BUCKn_VMON_EN bit of the corresponding BUCK regulator must be set. For LDO regulators, the LDOn_VMON_EN bit enables the OV and UV, short-circuit (SC) comparators. The current limit (ILIM) comparator of each LDO regulator is activated as soon as the corresponding LDO regulator is enabled. In order to add the current limit indication of an LDO to the PGOOD signal, the LDOn_VMON_EN bit of the corresponding LDO regulator must be set. When a BUCK or an LDO is not needed as a regulated output, it can be used as a voltage monitor for an external rail. For BUCK converters, if the BUCKn_VMON_EN bit remains '1' while the BUCKn_EN bit is '0', it can be used as a voltage monitor for an external rail that is connected to the FB_Bn pin of the BUCK regulator. For LDO regulators, if the LDOn_VMON_EN bit remains '1' while the LDOn_EN bit is '0', it can be used as a voltage monitor for an external rail which is connected to the VOUT_LDOn pin.

When the voltage monitor for a BUCK or LDO regulator is inactive, the output of the corresponding monitor is automatically masked to prevent it from forcing PGOOD inactive. The masking allows PGOOD to be connected to other open-drain power good signals in the system.

The VCCA input voltage monitoring is enabled with VCCA_VMON_EN bit. The monitoring can be enabled by an NVM default setting, that starts the monitoring of the VCCA voltage after the device passes the BOOT BIST state. The reference voltage for the VCCA monitor can be set by the VCCA_PG_SET bit to either 3.3 V or 5 V. The PGOOD_SEL_VCCA register bit selects whether or not the result of the VCCA monitor is included in the PGOOD monitor output signal.

An NVM option is available to gate the PGOOD output with the nRSTOUT and the nRSTOUT_SoC signals, the intended reset signals for the safety MCU and the SoC respectively. When PGOOD_SEL_NRSTOUT = '1', the PGOOD pin is gated by the nRSTOUT signal. When PGOOD_SEL_NRSTOUT_SOC = '1', the PGOOD pin is gated by the nRSTOUT_SoC signal. This option allows the PGOOD output to be used as an enable signal for external peripherals.

The outputs of the voltage monitors from all the output rails are combined, and PGOOD is active only if all the sources shows active status.

The type of output voltage monitoring for PGOOD signal is selected by PGOOD_WINDOW bit. If the bit is 0, only undervoltage is monitored; if the bit is 1, then undervoltage and overvoltage are monitored.

The polarity and the output type (push-pull or open-drain) are selected by PGOOD_POL and GPIO9_OD bits.

Figure 8-10 shows the Power-Good generation block diagram, and Figure 8-11 shows the Power-Good waveforms.

Figure 8-11 PGOOD Waveforms

The OV and UV threshold of the voltage monitors of the BUCK regulators and the LDO regulators are updated automatically by the digital control block when the output voltage setting changes. When the output voltage of the regulator is increased, the OV threshold is updated at the same time the _VSET of the regulator is changed. The UV threshold is updated after a delay calculated by the delta voltage change and the slew rate setting. When the output voltage is decreased, the UV threshold is updated at the same time the _VSET of the regulator is changed. The OV threshold is updated after a delay calculated by the delta voltage change and the slew rate setting. The OV and UV threshold of the BUCK and LDO output voltage monitors are calculated based on the target output voltage set by the corresponding BUCKn_VSET1, BUCKn_VSET2, or LDOn_VSET registers, and the deviation from the target output voltage set (the voltage window) by the corresponding BUCKn_UV_THR, BUCKn_OV_THR, LDOn_UV_THR, and the LDOn_OV_THR registers. For the OV and UV threshold of BUCK and LDO output monitors to update with the correct timing, the following operating procedures must be followed when updating the _VSET values of the regulators to avoid detection of OV/UV fault:

  • BUCK and LDO regulators must be enabled at the same time as or earlier than as their VMON
  • New voltage level must not be set before the start-up has finished
  • New voltage level must not be set before the previous voltage change (ramp plus settling time) has completed

The voltage monitors of unused BUCK or LDO regulators can be used for external supply rails monitoring. In three-phase configuration, the Voltage Monitor of BUCK3 (on FB_B3 pin) becomes a free available resource for monitoring an external supply voltage. In four-phase configuration, the Voltage Monitor of both BUCK3 (on FB_B3 pin) and BUCK4 (on FB_B4 pin) become free available resources for monitoring two external supply voltages.. The target output voltage is set by the corresponding BUCKn_VSET1, BUCKn_VSET2, or LDOn_VSET registers, and the deviation from the target output voltage set (the voltage window) by the corresponding BUCKn_UV_THR, BUCKn_OV_THR, LDOn_UV_THR, and the LDOn_OV_THR registers. Following aspects need to be taken into account if Voltage Monitors of unused BUCK or LDO regulators are used for monitoring external supply rails:

  • For voltage monitors of unused LDO regulators: the voltage level applied at the VOUT_LDOx pin, inclusive expected tolerances, must be below the supply voltage applied at the PVIN_LDOx pin
  • For voltage monitors of unused BUCK and LDO regulators: the maximum nominal supply voltage of the monitored supply rail is 3.3V
  • For voltage monitors of unused BUCK regulators and for voltage monitors of BUCK3 and/or BUCK4 regulators if used in a three-phase or four-phase configuration: the configured values for the BUCKn_VSET and the BUCKn_SLEW_RATE determine the delay-time for the voltage monitoring to become active after the corresponding BUCKn_VMON_EN bit is set.

のクロック信号に同期させることができます。EMC 性能を向上させるため、同期した BUCK のスイッチング・クロック信号にスペクトラム拡散変調を加える機能を内蔵しています。このクロック信号は、GPIO 出力ピンを介して外部のデバイスで利用することもできます。本デバイスは 4 つの LDO を備えています。3 つは 500mA の電流能力を持ち、負荷スイッチとして構成できます。1 つは 300mA の電流能力を持ち、低ノイズ性能が優れています。 不揮発性メモリ (NVM) は、デフォルトの電力シーケンスと設定 (出力電圧、GPIO の設定など) を制御するために使います。NVM は、外部からプログラムしなくても起動できるように事前にプログラムされています。本デバイスのレジスタ・マップに保存されたほとんどの静的設定は、多種多様なシステムの要求を満たすように本デバイスを構成するために、SPI

This reduction of the maximum output voltage protects the processor from exceeding the maximum ratings of the core voltage. The default value is defined in the nonvolatile memory (NVM) and can be updated by software through I2C/SPI interface after device start-up. Additional cooling strategies may be necessary to keep junction temperature at recommended limits. The input buffer of a fail-safe GPIO pin is isolated from its input signal.  Therefore, the input voltage to a fail-safe pin can be as high as 5.5 V.

When DC voltage is applied to a ceramic capacitor, the effective capacitance is reduced due to DC bias effect. The table above therefore lists the minimum value as CAPACITANCE. In order to meet the minimum capacitance requirement, the nominal value of the capacitor may have to be scaled accordingly to take the drop of capacitance into account for a given DC voltage at the outputs of regulators. The maximum output current can be limited by the forward current limit. The maximum output current is also limited by the junction temperature and maximum average current over lifetime. The power dissipation inside the die increases the junction temperature and limits the maximum current depending on the length of the current pulse, efficiency, board and ambient temperature. Additional cooling strategies may be necessary to keep the device junction temperature at recommended limits with large output current. SLEW_RATEx[2:0] register default comes from NVM memory, and can be re-configured by the MCU.  Output capacitance, forward and negative current limits and load current may limit the maximum and minimum slew rates. The final PFM-to-PWM and PWM-to-PFM switchover current varies slightly and is dependent on the output voltage, input voltage, and the inductor current level. The BUCK Regulator does not switch over from PWM to PFM for Fsw=2.2MHz and VOUT < 0.5V Please refer to the applications section of the data sheet regarding the power delivery network (PDN) used for the transient load step and output ripple test conditions.  All ripple specs are defined across POL capacitor in the described PDN. The 33.3 mV/µs slew-rate setting is not recommended for LBx ≥ 1 µH, as this can trigger OV detection due to larger overshoot at the buck output.

voltage of BUCK1 to BUCK5 and LDO1 to LDO4 can be reduced by an NVM setting to adopt the maximum voltage to the requirements (or maximum ratings) of the load. This reduction of the maximum output voltage protects the processor from exceeding the maximum ratings of the core voltage.

When DC voltage is applied to a ceramic capacitor, the effective capacitance is reduced due to DC bias effect. The table above therefore lists the minimum value as CAPACITANCE. In order to meet the minimum capacitance requirement, the nominal value of the capacitor may have to be scaled accordingly to take the drop of capacitance into account for a given dc voltage at the outputs of regulators. Ceramic capacitors recommended Load transient voltage must be considered when selecting UV/OV threshold levels for the LDO output Additional capacitance, including local and POL, beyond the specified value can cause the LDO to become unstable Over operating free-air temperature range (unless otherwise noted).  Voltage level is in reference to the thermal/ground pad of the device.

When DC voltage is applied to a ceramic capacitor, the effective capacitance is reduced due to DC bias effect. The table above therefore lists the minimum value as CAPACITANCE. In order to meet the minimum capacitance requirement, the nominal value of the capacitor may have to be scaled accordingly to take the drop of capacitance into account for a given DC voltage at the outputs of regulators. The maximum output current can be limited by the forward current limit. The maximum output current is also limited by the junction temperature and maximum average current over lifetime. The power dissipation inside the die increases the junction temperature and limits the maximum current depending on the length of the current pulse, efficiency, board and ambient temperature. Additional cooling strategies may be necessary to keep the device junction temperature at recommended limits with large output current. SLEW_RATEx[2:0] register default comes from NVM memory, and can be re-configured by the MCU.  Output capacitance, forward and negative current limits and load current may limit the maximum and minimum slew rates. The final PFM-to-PWM and PWM-to-PFM switchover current varies slightly and is dependent on the output voltage, input voltage, and the inductor current level. The BUCK Regulator does not switch over from PWM to PFM for Fsw=2.2MHz and VOUT < 0.5V Please refer to the applications section of the data sheet regarding the power delivery network (PDN) used for the transient load step and output ripple test conditions.  All ripple specs are defined across POL capacitor in the described PDN. The 33.3 mV/µs slew-rate setting is not recommended for LBx ≥ 1 µH, as this can trigger OV detection due to larger overshoot at the buck output.

When DC voltage is applied to a ceramic capacitor, the effective capacitance is reduced due to DC bias effect. The table above therefore lists the minimum value as CAPACITANCE. In order to meet the minimum capacitance requirement, the nominal value of the capacitor may have to be scaled accordingly to take the drop of capacitance into account for a given DC voltage at the outputs of regulators. The maximum output current can be limited by the forward current limit. The maximum output current is also limited by the junction temperature and maximum average current over lifetime. The power dissipation inside the die increases the junction temperature and limits the maximum current depending on the length of the current pulse, efficiency, board and ambient temperature. Additional cooling strategies may be necessary to keep the device junction temperature at recommended limits with large output current. SLEW_RATEx[2:0] register default comes from NVM memory, and can be re-configured by the MCU.  Output capacitance, forward and negative current limits and load current may limit the maximum and minimum slew rates. The final PFM-to-PWM and PWM-to-PFM switchover current varies slightly and is dependent on the output voltage, input voltage, and the inductor current level. The BUCK Regulator does not switch over from PWM to PFM for Fsw=2.2MHz and VOUT < 0.5V Please refer to the applications section of the data sheet regarding the power delivery network (PDN) used for the transient load step and output ripple test conditions.  All ripple specs are defined across POL capacitor in the described PDN. The 33.3 mV/µs slew-rate setting is not recommended for LBx ≥ 1 µH, as this can trigger OV detection due to larger overshoot at the buck output. Over operating free-air temperature range (unless otherwise noted).  Voltage level are referenced to the thermal/ground pad of the device except for VOUT_Bn in multiphase configurations, in which case, the voltage level is referenced to the negative FB_Bn pin of the differential pair.

When DC voltage is applied to a ceramic capacitor, the effective capacitance is reduced due to DC bias effect. The table above therefore lists the minimum value as CAPACITANCE. In order to meet the minimum capacitance requirement, the nominal value of the capacitor may have to be scaled accordingly to take the drop of capacitance into account for a given DC voltage at the outputs of regulators. The maximum output current can be limited by the forward current limit. The maximum output current is also limited by the junction temperature and maximum average current over lifetime. The power dissipation inside the die increases the junction temperature and limits the maximum current depending on the length of the current pulse, efficiency, board and ambient temperature. Additional cooling strategies may be necessary to keep the device junction temperature at recommended limits with large output current. SLEW_RATEx[2:0] register default comes from NVM memory, and can be re-configured by the MCU.  Output capacitance, forward and negative current limits and load current may limit the maximum and minimum slew rates. The final PFM-to-PWM and PWM-to-PFM switchover current varies slightly and is dependent on the output voltage, input voltage, and the inductor current level. The BUCK Regulator does not switch over from PWM to PFM for Fsw=2.2MHz and VOUT < 0.5V Please refer to the applications section of the data sheet regarding the power delivery network (PDN) used for the transient load step and output ripple test conditions.  All ripple specs are defined across POL capacitor in the described PDN. The 33.3 mV/µs slew-rate setting is not recommended for LBx ≥ 1 µH, as this can trigger OV detection due to larger overshoot at the buck output.

package. The TPS6593-Q1 is designed for powering embedded systems or System on Chip (SoC) in automotive or industrial applications. The TPS6593-Q1 provides five configurable BUCK regulators, of which four rails have the ability to combine outputs in multi-phase mode. BUCK4 has the ability to supply up to 4 A output current in single-phase mode, while BUCK1, BUCK2, and BUCK3 have the ability to supply up to 3.5 A output current in single-phase mode. When working in multi-phase mode, each BUCK1, BUCK2, BUCK3, and BUCK4 can supply up to 3.5 A output current per phase, adding up to 14 A output current in four-phase configuration. BUCK5 is a single-phase only BUCK regulator, which supports up to 2 A output current. All five of the BUCK regulators have the capability to sink a current up to 1 A, and support dynamic voltage scaling. Double-buffered voltage scaling registers enable each BUCK regulator to transition to a different voltage during operation by SPI or I2C. A digital PLL enables the BUCK regulators to synchronize to an external clock input, with phase delays between the output rails. The TPS6593-Q1 device also provides three LDO rails, which can supply up to 500 mA output current per rail and can be configured in bypass mode and used as a load switch. One additional low-noise LDO rail can supply up to 300 mA output current. The 500-mA LDOs support 0.6 V to 3.3 V output voltage with 50-mV step. The 300-mA low-noise LDO supports 1.2 V to 3.3 V output voltage with 25-mV step. The output voltages of the LDOs can be pre-configured through the SPI or I2C interfaces, which are used to configure the power rails and the power states of the TPS6593-Q1 device. I2C channel 1 (I2C1) is the main channel with access to the registers, which control the configurable power sequencer, the states and the outputs of power rails, the device operating states, the RTC registers and the Error Signal Monitors. I2C channel 2 (I2C2), which is available through the GPIO1 and GPIO2 pins, is dedicated for accessing the Q&A Watchdog communication registers. If GPIO1 and GPIO2 are not configured as I2C2 pins, I2C1 can access all of the registers, including the Q&A Watchdog registers. Alternatively, depending on the NVM-configuration of the orderable part number, SPI is the selected interface for the device and can be used to access all registers. The TPS6593-Q1 device includes an internal RC-oscillator to sequence all resources during power up and power down. Two internal LDOs (LDOVINT and LDOVRTC) generate the supply for the entire digital circuitry of the device as soon as the external input supply is available through the VCCA input. A backup battery supply input can also be used to power the RTC block and a 32-kHz Crystal Oscillator clock generator in the event of main supply power loss. TPS6593-Q1 device has eleven GPIO pins each with multiple functions and configurable features. All of the GPIO pins, when configured as general-purpose output pins, can be included in the power-up and power-down sequence and used as enable signals for external resources. In addition, each GPIO can be configured as a wake-up input or a sleep-mode trigger. The default configuration of the GPIO pins comes from the non-volatile memory (NVM), and can be re-programmed by system software if the external connection permits. The TPS6593-Q1 device includes a watchdog with selectable trigger or Q&A modes to monitor MCU software lockup, and two error signal monitor (ESM) inputs with fault injection options to monitor the lock-step signal of the attached SoC or MCU. TPS6593-Q1 includes protection and diagnostic mechanisms such as voltage monitoring on the input supply, voltage monitoring on all BUCK and LDO regulator outputs, CRC on configuration registers, CRC on non-volatile memory, CRC on communication interfaces, current-limit and short-circuit protection on all output rails, thermal pre-warning, and over-temperature shutdown. The device also includes a Q&A or trigger mode watchdog to monitor for MCU software lockup, and two Error Signal Monitor inputs with selectable level mode or PWM mode, and with fault injection options to monitor the error signals from the attached SoC or MCU. The TPS6593-Q1 can notify the processor of these events through the interrupt handler, allowing the MCU to take action in response. An SPMI interface is included in the TPS6593-Q1 device to distribute power state information to at most five satellite PMICs on the same network, thus enabling synchronous power state transition across multiple PMICs in the application system. This feature allows the consolidation of IO control signals from up to six PMICs powering the system into one primary TPS6593-Q1 PMIC. Functional Block Diagram Feature Description System Supply Voltage Monitor The comparator module in TPS6593-Q1, which monitors the voltage on the VCCA pins, controls the power state machine of the device. VCCA voltage detection outputs determine the power states of the device as follows: VCCA_UVLO The TPS6593-Q1 returns to the BACKUP state. LDOVRTC is powered by the output of the Backup Supply Management (BSM) module during the BACKUP state. The device returns to the NO SUPPLY state and is completely shut down when the input supply of the LDOVRTC falls below the operating range. The device cannot return to the BACKUP state from the NO SUPPLY state. VCCA_UV The TPS6593-Q1 transitions from the NO SUPPLY state to the INIT state when the voltage on the VCCA pin rises above VCCA_UV during initial power-up. VCCA_OVP If the voltage on VCCA pin rises above the VCCA_OVP threshold while TPS6593-Q1 is in operation, then the device clears the ENABLE_DRV bit and starts the immediate shutdown sequence. A separate voltage comparator monitors whether or not the VCCA voltage is within the expected PGOOD range when VCCA is expected to be 5-V or 3.3-V. This voltage comparator checks at device power-up whether the voltage on the VCCA supply pin is above the VCCA_UV threshold. Refer to for additional detail on the operation of the PGOOD monitor function. LDOVINT, which is the internal supply to the digital core of the device, may attempt to restart the device when the input voltage at VCCA pin falls or stays between VCCA_UVLO and VCCA_UV voltage levels; the voltage at the VCCA pin, however, must be above the VCCA_UV voltage level for the device to power up properly. shows a block diagram of the VCCA input voltage monitoring. VCCA Monitor Power Resources (Bucks and LDOs) The power resources provided by the TPS6593-Q1 device includes synchronous, current mode control bucks and linear LDOs. These supply resources provide power to the external processors, components, and modules inside the TPS6593-Q1 device. The supply of the bucks, the PVIN_Bx pins, must connect to the VCCA pin externally. The supply of the LDOs, the PVIN_LDOx pins, may connect to the VCCA pin or a buck output which is at a lower voltage level than the VCCA. The voltage output of each power resource is continuously monitored by a dedicated analog monitor on an independent reference voltage domain. An unused regulator can also be used as a voltage monitor for an external rail by connecting the external rail to the FB_Bn the VOUT_LDOn pin. #GUID-4B7B2915-7E2F-4669-92C2-3E88664B9019/SLVSE825742 lists the power resources provided by the TPS6593-Q1 device.

All of the buck converters support the following features: Automatic mode control based on the loading (PFM or PWM mode) or Forced-PWM mode operation External clock synchronization option to minimize crosstalk Optional spread spectrum technique to reduce EMI Soft start AVS support with configurable slew-rate Windowed undervoltage and overvoltage monitors with configurable threshold Windowed voltage monitor for external supply when the buck converter is inactive Output Current Limit Short-to-Ground Detection on SW_Bx pins at start-up of the buck regulator When the outputs of these buck converters are combined in multi-phase configuration, it also supports the following features: Current balancing between the phases of the converter Differential voltage sensing from point of the load Phase shifted outputs for EMI reduction Optional dynamic phase shedding or adding There are two modes of operation for the buck converter, depending on the required output current: pulse-width modulation (PWM) and pulse-frequency modulation (PFM). The converter operates in PWM mode at high load currents of approximately 600 mA or higher. Lighter output current loads cause the converter to automatically switch into PFM mode for reduced current consumption. The device avoids pulse skipping and allows easy filtering of the switch noise by external filter components when forced-PWM mode is selected (BUCKn_FPWM = 1). The forced-PWM mode is the recommended mode of operation for the buck converter to achieve better ripple and transient performance. The drawback of this forced-PWM mode is the higher quiescent current at low output current levels. When operating in PWM mode the phases of a multi-phase regulator are automatically added or shed based on the load current level. The forced multi-phase mode can be enabled for lower ripple at the output. shows a block diagram of a single core. shows the interleaving switching action of the multi-phase converters. BUCK Core Block Diagram Example of PWM Timings, Inductor Current Waveforms, and Total Output Current in 4-Phase Configuration.     (1) Multi-Phase Operation and Phase-Adding or Shedding The 4-phase converters (BUCK1, BUCK2, BUCK3, and BUCK4) switches each channel 90° apart under heavy load conditions. As a result, the 4-phase converter has an effective ripple frequency four times greater than the switching frequency of any one phase. In the same way, 3-phase converter has an effective ripple frequency three times greater and 2-phase converter has an effective ripple frequency two times greater than the switching frequency of any one phase; the parallel operation, however, decreases the efficiency at light load conditions. The TPS6593-Q1 can change the number of active phases to optimize efficiency for the variations of the load in order to overcome this operational inefficiency. The process in which the multi-phase buck regulator in case of increasing load current automatically increases the number of active phases is called phase adding. The process in which the multi-phase buck regulator in case of decreasing load current automatically decreases the number of active phases is called phase shedding. The concept is shown in . The converter can be forced to multi-phase operation by the BUCKn_FPWM_MP bit in BUCKn_CTRL1 register. If the regulator operates in forced multi-phase mode , each phase automatically operates in the forced-PWM mode. If the multi-phase operation is not forced, the number of phases are added and shed automatically to follow the required output current. Multiphase BUCK Converter Efficiency vs Number of Phases (Converters in PWM Mode) (1) Transition Between PWM and PFM Modes The forced-PWM mode operation with phase-adding or shedding optimizes efficiency at mid-to-full load. TheTPS6593-Q1 converter operates in PWM mode at load current of approximately 600 mA or higher. The device automatically switches into PFM mode for reduced current consumption when forced-PWM mode is not enabled (BUCKn_FPWM = 0) at lighter load-current levels. A high efficiency is achieved over a wide output-load-current range by combining the PFM and the PWM modes. Multi-Phase BUCK Regulator Configurations The control of the multi-phase regulator settings is done using the control registers of the primary BUCK regulator in the multi-phase configuration. The TPS6593-Q1 ignores settings in the following registers of the secondary and, if used, the tertiary and quaternary BUCK regulators : BUCKn_CTRL register, except BUCKn_VMON_EN BUCKn_CONF register BUCKn_VOUT_1 and BUCKn_VOUT_2 registers BUCKn_PG_WINDOW register Interrupt bits related to the secondary and, if sued, the tertiary and quaternary BUCK regulator, except BUCKn_ILIM_INT, BUCKn_ILIM_MASK and BUCKn_ILIM_STAT #GUID-E61220E0-AB07-48B8-BBB5-1EEC54C6C2D1/SLVSE828295 shows the supported Multi-Phase BUCK regulator configurations and the assigned primary BUCK regulator in each configuration.

The configuration registers are user-configurable for the voltage monitor function on BUCK3 and BUCK4 in a 4-phase configuration and BUCK3 in a 3-phase configuration. The UV/OV voltage monitors of these BUCK3 and BUCK4 regulators can be used to monitor external supply rails, by connecting these external rails to the FB_Bn pins of these BUCK3 and BUCK4 regulators. The following list of registers and register bits for BUCK3 and BUCK4 can be used to enable and set the target voltage for the external voltage monitoring function under such configuration: BUCKn_VMON_EN bit BUCKn_VSEL bit BUCKn_SLEW_RATE BUCKn_VOUT_1 and BUCKn_VOUT_2 registers BUCKn_PG_WINDOW register Customers are responsible for the values set in these registers when using BUCK3 or BUCK4 to monitor an external supply under the 3-phase or 4-phase configuration. If the voltage monitor function is not used under such a scenario, the FB_Bn pins must be connected to the reference ground, and the BUCKn_VMON_EN bits must be set to '0'. Spread-Spectrum Mode The TPS6593-Q1 device supports spread-spectrum modulation of the switching clock signal used by the BUCK regulators. Three factory-selectable modulation modes are available: the first mode is modulation from external input clock at the SYNCCLKIN pin; the second mode is modulating the input clock at the SYNCCLKIN pin using the DPLL; the third mode is modulating the internal 20-MHz RC-Oscillator clock using the DPLL. The spread-spectrum modulation mode is pre-configured in NVM. Changing this modulation mode during operation is not supported. The modulation frequency range is limited by the DPLL bandwidth. The max frequency spread for the input clock to the DPLL is ±18% to secure parametric compliance of the BUCK output performance. The internal modulation is inactive by default and can be enabled and configured after power up. Internal modulation is activated by setting the SS_EN control bit. The internal modulation must be inactive (SS_EN = 0) when changing the following parameter: SS_DEPTH[1:0] – Spread Spectrum modulation depth When internal modulation is enabled and configured, it can be made inactive by the system MCU during operation. The device transition to different mission states does not impact internal modulation when it is enabled and configured. Adaptive Voltage Scaling (AVS) and Dynamic Voltage Scaling (DVS) Support An AVS or a DVS voltage value can be configured by the attached MCU after the BUCK regulator is powered up to the default output voltage selected in register BUCKn_VSET1, that loads its default value from NVM. The purpose of the AVS/DVS voltage is to set the BUCK output voltage to enable optimal efficiency and performance of the attached SoC. All of BUCK regulators in the TPS6593-Q1 device support AVS and DVS voltage scaling changes. Once the AVS/DVS voltage value is written into the BUCKn_VSET1 or BUCKn_VSET2 register, and the MCU sets the BUCKn_VSEL register to select the AVS/DVS voltage, the output of the BUCK regulator remains at the AVS/DVS voltage level instead of the default voltage from NVM until one of the following events occur: Error that causes the device to re-initialize itself through a power cycle after reaching the SAFE RECOVERY state Error that causes the device to execute warm reset MCU configures the device to enter the LP STANDBY state shows the arbitration scheme for loading the output level of the BUCK regulator from the AVS register using the BUCKn_VSET control registers. AVS/DVS Configuration Register Arbitration Diagram The digital control block automatically updates the OV and UV threshold of the BUCK output voltage monitor during the AVS or DVS voltage change. When the output voltage is increased, the OV threshold is updated at the same time the BUCKn_VSETx is updated to the AVS voltage level, while the UV threshold is updated after a delay calculated by . When the output voltage is decreased, the UV threshold is updated at the same time the BUCKn_VSETx is updated to the AVS voltage level, while the OV threshold is updated after a delay calculated by . tPG_OV_UV_DELAY = (dV / BUCKn_SLEW_RATE) + tsettle_Bx In order to prevent erroneous voltage monitoring, the digital block also temporarily masks the results of the OV and UV monitor from the regulator output when the BUCK regulator is enabled and the voltage is rising to the BUCKn_VSETx level. The duration of the mask starts from the time the BUCK regulator is enabled. The BUCK OV monitor output is masked for a fixed delay time of tPG_OV_GATE, that is approximately 115 µs – 128 µs. The UV monitor output is masked for the time duration calculated by . The 370-µs additional delay time in the formula includes the start-up delay of the BUCK regulator, and the fixed delay after the ramp. tPG_UV_GATE = (BUCKn_VSET / BUCKn_SLEW_RATE) + 370 µs Because output capacitance, forward and negative current limits and load current of the BUCK regulator may affect the slew rate of the BUCK regulator output voltage, the delay time of tPG_UV_GATE may not be sufficient long for the slower slew rate setting when the target BUCK regulator output voltage is higher. Please refer to the PMIC user's guide for detail information about the supported voltage level and slew rate setting combinations of a particular orderable part number. and are timing diagrams illustrating the voltage change for AVS and DVS enabled BUCK regulators and the corresponding OV and UV monitor threshold changes.

The High-Side Current Limit, also referred to as Forward Current Limit, is for BUCK1..4 adjustable between 2.5 A and 5.5 A with 1-A steps with register bits BUCKx_ILIM[3:0]. For BUCK5, this Forward Current Limit has selectable levels 2.5 A and 3.5 A with register bits BUCK5_ILIM[3:0]. The Low-Side Current Limit, also referred to as Negative Current Limit, has a fixed value of typical 2 A. SW_Bx Short-to-Ground Detection Each BUCK regulator includes a SW_Bx Short-to-Ground Detection. This SW_Bx Short-to-Ground Detection monitors whether the SW_B1...SW_B5 pins have a short-to-ground condition, either caused by external short on these pins or caused by a short in the low-side power-FET of the BUCK regulator. This SW_Bx Short to Ground Detection is activated before the power-up of the BUCK regulator. When this function detects a short-to-ground condition on the SW_B1...SW_B5 pins, the TPS6593-Q1 aborts the power-up sequence and sets the corresponding interrupt bits BUCKx_SC_INT (x=1...5). After this, the TPS6593-Q1 transitions to the SAFE RECOVERY state, after which it performs an attempt to restart as described in . Sync Clock Functionality The TPS6593-Q1 device contains a SYNCCLKIN (GPIO10) input to synchronize switching clock of the BUCK regulator with the external clock. The block diagram of the clocking and PLL module is shown in . The external clock is selected when the external clock is available, and SEL_EXT_CLK = '1'. The nominal frequency of the external input clock is set by EXT_CLK_FREQ[1:0] bits in the NVM and it can be 1.1 MHz, 2.2 MHz, or 4.4 MHz. The external SYNCCLKIN clock must be inside accuracy limits (–18%/+18%) of the typical input frequency for valid clock detection. The EXT_CLK_INT interrupt is generated in case the external clock is expected (SEL_EXT_CLK = 1), but it is not available or the clock frequency is not within the valid range. The TPS6593-Q1 device can also generate a clock signal, SYNCCLKOUT, for external device use. The SYNCCLKOUT_FREQ_SEL[1:0] selects the frequency of the SYNCCLKOUT. Note: SYNCCLKOUT_FREQ_SEL[1:0] must stay static while SYNCCLKOUT is used, as changing the output frequency selection can cause glitches on the clock output. The SYNCCLKOUT is available through GPIO8, GPIO9, or GPIO10. Sync Clock and DPLL Module Low Dropout Regulators (LDOs) All of the LDO regulators in the TPS6593-Q1 device can be supplied by the system supply or another pre-regulated voltage source which are within the specified VIN range. The PVIN_LDOn voltage level must be equal or less than the VCCA voltage level to ensure proper operation of the LDOs. The default output voltages of all LDOs are loaded from the NVM memory and can be configured by the LDOn_VSET[7:0]. There is no hardware protection to prevent software from selecting an improper output voltage if the minimum level of PVIN_LDOn is lower than the dropout voltage of the LDO regulator in addition to the configured LDO output voltage. In such conditions, the output voltage droops to near the PVIN_LDOn level. Writing a RESERVED value to the LDOn_VSET[7:0] register bits causes a LDOn_OV_INT or LDOn_UV_INT interrupt. The LDO regulators do not have slew rate control for voltage ramp; by setting the LDOn_SLOW_RAMP bit to '1', however, the ramp up speed of the regulator output voltage is < 3 V/ms. If an LDO is not needed, its associated UV/OV Voltage Monitor can be used to monitor an external voltage rail by connecting the external rail to the VOUT_LDOn pin. The voltage level of the monitored external rail must be within the PGOOD monitor range of the LDOn_VSET[7:0] of the LDO. If an external resistor divider is necessary in this case, the user must take into account the input impedance at the VOUT_LDOn pin (as shown in ), and adjust the resistor values to compensate for the voltage shift. Impedance at the VOUT_LDOn Pins LDOVINT The LDOVINT voltage regulator is dedicated to supply the digital and analog functions of the TPS6593-Q1 device, which are not required to be always-on and can be turned-off when the device is in low power states. The LDOVINT voltage regulator is automatically turned on and off as needed if LP_STANDBY_SEL = '1'. The automatic control optimizes the overall current consumption when the device is in low power LP_STANDBY state. The LDOVINT voltage regulator is dedicated for internal use only, and cannot be used to support external loads. An output filtering capacitor must be connected at the VOUT_LDOVINT pin. Do not connect any other components or external loads to this VOUT_LDOVINT pin. LDOVRTC The LDOVRTC voltage regulator supplies always-on functions, such as wake-up functions. This power resource is active as soon as a valid VCCA is present. The LDOVRTC voltage regulator is dedicated for internal use only, and cannot be used to support external loads. An output filtering capacitor must be connected at the VOUT_LDOVRTC pin. Do not connect any other components or external loads to this VOUT_LDOVRTC pin. This voltage regulator is enabled in normal mode or backup mode. The LDOVRTC voltage regulator functions in normal mode when supplied from the main system power rail and is able to supply the input buffers of GPIO3 and GPIO4, the digital components, the crystal, and the RTC calendar module of the TPS6593-Q1 device. The LDOVRTC voltage regulator remains on in BACKUP state when VCCA is below the VCCA_UVLO level, and the backup power source is above the LDOVRTC_UVLO level. Only the 32 kHz crystal and the RTC counter are activated in the BACKUP state. The RTC calendar function remains active in the LP_STANDBY state, but the interrupt functions are reduced to maintaining the wake up functions only. The RTC calendar and interrupt functions are fully activated in the mission states. The customer has the option to enable the shelf mode by setting the LDORTC_DIS bit to 1 while the device is in the MISSION state and the I2C bus is in operation and ramp down VCCA to 0 V immediately after the I2C write has completed. This shelf mode forces the device to skip the BACKUP state and enters the NO SUPPLY state under VCCA_UVLO condition. This mode is useful to prevent the continual draining of the backup power source when the 32 KHz crystal and RTC counter functions are no longer needed. LDO1, LDO2, and LDO3 A 20220110 Added LDO1, LDO2, LDO3 Current Limit descriptionyes The LDO1, LDO2 and LDO3 regulators can deliver up to 500 mA of current, with a configurable output range of 0.6 V to 3.3 V in 50-mV steps. These 3 LDO regulators also support bypass mode, which allows an input voltage at the PVIN_LDOn to show up at the VOUT_LDOn pin. This feature allows the LDOs to be configured as load switches with power sequencing control. Similar to the buck regulators mentioned in , the UV/OV Voltage Monitor of an un-used LDO regulator can also be used to monitor an external voltage rail by connecting the external rail to the VOUT_LDOn pin. The bypass capability to connect the input voltage to the output in bypass mode is supported when the input voltage is within the 1.7 V to 3.5 V range. This bypass capability also allows the LDO to switch from 3.3 V in bypass mode to 1.8 V in LDO mode or from 1.8 V in LDO mode to 3.3 V in bypass mode for an SD card I/O supply. The LDO1, LDO2 and LDO3 regulator include a Current-Limit to protect the internal Power-FET against overcurrent. This Current-Limit has a fixed value between 700 mA and 1800 mA. It is important to wait until the LDO has settled on the target voltage from the previous change when changing the LDO output voltage setting. The worst-case voltage scaling time for LDO1, LDO2, and LDO3 is 63 µs x (7 + the number of 50-mV steps to the new target voltage). #GUID-EC409DDC-2E1D-4E58-8C0F-5BA31078220E/X2414 shows the coding used to select the output voltage for LDO1, LDO2, and LDO3.

This LDO is specifically designed to supply noise sensitive circuits. This supply can be used to power circuits such as PLLs, oscillators, or other analog modules that require low noise on the supply. LDO4 does not support bypass mode. However, if the LDO4 output voltage is not used, the associated UV/OV Voltage Monitor of this regulator can be used as to monitor an external voltage rail by connecting this external voltage rail to the VOUT_LDO4 pin. The LDO4 regulator includes a Current-Limit to protect the internal Power-FET against overcurrent. This Current-Limit has a fixed value between 400 mA and 900 mA. #GUID-7532B08A-787D-48A5-866A-CF9357CABD43/X1331 shows the coding used to select the output voltage for LDO4.

Thermal warning can also be included in the result of the PGOOD monitor if it is not masked. Either voltage and current monitoring or only voltage monitoring can be selected for PGOOD indication. This selection is set by the PGOOD_SEL_BUCKn register bits for each BUCK regulator (select primary phase for multi-phase regulator), and is set by the PGOOD_SEL_LDOn register bits for each LDO regulator. When voltage and current are monitored, an active PGOOD signal active indicates that the regulator output is inside the Power-Good voltage window and that load current is below the current limit. If only voltage is monitored, then the current monitoring is ignored for the PGOOD signal. The PGOOD signal represents the momentary status of the included indications without latching. If the PGOOD signal goes low due to an indicated warning or error condition, the PGOOD signal goes high immediately when the previous indicated warning or error condition is no longer present. The BUCKn_VMON_EN bit enables the overvoltage (OV) , undervoltage (UV) and short-circuit (SC) comparators. The current limit (ILIM) comparator of each BUCK regulator is activated as soon as the corresponding BUCK regulator is enabled. In order to add the current limit indication of a BUCK regulator to the PGOOD signal, the BUCKn_VMON_EN bit of the corresponding BUCK regulator must be set. For LDO regulators, the LDOn_VMON_EN bit enables the OV and UV, short-circuit (SC) comparators. The current limit (ILIM) comparator of each LDO regulator is activated as soon as the corresponding LDO regulator is enabled. In order to add the current limit indication of an LDO to the PGOOD signal, the LDOn_VMON_EN bit of the corresponding LDO regulator must be set. When a BUCK or an LDO is not needed as a regulated output, it can be used as a voltage monitor for an external rail. For BUCK converters, if the BUCKn_VMON_EN bit remains '1' while the BUCKn_EN bit is '0', it can be used as a voltage monitor for an external rail that is connected to the FB_Bn pin of the BUCK regulator. For LDO regulators, if the LDOn_VMON_EN bit remains '1' while the LDOn_EN bit is '0', it can be used as a voltage monitor for an external rail which is connected to the VOUT_LDOn pin. When the voltage monitor for a BUCK or LDO regulator is inactive, the output of the corresponding monitor is automatically masked to prevent it from forcing PGOOD inactive. The masking allows PGOOD to be connected to other open-drain power good signals in the system. The VCCA input voltage monitoring is enabled with VCCA_VMON_EN bit. The monitoring can be enabled by an NVM default setting, that starts the monitoring of the VCCA voltage after the device passes the BOOT BIST state. The reference voltage for the VCCA monitor can be set by the VCCA_PG_SET bit to either 3.3 V or 5 V. The PGOOD_SEL_VCCA register bit selects whether or not the result of the VCCA monitor is included in the PGOOD monitor output signal. An NVM option is available to gate the PGOOD output with the nRSTOUT and the nRSTOUT_SoC signals, the intended reset signals for the safety MCU and the SoC respectively. When PGOOD_SEL_NRSTOUT = '1', the PGOOD pin is gated by the nRSTOUT signal. When PGOOD_SEL_NRSTOUT_SOC = '1', the PGOOD pin is gated by the nRSTOUT_SoC signal. This option allows the PGOOD output to be used as an enable signal for external peripherals. The outputs of the voltage monitors from all the output rails are combined, and PGOOD is active only if all the sources shows active status. The type of output voltage monitoring for PGOOD signal is selected by PGOOD_WINDOW bit. If the bit is 0, only undervoltage is monitored; if the bit is 1, then undervoltage and overvoltage are monitored. The polarity and the output type (push-pull or open-drain) are selected by PGOOD_POL and GPIO9_OD bits. shows the Power-Good generation block diagram, and shows the Power-Good waveforms. PGOOD Block Diagram PGOOD Waveforms The OV and UV threshold of the voltage monitors of the BUCK regulators and the LDO regulators are updated automatically by the digital control block when the output voltage setting changes. When the output voltage of the regulator is increased, the OV threshold is updated at the same time the _VSET of the regulator is changed. The UV threshold is updated after a delay calculated by the delta voltage change and the slew rate setting. When the output voltage is decreased, the UV threshold is updated at the same time the _VSET of the regulator is changed. The OV threshold is updated after a delay calculated by the delta voltage change and the slew rate setting. The OV and UV threshold of the BUCK and LDO output voltage monitors are calculated based on the target output voltage set by the corresponding BUCKn_VSET1, BUCKn_VSET2, or LDOn_VSET registers, and the deviation from the target output voltage set (the voltage window) by the corresponding BUCKn_UV_THR, BUCKn_OV_THR, LDOn_UV_THR, and the LDOn_OV_THR registers. For the OV and UV threshold of BUCK and LDO output monitors to update with the correct timing, the following operating procedures must be followed when updating the _VSET values of the regulators to avoid detection of OV/UV fault: BUCK and LDO regulators must be enabled at the same time as or earlier than as their VMON New voltage level must not be set before the start-up has finished New voltage level must not be set before the previous voltage change (ramp plus settling time) has completed The voltage monitors of unused BUCK or LDO regulators can be used for external supply rails monitoring. In three-phase configuration, the Voltage Monitor of BUCK3 (on FB_B3 pin) becomes a free available resource for monitoring an external supply voltage. In four-phase configuration, the Voltage Monitor of both BUCK3 (on FB_B3 pin) and BUCK4 (on FB_B4 pin) become free available resources for monitoring two external supply voltages.. The target output voltage is set by the corresponding BUCKn_VSET1, BUCKn_VSET2, or LDOn_VSET registers, and the deviation from the target output voltage set (the voltage window) by the corresponding BUCKn_UV_THR, BUCKn_OV_THR, LDOn_UV_THR, and the LDOn_OV_THR registers. Following aspects need to be taken into account if Voltage Monitors of unused BUCK or LDO regulators are used for monitoring external supply rails: For voltage monitors of unused LDO regulators: the voltage level applied at the VOUT_LDOx pin, inclusive expected tolerances, must be below the supply voltage applied at the PVIN_LDOx pin For voltage monitors of unused BUCK and LDO regulators: the maximum nominal supply voltage of the monitored supply rail is 3.3V For voltage monitors of unused BUCK regulators and for voltage monitors of BUCK3 and/or BUCK4 regulators if used in a three-phase or four-phase configuration: the configured values for the BUCKn_VSET and the BUCKn_SLEW_RATE determine the delay-time for the voltage monitoring to become active after the corresponding BUCKn_VMON_EN bit is set. See equation (2) in . If BUCK3 and/or BUCK4 regulators are used in a three-phase or four-phase configuration: even though the values for the BUCK1_VSET and BUCK1_SLEW_RATE bits determine the output voltage and slew-rate of the three-phase or four-phase output rail, the values for BUCK3_VSET respectively BUCK4_VSET and BUCK3_SLEW_RATE respectively BUCK4_SLEW_RATE bits determine the power-good level and the voltage monitoring delay time for the BUCK3 respectively BUCK4 Voltage Monitors. For voltage monitors of unused LDO regulators: the delay-time for the voltage monitoring to become active after the corresponding LDOn_VMON_EN bit is set it 601..606μs. Thermal Monitoring The TPS6593-Q1 device includes several thermal monitoring functions for internal thermal protection of the PMIC. The TPS6593-Q1 device integrates thermal detection modules to monitor the temperature of the die. These modules are placed on opposite sides of the device and close to the LDO and BUCK modules. An over-temperature condition at either module first generates a warning to the system, and if the temperature continues to rise, then a switch-off of the PMIC device can occur before damage to the die. Three thermal protection levels are available. One of these protections is a thermal warning function described in , that sends an interrupt to software. Software is expected to close any noncritical running tasks to reduce power. The second and third protections are the thermal shutdown (TS) function described in , that begins device shutdown orderly or immediately. Thermal monitoring is automatically enabled when one of the BUCK or LDO outputs is enabled within the mission states. The thermal monitoring is deactivated in the LP_STANDBY state, when only the internal regulators are enabled, to minimize the device power consumption. Indication of a thermal warning event is written to the TWARN_INT register. The current consumption of the thermal monitoring can be decreased in the mission states when the low power dissipation is important. If LPM_EN bit is set and the temperature is below thermal warning level in all thermal detection modules, only one thermal detection module is monitored. If the temperature rises in this module, monitoring in all thermal detection modules is started. If the die temperature of the TPS6593-Q1 device continues to rise while the device is in mission state, an TSD_ORD_INT or TSD_IMM_INT interrupt is generated, causing a SEVERE or MODERATE error trigger (respectively) in the state machine. While the sequencing and error handling is NVM memory dependent, TI recommends a sequenced shutdown for MODERATE errors, and an immediate shutdown, using resistive discharging, for SEVERE errors to prevent damage to the device. The system cannot restart until the temperature falls below the thermal warning threshold. Thermal Warning Function The thermal monitor provides a warning to the host processor through the interrupt system when the temperature reaches within a cautionary range. The threshold value must be set to less than the thermal shutdown threshold. The integrated thermal warning function provides the MCU an early warning of over-temperature condition. This monitoring system is connected to the interrupt controller and can send an TWARN_INT interrupt when the temperature is higher than the preset threshold. The TPS6593-Q1 device uses the TWARN_LEVEL register bit to set the thermal warning threshold temperature at 130°C or 140°C. There is no hysteresis for the thermal warning level. When the power-management software triggers an interrupt, immediate action must be taken to reduce the amount of power drawn from the PMIC device (for example, noncritical applications must be closed). Thermal Shutdown The thermal shutdown detector monitors the temperature on the die. If the junction reaches a temperature at which damage can occur, a switch-off transition is initiated and a thermal shutdown event is written into a status register. There are two levels of thermal shutdown threshold. When the die temperature reaches the TSD_orderly level, the TPS6593-Q1 device performs an orderly shutdown of all output power rails. If the die temperature raises rapidly and reaches the TSD_imm level before the orderly shutdown process completes, the TPS6593-Q1 device performs an immediate shutdown with activated pull-down on all output power rails, in order to turn off all of the output power rails as rapidly as possible. After the thermal shutdown takes place, the system cannot restart until the die temperature is below the thermal warning threshold. Backup Supply Power-Path The LDOVRTC is supplied from either the VBACKUP (backup supply from either coin-cell or super-cap) input or VCCA. The power-path is designed to prioritize VCCA to maximize the life of the backup supply. When VCCA drops below the VCCA_UVLO threshold, the device shuts down all rails except the LDOVRTC, and enters the BACKUP mode. At this point, the Backup Supply Power-Path switches to the VBACKUP as the input of LDOVRTC. When the voltage of VCCA returns to level above the VCCA_UVLO threshold level, the power-path switches the input of LDOVRTC back to VCCA. When both the VCCA voltage drop below the VCCA_UVLO threshold, and the VBACKUP voltage drops below 1.7V (RTC_LDO_UVLO threshold), the LDOVRTC is turned OFF and the digital core is reset, which forces the device into the NO SUPPLY state. Note: a backup supply is not required for the device to operate. The device skips the BACKUP state if the VBACKUP pin is grounded. General-Purpose I/Os (GPIO Pins) The TPS6593-Q1 device integrates eleven configurable general-purpose I/Os that are multiplexed with alternative features as listed in For GPIOs characteristics, refer to Electrical Characteristics tables for Digital Input Signal Parameters and Digital Output Signal Parameters. When configured as primary functions, all GPIOs are controlled through the following set of registers bits under the individual GPIOn_CONF register. GPIOn_DEGLITCH_EN: Enables the 8 µs deglitch time for each GPIO pin (input) GPIOn_PU_PD_EN: Enables the internal pull up or pull down resistor connected to each GPIO pin GPIOn_PU_SEL: Selects the pull up or the pull down resistor to be connected when GPIOn_PU_PD_EN = '1'. '1' = pull-up resistor selected, '0' = pull-down resistor selected GPIOn_OD: Configures the GPIO pin (output) as: '1' = open drain, '0' = push-pull GPIOn_DIR: Configures the input or output direction of each GPIO pin Each GPIO event can generate an interrupt on a rising edge, falling edge, or both, configured through the GPIOn_FALL_MASK and the GPIOn_RISE_MASK register bits. A GPIO-interrupt applies when the primary function (general-purpose I/O) has been selected and also for the following alternative functions: nRSTOUT_SOC PGOOD nERR_MCU nERR_SoC TRIG_WDOG DISABLE_WDOG NSLEEP1, NSLEEP2 WKUP1, WKUP2 LP_WKUP1, LP_WKUP2 The GPIOn_SEL[2:0] register bits under the GPIOn_CONF registers control the selection between a primary and an alternative function. When a pre-defined function is selected, some predetermined IO characteristics (such as pullup, pulldown, push-pull or open drain) for the pin are enforced regardless of the settings of the associated GPIO configuration register. Please note that if the GPIOn_SEL[2:0] is changed during device operation, a signal glitch may occur which may cause digital malfunction, especially if it involves a clock signal such as SCL_I2C2, CLK32KOUT, SCL_SPMI, SYNCCLKIN, or SYNCCLKOUT. Please refer to for more detail on the predetermined IO characteristics for each pre-defined digital interface function. All GPIOs can be configured as a wake-up input when it is configured as a WKUP1 or a WKUP2 signal. Only GPIO3 and GPIO4 can be configured as LP_WKUP1 or LP_WKUP2 signal so that they can be used to wake-up the device from LP_STANDBY state. All GPIOs can also be configured as a NSLEEP1 or a NSLEEP2 input. For more information regarding the usage of the NSLEEPx pins and the WKUPx pins, please refer to and . Any of the GPIO pin can also be configured as part of the power-up sequence to enable external devices such as external BUCKs when it is configured as a general-purpose output port. The nINT pin, the EN_DRV pin, the nRSTOUT pin and the GPIO pin assigned as nRSTOUT_SOC have readback monitoring to detect errors on the signals. The monitoring of the EN_DRV pin checks for mismatch in both low and high levels. For the nINT pin, the nRSTOUT pin and the GPIO pin assigned as nRSTOUT_SOC, the readback monitoring only checks for mismatches in the low level, therefore it is allowed to combine these signals with other external pull-down sources. The readback mismatch is continuously monitored without deglitch circuitry during operation, and the monitoring is gated for tgate_readback period when the signal state is changed or when a new function is selected for the GPIO pin with the GPIOn_SEL bits. NINT_READBACK_INT, EN_DRV_READBACK_INT, NRSTOUT_READBACK_INT, and NRSTOUT_SOC_READBACK_INT are the interrupt bits that are set in an event of a readback mismatch for these pins, respectively.All GPIO pin are set to generic input pins with resistive pull-down before NVM memory is loaded during device power up. Therefore, if any GPIOs has external pull-up resistors connecting to a voltage domain that is energized before the NVM memory is loaded, the GPIO pin is pulled high before the configuration for the pin is loaded from the NVM. For GPIO pins with internal pull down enabled, additional leakage current flows into the GPIO pin if this pin is pulled-up to a voltage higher than the voltage level of its output power domain. If the internal pull down must be enabled, please use a resistor divider to divide down the input voltage, or use a series resistor to connect to the input source and ensure the voltage level at the GPIO pin is below the voltage level of its output power domain. nINT, EN_DRV, and nRSTOUT Pins The nINT, EN_DRV and nRSTOUT pin, and the GPIO pin assigned as nRSTOUT_SoC are IO pins with dedicated functions. The nINT pin is the open drain interrupt output pin. More description regarding the function of this pin can be found under . The nRSTOUT pin, together with the GPIO pin assigned as nRSTOUT_SoC, are the system reset pins which can be configured as open-drain or push-pull outputs. These pins stay in the default low state until the PFSM of the TPS6593-Q1 sets the associated control bits NRSTOUT and NRSTOUT_SOC in the register map. These control bits NRSTOUT and NRSTOUT_SOC are set by the PFSM typically after the end of a power-up sequence. At the beginning of a power-down sequence, the PFSM clears these control bits NRSTOUT and NRSTOUT_SOC in order to pull-down the nRSTOUT and nRSTOUT_SoC pins before the ramp-down of the voltage rails. The purpose of the EN_DRV pin is to indicate that the TPS6593-Q1 has entered a safe state. The EN_DRV pin has an internal 10kΩ high-side pull-up to the VCCA supply. The TPS6593-Q1 pulls this EN_DRV pin to the default low state, and releases the pull-down when the MCU sets the ENABLE_DRV bit to '1'. Interrupts The interrupt registers in the device are organized in hierarchical fashion. The interrupts are grouped into the following categories: BUCK ERROR These interrupts indicate over-voltage (OV), under-voltage (UV), short-circuit (SC) and over-current (ILIM) error conditions found on the BUCK regulators . LDO ERROR These interrupts indicate OV, UV, and SC error conditions found on the LDO regulators, as well as OV and UV error conditions found on the VCCA supply. VMON ERROR These interrupts indicate OV and UV error conditions found on the VCCA supply. SEVERE ERROR These errors indicate severe device error conditions, such as thermal shutdown, PFSM sequencing and execution error and VCCA over-voltage, that causes the device to trigger the PFSM to execute immediate shutdown of all digital outputs, external voltage rails and monitors, and proceed to the Safe Recovery State. MODERATE ERROR These interrupts provide warnings to the system to indicate multiple restart attempts from SAFE RECOVERY state exceeding the allowed recovery count, multiple warm-reset executions exceeding the allowed recovery count, detection of long press nPWRON button, SPMI communication error, register CRC error, BIST failure, read-back error on nRSTOUT or nINT pins, or junction temperature reaching orderly shutdown level. These warning causes the device to trigger the PFSM to execute orderly shutdown of all digital outputs, external voltage rails and monitors, and proceed to the SAFE RECOVERY state.The SEVERE ERROR and the MODERATE ERROR are handled in NVM memory but TI requires that the NVM pre-configurable finite state machine (PFSM) settings always follow this described error handling to meet device specifications. MISCELLANEOUS WARNING These interrupts provide information to the system to indicate detection of WDOG or ESM errors, die temperature crossing thermal warning threshold, device passing BIST test, or external sync clock availability. START-UP SOURCE These interrupts provide information to the system on the mechanism that caused the device to start up, which includes FSD, RTC alarm or timer interrupts, the activation of the ENABLE pin or the nPRWON pin button detection. GPIO DETECTION These interrupts indicate a High-Level or Rising-Edge detection, or indicate a Low-Level or Falling-Edge detection at the GPIO1 through GPIO11 pins. FSM ERROR INTERRUPT These interrupts indicate the detection of an error that causes the device mission state changes. All interrupts are logically combined on a single output pin, nINT (active low). The host processor can read the INT_TOP register to find the interrupt registers to find out the source of the interrupt, and write '1' to the corresponding interrupt register bit to clear the interrupt. This mechanism ensures when a new interrupt occurs while the nINT pin is still active, all of the corresponding interrupt register bits retain the interrupt source information until it is cleared by the host. Hierarchical Structure of Interrupt Registers shows the hierarchical structure of the interrupt registers according to the categories described above. The purpose of this register structure is to reduce the number of interrupt register read cycles the host has to perform in order to identify the source of the interrupt. Summary of Interrupt Signals summarizes the trigger and the clearing mechanism for all of the interrupt signals. This table also shows which interrupt sources can be masked by setting the corresponding mask register to '1'. When an interrupt is masked, the interrupt bit is not updated when the associated event occurs, the nINT line is not affected, and the event is not recorded. If an interrupt is masked after the event occurred, the interrupt register bit reflects the event until the bit is cleared. While the event is masked, the interrupt register bit is not over-written when a new event occurs.

The actual results can be configured differently in NVM memory. TI recommends reviewing of the system and device functional safety goal and documentation before deviating from these recommendations. Interrupt is generated during clock detector operation and in case clock is not available when clock detector is enabled. This event does not occur if RECOV_CNT_THR = 0, even though RECOV_CNT continues to accumulate and increase, and eventually saturates when it reaches the maximum count of 15. Due to a digital logic errata in the device, a write or read SPI command which coincide with the rising edge of the CS signal may not cause the COMM_FRM_ERR_INT interrupt. I2C1, I2C2, or SPI address error only occur in safety applications if the interface CRC feature is enabled, when both I2C1_SPI_CRC_EN and I2C2_CRC_EN are set to '1'. RTC General Description The RTC is driven by the 32-kHz oscillator and it provides the alarm and time-keeping functions. The main functions of the RTC block are: Time information (seconds, minutes, and hours) in binary-coded decimal (BCD) code Calendar information (day, month, year, and day of the week) in BCD code up to year 2099 Configurable interrupts generation; the RTC can generate two types interrupts which can be enabled and masked individually: Timer interrupts periodically (1-second, 1-minute, 1-hour, or 1-day periods) Alarm interrupt at a precise time of the day (alarm function) Oscillator frequency calibration and time correction with 1/32768 resolution shows the RTC block diagram. RTC Block Diagram Time Calendar Registers All the time and calendar information is available in the time calendar (TC) dedicated registers: SECONDS_REG, MINUTES_REG, HOURS_REG, DAYS_REG, WEEKS_REG, MONTHS_REG, and YEARS_REG. The TC register values are written in BCD code. Year data ranges from 00 to 99. Leap Year = Year divisible by four (2000, 2004, 2008, 2012, and so on) Common Year = Other years Month data ranges from 01 to 12. Day value ranges: 1 to 31 when months are 1, 3, 5, 7, 8, 10, 12 1 to 30 when months are 4, 6, 9, 11 1 to 29 when month is 2 and year is a leap year 1 to 28 when month is 2 and year is a common year Weekday value ranges from 0 to 6. Hour value ranges from 0 to 23 in 24-hour mode and ranges from 1 to 12 in AM or PM mode. Minutes value ranges from 0 to 59. Seconds value ranges from 0 to 59. Example: Time is 10H54M36S PM (PM_AM mode set), 2008 September 5; previous registers values are listed in #GUID-D55684DC-1A31-4EAF-B994-D540AFAEA45A/SWCS0959413: RTC Time Calendar Registers Example REGISTER CONTENT RTC_SECONDS 0x36 RTC_MINTURES 0x54 RTC_HOURS 0x10 RTC_DAYS 0x05 RTC_MONTHS 0x09 RTC_YEARS 0x08 RTC_WEEKS 0x06 The user can round to the closest minute, by setting the ROUND_30S register bit in the RTC_CTRL_REG register. TC values are set to the closest minute value at the next second. The ROUND_30S bit is automatically cleared when the rounding time is performed. Example: If current time is 10H59M45S, round operation changes time to 11H00M00S If current time is 10H59M29S, round operation changes time to 10H59M00S TC Registers Read Access TC register read access can be done in two ways: A direct read to the TC registers. In this case, there can be a discrepancy between the final time read and the real time because the RTC keeps running because some of the registers can toggle in between register accesses. Software must manage the register change during the reading. Read access to shadowed TC registers. These registers are at the same addresses as the normal TC registers. They are selected by setting the GET_TIME bit in the RTC_CTRL_REG register. When this bit is set, the content of all TC registers is transferred into shadow registers so they represent a coherent timestamp, avoiding any possible discrepancy between them. When processing the read accesses to the TC registers, the value of the shadowed TC registers is returned so it is completely transparent in terms of register access. TC Registers Write Access TC registers write accesses can be done while RTC is stopped. MCU can stop the RTC by the clearing the STOP_RTC bit of the control register and checking the RUN bit of the status to be sure that RTC is frozen. MCU then updates the TC values and restarts the RTC by setting the STOP_RTC bit, which ensures that the final written values are aligned with the targeted values. RTC Alarm RTC alarm registers (ALARM_SECONDS_REG, ALARM_MINUTES_REG, ALARM_HOURS_REG, ALARM_DAYS_REG, ALARM_MONTHS_REG, and ALARM_YEARS_REG) are used to set the alarm time or date to the corresponding generated ALARM interrupts. See for how these register values are written in BCD code, with the same data range as described for the TC registers. RTC Interrupts The RTC supports two types of interrupts: ALARM interrupt. This interrupt is generated when the configured date or time in the corresponding ALARM registers is reached. This interrupt is activated and deactivated by setting the IT_ALARM bit. It is important to set the IT_ALARM = 0 to deactivate the alarm interrupt prior to configuring the ALARM registers to prevent the interrupt from mis-firing. TIMER interrupt. This interrupt is generated when the periodic time (day, hour, minute, second) set in the EVERY bits of the RTC_INTERRUPTS register is reached. The first of the periodic interrupt occurs when the RTC counter reaches the next day, hour, minute, or second counter value. For example, if a timer interrupt is set for every hour at 2:59 AM, the first interrupt occurs at 3:00 AM instead of 3:59 AM. This interrupt is activated and deactivated by setting the IT_TIMER bit. It is important to set the IT_TIMER = 0 to disable the timer interrupt prior to configuring the periodic time value to prevent the interrupt from mis-firing. Both types of the RTC interrupts can be used to wake-up the device from the STANDBY state or the LP_STANDBY state when they are not masked. RTC 32-kHz Oscillator Drift Compensation The RTC_COMP_MSB_REG and RTC_COMP_LSB_REG registers are used to compensate for any inaccuracy of the 32-kHz clock output from the 32-kHz crystal oscillator. To compensate for any inaccuracy, MCU must perform an external calibration of the oscillator frequency by calculating the needed drift compensation compared to one hour time-period, and load the compensation registers with the drift compensation value. The compensation mechanism is enabled by the AUTO_COMP_EN bit in the RTC_CTRL_REG register. The compensation process happens after the first second of each hour. The time between second 1 and second 2 (T_ADJ) is adjusted based on the settings of the two RTC_COMP_MSB_REG and RTC_COMP_LSB_REG registers. These two registers form a 16-bit, 2 s complement value COMP_REG (from –32767 to 32767) that is subtracted from the 32-kHz counter as per the following formula to adjust the length of T_ADJ: (32768 - COMP_REG) / 32768. Therefore, this compensation mechanism can adjust the compensation with a 1/32768-second time-unit accuracy per hour and up to 1 second per hour. Software must ensure that these registers are updated before each compensation process (there is no hardware protection). For example, software can load the compensation value into these registers after each hour event, during second 0 to second 1, just before the compensation period, happening from second 1 to second 2. If the SET_32_COUNTER bit in the RTC_CTRL_REG register is set to '1', the internal 32-kHz counter is pre-loaded with the content of the RTC_COMP_MSB_REG and RTC_COMP_LSB_REG registers. This preloading of the internal 32-kHz counter can only be done when the RTC is stopped. shows the RTC compensation scheduling. RTC Compensation Scheduling Watchdog (WDOG) A 20220110 Watchdog (WDOG): added Q&A (question an answer) modeyes The watchdog monitors the correct operation of the MCU. This watchdog requires specific messages from the MCU in specific time intervals to detect correct operation of the MCU. The MCU can control the logic-level of the EN_DRV pin when the watchdog detects correct operation of the MCU. When the watchdog detects an incorrect operation of the MCU, the TPS6593-Q1 device pulls the EN_DRV pin low . This EN_DRV pin can be used in the application as a control-signal to deactivate the power output stages, for example a motor driver, in case of incorrect operation of the MCU. The watchdog has two different modes that are defined as follows: Trigger mode In trigger mode, the MCU applies a pulse signal with a minimum pulse width of tWD_pulse on the pre-assigned GPIO input pin to send the required watchdog trigger. To select this mode, the MCU must clear bit WD_MODE_SELECT. Watchdog Trigger Mode provides more details. Q&A (question and answer) mode In Q&A mode, the MCU sends watchdog answers through the I2C1 bus , I2C2 bus or SPI bus. (Which of these communication busses is to be used depends on the NVM configuration. Please refer to the user's guide of the orderable part number for further details). To select this mode, the MCU must set bit WD_MODE_SELECT. Watchdog Question-Answer Mode provides more details. Watchdog Fail Counter and Status The watchdog includes a watchdog fail counter WD_FAIL_CNT[3:0] that increments because of bad events or decrements because of good events. Furthermore, the watchdog includes two configurable thresholds: Fail-threshold (configurable through bits WD_FAIL_TH[2:0]) Reset-threshold (configurable through bits WD_RST_TH[2:0]) When the WD_FAIL_CNT[3:0] counter value is less than or equal to the configured Watchdog-Fail threshold (WD_FAIL_TH[2:0]) and bit WD_FIRST_OK=1, the MCU can set the ENABLE_DRV bit when no other error-flags are set. When the WD_FAIL_CNT[3:0] counter value is greater than the configured Watchdog-Fail threshold (WD_FAIL_CNT[3:0] > WD_FAIL_TH[2:0]), the device clears the ENABLE_DRV bit, sets the error-flag WD_FAIL_INT, and pulls the nINT pin low. When the WD_FAIL_CNT[3:0] counter value is greater than the configured Watchdog-Fail plus Watchdog-Reset threshold (WD_FAIL_CNT[3:0] > (WD_FAIL_TH[2:0] + WD_RST_TH[2:0])) and the watchdog-reset function is enabled (configuration bit WD_RST_EN=1), the device generates a WD_ERROR trigger in the state machine (see PFSM Trigger Selections) and sets the error-flag WD_RST_INT, and pulls the nINT pin low. Unless described otherwise in the user's guide of the orderable part number, this WD_ERROR trigger in the state machine causes the TPS6593-Q1 to execute a warm-reset, during which the nRSTOUT pin pulled low, and released after a pre-configured delay time. The device clears the WD_FAIL_CNT[3:0] each time the watchdog enters the Long Window. The status bits WD_FAIL_INT and WD_RST_INT are latched until the MCU writes a ‘1’ to these bits. Overview of Watchdog Fail Counter Value Ranges and Corresponding Device Status gives an overview of the Watchdog Fail Counter value ranges and the corresponding device status. Overview of Watchdog Fail Counter Value Ranges and Corresponding Device Status Watchdog Fail Counter value WD_FAIL_CNT[3:0] Device Status WD_FAIL_CNT[3:0] ≤ WD_FAIL_TH[2:0] MCU can set the ENABLE_DRV bit if WD_FIRST_OK=1 and no other error-flags are set. WD_FAIL_TH[2:0] < WD_FAIL_CNT[3:0] ≤ (WD_FAIL_TH[2:0] + WD_RST_TH[2:0]) The device sets error-flag WD_FAIL_INT and pulls the nINT pin low. Furthermore, , the device clears the ENABLE_DRV bit. WD_FAIL_CNT[3:0] > (WD_FAIL_TH[2:0] + WD_RST_TH[2:0]) If configuration bit WD_RST_EN=1, device generates WD_ERROR trigger in the state machine and reacts as defined in the PFSM, sets the error-flag WD_RST_INT, and pulls the nINT pin low. See Summary of Interrupt Signals for the interrupt handling of WD_RST. The WD_FAIL_CNT[3:0] counter responds as follows: When the Watchdog is in the Long-Window, the WD_FAIL_CNT[3:0] is cleared to 4’b0000 A good event decrements the WD_FAIL_CNT[3:0] by one before the start of the next Window-1 A bad event increments the WD_FAIL_CNT[3:0] by one before the start of the next Window-1 Refer to Watchdog Trigger Mode and Watchdog Q&A Related Definitions respectively for definitions of good events and bad events. Watchdog Start-Up and Configuration When the device releases the nRSTOUT pin, the watchdog starts with the Long Window. This Long Window has a time interval (tLONG_WINDOW) with a default value set in bits WD_LONGWIN[7:0]. As long as the watchdog is in the Long Window, the MCU can configure the watchdog through the following register bits: WD_EN to enable or disable the watchdog WD_LONGWIN[7:0] to increase the duration of the Long-Window time-interval WD_MODE_SELECT to select the Watchdog mode (Trigger mode or Q&A Mode) WD_PWRHOLD to activate the Watchdog Disable function (more detail in ) WD_RETURN_LONGWIN to configure whether to return to Long-Window or continue to the next sequence after the completion of the current watchdog sequence (more detail in ) WD_WIN1[6:0] to configure the duration of the Window-1 time-interval WD_WIN2[6:0] to configure the duration of the Window-2 time-interval WD_RST_EN to enable or disable the watchdog-reset function WD_FAIL_TH[2:0] to configure the Watchdog-Fail threshold WD_RST_TH[2:0] to configure the Watchdog-Reset threshold WD_QA_FDBK[1:0] to configure the settings for the reference answer-generation WD_QA_LFSR[1:0] to configure the settings for the question-generation WD_QUESTION_SEED[3:0] to configure the starting-point for the 1st question-generation The device keeps the above register bit values configured by the MCU as long as the device is powered. The MCU can configure the time interval of the Long Window (tLONG_WINDOW) with the WD_LONGWIN[7:0] bits. The WD_LONGWIN[7:0] bits are defined as: 0x00: 80 ms 0x01 - 0x40: 125 ms to 8 sec, in 125-ms steps 0x41 - 0xFF: 12 sec to 772 sec, in 4-sec steps Use #GUID-349299FD-F71B-4E28-A307-921903D70A3E/SLVSE828888 and #GUID-349299FD-F71B-4E28-A307-921903D70A3E/SLVSE822625 to calculate the minimum and maximum values for the Long Window (tLONG_WINDOW) time interval when WD_LONGWIN[7:0] > 0x00: tLONG_WINDOW_MIN = WD_LONGWIN[7:0] × 0.95 tLONG_WINDOW_MAX = WD_LONGWIN[7:0] × 1.05 If the MCU software changes the duration of the Long-Window to an interval shorter than the time in which the watchdog has been in the Long-Window, the time-out function of the Long-Window does no longer operate. When the MCU clears bit WD_EN, the watchdog goes out of the Long Window and disables the watchdog. When the watchdog is deactivated in this way, the MCU can set bit WD_EN back to ‘1’ to enable the watchdog again, and the MCU can control the ENABLE_DRV bit when no other error-flags are set. The MCU must clear bit WD_PWRHOLD before setting bit WD_EN back to ‘1’ to start the watchdog in Long Window. The watchdog locks the following configuration register bits when it goes out of the Long Window and starts the first watchdog sequence: WD_WIN1[6:0] WD_WIN2[6:0] WD_LONGWIN[7:0] WD_MODE_SELECT WD_QA_FDBK[1:0], WD_QA_LFSR[1:0] and WD_QUESTION_SEED[3:0] WD_RST_EN, WD_EN, WD_FAIL_TH[2:0] and WD_RST_TH[2:0] MCU to Watchdog Synchronization In order to go out of the Long Window and start the first watchdog sequence, the MCU must do the following before elapse of the Long Window time interval: Clear bits WD_PWRHOLD (more detail in ) Apply a pulse signal with a minimum pulse-width tWD_pulse on the pre-assigned GPIO pin in the case the watchdog is configured for Trigger mode, or Write four times to WD_ANSWER[7:0] in the case the watchdog is configured for Q&A mode When the MCU fails to get the watchdog out of the Long Window before the configured Long Window time interval (tLONG_WINDOW) elapses, the device goes through a warm reset, and sets the WD_LONGWIN_TIMEOUT_INT. This bit latched until the MCU writes a ‘1’ to clear it. Watchdog Disable Function The watchdog in the TPS6593-Q1 device has a Watchdog Disable function to prevent an unwanted MCU reset in case the MCU is un-programmed or needs to be reprogrammed. In order to activate this Watchdog Disable function for an un-programmed MCU, DISABLE_WDOG pin must be asserted to a logic-high level for a time-interval longer than tWD_DIS prior to the moment the device releases the nRSTOUT pin. If the Watchdog Disable function is activated in this way, the device sets bit WD_PWRHOLD to keep the watchdog in the Long Window. The watchdog stays in the Long Window until the MCU clears the WD_PWRHOLD bit. In case the MCU needs to be reprogrammed while the watchdog monitors the correct operation of the MCU, the MCU can set bit WD_RETURN_LONGWIN to put the watchdog back in the Long Window. When the MCU set this bit, the watchdog returns to the Long Window after the current Watchdog Sequence completes. In order to make the watchdog stay in the Long Window as long as needed the MCU can either re-configure the Long Window (tLONG_WINDOW) time interval, or set the WD_PWRHOLD bit. Once the MCU starts the first watchdog sequence (as described in ), the MCU must clear bit WD_RETURN_LONGWIN before the end of the first watchdog sequence in order to continue the watchdog sequence operation. Watchdog Sequence Once the watchdog is out of the Long Window, each watchdog sequence starts with a Window-1 followed by a Window-2. The watchdog ends the current sequence and after one 20-MHz system clock cycle starts a next sequence when one of the events below occurs: The configured Window-2 time period elapses The watchdog detects a pulse signal with a minimum pulse-width tWD_pulse on the pre-assigned GPIO pin if the watchdog is used in Trigger mode The watchdog detects four times a write access to WD_ANSWER[7:0] in case the watchdog is used in Q&A mode The MCU can configure the time periods of the Window-1 (tWINDOW1) and Window-2 (tWINDOW2) with the bits WD_WIN1[6:0] and WD_WIN2[6:0] respectively, before starting the sequence. Use #GUID-601CEE28-A758-488E-9836-FEEC1D7197D3/SLVSE822895 and #GUID-601CEE28-A758-488E-9836-FEEC1D7197D3/SLVSE828785 to calculate the minimum and maximum values for the tWINDOW1 time interval. tWINDOW1_MIN = (WD_WIN1[6:0] + 1) × 0.55 × 0.95 ms tWINDOW1_MAX = (WD_WIN1[6:0] + 1) × 0.55 × 1.05 ms Use #GUID-601CEE28-A758-488E-9836-FEEC1D7197D3/SLVSE824341 and #GUID-601CEE28-A758-488E-9836-FEEC1D7197D3/SLVSE822158 to calculate the minimum and maximum values for the tWINDOW-2 time interval. tWINDOW2_MIN = (WD_WIN2[6:0] + 1) × 0.55 × 0.95 ms tWINDOW2_MAX = (WD_WIN2[6:0] + 1) × 0.55 × 1.05 ms Watchdog Trigger Mode When the TPS6593-Q1 device is configured to use the Watchdog Trigger Mode, the watchdog receives the watchdog-triggers from the MCU on the pre-assigned GPIO pin . A rising edge on this , followed by a stable logic-high level on that pin for more than the maximum pulse time, tWD_pulse(max), is a watchdog-trigger. The watchdog uses a deglitch filter with a tWD_pulse filter time and the internal 20-MHz system clock to create the internally-generated trigger pulse from the watchdog-trigger on the pre-assigned GPIO pin . The watchdog detects a good event when the watchdog-trigger comes in Window-2. The rising edge of the watchdog-trigger on the pre-assigned GPIO pin must occur for at least the tWD_pulse time before the end of Window-2 to generate such a good event. The watchdog detects a bad event when one of the following events occurs: The watchdog-trigger comes in Window-1. The rising edge of the watchdog-trigger on the pre-assigned GPIO pin must occur for at least the tWD_pulse time before the end of Window-1 to generate such a bad event. In case of this bad event, the device sets bits WD_TRIG_EARLY and WD_BAD_EVENT. No watchdog-trigger comes in Window-2. In case of this bad event (also referred to as time-out event), the device sets bits WD_TIMEOUT and WD_BAD_EVENT. Please consider that the minimum WD-pulse duration needs to meet the maximum deglitch time tWD_pulse (max). The status bit WD_BAD_EVENT is read-only. The watchdog clears the WD_BAD_EVENT status bit at the end of the watchdog-sequence. WatchDog Flow Chart and Timing Diagrams in Trigger Mode shows the flow-chart of the watchdog in Trigger mode.

Watchdog Question-Answer Mode A 20220110 Added Section:Watchdog Question-Answer Modeyes When the TPS6593-Q1 device is configured to use the Watchdog Question Answer mode, the watchdog requires specific messages from the MCU in specific time intervals to detect correct operation of the MCU. The device provides a question for the MCU in WD_QUESTION[3:0] during operation. The MCU performs a fixed series of arithmetic operations on this question to calculate the required 32-bit answer. This answer is split into four answer bytes: Answer-3, Answer-2, Answer-1, and Answer-0. The MCU writes these answer bytes one byte at a time into WD_ANSWER[7:0] from the SPI or the dedicated I2C2 interface, mapped to GPIO1 and GPIO2 pins. A good event occurs when the MCU sends the correct answer-bytes calculated for the current question in the correct watchdog window and in the correct sequence. A bad event occurs when one of the events that follows occur: The MCU sends the correct answer-bytes, but not in the correct watchdog window. The MCU sends incorrect answer-bytes. The MCU returns correct answer-bytes, but in the incorrect sequence. If the MCU stops providing answer-bytes for the duration of the watchdog time-period, the watchdog detects a time-out event. This time-out event sets the WD_TIMEOUT status bit, increments the WD_FAIL_CNT[3:0] counter, and starts a new watchdog sequence. Watchdog Q&A Related Definitions A question and answer are defined as follows: Question A question is a 4-bit word (see ). The watchdog provides the question to the MCU when the MCU reads the WD_QUESTION[3:0] bits. The MCU can request each new question at the start of the watchdog sequence, but this is not required to calculate the answer. The MCU can also have a software implementation that generates the question according the circuit shown in . Nevertheless, the answer and therefore the answer-bytes are always based on the question generated inside the watchdog of the device. So, if the MCU generates an incorrect question and gives answer-bytes calculated from this incorrect question, the watchdog detects a bad event Answer An answer is a 32-bit word that is split into four answer bytes: Answer-3, Answer-2, Answer-1, and Answer-0. The watchdog receives an answer-byte when the MCU writes to the WD_ANSWER[7:0] bits. For each question, the watchdog requires four correct answer-bytes from the MCU in the correct timing and order (Answer-3, Answer-2, and Answer-1 in Window 1 in the correct sequence, and Answer-0 in Window 2) to detect a good event. The watchdog sequence in Q&A mode ends after the MCU writes the fourth answer byte (Answer-0), or after a time-out event when the Window-2 time-interval elapses. Watchdog Sequence in Q&A Mode The register WD_QUESTION_ANSW_CNT has following bits: Bit 6: Reserved Bit 5-4: WD_ANSW_CNT. These bits give the number for the next expected answer-byte Bit 3-0: WD_QUESTION. These bits give the value of the current generated question (1) For the question generation, the MCU is not required to read the question. The MCU can give correct answer-bytes Answer-3, Answer-2, Answer-1 as soon as Window-1 starts. The next watchdog sequence always starts in 1 system clock cycle after the watchdog receives the final Answer-0. (2) The MCU can put other I2C or SPI commands in-between the write-commands to WD_ANSWER[7:0] (even re-requesting the question). The insertion of other commands in-between the write-commands to WD_ANSWER[7:0] has no influence on the detection of a good event, as long as the three correct answer-bytes in Window-1 are in the correct sequence, and the fourth correct answer-byte is provided before the configured Window-2 time-interval elapses. Question Generation The watchdog uses a 4-bit question counter (QST_CNT[3:0] bits in ), and a 4-bit Markov chain to generate a 4-bit question. The MCU can read this question in the WD_QUESTION[3:0] bits. The watchdog generates a new question when the question counter increments, which only occurs when the watchdog detects a good event. The watchdog does not generate a new question when it detects a bad event or a time-out event. The question-counter provides a clock pulse to the Markov chain when it transitions from 4’b1111 to 4’b0000. The question counter and the Markov chain are set to the default value of 4’b0000 when the watchdog goes out of the Long Window. The Question-Generator is only re-initialized (starting with question 0000) at device power-up. In following situations, the MCU software needs to read the current question in order to synchronize with the Question-Generator: After MCU re-boot from a warm-reset After MCU software sets bit WD_RETURN_LONGWIN=1 to put the Watchdog back into Long Window After MCU wrote WD_EN=0, then reenable Watchdog again with WD_EN=1 shows the logic combination for the WD_QUESTION[3:0] generation. shows how the logic combination of the question-counter with the WD_ANSW_CNT[1:0] status bits generates the reference answer-bytes. Watchdog Question Generation (1) If the current value for bits (x1, x2, x3, x4) is 4'b0000, the next value for these bits (x1, x2, x3, x4) is 4'b0001, and all further question generation begins from this value. Watchdog Reference Answer Calculation Answer Comparison The 2-bit, watchdog-answer counter, WD_ANSW_CNT[1:0], counts the number of received answer-bytes and controls the generation of the reference answer-byte as shown in . At the start of each watchdog sequence, the default value of the WD_ANSW_CNT[1:0] counter is 2’b11 to indicate that the watchdog expects the MCU to write the correct Answer-3 in WD_ANSWER[7:0]. The device sets the WD_ANSW_ERR status bit as soon as one answer byte is not correct. The device clears this status bit only if the MCU writes a ‘1’ to this bit. Sequence of the 2-bit Watchdog Answer Counter The sequence of the 2-bit, watchdog answer-counter is as follows for each counter value: WD_ANSW_CNT[1:0] = 2‘b11: The watchdog calculates the reference Answer-3. A write access occurs. The MCU writes the Answer-3 byte in WD_ANSWER[7:0]. The watchdog compares the reference Answer-3 with the Answer-3 byte in WD_ANSWER[7:0]. The watchdog decrements the WD_ANSW_CNT[1:0] bits to 2b‘10 and sets the WD_ANSW_ERR status bit to 1 if the Answer-3 byte was incorrect. WD_ANSW_CNT[1:0] = 2b‘10: The watchdog calculates the reference Answer-2. A write access occurs. The MCU writes the Answer-2 byte in WD_ANSWER[7:0]. The watchdog compares the reference Answer-2 with the Answer-2 byte in WD_ANSWER[7:0].. The watchdog decrements the WD_ANSW_CNT[1:0] bits to 2b‘01 and sets the WD_ANSW_ERR status bit to 1 if the Answer-2 byte was incorrect. WD_ANSW_CNT[1:0] = 2b‘01: The watchdog calculates the reference Answer-1. A write access occurs. The MCU writes the Answer-1 byte in WD_ANSWER[7:0]. The watchdog compares the reference Answer-1 with the Answer-1 byte in WD_ANSWER[7:0].. The watchdog decrements the WD_ANSW_CNT[1:0] bits to 2b‘00 and sets the WD_ANSW_ERR status bit to 1 if the Answer-1 byte was incorrect. WD_ANSW_CNT[1:0] = 2b‘00: The watchdog calculates the reference Answer-0. A write access occurs. The MCU writes the Answer-0 byte in WD_ANSWER[7:0]. The watchdog compares the reference Answer-0 with the Answer-0 byte in WD_ANSWER[7:0]. The watchdog sets the WD_ANSW_ERR status bit to 1 if the Answer-0 byte was incorrect. The watchdog starts a new watchdog sequence and sets the WD_ANSW_CNT[1:0] to 2‘b11’. The MCU needs to clear the bit by writing a '1' to the WD_ANSW_ERR bit.

After such a good event, following events occur: The WD_FAIL_CNT[2:0] counter decrements by one at the end of the watchdog-sequence. The question-counter increments by one and the watchdog generates a new question. A bad event occurs when all answer-bytes are correct in value but not in correct timing. After such a bad event, following events occur: The WD_SEQ_ERR and WD_BAD_EVENT status bits are set if Window-1 time-interval elapses before watchdog has received Answer-3, Answer-2 and Answer-1. The WD_ANSW_EARLY and WD_BAD_EVENT status bits are set if watchdog receives all four answers in Window-1. The WD_FAIL_CNT[2:0] counter increments by one at the end of the watchdog-sequence. The question-counter does not change, and hence the watchdog does not generate a new question. A bad event occurs when one or more of the answer-bytes are not correct in value but in correct timing. After such a bad event, following events occur: The WD_ANSW_ERR and WD_BAD_EVENT status bits are set as soon as the watchdog detects an incorrect answer-byte. The WD_FAIL_CNT[2:0] counter increments by one at the end of the watchdog-sequence. The question-counter does not change, and hence the watchdog does not generate a new question. A bad event occurs when one or more of the answer-bytes are not correct in value and not in correct timing. After such a bad event, following events occur: The WD_ANSW_ERR and WD_BAD_EVENT status bits are set as soon as the watchdog detects an incorrect answer-byte. The WD_SEQ_ERR and WD_BAD_EVENT status bits are set if Window-1 time-interval elapses before watchdog has received Answer-3, Answer-2 and Answer-1. The WD_ANSW_EARLY and WD_BAD_EVENT status bits are set if watchdog receives all four answer-bytes in Window-1. The WD_FAIL_CNT[2:0] counter increments by one at the end of the watchdog-sequence. The question-counter does not change, and hence the watchdog does not generate a new question. A time-out event occurs when the device receives less than 4 answer-bytes before Window-2 time-interval elapses. After a time-out event occurs, following events occur: WD_SEQ_ERR and WD_BAD_EVENT status bits are set if Window-1 time-interval elapses before watchdog has received Answer-3, Answer-2 and Answer-1. The WD_TIMEOUT and WD_BAD_EVENT status bits are set at the end of the watchdog-sequence. The WD_FAIL_CNT[2:0] counter increments by one at the end of the watchdog-sequence. The question-counter does not change, and hence the watchdog does not generate a new question. The status bit WD_BAD_EVENT is read-only. The watchdog clears the WD_BAD_EVENT status bit at the end of the watchdog-sequence. The status bits WD_SEQ_ERR, WD_ANSW_EARLY, and WD_TIMEOUT are latched until the MCU writes a ‘1’ to these bits. If one or more of these status bits are set, the watchdog can still detect a good event in the next watchdog-sequence. These status bits are read-only. The watchdog clears the WD_BAD_EVENT status bit at the end of the watchdog-sequence. shows the flow-chart of the watchdog in Q&A mode.

Signal Monitor (ESM)yes The TPS6593-Q1 device has two error signal monitor (ESMs): one ESM_MCU to monitor the MCU error output signal at the nERR_MCU input pin, and one ESM_SoC to monitor the SoC error output signal at the nERR_SoC input pin. At device start-up, the ESM_MCU and ESM_SoC can be enabled or deactivated through configuration bits ESM_MCU_EN and ESM_SOC_EN. The values for these configuration bits are stored in the NVM memory of the device. To start the enabled ESM, the MCU sets the start bits ESM_MCU_START or ESM_SOC_START for the corresponding ESM through software after the system is powered up and the initial software configuration is completed. If the MCU clears a start bit, the ESM stops monitoring its input pin. The MCU can set the ENABLE_DRV bit only when the MCU has either started or deactivated the ESM. When the corresponding ESM is started, the following configuration registers are write protected and can only be read: Configuration registers write-protected by the ESM_MCU_START register bit: ESM_MCU_DELAY1_REG ESM_MCU_DELAY2_REG ESM_MCU_MODE_CFG ESM_MCU_HMAX_REG ESM_MCU_HMIN_REG ESM_MCU_LMAX_REG ESM_MCU_LMIN_REG Configuration registers write-protected by the ESM_SOC_START register bit: ESM_SOC_DELAY1_REG ESM_SOC_DELAY2_REG ESM_SOC_MODE_CFG ESM_SOC_HMAX_REG ESM_SOC_HMIN_REG ESM_SOC_LMAX_REG ESM_SOC_LMIN_REG The ESM uses a deglitch-filter with deglitch-time tdegl_ESMx to monitor its related input pin. The MCU can configure the ESM in two different modes that are defined as follows: Level Mode the ESM detects an ESM-error when the input pin remains low for a time equal to or longer than the deglitch-time tdegl_ESMx. To select this mode for the ESM_MCU, the MCU must clear bit ESM_MCU_MODE. To select this mode for the ESM_SoC, the MCU must clear bit ESM_SOC_MODE. See for further detail. PWM Mode the ESM monitors a PWM signal at its input pin. The ESM detects a bad-event when the frequency or duty cycle of the PWM input signal deviates from the expected signal. The ESM detects a good-event when the frequency and duty cycle of the PWM signal match with the expected signal for one signal period. The ESM has an error-counter (ESM_MCU_ERR_CNT[4:0] or ESM_SOC_ERR_CNT[4:0]), which increments with +2 after each bad-event, and decrements with -1 after each good-event. The ESM detects an ESM-error when the error-counter value is more than its related threshold value. To select this mode for the ESM_MCU, the MCU must set bit ESM_MCU_MODE. To select this mode for the ESM_SoC, the MCU must set bit ESM_SOC_MODE. See for further details. The MCU can configure each ESM as long as its related start bit is cleared to 0 (bit ESM_MCU_START or ESM_SOC_START). As soon as the MCU sets a start bit, the device sets a write-protection on the configuration registers of the related ESM except the related start bits ESM_MCU_START and ESM_SOC_START. ESM Error-Handling Procedure Each ESM has two of its own configurable delay-timers that are reset when the device clears the respective ESM_x_START bit. Below steps describe the procedure through which the ESM goes in case it detects an ESM-error: If the respective mask bit ESM_x_PIN_MASK=0, the device sets interrupt bit ESM_MCU_PIN_INT or ESM_SOC_PIN_INT, and pulls the nINT pin low. The ESM starts the delay-1 timer (configurable through related ESM_MCU_DELAY1[7:0] or ESM_SOC_DELAY1[7:0] bits). If the ESM-error is no longer present and MCU has cleared the related interrupt bit ESM_MCU_PIN_INT or ESM_SOC_PIN_INT before the delay-1 timer elapses, the device releases the nINTpin, the ESM resets the delay-1 and delay-2 timers and continues to monitor its input pin. If the ESM-error is still present, or if MCU has not cleared the related interrupt bit ESM_MCU_PIN_INT or ESM_SOC_PIN_INT, and the delay-1 timer elapses, then the ESM clears the ENABLE_DRV bit if bit ESM_MCU_ENDRV=1 or if bit ESM_SOC_ENDRV=1. If the delay-2 timer (configurable through related ESM_MCU_DELAY2[7:0] or ESM_SOC_DELAY2[7:0] bits) is set to 0, then the ESM skips steps 6 of this list, and performs step 7. If the delay-2 timer is not set to 0, then: ESM starts the delay-2 timer, If ESM_MCU_FAIL_MASK = 0, the device sets interrupt bit ESM_MCU_FAIL_INT and pulls the nINT pin low and starts the delay-2 timer. If ESM_SOC_FAIL_MASK = 0, the device sets interrupt bit ESM_SOC_FAIL_INT, pulls the nINT pin low and starts the delay-2 timer. If the ESM-error is no longer present and the MCU has cleared the related interrupt bits listed below before the delay-2 timer elapses, the device releases the nINTpin, the ESM resets the delay-1 and delay-2 timers and continues to monitor its input pin: ESM_MCU_PIN_INT (and ESM_MCU_FAIL_INT if set in step 6), or ESM_SOC_PIN_INT (and ESM_SOC_FAIL_INT if set in step 6) If the ESM-error is still present, or if MCU has not cleared the related interrupt bits ESM_MCU_PIN_INT and ESM_MCU_FAIL_INT , or ESM_SOC_PIN_INT and ESM_SOC_FAIL_INT, and the delay-2 timer elapses, then : For ESM_MCU, the device: clears the ESM_MCU_START BIT sets interrupt bits ESM_MCU_FAIL_INT and ESM_MCU_RST_INT, which the device handles as an ESM_MCU_RST trigger for FSM, described in Summary of Interrupt Signals After this trigger handling completes, the device re-initializes the ESM_MCU For ESM_SoC, the device: clears the ESM_SOC_START bit sets interrupt bits ESM_SOC_FAIL_INT and ESM_SOC_RST_INT, which the device handles as an ESM_SOC_RST trigger for FSM, described in Summary of Interrupt Signals After this trigger handling completes, the device re-initializes the ESM_SoC ESM_MCU_DELAY1[7:0] and ESM_SOC_DELAY1[7:0] set the delay-1 time-interval (tDELAY-1) for the related ESM_MCU or ESM_SoC. Use #GUID-DF6532B4-B17E-4C92-B12D-2D4021966C59/SLVSE82707 and #GUID-DF6532B4-B17E-4C92-B12D-2D4021966C59/SLVSE827308 to calculate the worst-case values for the tDELAY-1: Min. tDELAY-1 = (ESM_x_DELAY1[7:0] × 2.048 ms) × 0.95 Max. tDELAY-1 = (ESM _x_DELAY1[7:0] × 2.048 ms) × 1.05 , in which x stands for either MCU or SoC.

Level Mode In Level Mode, after MCU has set the start bit (bit ESM_MCU_START or bit ESM_SOC_START), the ESM monitors its nERR_MCU or nERR_SoC input pin. Each ESM detects an ESM-error when the voltage level on its input pin remains low for a time equal or longer than the deglitch-time tdegl_ESMx. When an ESM_x detects an ESM-error, it starts the ESM Error-Handling procedure as described in . The Error-Handling Procedure is stopped if, before elapse of the delay-1 or delay-2 interval, the voltage level on the input pin remains high for a time equal or longer than the deglitch-time tdegl_ESMx and the MCU clears all corresponding interrupt bits. If the ESM-error persists such that the configured delay-1 and delay-2 times elapse, the ESM sends a ESM_x_RST trigger to the PFSM and the device clear the ESM_x_START bit. After the PFSM completes the handling of the ESM_x_RST trigger, the device re-initializes the ESM. For a complete overview on how the ESM works in Level Mode, please refer to the flow-chart in .

If the input signal remains low after exceeding the maximum low-pulse time-threshold (tLOW_MAX_TH), the ESM detects a bad event and the low-pulse duration counter reinitializes. Each time the signal further exceeds the maximum threshold, the ESM detects a bad event. On the next rising edge on the input signal, the ESM starts the high-pulse time-duration monitoring After a rising edge, the ESM starts monitoring the high-pulse time-duration. If the input signal remains high after exceeding the maximum high-pulse time-threshold (tHIGH_MAX_TH), the ESM detects a bad event and the high-pulse duration counter reinitializes. Each time the signal further exceeds the maximum threshold, the ESM detects a bad event. On the next falling edge on the input signal, the ESM starts the low-pulse time-duration monitoring. In addition, each ESM detects a bad-event in PWM mode if one of the events that follow occurs on the deglitched signal of the related input pin nERR_MCU or nERR_SoC: A high-pulse time-duration that is longer than the maximum high-pulse time-threshold (tHIGH_MAX_TH) that is configured in corresponding register bits ESM_MCU_HMAX[7:0] or ESM_SOC_HMAX[7:0].

Please note that when setting up the minimum and the maximum low-pulse or high-pulse time-thresholds need to be configured such that clock tolerances from the TPS6593-Q1 and from the processor are incorporated. #GUID-8AB05BFB-234E-4174-9368-666CD9A02C95/SLVSE826982, #GUID-8AB05BFB-234E-4174-9368-666CD9A02C95/SLVSE823780, #GUID-8AB05BFB-234E-4174-9368-666CD9A02C95/SLVSE827462, and #GUID-8AB05BFB-234E-4174-9368-666CD9A02C95/SLVSE825152 are a guideline on how to incorporate these clock-tolerances: ESM_x_HMIN[7:0] < 0.5 × (ESM_x_HMAX[7:0] + ESM_x_HMIN[7:0]) × 0.95 × (1 - MCU/SoC clock tolerance) ESM_x_HMAX[7:0] > 0.5 × (ESM_x_HMAX[7:0] + ESM_x_HMIN[7:0]) × 1.05 × (1 + MCU/SoC clock tolerance) ESM_x_LMIN[7:0] < 0.5 × (ESM_x_LMAX[7:0] + ESM_x_LMIN[7:0]) × 0.95 × (1 - MCU/SoC clock tolerance) ESM_x_LMAX[7:0] > 0.5 × (ESM_x_LMAX[7:0] + ESM_x_LMIN[7:0]) × 1.05 × (1 + MCU/SoC clock tolerance) , in which x stands for either MCU or SoC. ESM Error-Counter If an ESM detects a bad-event, it increments its related error-counter (bits ESM_MCU_ERR_CNT[4:0] or bits ESM_SOC_ERR_CNT[4:0]) by 2. If an ESM detects a good-event, it decrements its related error-counter (bits ESM_MCU_ERR_CNT[4:0] or bits ESM_SOC_ERR_CNT[4:0]) by 1. The device clears each ESM error counter when ESM_x_START=0. Furthermore, the device clears the error-counter ESM_SOC_ERR[4:0] when it resets the SoC. Each ESM error-counter has a related threshold (bits ESM_MCU_ERR_CNT_TH[3:0] or bits ESM_SOC_ERR_CNT_TH[3:0]) that the MCU can configure if the related ESM_x_START bit is 0. If the ESM error-counter value is above its configured threshold, the related ESM has detected a so-called ESM-error and starts the Error-Handling Procedure as described in . If the ESM error-counter reached a value equal or less its configured threshold before the elapse of the configured delay-1 or delay-2 intervals and the MCU software clears all ESM related interrupt bits, the ESM-error is no longer present and the ESM stops the Error-Handling Procedure as described in . If the ESM-error persists such that the configured delay-1 and delay-2 times elapse, the ESM sends a ESM_x_RST trigger to the PFSM and the device clears the ESM_x_START bit. After the PFSM completes the handling of the ESM_x_RST trigger, the device re-initializes the related ESM. ESM Start-Up in PWM Mode After the MCU has set the start bit of an ESM (bit ESM_MCU_START or bit ESM_SOC_START), there are two possible scenarios: The deglitched signal of the monitored input pin has a low level at the moment the MCU sets the start bit. In this scenario, the related ESM starts the following procedure: Start a timer with a time-length according the value configured in corresponding ESM_MCU_LMAX[7:0] or ESM_SOC_LMAX[7:0]. Wait for a first rising edge on its deglitched input signal. If the rising edge comes before the configured time-length elapses, the ESM skips the next step and starts to monitor the high-pulse duration time. Hereafter, the ESM detects good-events or bad-events as described in . shows an example this scenario as Case Number 1. If the configured time-length (configured in corresponding ESM_MCU_LMAX[7:0] or ESM_SOC_LMAX[7:0]) elapses, the ESM detects a bad-event and increments the related error-counter with +2. Hereafter, the ESM detects good-events or bad-events as described in . shows an example this scenario as Case Number 3. If the ESM error-counter value is above its configured threshold, the related ESM has detected a so-called ESM-error and starts the Error-Handling Procedure as described in . During this Error-Handling Procedure, the ESM continues to monitor its related input pin, and updates the error-counter accordingly when it detects good-events or bad-events, until the Error-Handling Procedure reaches the step in which the ESM sends an ESM_x_RST trigger to the PFSM, which, depending on the PFSM configuration, resets the MCU or SoC. shows a scenario in which the device resets the MCU or SoC as Case Number 4. If the ESM error-counter reaches a value equal or less its configured threshold before the elapse of the configured delay-1 or delay-2 time-intervals and the MCU software clears all ESM related interrupt bits, the ESM-error is no longer present and the ESM stops the Error-Handling Procedure as described in . The deglitched signal monitored input pin has a high level at the moment the MCU sets the start bit. In this scenario, the related ESM starts the following procedure: Start a timer with a time-length according the value configured in corresponding ESM_MCU_HMAX[7:0] or ESM_SOC_HMAX[7:0]. Wait for a first falling edge on its deglitched input signal. If the falling edge comes before the configured time-length elapses, the ESM skips the next step and starts to monitor the low-pulse duration time. Hereafter, the ESM detects good-events or bad-events as described in . shows an example this scenario as Case Number 2. If the configured time-length (configured in corresponding ESM_MCU_HMAX[7:0] or ESM_SOC_HMAX[7:0]) elapses, the ESM detects a bad-event and increments the related error-counter with +2. Hereafter, the ESM detects good-events or bad-events as described in . If the ESM error-counter value is above its configured threshold, the related ESM has detected a so-called ESM-error and starts the Error-Handling Procedure as described in .

If the ESM error-counter reaches a value equal or less its configured threshold before the elapse of the configured delay-1 or delay-2 time-intervals and the MCU software clears all ESM related interrupt bits, the ESM-error is no longer present and the ESM stops the Error-Handling Procedure as described in .

Afterwards the ESM Detects Bad Events, and the PWM Signal Recovers Too Late which Leads to an ESM_x Reset Trigger to the PFSM (The _x stand for _MCU or _SoC) Device Functional Modes Device State Machine The TPS6593-Q1 device integrates a finite state machine (FSM) engine that manages the state of the device during operating state transitions. The device supports NVM-configurable mission states with configurable input triggers for transitions between states. Any resources, including the 5 BUCK regulators, 4 LDO regulators, and all of the digital IO pins including the 11 GPIO pins on the device can be controlled during power sequencing. When a resource is not controlled or configured through a power sequence, the resource is left in the default state as pre-configured by the NVM. Each resource can be pre-configured through the NVM configuration, or re-configured through register bits. Therefore, the user can statically control the resource through the control interfaces (I2C or SPI), or the FSM can automatically control the resource during state sequences. The FSM is powered by an internal LDO that is automatically enabled when VCCA supply is available to the device. Ensuring that the VCCA supply is the first supply available to the device is important to ensure proper operation of all the power resources as well as the control interface and device IOs. There are three parts of the FSM that control the operational modes of the TPS6593-Q1 device: Fixed Device Power Finite State Machine (FFSM) Pre-configurable Finite State Machine (PFSM) for Mission States (ACTIVE, MCU_ONLY, S2R, DEEP_SLEEP) Error Handling Operations The PFSM provides configurable rail and voltage monitoring sequencing utilizing instructions in configuration memory. This flexibility enables customers to alter power-up sequences on a platform basis. The FFSM handles the majority of fixed functionality that is internally mandated and common to all platforms. Fixed Device Power FSM The Fixed Device Power portion of the FSM engine manages the power up of the device before the power rails are fully enabled and ready to power external loadings, and the power down of the device when in the event of insufficient power supply or device or system error conditions. While the device is in one of the Hardware Device Powers states, the ENABLE_DRV bit remains low. The definitions and transition triggers of the Device Power States are fixed and cannot be reconfigured. Following are the definitions of the Device Power states: NO SUPPLY The device is not powered by a valid energy source on the system power rail. The device is completely powered off. BACKUP (RTC backup battery) The device is not powered by a valid supply on the system power rail (VCCA < VCCA_UVLO); a backup power source, however, is present and is within the operating range of the LDOVRTC. The RTC clock counter remains active in this state if it has been previously activated by appropriate register enable bit. The calendar function of the RTC block is activated, but not accessible in this state. Customer has the option to enable the shelf mode by disconnecting the VCCA supply completely, even while the backup battery is connected to the VBACKUP pin. The shelf mode forces the device to skip the BACKUP state and enters the NO SUPPLY state under VCCA_UVLO condition to reduce current draining from the backup battery. LP_STANDBY The device can enter this state from a mission state after receiving a valid OFF request or an I2C trigger, and the LP_STANDBY_SEL= 1. When the device is in this state, the RTC clock counter and the RTC Alarm or Timer Wake-up functions are active if they have been previously activated by appropriate register enable bit. Low Power Wake-up input monitor in the LDOVRTC domain (LP_WKUP secondary function through GPIO3 or GPIO4) and the on request monitors are also enabled in this state. When a logic level transition from high-to-low or low-to-high with a minimum pulse length of tLP_WKUP is detected on the assigned LP_WKUP pin, or if the device detects a valid on-request or a wake-up signal from the RTC block, the device proceeds to power up the device and reach the default mission state. More details regarding the LP_WAKE function can be found in . INIT The device is powered by a valid supply on the system power rail (VCCA ≥ VCCA_UV). If the device was previously in LP_STANDBY state, it has received an external wake-up signal at the LP_WKUP1/2 pins, the RTC alarm or timer wake-up signal, or an On Request from the nPWRON/ENABLE pin. Device digital and monitor circuits are powered up. The PMIC reads its internal NVM memory in this state and configures default values to registers, IO configuration and FSM accordingly. BOOT BIST The device is running the built-in self-test routine that includesThe ABIST on the voltage monitor circuits for the BUCK regulators, the LDO regulators is performed after the start-up of these regulators. The ABIST on the VMON1 and VMON2 is performed after these voltage monitors are enabled. See Voltage Monitors. An option is available to shorten the device power up time from the NO_SUPPLY state by setting the NVM bit FAST_BOOT_BIST = '1' to skip the LBIST. Software can also set the FAST_BIST = '1' to skip LBIST after the device wakes up from the LP STANDBY state. When the device arrives at this state from the SAFE_RECOVERY state, LBIST is automatically skipped if it has not previously failed. If LBIST failed, but passed after multiple re-tries before exceeding the recovery counter limit, the device powers up normally. The following NVM bits are pre-configured options to enable or disable parts of the CRC tests if further sequence time reduction is required (please refer to the user's guide of the orderable part number): REG_CRC_EN = '0': disables the register map and SRAM CRC check Note: the BIST tests are executed as parallel processes, and the longest process determines the total BIST duration the ABIST on the voltage monitor circuits of the BUCKx regulator, LDOn regulators, VMON1 and VMON2 is performed individually after these voltage monitors are enabled. See Voltage Monitors) RUNTIME BIST A request was received from the MCU to exercise a run-time built-in self-test (RUNTIME_BIST) on the device. No rails are modified and all external signals, including all I2C or SPI interface communications, are ignored during the RUNTIME_ BIST. During the RUNTIME_BIST, the device performs the same self-test routines as listed for the BOOT_BIST state. Furthermore, during RUNTIME_BIST the device performs the ABIST routine on all enabled voltage monitor circuits. If the device passed BIST, it resumes the previous operation. If the device failed BIST, it shuts down all of the regulator outputs and proceed to the SAFE RECOVERY state. In order to avoid a register CRC error, all register writes must be avoided after the request for the BIST operation until the device pulls the nINT pin low to indicate the completion of BIST. The results of the RUNTIME_BIST are indicated by the BIST_PASS_INT or the BIST_FAIL_INT interrupt bits.After completion of the RUNTIME_BIST, the LDOx_UV detections are masked for a time-interval equal to the configured LDOx ramp-up time (25 mV/μs or 3 mV/μs according configuration bit LDOx_SLOW_RAMP). The actual LDOx output voltages are not affected by this masking of the LDOx_UV detections. SAFE RECOVERY The device meets the qualified error condition for immediate or ordered shutdown request. If the error is recovered within the recovery time interval or meets the restart condition, the device increments the recovery counter, and returns to INIT state if the recovery counter value does not exceed the threshold value. Until a supply power cycle occurs, the device stays in the SAFE RECOVERY state if one of the following conditions occur: the recovery counter exceeds the threshold value the die temperature cannot be reduced to less than TWARN level VCCA stays above OVP threshold When multiple system conditions occur simultaneously that demand power state arbitration, the device goes to the higher priority state according to the following priority order: NO SUPPLY BACKUP SAFE_RECOVERY LP_STANDBY MISSION STATES shows the power transition states of the FSM engine. State Diagram for Device Power States Register Resets and NVM Read at INIT State Several registers inside the TPS6593-Q1 have pre-configured default values that are stored in the NVM of the TPS6593-Q1. These registers are referred to as NVM pre-configured registers. When the device transitions from the LP_STANDBY or the SAFE_RECOVERY to the INIT state, based on FIRST_STARTUP_DONE bit, the registers are reset and the NVM is read. When the FIRST_STARTUP_DONE is '0', registers which are not in the RTC domain are reset, and all of the NVM pre-configured registers including the ones in the RTC domain, are loaded from the NVM. When the FIRST_STARTUP_DONE bit is set to '1', typically after the initial power up from a supply power cycle, the registers in the RTC domain are not reset, and the NVM pre-configured registers in the RTC domain are not re-loaded from the NVM. Setting the FIRST_STARTUP_DONE bit prevents the control and status bits stored in the RTC domain registers from being over written. Register resets and NVM read at INIT state FIRST _STARTUP_DONE NVM pre-configured registers in RTC Domain Registers without NVM pre-configuration in RTC Domain Other NVM pre-configured registers Registers without NVM pre-configuration 0 Defaults read from NVM No changes Reset and defaults read from NVM Reset 1 No changes No changes Reset and defaults read from NVM Reset Below are the NVM pre-configured register bits in the RTC domain: GPIO3_CONF and GPIO4_CONF registers, except the GPIOn_DEGLITCH_EN bits GPIO3_RISE_MASK, GPIO3_FALL_MASK, GPIO4_RISE_MASK, and GPIO4_FALL_MASK bits NPWRON_CONF register except ENALBE_DEGLITCH_EN and NRSTOUT_OD bits FSD_MASK, ENABLE_MASK, NPWRON, START_MASK, and NPWRON_LONG_MASK bits STARTUP_DEST, FAST_BIST, LP_STANDBY_SEL, XTAL_SEL, and XTAL_EN bits PFSM_DELAYn, and RTC_SPARE_n bits Below are the register bits without NVM pre-configuration in the RTC domain: FIRST_STARTUP_DONE bit SCRATCH_PAD_n bits All of RTC control and configuration registers Pre-Configurable Mission States When the device arrives at a mission state, all rail sequencing is controlled by the pre-configurable FSM engine (PFSM) through the configuration memory. The configuration memory allows configurations of the triggers and the operation states that together form the configurable sub state machine within the scope of mission states. This sub state machine can be used to control and sequence the different voltage outputs as well as any GPIO outputs that can be used as enable for external rails. When the device is in a mission state, it has the capacity to supply the processor and other platform modules depending on the power rail configuration. The definitions and transition triggers of the mission states are configurable through the NVM configuration. Unlike the user registers, the PFSM definition stored in the NVM cannot be modified during normal operation. When the PMIC determines that a transition to another operation state is necessary, it reads the configuration memory to determine what sequencing is needed for the state transition. Furthermore, the PFSM has four storage registers, further referred to as PFSM storage registers (R0-3). shows how the trigger signals for each state transition can come from a variety of interface or GPIO inputs, or potential error sources. shows how the device processes all of the possible error sources inside the PFSM engine, a hierarchical mask system is applied to filter out the common errors that can be handled by interrupt only, and categorize the other error sources as Severe Global Error, Moderate Global Error, and so forth. The filtered and categorized triggers are sent into the PFSM engine, that then determines the entry and exit condition for each configured mission state. Error Source Hierarchical Mask System shows an example of how the PFSM engine utilizes instructions to execute the configured device state and sequence transitions of the mission state-machine. provides the instruction set and usage description of each instruction in the following sections. describes how the instructions are stored in the NVM memory.

These two bits are then left shifted 2 bit-positions to give full byte value of 0bxx10xxxx, hence sets bits 5:4 to 0b10. REG_WRITE_VOUT_IMM Command Description: Write the target voltage of a specified regulator after a specified delay. This command is a spin-off of the REG_WRITE_IMM command with the intention to save instruction bits. Assembly command: REG_WRITE_VOUT_IMM [REGULATOR=]<Regulator ID> [SEL=]<VSEL> [VOUT=]<Vout> [DELAY=]<Delay>[BYPASS=]<BYPASS> 'REGULATOR=', ''SEL=', 'VOUT=', 'DELAY=' and 'BYPASS=' are syntax options. When included, the parameters can be in any order. Regulator ID = BUCK1, BUCK2, BUCK3, BUCK4 , BUCK5, LDO1, LDO2, LDO3, or LDO4. VSEL selects the BUCKn_VSET1 or BUCKn_VSET2 bits which the command writes to if Regulator ID is BUCK1-5. VSEL is defined as: '0': BUCKn_VSET1, '1': BUCKn_VSET2, '2': Currently Active BUCKn_VSET, '3': Currently Inactive BUCKn_VSET. If Regulator ID is LDO1-4, VSEL value is ignored. VOUT = output voltage in mV or V. Unit must be listed. DELAY = delay time in ns, µs, ms, or s. If no unit is entered, this field must be an integer value between 0-63, which becomes the threshold count for the counter running a step size specified in the register PFSM_DELAY_STEP. The delay value is rounded to the nearest achievable delay time based on the current step size. Current step size is based on the default NVM setting or a SET_DELAY value from a previous command in the same sequence.

If no unit is entered, this field must be an integer value between 0-63, which becomes the threshold count for the counter running a step size specified in the register PFSM_DELAY_STEP. Delay value is be rounded to the nearest achievable delay time based on the current step size. Current step size is based on the default NVM setting or a SET_DELAY value from a previous command in the same sequence. Assembler reports an error if the step size is too large or too small to meet the delay. Delay Mode must be one of the below options: MATCH_EN = 0 (Delay if VCTRL enable bit mismatches) MATCH_ALL = 1 (Delay if any VCTRL bits mismatch) ALWAYS = 2 (Delay always) Examples: REG_WRITE_VCTRL_IMM BUCK3 0x00 0xE0 100 µs — Sets BUCK3 to OFF (VCTRL bits = 0b00000) after 100 µs REG_WRITE_VCTRL_IMM REGULATOR=LDO1 VCTRL=0x09 MASK=0x36 DELAY=10 ms — Set LDO1_VMON and LDO1_EN to '1' after 10 ms REG_WRITE_MASK_SREG Command Description: Write the data from a PFSM storage register, except the masked bits, to the specified register address Assembly command: REG_WRITE_MASK_SREG [REG=]<PFSM Storage Register> [ADDR=]<Address> [MASK=]<Mask> 'REG=', 'ADDR=', and 'MASK=' are options. When included, the parameters can be in any order. PFSM Storage Register can be R0, R1, R2, or R3. Address and Mask can be in any literal integer format (decimal, hex, and so forth). Examples: REG_WRITE_MASK_SREG R2 0x22 0x00 — Write the content of PFSM storage register R2 to address 0x22 REG_WRITE_MASK_SREG REG=R0 ADDR=0x054 MASK=0xF0 — Write the lower 4 bits of PFSM storage register R0 to address 0x54 SREG_READ_REG Command Description: Write PFSM storage register (R0-3) with data from a specified address Assembly command: SREG_READ_REG [REG=]<PFSM Storage Register> [ADDR=]<Address> 'REG=' and 'ADDR=' are options. When included, the parameters can be in any order. PFSM Storage Register can be R0, R1, R2, or R3. Address can be in any literal integer format (decimal, hex, and so forth). Examples: SREG_READ_REG R2 0x15 — Read the content of address 0x15 and write the data to PFSM storage register R2 SREG_READ_REG ADDR=0x077 REG=R3 — Read the content of address 0x77 and write the data to PFSM storage register R3 SREG_WRITE_IMM Command Description: Write the specified data to the scratch register (R0-3) Assembly command: SREG_WRITE_IMM [REG=]<PFSM Storage Register> [DATA=]<Data> Data can be in any literal integer format (decimal, hex, and so forth). PFSM Storage Register can be R0, R1, R2, or R3. 'REG=' and 'DATA=' are options. When included, the parameters can be in any order. Examples: SREG_WRITE_IMM R2 0x15 — Write 0x15 to PFSM storage register R2 SREG_WRITE_IMM ADDR=0x077 REG=R3 — Read 0x77 to PFSM storage register R3 WAIT Command Description: Wait upon a condition of a given type. Execution is paused until the specified type of the condition is met or timed out Assembly command: WAIT [COND=]<Condition> [TYPE=]<Type> [TIMEOUT=]<Timeout> [DEST=]<Destination> Alternative assembly command: JUMP [DEST=]<Destination> 'COND=', 'TYPE=', 'TIMEOUT=', and 'DEST=' are options. When included, the parameters can be in any order. Condition are listed in #GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/SLVSEA74920. Examples: GPIO1, BUCK1_PG, I2C_1 Type = LOW, HIGH, RISE, or FALL Timeout = timeout value in ns, µs, ms, or s. If no unit is entered, this field must be an integer value between 0-63. Timeout value is be rounded to the nearest achievable time based on the current step size. Current step size is based on the default NVM setting or a SET_DELAY value from a previous command in the same sequence. Assembler reports an error if the step size is too large or too small to meet the delay. Destination = Label to jump to if when timeout occurs. Destination must be after the WAIT statement in memory. Memory space can be either '0' or '1'. '0' indicates the destination address is in the PFSM memory space. '1' indicates the destination address is external and represents a FSM state ID. When using the jump command, the PFSM performs an unconditional jump. The command is be compiled as "WAIT COND=63 TYPE=LOW TIMEOUT=0 DEST=<Destination>". Condition 63 is a hardcoded 1, so the condition is never satisfied and hence always times out. Therefore this command always jumps to the destination. Examples: WAIT GPIO4 RISE 1 s <Destination> 0 — Wait to execute the command at the specified SRAM address when a rise edge is detected at GPIO4, or after 1 second WAIT COND=BUCK1_PG TYPE=HIGH TIMEOUT=500 µs DEST=<mcu2act_seq> — Wait to execute the commands at <mcu2act_seq> address as soon as BUCK1 output is within power-good range, or after 500 µs WAIT Command Conditions COND_SEL Condition Name COND_SEL Condition Name COND_SEL Condition Name COND_SEL Condition Name 0 GPIO1#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 16 LDO1_PG 32 I2C_0#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 48 LP_STANDBY_SEL 1 GPIO2#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 17 LDO2_PG 33 I2C_1#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 49 N/A 2 GPIO3#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 18 LDO3_PG 34 I2C_2#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 50 N/A 3 GPIO4#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 19 LDO4_PG 35 I2C_3#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 51 N/A 4 GPIO5#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 20 PGOOD 36 I2C_4#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 52 N/A 5 GPIO6#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 21 TWARN_EVENT 37 I2C_5#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 53 N/A 6 GPIO7 22 INTERRUPT_PIN 38 I2C_6#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 54 N/A 7 GPIO8 23 N/A 39 I2C_7#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 55 N/A 8 GPIO9 24 N/A 40 SREG0_0#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 56 N/A 9 GPIO10 25 N/A 41 SREG0_1#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 57 N/A 10 GPIO11 26 N/A 42 SREG0_2#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 58 N/A 11 BUCK1_PG 27 N/A 43 SREG0_3#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 59 N/A 12 BUCK2_PG 28 N/A 44 SREG0_4#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 60 N/A 13 BUCK3_PG 29 N/A 45 SREG0_5#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 61 N/A 14 BUCK4_PG 30 N/A 46 SREG0_6#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 62 0 15 BUCK5_PG(use for EXT_VMON PowerGood) 31 N/A 47 SREG0_7#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 63 1 Conditions GPIO1..GPIO6 are only processed if the associated GPIOx pins are configured as GPIO Conditions I2C0..7 refer to register bits TRIGGER_I2C_0..7, and are located in register FSM_I2C_TRIGGER Conditions SREG0_0...7 refer to bits 9...7 in PFSM storage register R0 DELAY_IMM Command Description: Delay the execution by a specified time Assembly command: DELAY_IMM <Delay> Delay = delay time in ns, µs, ms, or s. If no unit is entered, this field must be an integer value between 0-63. Delay value is be rounded to the nearest achievable time based on the current step size. Current step size is based on the default NVM setting or a SET_DELAY value from a previous command. Assembler reports an error if the step size is too large or too small to meet the delay. Examples: DELAY_IMM 100 µs — Delay execution by 100 µs DELAY_IMM 10 ms — Delay execution by 10 ms DELAY_IMM 8 — Delay execution by 8 ticks of the current PFSM time step DELAY_SREG Command Description: Delay the execution by a time value stored in the specified scratch register. The delay is calculated based on the curernt step size based on the value stored in PFSM_DELAY_STEP, or a SET_DELAY value from a previous command. Assembly command: DELAY_SREG <PFSM Storage Register> PFSM Storage Register can be R0, R1, R2, or R3. Examples: DELAY_SREG R0 — Delay execution by the time value stored in PFSM storage register R0 TRIG_SET Command Description: Set a trigger destination address for a given input signal or condition. These commands must be defined at the beginning of PFSM configuration memory. Assembly command: TRIG_SET [DEST=]<Destination> [ID=]<Trig_ID> [SEL=]<Trig_sel> [TYPE=]<Trig_type> [IMM=]<IMM> [EXT=]<Memory space> 'DEST=', 'ID=', 'SEL='. 'TYPE=', 'IMM=', and 'EXT=' are options. When included, the parameters can be in any order. Destination is the label where this trigger starts executing. Trig_ID is the ID of the hardware trigger module to be configured (value range 0-27). They must be defined in numeric order based on the priority of the trigger. Trig_Sel is the 'Trigger Name' from the . This 'Trigger Name' is the trigger signal to be associated with the specified TRIG_ID. Trig_type = LOW, HIGH, RISE, or FALL. IMM can be either '0' or '1'. = '0' if the trigger is not activated until the END command of a given task; '1' if the trigger is activated immediately and can abort a sequence. REENTRANT can be either '0' or '1'. '1' permits a trigger to return to the current state, that allows a self-branching trigger to execute the current sequence again. Memory space can be either '0' or '1'. '0' indicates the destination address is in the PFSM memory space. '1' indicates the destination address is external and represents a FSM state ID. Examples: TRIG_SET seq1 20 GPIO_1 LOW 0 0 — Set trigger 20 to be GPIO_1=Low, not immediate. When triggered, start executing at ‘seq1’ label. TRIG_SET DEST=seq2 ID=15 SEL=WD_ERROR TYPE=RISE IMM=0 EXT=0 — Set trigger 15 to be rising WD_ERROR trigger, not immediate. When triggered, start executing at ‘seq2’ label. TRIG_MASK Command Description: Sets a trigger mask that determines which triggers are active. Setting a ‘0’ enables the trigger, setting a ‘1’ disables (masks) the trigger. Assembly command: TRIG_MASK <Mask value> Mask Value = 28-bit mask in any literal integer format (decimal, hex, and so forth). Examples: TRIG_MASK 0x5FF82F0 — Set the trigger mask to 0x5FF82F0 END Command #GUID-829AAD39-C301-4ED7-A234-62018DE2CD53/X6385 shows the format of the END commands. END Command Format Bit[3:0] CMD 4 bits Description: Marks the final instruction in a sequential task Fields: CMD: Command opcode (0xC) Assembly command: END Configuration Memory Organization and Sequence Execution The configuration memory is loaded from NVM into an SRAM. shows an example configuration memory with only two configured sequences. Configuration Memory Script Example As soon as the PMIC state reaches the mission states, it starts reading from the configuration memory until it hits the first END command. Setting up the triggers (1-28) must be the first section of the configuration memory, as well as the first set of trigger configurations. The trigger configurations are read and mapped to an internal lookup table that contains the starting address associated with each trigger in the configuration memory. If the trigger destination is an FFSM state then the address contains the fixed state value. After the trigger configurations are read and mapped into the SRAM, these triggers control the execution flow of the state transitions. The signal source of each trigger is listed under . When a trigger or multiple triggers are activated, the PFSM execution engine looks up the starting address associated with the highest priority unmasked trigger, and starts executing commands until it hits an END command. The last commands before END statement is generally the TRIG_MASK command, which directs the PFSM to a new set of unmasked trigger configurations, and the trigger with the highest priority in the new set is serviced next. Trigger priority is determined by the Trigger ID associated with each trigger. The priority of the trigger decreases as the associated trigger ID increases. As a result, the critical error triggers are usually located at the lowest trigger IDs. The TRIG_SET commands specify if a trigger is immediate or non-immediate. Immediate triggers are serviced immediately, which involves branching from the current sequence of commands to reach a new target destination. The non-immediate triggers are accumulated and serviced in the order of priority through the execution of each given sequence until the END command in reached. Therefore, the trigger ID assignment for each trigger can be arranged to produce the desired PFSM behavior. The TRIG_MASK command determines which triggers are active at the end of each sequence, and is usually placed just before the END instruction. The TRIG_MASK takes a 28-bit input to allow any combination of triggers to be enabled with a single command. Through the definition of the active triggers after each sequence execution the TRIG_MASK command can be conceptualized as establishing a power state. The above sequence of waiting for triggers and executing the sequence associated with an activated trigger is the normal operating condition of the PFSM execution engine when the PMIC is in the MISSION state. The fixed device power FSM takes over control from the execution engine each time an event occurs that requires a transition from the MISSION state of the PMIC to a fixed device state.

The is used as an example state machine that is defined through the configuration memory using the configuration FSM instructions. Example of a Mission State-Machine Each power state (light blue bubbles in ) defines the ON or OFF state and the sequencing timing of the external regulators and GPIO outputs. This example defines four power states: STANDBY, ACTIVE, MCU ONLY, and DEEP_SLEEP/S2R three power states: STANDBY, ACTIVE and RETENTION states. The priority order of these states is as follows: ACTIVE MCU ONLY DEEP SLEEP/S2R STANDBY The transitions between each power state is determined by the trigger signals source pre-selected from . These triggers are then placed in the order of priority through the trigger ID assignment of each trigger source. The critical error triggers are placed first, some specified as immediate triggers that can interrupt an on-going sequence. The non-error triggers, which are used to enable state transitions during normal device operation, are then placed according to the priority order of the state the device is transitioning to. list the trigger signal sources, in the order of priority, used to define the power states and transitions of the example mission state machine shown in . This table also helps to determine which triggers must be masked by the TRIG_MASK command upon arriving a pre-defined power state to produce the desired PFSM behavior.

When an error occurs, which requires the device to enter directly to the SAFE RECOVERY state, the mask for this trigger must be removed while all other non-immediate triggers are masked. The device exits the mission states and the FFSM state machine takes over control of the device power states once this trigger is executed. Pre-Configured Hardware Transitions There are some pre-defined trigger sources, such as on-requests and off-requests, that are constructed with the combination of hardware input signals and register bits settings. This section provides more detail to these pre-defined trigger sources and shows how they can be utilized in the PFSM configuration to initiate state to state transitions. ON Requests ON requests are used to switch on the device, which then transitions the device from the STANDBY or the LP_STANDBY to the state specified by STARTUP_DEST[1:0]. After the device arrives at the corresponding STARTUP_DEST[1:0] operation state, the MCU must setup the SLEEP1 and NSLEEP2 signals accordingly before clearing the STARTUP_INT interrupt. Once the interrupt is cleared, the device stays or moves to the next state corresponding to the NSLEEP signals state assignment as specified in . #GUID-CF09F512-F01B-4591-9EAD-EE716C2976A4/SLVSEA76972 lists the available ON requests. ON Requests EVENT MASKABLE COMMENT DEBOUNCE nPWRON (pin) Yes Edge sensitive 50 ms ENABLE (pin) Yes Level sensitive 8 µs First Supply Detection (FSD) Yes VCCA > VCCA_UV and FSD unmasked N/A RTC ALARM Interrupt Yes N/A RTC TIMER Interrupt Yes N/A WKUP1 or WKUP2 Detection Yes Edge sensitive 8 µs LP_WKUP1 or LP_WKUP2 Detection Yes Edge sensitive N/A Recovery from Immediate and Orderly Shutdown No Recover from system errors which caused immediate or orderly shutdown of the device N/A If one of the events listed in #GUID-CF09F512-F01B-4591-9EAD-EE716C2976A4/SLVSEA76972 occurs, then the event powers on the device unless one of the gating conditions listed in #GUID-CF09F512-F01B-4591-9EAD-EE716C2976A4/SLVSEA71946 is present. ON Requests Gating Conditions EVENT MASKABLE COMMENT VCCA_OVP (event) No VCCA > VCCA_OVP Device stays in SAFE RECOVERY until VCCA < VCCA_OVP VCCA_UVLO (event) No VCCA < VCCA_UVLO VINT_OVP (event) No LDOVINT > 1.98 V VINT_UVLO (event) No LDOVINT < 1.62 V TSD (event) No Device stays in SAFE RECOVERY until temperature decreases below TWARN level The NPWRON_SEL NVM register bit determines whether the nPWRON/ENABLE pin is treated as a power on press button or a level sensitive enable switch. When this pin is configured as the nPWRON button, a short button press detection is latched internally as a device enable signal until the NPWRON_START_INT is cleared, or a long press key event is detected. The short button press detection occurs when an falling edge is detected at the nPWRON pin. When the NPWRON_START_MASK bit is set to '1', the device does no longer react to the changing state of the pin as the nPWRON press button. The nPWRON/ENABLE pin is a level sensitive pin when it is configured as an ENABLE pin, and an assertion enables the device until the pin is released. When the ENABLE_MASK bit is set to '1', the device does no longer react to the changing state of the pin as the ENABLE switch. OFF Requests An OFF request is used to orderly switch off the device. OFF requests initiate transition from any other mission state to the STANDBY state or the LP_STANDBY state depending on the setting of the LP_STANDBY_SEL bit. #GUID-117B0898-2FEC-4E9D-9F33-06019819BC63/SLVSEA7991 lists the conditions to generate the OFF requests and the corresponding destination state. OFF Requests EVENT DEBOUNCE LP_STANDBY_SEL BIT SETTING DESTINATION STATE nPWRON (pin) (long press key event) 8 s LP_STANDBY_SEL = 0 STANDBY LP_STANDBY_SEL = 1 LP_STANDBY ENABLE (pin) 8 µs LP_STANDBY_SEL = 0 STANDBY LP_STANDBY_SEL = 1 LP_STANDBY I2C_TRIGGER_0 NA LP_STANDBY_SEL = 0 STANDBY LP_STANDBY_SEL = 1 LP_STANDBY The long press key event occurs when the nPWRON pin stays low for longer than tLPK_TIME while the device is in a mission state. When the nPWRON or ENABLE pin is used as the OFF request, the device wakes up from the STANDBY or the LP_STANDBY state through the ON request initiated by the same pin. The NPWRON_START_MASK or the ENABLE_MASK must remain low in this case to allow the detection of the ON request initiated by the pin. If the device needs to enter the LP_STANDBY state through the OFF request, it is important that the state of the nPWRON or ENABLE pin must remain the same until the state transition is completed. Failure to do so may result in unsuccessful wake-up from the LP_STANDBY state when the pin re-initiates On request. Using the I2C_TRIGGER_0 bit as the OFF request enables the device to wake up from the STANDBY or the LP_STANDBY states through the detection of LP_WKUPn/WKUPn pins, as well as RTC alarm or timer interrupts. To enable this feature, the device must set the I2C_TRIGGER_0 bit to '1' while the NSLEEPn signals are masked, and the ON request (initialized by the nPWRON or ENABLE pins) must remain active. Also the interrupt bits ENABLE_INT, FSD_INT and the GPIOx_INT bits (for the GPIOx pins assigned as WKUP1 or WKUP2) must be cleared before setting the I2C_TRIGGER_0 bit to '1'. NSLEEP1 and NSLEEP2 Functions The SLEEP requests are activated through the assertion of nSLEEP1 or nSLEEP2 pins that are the secondary functions of the 11 GPIO pins. These pins can be selected through GPIO configuration using the GPIOx_SEL register bits. If the nSLEEP1 or nSLEEP2 pins are not available, the NSLEEP1B and NSLEEP2B register bits can be configured in place for their functions. The input of nSLEEP1 pin and the state of the NSLEEP1B register bit are combined to create the NSLEEP1 signal through an OR function. Similarly for the input of the nSLEEP2 pin and the NSLEEP2B register bit as they are combined to create the NSLEEP2 signal. A 1 → 0 logic level transition of the NSLEEP signal generates a sleep request, while a 0 → 1 logic level transition reverses the sleep request in the example PFSM from . When a NSLEEPn signal transitions from 1 → 0, it generates a sleep request to go from a higher power state to a lower power state. When the signal transitions from 0 → 1, it reverses the sleep request and returns the device to the higher power state. The NSLEEP1 signal is designed to control the SoC supply rails. The NSLEEP2 signal is designed to control the MCU supply rails. When NSLEEP1 signal changes from 1 → 0, depending on the state of NSLEEP2, the TPS6593-Q1 device exits ACTIVE state and enters either the MCU ONLY or the S2R states. When NSLEEP2 signal changes from 1 → 0, the device enters the S2R state regardless the state of NSLEEP1. When the NSLEEP2 input signal changes from 0 →1, the MCU supply rails are enabled and the device exits S2R state. Depending on the state of NSLEEP1 signal, the device enters either the MCU ONLY or the ACTIVE state. In order for the system to function correctly, the MCU rails must be enabled when the NSLEEP1 input signal changes from 0 →1, which enables the SOC supply rails. NSLEEP1 0 →1 transition is ignored if NSLEEP2 is 0. The NSLEEPn_MASK bit can be used to mask the sleep request associated with the corresponding NSLEEPn signal. When the NSLEEPn_MASK = 1, the corresponding NSLEEPn signal is ignored. shows how the combination of the NSLEEPn signals and NSLEEPn_MASK bits creates triggers A/B/C/D to the FSM to control the power state of the device. The states of the resources during ACTIVE, SLEEP, and DEEP SLEEP/S2R states are defined in the LDOn_CTRL and BUCKn_CTRL registers. For each resource, a transition to the MCU ONLY or the DEEP SLEEP/S2R states is controlled by the FSM when the resource is associated to the SLEEP or DEEP SLEEP/S2R states. shows the corresponding state assignment based on the state of the NSLEEPn and their corresponding mask signals using the example PFSM from .

Any one of these GPIO pins when configured as an input pin can be configured to wake up the device by setting GPIOn_SEL bit to select the WKUP1 or WKUP2 functions. In the example PFSM depicted in , when a GPIO pin is configured as a WKUP1 pin, a rising or falling edge detected at the input of this pin (configurable by the GPIOn_FALL_MASK and the GPIOn_RISE_MASK bits) wakes up the device to the ACTIVE state. Likewise if a GPIO pin is configured as a WKUP2 pin, a detected edge wakes up the device to the MCU ONLY state. If multiple edge detections of WKUP signals occur simultaneous, the device goes to the state in the following priority order: ACTIVE MCU ONLY When a valid edge is detected at a WKUP pin, the nINT pin generates an interrupt to signal the MCU of the wake-up event, and the GPIOx_INT interrupt bit is set. The wake request remains active until the GPIOx_INT bit is cleared by the MCU. While the wake request is executing, the device does not react to sleep requests to enter a lower power state until the corresponding GPIOx_INT interrupt bit is cleared to cancel the wake request. After the wake request is canceled, the device returns to the state indicated by the NSLEEP1 and NSLEEP2 signals as shown in . LP_WKUP Pins for Waking Up from LP STANDBY The LP_WKUP functions are activated through the edge detection of LP_WKUP pins, configurable as secondary functions of GPIO3 and GPIO4. They are specially designed to wake the device up from the LP STANDBY state when a high speed wake-up signal is detected. Similar to the WKUP1 and WKUP2 pins, when GPIO3 or GPIO4 pin is configured as an LP_WKUP1 pin, a rising or falling edge detected at the input of this pin (configurable by the GPIOn_FALL_MASK and the GPIOn_RISE_MASK bits) wakes up the device to the ACTIVE state. Likewise, if the pin is configured as an LP_WKUP2 pin, a detected edge wakes up the device to the MCU ONLY state. If multiple edge detections of LP_WKUP signals occur simultaneously, the device goes to the state in the following priority order: ACTIVE MCU ONLY Due to a digital control erratum in the device, the ENABLE_MASK/NPWRON_START_MASK bit must be set to '1' before the device enters LP_STANDBY state in order for the LP_WKUP2 pin to correctly wake up the device to the MCU_ONLY state. The TPS6593-Q1 device supports limited CAN wake-up capability through the LP_WKUP1/2 pins. When an input signal (without deglitch) with logic level transition from high-to-low or low-to-high with a minimum pulse width of tWK_PW_MIN is detected on the assigned LP_WKUP1/2 pins, the device wakes up asynchronously and executes the power up sequence. CAN-transceiver RXD- or INH-outputs can be connected to the LP_WKUP pin. If RXD-output is used, it is assumed that the transceiver RXD-pin IO is powered by the transceiver itself from an external supply when TPS6593-Q1 is in the LP_STANDBY state. If INH-signal is used it has to be scaled down to the recommenced GPIO input voltage level specified in the electrical characteristics table. In this PFSM example, the device can wake up from the LP_STANDBY state through the detection of LP_WKUP pins only if it enters the LP_STANDBY state through the TRIGGER_I2C_0 OFF request while the NSLEEPn signals are masked, and the on request initialized by the nPWRON/ENABLE pin remains active. Once a valid wake-up signal is detected at the LP_WKUP pin, it is handled as a WAKE request. The nINT pin generates an interrupt to signal the MCU of the wake-up event, and the corresponding GPIOx_INT interrupt bit is set. The wake request remains active until the interrupt bit is cleared by the MCU. shows how the device returns to the state indicated by the NSLEEP1 and NSLEEP2 signals after the wake request is canceled. illustrates the valid wake-up signal at the LP_WKUP1/2 pins, and the generation and clearing of the internal wake-up signal. CAN Wake-Up Timing Diagram Error Handling Operations The FSM engine of the TPS6593-Q1 device is designed to handle the following types of errors throughout the operation: Power Rail Output Error Boot BIST Error Runtime BIST Error Catastrophic Error Watchdog Error Error Signal Monitor (ESM) Error Warnings Power Rail Output Error A power rail output error occurs when an error condition is detected on the output rails of the device that are used to power the attached MCU or SoC. These errors include the following: Rails not reaching or maintaining within the power good voltage level threshold. A short condition that is detected at a regulator output. The load current that exceeds the forward current limit. The BUCKx_GRP_SEL, LDOn_GRP_SEL and VCCA_GRP_SEL registers are used to configure the rail group for all of the Bucks, LDOs, and the voltage monitors that are available for external rails. The selectable rail groups are MCU rail group, SoC rail group, or OTHER rail group. The TPS6593-Q1 device is designed to react differently when an error is detected from a power resource assigned to the different rail groups. shows how the SOC_RAIL_TRIG[1:0], MCU_RAIL_TRIG[1:0], and OTHER_RAIL_TRIG[1:0] register bits are used as the Immediate Shutdown Trigger Mask, Orderly Shutdown Trigger Mask, MCU Power Error Trigger Mask, or the SoC Power Error Trigger Mask. The settings of these register bits determine the error handling sequence that the assigned groups of rails perform in case of an output error. The PFSM engine can be configured to execute the appropriate error handling sequence for the following error handling sequence options: immediate shutdown, orderly shutdown, MCU power error, or SOC power error. For example, if an immediate shutdown sequence is assigned to the MCU rail group through the MCU_RAIL_TRIG[1:0] register bits, any failure detected in this group of rails causes the IMMEDIATE_SHUTDOWN trigger to be executed. This trigger is expected to start the immediate shutdown sequence and cause the device to enter the SAFE RECOVERY state. The device immediately resets the attached MCU and SoC by driving the nRSTOUT and nRSTOUT_SoC (GPO1 or GPIO11) pins low. All of the power resources assigned to the MCU and SOC shut down immediately without a sequencing order. The nINT pin signals that an MCU_PWR_ERR_INT interrupt event has occurred and the EN_DRV pin is forced low. If the error is recoverable within the recovery time interval, the device increments the recovery count, returns to INIT state, and reattempts the power up sequence (if the recovery count has not exceeded the counter threshold). If the recovery count has already exceeded the threshold, the device stays in the SAFE RECOVERY state until VCCA voltage is below the VCCA_UVLO threshold and the device is power-cycled. The power resources assigned to the SoC rail group are typically assigned to the SOC power error handling sequence. In this PFSM example depicted in , when a power resource in this group is detected, the PFSM typically causes the device to execute the shutdown of all the resources assigned to the SoC rail group, and the device enters the MCU ONLY state. The device immediately resets the attached SoC by toggling the nRSTOUT_SoC (GPO1 or GPIO11) pin. The reset output to the MCU and the resources assigned to the MCU rail group remain unchanged. The EN_DRV pin also remains unchanged, and the nINT pin signals that an SOC_PWR_ERR_INT interrupt event has occurred. To recover from the MCU_ONLY state after a SOC power error, the MCU software must set NSLEEP1 signal to '0' while NSLEEP2 signal remains '1'. This action signals TPS6593-Q1 that MCU has acknowledged the SOC power error, and is ready to return to normal operation. MCU can then set the NSLEEP1 signal back to '1' for the device to return to ACTIVE state and reattempt the SoC power up. Refer to for information regarding the setting of the NSLEEP1 and NSLEEP2 signals. The power resources used for peripheral devices in the system, for which no error-handling action is required, the rail mapping needs to be selected as "no group assigned". Catastrophic Error Catastrophic errors are errors that affect multiple power resources such as errors detected in supply voltage, LDOVINT supply for control logic, errors on internal clock signals, device temperature passing the thermal shutdown threshold, error detected on the SPMI bus, or an error detected in the PFSM sequence. Following errors are grouped as severe errors: VCCA > OVP threshold Junction temperature > immediate shutdown level Error in PFSM Sequence For these above listed errors, depending on the setting of bits SEVERE_ERR_TRIG[1:0], an immediate or orderly shutdown condition is created. The PFSM executes the corresponding sequence for the IMMEDIATE_SHUTDOWN trigger or the ORDERLY_SHUTDOWN trigger and enters the SAFE RECOVERY state. Following errors are grouped as moderate errors: Junction temperature > orderly shutdown level BIST failure CRC error in register map Recovery counter exceeding the threshold value Error on SPMI bus Readback error on nRSTOUT pin or nINT pin For these above listed errors, depending on the setting of bits MODERATE_ERR_TRIG[1:0], an immediate or orderly shutdown condition is created. The PFSM executes the corresponding sequence for the IMMEDIATE_SHUTDOWN trigger or the ORDERLY_SHUTDOWN trigger and enters the SAFE RECOVERY state. For following errors, the device performs an immediate shutdown and resets all internal logic circuits: VCCA < UVLO threshold Error on LDOVINT supply Errors on internal clock signals Unrecoverable CRC error in the SRAM memory of the PFSM For all of the above listed errors, the device resets the attached MCU and SoC by driving the nRSTOUT and the GPIO pin used as nRSTOUT_SoC (GPO1 or GPIO11) pins low. All of the power resources assigned to the attached MCUand SOC are shut down. The nINT pin is driven low to signal an interrupt event has occurred, and the EN_DRV pin is forced low. Watchdog (WDOG) Error Watchdog (WDOG) describes details about the Watchdog (WDOG) errors detection mechanisms. Warnings Warning are non-catastrophic errors. When such an error occurs while the device is in the operating states, the device detects the error and handles the error through the interrupt handler. These are errors such as thermal warnings, I2C, or SPI communication errors, or power resource current limit detection while the output voltage still maintains within the power good threshold. When these errors occur, the nINT pin is driven low to signal an interrupt event has occurred. The device remains in the operation state and the state of the EN_DRV pin, the power resources, and the reset outputs remain unchanged. The power resource current limit detection can, by setting bit EN_ILIM_FSM_CTRL=1, be configured such that it is handled as a Power Rail Output Error as described in . Device Start-up Timing shows the timing diagram of the TPS6593-Q1 after the first supply detection. Device Start-up Timing Diagram tINIT_REFCLK_LDO is the start-up time for the reference block. tINIT_NVM_ANALOG is the time for the device to load the default values of the NVM configurable registers from the NVM memory, and the start-up time for the analog circuits in the device. tINIT_REFCLK_LDO and tINIT_NVM_ANALOG are defined in the electrical characteristics table. BOOT_BIST is the sum of tLBISTrun (which is defined in the electrical characterization tables) and a less than 60us time-interval needed for the cyclic redundancy check on the register map and the SRAM. The Power Sequence time is the total time for the device to complete the power up sequence. Please refer to for more details. The reset delay time is a configurable wait time for the nRSTOUT and the nRSTOUT_SoC release after the power up sequence is completed. Power Sequences A power sequence is an automatic preconfigured sequence the TPS6593-Q1 device applies to its resources, which include the states of the BUCKs, LDOs, 32-kHz clock and the GPIO output signals. For a detailed description of the GPIOs signals, please refer to General-Purpose I/Os (GPIO Pins). shows an example of a power up transition followed by a power down transition. The power up sequence is triggered through a valid on request, and the power down sequence is trigger by a valid off request. The resources controlled (for this example) are: BUCK3, LDO1, BUCK2, LDO2, GPIO1 , LDO4, and LDO3. The time between each resource enable and disable (TinstX) is also part of the preconfigured sequence definition. A resource not assigned to any power sequence remains in off mode during the power-up sequence. The attached MCU or SoC can enable and configure this resource independently when the power-up sequence completes. Also the EN_DRV remains low during the power-up sequence. The attached MCU or SoC can release the EN_DRV pin by setting the ENABLE_DRV bit (requires running watchdog, ESM started and no pending interrupt bits). Power Sequence Example As the power sequences of the TPS6593-Q1 device are defined according to the processor requirements, the total time for the completion of the power sequence varies across various system definitions. First Supply Detection The TPS6593-Q1 device can be configured to automatically start up from a first supply-detection (FSD) event detection. This feature is enabled by setting the FSD_MASK register bit to '0', and setting the NPWRON_SEL[1:0] registers bits to '10' or '11' to mask the functionality of the nPWRON/ENABLE pin. When the device is powered up from the NO SUPPLY state, the FSD detection is validated after the NVM default for this feature is loaded into the device memory. When the FSD feature is enabled, the PMIC immediately powers up from the NO SUPPLY state to an operation state, configured by the STARTUP_DEST[1:0] bits when VCCA > VCCA_UV, while VCCA_UV gating is performed, and only when VCCA voltage monitoring is enabled (VCCA_VMON_EN = 1). After the device arrives the corresponding STARTUP_DEST[1:0] operation state, the MCU must setup the NSLEEP1 and NSLEEP2 signals accordingly before clearing the FSD_INT interrupt. Once the interrupt is cleared, the device either stays in the current state or moves to the destination state according to the state of the NSLEEP1 and NSLEEP2 signals as specified in . Register Power Domains and Reset Levels The TPS6593-Q1 registers are defined by the following categories: LDOVINT registers LDOVRTC registers (registers in RTC domain) LDOVINT registers The LDOVINT registers are powered by the internal LDOVINT, and retain their values until the device enters the LP_STANDBY state or the BACKUP state after the device was fully powered up and in operation. When this occurs, LDOVINT is powered off, all LDOVINT registers (including the VSET registers which store the output voltage levels for all of the external power rails) are reset. As the device re-enters the INIT state from a wake up signal or an On-request, the registers powered by the LDOVINT are re-written with the default values from NVM (Non-Volatile Memory). All registers in the device, except the LDOVRTC registers (registers in RTC domain), are powered by LDOVINT. LDOVRTC registers (registers in RTC domain) The LDOVRTC registers (registers in RTC domain) retain their values until a Power-On-Reset (POR) occurs. POR occurs when the device loses supply power and enters the NO SUPPLY state. When this occurs, LDOVRTC is powered off, and all LDOVRTC registers are reset. Following are the LDOVRTC registers: All RTC registers RTC and Crystal Oscillator bits Status registers for the following events: TSD and RTC reset Control registers for PWRON/ENABLE, GPIO3, and GPIO4 pins (for wake signal monitor during LP_STANDBY state) Following interrupt registers: FSD_INT RECOV_CNT_INT TSD_ORD_INT TSD_IMM_INT PFSM_ERR_INT VCCA_OVP_INT ESM_MCU_RST_INT ESM_SOC_RST_INT WD_RST_INT WD_LONGWIN_TIMEOUT_INT NPWRON_LONG_INT Multi-PMIC Synchronization A 20220110 Changed all instances of legacy terminology into "controller" and "target", also in all sub-sectionsyes A multi-PMIC synchronization scheme is implemented in the TPS6593-Q1 device to synchronize the power state changes with other PMIC devices. This feature consolidates and simplifies the IO control signals required between the application processor or the microcontroller and multiple PMICs in the system. The control interface consists of an SPMI protocol that communicates the next power state information from the primary PMIC to up to 5 secondary PMICs, and receives feedback signal from the secondary PMICs to indicate any error condition or power state information. is the block diagram of the power state synchronization scheme. The primary PMIC in this block diagram is responsible for broadcasting the synchronous system power state data, and processing the error feedback signals from the secondary PMICs. The primary PMIC is the controller device on the SPMI bus, and the secondary PMICs are the target devices on the SPMI bus. Multi-PMIC Power State Synchronization Block Diagram In this scheme, each primary and secondary PMIC runs on its own system clock, and maintains its own register map. Each PMIC monitors its own activities and pulls down the open-drain output of nINT or PGOOD pin when errors are detected. The microprocessor must read the status bits from each PMIC device through the I2C or SPI interface to find out the source of the error that is reported. To synchronize the timing when entering and exiting from the LP_STANDBY state, the VOUT_LDOVINT of the TPS6593-Q1 device must be connected to the ENABLE input of the secondary PMICs, which are the target devices in the SPMI interface bus. illustrates the pin connections between the primary, the secondary, and the application processor or the System-on-Chip. Multi-PMIC Pin Connections The power sequencer of the multiple PMICs are synchronized at the beginning of each power up and power down sequence; a variation in the sequence timing, however, is still possible due to the ±5% clock accuracy of the independent system clocks on the primary and secondary PMICs. The worst-case sequence timing variation from different PMIC rails is up to ±10% of the target delay time. illustrates the creation of this timing variation between PMICs. Multi-PMIC Rail Sequencing Timing Variation SPMI Interface System Setup An SPMI interface in the TPS6593-Q1 device is utilized to communicate the power state transition across multiple PMICs in the system. The SPMI interface contains a controller block and a target block. There is only one PMIC, which is the primary PMIC, that acts as SPMI controller in any given system. As the SPMI controller it initiates SPMI interface BIST and executes periodic checking of the SPMI bus health. The primary PMIC has a controller-ID (CID)= 1. The target block of SPMI interface in the primary PMIC device is activated as well, in order to receive SPMI communication messages from the secondary PMICs. The primary PMIC has a target-ID (TID) = 0101. Each secondary PMIC on the SPMI network only has the target block of its SPMI interface enabled. There cannot be more than five secondary PMICs in the system. The target-IDs (TIDs) for the five secondary PMICs are: 1st target device: 0011 2nd target device: 1100 3rd target device: 1001 4th target device: 0110 5th target device: 1010 All devices in the SPMI network listen to the group target-ID (GTID): 1111. This address is used to communicate all power state transition information in broadcast mode to all connected devices on the SPMI bus. Transmission Protocol and CRC The communication between the devices on the network utilizes Extended Register Write command to GTID address 1111 with byte length of 2. Sequence format complies with MIPI SPMI 2.0 specification. First data frame carries the data payload of 5 bits and 3 filler bits. Communication over the SPMI interface may contain information regarding the power state transition or the unique TID of one or more target devices. In the case of power state information, the data payload contains 5 bits of Trigger ID information and 3 trigger state bits. In the case of TID information, all 8 bits contain the TID of the target device. Second data frame carries 8 bits of CRC information. CRC polynomial used is X8 + X2 + X + 1. CRC is calculated over the SPMI command frame, the address frame, and the first data frame (which contains the payload and excludes the parity bits in these three frames). shows the data format of the SPMI Extended Register Write Command. SPMI Extended Register Write Command Operation with Transmission Errors If the receiving device detects a parity or CRC error in the incoming sequence it responds with negative ACK/NACK per SPMI standard. If the transmitting device sees NACK response, it tries to resend the message as many times as indicated by SPMI_RETRY_LIMIT register bits. After that it considers the SPMI bus inoperable, sets SPMI_ERR_INT interrupt and goes to the safe recovery state and executes an orderly shutdown. Bus arbitration requests do not count as failed attempts if a target device loses bus arbitration. SPMI_RETRY_LIMIT counter is reset after each successful transmission by the device. If a target device has determined that SPMI does not work reliably it does not respond to any SPMI commands anymore until power-on-reset event has occurred. This "no-response" behavior is to prevent continued operation in a situation where SPMI is unreliable. If a target device does no longer respond to any SPMI command, the controller device on the SPMI bus detects a missing target device on the network during the periodic testing of SPMI bus. The target device then internally handles the SPMI error condition per error handling rules set for the device (in general executing an orderly shutdown). SPMI block signals to the device that SPMI bus error has occurred after the retry limit has been exceeded. Transmitted Information The SPMI bus is used to carry two types of information: PFSM Trigger ID between the SPMI controller and target devices TID from SPMI target devices to SPMI controller device The SPMI controller device reads the TID of the target devices periodically to check the health of the interface. Exchanging Trigger IDs for the power state transition is sufficient to keep the PFSMs of all the devices on the SPMI network in synchronization. Device interrupts explain reason for the power state transitions. SPMI Target Device Communication to SPMI Controller Device An SPMI target device communicates to the SPMI controller device and any other SPMI target devices, only if there is an internal error that is not SPMI related. The target device initiates the error communication using Arbitration Request with A-bit as defined in the SPMI 2.0 specification. SPMI 2.0 protocol manages the situation with multiple target devices requesting error communication at the same time, by using the target arbitration process as described in SPMI 2.0 specification. Once the SPMI target device wins the arbitration using the A-bit protocol, it performs an Extended Register Write command to Group Target ID (GTID) address 1111 by using the protocol described in for communicating PFSM trigger ID. Incomplete Communication from SPMI Target Device to SPMI Controller Device In case the SPMI controller device detects an arbitration request on the SPMI interface, but the received sequence has an error or is incomplete, the SPMI controller device immediately performs the SPMI Built-In Self-Test (SPMI-BIST). If this SPMI-BIST fails, the SPMI controller device executes the error handling for the SPMI error. If the SPMI-BIST passes successfully, the SPMI controller device resumes normal operation. SPMI-BIST Overview The SPMI-BIST is performed during BIST state and regularly during runtime operation. below illustrates how the SPMI-BIST operates during device power-up. SPMI-BIST Operation After the input power is detected and verified to be at the correct level, the TPS6593-Q1 initializes itself by reading the NVM and performs all actions that are needed to prepare for operation. After this initialization, the TPS6593-Q1 enters the BOOT BIST state, in which the internal logic performs a series of tests to verify that the TPS6593-Q1 device is OK. As part of this test, the SPMI- BIST is performed. After it is completed successfully, the TPS6593-Q1 device goes to the standby state and waits for further signals from the system to initiate the power-up sequence of the processor. A valid on request initiates the processor power-up sequence. The controller device communicates this event through the SPMI bus to all of the target devices. After that, the power-up sequence is executed and TPS6593-Q1 enters the configured mission state. SPMI Bus during Boot BIST and RUNTIME BIST During Boot BIST and RUNTIME BIST, both the Logic BIST (LBIST) on the SPMI logic and the SPMI-BIST are performed to check correct operation of the SPMI bus. The LBIST is performed first before the SPMI-BIST during BOOT BIST and RUNTIME BIST. The SPMI-BIST is implemented by reading TID from each target device on the SPMI bus into the controller device, and ensuring they are unique and match the expected amount of target devices. This process of checking the TID of each target device ensures that: All SPMI target devices are present in the system as expected The SPMI logic blocks are working on the SPMI controller device and all of the SPMI target devices The pins and wires on the ICs and PCB are in working order The SPMI-BIST is initiated by the SPMI controller block in the primary PMIC by writing a request to all SPMI target device(s) (using GTID) to send their TIDs to the SPMI controller block of the primary PMIC. Upon receiving this command from the SPMI controller device, the SPMI target devices request SPMI bus arbitration using the SR-bit protocol. Upon winning the bus arbitration the SPMI target devices transmit their TID into the SPMI target block of the primary PMIC. The SPMI controller block of the primary PMIC contains a list of all SPMI target device(s) on the SPMI bus and their TIDs in the register set. The SPMI controller block of the primary PMIC reads the TID from each SPMI target device and compares the result with the stored TID for the corresponding SPMI target device. The SPMI controller device has to ensure that every non-zero TID on its list is returned, in order to support use cases in which there are two or more identical SPMI target devices, with same TID, in the system. In these cases, it is mandatory that the expected number of the same TIDs is returned. If no identical PMICs are to be used, then a return of the same TID multiple times is an error due to incorrect assembly of identical PMICs onto the PCB. An all-zero TID stored in the list of the primary PMIC indicates that there are no SPMI target device(s) present on the SPMI Bus. Periodic Checking of the SPMI The SPMI controller block in the primary PMIC executes the SPMI-BIST periodically while device is operating. The time-period after the SPMI-BIST is repeated according factory-configured settings during the device boot time, and after the device reaches mission states. The factory-configured settings of this SPMI-BIST time period must be the same for all PMICs on the same SPMI network. The SPMI target devices on the SPMI bus expect a request for sending its TID from the SPMI controller device within 1.5x the factory-configured period . This factor 1.5x provides enough margin for clock uncertainty between the SPMI controller device and the SPMI target device. During mission state operation, the SPMI controller device expects the SPMI target devices to respond to the TID request within the factory-configured polling time-out period . In other words, from the polling start command each SPMI target device must respond within this factory-configured time interval. During boot time or when the device enters Safe Recovery state, to prevent the SPMI controller device from polling the SPMI target devices too often while one or more of these recovering from a system error such as a thermal shutdown event, the device sets a longer timeout period that allows the SPMI target devices to respond to the SPMI controller device before he SPMI controller device reports an error. If one or more devices on the SPMI bus cause a violating of the polling time-out period either during start-up or during normal operation, the SPMI controller block in the affected PMIC(s) sets a SPMI error trigger signal to the PFSM of the affected PMIC(s), causing a complete shutdown of the affected PMIC(s). As a result, the affected PMIC(s) no longer respond on the SPMI bus, which in turn is detected by the SPMI controller block off the non-affected PMICs on the SPMI bus. The SPMI controller block in these PMICs sets an SPMI error to the PFSM in these PMICs, causing a complete shutdown of these PMICs. Therefore, all PMICs are finally shutdown if one or more devices on the SPMI bus cause a violating of the polling time-out period . SPMI Message Priorities The SPMI Bus uses the protocol priority levels listed in #GUID-F91E50E4-0CEA-4F17-B748-4E3A03F33999/SLVSE824332 for each type of communication message. SPMI Message Types and Priorities SPMI protocol priority level Name of priority level in SPMI standard Message types Highest A-bit arbitration State transition messages from target device(s) to controller device priority arbitration State transition messages from controller device to target device(s) SR-bit arbitration target device TID to controller device Lowest secondary arbitration Controller device request of TIDs from target device(s) Control Interfaces A 20220110 For I2C, changed all instances of legacy terminology into "controller" and "target". For SPI, changed all instances of legacy terminology into "controller" and "peripheral". For the CRC, changed all instances of legacy terminology into "CRC on received data (R_CRC)", and "CRC on transmitted data" (T_CRC). These changes also applies to all sub-sections.yes The device has two, exclusive selectable (from factory settings) interfaces. Please refer to the user's guide of the orderable part number which option has been selected. The first selection is up to two high-speed I2C interfaces. The second selection is one SPI interface. The SPI and I2C1 interfaces are used to fully control and configure the device, and have access to all of the configuration registers and Watchdog registers. During normal operating mode, when the I2C configuration is selected, and the GPIO1 and GPIO2 pins are configured as the SCL_I2C2 and SDA_I2C2 pins, the I2C2 interface becomes the dedicated interface for the Q&A Watchdog communication channel, while I2C1 interface no longer has access to the Watchdog registers. . CRC Calculation for I2C and SPI Interface Protocols A 20220110 Corrected figure on Calculation of 8-Bit Controller CRC (R_CRC) Output, corrected figure on Calculation of 8-Bit Target CRC (T_CRC) Inputyes For safety applications, the TPS6593-Q1 supports read and write protocols with embedded CRC data fields. The TPS6593-Q1 uses a standard CRC-8 polynomial to calculate the checksum value: X8 + X2 + X + 1. The CRC algorithm details are as follows: Initial value for the remainder is all 1s Big-endian bit stream order Result inversion is not applied For I2C Interface, the TPS6593-Q1 uses the above mentioned CRC-8 polynomial to calculate the checksum value on every bit except the ACK and NACK bits it receives from the MCU during a write protocol. The TPS6593-Q1 compares this calculated checksum with the R_CRC checksum value that it receives from the MCU. The TPS6593-Q1 also uses the above mentioned CRC-8 polynomial to calculate the T_CRC checksum value during a read protocol. This T_CRC checksum value is based on every bit that the TPS6593-Q1 receives, except the ACK and NACK bits, and the data that the TPS6593-Q1 transmits to the MCU during a read protocol. The MCU must use this same CRC-8 polynomial to calculate the checksum value based on the bits that the MCU receives from the TPS6593-Q1. The MCU must compare this calculated checksum with the T_CRC checksum value that it receives from the TPS6593-Q1. For the SPI interface, the TPS6593-Q1 uses the above mentioned CRC-8 polynomial to calculate the checksum value on every bit it receives from the MCU during a write protocol. The TPS6593-Q1 compares this calculated checksum with the R_CRC checksum value, that it receives from the MCU. During a read protocol, the device also uses the above mentioned CRC-8 polynomial to calculate the T_CRC checksum value based on the first 16 bits sent by the MCU, and the next 8 bits the TPS6593-Q1 transmits to the MCU. The MCU must use this same CRC-8 polynomial to calculate the checksum value based on the bits which the MCU sends to and receives from the TPS6593-Q1, and compare it with the T_CRC checksum value that it receives from the TPS6593-Q1. and are examples for the 8-bit R_CRC and the T_CRC calculation from 16-bit databus. Calculation of 8-Bit CRC on Received Data (R_CRC) Calculation of 8-Bit CRC on Transmitted Data (T_CRC) I2C-Compatible Interface The default I2C1 7-bit device address of the TPS6593-Q1 device is set to a binary value that is described in the user's guide of the orderable part number of the TPS6593-Q1 PMIC, while the two least-significant bits can be changed for alternative page selection listed under . The default 7-bit device address for the I2C2 interface, for accessing the watchdog configuration registers and for operating the watchdog in Q&A mode, is described in the user's guide of the orderable part number of the TPS6593-Q1 PMIC. The I2C-compatible synchronous serial interface provides access to the configurable functions and registers on the device. This protocol uses a two-wire interface for bidirectional communications between the devices connected to the bus. The two interface lines are the serial data line (SDA), and the serial clock line (SCL). Every device on the bus is assigned a unique address and acts as either a controller or a target depending on whether it generates or receives the serial clock SCL. The SCL and SDA lines must each have a pullup resistor placed somewhere on the line and remain HIGH even when the bus is idle. The device supports standard mode (100 kHz), fast mode (400 kHz), and fast mode plus (1 MHz) when VIO is 3.3 V or 1.8 V, and high-speed mode (3.4 MHz) only when VIO is 1.8 V. Data Validity The data on the SDA line must be stable during the HIGH period of the clock signal (SCL). In other words, the state of the data line can only be changed when clock signal is LOW. Data Validity Diagram Start and Stop Conditions The device is controlled through an I2C-compatible interface. START and STOP conditions classify the beginning and end of the I2C session. A START condition is defined as the SDA signal going from HIGH to LOW while the SCL signal is HIGH. A STOP condition is defined as the SDA signal going from LOW to HIGH while the SCL signal is HIGH. The I2C controller device always generates the START and STOP conditions. Start and Stop Sequences The I2C bus is considered busy after a START condition and free after a STOP condition. The I2C controller device can generate repeated START conditions during data transmission. A START and a repeated START condition are equivalent function-wise. shows the SDA and SCL signal timing for the I2C-compatible bus. For timing values, see the Specification section. I2C-Compatible Timing Transferring Data Every byte put on the SDA line must be eight bits long, with the most significant bit (MSB) being transferred first. Each byte of data has to be followed by an acknowledge bit. The acknowledge related clock pulse is generated by the controller device. The controller device releases the SDA line (HIGH) during the acknowledge clock pulse. The device pulls down the SDA line during the 9th clock pulse, signifying an acknowledge. The device generates an acknowledge after each byte has been received. There is one exception to the acknowledge after every byte rule. When the controller device is the receiver, it must indicate to the transmitter an end of data by not-acknowledging (negative acknowledge) the last byte clocked out of the target device. This negative acknowledge still includes the acknowledge clock pulse (generated by the controller device), but the SDA line is not pulled down. After the START condition, the bus controller device sends a chip address. This address is seven bits long followed by an eighth bit which is a data direction bit (READ or WRITE). For the eighth bit, a 0 indicates a WRITE and a 1 indicates a READ. The second byte selects the register to which the data is written. The third byte contains data to write to the selected register. shows an example bit format of device address 110000-Bin = 60Hex. Example Device Address For safety applications, the device supports read and write protocols with embedded CRC data fields. In a write cycle, the I2C controller device (the MCU) must provide the 8-bit CRC value after sending the write data bits and receiving the ACK from the target (the TPS6593-Q1 PMIC). The CRC value must be calculated from every bit included in the write protocol except the ACK bits from the target. See CRC Calculation for I2C and SPI Interface Protocols. In a read cycle, the I2C target must provide the 8-bit CRC value after sending the read data bits and the ACK bit, and expect to receive the NACK from the controller at the end of the protocol. The CRC value must be calculated from every bit included in the read protocol except the ACK and NACK bits. See CRC Calculation for I2C and SPI Interface Protocols.If I2C CRC is enabled in the device and an I2C write without R_CRC bits is done, the device does not process the write request. The device does not set any interrupt bit and does not pull the nINT pin low. The embedded CRC field can be enabled or deactivated from the protocol by setting the I2C1_SPI_CRC_EN register bit to '1' - enabled, '0' - deactivated. The default of this bit is configurable through the NVM. In case the calculated CRC-value does not match the received CRC-check-sum, an I2C-CRC-error is detected, the COMM_CRC_ERR_INT bit is set, unless it is masked by the COMM_CRC_ERR_MASK bit. The MCU must clear this bit by writing a ‘1’ to the COMM_CRC_ERR_INT bit. When the CRC field is enabled, in the case when MCU attempts to write to a read-only register or a register-address that does not exist, the device sets the COMM_ADR_ERR_INT bit, unless the COMM_ADR_ERR_MASK bit is set. The MCU must clear this bit by writing a ‘1’ to the COMM_ADR_ERR_INT bit. I2C Write Cycle without CRC I2C Write Cycle with CRC The I2C controller device (the MCU) provides R_CRC[7:0], which is calculated from the I2C_ID, R/W, ADDR, and the WDATA bits (24 bits). See CRC Calculation for I2C and SPI Interface Protocols. I2C Read Cycle without CRC When READ function is to be accomplished, a WRITE function must precede the READ function as shown above. I2C READ Cycle with CRC The I2C target device (the TPS6593-Q1) provides T_CRC[7:0], which is calculated from the I2C_ID, R/W, ADDR, I2C_ID, R/W, and the RDATA bits (32 bits). See CRC Calculation for I2C and SPI Interface Protocols. Auto-Increment Feature The auto-increment feature allows writing several consecutive registers within one transmission. Every time an 8-bit word is sent to the device, the internal address index counter is incremented by one and the next register is written. #GUID-9513D4D5-9FCE-433D-8352-4E7C139123AC/SNVSA484054 lists the writing sequence to two consecutive registers. Note that auto increment feature does not support CRC protocol. Auto-Increment Example ACTION START DEVICE ADDRESS = 0x60 WRITE REGISTER ADDRESS DATA DATA STOP PMIC device ACK ACK ACK ACK Serial Peripheral Interface (SPI) The device supports SPI serial-bus interface and it operates as a peripheral device. The MCU in the system acts as the controller device. A single read and write transmission consists of 24-bit write and read cycles (32-bit if CRC is enabled) in the following order: Bits 1-8: ADDR[7:0], Register address Bits 9-11: PAGE[2:0], Page address for register Bit 12: Read/Write definition, 0 = WRITE, 1 = READ. Bits 13-16: RESERVED[4:0], Reserved, use all zeros. For Write: Bits 17-24: WDATA[7:0], write data For Write with CRC enabled: Bits 25-32: R_CRC[7:0], CRC error code calculated from bits 1-24 sent by the controller device (the MCU). See . For Read: Bits 17-24: RDATA[7:0], read data For Read with CRC enabled: Bits 25-32: T_CRC[7:0], CRC error code calculated from bits 1-16 sent by the controller device (the MCU), and bits 17-24, sent by the peripheral device (the TPS6593-Q1). See . The embedded CRC filed can be enabled or deactivated from the protocol by setting the I2C1_SPI_CRC_EN register bit to '1' - enabled, '0' - deactivated. The default of this bit is configurable through the NVM. The SDO output is in a high-impedance state when the CS pin is high. When the CS pin is low, the SDO output is always driven low except when the RDATA or SCRC bits are sent. When the RDATA or SCRC bits are sent, the SDO output is driven accordingly. The address, page, data, and CRC are transmitted MSB first. The chip-select signal (CS) must be low during the cycle transmission. The CS signal resets the interface when it is high, and must be taken high between successive cycles. Data is clocked in on the rising edge of the SCLK clock signal and it is clocked out on the falling edge of SCLK clock signal. The SPI Timing diagram shows the timing information for these signals. SPI Write Cycle SPI Write Cycle with CRC SPI Read Cycle SPI Read Cycle with CRC Due to a digital control erratum in the device, the TPS6593-Q1 pulls the nINT pin low and sets interrupt bit COMM_FRM_ERR_INT if the pin CS_SPI is low during device power-up and goes high after completion of the device power-up sequence. After system start-up, the MCU must clear this COMM_FRM_ERR_INT bit such that the TPS6593-Q1 can release the nINT pin. Configurable Registers Register Page Partitioning A 20220110 Added note which explains the I2C addresses for each register map page on the I2C bus. Added note which explains how each register map page is addressed when using SPI.yes The registers in the TPS6593-Q1 device are organized into five internal pages. Each page represents a different type of register. The below list shows the pages with their register types: Page 0: User Registers Page 1: NVM Control, Configuration, and Test Registers Page 2: Trim Registers Page 3: SRAM for PFSM Registers Page 4: Watchdog Registers When I2C Interfaces are used, each of the above listed register pages has its own 6-bit I2C device address. In order to address Page 0 to 3, the two LSBs if the pre-configured I2C1_ID are replaced with 00 for Page 0, 01 for Page 1, 10 for Page 2 and 11 for Page 3. As an example, if I2C1_ID=0x26 (0100110b) , Page 0 to 3 have following addresses: Page 0: 0100100 Page 1: 0100101 Page 2: 0100110 Page 3: 0100111 For Page 4 the I2C device address is according register bits I2C2_ID. Therefore, in case both I2C1 and I2C2 Interfaces are used, each TPS6593-Q1 device occupies four I2C device addresses (for Page 0, Page 1, Page 2 and Page 3) on the I2C1 bus and one I2C device address (for Page 4) on the I2C2 bus. And in case only I2C1 Interfaces is used, each TPS6593-Q1 device occupies five I2C device addresses (for Page 0, Page 1, Page 2, Page 3 and Page 4) on the I2C1 bus. In case multiple devices are used on a common I2C bus, care must be taken to avoid overlapping I2C device addresses. When SPI Interface is used, the above listed register pages are addresses with the PAGE[2:0] bits: 0x0 addresses Page 0, 0x1 addresses Page 1, 0x2 addresses Page 2, 0x3 addresses Page 3 CRC Protection for Configuration, Control, and Test Registers The TPS6593-Q1 device includes a CRC-16 engine to protect all the static registers of the device. Static registers are registers in Page 1, 2, and 3, with values that do not change once loaded from NVM. The CRC-16 engine continuously checks the control registers and the SRAM in the TPS6593-Q1. The expected CRC-16 value is stored in the NVM. When the CRC-16 engine detects a mismatch between the calculated and expected CRC-16 values, the interrupt bit REG_CRC_ERR_INT is set and the device forces an orderly shutdown sequence to return to the SAFE RECOVERY state. The device NVM control, configuration, and test registers in page 1 are protected against read or write access when the device is in normal functional mode. . The CRC-16 engine uses a standard CRC-16 polynomial to calculate the internal known-good checksum-value, which is X16 + X14 + X13 + X12 + X10 + X8 + X6 + X4 + X3 + X + 1. The initial value for the remainder of the polynomial is all 1s and is in big-endian bit-stream order. The inversion of the calculated result is enabled. The CRC-16 engine assumes a default value of '0' for all undefined or reserved bits in all control registers. Therefore, the software MUST NOT write the value of '1' to any of these undefined or reserved bits. If the value of '1 is written to any undefined or reserved bit of a writable register, the CRC-16 engine detects a mismatch between the calculated and expected CRC-16 values, and hence the interrupt bit REG_CRC_ERR_INT is set and the device forces an orderly shutdown sequence to return to the SAFE RECOVERY state. CRC Protection for User Registers A 20220110 Added note about writing to RESERVED bits causing a Register Map CRC erroryes At device power-up, after the NVM data is loaded into the register map, the TPS6593-Q1 performs an initial CRC check on the User Registers. These User Registers are located in page 0 and page 4 of the register map. For this initial CRC check on the User Registers, the TPS6593-Q1 uses the same CRC-16 engine and polynomial as described in , and compares the calculated CRC-16 values against the reference CRC-16 values read from the NVM. After power-up, the content of these User Registers can change due to a write-access through an I2C or SPI interface, or by the PFSM during a state transition. To protect the content of these User Registers during operation, the TPS6593-Q1 uses a dynamic CRC-8 engine for each 128-bit segment. When a write-access occurs to the User Registers, the dynamic CRC-8 engine calculates the checksum value of the current data in the accessed segment before the update to confirm that the data in the access segment before the update is still correct. In parallel, the CRC-8 engine calculates a new checksum value of the data from the same segment, with the new data inserted at the intended register address. If the checksum on the current data before the update is correct, the new calculated checksum value is used for the next CRC cycles. During operation, the checksum value are continuously computed and verified in a round-robin fashion. The CRC-8 engine utilizes the Polynomial(0xA6) = X8 + X6 + X3 + X2 + 1, which provides a H4 hamming distance. If a RESERVED bit in a R/W configuration register gets set to 1h through a I2C/SPI write, the TPS6593-Q1 detects a CRC error in the register map. Therefore, it is important that system software involved in the I2C/SPI write-access to the TPS6593-Q1 keeps all RESERVED bits (all bits with the word RESERVED in the Register Field Description tables in the Register Map section at 0h. Register Write Protection For safety application, in order to prevent unintentional writes to the control registers, the TPS6593-Q1 device implements locking and unlocking mechanisms to many of its configuration/control registers described in the following subsections. Watchdog and ESM Configuration Registers The configuration registers for the watchdog and the ESM are locked when their monitoring functions are in operation. The locking mechanism and the list of the locked watchdog register is described under . The locking mechanism and the list of the locked ESM registers is described under Error Signal Monitor (ESM) User Registers User registers in page 0, except the ESM and the WDOG configuration registers described in , and the interrupt registers (x_INT) at address 0x5a through 0x6c in page 0, can be write protected by a dedicated lock. User must write '0x9B' to the REGISTER_LOCK register to unlock the register. Writing any value other than '0x9B' activates the lock again. To check the register lock status, user must read the REGISTER_LOCK_STATUS bit. When this bit is '0', it indicates the user registers are unlocked. When this bit is '1', the user registers are locked. During start-up sequence such as powering up for the first time, waking up from LP_STANDBY, or recovering from SAFE_RECOVERY, the user registers are unlocked automatically.

Note: The GET_TIME bit has to be set to 0 and again to 1 to get a new timing value.

Detailed Description Overview The TPS6593-Q1 device is a Power-Management Integrated Circuit (PMIC), available in a 56-pin, 0.5-mm pitch, 8-mm × 8-mm QFN package. The TPS6593-Q1 is designed for powering embedded systems or System on Chip (SoC) in automotive or industrial applications. The TPS6593-Q1 provides five configurable BUCK regulators, of which four rails have the ability to combine outputs in multi-phase mode. BUCK4 has the ability to supply up to 4 A output current in single-phase mode, while BUCK1, BUCK2, and BUCK3 have the ability to supply up to 3.5 A output current in single-phase mode. When working in multi-phase mode, each BUCK1, BUCK2, BUCK3, and BUCK4 can supply up to 3.5 A output current per phase, adding up to 14 A output current in four-phase configuration. BUCK5 is a single-phase only BUCK regulator, which supports up to 2 A output current. All five of the BUCK regulators have the capability to sink a current up to 1 A, and support dynamic voltage scaling. Double-buffered voltage scaling registers enable each BUCK regulator to transition to a different voltage during operation by SPI or I2C. A digital PLL enables the BUCK regulators to synchronize to an external clock input, with phase delays between the output rails. The TPS6593-Q1 device also provides three LDO rails, which can supply up to 500 mA output current per rail and can be configured in bypass mode and used as a load switch. One additional low-noise LDO rail can supply up to 300 mA output current. The 500-mA LDOs support 0.6 V to 3.3 V output voltage with 50-mV step. The 300-mA low-noise LDO supports 1.2 V to 3.3 V output voltage with 25-mV step. The output voltages of the LDOs can be pre-configured through the SPI or I2C interfaces, which are used to configure the power rails and the power states of the TPS6593-Q1 device. I2C channel 1 (I2C1) is the main channel with access to the registers, which control the configurable power sequencer, the states and the outputs of power rails, the device operating states, the RTC registers and the Error Signal Monitors. I2C channel 2 (I2C2), which is available through the GPIO1 and GPIO2 pins, is dedicated for accessing the Q&A Watchdog communication registers. If GPIO1 and GPIO2 are not configured as I2C2 pins, I2C1 can access all of the registers, including the Q&A Watchdog registers. Alternatively, depending on the NVM-configuration of the orderable part number, SPI is the selected interface for the device and can be used to access all registers. The TPS6593-Q1 device includes an internal RC-oscillator to sequence all resources during power up and power down. Two internal LDOs (LDOVINT and LDOVRTC) generate the supply for the entire digital circuitry of the device as soon as the external input supply is available through the VCCA input. A backup battery supply input can also be used to power the RTC block and a 32-kHz Crystal Oscillator clock generator in the event of main supply power loss. TPS6593-Q1 device has eleven GPIO pins each with multiple functions and configurable features. All of the GPIO pins, when configured as general-purpose output pins, can be included in the power-up and power-down sequence and used as enable signals for external resources. In addition, each GPIO can be configured as a wake-up input or a sleep-mode trigger. The default configuration of the GPIO pins comes from the non-volatile memory (NVM), and can be re-programmed by system software if the external connection permits. The TPS6593-Q1 device includes a watchdog with selectable trigger or Q&A modes to monitor MCU software lockup, and two error signal monitor (ESM) inputs with fault injection options to monitor the lock-step signal of the attached SoC or MCU. TPS6593-Q1 includes protection and diagnostic mechanisms such as voltage monitoring on the input supply, voltage monitoring on all BUCK and LDO regulator outputs, CRC on configuration registers, CRC on non-volatile memory, CRC on communication interfaces, current-limit and short-circuit protection on all output rails, thermal pre-warning, and over-temperature shutdown. The device also includes a Q&A or trigger mode watchdog to monitor for MCU software lockup, and two Error Signal Monitor inputs with selectable level mode or PWM mode, and with fault injection options to monitor the error signals from the attached SoC or MCU. The TPS6593-Q1 can notify the processor of these events through the interrupt handler, allowing the MCU to take action in response. An SPMI interface is included in the TPS6593-Q1 device to distribute power state information to at most five satellite PMICs on the same network, thus enabling synchronous power state transition across multiple PMICs in the application system. This feature allows the consolidation of IO control signals from up to six PMICs powering the system into one primary TPS6593-Q1 PMIC.

The output voltages of the LDOs can be pre-configured through the SPI or I2C interfaces, which are used to configure the power rails and the power states of the TPS6593-Q1 device.TPS6593-Q1500 mA2TPS6593-Q1I2C channel 1 (I2C1) is the main channel with access to the registers, which control the configurable power sequencer, the states and the outputs of power rails, the device operating states, the RTC registers and the Error Signal Monitors. I2C channel 2 (I2C2), which is available through the GPIO1 and GPIO2 pins, is dedicated for accessing the Q&A Watchdog communication registers. If GPIO1 and GPIO2 are not configured as I2C2 pins, I2C1 can access all of the registers, including the Q&A Watchdog registers. Alternatively, depending on the NVM-configuration of the orderable part number, SPI is the selected interface for the device and can be used to access all registers. 2, the RTC registers2The TPS6593-Q1 device includes an internal RC-oscillator to sequence all resources during power up and power down. Two internal LDOs (LDOVINT and LDOVRTC) generate the supply for the entire digital circuitry of the device as soon as the external input supply is available through the VCCA input. A backup battery supply input can also be used to power the RTC block and a 32-kHz Crystal Oscillator clock generator in the event of main supply power loss. TPS6593-Q1A backup battery supply input can also be used to power the RTC block and a 32-kHz Crystal Oscillator clock generator in the event of main supply power loss. TPS6593-Q1 device has eleven GPIO pins each with multiple functions and configurable features. All of the GPIO pins, when configured as general-purpose output pins, can be included in the power-up and power-down sequence and used as enable signals for external resources. In addition, each GPIO can be configured as a wake-up input or a sleep-mode trigger. The default configuration of the GPIO pins comes from the non-volatile memory (NVM), and can be re-programmed by system software if the external connection permits.TPS6593-Q1 The TPS6593-Q1 device includes a watchdog with selectable trigger or Q&A modes to monitor MCU software lockup, and two error signal monitor (ESM) inputs with fault injection options to monitor the lock-step signal of the attached SoC or MCU. TPS6593-Q1 includes protection and diagnostic mechanisms such as voltage monitoring on the input supply, voltage monitoring on all BUCK and LDO regulator outputs, CRC on configuration registers, CRC on non-volatile memory, CRC on communication interfaces, current-limit and short-circuit protection on all output rails, thermal pre-warning, and over-temperature shutdown. The device also includes a Q&A or trigger mode watchdog to monitor for MCU software lockup, and two Error Signal Monitor inputs with selectable level mode or PWM mode, and with fault injection options to monitor the error signals from the attached SoC or MCU. The TPS6593-Q1 can notify the processor of these events through the interrupt handler, allowing the MCU to take action in response.The TPS6593-Q1 device includes a watchdog with selectable trigger or Q&A modes to monitor MCU software lockup, and two error signal monitor (ESM) inputs with fault injection options to monitor the lock-step signal of the attached SoC or MCU. TPS6593-Q1TPS6593-Q1The device also includes a Q&A or trigger mode watchdog to monitor for MCU software lockup, and two Error Signal Monitor inputs with selectable level mode or PWM mode, and with fault injection options to monitor the error signals from the attached SoC or MCU.TPS6593-Q1An SPMI interface is included in the TPS6593-Q1 device to distribute power state information to at most five satellite PMICs on the same network, thus enabling synchronous power state transition across multiple PMICs in the application system. This feature allows the consolidation of IO control signals from up to six PMICs powering the system into one primary TPS6593-Q1 PMIC.TPS6593-Q1TPS6593-Q1 Functional Block Diagram Functional Block Diagram Feature Description System Supply Voltage Monitor The comparator module in TPS6593-Q1, which monitors the voltage on the VCCA pins, controls the power state machine of the device. VCCA voltage detection outputs determine the power states of the device as follows: VCCA_UVLO The TPS6593-Q1 returns to the BACKUP state. LDOVRTC is powered by the output of the Backup Supply Management (BSM) module during the BACKUP state. The device returns to the NO SUPPLY state and is completely shut down when the input supply of the LDOVRTC falls below the operating range. The device cannot return to the BACKUP state from the NO SUPPLY state. VCCA_UV The TPS6593-Q1 transitions from the NO SUPPLY state to the INIT state when the voltage on the VCCA pin rises above VCCA_UV during initial power-up. VCCA_OVP If the voltage on VCCA pin rises above the VCCA_OVP threshold while TPS6593-Q1 is in operation, then the device clears the ENABLE_DRV bit and starts the immediate shutdown sequence. A separate voltage comparator monitors whether or not the VCCA voltage is within the expected PGOOD range when VCCA is expected to be 5-V or 3.3-V. This voltage comparator checks at device power-up whether the voltage on the VCCA supply pin is above the VCCA_UV threshold. Refer to for additional detail on the operation of the PGOOD monitor function. LDOVINT, which is the internal supply to the digital core of the device, may attempt to restart the device when the input voltage at VCCA pin falls or stays between VCCA_UVLO and VCCA_UV voltage levels; the voltage at the VCCA pin, however, must be above the VCCA_UV voltage level for the device to power up properly. shows a block diagram of the VCCA input voltage monitoring. VCCA Monitor Power Resources (Bucks and LDOs) The power resources provided by the TPS6593-Q1 device includes synchronous, current mode control bucks and linear LDOs. These supply resources provide power to the external processors, components, and modules inside the TPS6593-Q1 device. The supply of the bucks, the PVIN_Bx pins, must connect to the VCCA pin externally. The supply of the LDOs, the PVIN_LDOx pins, may connect to the VCCA pin or a buck output which is at a lower voltage level than the VCCA. The voltage output of each power resource is continuously monitored by a dedicated analog monitor on an independent reference voltage domain. An unused regulator can also be used as a voltage monitor for an external rail by connecting the external rail to the FB_Bn the VOUT_LDOn pin. #GUID-4B7B2915-7E2F-4669-92C2-3E88664B9019/SLVSE825742 lists the power resources provided by the TPS6593-Q1 device.

All of the buck converters support the following features: Automatic mode control based on the loading (PFM or PWM mode) or Forced-PWM mode operation External clock synchronization option to minimize crosstalk Optional spread spectrum technique to reduce EMI Soft start AVS support with configurable slew-rate Windowed undervoltage and overvoltage monitors with configurable threshold Windowed voltage monitor for external supply when the buck converter is inactive Output Current Limit Short-to-Ground Detection on SW_Bx pins at start-up of the buck regulator When the outputs of these buck converters are combined in multi-phase configuration, it also supports the following features: Current balancing between the phases of the converter Differential voltage sensing from point of the load Phase shifted outputs for EMI reduction Optional dynamic phase shedding or adding There are two modes of operation for the buck converter, depending on the required output current: pulse-width modulation (PWM) and pulse-frequency modulation (PFM). The converter operates in PWM mode at high load currents of approximately 600 mA or higher. Lighter output current loads cause the converter to automatically switch into PFM mode for reduced current consumption. The device avoids pulse skipping and allows easy filtering of the switch noise by external filter components when forced-PWM mode is selected (BUCKn_FPWM = 1). The forced-PWM mode is the recommended mode of operation for the buck converter to achieve better ripple and transient performance. The drawback of this forced-PWM mode is the higher quiescent current at low output current levels. When operating in PWM mode the phases of a multi-phase regulator are automatically added or shed based on the load current level. The forced multi-phase mode can be enabled for lower ripple at the output. shows a block diagram of a single core. shows the interleaving switching action of the multi-phase converters. BUCK Core Block Diagram Example of PWM Timings, Inductor Current Waveforms, and Total Output Current in 4-Phase Configuration. (1) Multi-Phase Operation and Phase-Adding or Shedding The 4-phase converters (BUCK1, BUCK2, BUCK3, and BUCK4) switches each channel 90° apart under heavy load conditions. As a result, the 4-phase converter has an effective ripple frequency four times greater than the switching frequency of any one phase. In the same way, 3-phase converter has an effective ripple frequency three times greater and 2-phase converter has an effective ripple frequency two times greater than the switching frequency of any one phase; the parallel operation, however, decreases the efficiency at light load conditions. The TPS6593-Q1 can change the number of active phases to optimize efficiency for the variations of the load in order to overcome this operational inefficiency. The process in which the multi-phase buck regulator in case of increasing load current automatically increases the number of active phases is called phase adding. The process in which the multi-phase buck regulator in case of decreasing load current automatically decreases the number of active phases is called phase shedding. The concept is shown in . The converter can be forced to multi-phase operation by the BUCKn_FPWM_MP bit in BUCKn_CTRL1 register. If the regulator operates in forced multi-phase mode , each phase automatically operates in the forced-PWM mode. If the multi-phase operation is not forced, the number of phases are added and shed automatically to follow the required output current. Multiphase BUCK Converter Efficiency vs Number of Phases (Converters in PWM Mode) (1) Transition Between PWM and PFM Modes The forced-PWM mode operation with phase-adding or shedding optimizes efficiency at mid-to-full load. TheTPS6593-Q1 converter operates in PWM mode at load current of approximately 600 mA or higher. The device automatically switches into PFM mode for reduced current consumption when forced-PWM mode is not enabled (BUCKn_FPWM = 0) at lighter load-current levels. A high efficiency is achieved over a wide output-load-current range by combining the PFM and the PWM modes. Multi-Phase BUCK Regulator Configurations The control of the multi-phase regulator settings is done using the control registers of the primary BUCK regulator in the multi-phase configuration. The TPS6593-Q1 ignores settings in the following registers of the secondary and, if used, the tertiary and quaternary BUCK regulators : BUCKn_CTRL register, except BUCKn_VMON_EN BUCKn_CONF register BUCKn_VOUT_1 and BUCKn_VOUT_2 registers BUCKn_PG_WINDOW register Interrupt bits related to the secondary and, if sued, the tertiary and quaternary BUCK regulator, except BUCKn_ILIM_INT, BUCKn_ILIM_MASK and BUCKn_ILIM_STAT #GUID-E61220E0-AB07-48B8-BBB5-1EEC54C6C2D1/SLVSE828295 shows the supported Multi-Phase BUCK regulator configurations and the assigned primary BUCK regulator in each configuration. Primary BUCK Assignment for Supported Multi-phase Configuration Supported Multi-Phase BUCK Regulator Configuration Primary BUCK Assignment 4-Phase: BUCK1 + BUCK2 + BUCK3 + BUCK4 BUCK1 3-Phase: BUCK1 + BUCK2 + BUCK3 BUCK1 2-Phase: BUCK1 + BUCK2 BUCK1 2-Phase: BUCK3 + BUCK4 BUCK3 When the BUCK regulators are configured in 3-phase or 4-phase configurations, there are exceptions to the above list of registers that the TPS6593-Q1 ignores. The configuration registers are user-configurable for the voltage monitor function on BUCK3 and BUCK4 in a 4-phase configuration and BUCK3 in a 3-phase configuration. The UV/OV voltage monitors of these BUCK3 and BUCK4 regulators can be used to monitor external supply rails, by connecting these external rails to the FB_Bn pins of these BUCK3 and BUCK4 regulators. The following list of registers and register bits for BUCK3 and BUCK4 can be used to enable and set the target voltage for the external voltage monitoring function under such configuration: BUCKn_VMON_EN bit BUCKn_VSEL bit BUCKn_SLEW_RATE BUCKn_VOUT_1 and BUCKn_VOUT_2 registers BUCKn_PG_WINDOW register Customers are responsible for the values set in these registers when using BUCK3 or BUCK4 to monitor an external supply under the 3-phase or 4-phase configuration. If the voltage monitor function is not used under such a scenario, the FB_Bn pins must be connected to the reference ground, and the BUCKn_VMON_EN bits must be set to '0'. Spread-Spectrum Mode The TPS6593-Q1 device supports spread-spectrum modulation of the switching clock signal used by the BUCK regulators. Three factory-selectable modulation modes are available: the first mode is modulation from external input clock at the SYNCCLKIN pin; the second mode is modulating the input clock at the SYNCCLKIN pin using the DPLL; the third mode is modulating the internal 20-MHz RC-Oscillator clock using the DPLL. The spread-spectrum modulation mode is pre-configured in NVM. Changing this modulation mode during operation is not supported. The modulation frequency range is limited by the DPLL bandwidth. The max frequency spread for the input clock to the DPLL is ±18% to secure parametric compliance of the BUCK output performance. The internal modulation is inactive by default and can be enabled and configured after power up. Internal modulation is activated by setting the SS_EN control bit. The internal modulation must be inactive (SS_EN = 0) when changing the following parameter: SS_DEPTH[1:0] – Spread Spectrum modulation depth When internal modulation is enabled and configured, it can be made inactive by the system MCU during operation. The device transition to different mission states does not impact internal modulation when it is enabled and configured. Adaptive Voltage Scaling (AVS) and Dynamic Voltage Scaling (DVS) Support An AVS or a DVS voltage value can be configured by the attached MCU after the BUCK regulator is powered up to the default output voltage selected in register BUCKn_VSET1, that loads its default value from NVM. The purpose of the AVS/DVS voltage is to set the BUCK output voltage to enable optimal efficiency and performance of the attached SoC. All of BUCK regulators in the TPS6593-Q1 device support AVS and DVS voltage scaling changes. Once the AVS/DVS voltage value is written into the BUCKn_VSET1 or BUCKn_VSET2 register, and the MCU sets the BUCKn_VSEL register to select the AVS/DVS voltage, the output of the BUCK regulator remains at the AVS/DVS voltage level instead of the default voltage from NVM until one of the following events occur: Error that causes the device to re-initialize itself through a power cycle after reaching the SAFE RECOVERY state Error that causes the device to execute warm reset MCU configures the device to enter the LP STANDBY state shows the arbitration scheme for loading the output level of the BUCK regulator from the AVS register using the BUCKn_VSET control registers. AVS/DVS Configuration Register Arbitration Diagram The digital control block automatically updates the OV and UV threshold of the BUCK output voltage monitor during the AVS or DVS voltage change. When the output voltage is increased, the OV threshold is updated at the same time the BUCKn_VSETx is updated to the AVS voltage level, while the UV threshold is updated after a delay calculated by . When the output voltage is decreased, the UV threshold is updated at the same time the BUCKn_VSETx is updated to the AVS voltage level, while the OV threshold is updated after a delay calculated by . tPG_OV_UV_DELAY = (dV / BUCKn_SLEW_RATE) + tsettle_Bx In order to prevent erroneous voltage monitoring, the digital block also temporarily masks the results of the OV and UV monitor from the regulator output when the BUCK regulator is enabled and the voltage is rising to the BUCKn_VSETx level. The duration of the mask starts from the time the BUCK regulator is enabled. The BUCK OV monitor output is masked for a fixed delay time of tPG_OV_GATE, that is approximately 115 µs – 128 µs. The UV monitor output is masked for the time duration calculated by . The 370-µs additional delay time in the formula includes the start-up delay of the BUCK regulator, and the fixed delay after the ramp. tPG_UV_GATE = (BUCKn_VSET / BUCKn_SLEW_RATE) + 370 µs Because output capacitance, forward and negative current limits and load current of the BUCK regulator may affect the slew rate of the BUCK regulator output voltage, the delay time of tPG_UV_GATE may not be sufficient long for the slower slew rate setting when the target BUCK regulator output voltage is higher. Please refer to the PMIC user's guide for detail information about the supported voltage level and slew rate setting combinations of a particular orderable part number. and are timing diagrams illustrating the voltage change for AVS and DVS enabled BUCK regulators and the corresponding OV and UV monitor threshold changes.

The High-Side Current Limit, also referred to as Forward Current Limit, is for BUCK1..4 adjustable between 2.5 A and 5.5 A with 1-A steps with register bits BUCKx_ILIM[3:0]. For BUCK5, this Forward Current Limit has selectable levels 2.5 A and 3.5 A with register bits BUCK5_ILIM[3:0]. The Low-Side Current Limit, also referred to as Negative Current Limit, has a fixed value of typical 2 A. SW_Bx Short-to-Ground Detection Each BUCK regulator includes a SW_Bx Short-to-Ground Detection. This SW_Bx Short-to-Ground Detection monitors whether the SW_B1...SW_B5 pins have a short-to-ground condition, either caused by external short on these pins or caused by a short in the low-side power-FET of the BUCK regulator. This SW_Bx Short to Ground Detection is activated before the power-up of the BUCK regulator. When this function detects a short-to-ground condition on the SW_B1...SW_B5 pins, the TPS6593-Q1 aborts the power-up sequence and sets the corresponding interrupt bits BUCKx_SC_INT (x=1...5). After this, the TPS6593-Q1 transitions to the SAFE RECOVERY state, after which it performs an attempt to restart as described in . Sync Clock Functionality The TPS6593-Q1 device contains a SYNCCLKIN (GPIO10) input to synchronize switching clock of the BUCK regulator with the external clock. The block diagram of the clocking and PLL module is shown in . The external clock is selected when the external clock is available, and SEL_EXT_CLK = '1'. The nominal frequency of the external input clock is set by EXT_CLK_FREQ[1:0] bits in the NVM and it can be 1.1 MHz, 2.2 MHz, or 4.4 MHz. The external SYNCCLKIN clock must be inside accuracy limits (–18%/+18%) of the typical input frequency for valid clock detection. The EXT_CLK_INT interrupt is generated in case the external clock is expected (SEL_EXT_CLK = 1), but it is not available or the clock frequency is not within the valid range. The TPS6593-Q1 device can also generate a clock signal, SYNCCLKOUT, for external device use. The SYNCCLKOUT_FREQ_SEL[1:0] selects the frequency of the SYNCCLKOUT. Note: SYNCCLKOUT_FREQ_SEL[1:0] must stay static while SYNCCLKOUT is used, as changing the output frequency selection can cause glitches on the clock output. The SYNCCLKOUT is available through GPIO8, GPIO9, or GPIO10. Sync Clock and DPLL Module Low Dropout Regulators (LDOs) All of the LDO regulators in the TPS6593-Q1 device can be supplied by the system supply or another pre-regulated voltage source which are within the specified VIN range. The PVIN_LDOn voltage level must be equal or less than the VCCA voltage level to ensure proper operation of the LDOs. The default output voltages of all LDOs are loaded from the NVM memory and can be configured by the LDOn_VSET[7:0]. There is no hardware protection to prevent software from selecting an improper output voltage if the minimum level of PVIN_LDOn is lower than the dropout voltage of the LDO regulator in addition to the configured LDO output voltage. In such conditions, the output voltage droops to near the PVIN_LDOn level. Writing a RESERVED value to the LDOn_VSET[7:0] register bits causes a LDOn_OV_INT or LDOn_UV_INT interrupt. The LDO regulators do not have slew rate control for voltage ramp; by setting the LDOn_SLOW_RAMP bit to '1', however, the ramp up speed of the regulator output voltage is < 3 V/ms. If an LDO is not needed, its associated UV/OV Voltage Monitor can be used to monitor an external voltage rail by connecting the external rail to the VOUT_LDOn pin. The voltage level of the monitored external rail must be within the PGOOD monitor range of the LDOn_VSET[7:0] of the LDO. If an external resistor divider is necessary in this case, the user must take into account the input impedance at the VOUT_LDOn pin (as shown in ), and adjust the resistor values to compensate for the voltage shift. Impedance at the VOUT_LDOn Pins LDOVINT The LDOVINT voltage regulator is dedicated to supply the digital and analog functions of the TPS6593-Q1 device, which are not required to be always-on and can be turned-off when the device is in low power states. The LDOVINT voltage regulator is automatically turned on and off as needed if LP_STANDBY_SEL = '1'. The automatic control optimizes the overall current consumption when the device is in low power LP_STANDBY state. The LDOVINT voltage regulator is dedicated for internal use only, and cannot be used to support external loads. An output filtering capacitor must be connected at the VOUT_LDOVINT pin. Do not connect any other components or external loads to this VOUT_LDOVINT pin. LDOVRTC The LDOVRTC voltage regulator supplies always-on functions, such as wake-up functions. This power resource is active as soon as a valid VCCA is present. The LDOVRTC voltage regulator is dedicated for internal use only, and cannot be used to support external loads. An output filtering capacitor must be connected at the VOUT_LDOVRTC pin. Do not connect any other components or external loads to this VOUT_LDOVRTC pin. This voltage regulator is enabled in normal mode or backup mode. The LDOVRTC voltage regulator functions in normal mode when supplied from the main system power rail and is able to supply the input buffers of GPIO3 and GPIO4, the digital components, the crystal, and the RTC calendar module of the TPS6593-Q1 device. The LDOVRTC voltage regulator remains on in BACKUP state when VCCA is below the VCCA_UVLO level, and the backup power source is above the LDOVRTC_UVLO level. Only the 32 kHz crystal and the RTC counter are activated in the BACKUP state. The RTC calendar function remains active in the LP_STANDBY state, but the interrupt functions are reduced to maintaining the wake up functions only. The RTC calendar and interrupt functions are fully activated in the mission states. The customer has the option to enable the shelf mode by setting the LDORTC_DIS bit to 1 while the device is in the MISSION state and the I2C bus is in operation and ramp down VCCA to 0 V immediately after the I2C write has completed. This shelf mode forces the device to skip the BACKUP state and enters the NO SUPPLY state under VCCA_UVLO condition. This mode is useful to prevent the continual draining of the backup power source when the 32 KHz crystal and RTC counter functions are no longer needed. LDO1, LDO2, and LDO3 A 20220110 Added LDO1, LDO2, LDO3 Current Limit descriptionyes The LDO1, LDO2 and LDO3 regulators can deliver up to 500 mA of current, with a configurable output range of 0.6 V to 3.3 V in 50-mV steps. These 3 LDO regulators also support bypass mode, which allows an input voltage at the PVIN_LDOn to show up at the VOUT_LDOn pin. This feature allows the LDOs to be configured as load switches with power sequencing control. Similar to the buck regulators mentioned in , the UV/OV Voltage Monitor of an un-used LDO regulator can also be used to monitor an external voltage rail by connecting the external rail to the VOUT_LDOn pin. The bypass capability to connect the input voltage to the output in bypass mode is supported when the input voltage is within the 1.7 V to 3.5 V range. This bypass capability also allows the LDO to switch from 3.3 V in bypass mode to 1.8 V in LDO mode or from 1.8 V in LDO mode to 3.3 V in bypass mode for an SD card I/O supply. The LDO1, LDO2 and LDO3 regulator include a Current-Limit to protect the internal Power-FET against overcurrent. This Current-Limit has a fixed value between 700 mA and 1800 mA. It is important to wait until the LDO has settled on the target voltage from the previous change when changing the LDO output voltage setting. The worst-case voltage scaling time for LDO1, LDO2, and LDO3 is 63 µs x (7 + the number of 50-mV steps to the new target voltage). #GUID-EC409DDC-2E1D-4E58-8C0F-5BA31078220E/X2414 shows the coding used to select the output voltage for LDO1, LDO2, and LDO3.

This LDO is specifically designed to supply noise sensitive circuits. This supply can be used to power circuits such as PLLs, oscillators, or other analog modules that require low noise on the supply. LDO4 does not support bypass mode. However, if the LDO4 output voltage is not used, the associated UV/OV Voltage Monitor of this regulator can be used as to monitor an external voltage rail by connecting this external voltage rail to the VOUT_LDO4 pin. The LDO4 regulator includes a Current-Limit to protect the internal Power-FET against overcurrent. This Current-Limit has a fixed value between 400 mA and 900 mA. #GUID-7532B08A-787D-48A5-866A-CF9357CABD43/X1331 shows the coding used to select the output voltage for LDO4.

Thermal warning can also be included in the result of the PGOOD monitor if it is not masked. Either voltage and current monitoring or only voltage monitoring can be selected for PGOOD indication. This selection is set by the PGOOD_SEL_BUCKn register bits for each BUCK regulator (select primary phase for multi-phase regulator), and is set by the PGOOD_SEL_LDOn register bits for each LDO regulator. When voltage and current are monitored, an active PGOOD signal active indicates that the regulator output is inside the Power-Good voltage window and that load current is below the current limit. If only voltage is monitored, then the current monitoring is ignored for the PGOOD signal. The PGOOD signal represents the momentary status of the included indications without latching. If the PGOOD signal goes low due to an indicated warning or error condition, the PGOOD signal goes high immediately when the previous indicated warning or error condition is no longer present. The BUCKn_VMON_EN bit enables the overvoltage (OV) , undervoltage (UV) and short-circuit (SC) comparators. The current limit (ILIM) comparator of each BUCK regulator is activated as soon as the corresponding BUCK regulator is enabled. In order to add the current limit indication of a BUCK regulator to the PGOOD signal, the BUCKn_VMON_EN bit of the corresponding BUCK regulator must be set. For LDO regulators, the LDOn_VMON_EN bit enables the OV and UV, short-circuit (SC) comparators. The current limit (ILIM) comparator of each LDO regulator is activated as soon as the corresponding LDO regulator is enabled. In order to add the current limit indication of an LDO to the PGOOD signal, the LDOn_VMON_EN bit of the corresponding LDO regulator must be set. When a BUCK or an LDO is not needed as a regulated output, it can be used as a voltage monitor for an external rail. For BUCK converters, if the BUCKn_VMON_EN bit remains '1' while the BUCKn_EN bit is '0', it can be used as a voltage monitor for an external rail that is connected to the FB_Bn pin of the BUCK regulator. For LDO regulators, if the LDOn_VMON_EN bit remains '1' while the LDOn_EN bit is '0', it can be used as a voltage monitor for an external rail which is connected to the VOUT_LDOn pin. When the voltage monitor for a BUCK or LDO regulator is inactive, the output of the corresponding monitor is automatically masked to prevent it from forcing PGOOD inactive. The masking allows PGOOD to be connected to other open-drain power good signals in the system. The VCCA input voltage monitoring is enabled with VCCA_VMON_EN bit. The monitoring can be enabled by an NVM default setting, that starts the monitoring of the VCCA voltage after the device passes the BOOT BIST state. The reference voltage for the VCCA monitor can be set by the VCCA_PG_SET bit to either 3.3 V or 5 V. The PGOOD_SEL_VCCA register bit selects whether or not the result of the VCCA monitor is included in the PGOOD monitor output signal. An NVM option is available to gate the PGOOD output with the nRSTOUT and the nRSTOUT_SoC signals, the intended reset signals for the safety MCU and the SoC respectively. When PGOOD_SEL_NRSTOUT = '1', the PGOOD pin is gated by the nRSTOUT signal. When PGOOD_SEL_NRSTOUT_SOC = '1', the PGOOD pin is gated by the nRSTOUT_SoC signal. This option allows the PGOOD output to be used as an enable signal for external peripherals. The outputs of the voltage monitors from all the output rails are combined, and PGOOD is active only if all the sources shows active status. The type of output voltage monitoring for PGOOD signal is selected by PGOOD_WINDOW bit. If the bit is 0, only undervoltage is monitored; if the bit is 1, then undervoltage and overvoltage are monitored. The polarity and the output type (push-pull or open-drain) are selected by PGOOD_POL and GPIO9_OD bits. shows the Power-Good generation block diagram, and shows the Power-Good waveforms. PGOOD Block Diagram PGOOD Waveforms The OV and UV threshold of the voltage monitors of the BUCK regulators and the LDO regulators are updated automatically by the digital control block when the output voltage setting changes. When the output voltage of the regulator is increased, the OV threshold is updated at the same time the _VSET of the regulator is changed. The UV threshold is updated after a delay calculated by the delta voltage change and the slew rate setting. When the output voltage is decreased, the UV threshold is updated at the same time the _VSET of the regulator is changed. The OV threshold is updated after a delay calculated by the delta voltage change and the slew rate setting. The OV and UV threshold of the BUCK and LDO output voltage monitors are calculated based on the target output voltage set by the corresponding BUCKn_VSET1, BUCKn_VSET2, or LDOn_VSET registers, and the deviation from the target output voltage set (the voltage window) by the corresponding BUCKn_UV_THR, BUCKn_OV_THR, LDOn_UV_THR, and the LDOn_OV_THR registers. For the OV and UV threshold of BUCK and LDO output monitors to update with the correct timing, the following operating procedures must be followed when updating the _VSET values of the regulators to avoid detection of OV/UV fault: BUCK and LDO regulators must be enabled at the same time as or earlier than as their VMON New voltage level must not be set before the start-up has finished New voltage level must not be set before the previous voltage change (ramp plus settling time) has completed The voltage monitors of unused BUCK or LDO regulators can be used for external supply rails monitoring. In three-phase configuration, the Voltage Monitor of BUCK3 (on FB_B3 pin) becomes a free available resource for monitoring an external supply voltage. In four-phase configuration, the Voltage Monitor of both BUCK3 (on FB_B3 pin) and BUCK4 (on FB_B4 pin) become free available resources for monitoring two external supply voltages.. The target output voltage is set by the corresponding BUCKn_VSET1, BUCKn_VSET2, or LDOn_VSET registers, and the deviation from the target output voltage set (the voltage window) by the corresponding BUCKn_UV_THR, BUCKn_OV_THR, LDOn_UV_THR, and the LDOn_OV_THR registers. Following aspects need to be taken into account if Voltage Monitors of unused BUCK or LDO regulators are used for monitoring external supply rails: For voltage monitors of unused LDO regulators: the voltage level applied at the VOUT_LDOx pin, inclusive expected tolerances, must be below the supply voltage applied at the PVIN_LDOx pin For voltage monitors of unused BUCK and LDO regulators: the maximum nominal supply voltage of the monitored supply rail is 3.3V For voltage monitors of unused BUCK regulators and for voltage monitors of BUCK3 and/or BUCK4 regulators if used in a three-phase or four-phase configuration: the configured values for the BUCKn_VSET and the BUCKn_SLEW_RATE determine the delay-time for the voltage monitoring to become active after the corresponding BUCKn_VMON_EN bit is set. See equation (2) in . If BUCK3 and/or BUCK4 regulators are used in a three-phase or four-phase configuration: even though the values for the BUCK1_VSET and BUCK1_SLEW_RATE bits determine the output voltage and slew-rate of the three-phase or four-phase output rail, the values for BUCK3_VSET respectively BUCK4_VSET and BUCK3_SLEW_RATE respectively BUCK4_SLEW_RATE bits determine the power-good level and the voltage monitoring delay time for the BUCK3 respectively BUCK4 Voltage Monitors. For voltage monitors of unused LDO regulators: the delay-time for the voltage monitoring to become active after the corresponding LDOn_VMON_EN bit is set it 601..606μs. Thermal Monitoring The TPS6593-Q1 device includes several thermal monitoring functions for internal thermal protection of the PMIC. The TPS6593-Q1 device integrates thermal detection modules to monitor the temperature of the die. These modules are placed on opposite sides of the device and close to the LDO and BUCK modules. An over-temperature condition at either module first generates a warning to the system, and if the temperature continues to rise, then a switch-off of the PMIC device can occur before damage to the die. Three thermal protection levels are available. One of these protections is a thermal warning function described in , that sends an interrupt to software. Software is expected to close any noncritical running tasks to reduce power. The second and third protections are the thermal shutdown (TS) function described in , that begins device shutdown orderly or immediately. Thermal monitoring is automatically enabled when one of the BUCK or LDO outputs is enabled within the mission states. The thermal monitoring is deactivated in the LP_STANDBY state, when only the internal regulators are enabled, to minimize the device power consumption. Indication of a thermal warning event is written to the TWARN_INT register. The current consumption of the thermal monitoring can be decreased in the mission states when the low power dissipation is important. If LPM_EN bit is set and the temperature is below thermal warning level in all thermal detection modules, only one thermal detection module is monitored. If the temperature rises in this module, monitoring in all thermal detection modules is started. If the die temperature of the TPS6593-Q1 device continues to rise while the device is in mission state, an TSD_ORD_INT or TSD_IMM_INT interrupt is generated, causing a SEVERE or MODERATE error trigger (respectively) in the state machine. While the sequencing and error handling is NVM memory dependent, TI recommends a sequenced shutdown for MODERATE errors, and an immediate shutdown, using resistive discharging, for SEVERE errors to prevent damage to the device. The system cannot restart until the temperature falls below the thermal warning threshold. Thermal Warning Function The thermal monitor provides a warning to the host processor through the interrupt system when the temperature reaches within a cautionary range. The threshold value must be set to less than the thermal shutdown threshold. The integrated thermal warning function provides the MCU an early warning of over-temperature condition. This monitoring system is connected to the interrupt controller and can send an TWARN_INT interrupt when the temperature is higher than the preset threshold. The TPS6593-Q1 device uses the TWARN_LEVEL register bit to set the thermal warning threshold temperature at 130°C or 140°C. There is no hysteresis for the thermal warning level. When the power-management software triggers an interrupt, immediate action must be taken to reduce the amount of power drawn from the PMIC device (for example, noncritical applications must be closed). Thermal Shutdown The thermal shutdown detector monitors the temperature on the die. If the junction reaches a temperature at which damage can occur, a switch-off transition is initiated and a thermal shutdown event is written into a status register. There are two levels of thermal shutdown threshold. When the die temperature reaches the TSD_orderly level, the TPS6593-Q1 device performs an orderly shutdown of all output power rails. If the die temperature raises rapidly and reaches the TSD_imm level before the orderly shutdown process completes, the TPS6593-Q1 device performs an immediate shutdown with activated pull-down on all output power rails, in order to turn off all of the output power rails as rapidly as possible. After the thermal shutdown takes place, the system cannot restart until the die temperature is below the thermal warning threshold. Backup Supply Power-Path The LDOVRTC is supplied from either the VBACKUP (backup supply from either coin-cell or super-cap) input or VCCA. The power-path is designed to prioritize VCCA to maximize the life of the backup supply. When VCCA drops below the VCCA_UVLO threshold, the device shuts down all rails except the LDOVRTC, and enters the BACKUP mode. At this point, the Backup Supply Power-Path switches to the VBACKUP as the input of LDOVRTC. When the voltage of VCCA returns to level above the VCCA_UVLO threshold level, the power-path switches the input of LDOVRTC back to VCCA. When both the VCCA voltage drop below the VCCA_UVLO threshold, and the VBACKUP voltage drops below 1.7V (RTC_LDO_UVLO threshold), the LDOVRTC is turned OFF and the digital core is reset, which forces the device into the NO SUPPLY state. Note: a backup supply is not required for the device to operate. The device skips the BACKUP state if the VBACKUP pin is grounded. General-Purpose I/Os (GPIO Pins) The TPS6593-Q1 device integrates eleven configurable general-purpose I/Os that are multiplexed with alternative features as listed in For GPIOs characteristics, refer to Electrical Characteristics tables for Digital Input Signal Parameters and Digital Output Signal Parameters. When configured as primary functions, all GPIOs are controlled through the following set of registers bits under the individual GPIOn_CONF register. GPIOn_DEGLITCH_EN: Enables the 8 µs deglitch time for each GPIO pin (input) GPIOn_PU_PD_EN: Enables the internal pull up or pull down resistor connected to each GPIO pin GPIOn_PU_SEL: Selects the pull up or the pull down resistor to be connected when GPIOn_PU_PD_EN = '1'. '1' = pull-up resistor selected, '0' = pull-down resistor selected GPIOn_OD: Configures the GPIO pin (output) as: '1' = open drain, '0' = push-pull GPIOn_DIR: Configures the input or output direction of each GPIO pin Each GPIO event can generate an interrupt on a rising edge, falling edge, or both, configured through the GPIOn_FALL_MASK and the GPIOn_RISE_MASK register bits. A GPIO-interrupt applies when the primary function (general-purpose I/O) has been selected and also for the following alternative functions: nRSTOUT_SOC PGOOD nERR_MCU nERR_SoC TRIG_WDOG DISABLE_WDOG NSLEEP1, NSLEEP2 WKUP1, WKUP2 LP_WKUP1, LP_WKUP2 The GPIOn_SEL[2:0] register bits under the GPIOn_CONF registers control the selection between a primary and an alternative function. When a pre-defined function is selected, some predetermined IO characteristics (such as pullup, pulldown, push-pull or open drain) for the pin are enforced regardless of the settings of the associated GPIO configuration register. Please note that if the GPIOn_SEL[2:0] is changed during device operation, a signal glitch may occur which may cause digital malfunction, especially if it involves a clock signal such as SCL_I2C2, CLK32KOUT, SCL_SPMI, SYNCCLKIN, or SYNCCLKOUT. Please refer to for more detail on the predetermined IO characteristics for each pre-defined digital interface function. All GPIOs can be configured as a wake-up input when it is configured as a WKUP1 or a WKUP2 signal. Only GPIO3 and GPIO4 can be configured as LP_WKUP1 or LP_WKUP2 signal so that they can be used to wake-up the device from LP_STANDBY state. All GPIOs can also be configured as a NSLEEP1 or a NSLEEP2 input. For more information regarding the usage of the NSLEEPx pins and the WKUPx pins, please refer to and . Any of the GPIO pin can also be configured as part of the power-up sequence to enable external devices such as external BUCKs when it is configured as a general-purpose output port. The nINT pin, the EN_DRV pin, the nRSTOUT pin and the GPIO pin assigned as nRSTOUT_SOC have readback monitoring to detect errors on the signals. The monitoring of the EN_DRV pin checks for mismatch in both low and high levels. For the nINT pin, the nRSTOUT pin and the GPIO pin assigned as nRSTOUT_SOC, the readback monitoring only checks for mismatches in the low level, therefore it is allowed to combine these signals with other external pull-down sources. The readback mismatch is continuously monitored without deglitch circuitry during operation, and the monitoring is gated for tgate_readback period when the signal state is changed or when a new function is selected for the GPIO pin with the GPIOn_SEL bits. NINT_READBACK_INT, EN_DRV_READBACK_INT, NRSTOUT_READBACK_INT, and NRSTOUT_SOC_READBACK_INT are the interrupt bits that are set in an event of a readback mismatch for these pins, respectively.All GPIO pin are set to generic input pins with resistive pull-down before NVM memory is loaded during device power up. Therefore, if any GPIOs has external pull-up resistors connecting to a voltage domain that is energized before the NVM memory is loaded, the GPIO pin is pulled high before the configuration for the pin is loaded from the NVM. For GPIO pins with internal pull down enabled, additional leakage current flows into the GPIO pin if this pin is pulled-up to a voltage higher than the voltage level of its output power domain. If the internal pull down must be enabled, please use a resistor divider to divide down the input voltage, or use a series resistor to connect to the input source and ensure the voltage level at the GPIO pin is below the voltage level of its output power domain. nINT, EN_DRV, and nRSTOUT Pins The nINT, EN_DRV and nRSTOUT pin, and the GPIO pin assigned as nRSTOUT_SoC are IO pins with dedicated functions. The nINT pin is the open drain interrupt output pin. More description regarding the function of this pin can be found under . The nRSTOUT pin, together with the GPIO pin assigned as nRSTOUT_SoC, are the system reset pins which can be configured as open-drain or push-pull outputs. These pins stay in the default low state until the PFSM of the TPS6593-Q1 sets the associated control bits NRSTOUT and NRSTOUT_SOC in the register map. These control bits NRSTOUT and NRSTOUT_SOC are set by the PFSM typically after the end of a power-up sequence. At the beginning of a power-down sequence, the PFSM clears these control bits NRSTOUT and NRSTOUT_SOC in order to pull-down the nRSTOUT and nRSTOUT_SoC pins before the ramp-down of the voltage rails. The purpose of the EN_DRV pin is to indicate that the TPS6593-Q1 has entered a safe state. The EN_DRV pin has an internal 10kΩ high-side pull-up to the VCCA supply. The TPS6593-Q1 pulls this EN_DRV pin to the default low state, and releases the pull-down when the MCU sets the ENABLE_DRV bit to '1'. Interrupts The interrupt registers in the device are organized in hierarchical fashion. The interrupts are grouped into the following categories: BUCK ERROR These interrupts indicate over-voltage (OV), under-voltage (UV), short-circuit (SC) and over-current (ILIM) error conditions found on the BUCK regulators . LDO ERROR These interrupts indicate OV, UV, and SC error conditions found on the LDO regulators, as well as OV and UV error conditions found on the VCCA supply. VMON ERROR These interrupts indicate OV and UV error conditions found on the VCCA supply. SEVERE ERROR These errors indicate severe device error conditions, such as thermal shutdown, PFSM sequencing and execution error and VCCA over-voltage, that causes the device to trigger the PFSM to execute immediate shutdown of all digital outputs, external voltage rails and monitors, and proceed to the Safe Recovery State. MODERATE ERROR These interrupts provide warnings to the system to indicate multiple restart attempts from SAFE RECOVERY state exceeding the allowed recovery count, multiple warm-reset executions exceeding the allowed recovery count, detection of long press nPWRON button, SPMI communication error, register CRC error, BIST failure, read-back error on nRSTOUT or nINT pins, or junction temperature reaching orderly shutdown level. These warning causes the device to trigger the PFSM to execute orderly shutdown of all digital outputs, external voltage rails and monitors, and proceed to the SAFE RECOVERY state.The SEVERE ERROR and the MODERATE ERROR are handled in NVM memory but TI requires that the NVM pre-configurable finite state machine (PFSM) settings always follow this described error handling to meet device specifications. MISCELLANEOUS WARNING These interrupts provide information to the system to indicate detection of WDOG or ESM errors, die temperature crossing thermal warning threshold, device passing BIST test, or external sync clock availability. START-UP SOURCE These interrupts provide information to the system on the mechanism that caused the device to start up, which includes FSD, RTC alarm or timer interrupts, the activation of the ENABLE pin or the nPRWON pin button detection. GPIO DETECTION These interrupts indicate a High-Level or Rising-Edge detection, or indicate a Low-Level or Falling-Edge detection at the GPIO1 through GPIO11 pins. FSM ERROR INTERRUPT These interrupts indicate the detection of an error that causes the device mission state changes. All interrupts are logically combined on a single output pin, nINT (active low). The host processor can read the INT_TOP register to find the interrupt registers to find out the source of the interrupt, and write '1' to the corresponding interrupt register bit to clear the interrupt. This mechanism ensures when a new interrupt occurs while the nINT pin is still active, all of the corresponding interrupt register bits retain the interrupt source information until it is cleared by the host. Hierarchical Structure of Interrupt Registers shows the hierarchical structure of the interrupt registers according to the categories described above. The purpose of this register structure is to reduce the number of interrupt register read cycles the host has to perform in order to identify the source of the interrupt. Summary of Interrupt Signals summarizes the trigger and the clearing mechanism for all of the interrupt signals. This table also shows which interrupt sources can be masked by setting the corresponding mask register to '1'. When an interrupt is masked, the interrupt bit is not updated when the associated event occurs, the nINT line is not affected, and the event is not recorded. If an interrupt is masked after the event occurred, the interrupt register bit reflects the event until the bit is cleared. While the event is masked, the interrupt register bit is not over-written when a new event occurs.

The actual results can be configured differently in NVM memory. TI recommends reviewing of the system and device functional safety goal and documentation before deviating from these recommendations. Interrupt is generated during clock detector operation and in case clock is not available when clock detector is enabled. This event does not occur if RECOV_CNT_THR = 0, even though RECOV_CNT continues to accumulate and increase, and eventually saturates when it reaches the maximum count of 15. Due to a digital logic errata in the device, a write or read SPI command which coincide with the rising edge of the CS signal may not cause the COMM_FRM_ERR_INT interrupt. I2C1, I2C2, or SPI address error only occur in safety applications if the interface CRC feature is enabled, when both I2C1_SPI_CRC_EN and I2C2_CRC_EN are set to '1'. RTC General Description The RTC is driven by the 32-kHz oscillator and it provides the alarm and time-keeping functions. The main functions of the RTC block are: Time information (seconds, minutes, and hours) in binary-coded decimal (BCD) code Calendar information (day, month, year, and day of the week) in BCD code up to year 2099 Configurable interrupts generation; the RTC can generate two types interrupts which can be enabled and masked individually: Timer interrupts periodically (1-second, 1-minute, 1-hour, or 1-day periods) Alarm interrupt at a precise time of the day (alarm function) Oscillator frequency calibration and time correction with 1/32768 resolution shows the RTC block diagram. RTC Block Diagram Time Calendar Registers All the time and calendar information is available in the time calendar (TC) dedicated registers: SECONDS_REG, MINUTES_REG, HOURS_REG, DAYS_REG, WEEKS_REG, MONTHS_REG, and YEARS_REG. The TC register values are written in BCD code. Year data ranges from 00 to 99. Leap Year = Year divisible by four (2000, 2004, 2008, 2012, and so on) Common Year = Other years Month data ranges from 01 to 12. Day value ranges: 1 to 31 when months are 1, 3, 5, 7, 8, 10, 12 1 to 30 when months are 4, 6, 9, 11 1 to 29 when month is 2 and year is a leap year 1 to 28 when month is 2 and year is a common year Weekday value ranges from 0 to 6. Hour value ranges from 0 to 23 in 24-hour mode and ranges from 1 to 12 in AM or PM mode. Minutes value ranges from 0 to 59. Seconds value ranges from 0 to 59. Example: Time is 10H54M36S PM (PM_AM mode set), 2008 September 5; previous registers values are listed in #GUID-D55684DC-1A31-4EAF-B994-D540AFAEA45A/SWCS0959413: RTC Time Calendar Registers Example REGISTER CONTENT RTC_SECONDS 0x36 RTC_MINTURES 0x54 RTC_HOURS 0x10 RTC_DAYS 0x05 RTC_MONTHS 0x09 RTC_YEARS 0x08 RTC_WEEKS 0x06 The user can round to the closest minute, by setting the ROUND_30S register bit in the RTC_CTRL_REG register. TC values are set to the closest minute value at the next second. The ROUND_30S bit is automatically cleared when the rounding time is performed. Example: If current time is 10H59M45S, round operation changes time to 11H00M00S If current time is 10H59M29S, round operation changes time to 10H59M00S TC Registers Read Access TC register read access can be done in two ways: A direct read to the TC registers. In this case, there can be a discrepancy between the final time read and the real time because the RTC keeps running because some of the registers can toggle in between register accesses. Software must manage the register change during the reading. Read access to shadowed TC registers. These registers are at the same addresses as the normal TC registers. They are selected by setting the GET_TIME bit in the RTC_CTRL_REG register. When this bit is set, the content of all TC registers is transferred into shadow registers so they represent a coherent timestamp, avoiding any possible discrepancy between them. When processing the read accesses to the TC registers, the value of the shadowed TC registers is returned so it is completely transparent in terms of register access. TC Registers Write Access TC registers write accesses can be done while RTC is stopped. MCU can stop the RTC by the clearing the STOP_RTC bit of the control register and checking the RUN bit of the status to be sure that RTC is frozen. MCU then updates the TC values and restarts the RTC by setting the STOP_RTC bit, which ensures that the final written values are aligned with the targeted values. RTC Alarm RTC alarm registers (ALARM_SECONDS_REG, ALARM_MINUTES_REG, ALARM_HOURS_REG, ALARM_DAYS_REG, ALARM_MONTHS_REG, and ALARM_YEARS_REG) are used to set the alarm time or date to the corresponding generated ALARM interrupts. See for how these register values are written in BCD code, with the same data range as described for the TC registers. RTC Interrupts The RTC supports two types of interrupts: ALARM interrupt. This interrupt is generated when the configured date or time in the corresponding ALARM registers is reached. This interrupt is activated and deactivated by setting the IT_ALARM bit. It is important to set the IT_ALARM = 0 to deactivate the alarm interrupt prior to configuring the ALARM registers to prevent the interrupt from mis-firing. TIMER interrupt. This interrupt is generated when the periodic time (day, hour, minute, second) set in the EVERY bits of the RTC_INTERRUPTS register is reached. The first of the periodic interrupt occurs when the RTC counter reaches the next day, hour, minute, or second counter value. For example, if a timer interrupt is set for every hour at 2:59 AM, the first interrupt occurs at 3:00 AM instead of 3:59 AM. This interrupt is activated and deactivated by setting the IT_TIMER bit. It is important to set the IT_TIMER = 0 to disable the timer interrupt prior to configuring the periodic time value to prevent the interrupt from mis-firing. Both types of the RTC interrupts can be used to wake-up the device from the STANDBY state or the LP_STANDBY state when they are not masked. RTC 32-kHz Oscillator Drift Compensation The RTC_COMP_MSB_REG and RTC_COMP_LSB_REG registers are used to compensate for any inaccuracy of the 32-kHz clock output from the 32-kHz crystal oscillator. To compensate for any inaccuracy, MCU must perform an external calibration of the oscillator frequency by calculating the needed drift compensation compared to one hour time-period, and load the compensation registers with the drift compensation value. The compensation mechanism is enabled by the AUTO_COMP_EN bit in the RTC_CTRL_REG register. The compensation process happens after the first second of each hour. The time between second 1 and second 2 (T_ADJ) is adjusted based on the settings of the two RTC_COMP_MSB_REG and RTC_COMP_LSB_REG registers. These two registers form a 16-bit, 2 s complement value COMP_REG (from –32767 to 32767) that is subtracted from the 32-kHz counter as per the following formula to adjust the length of T_ADJ: (32768 - COMP_REG) / 32768. Therefore, this compensation mechanism can adjust the compensation with a 1/32768-second time-unit accuracy per hour and up to 1 second per hour. Software must ensure that these registers are updated before each compensation process (there is no hardware protection). For example, software can load the compensation value into these registers after each hour event, during second 0 to second 1, just before the compensation period, happening from second 1 to second 2. If the SET_32_COUNTER bit in the RTC_CTRL_REG register is set to '1', the internal 32-kHz counter is pre-loaded with the content of the RTC_COMP_MSB_REG and RTC_COMP_LSB_REG registers. This preloading of the internal 32-kHz counter can only be done when the RTC is stopped. shows the RTC compensation scheduling. RTC Compensation Scheduling Watchdog (WDOG) A 20220110 Watchdog (WDOG): added Q&A (question an answer) modeyes The watchdog monitors the correct operation of the MCU. This watchdog requires specific messages from the MCU in specific time intervals to detect correct operation of the MCU. The MCU can control the logic-level of the EN_DRV pin when the watchdog detects correct operation of the MCU. When the watchdog detects an incorrect operation of the MCU, the TPS6593-Q1 device pulls the EN_DRV pin low . This EN_DRV pin can be used in the application as a control-signal to deactivate the power output stages, for example a motor driver, in case of incorrect operation of the MCU. The watchdog has two different modes that are defined as follows: Trigger mode In trigger mode, the MCU applies a pulse signal with a minimum pulse width of tWD_pulse on the pre-assigned GPIO input pin to send the required watchdog trigger. To select this mode, the MCU must clear bit WD_MODE_SELECT. Watchdog Trigger Mode provides more details. Q&A (question and answer) mode In Q&A mode, the MCU sends watchdog answers through the I2C1 bus , I2C2 bus or SPI bus. (Which of these communication busses is to be used depends on the NVM configuration. Please refer to the user's guide of the orderable part number for further details). To select this mode, the MCU must set bit WD_MODE_SELECT. Watchdog Question-Answer Mode provides more details. Watchdog Fail Counter and Status The watchdog includes a watchdog fail counter WD_FAIL_CNT[3:0] that increments because of bad events or decrements because of good events. Furthermore, the watchdog includes two configurable thresholds: Fail-threshold (configurable through bits WD_FAIL_TH[2:0]) Reset-threshold (configurable through bits WD_RST_TH[2:0]) When the WD_FAIL_CNT[3:0] counter value is less than or equal to the configured Watchdog-Fail threshold (WD_FAIL_TH[2:0]) and bit WD_FIRST_OK=1, the MCU can set the ENABLE_DRV bit when no other error-flags are set. When the WD_FAIL_CNT[3:0] counter value is greater than the configured Watchdog-Fail threshold (WD_FAIL_CNT[3:0] > WD_FAIL_TH[2:0]), the device clears the ENABLE_DRV bit, sets the error-flag WD_FAIL_INT, and pulls the nINT pin low. When the WD_FAIL_CNT[3:0] counter value is greater than the configured Watchdog-Fail plus Watchdog-Reset threshold (WD_FAIL_CNT[3:0] > (WD_FAIL_TH[2:0] + WD_RST_TH[2:0])) and the watchdog-reset function is enabled (configuration bit WD_RST_EN=1), the device generates a WD_ERROR trigger in the state machine (see PFSM Trigger Selections) and sets the error-flag WD_RST_INT, and pulls the nINT pin low. Unless described otherwise in the user's guide of the orderable part number, this WD_ERROR trigger in the state machine causes the TPS6593-Q1 to execute a warm-reset, during which the nRSTOUT pin pulled low, and released after a pre-configured delay time. The device clears the WD_FAIL_CNT[3:0] each time the watchdog enters the Long Window. The status bits WD_FAIL_INT and WD_RST_INT are latched until the MCU writes a ‘1’ to these bits. Overview of Watchdog Fail Counter Value Ranges and Corresponding Device Status gives an overview of the Watchdog Fail Counter value ranges and the corresponding device status. Overview of Watchdog Fail Counter Value Ranges and Corresponding Device Status Watchdog Fail Counter value WD_FAIL_CNT[3:0] Device Status WD_FAIL_CNT[3:0] ≤ WD_FAIL_TH[2:0] MCU can set the ENABLE_DRV bit if WD_FIRST_OK=1 and no other error-flags are set. WD_FAIL_TH[2:0] < WD_FAIL_CNT[3:0] ≤ (WD_FAIL_TH[2:0] + WD_RST_TH[2:0]) The device sets error-flag WD_FAIL_INT and pulls the nINT pin low. Furthermore, , the device clears the ENABLE_DRV bit. WD_FAIL_CNT[3:0] > (WD_FAIL_TH[2:0] + WD_RST_TH[2:0]) If configuration bit WD_RST_EN=1, device generates WD_ERROR trigger in the state machine and reacts as defined in the PFSM, sets the error-flag WD_RST_INT, and pulls the nINT pin low. See Summary of Interrupt Signals for the interrupt handling of WD_RST. The WD_FAIL_CNT[3:0] counter responds as follows: When the Watchdog is in the Long-Window, the WD_FAIL_CNT[3:0] is cleared to 4’b0000 A good event decrements the WD_FAIL_CNT[3:0] by one before the start of the next Window-1 A bad event increments the WD_FAIL_CNT[3:0] by one before the start of the next Window-1 Refer to Watchdog Trigger Mode and Watchdog Q&A Related Definitions respectively for definitions of good events and bad events. Watchdog Start-Up and Configuration When the device releases the nRSTOUT pin, the watchdog starts with the Long Window. This Long Window has a time interval (tLONG_WINDOW) with a default value set in bits WD_LONGWIN[7:0]. As long as the watchdog is in the Long Window, the MCU can configure the watchdog through the following register bits: WD_EN to enable or disable the watchdog WD_LONGWIN[7:0] to increase the duration of the Long-Window time-interval WD_MODE_SELECT to select the Watchdog mode (Trigger mode or Q&A Mode) WD_PWRHOLD to activate the Watchdog Disable function (more detail in ) WD_RETURN_LONGWIN to configure whether to return to Long-Window or continue to the next sequence after the completion of the current watchdog sequence (more detail in ) WD_WIN1[6:0] to configure the duration of the Window-1 time-interval WD_WIN2[6:0] to configure the duration of the Window-2 time-interval WD_RST_EN to enable or disable the watchdog-reset function WD_FAIL_TH[2:0] to configure the Watchdog-Fail threshold WD_RST_TH[2:0] to configure the Watchdog-Reset threshold WD_QA_FDBK[1:0] to configure the settings for the reference answer-generation WD_QA_LFSR[1:0] to configure the settings for the question-generation WD_QUESTION_SEED[3:0] to configure the starting-point for the 1st question-generation The device keeps the above register bit values configured by the MCU as long as the device is powered. The MCU can configure the time interval of the Long Window (tLONG_WINDOW) with the WD_LONGWIN[7:0] bits. The WD_LONGWIN[7:0] bits are defined as: 0x00: 80 ms 0x01 - 0x40: 125 ms to 8 sec, in 125-ms steps 0x41 - 0xFF: 12 sec to 772 sec, in 4-sec steps Use #GUID-349299FD-F71B-4E28-A307-921903D70A3E/SLVSE828888 and #GUID-349299FD-F71B-4E28-A307-921903D70A3E/SLVSE822625 to calculate the minimum and maximum values for the Long Window (tLONG_WINDOW) time interval when WD_LONGWIN[7:0] > 0x00: tLONG_WINDOW_MIN = WD_LONGWIN[7:0] × 0.95 tLONG_WINDOW_MAX = WD_LONGWIN[7:0] × 1.05 If the MCU software changes the duration of the Long-Window to an interval shorter than the time in which the watchdog has been in the Long-Window, the time-out function of the Long-Window does no longer operate. When the MCU clears bit WD_EN, the watchdog goes out of the Long Window and disables the watchdog. When the watchdog is deactivated in this way, the MCU can set bit WD_EN back to ‘1’ to enable the watchdog again, and the MCU can control the ENABLE_DRV bit when no other error-flags are set. The MCU must clear bit WD_PWRHOLD before setting bit WD_EN back to ‘1’ to start the watchdog in Long Window. The watchdog locks the following configuration register bits when it goes out of the Long Window and starts the first watchdog sequence: WD_WIN1[6:0] WD_WIN2[6:0] WD_LONGWIN[7:0] WD_MODE_SELECT WD_QA_FDBK[1:0], WD_QA_LFSR[1:0] and WD_QUESTION_SEED[3:0] WD_RST_EN, WD_EN, WD_FAIL_TH[2:0] and WD_RST_TH[2:0] MCU to Watchdog Synchronization In order to go out of the Long Window and start the first watchdog sequence, the MCU must do the following before elapse of the Long Window time interval: Clear bits WD_PWRHOLD (more detail in ) Apply a pulse signal with a minimum pulse-width tWD_pulse on the pre-assigned GPIO pin in the case the watchdog is configured for Trigger mode, or Write four times to WD_ANSWER[7:0] in the case the watchdog is configured for Q&A mode When the MCU fails to get the watchdog out of the Long Window before the configured Long Window time interval (tLONG_WINDOW) elapses, the device goes through a warm reset, and sets the WD_LONGWIN_TIMEOUT_INT. This bit latched until the MCU writes a ‘1’ to clear it. Watchdog Disable Function The watchdog in the TPS6593-Q1 device has a Watchdog Disable function to prevent an unwanted MCU reset in case the MCU is un-programmed or needs to be reprogrammed. In order to activate this Watchdog Disable function for an un-programmed MCU, DISABLE_WDOG pin must be asserted to a logic-high level for a time-interval longer than tWD_DIS prior to the moment the device releases the nRSTOUT pin. If the Watchdog Disable function is activated in this way, the device sets bit WD_PWRHOLD to keep the watchdog in the Long Window. The watchdog stays in the Long Window until the MCU clears the WD_PWRHOLD bit. In case the MCU needs to be reprogrammed while the watchdog monitors the correct operation of the MCU, the MCU can set bit WD_RETURN_LONGWIN to put the watchdog back in the Long Window. When the MCU set this bit, the watchdog returns to the Long Window after the current Watchdog Sequence completes. In order to make the watchdog stay in the Long Window as long as needed the MCU can either re-configure the Long Window (tLONG_WINDOW) time interval, or set the WD_PWRHOLD bit. Once the MCU starts the first watchdog sequence (as described in ), the MCU must clear bit WD_RETURN_LONGWIN before the end of the first watchdog sequence in order to continue the watchdog sequence operation. Watchdog Sequence Once the watchdog is out of the Long Window, each watchdog sequence starts with a Window-1 followed by a Window-2. The watchdog ends the current sequence and after one 20-MHz system clock cycle starts a next sequence when one of the events below occurs: The configured Window-2 time period elapses The watchdog detects a pulse signal with a minimum pulse-width tWD_pulse on the pre-assigned GPIO pin if the watchdog is used in Trigger mode The watchdog detects four times a write access to WD_ANSWER[7:0] in case the watchdog is used in Q&A mode The MCU can configure the time periods of the Window-1 (tWINDOW1) and Window-2 (tWINDOW2) with the bits WD_WIN1[6:0] and WD_WIN2[6:0] respectively, before starting the sequence. Use #GUID-601CEE28-A758-488E-9836-FEEC1D7197D3/SLVSE822895 and #GUID-601CEE28-A758-488E-9836-FEEC1D7197D3/SLVSE828785 to calculate the minimum and maximum values for the tWINDOW1 time interval. tWINDOW1_MIN = (WD_WIN1[6:0] + 1) × 0.55 × 0.95 ms tWINDOW1_MAX = (WD_WIN1[6:0] + 1) × 0.55 × 1.05 ms Use #GUID-601CEE28-A758-488E-9836-FEEC1D7197D3/SLVSE824341 and #GUID-601CEE28-A758-488E-9836-FEEC1D7197D3/SLVSE822158 to calculate the minimum and maximum values for the tWINDOW-2 time interval. tWINDOW2_MIN = (WD_WIN2[6:0] + 1) × 0.55 × 0.95 ms tWINDOW2_MAX = (WD_WIN2[6:0] + 1) × 0.55 × 1.05 ms Watchdog Trigger Mode When the TPS6593-Q1 device is configured to use the Watchdog Trigger Mode, the watchdog receives the watchdog-triggers from the MCU on the pre-assigned GPIO pin . A rising edge on this , followed by a stable logic-high level on that pin for more than the maximum pulse time, tWD_pulse(max), is a watchdog-trigger. The watchdog uses a deglitch filter with a tWD_pulse filter time and the internal 20-MHz system clock to create the internally-generated trigger pulse from the watchdog-trigger on the pre-assigned GPIO pin . The watchdog detects a good event when the watchdog-trigger comes in Window-2. The rising edge of the watchdog-trigger on the pre-assigned GPIO pin must occur for at least the tWD_pulse time before the end of Window-2 to generate such a good event. The watchdog detects a bad event when one of the following events occurs: The watchdog-trigger comes in Window-1. The rising edge of the watchdog-trigger on the pre-assigned GPIO pin must occur for at least the tWD_pulse time before the end of Window-1 to generate such a bad event. In case of this bad event, the device sets bits WD_TRIG_EARLY and WD_BAD_EVENT. No watchdog-trigger comes in Window-2. In case of this bad event (also referred to as time-out event), the device sets bits WD_TIMEOUT and WD_BAD_EVENT. Please consider that the minimum WD-pulse duration needs to meet the maximum deglitch time tWD_pulse (max). The status bit WD_BAD_EVENT is read-only. The watchdog clears the WD_BAD_EVENT status bit at the end of the watchdog-sequence. WatchDog Flow Chart and Timing Diagrams in Trigger Mode shows the flow-chart of the watchdog in Trigger mode.

Watchdog Question-Answer Mode A 20220110 Added Section:Watchdog Question-Answer Modeyes When the TPS6593-Q1 device is configured to use the Watchdog Question Answer mode, the watchdog requires specific messages from the MCU in specific time intervals to detect correct operation of the MCU. The device provides a question for the MCU in WD_QUESTION[3:0] during operation. The MCU performs a fixed series of arithmetic operations on this question to calculate the required 32-bit answer. This answer is split into four answer bytes: Answer-3, Answer-2, Answer-1, and Answer-0. The MCU writes these answer bytes one byte at a time into WD_ANSWER[7:0] from the SPI or the dedicated I2C2 interface, mapped to GPIO1 and GPIO2 pins. A good event occurs when the MCU sends the correct answer-bytes calculated for the current question in the correct watchdog window and in the correct sequence. A bad event occurs when one of the events that follows occur: The MCU sends the correct answer-bytes, but not in the correct watchdog window. The MCU sends incorrect answer-bytes. The MCU returns correct answer-bytes, but in the incorrect sequence. If the MCU stops providing answer-bytes for the duration of the watchdog time-period, the watchdog detects a time-out event. This time-out event sets the WD_TIMEOUT status bit, increments the WD_FAIL_CNT[3:0] counter, and starts a new watchdog sequence. Watchdog Q&A Related Definitions A question and answer are defined as follows: Question A question is a 4-bit word (see ). The watchdog provides the question to the MCU when the MCU reads the WD_QUESTION[3:0] bits. The MCU can request each new question at the start of the watchdog sequence, but this is not required to calculate the answer. The MCU can also have a software implementation that generates the question according the circuit shown in . Nevertheless, the answer and therefore the answer-bytes are always based on the question generated inside the watchdog of the device. So, if the MCU generates an incorrect question and gives answer-bytes calculated from this incorrect question, the watchdog detects a bad event Answer An answer is a 32-bit word that is split into four answer bytes: Answer-3, Answer-2, Answer-1, and Answer-0. The watchdog receives an answer-byte when the MCU writes to the WD_ANSWER[7:0] bits. For each question, the watchdog requires four correct answer-bytes from the MCU in the correct timing and order (Answer-3, Answer-2, and Answer-1 in Window 1 in the correct sequence, and Answer-0 in Window 2) to detect a good event. The watchdog sequence in Q&A mode ends after the MCU writes the fourth answer byte (Answer-0), or after a time-out event when the Window-2 time-interval elapses. Watchdog Sequence in Q&A Mode The register WD_QUESTION_ANSW_CNT has following bits: Bit 6: Reserved Bit 5-4: WD_ANSW_CNT. These bits give the number for the next expected answer-byte Bit 3-0: WD_QUESTION. These bits give the value of the current generated question (1) For the question generation, the MCU is not required to read the question. The MCU can give correct answer-bytes Answer-3, Answer-2, Answer-1 as soon as Window-1 starts. The next watchdog sequence always starts in 1 system clock cycle after the watchdog receives the final Answer-0. (2) The MCU can put other I2C or SPI commands in-between the write-commands to WD_ANSWER[7:0] (even re-requesting the question). The insertion of other commands in-between the write-commands to WD_ANSWER[7:0] has no influence on the detection of a good event, as long as the three correct answer-bytes in Window-1 are in the correct sequence, and the fourth correct answer-byte is provided before the configured Window-2 time-interval elapses. Question Generation The watchdog uses a 4-bit question counter (QST_CNT[3:0] bits in ), and a 4-bit Markov chain to generate a 4-bit question. The MCU can read this question in the WD_QUESTION[3:0] bits. The watchdog generates a new question when the question counter increments, which only occurs when the watchdog detects a good event. The watchdog does not generate a new question when it detects a bad event or a time-out event. The question-counter provides a clock pulse to the Markov chain when it transitions from 4’b1111 to 4’b0000. The question counter and the Markov chain are set to the default value of 4’b0000 when the watchdog goes out of the Long Window. The Question-Generator is only re-initialized (starting with question 0000) at device power-up. In following situations, the MCU software needs to read the current question in order to synchronize with the Question-Generator: After MCU re-boot from a warm-reset After MCU software sets bit WD_RETURN_LONGWIN=1 to put the Watchdog back into Long Window After MCU wrote WD_EN=0, then reenable Watchdog again with WD_EN=1 shows the logic combination for the WD_QUESTION[3:0] generation. shows how the logic combination of the question-counter with the WD_ANSW_CNT[1:0] status bits generates the reference answer-bytes. Watchdog Question Generation (1) If the current value for bits (x1, x2, x3, x4) is 4'b0000, the next value for these bits (x1, x2, x3, x4) is 4'b0001, and all further question generation begins from this value. Watchdog Reference Answer Calculation Answer Comparison The 2-bit, watchdog-answer counter, WD_ANSW_CNT[1:0], counts the number of received answer-bytes and controls the generation of the reference answer-byte as shown in . At the start of each watchdog sequence, the default value of the WD_ANSW_CNT[1:0] counter is 2’b11 to indicate that the watchdog expects the MCU to write the correct Answer-3 in WD_ANSWER[7:0]. The device sets the WD_ANSW_ERR status bit as soon as one answer byte is not correct. The device clears this status bit only if the MCU writes a ‘1’ to this bit. Sequence of the 2-bit Watchdog Answer Counter The sequence of the 2-bit, watchdog answer-counter is as follows for each counter value: WD_ANSW_CNT[1:0] = 2‘b11: The watchdog calculates the reference Answer-3. A write access occurs. The MCU writes the Answer-3 byte in WD_ANSWER[7:0]. The watchdog compares the reference Answer-3 with the Answer-3 byte in WD_ANSWER[7:0]. The watchdog decrements the WD_ANSW_CNT[1:0] bits to 2b‘10 and sets the WD_ANSW_ERR status bit to 1 if the Answer-3 byte was incorrect. WD_ANSW_CNT[1:0] = 2b‘10: The watchdog calculates the reference Answer-2. A write access occurs. The MCU writes the Answer-2 byte in WD_ANSWER[7:0]. The watchdog compares the reference Answer-2 with the Answer-2 byte in WD_ANSWER[7:0].. The watchdog decrements the WD_ANSW_CNT[1:0] bits to 2b‘01 and sets the WD_ANSW_ERR status bit to 1 if the Answer-2 byte was incorrect. WD_ANSW_CNT[1:0] = 2b‘01: The watchdog calculates the reference Answer-1. A write access occurs. The MCU writes the Answer-1 byte in WD_ANSWER[7:0]. The watchdog compares the reference Answer-1 with the Answer-1 byte in WD_ANSWER[7:0].. The watchdog decrements the WD_ANSW_CNT[1:0] bits to 2b‘00 and sets the WD_ANSW_ERR status bit to 1 if the Answer-1 byte was incorrect. WD_ANSW_CNT[1:0] = 2b‘00: The watchdog calculates the reference Answer-0. A write access occurs. The MCU writes the Answer-0 byte in WD_ANSWER[7:0]. The watchdog compares the reference Answer-0 with the Answer-0 byte in WD_ANSWER[7:0]. The watchdog sets the WD_ANSW_ERR status bit to 1 if the Answer-0 byte was incorrect. The watchdog starts a new watchdog sequence and sets the WD_ANSW_CNT[1:0] to 2‘b11’. The MCU needs to clear the bit by writing a '1' to the WD_ANSW_ERR bit.

After such a good event, following events occur: The WD_FAIL_CNT[2:0] counter decrements by one at the end of the watchdog-sequence. The question-counter increments by one and the watchdog generates a new question. A bad event occurs when all answer-bytes are correct in value but not in correct timing. After such a bad event, following events occur: The WD_SEQ_ERR and WD_BAD_EVENT status bits are set if Window-1 time-interval elapses before watchdog has received Answer-3, Answer-2 and Answer-1. The WD_ANSW_EARLY and WD_BAD_EVENT status bits are set if watchdog receives all four answers in Window-1. The WD_FAIL_CNT[2:0] counter increments by one at the end of the watchdog-sequence. The question-counter does not change, and hence the watchdog does not generate a new question. A bad event occurs when one or more of the answer-bytes are not correct in value but in correct timing. After such a bad event, following events occur: The WD_ANSW_ERR and WD_BAD_EVENT status bits are set as soon as the watchdog detects an incorrect answer-byte. The WD_FAIL_CNT[2:0] counter increments by one at the end of the watchdog-sequence. The question-counter does not change, and hence the watchdog does not generate a new question. A bad event occurs when one or more of the answer-bytes are not correct in value and not in correct timing. After such a bad event, following events occur: The WD_ANSW_ERR and WD_BAD_EVENT status bits are set as soon as the watchdog detects an incorrect answer-byte. The WD_SEQ_ERR and WD_BAD_EVENT status bits are set if Window-1 time-interval elapses before watchdog has received Answer-3, Answer-2 and Answer-1. The WD_ANSW_EARLY and WD_BAD_EVENT status bits are set if watchdog receives all four answer-bytes in Window-1. The WD_FAIL_CNT[2:0] counter increments by one at the end of the watchdog-sequence. The question-counter does not change, and hence the watchdog does not generate a new question. A time-out event occurs when the device receives less than 4 answer-bytes before Window-2 time-interval elapses. After a time-out event occurs, following events occur: WD_SEQ_ERR and WD_BAD_EVENT status bits are set if Window-1 time-interval elapses before watchdog has received Answer-3, Answer-2 and Answer-1. The WD_TIMEOUT and WD_BAD_EVENT status bits are set at the end of the watchdog-sequence. The WD_FAIL_CNT[2:0] counter increments by one at the end of the watchdog-sequence. The question-counter does not change, and hence the watchdog does not generate a new question. The status bit WD_BAD_EVENT is read-only. The watchdog clears the WD_BAD_EVENT status bit at the end of the watchdog-sequence. The status bits WD_SEQ_ERR, WD_ANSW_EARLY, and WD_TIMEOUT are latched until the MCU writes a ‘1’ to these bits. If one or more of these status bits are set, the watchdog can still detect a good event in the next watchdog-sequence. These status bits are read-only. The watchdog clears the WD_BAD_EVENT status bit at the end of the watchdog-sequence. shows the flow-chart of the watchdog in Q&A mode.

Signal Monitor (ESM)yes The TPS6593-Q1 device has two error signal monitor (ESMs): one ESM_MCU to monitor the MCU error output signal at the nERR_MCU input pin, and one ESM_SoC to monitor the SoC error output signal at the nERR_SoC input pin. At device start-up, the ESM_MCU and ESM_SoC can be enabled or deactivated through configuration bits ESM_MCU_EN and ESM_SOC_EN. The values for these configuration bits are stored in the NVM memory of the device. To start the enabled ESM, the MCU sets the start bits ESM_MCU_START or ESM_SOC_START for the corresponding ESM through software after the system is powered up and the initial software configuration is completed. If the MCU clears a start bit, the ESM stops monitoring its input pin. The MCU can set the ENABLE_DRV bit only when the MCU has either started or deactivated the ESM. When the corresponding ESM is started, the following configuration registers are write protected and can only be read: Configuration registers write-protected by the ESM_MCU_START register bit: ESM_MCU_DELAY1_REG ESM_MCU_DELAY2_REG ESM_MCU_MODE_CFG ESM_MCU_HMAX_REG ESM_MCU_HMIN_REG ESM_MCU_LMAX_REG ESM_MCU_LMIN_REG Configuration registers write-protected by the ESM_SOC_START register bit: ESM_SOC_DELAY1_REG ESM_SOC_DELAY2_REG ESM_SOC_MODE_CFG ESM_SOC_HMAX_REG ESM_SOC_HMIN_REG ESM_SOC_LMAX_REG ESM_SOC_LMIN_REG The ESM uses a deglitch-filter with deglitch-time tdegl_ESMx to monitor its related input pin. The MCU can configure the ESM in two different modes that are defined as follows: Level Mode the ESM detects an ESM-error when the input pin remains low for a time equal to or longer than the deglitch-time tdegl_ESMx. To select this mode for the ESM_MCU, the MCU must clear bit ESM_MCU_MODE. To select this mode for the ESM_SoC, the MCU must clear bit ESM_SOC_MODE. See for further detail. PWM Mode the ESM monitors a PWM signal at its input pin. The ESM detects a bad-event when the frequency or duty cycle of the PWM input signal deviates from the expected signal. The ESM detects a good-event when the frequency and duty cycle of the PWM signal match with the expected signal for one signal period. The ESM has an error-counter (ESM_MCU_ERR_CNT[4:0] or ESM_SOC_ERR_CNT[4:0]), which increments with +2 after each bad-event, and decrements with -1 after each good-event. The ESM detects an ESM-error when the error-counter value is more than its related threshold value. To select this mode for the ESM_MCU, the MCU must set bit ESM_MCU_MODE. To select this mode for the ESM_SoC, the MCU must set bit ESM_SOC_MODE. See for further details. The MCU can configure each ESM as long as its related start bit is cleared to 0 (bit ESM_MCU_START or ESM_SOC_START). As soon as the MCU sets a start bit, the device sets a write-protection on the configuration registers of the related ESM except the related start bits ESM_MCU_START and ESM_SOC_START. ESM Error-Handling Procedure Each ESM has two of its own configurable delay-timers that are reset when the device clears the respective ESM_x_START bit. Below steps describe the procedure through which the ESM goes in case it detects an ESM-error: If the respective mask bit ESM_x_PIN_MASK=0, the device sets interrupt bit ESM_MCU_PIN_INT or ESM_SOC_PIN_INT, and pulls the nINT pin low. The ESM starts the delay-1 timer (configurable through related ESM_MCU_DELAY1[7:0] or ESM_SOC_DELAY1[7:0] bits). If the ESM-error is no longer present and MCU has cleared the related interrupt bit ESM_MCU_PIN_INT or ESM_SOC_PIN_INT before the delay-1 timer elapses, the device releases the nINTpin, the ESM resets the delay-1 and delay-2 timers and continues to monitor its input pin. If the ESM-error is still present, or if MCU has not cleared the related interrupt bit ESM_MCU_PIN_INT or ESM_SOC_PIN_INT, and the delay-1 timer elapses, then the ESM clears the ENABLE_DRV bit if bit ESM_MCU_ENDRV=1 or if bit ESM_SOC_ENDRV=1. If the delay-2 timer (configurable through related ESM_MCU_DELAY2[7:0] or ESM_SOC_DELAY2[7:0] bits) is set to 0, then the ESM skips steps 6 of this list, and performs step 7. If the delay-2 timer is not set to 0, then: ESM starts the delay-2 timer, If ESM_MCU_FAIL_MASK = 0, the device sets interrupt bit ESM_MCU_FAIL_INT and pulls the nINT pin low and starts the delay-2 timer. If ESM_SOC_FAIL_MASK = 0, the device sets interrupt bit ESM_SOC_FAIL_INT, pulls the nINT pin low and starts the delay-2 timer. If the ESM-error is no longer present and the MCU has cleared the related interrupt bits listed below before the delay-2 timer elapses, the device releases the nINTpin, the ESM resets the delay-1 and delay-2 timers and continues to monitor its input pin: ESM_MCU_PIN_INT (and ESM_MCU_FAIL_INT if set in step 6), or ESM_SOC_PIN_INT (and ESM_SOC_FAIL_INT if set in step 6) If the ESM-error is still present, or if MCU has not cleared the related interrupt bits ESM_MCU_PIN_INT and ESM_MCU_FAIL_INT , or ESM_SOC_PIN_INT and ESM_SOC_FAIL_INT, and the delay-2 timer elapses, then : For ESM_MCU, the device: clears the ESM_MCU_START BIT sets interrupt bits ESM_MCU_FAIL_INT and ESM_MCU_RST_INT, which the device handles as an ESM_MCU_RST trigger for FSM, described in Summary of Interrupt Signals After this trigger handling completes, the device re-initializes the ESM_MCU For ESM_SoC, the device: clears the ESM_SOC_START bit sets interrupt bits ESM_SOC_FAIL_INT and ESM_SOC_RST_INT, which the device handles as an ESM_SOC_RST trigger for FSM, described in Summary of Interrupt Signals After this trigger handling completes, the device re-initializes the ESM_SoC ESM_MCU_DELAY1[7:0] and ESM_SOC_DELAY1[7:0] set the delay-1 time-interval (tDELAY-1) for the related ESM_MCU or ESM_SoC. Use #GUID-DF6532B4-B17E-4C92-B12D-2D4021966C59/SLVSE82707 and #GUID-DF6532B4-B17E-4C92-B12D-2D4021966C59/SLVSE827308 to calculate the worst-case values for the tDELAY-1: Min. tDELAY-1 = (ESM_x_DELAY1[7:0] × 2.048 ms) × 0.95 Max. tDELAY-1 = (ESM _x_DELAY1[7:0] × 2.048 ms) × 1.05 , in which x stands for either MCU or SoC.

Level Mode In Level Mode, after MCU has set the start bit (bit ESM_MCU_START or bit ESM_SOC_START), the ESM monitors its nERR_MCU or nERR_SoC input pin. Each ESM detects an ESM-error when the voltage level on its input pin remains low for a time equal or longer than the deglitch-time tdegl_ESMx. When an ESM_x detects an ESM-error, it starts the ESM Error-Handling procedure as described in . The Error-Handling Procedure is stopped if, before elapse of the delay-1 or delay-2 interval, the voltage level on the input pin remains high for a time equal or longer than the deglitch-time tdegl_ESMx and the MCU clears all corresponding interrupt bits. If the ESM-error persists such that the configured delay-1 and delay-2 times elapse, the ESM sends a ESM_x_RST trigger to the PFSM and the device clear the ESM_x_START bit. After the PFSM completes the handling of the ESM_x_RST trigger, the device re-initializes the ESM. For a complete overview on how the ESM works in Level Mode, please refer to the flow-chart in .

If the input signal remains low after exceeding the maximum low-pulse time-threshold (tLOW_MAX_TH), the ESM detects a bad event and the low-pulse duration counter reinitializes. Each time the signal further exceeds the maximum threshold, the ESM detects a bad event. On the next rising edge on the input signal, the ESM starts the high-pulse time-duration monitoring After a rising edge, the ESM starts monitoring the high-pulse time-duration. If the input signal remains high after exceeding the maximum high-pulse time-threshold (tHIGH_MAX_TH), the ESM detects a bad event and the high-pulse duration counter reinitializes. Each time the signal further exceeds the maximum threshold, the ESM detects a bad event. On the next falling edge on the input signal, the ESM starts the low-pulse time-duration monitoring. In addition, each ESM detects a bad-event in PWM mode if one of the events that follow occurs on the deglitched signal of the related input pin nERR_MCU or nERR_SoC: A high-pulse time-duration that is longer than the maximum high-pulse time-threshold (tHIGH_MAX_TH) that is configured in corresponding register bits ESM_MCU_HMAX[7:0] or ESM_SOC_HMAX[7:0].

Please note that when setting up the minimum and the maximum low-pulse or high-pulse time-thresholds need to be configured such that clock tolerances from the TPS6593-Q1 and from the processor are incorporated. #GUID-8AB05BFB-234E-4174-9368-666CD9A02C95/SLVSE826982, #GUID-8AB05BFB-234E-4174-9368-666CD9A02C95/SLVSE823780, #GUID-8AB05BFB-234E-4174-9368-666CD9A02C95/SLVSE827462, and #GUID-8AB05BFB-234E-4174-9368-666CD9A02C95/SLVSE825152 are a guideline on how to incorporate these clock-tolerances: ESM_x_HMIN[7:0] < 0.5 × (ESM_x_HMAX[7:0] + ESM_x_HMIN[7:0]) × 0.95 × (1 - MCU/SoC clock tolerance) ESM_x_HMAX[7:0] > 0.5 × (ESM_x_HMAX[7:0] + ESM_x_HMIN[7:0]) × 1.05 × (1 + MCU/SoC clock tolerance) ESM_x_LMIN[7:0] < 0.5 × (ESM_x_LMAX[7:0] + ESM_x_LMIN[7:0]) × 0.95 × (1 - MCU/SoC clock tolerance) ESM_x_LMAX[7:0] > 0.5 × (ESM_x_LMAX[7:0] + ESM_x_LMIN[7:0]) × 1.05 × (1 + MCU/SoC clock tolerance) , in which x stands for either MCU or SoC. ESM Error-Counter If an ESM detects a bad-event, it increments its related error-counter (bits ESM_MCU_ERR_CNT[4:0] or bits ESM_SOC_ERR_CNT[4:0]) by 2. If an ESM detects a good-event, it decrements its related error-counter (bits ESM_MCU_ERR_CNT[4:0] or bits ESM_SOC_ERR_CNT[4:0]) by 1. The device clears each ESM error counter when ESM_x_START=0. Furthermore, the device clears the error-counter ESM_SOC_ERR[4:0] when it resets the SoC. Each ESM error-counter has a related threshold (bits ESM_MCU_ERR_CNT_TH[3:0] or bits ESM_SOC_ERR_CNT_TH[3:0]) that the MCU can configure if the related ESM_x_START bit is 0. If the ESM error-counter value is above its configured threshold, the related ESM has detected a so-called ESM-error and starts the Error-Handling Procedure as described in . If the ESM error-counter reached a value equal or less its configured threshold before the elapse of the configured delay-1 or delay-2 intervals and the MCU software clears all ESM related interrupt bits, the ESM-error is no longer present and the ESM stops the Error-Handling Procedure as described in . If the ESM-error persists such that the configured delay-1 and delay-2 times elapse, the ESM sends a ESM_x_RST trigger to the PFSM and the device clears the ESM_x_START bit. After the PFSM completes the handling of the ESM_x_RST trigger, the device re-initializes the related ESM. ESM Start-Up in PWM Mode After the MCU has set the start bit of an ESM (bit ESM_MCU_START or bit ESM_SOC_START), there are two possible scenarios: The deglitched signal of the monitored input pin has a low level at the moment the MCU sets the start bit. In this scenario, the related ESM starts the following procedure: Start a timer with a time-length according the value configured in corresponding ESM_MCU_LMAX[7:0] or ESM_SOC_LMAX[7:0]. Wait for a first rising edge on its deglitched input signal. If the rising edge comes before the configured time-length elapses, the ESM skips the next step and starts to monitor the high-pulse duration time. Hereafter, the ESM detects good-events or bad-events as described in . shows an example this scenario as Case Number 1. If the configured time-length (configured in corresponding ESM_MCU_LMAX[7:0] or ESM_SOC_LMAX[7:0]) elapses, the ESM detects a bad-event and increments the related error-counter with +2. Hereafter, the ESM detects good-events or bad-events as described in . shows an example this scenario as Case Number 3. If the ESM error-counter value is above its configured threshold, the related ESM has detected a so-called ESM-error and starts the Error-Handling Procedure as described in . During this Error-Handling Procedure, the ESM continues to monitor its related input pin, and updates the error-counter accordingly when it detects good-events or bad-events, until the Error-Handling Procedure reaches the step in which the ESM sends an ESM_x_RST trigger to the PFSM, which, depending on the PFSM configuration, resets the MCU or SoC. shows a scenario in which the device resets the MCU or SoC as Case Number 4. If the ESM error-counter reaches a value equal or less its configured threshold before the elapse of the configured delay-1 or delay-2 time-intervals and the MCU software clears all ESM related interrupt bits, the ESM-error is no longer present and the ESM stops the Error-Handling Procedure as described in . The deglitched signal monitored input pin has a high level at the moment the MCU sets the start bit. In this scenario, the related ESM starts the following procedure: Start a timer with a time-length according the value configured in corresponding ESM_MCU_HMAX[7:0] or ESM_SOC_HMAX[7:0]. Wait for a first falling edge on its deglitched input signal. If the falling edge comes before the configured time-length elapses, the ESM skips the next step and starts to monitor the low-pulse duration time. Hereafter, the ESM detects good-events or bad-events as described in . shows an example this scenario as Case Number 2. If the configured time-length (configured in corresponding ESM_MCU_HMAX[7:0] or ESM_SOC_HMAX[7:0]) elapses, the ESM detects a bad-event and increments the related error-counter with +2. Hereafter, the ESM detects good-events or bad-events as described in . If the ESM error-counter value is above its configured threshold, the related ESM has detected a so-called ESM-error and starts the Error-Handling Procedure as described in . During this Error-Handling Procedure, the ESM continues to monitor its related input pin, and updates the error-counter accordingly when it detects good-events or bad-events, until the Error-Handling Procedure reaches the step in which the ESM sends an ESM_x_RST trigger to the PFSM, which, depending on the PFSM configuration, resets the MCU or SoC, as Case Number 4. If the ESM error-counter reaches a value equal or less its configured threshold before the elapse of the configured delay-1 or delay-2 time-intervals and the MCU software clears all ESM related interrupt bits, the ESM-error is no longer present and the ESM stops the Error-Handling Procedure as described in .

VCCA Monitor VCCA Monitor Power Resources (Bucks and LDOs) The power resources provided by the TPS6593-Q1 device includes synchronous, current mode control bucks and linear LDOs. These supply resources provide power to the external processors, components, and modules inside the TPS6593-Q1 device. The supply of the bucks, the PVIN_Bx pins, must connect to the VCCA pin externally. The supply of the LDOs, the PVIN_LDOx pins, may connect to the VCCA pin or a buck output which is at a lower voltage level than the VCCA. The voltage output of each power resource is continuously monitored by a dedicated analog monitor on an independent reference voltage domain. An unused regulator can also be used as a voltage monitor for an external rail by connecting the external rail to the FB_Bn the VOUT_LDOn pin. #GUID-4B7B2915-7E2F-4669-92C2-3E88664B9019/SLVSE825742 lists the power resources provided by the TPS6593-Q1 device.

All of the buck converters support the following features: Automatic mode control based on the loading (PFM or PWM mode) or Forced-PWM mode operation External clock synchronization option to minimize crosstalk Optional spread spectrum technique to reduce EMI Soft start AVS support with configurable slew-rate Windowed undervoltage and overvoltage monitors with configurable threshold Windowed voltage monitor for external supply when the buck converter is inactive Output Current Limit Short-to-Ground Detection on SW_Bx pins at start-up of the buck regulator When the outputs of these buck converters are combined in multi-phase configuration, it also supports the following features: Current balancing between the phases of the converter Differential voltage sensing from point of the load Phase shifted outputs for EMI reduction Optional dynamic phase shedding or adding There are two modes of operation for the buck converter, depending on the required output current: pulse-width modulation (PWM) and pulse-frequency modulation (PFM). The converter operates in PWM mode at high load currents of approximately 600 mA or higher. Lighter output current loads cause the converter to automatically switch into PFM mode for reduced current consumption. The device avoids pulse skipping and allows easy filtering of the switch noise by external filter components when forced-PWM mode is selected (BUCKn_FPWM = 1). The forced-PWM mode is the recommended mode of operation for the buck converter to achieve better ripple and transient performance. The drawback of this forced-PWM mode is the higher quiescent current at low output current levels. When operating in PWM mode the phases of a multi-phase regulator are automatically added or shed based on the load current level. The forced multi-phase mode can be enabled for lower ripple at the output. shows a block diagram of a single core. shows the interleaving switching action of the multi-phase converters. BUCK Core Block Diagram Example of PWM Timings, Inductor Current Waveforms, and Total Output Current in 4-Phase Configuration. (1) Multi-Phase Operation and Phase-Adding or Shedding The 4-phase converters (BUCK1, BUCK2, BUCK3, and BUCK4) switches each channel 90° apart under heavy load conditions. As a result, the 4-phase converter has an effective ripple frequency four times greater than the switching frequency of any one phase. In the same way, 3-phase converter has an effective ripple frequency three times greater and 2-phase converter has an effective ripple frequency two times greater than the switching frequency of any one phase; the parallel operation, however, decreases the efficiency at light load conditions. The TPS6593-Q1 can change the number of active phases to optimize efficiency for the variations of the load in order to overcome this operational inefficiency. The process in which the multi-phase buck regulator in case of increasing load current automatically increases the number of active phases is called phase adding. The process in which the multi-phase buck regulator in case of decreasing load current automatically decreases the number of active phases is called phase shedding. The concept is shown in . The converter can be forced to multi-phase operation by the BUCKn_FPWM_MP bit in BUCKn_CTRL1 register. If the regulator operates in forced multi-phase mode , each phase automatically operates in the forced-PWM mode. If the multi-phase operation is not forced, the number of phases are added and shed automatically to follow the required output current. Multiphase BUCK Converter Efficiency vs Number of Phases (Converters in PWM Mode) (1) Transition Between PWM and PFM Modes The forced-PWM mode operation with phase-adding or shedding optimizes efficiency at mid-to-full load. TheTPS6593-Q1 converter operates in PWM mode at load current of approximately 600 mA or higher. The device automatically switches into PFM mode for reduced current consumption when forced-PWM mode is not enabled (BUCKn_FPWM = 0) at lighter load-current levels. A high efficiency is achieved over a wide output-load-current range by combining the PFM and the PWM modes. Multi-Phase BUCK Regulator Configurations The control of the multi-phase regulator settings is done using the control registers of the primary BUCK regulator in the multi-phase configuration. The TPS6593-Q1 ignores settings in the following registers of the secondary and, if used, the tertiary and quaternary BUCK regulators : BUCKn_CTRL register, except BUCKn_VMON_EN BUCKn_CONF register BUCKn_VOUT_1 and BUCKn_VOUT_2 registers BUCKn_PG_WINDOW register Interrupt bits related to the secondary and, if sued, the tertiary and quaternary BUCK regulator, except BUCKn_ILIM_INT, BUCKn_ILIM_MASK and BUCKn_ILIM_STAT #GUID-E61220E0-AB07-48B8-BBB5-1EEC54C6C2D1/SLVSE828295 shows the supported Multi-Phase BUCK regulator configurations and the assigned primary BUCK regulator in each configuration. Primary BUCK Assignment for Supported Multi-phase Configuration Supported Multi-Phase BUCK Regulator Configuration Primary BUCK Assignment 4-Phase: BUCK1 + BUCK2 + BUCK3 + BUCK4 BUCK1 3-Phase: BUCK1 + BUCK2 + BUCK3 BUCK1 2-Phase: BUCK1 + BUCK2 BUCK1 2-Phase: BUCK3 + BUCK4 BUCK3 When the BUCK regulators are configured in 3-phase or 4-phase configurations, there are exceptions to the above list of registers that the TPS6593-Q1 ignores. The configuration registers are user-configurable for the voltage monitor function on BUCK3 and BUCK4 in a 4-phase configuration and BUCK3 in a 3-phase configuration. The UV/OV voltage monitors of these BUCK3 and BUCK4 regulators can be used to monitor external supply rails, by connecting these external rails to the FB_Bn pins of these BUCK3 and BUCK4 regulators. The following list of registers and register bits for BUCK3 and BUCK4 can be used to enable and set the target voltage for the external voltage monitoring function under such configuration: BUCKn_VMON_EN bit BUCKn_VSEL bit BUCKn_SLEW_RATE BUCKn_VOUT_1 and BUCKn_VOUT_2 registers BUCKn_PG_WINDOW register Customers are responsible for the values set in these registers when using BUCK3 or BUCK4 to monitor an external supply under the 3-phase or 4-phase configuration. If the voltage monitor function is not used under such a scenario, the FB_Bn pins must be connected to the reference ground, and the BUCKn_VMON_EN bits must be set to '0'. Spread-Spectrum Mode The TPS6593-Q1 device supports spread-spectrum modulation of the switching clock signal used by the BUCK regulators. Three factory-selectable modulation modes are available: the first mode is modulation from external input clock at the SYNCCLKIN pin; the second mode is modulating the input clock at the SYNCCLKIN pin using the DPLL; the third mode is modulating the internal 20-MHz RC-Oscillator clock using the DPLL. The spread-spectrum modulation mode is pre-configured in NVM. Changing this modulation mode during operation is not supported. The modulation frequency range is limited by the DPLL bandwidth. The max frequency spread for the input clock to the DPLL is ±18% to secure parametric compliance of the BUCK output performance. The internal modulation is inactive by default and can be enabled and configured after power up. Internal modulation is activated by setting the SS_EN control bit. The internal modulation must be inactive (SS_EN = 0) when changing the following parameter: SS_DEPTH[1:0] – Spread Spectrum modulation depth When internal modulation is enabled and configured, it can be made inactive by the system MCU during operation. The device transition to different mission states does not impact internal modulation when it is enabled and configured. Adaptive Voltage Scaling (AVS) and Dynamic Voltage Scaling (DVS) Support An AVS or a DVS voltage value can be configured by the attached MCU after the BUCK regulator is powered up to the default output voltage selected in register BUCKn_VSET1, that loads its default value from NVM. The purpose of the AVS/DVS voltage is to set the BUCK output voltage to enable optimal efficiency and performance of the attached SoC. All of BUCK regulators in the TPS6593-Q1 device support AVS and DVS voltage scaling changes. Once the AVS/DVS voltage value is written into the BUCKn_VSET1 or BUCKn_VSET2 register, and the MCU sets the BUCKn_VSEL register to select the AVS/DVS voltage, the output of the BUCK regulator remains at the AVS/DVS voltage level instead of the default voltage from NVM until one of the following events occur: Error that causes the device to re-initialize itself through a power cycle after reaching the SAFE RECOVERY state Error that causes the device to execute warm reset MCU configures the device to enter the LP STANDBY state shows the arbitration scheme for loading the output level of the BUCK regulator from the AVS register using the BUCKn_VSET control registers. AVS/DVS Configuration Register Arbitration Diagram The digital control block automatically updates the OV and UV threshold of the BUCK output voltage monitor during the AVS or DVS voltage change. When the output voltage is increased, the OV threshold is updated at the same time the BUCKn_VSETx is updated to the AVS voltage level, while the UV threshold is updated after a delay calculated by . When the output voltage is decreased, the UV threshold is updated at the same time the BUCKn_VSETx is updated to the AVS voltage level, while the OV threshold is updated after a delay calculated by . tPG_OV_UV_DELAY = (dV / BUCKn_SLEW_RATE) + tsettle_Bx In order to prevent erroneous voltage monitoring, the digital block also temporarily masks the results of the OV and UV monitor from the regulator output when the BUCK regulator is enabled and the voltage is rising to the BUCKn_VSETx level. The duration of the mask starts from the time the BUCK regulator is enabled. The BUCK OV monitor output is masked for a fixed delay time of tPG_OV_GATE, that is approximately 115 µs – 128 µs. The UV monitor output is masked for the time duration calculated by . The 370-µs additional delay time in the formula includes the start-up delay of the BUCK regulator, and the fixed delay after the ramp. tPG_UV_GATE = (BUCKn_VSET / BUCKn_SLEW_RATE) + 370 µs Because output capacitance, forward and negative current limits and load current of the BUCK regulator may affect the slew rate of the BUCK regulator output voltage, the delay time of tPG_UV_GATE may not be sufficient long for the slower slew rate setting when the target BUCK regulator output voltage is higher.

The High-Side Current Limit, also referred to as Forward Current Limit, is for BUCK1..4 adjustable between 2.5 A and 5.5 A with 1-A steps with register bits BUCKx_ILIM[3:0]. For BUCK5, this Forward Current Limit has selectable levels 2.5 A and 3.5 A with register bits BUCK5_ILIM[3:0]. The Low-Side Current Limit, also referred to as Negative Current Limit, has a fixed value of typical 2 A. SW_Bx Short-to-Ground Detection Each BUCK regulator includes a SW_Bx Short-to-Ground Detection. This SW_Bx Short-to-Ground Detection monitors whether the SW_B1...SW_B5 pins have a short-to-ground condition, either caused by external short on these pins or caused by a short in the low-side power-FET of the BUCK regulator. This SW_Bx Short to Ground Detection is activated before the power-up of the BUCK regulator. When this function detects a short-to-ground condition on the SW_B1...SW_B5 pins, the TPS6593-Q1 aborts the power-up sequence and sets the corresponding interrupt bits BUCKx_SC_INT (x=1...5). After this, the TPS6593-Q1 transitions to the SAFE RECOVERY state, after which it performs an attempt to restart as described in . Sync Clock Functionality The TPS6593-Q1 device contains a SYNCCLKIN (GPIO10) input to synchronize switching clock of the BUCK regulator with the external clock. The block diagram of the clocking and PLL module is shown in . The external clock is selected when the external clock is available, and SEL_EXT_CLK = '1'. The nominal frequency of the external input clock is set by EXT_CLK_FREQ[1:0] bits in the NVM and it can be 1.1 MHz, 2.2 MHz, or 4.4 MHz. The external SYNCCLKIN clock must be inside accuracy limits (–18%/+18%) of the typical input frequency for valid clock detection. The EXT_CLK_INT interrupt is generated in case the external clock is expected (SEL_EXT_CLK = 1), but it is not available or the clock frequency is not within the valid range. The TPS6593-Q1 device can also generate a clock signal, SYNCCLKOUT, for external device use. The SYNCCLKOUT_FREQ_SEL[1:0] selects the frequency of the SYNCCLKOUT. Note: SYNCCLKOUT_FREQ_SEL[1:0] must stay static while SYNCCLKOUT is used, as changing the output frequency selection can cause glitches on the clock output. The SYNCCLKOUT is available through GPIO8, GPIO9, or GPIO10. Sync Clock and DPLL Module Low Dropout Regulators (LDOs) All of the LDO regulators in the TPS6593-Q1 device can be supplied by the system supply or another pre-regulated voltage source which are within the specified VIN range. The PVIN_LDOn voltage level must be equal or less than the VCCA voltage level to ensure proper operation of the LDOs. The default output voltages of all LDOs are loaded from the NVM memory and can be configured by the LDOn_VSET[7:0]. There is no hardware protection to prevent software from selecting an improper output voltage if the minimum level of PVIN_LDOn is lower than the dropout voltage of the LDO regulator in addition to the configured LDO output voltage. In such conditions, the output voltage droops to near the PVIN_LDOn level. Writing a RESERVED value to the LDOn_VSET[7:0] register bits causes a LDOn_OV_INT or LDOn_UV_INT interrupt. The LDO regulators do not have slew rate control for voltage ramp; by setting the LDOn_SLOW_RAMP bit to '1', however, the ramp up speed of the regulator output voltage is < 3 V/ms. If an LDO is not needed, its associated UV/OV Voltage Monitor can be used to monitor an external voltage rail by connecting the external rail to the VOUT_LDOn pin. The voltage level of the monitored external rail must be within the PGOOD monitor range of the LDOn_VSET[7:0] of the LDO. If an external resistor divider is necessary in this case, the user must take into account the input impedance at the VOUT_LDOn pin (as shown in ), and adjust the resistor values to compensate for the voltage shift. Impedance at the VOUT_LDOn Pins LDOVINT The LDOVINT voltage regulator is dedicated to supply the digital and analog functions of the TPS6593-Q1 device, which are not required to be always-on and can be turned-off when the device is in low power states. The LDOVINT voltage regulator is automatically turned on and off as needed if LP_STANDBY_SEL = '1'. The automatic control optimizes the overall current consumption when the device is in low power LP_STANDBY state. The LDOVINT voltage regulator is dedicated for internal use only, and cannot be used to support external loads. An output filtering capacitor must be connected at the VOUT_LDOVINT pin. Do not connect any other components or external loads to this VOUT_LDOVINT pin. LDOVRTC The LDOVRTC voltage regulator supplies always-on functions, such as wake-up functions. This power resource is active as soon as a valid VCCA is present. The LDOVRTC voltage regulator is dedicated for internal use only, and cannot be used to support external loads. An output filtering capacitor must be connected at the VOUT_LDOVRTC pin. Do not connect any other components or external loads to this VOUT_LDOVRTC pin. This voltage regulator is enabled in normal mode or backup mode. The LDOVRTC voltage regulator functions in normal mode when supplied from the main system power rail and is able to supply the input buffers of GPIO3 and GPIO4, the digital components, the crystal, and the RTC calendar module of the TPS6593-Q1 device. The LDOVRTC voltage regulator remains on in BACKUP state when VCCA is below the VCCA_UVLO level, and the backup power source is above the LDOVRTC_UVLO level. Only the 32 kHz crystal and the RTC counter are activated in the BACKUP state. The RTC calendar function remains active in the LP_STANDBY state, but the interrupt functions are reduced to maintaining the wake up functions only. The RTC calendar and interrupt functions are fully activated in the mission states. The customer has the option to enable the shelf mode by setting the LDORTC_DIS bit to 1 while the device is in the MISSION state and the I2C bus is in operation and ramp down VCCA to 0 V immediately after the I2C write has completed. This shelf mode forces the device to skip the BACKUP state and enters the NO SUPPLY state under VCCA_UVLO condition. This mode is useful to prevent the continual draining of the backup power source when the 32 KHz crystal and RTC counter functions are no longer needed. LDO1, LDO2, and LDO3 A 20220110 Added LDO1, LDO2, LDO3 Current Limit descriptionyes The LDO1, LDO2 and LDO3 regulators can deliver up to 500 mA of current, with a configurable output range of 0.6 V to 3.3 V in 50-mV steps. These 3 LDO regulators also support bypass mode, which allows an input voltage at the PVIN_LDOn to show up at the VOUT_LDOn pin. This feature allows the LDOs to be configured as load switches with power sequencing control. Similar to the buck regulators mentioned in , the UV/OV Voltage Monitor of an un-used LDO regulator can also be used to monitor an external voltage rail by connecting the external rail to the VOUT_LDOn pin. The bypass capability to connect the input voltage to the output in bypass mode is supported when the input voltage is within the 1.7 V to 3.5 V range. This bypass capability also allows the LDO to switch from 3.3 V in bypass mode to 1.8 V in LDO mode or from 1.8 V in LDO mode to 3.3 V in bypass mode for an SD card I/O supply. The LDO1, LDO2 and LDO3 regulator include a Current-Limit to protect the internal Power-FET against overcurrent. This Current-Limit has a fixed value between 700 mA and 1800 mA. It is important to wait until the LDO has settled on the target voltage from the previous change when changing the LDO output voltage setting. The worst-case voltage scaling time for LDO1, LDO2, and LDO3 is 63 µs x (7 + the number of 50-mV steps to the new target voltage). #GUID-EC409DDC-2E1D-4E58-8C0F-5BA31078220E/X2414 shows the coding used to select the output voltage for LDO1, LDO2, and LDO3.

This LDO is specifically designed to supply noise sensitive circuits. This supply can be used to power circuits such as PLLs, oscillators, or other analog modules that require low noise on the supply. LDO4 does not support bypass mode. However, if the LDO4 output voltage is not used, the associated UV/OV Voltage Monitor of this regulator can be used as to monitor an external voltage rail by connecting this external voltage rail to the VOUT_LDO4 pin. The LDO4 regulator includes a Current-Limit to protect the internal Power-FET against overcurrent.

All of the buck converters support the following features: Automatic mode control based on the loading (PFM or PWM mode) or Forced-PWM mode operation External clock synchronization option to minimize crosstalk Optional spread spectrum technique to reduce EMI Soft start AVS support with configurable slew-rate Windowed undervoltage and overvoltage monitors with configurable threshold Windowed voltage monitor for external supply when the buck converter is inactive Output Current Limit Short-to-Ground Detection on SW_Bx pins at start-up of the buck regulator When the outputs of these buck converters are combined in multi-phase configuration, it also supports the following features: Current balancing between the phases of the converter Differential voltage sensing from point of the load Phase shifted outputs for EMI reduction Optional dynamic phase shedding or adding There are two modes of operation for the buck converter, depending on the required output current: pulse-width modulation (PWM) and pulse-frequency modulation (PFM). The converter operates in PWM mode at high load currents of approximately 600 mA or higher. Lighter output current loads cause the converter to automatically switch into PFM mode for reduced current consumption. The device avoids pulse skipping and allows easy filtering of the switch noise by external filter components when forced-PWM mode is selected (BUCKn_FPWM = 1). The forced-PWM mode is the recommended mode of operation for the buck converter to achieve better ripple and transient performance. The drawback of this forced-PWM mode is the higher quiescent current at low output current levels. When operating in PWM mode the phases of a multi-phase regulator are automatically added or shed based on the load current level. The forced multi-phase mode can be enabled for lower ripple at the output. shows a block diagram of a single core. shows the interleaving switching action of the multi-phase converters. BUCK Core Block Diagram Example of PWM Timings, Inductor Current Waveforms, and Total Output Current in 4-Phase Configuration. (1) Multi-Phase Operation and Phase-Adding or Shedding The 4-phase converters (BUCK1, BUCK2, BUCK3, and BUCK4) switches each channel 90° apart under heavy load conditions. As a result, the 4-phase converter has an effective ripple frequency four times greater than the switching frequency of any one phase. In the same way, 3-phase converter has an effective ripple frequency three times greater and 2-phase converter has an effective ripple frequency two times greater than the switching frequency of any one phase; the parallel operation, however, decreases the efficiency at light load conditions. The TPS6593-Q1 can change the number of active phases to optimize efficiency for the variations of the load in order to overcome this operational inefficiency. The process in which the multi-phase buck regulator in case of increasing load current automatically increases the number of active phases is called phase adding. The process in which the multi-phase buck regulator in case of decreasing load current automatically decreases the number of active phases is called phase shedding. The concept is shown in . The converter can be forced to multi-phase operation by the BUCKn_FPWM_MP bit in BUCKn_CTRL1 register. If the regulator operates in forced multi-phase mode , each phase automatically operates in the forced-PWM mode. If the multi-phase operation is not forced, the number of phases are added and shed automatically to follow the required output current. Multiphase BUCK Converter Efficiency vs Number of Phases (Converters in PWM Mode) (1) Transition Between PWM and PFM Modes The forced-PWM mode operation with phase-adding or shedding optimizes efficiency at mid-to-full load. TheTPS6593-Q1 converter operates in PWM mode at load current of approximately 600 mA or higher. The device automatically switches into PFM mode for reduced current consumption when forced-PWM mode is not enabled (BUCKn_FPWM = 0) at lighter load-current levels. A high efficiency is achieved over a wide output-load-current range by combining the PFM and the PWM modes. Multi-Phase BUCK Regulator Configurations The control of the multi-phase regulator settings is done using the control registers of the primary BUCK regulator in the multi-phase configuration. The TPS6593-Q1 ignores settings in the following registers of the secondary and, if used, the tertiary and quaternary BUCK regulators : BUCKn_CTRL register, except BUCKn_VMON_EN BUCKn_CONF register BUCKn_VOUT_1 and BUCKn_VOUT_2 registers BUCKn_PG_WINDOW register Interrupt bits related to the secondary and, if sued, the tertiary and quaternary BUCK regulator, except BUCKn_ILIM_INT, BUCKn_ILIM_MASK and BUCKn_ILIM_STAT #GUID-E61220E0-AB07-48B8-BBB5-1EEC54C6C2D1/SLVSE828295 shows the supported Multi-Phase BUCK regulator configurations and the assigned primary BUCK regulator in each configuration. Primary BUCK Assignment for Supported Multi-phase Configuration Supported Multi-Phase BUCK Regulator Configuration Primary BUCK Assignment 4-Phase: BUCK1 + BUCK2 + BUCK3 + BUCK4 BUCK1 3-Phase: BUCK1 + BUCK2 + BUCK3 BUCK1 2-Phase: BUCK1 + BUCK2 BUCK1 2-Phase: BUCK3 + BUCK4 BUCK3 When the BUCK regulators are configured in 3-phase or 4-phase configurations, there are exceptions to the above list of registers that the TPS6593-Q1 ignores. The configuration registers are user-configurable for the voltage monitor function on BUCK3 and BUCK4 in a 4-phase configuration and BUCK3 in a 3-phase configuration. The UV/OV voltage monitors of these BUCK3 and BUCK4 regulators can be used to monitor external supply rails, by connecting these external rails to the FB_Bn pins of these BUCK3 and BUCK4 regulators. The following list of registers and register bits for BUCK3 and BUCK4 can be used to enable and set the target voltage for the external voltage monitoring function under such configuration: BUCKn_VMON_EN bit BUCKn_VSEL bit BUCKn_SLEW_RATE BUCKn_VOUT_1 and BUCKn_VOUT_2 registers BUCKn_PG_WINDOW register Customers are responsible for the values set in these registers when using BUCK3 or BUCK4 to monitor an external supply under the 3-phase or 4-phase configuration. If the voltage monitor function is not used under such a scenario, the FB_Bn pins must be connected to the reference ground, and the BUCKn_VMON_EN bits must be set to '0'. Spread-Spectrum Mode The TPS6593-Q1 device supports spread-spectrum modulation of the switching clock signal used by the BUCK regulators. Three factory-selectable modulation modes are available: the first mode is modulation from external input clock at the SYNCCLKIN pin; the second mode is modulating the input clock at the SYNCCLKIN pin using the DPLL; the third mode is modulating the internal 20-MHz RC-Oscillator clock using the DPLL. The spread-spectrum modulation mode is pre-configured in NVM. Changing this modulation mode during operation is not supported. The modulation frequency range is limited by the DPLL bandwidth. The max frequency spread for the input clock to the DPLL is ±18% to secure parametric compliance of the BUCK output performance. The internal modulation is inactive by default and can be enabled and configured after power up. Internal modulation is activated by setting the SS_EN control bit. The internal modulation must be inactive (SS_EN = 0) when changing the following parameter: SS_DEPTH[1:0] – Spread Spectrum modulation depth When internal modulation is enabled and configured, it can be made inactive by the system MCU during operation. The device transition to different mission states does not impact internal modulation when it is enabled and configured. Adaptive Voltage Scaling (AVS) and Dynamic Voltage Scaling (DVS) Support An AVS or a DVS voltage value can be configured by the attached MCU after the BUCK regulator is powered up to the default output voltage selected in register BUCKn_VSET1, that loads its default value from NVM. The purpose of the AVS/DVS voltage is to set the BUCK output voltage to enable optimal efficiency and performance of the attached SoC. All of BUCK regulators in the TPS6593-Q1 device support AVS and DVS voltage scaling changes. Once the AVS/DVS voltage value is written into the BUCKn_VSET1 or BUCKn_VSET2 register, and the MCU sets the BUCKn_VSEL register to select the AVS/DVS voltage, the output of the BUCK regulator remains at the AVS/DVS voltage level instead of the default voltage from NVM until one of the following events occur: Error that causes the device to re-initialize itself through a power cycle after reaching the SAFE RECOVERY state Error that causes the device to execute warm reset MCU configures the device to enter the LP STANDBY state shows the arbitration scheme for loading the output level of the BUCK regulator from the AVS register using the BUCKn_VSET control registers. AVS/DVS Configuration Register Arbitration Diagram The digital control block automatically updates the OV and UV threshold of the BUCK output voltage monitor during the AVS or DVS voltage change. When the output voltage is increased, the OV threshold is updated at the same time the BUCKn_VSETx is updated to the AVS voltage level, while the UV threshold is updated after a delay calculated by . When the output voltage is decreased, the UV threshold is updated at the same time the BUCKn_VSETx is updated to the AVS voltage level, while the OV threshold is updated after a delay calculated by . tPG_OV_UV_DELAY = (dV / BUCKn_SLEW_RATE) + tsettle_Bx In order to prevent erroneous voltage monitoring, the digital block also temporarily masks the results of the OV and UV monitor from the regulator output when the BUCK regulator is enabled and the voltage is rising to the BUCKn_VSETx level. The duration of the mask starts from the time the BUCK regulator is enabled. The BUCK OV monitor output is masked for a fixed delay time of tPG_OV_GATE, that is approximately 115 µs – 128 µs. The UV monitor output is masked for the time duration calculated by . The 370-µs additional delay time in the formula includes the start-up delay of the BUCK regulator, and the fixed delay after the ramp. tPG_UV_GATE = (BUCKn_VSET / BUCKn_SLEW_RATE) + 370 µs Because output capacitance, forward and negative current limits and load current of the BUCK regulator may affect the slew rate of the BUCK regulator output voltage, the delay time of tPG_UV_GATE may not be sufficient long for the slower slew rate setting when the target BUCK regulator output voltage is higher. Please refer to the PMIC user's guide for detail information about the supported voltage level and slew rate setting combinations of a particular orderable part number. and are timing diagrams illustrating the voltage change for AVS and DVS enabled BUCK regulators and the corresponding OV and UV monitor threshold changes.

The High-Side Current Limit, also referred to as Forward Current Limit, is for BUCK1..4 adjustable between 2.5 A and 5.5 A with 1-A steps with register bits BUCKx_ILIM[3:0]. For BUCK5, this Forward Current Limit has selectable levels 2.5 A and 3.5 A with register bits BUCK5_ILIM[3:0]. The Low-Side Current Limit, also referred to as Negative Current Limit, has a fixed value of typical 2 A. SW_Bx Short-to-Ground Detection Each BUCK regulator includes a SW_Bx Short-to-Ground Detection. This SW_Bx Short-to-Ground Detection monitors whether the SW_B1...SW_B5 pins have a short-to-ground condition, either caused by external short on these pins or caused by a short in the low-side power-FET of the BUCK regulator. This SW_Bx Short to Ground Detection is activated before the power-up of the BUCK regulator. When this function detects a short-to-ground condition on the SW_B1...SW_B5 pins, the TPS6593-Q1 aborts the power-up sequence and sets the corresponding interrupt bits BUCKx_SC_INT (x=1...5). After this, the TPS6593-Q1 transitions to the SAFE RECOVERY state, after which it performs an attempt to restart as described in . Sync Clock Functionality The TPS6593-Q1 device contains a SYNCCLKIN (GPIO10) input to synchronize switching clock of the BUCK regulator with the external clock. The block diagram of the clocking and PLL module is shown in . The external clock is selected when the external clock is available, and SEL_EXT_CLK = '1'. The nominal frequency of the external input clock is set by EXT_CLK_FREQ[1:0] bits in the NVM and it can be 1.1 MHz, 2.2 MHz, or 4.4 MHz. The external SYNCCLKIN clock must be inside accuracy limits (–18%/+18%) of the typical input frequency for valid clock detection. The EXT_CLK_INT interrupt is generated in case the external clock is expected (SEL_EXT_CLK = 1), but it is not available or the clock frequency is not within the valid range. The TPS6593-Q1 device can also generate a clock signal, SYNCCLKOUT, for external device use. The SYNCCLKOUT_FREQ_SEL[1:0] selects the frequency of the SYNCCLKOUT. Note: SYNCCLKOUT_FREQ_SEL[1:0] must stay static while SYNCCLKOUT is used, as changing the output frequency selection can cause glitches on the clock output. The SYNCCLKOUT is available through GPIO8, GPIO9, or GPIO10. Sync Clock and DPLL Module Buck Regulators BUCK Regulator Overview A 20220110 BUCK Regulator Overview: added Current Limityes The TPS6593-Q1 includes five synchronous buck converters, of which four can be combined in multi-phase configuration. All of the buck converters support the following features: Automatic mode control based on the loading (PFM or PWM mode) or Forced-PWM mode operation External clock synchronization option to minimize crosstalk Optional spread spectrum technique to reduce EMI Soft start AVS support with configurable slew-rate Windowed undervoltage and overvoltage monitors with configurable threshold Windowed voltage monitor for external supply when the buck converter is inactive Output Current Limit Short-to-Ground Detection on SW_Bx pins at start-up of the buck regulator When the outputs of these buck converters are combined in multi-phase configuration, it also supports the following features: Current balancing between the phases of the converter Differential voltage sensing from point of the load Phase shifted outputs for EMI reduction Optional dynamic phase shedding or adding There are two modes of operation for the buck converter, depending on the required output current: pulse-width modulation (PWM) and pulse-frequency modulation (PFM). The converter operates in PWM mode at high load currents of approximately 600 mA or higher. Lighter output current loads cause the converter to automatically switch into PFM mode for reduced current consumption. The device avoids pulse skipping and allows easy filtering of the switch noise by external filter components when forced-PWM mode is selected (BUCKn_FPWM = 1). The forced-PWM mode is the recommended mode of operation for the buck converter to achieve better ripple and transient performance. The drawback of this forced-PWM mode is the higher quiescent current at low output current levels. When operating in PWM mode the phases of a multi-phase regulator are automatically added or shed based on the load current level. The forced multi-phase mode can be enabled for lower ripple at the output. shows a block diagram of a single core. shows the interleaving switching action of the multi-phase converters.

Multi-Phase Operation and Phase-Adding or Shedding The 4-phase converters (BUCK1, BUCK2, BUCK3, and BUCK4) switches each channel 90° apart under heavy load conditions. As a result, the 4-phase converter has an effective ripple frequency four times greater than the switching frequency of any one phase. In the same way, 3-phase converter has an effective ripple frequency three times greater and 2-phase converter has an effective ripple frequency two times greater than the switching frequency of any one phase; the parallel operation, however, decreases the efficiency at light load conditions. The TPS6593-Q1 can change the number of active phases to optimize efficiency for the variations of the load in order to overcome this operational inefficiency. The process in which the multi-phase buck regulator in case of increasing load current automatically increases the number of active phases is called phase adding. The process in which the multi-phase buck regulator in case of decreasing load current automatically decreases the number of active phases is called phase shedding. The concept is shown in . The converter can be forced to multi-phase operation by the BUCKn_FPWM_MP bit in BUCKn_CTRL1 register.

Spread-Spectrum Mode The TPS6593-Q1 device supports spread-spectrum modulation of the switching clock signal used by the BUCK regulators. Three factory-selectable modulation modes are available: the first mode is modulation from external input clock at the SYNCCLKIN pin; the second mode is modulating the input clock at the SYNCCLKIN pin using the DPLL; the third mode is modulating the internal 20-MHz RC-Oscillator clock using the DPLL. The spread-spectrum modulation mode is pre-configured in NVM. Changing this modulation mode during operation is not supported. The modulation frequency range is limited by the DPLL bandwidth. The max frequency spread for the input clock to the DPLL is ±18% to secure parametric compliance of the BUCK output performance. The internal modulation is inactive by default and can be enabled and configured after power up. Internal modulation is activated by setting the SS_EN control bit. The internal modulation must be inactive (SS_EN = 0) when changing the following parameter: SS_DEPTH[1:0] – Spread Spectrum modulation depth When internal modulation is enabled and configured, it can be made inactive by the system MCU during operation.

The internal modulation must be inactive (SS_EN = 0) when changing the following parameter: SS_DEPTH[1:0] – Spread Spectrum modulation depth When internal modulation is enabled and configured, it can be made inactive by the system MCU during operation. The device transition to different mission states does not impact internal modulation when it is enabled and configured. The TPS6593-Q1 device supports spread-spectrum modulation of the switching clock signal used by the BUCK regulators. Three factory-selectable modulation modes are available: the first mode is modulation from external input clock at the SYNCCLKIN pin; the second mode is modulating the input clock at the SYNCCLKIN pin using the DPLL; the third mode is modulating the internal 20-MHz RC-Oscillator clock using the DPLL.TPS6593-Q1The spread-spectrum modulation mode is pre-configured in NVM. Changing this modulation mode during operation is not supported.The modulation frequency range is limited by the DPLL bandwidth.

Adaptive Voltage Scaling (AVS) and Dynamic Voltage Scaling (DVS) Support An AVS or a DVS voltage value can be configured by the attached MCU after the BUCK regulator is powered up to the default output voltage selected in register BUCKn_VSET1, that loads its default value from NVM. The purpose of the AVS/DVS voltage is to set the BUCK output voltage to enable optimal efficiency and performance of the attached SoC. All of BUCK regulators in the TPS6593-Q1 device support AVS and DVS voltage scaling changes. Once the AVS/DVS voltage value is written into the BUCKn_VSET1 or BUCKn_VSET2 register, and the MCU sets the BUCKn_VSEL register to select the AVS/DVS voltage, the output of the BUCK regulator remains at the AVS/DVS voltage level instead of the default voltage from NVM until one of the following events occur: Error that causes the device to re-initialize itself through a power cycle after reaching the SAFE RECOVERY state Error that causes the device to execute warm reset MCU configures the device to enter the LP STANDBY state shows the arbitration scheme for loading the output level of the BUCK regulator from the AVS register using the BUCKn_VSET control registers.

SW_Bx Short-to-Ground Detection Each BUCK regulator includes a SW_Bx Short-to-Ground Detection. This SW_Bx Short-to-Ground Detection monitors whether the SW_B1...SW_B5 pins have a short-to-ground condition, either caused by external short on these pins or caused by a short in the low-side power-FET of the BUCK regulator. This SW_Bx Short to Ground Detection is activated before the power-up of the BUCK regulator. When this function detects a short-to-ground condition on the SW_B1...SW_B5 pins, the TPS6593-Q1 aborts the power-up sequence and sets the corresponding interrupt bits BUCKx_SC_INT (x=1...5).

The block diagram of the clocking and PLL module is shown in . The external clock is selected when the external clock is available, and SEL_EXT_CLK = '1'. The nominal frequency of the external input clock is set by EXT_CLK_FREQ[1:0] bits in the NVM and it can be 1.1 MHz, 2.2 MHz, or 4.4 MHz. The external SYNCCLKIN clock must be inside accuracy limits (–18%/+18%) of the typical input frequency for valid clock detection. The EXT_CLK_INT interrupt is generated in case the external clock is expected (SEL_EXT_CLK = 1), but it is not available or the clock frequency is not within the valid range. The TPS6593-Q1 device can also generate a clock signal, SYNCCLKOUT, for external device use. The SYNCCLKOUT_FREQ_SEL[1:0] selects the frequency of the SYNCCLKOUT. Note: SYNCCLKOUT_FREQ_SEL[1:0] must stay static while SYNCCLKOUT is used, as changing the output frequency selection can cause glitches on the clock output. The SYNCCLKOUT is available through GPIO8, GPIO9, or GPIO10.

The PVIN_LDOn voltage level must be equal or less than the VCCA voltage level to ensure proper operation of the LDOs. The default output voltages of all LDOs are loaded from the NVM memory and can be configured by the LDOn_VSET[7:0]. There is no hardware protection to prevent software from selecting an improper output voltage if the minimum level of PVIN_LDOn is lower than the dropout voltage of the LDO regulator in addition to the configured LDO output voltage. In such conditions, the output voltage droops to near the PVIN_LDOn level. Writing a RESERVED value to the LDOn_VSET[7:0] register bits causes a LDOn_OV_INT or LDOn_UV_INT interrupt. The LDO regulators do not have slew rate control for voltage ramp; by setting the LDOn_SLOW_RAMP bit to '1', however, the ramp up speed of the regulator output voltage is < 3 V/ms. If an LDO is not needed, its associated UV/OV Voltage Monitor can be used to monitor an external voltage rail by connecting the external rail to the VOUT_LDOn pin. The voltage level of the monitored external rail must be within the PGOOD monitor range of the LDOn_VSET[7:0] of the LDO. If an external resistor divider is necessary in this case, the user must take into account the input impedance at the VOUT_LDOn pin (as shown in ), and adjust the resistor values to compensate for the voltage shift. Impedance at the VOUT_LDOn Pins LDOVINT The LDOVINT voltage regulator is dedicated to supply the digital and analog functions of the TPS6593-Q1 device, which are not required to be always-on and can be turned-off when the device is in low power states. The LDOVINT voltage regulator is automatically turned on and off as needed if LP_STANDBY_SEL = '1'. The automatic control optimizes the overall current consumption when the device is in low power LP_STANDBY state. The LDOVINT voltage regulator is dedicated for internal use only, and cannot be used to support external loads. An output filtering capacitor must be connected at the VOUT_LDOVINT pin. Do not connect any other components or external loads to this VOUT_LDOVINT pin. LDOVRTC The LDOVRTC voltage regulator supplies always-on functions, such as wake-up functions. This power resource is active as soon as a valid VCCA is present. The LDOVRTC voltage regulator is dedicated for internal use only, and cannot be used to support external loads. An output filtering capacitor must be connected at the VOUT_LDOVRTC pin. Do not connect any other components or external loads to this VOUT_LDOVRTC pin. This voltage regulator is enabled in normal mode or backup mode. The LDOVRTC voltage regulator functions in normal mode when supplied from the main system power rail and is able to supply the input buffers of GPIO3 and GPIO4, the digital components, the crystal, and the RTC calendar module of the TPS6593-Q1 device. The LDOVRTC voltage regulator remains on in BACKUP state when VCCA is below the VCCA_UVLO level, and the backup power source is above the LDOVRTC_UVLO level. Only the 32 kHz crystal and the RTC counter are activated in the BACKUP state. The RTC calendar function remains active in the LP_STANDBY state, but the interrupt functions are reduced to maintaining the wake up functions only. The RTC calendar and interrupt functions are fully activated in the mission states. The customer has the option to enable the shelf mode by setting the LDORTC_DIS bit to 1 while the device is in the MISSION state and the I2C bus is in operation and ramp down VCCA to 0 V immediately after the I2C write has completed. This shelf mode forces the device to skip the BACKUP state and enters the NO SUPPLY state under VCCA_UVLO condition. This mode is useful to prevent the continual draining of the backup power source when the 32 KHz crystal and RTC counter functions are no longer needed.

These 3 LDO regulators also support bypass mode, which allows an input voltage at the PVIN_LDOn to show up at the VOUT_LDOn pin. This feature allows the LDOs to be configured as load switches with power sequencing control. Similar to the buck regulators mentioned in , the UV/OV Voltage Monitor of an un-used LDO regulator can also be used to monitor an external voltage rail by connecting the external rail to the VOUT_LDOn pin. The bypass capability to connect the input voltage to the output in bypass mode is supported when the input voltage is within the 1.7 V to 3.5 V range. This bypass capability also allows the LDO to switch from 3.3 V in bypass mode to 1.8 V in LDO mode or from 1.8 V in LDO mode to 3.3 V in bypass mode for an SD card I/O supply. The LDO1, LDO2 and LDO3 regulator include a Current-Limit to protect the internal Power-FET against overcurrent. This Current-Limit has a fixed value between 700 mA and 1800 mA. It is important to wait until the LDO has settled on the target voltage from the previous change when changing the LDO output voltage setting. The worst-case voltage scaling time for LDO1, LDO2, and LDO3 is 63 µs x (7 + the number of 50-mV steps to the new target voltage). #GUID-EC409DDC-2E1D-4E58-8C0F-5BA31078220E/X2414 shows the coding used to select the output voltage for LDO1, LDO2, and LDO3.

explanation on how to use Voltage Monitors of unused BUCK and LDO regulatorsyes The TPS6593-Q1 device monitors the undervoltage (UV) and overvoltage (OV) conditions on the output voltages of the BUCK and LDO, regulators and VCCA (when it is expected to be 5 V or 3.3 V), and has the option to indicate the result with a PGOOD signal. Thermal warning can also be included in the result of the PGOOD monitor if it is not masked. Either voltage and current monitoring or only voltage monitoring can be selected for PGOOD indication. This selection is set by the PGOOD_SEL_BUCKn register bits for each BUCK regulator (select primary phase for multi-phase regulator), and is set by the PGOOD_SEL_LDOn register bits for each LDO regulator. When voltage and current are monitored, an active PGOOD signal active indicates that the regulator output is inside the Power-Good voltage window and that load current is below the current limit. If only voltage is monitored, then the current monitoring is ignored for the PGOOD signal. The PGOOD signal represents the momentary status of the included indications without latching. If the PGOOD signal goes low due to an indicated warning or error condition, the PGOOD signal goes high immediately when the previous indicated warning or error condition is no longer present. The BUCKn_VMON_EN bit enables the overvoltage (OV) , undervoltage (UV) and short-circuit (SC) comparators. The current limit (ILIM) comparator of each BUCK regulator is activated as soon as the corresponding BUCK regulator is enabled. In order to add the current limit indication of a BUCK regulator to the PGOOD signal, the BUCKn_VMON_EN bit of the corresponding BUCK regulator must be set. For LDO regulators, the LDOn_VMON_EN bit enables the OV and UV, short-circuit (SC) comparators. The current limit (ILIM) comparator of each LDO regulator is activated as soon as the corresponding LDO regulator is enabled. In order to add the current limit indication of an LDO to the PGOOD signal, the LDOn_VMON_EN bit of the corresponding LDO regulator must be set. When a BUCK or an LDO is not needed as a regulated output, it can be used as a voltage monitor for an external rail. For BUCK converters, if the BUCKn_VMON_EN bit remains '1' while the BUCKn_EN bit is '0', it can be used as a voltage monitor for an external rail that is connected to the FB_Bn pin of the BUCK regulator. For LDO regulators, if the LDOn_VMON_EN bit remains '1' while the LDOn_EN bit is '0', it can be used as a voltage monitor for an external rail which is connected to the VOUT_LDOn pin. When the voltage monitor for a BUCK or LDO regulator is inactive, the output of the corresponding monitor is automatically masked to prevent it from forcing PGOOD inactive. The masking allows PGOOD to be connected to other open-drain power good signals in the system. The VCCA input voltage monitoring is enabled with VCCA_VMON_EN bit. The monitoring can be enabled by an NVM default setting, that starts the monitoring of the VCCA voltage after the device passes the BOOT BIST state. The reference voltage for the VCCA monitor can be set by the VCCA_PG_SET bit to either 3.3 V or 5 V. The PGOOD_SEL_VCCA register bit selects whether or not the result of the VCCA monitor is included in the PGOOD monitor output signal. An NVM option is available to gate the PGOOD output with the nRSTOUT and the nRSTOUT_SoC signals, the intended reset signals for the safety MCU and the SoC respectively. When PGOOD_SEL_NRSTOUT = '1', the PGOOD pin is gated by the nRSTOUT signal. When PGOOD_SEL_NRSTOUT_SOC = '1', the PGOOD pin is gated by the nRSTOUT_SoC signal. This option allows the PGOOD output to be used as an enable signal for external peripherals. The outputs of the voltage monitors from all the output rails are combined, and PGOOD is active only if all the sources shows active status. The type of output voltage monitoring for PGOOD signal is selected by PGOOD_WINDOW bit. If the bit is 0, only undervoltage is monitored; if the bit is 1, then undervoltage and overvoltage are monitored. The polarity and the output type (push-pull or open-drain) are selected by PGOOD_POL and GPIO9_OD bits. shows the Power-Good generation block diagram, and shows the Power-Good waveforms. PGOOD Block Diagram PGOOD Waveforms The OV and UV threshold of the voltage monitors of the BUCK regulators and the LDO regulators are updated automatically by the digital control block when the output voltage setting changes. When the output voltage of the regulator is increased, the OV threshold is updated at the same time the _VSET of the regulator is changed. The UV threshold is updated after a delay calculated by the delta voltage change and the slew rate setting. When the output voltage is decreased, the UV threshold is updated at the same time the _VSET of the regulator is changed. The OV threshold is updated after a delay calculated by the delta voltage change and the slew rate setting. The OV and UV threshold of the BUCK and LDO output voltage monitors are calculated based on the target output voltage set by the corresponding BUCKn_VSET1, BUCKn_VSET2, or LDOn_VSET registers, and the deviation from the target output voltage set (the voltage window) by the corresponding BUCKn_UV_THR, BUCKn_OV_THR, LDOn_UV_THR, and the LDOn_OV_THR registers. For the OV and UV threshold of BUCK and LDO output monitors to update with the correct timing, the following operating procedures must be followed when updating the _VSET values of the regulators to avoid detection of OV/UV fault: BUCK and LDO regulators must be enabled at the same time as or earlier than as their VMON New voltage level must not be set before the start-up has finished New voltage level must not be set before the previous voltage change (ramp plus settling time) has completed The voltage monitors of unused BUCK or LDO regulators can be used for external supply rails monitoring. In three-phase configuration, the Voltage Monitor of BUCK3 (on FB_B3 pin) becomes a free available resource for monitoring an external supply voltage. In four-phase configuration, the Voltage Monitor of both BUCK3 (on FB_B3 pin) and BUCK4 (on FB_B4 pin) become free available resources for monitoring two external supply voltages.. The target output voltage is set by the corresponding BUCKn_VSET1, BUCKn_VSET2, or LDOn_VSET registers, and the deviation from the target output voltage set (the voltage window) by the corresponding BUCKn_UV_THR, BUCKn_OV_THR, LDOn_UV_THR, and the LDOn_OV_THR registers. Following aspects need to be taken into account if Voltage Monitors of unused BUCK or LDO regulators are used for monitoring external supply rails: For voltage monitors of unused LDO regulators: the voltage level applied at the VOUT_LDOx pin, inclusive expected tolerances, must be below the supply voltage applied at the PVIN_LDOx pin For voltage monitors of unused BUCK and LDO regulators: the maximum nominal supply voltage of the monitored supply rail is 3.3V For voltage monitors of unused BUCK regulators and for voltage monitors of BUCK3 and/or BUCK4 regulators if used in a three-phase or four-phase configuration: the configured values for the BUCKn_VSET and the BUCKn_SLEW_RATE determine the delay-time for the voltage monitoring to become active after the corresponding BUCKn_VMON_EN bit is set. See equation (2) in . If BUCK3 and/or BUCK4 regulators are used in a three-phase or four-phase configuration: even though the values for the BUCK1_VSET and BUCK1_SLEW_RATE bits determine the output voltage and slew-rate of the three-phase or four-phase output rail, the values for BUCK3_VSET respectively BUCK4_VSET and BUCK3_SLEW_RATE respectively BUCK4_SLEW_RATE bits determine the power-good level and the voltage monitoring delay time for the BUCK3 respectively BUCK4 Voltage Monitors. For voltage monitors of unused LDO regulators: the delay-time for the voltage monitoring to become active after the corresponding LDOn_VMON_EN bit is set it 601..606μs.

When the output voltage of the regulator is increased, the OV threshold is updated at the same time the _VSET of the regulator is changed. The UV threshold is updated after a delay calculated by the delta voltage change and the slew rate setting. When the output voltage is decreased, the UV threshold is updated at the same time the _VSET of the regulator is changed. The OV threshold is updated after a delay calculated by the delta voltage change and the slew rate setting. The OV and UV threshold of the BUCK and LDO output voltage monitors are calculated based on the target output voltage set by the corresponding BUCKn_VSET1, BUCKn_VSET2, or LDOn_VSET registers, and the deviation from the target output voltage set (the voltage window) by the corresponding BUCKn_UV_THR, BUCKn_OV_THR, LDOn_UV_THR, and the LDOn_OV_THR registers. For the OV and UV threshold of BUCK and LDO output monitors to update with the correct timing, the following operating procedures must be followed when updating the _VSET values of the regulators to avoid detection of OV/UV fault: BUCK and LDO regulators must be enabled at the same time as or earlier than as their VMON New voltage level must not be set before the start-up has finished New voltage level must not be set before the previous voltage change (ramp plus settling time) has completed The voltage monitors of unused BUCK or LDO regulators can be used for external supply rails monitoring. In three-phase configuration, the Voltage Monitor of BUCK3 (on FB_B3 pin) becomes a free available resource for monitoring an external supply voltage. In four-phase configuration, the Voltage Monitor of both BUCK3 (on FB_B3 pin) and BUCK4 (on FB_B4 pin) become free available resources for monitoring two external supply voltages.. The target output voltage is set by the corresponding BUCKn_VSET1, BUCKn_VSET2, or LDOn_VSET registers, and the deviation from the target output voltage set (the voltage window) by the corresponding BUCKn_UV_THR, BUCKn_OV_THR, LDOn_UV_THR, and the LDOn_OV_THR registers. Following aspects need to be taken into account if Voltage Monitors of unused BUCK or LDO regulators are used for monitoring external supply rails: For voltage monitors of unused LDO regulators: the voltage level applied at the VOUT_LDOx pin, inclusive expected tolerances, must be below the supply voltage applied at the PVIN_LDOx pin For voltage monitors of unused BUCK and LDO regulators: the maximum nominal supply voltage of the monitored supply rail is 3.3V For voltage monitors of unused BUCK regulators and for voltage monitors of BUCK3 and/or BUCK4 regulators if used in a three-phase or four-phase configuration: the configured values for the BUCKn_VSET and the BUCKn_SLEW_RATE determine the delay-time for the voltage monitoring to become active after the corresponding BUCKn_VMON_EN bit is set. See equation (2) in . If BUCK3 and/or BUCK4 regulators are used in a three-phase or four-phase configuration: even though the values for the BUCK1_VSET and BUCK1_SLEW_RATE bits determine the output voltage and slew-rate of the three-phase or four-phase output rail, the values for BUCK3_VSET respectively BUCK4_VSET and BUCK3_SLEW_RATE respectively BUCK4_SLEW_RATE bits determine the power-good level and the voltage monitoring delay time for the BUCK3 respectively BUCK4 Voltage Monitors. For voltage monitors of unused LDO regulators: the delay-time for the voltage monitoring to become active after the corresponding LDOn_VMON_EN bit is set it 601..606μs. The TPS6593-Q1 device monitors the undervoltage (UV) and overvoltage (OV) conditions on the output voltages of the BUCK and LDO, regulators and VCCA (when it is expected to be 5 V or 3.3 V), and has the option to indicate the result with a PGOOD signal. Thermal warning can also be included in the result of the PGOOD monitor if it is not masked. Either voltage and current monitoring or only voltage monitoring can be selected for PGOOD indication. This selection is set by the PGOOD_SEL_BUCKn register bits for each BUCK regulator (select primary phase for multi-phase regulator), and is set by the PGOOD_SEL_LDOn register bits for each LDO regulator. When voltage and current are monitored, an active PGOOD signal active indicates that the regulator output is inside the Power-Good voltage window and that load current is below the current limit. If only voltage is monitored, then the current monitoring is ignored for the PGOOD signal. The PGOOD signal represents the momentary status of the included indications without latching. If the PGOOD signal goes low due to an indicated warning or error condition, the PGOOD signal goes high immediately when the previous indicated warning or error condition is no longer present. The BUCKn_VMON_EN bit enables the overvoltage (OV) , undervoltage (UV) and short-circuit (SC) comparators. The current limit (ILIM) comparator of each BUCK regulator is activated as soon as the corresponding BUCK regulator is enabled. In order to add the current limit indication of a BUCK regulator to the PGOOD signal, the BUCKn_VMON_EN bit of the corresponding BUCK regulator must be set. For LDO regulators, the LDOn_VMON_EN bit enables the OV and UV, short-circuit (SC) comparators. The current limit (ILIM) comparator of each LDO regulator is activated as soon as the corresponding LDO regulator is enabled. In order to add the current limit indication of an LDO to the PGOOD signal, the LDOn_VMON_EN bit of the corresponding LDO regulator must be set. When a BUCK or an LDO is not needed as a regulated output, it can be used as a voltage monitor for an external rail. For BUCK converters, if the BUCKn_VMON_EN bit remains '1' while the BUCKn_EN bit is '0', it can be used as a voltage monitor for an external rail that is connected to the FB_Bn pin of the BUCK regulator. For LDO regulators, if the LDOn_VMON_EN bit remains '1' while the LDOn_EN bit is '0', it can be used as a voltage monitor for an external rail which is connected to the VOUT_LDOn pin. When the voltage monitor for a BUCK or LDO regulator is inactive, the output of the corresponding monitor is automatically masked to prevent it from forcing PGOOD inactive. The masking allows PGOOD to be connected to other open-drain power good signals in the system. The VCCA input voltage monitoring is enabled with VCCA_VMON_EN bit. The monitoring can be enabled by an NVM default setting, that starts the monitoring of the VCCA voltage after the device passes the BOOT BIST state. The reference voltage for the VCCA monitor can be set by the VCCA_PG_SET bit to either 3.3 V or 5 V. The PGOOD_SEL_VCCA register bit selects whether or not the result of the VCCA monitor is included in the PGOOD monitor output signal. An NVM option is available to gate the PGOOD output with the nRSTOUT and the nRSTOUT_SoC signals, the intended reset signals for the safety MCU and the SoC respectively. When PGOOD_SEL_NRSTOUT = '1', the PGOOD pin is gated by the nRSTOUT signal. When PGOOD_SEL_NRSTOUT_SOC = '1', the PGOOD pin is gated by the nRSTOUT_SoC signal. This option allows the PGOOD output to be used as an enable signal for external peripherals. The outputs of the voltage monitors from all the output rails are combined, and PGOOD is active only if all the sources shows active status. The type of output voltage monitoring for PGOOD signal is selected by PGOOD_WINDOW bit. If the bit is 0, only undervoltage is monitored; if the bit is 1, then undervoltage and overvoltage are monitored. The polarity and the output type (push-pull or open-drain) are selected by PGOOD_POL and GPIO9_OD bits. shows the Power-Good generation block diagram, and shows the Power-Good waveforms.

Thermal Monitoring The TPS6593-Q1 device includes several thermal monitoring functions for internal thermal protection of the PMIC. The TPS6593-Q1 device integrates thermal detection modules to monitor the temperature of the die. These modules are placed on opposite sides of the device and close to the LDO and BUCK modules. An over-temperature condition at either module first generates a warning to the system, and if the temperature continues to rise, then a switch-off of the PMIC device can occur before damage to the die. Three thermal protection levels are available. One of these protections is a thermal warning function described in , that sends an interrupt to software. Software is expected to close any noncritical running tasks to reduce power. The second and third protections are the thermal shutdown (TS) function described in , that begins device shutdown orderly or immediately. Thermal monitoring is automatically enabled when one of the BUCK or LDO outputs is enabled within the mission states. The thermal monitoring is deactivated in the LP_STANDBY state, when only the internal regulators are enabled, to minimize the device power consumption. Indication of a thermal warning event is written to the TWARN_INT register. The current consumption of the thermal monitoring can be decreased in the mission states when the low power dissipation is important. If LPM_EN bit is set and the temperature is below thermal warning level in all thermal detection modules, only one thermal detection module is monitored. If the temperature rises in this module, monitoring in all thermal detection modules is started. If the die temperature of the TPS6593-Q1 device continues to rise while the device is in mission state, an TSD_ORD_INT or TSD_IMM_INT interrupt is generated, causing a SEVERE or MODERATE error trigger (respectively) in the state machine. While the sequencing and error handling is NVM memory dependent, TI recommends a sequenced shutdown for MODERATE errors, and an immediate shutdown, using resistive discharging, for SEVERE errors to prevent damage to the device. The system cannot restart until the temperature falls below the thermal warning threshold. Thermal Warning Function The thermal monitor provides a warning to the host processor through the interrupt system when the temperature reaches within a cautionary range. The threshold value must be set to less than the thermal shutdown threshold. The integrated thermal warning function provides the MCU an early warning of over-temperature condition. This monitoring system is connected to the interrupt controller and can send an TWARN_INT interrupt when the temperature is higher than the preset threshold. The TPS6593-Q1 device uses the TWARN_LEVEL register bit to set the thermal warning threshold temperature at 130°C or 140°C. There is no hysteresis for the thermal warning level. When the power-management software triggers an interrupt, immediate action must be taken to reduce the amount of power drawn from the PMIC device (for example, noncritical applications must be closed). Thermal Shutdown The thermal shutdown detector monitors the temperature on the die. If the junction reaches a temperature at which damage can occur, a switch-off transition is initiated and a thermal shutdown event is written into a status register. There are two levels of thermal shutdown threshold. When the die temperature reaches the TSD_orderly level, the TPS6593-Q1 device performs an orderly shutdown of all output power rails. If the die temperature raises rapidly and reaches the TSD_imm level before the orderly shutdown process completes, the TPS6593-Q1 device performs an immediate shutdown with activated pull-down on all output power rails, in order to turn off all of the output power rails as rapidly as possible. After the thermal shutdown takes place, the system cannot restart until the die temperature is below the thermal warning threshold.

These modules are placed on opposite sides of the device and close to the LDO and BUCK modules. An over-temperature condition at either module first generates a warning to the system, and if the temperature continues to rise, then a switch-off of the PMIC device can occur before damage to the die.TPS6593-Q1LDO andThree thermal protection levels are available. One of these protections is a thermal warning function described in , that sends an interrupt to software. Software is expected to close any noncritical running tasks to reduce power. The second and third protections are the thermal shutdown (TS) function described in , that begins device shutdown orderly or immediately.Thermal monitoring is automatically enabled when one of the BUCK or LDO outputs is enabled within the mission states. The thermal monitoring is deactivated in the LP_STANDBY state, when only the internal regulators are enabled, to minimize the device power consumption. Indication of a thermal warning event is written to the TWARN_INT register.or LDO LP_STANDBY regulators areThe current consumption of the thermal monitoring can be decreased in the mission states when the low power dissipation is important. If LPM_EN bit is set and the temperature is below thermal warning level in all thermal detection modules, only one thermal detection module is monitored. If the temperature rises in this module, monitoring in all thermal detection modules is started.If the die temperature of the TPS6593-Q1 device continues to rise while the device is in mission state, an TSD_ORD_INT or TSD_IMM_INT interrupt is generated, causing a SEVERE or MODERATE error trigger (respectively) in the state machine. While the sequencing and error handling is NVM memory dependent, TI recommends a sequenced shutdown for MODERATE errors, and an immediate shutdown, using resistive discharging, for SEVERE errors to prevent damage to the device. The system cannot restart until the temperature falls below the thermal warning threshold.TPS6593-Q1 Thermal Warning Function The thermal monitor provides a warning to the host processor through the interrupt system when the temperature reaches within a cautionary range. The threshold value must be set to less than the thermal shutdown threshold. The integrated thermal warning function provides the MCU an early warning of over-temperature condition. This monitoring system is connected to the interrupt controller and can send an TWARN_INT interrupt when the temperature is higher than the preset threshold. The TPS6593-Q1 device uses the TWARN_LEVEL register bit to set the thermal warning threshold temperature at 130°C or 140°C. There is no hysteresis for the thermal warning level. When the power-management software triggers an interrupt, immediate action must be taken to reduce the amount of power drawn from the PMIC device (for example, noncritical applications must be closed).

Thermal Shutdown The thermal shutdown detector monitors the temperature on the die. If the junction reaches a temperature at which damage can occur, a switch-off transition is initiated and a thermal shutdown event is written into a status register. There are two levels of thermal shutdown threshold. When the die temperature reaches the TSD_orderly level, the TPS6593-Q1 device performs an orderly shutdown of all output power rails. If the die temperature raises rapidly and reaches the TSD_imm level before the orderly shutdown process completes, the TPS6593-Q1 device performs an immediate shutdown with activated pull-down on all output power rails, in order to turn off all of the output power rails as rapidly as possible. After the thermal shutdown takes place, the system cannot restart until the die temperature is below the thermal warning threshold.

The power-path is designed to prioritize VCCA to maximize the life of the backup supply. When VCCA drops below the VCCA_UVLO threshold, the device shuts down all rails except the LDOVRTC, and enters the BACKUP mode. At this point, the Backup Supply Power-Path switches to the VBACKUP as the input of LDOVRTC. When the voltage of VCCA returns to level above the VCCA_UVLO threshold level, the power-path switches the input of LDOVRTC back to VCCA. When both the VCCA voltage drop below the VCCA_UVLO threshold, and the VBACKUP voltage drops below 1.7V (RTC_LDO_UVLO threshold), the LDOVRTC is turned OFF and the digital core is reset, which forces the device into the NO SUPPLY state. Note: a backup supply is not required for the device to operate. The device skips the BACKUP state if the VBACKUP pin is grounded.

General-Purpose I/Os (GPIO Pins) The TPS6593-Q1 device integrates eleven configurable general-purpose I/Os that are multiplexed with alternative features as listed in For GPIOs characteristics, refer to Electrical Characteristics tables for Digital Input Signal Parameters and Digital Output Signal Parameters. When configured as primary functions, all GPIOs are controlled through the following set of registers bits under the individual GPIOn_CONF register. GPIOn_DEGLITCH_EN: Enables the 8 µs deglitch time for each GPIO pin (input) GPIOn_PU_PD_EN: Enables the internal pull up or pull down resistor connected to each GPIO pin GPIOn_PU_SEL: Selects the pull up or the pull down resistor to be connected when GPIOn_PU_PD_EN = '1'. '1' = pull-up resistor selected, '0' = pull-down resistor selected GPIOn_OD: Configures the GPIO pin (output) as: '1' = open drain, '0' = push-pull GPIOn_DIR: Configures the input or output direction of each GPIO pin Each GPIO event can generate an interrupt on a rising edge, falling edge, or both, configured through the GPIOn_FALL_MASK and the GPIOn_RISE_MASK register bits. A GPIO-interrupt applies when the primary function (general-purpose I/O) has been selected and also for the following alternative functions: nRSTOUT_SOC PGOOD nERR_MCU nERR_SoC TRIG_WDOG DISABLE_WDOG NSLEEP1, NSLEEP2 WKUP1, WKUP2 LP_WKUP1, LP_WKUP2 The GPIOn_SEL[2:0] register bits under the GPIOn_CONF registers control the selection between a primary and an alternative function. When a pre-defined function is selected, some predetermined IO characteristics (such as pullup, pulldown, push-pull or open drain) for the pin are enforced regardless of the settings of the associated GPIO configuration register. Please note that if the GPIOn_SEL[2:0] is changed during device operation, a signal glitch may occur which may cause digital malfunction, especially if it involves a clock signal such as SCL_I2C2, CLK32KOUT, SCL_SPMI, SYNCCLKIN, or SYNCCLKOUT. Please refer to for more detail on the predetermined IO characteristics for each pre-defined digital interface function. All GPIOs can be configured as a wake-up input when it is configured as a WKUP1 or a WKUP2 signal. Only GPIO3 and GPIO4 can be configured as LP_WKUP1 or LP_WKUP2 signal so that they can be used to wake-up the device from LP_STANDBY state. All GPIOs can also be configured as a NSLEEP1 or a NSLEEP2 input. For more information regarding the usage of the NSLEEPx pins and the WKUPx pins, please refer to and . Any of the GPIO pin can also be configured as part of the power-up sequence to enable external devices such as external BUCKs when it is configured as a general-purpose output port. The nINT pin, the EN_DRV pin, the nRSTOUT pin and the GPIO pin assigned as nRSTOUT_SOC have readback monitoring to detect errors on the signals. The monitoring of the EN_DRV pin checks for mismatch in both low and high levels. For the nINT pin, the nRSTOUT pin and the GPIO pin assigned as nRSTOUT_SOC, the readback monitoring only checks for mismatches in the low level, therefore it is allowed to combine these signals with other external pull-down sources. The readback mismatch is continuously monitored without deglitch circuitry during operation, and the monitoring is gated for tgate_readback period when the signal state is changed or when a new function is selected for the GPIO pin with the GPIOn_SEL bits. NINT_READBACK_INT, EN_DRV_READBACK_INT, NRSTOUT_READBACK_INT, and NRSTOUT_SOC_READBACK_INT are the interrupt bits that are set in an event of a readback mismatch for these pins, respectively.All GPIO pin are set to generic input pins with resistive pull-down before NVM memory is loaded during device power up. Therefore, if any GPIOs has external pull-up resistors connecting to a voltage domain that is energized before the NVM memory is loaded, the GPIO pin is pulled high before the configuration for the pin is loaded from the NVM. For GPIO pins with internal pull down enabled, additional leakage current flows into the GPIO pin if this pin is pulled-up to a voltage higher than the voltage level of its output power domain. If the internal pull down must be enabled, please use a resistor divider to divide down the input voltage, or use a series resistor to connect to the input source and ensure the voltage level at the GPIO pin is below the voltage level of its output power domain.

The interrupts are grouped into the following categories: BUCK ERROR These interrupts indicate over-voltage (OV), under-voltage (UV), short-circuit (SC) and over-current (ILIM) error conditions found on the BUCK regulators . LDO ERROR These interrupts indicate OV, UV, and SC error conditions found on the LDO regulators, as well as OV and UV error conditions found on the VCCA supply. VMON ERROR These interrupts indicate OV and UV error conditions found on the VCCA supply. SEVERE ERROR These errors indicate severe device error conditions, such as thermal shutdown, PFSM sequencing and execution error and VCCA over-voltage, that causes the device to trigger the PFSM to execute immediate shutdown of all digital outputs, external voltage rails and monitors, and proceed to the Safe Recovery State. MODERATE ERROR These interrupts provide warnings to the system to indicate multiple restart attempts from SAFE RECOVERY state exceeding the allowed recovery count, multiple warm-reset executions exceeding the allowed recovery count, detection of long press nPWRON button, SPMI communication error, register CRC error, BIST failure, read-back error on nRSTOUT or nINT pins, or junction temperature reaching orderly shutdown level. These warning causes the device to trigger the PFSM to execute orderly shutdown of all digital outputs, external voltage rails and monitors, and proceed to the SAFE RECOVERY state.The SEVERE ERROR and the MODERATE ERROR are handled in NVM memory but TI requires that the NVM pre-configurable finite state machine (PFSM) settings always follow this described error handling to meet device specifications. MISCELLANEOUS WARNING These interrupts provide information to the system to indicate detection of WDOG or ESM errors, die temperature crossing thermal warning threshold, device passing BIST test, or external sync clock availability. START-UP SOURCE These interrupts provide information to the system on the mechanism that caused the device to start up, which includes FSD, RTC alarm or timer interrupts, the activation of the ENABLE pin or the nPRWON pin button detection. GPIO DETECTION These interrupts indicate a High-Level or Rising-Edge detection, or indicate a Low-Level or Falling-Edge detection at the GPIO1 through GPIO11 pins. FSM ERROR INTERRUPT These interrupts indicate the detection of an error that causes the device mission state changes. All interrupts are logically combined on a single output pin, nINT (active low). The host processor can read the INT_TOP register to find the interrupt registers to find out the source of the interrupt, and write '1' to the corresponding interrupt register bit to clear the interrupt. This mechanism ensures when a new interrupt occurs while the nINT pin is still active, all of the corresponding interrupt register bits retain the interrupt source information until it is cleared by the host. Hierarchical Structure of Interrupt Registers shows the hierarchical structure of the interrupt registers according to the categories described above. The purpose of this register structure is to reduce the number of interrupt register read cycles the host has to perform in order to identify the source of the interrupt. Summary of Interrupt Signals summarizes the trigger and the clearing mechanism for all of the interrupt signals. This table also shows which interrupt sources can be masked by setting the corresponding mask register to '1'. When an interrupt is masked, the interrupt bit is not updated when the associated event occurs, the nINT line is not affected, and the event is not recorded. If an interrupt is masked after the event occurred, the interrupt register bit reflects the event until the bit is cleared. While the event is masked, the interrupt register bit is not over-written when a new event occurs.

The actual results can be configured differently in NVM memory. TI recommends reviewing of the system and device functional safety goal and documentation before deviating from these recommendations. Interrupt is generated during clock detector operation and in case clock is not available when clock detector is enabled. This event does not occur if RECOV_CNT_THR = 0, even though RECOV_CNT continues to accumulate and increase, and eventually saturates when it reaches the maximum count of 15. Due to a digital logic errata in the device, a write or read SPI command which coincide with the rising edge of the CS signal may not cause the COMM_FRM_ERR_INT interrupt. I2C1, I2C2, or SPI address error only occur in safety applications if the interface CRC feature is enabled, when both I2C1_SPI_CRC_EN and I2C2_CRC_EN are set to '1'. Interrupts The interrupt registers in the device are organized in hierarchical fashion. The interrupts are grouped into the following categories: BUCK ERROR These interrupts indicate over-voltage (OV), under-voltage (UV), short-circuit (SC) and over-current (ILIM) error conditions found on the BUCK regulators . LDO ERROR These interrupts indicate OV, UV, and SC error conditions found on the LDO regulators, as well as OV and UV error conditions found on the VCCA supply. VMON ERROR These interrupts indicate OV and UV error conditions found on the VCCA supply. SEVERE ERROR These errors indicate severe device error conditions, such as thermal shutdown, PFSM sequencing and execution error and VCCA over-voltage, that causes the device to trigger the PFSM to execute immediate shutdown of all digital outputs, external voltage rails and monitors, and proceed to the Safe Recovery State. MODERATE ERROR These interrupts provide warnings to the system to indicate multiple restart attempts from SAFE RECOVERY state exceeding the allowed recovery count, multiple warm-reset executions exceeding the allowed recovery count, detection of long press nPWRON button, SPMI communication error, register CRC error, BIST failure, read-back error on nRSTOUT or nINT pins, or junction temperature reaching orderly shutdown level. These warning causes the device to trigger the PFSM to execute orderly shutdown of all digital outputs, external voltage rails and monitors, and proceed to the SAFE RECOVERY state.The SEVERE ERROR and the MODERATE ERROR are handled in NVM memory but TI requires that the NVM pre-configurable finite state machine (PFSM) settings always follow this described error handling to meet device specifications. MISCELLANEOUS WARNING These interrupts provide information to the system to indicate detection of WDOG or ESM errors, die temperature crossing thermal warning threshold, device passing BIST test, or external sync clock availability. START-UP SOURCE These interrupts provide information to the system on the mechanism that caused the device to start up, which includes FSD, RTC alarm or timer interrupts, the activation of the ENABLE pin or the nPRWON pin button detection. GPIO DETECTION These interrupts indicate a High-Level or Rising-Edge detection, or indicate a Low-Level or Falling-Edge detection at the GPIO1 through GPIO11 pins. FSM ERROR INTERRUPT These interrupts indicate the detection of an error that causes the device mission state changes. All interrupts are logically combined on a single output pin, nINT (active low). The host processor can read the INT_TOP register to find the interrupt registers to find out the source of the interrupt, and write '1' to the corresponding interrupt register bit to clear the interrupt. This mechanism ensures when a new interrupt occurs while the nINT pin is still active, all of the corresponding interrupt register bits retain the interrupt source information until it is cleared by the host. Hierarchical Structure of Interrupt Registers shows the hierarchical structure of the interrupt registers according to the categories described above. The purpose of this register structure is to reduce the number of interrupt register read cycles the host has to perform in order to identify the source of the interrupt. Summary of Interrupt Signals summarizes the trigger and the clearing mechanism for all of the interrupt signals. This table also shows which interrupt sources can be masked by setting the corresponding mask register to '1'. When an interrupt is masked, the interrupt bit is not updated when the associated event occurs, the nINT line is not affected, and the event is not recorded. If an interrupt is masked after the event occurred, the interrupt register bit reflects the event until the bit is cleared. While the event is masked, the interrupt register bit is not over-written when a new event occurs.

The actual results can be configured differently in NVM memory. TI recommends reviewing of the system and device functional safety goal and documentation before deviating from these recommendations. Interrupt is generated during clock detector operation and in case clock is not available when clock detector is enabled. This event does not occur if RECOV_CNT_THR = 0, even though RECOV_CNT continues to accumulate and increase, and eventually saturates when it reaches the maximum count of 15. Due to a digital logic errata in the device, a write or read SPI command which coincide with the rising edge of the CS signal may not cause the COMM_FRM_ERR_INT interrupt. I2C1, I2C2, or SPI address error only occur in safety applications if the interface CRC feature is enabled, when both I2C1_SPI_CRC_EN and I2C2_CRC_EN are set to '1'. The interrupt registers in the device are organized in hierarchical fashion. The interrupts are grouped into the following categories: BUCK ERROR These interrupts indicate over-voltage (OV), under-voltage (UV), short-circuit (SC) and over-current (ILIM) error conditions found on the BUCK regulators . LDO ERROR These interrupts indicate OV, UV, and SC error conditions found on the LDO regulators, as well as OV and UV error conditions found on the VCCA supply. VMON ERROR These interrupts indicate OV and UV error conditions found on the VCCA supply. SEVERE ERROR These errors indicate severe device error conditions, such as thermal shutdown, PFSM sequencing and execution error and VCCA over-voltage, that causes the device to trigger the PFSM to execute immediate shutdown of all digital outputs, external voltage rails and monitors, and proceed to the Safe Recovery State. MODERATE ERROR These interrupts provide warnings to the system to indicate multiple restart attempts from SAFE RECOVERY state exceeding the allowed recovery count, multiple warm-reset executions exceeding the allowed recovery count, detection of long press nPWRON button, SPMI communication error, register CRC error, BIST failure, read-back error on nRSTOUT or nINT pins, or junction temperature reaching orderly shutdown level. These warning causes the device to trigger the PFSM to execute orderly shutdown of all digital outputs, external voltage rails and monitors, and proceed to the SAFE RECOVERY state.The SEVERE ERROR and the MODERATE ERROR are handled in NVM memory but TI requires that the NVM pre-configurable finite state machine (PFSM) settings always follow this described error handling to meet device specifications. MISCELLANEOUS WARNING These interrupts provide information to the system to indicate detection of WDOG or ESM errors, die temperature crossing thermal warning threshold, device passing BIST test, or external sync clock availability. START-UP SOURCE These interrupts provide information to the system on the mechanism that caused the device to start up, which includes FSD, RTC alarm or timer interrupts, the activation of the ENABLE pin or the nPRWON pin button detection. GPIO DETECTION These interrupts indicate a High-Level or Rising-Edge detection, or indicate a Low-Level or Falling-Edge detection at the GPIO1 through GPIO11 pins. FSM ERROR INTERRUPT These interrupts indicate the detection of an error that causes the device mission state changes. All interrupts are logically combined on a single output pin, nINT (active low). The host processor can read the INT_TOP register to find the interrupt registers to find out the source of the interrupt, and write '1' to the corresponding interrupt register bit to clear the interrupt. This mechanism ensures when a new interrupt occurs while the nINT pin is still active, all of the corresponding interrupt register bits retain the interrupt source information until it is cleared by the host. Hierarchical Structure of Interrupt Registers shows the hierarchical structure of the interrupt registers according to the categories described above. The purpose of this register structure is to reduce the number of interrupt register read cycles the host has to perform in order to identify the source of the interrupt. Summary of Interrupt Signals summarizes the trigger and the clearing mechanism for all of the interrupt signals. This table also shows which interrupt sources can be masked by setting the corresponding mask register to '1'. When an interrupt is masked, the interrupt bit is not updated when the associated event occurs, the nINT line is not affected, and the event is not recorded. If an interrupt is masked after the event occurred, the interrupt register bit reflects the event until the bit is cleared. While the event is masked, the interrupt register bit is not over-written when a new event occurs.

The actual results can be configured differently in NVM memory. TI recommends reviewing of the system and device functional safety goal and documentation before deviating from these recommendations. Interrupt is generated during clock detector operation and in case clock is not available when clock detector is enabled. This event does not occur if RECOV_CNT_THR = 0, even though RECOV_CNT continues to accumulate and increase, and eventually saturates when it reaches the maximum count of 15. Due to a digital logic errata in the device, a write or read SPI command which coincide with the rising edge of the CS signal may not cause the COMM_FRM_ERR_INT interrupt. I2C1, I2C2, or SPI address error only occur in safety applications if the interface CRC feature is enabled, when both I2C1_SPI_CRC_EN and I2C2_CRC_EN are set to '1'. The interrupt registers in the device are organized in hierarchical fashion. The interrupts are grouped into the following categories: BUCK ERROR These interrupts indicate over-voltage (OV), under-voltage (UV), short-circuit (SC) and over-current (ILIM) error conditions found on the BUCK regulators . LDO ERROR These interrupts indicate OV, UV, and SC error conditions found on the LDO regulators, as well as OV and UV error conditions found on the VCCA supply. VMON ERROR These interrupts indicate OV and UV error conditions found on the VCCA supply. SEVERE ERROR These errors indicate severe device error conditions, such as thermal shutdown, PFSM sequencing and execution error and VCCA over-voltage, that causes the device to trigger the PFSM to execute immediate shutdown of all digital outputs, external voltage rails and monitors, and proceed to the Safe Recovery State. MODERATE ERROR These interrupts provide warnings to the system to indicate multiple restart attempts from SAFE RECOVERY state exceeding the allowed recovery count, multiple warm-reset executions exceeding the allowed recovery count, detection of long press nPWRON button, SPMI communication error, register CRC error, BIST failure, read-back error on nRSTOUT or nINT pins, or junction temperature reaching orderly shutdown level. These warning causes the device to trigger the PFSM to execute orderly shutdown of all digital outputs, external voltage rails and monitors, and proceed to the SAFE RECOVERY state.The SEVERE ERROR and the MODERATE ERROR are handled in NVM memory but TI requires that the NVM pre-configurable finite state machine (PFSM) settings always follow this described error handling to meet device specifications. MISCELLANEOUS WARNING These interrupts provide information to the system to indicate detection of WDOG or ESM errors, die temperature crossing thermal warning threshold, device passing BIST test, or external sync clock availability.

FSM ERROR INTERRUPTThese interrupts indicate the detection of an error that causes the device mission state changes.All interrupts are logically combined on a single output pin, nINT (active low). The host processor can read the INT_TOP register to find the interrupt registers to find out the source of the interrupt, and write '1' to the corresponding interrupt register bit to clear the interrupt. This mechanism ensures when a new interrupt occurs while the nINT pin is still active, all of the corresponding interrupt register bits retain the interrupt source information until it is cleared by the host.Hierarchical Structure of Interrupt Registers shows the hierarchical structure of the interrupt registers according to the categories described above. The purpose of this register structure is to reduce the number of interrupt register read cycles the host has to perform in order to identify the source of the interrupt. Summary of Interrupt Signals summarizes the trigger and the clearing mechanism for all of the interrupt signals. This table also shows which interrupt sources can be masked by setting the corresponding mask register to '1'. When an interrupt is masked, the interrupt bit is not updated when the associated event occurs, the nINT line is not affected, and the event is not recorded. If an interrupt is masked after the event occurred, the interrupt register bit reflects the event until the bit is cleared. While the event is masked, the interrupt register bit is not over-written when a new event occurs.

RTC General Description The RTC is driven by the 32-kHz oscillator and it provides the alarm and time-keeping functions. The main functions of the RTC block are: Time information (seconds, minutes, and hours) in binary-coded decimal (BCD) code Calendar information (day, month, year, and day of the week) in BCD code up to year 2099 Configurable interrupts generation; the RTC can generate two types interrupts which can be enabled and masked individually: Timer interrupts periodically (1-second, 1-minute, 1-hour, or 1-day periods) Alarm interrupt at a precise time of the day (alarm function) Oscillator frequency calibration and time correction with 1/32768 resolution shows the RTC block diagram. RTC Block Diagram Time Calendar Registers All the time and calendar information is available in the time calendar (TC) dedicated registers: SECONDS_REG, MINUTES_REG, HOURS_REG, DAYS_REG, WEEKS_REG, MONTHS_REG, and YEARS_REG. The TC register values are written in BCD code. Year data ranges from 00 to 99. Leap Year = Year divisible by four (2000, 2004, 2008, 2012, and so on) Common Year = Other years Month data ranges from 01 to 12. Day value ranges: 1 to 31 when months are 1, 3, 5, 7, 8, 10, 12 1 to 30 when months are 4, 6, 9, 11 1 to 29 when month is 2 and year is a leap year 1 to 28 when month is 2 and year is a common year Weekday value ranges from 0 to 6. Hour value ranges from 0 to 23 in 24-hour mode and ranges from 1 to 12 in AM or PM mode. Minutes value ranges from 0 to 59. Seconds value ranges from 0 to 59. Example: Time is 10H54M36S PM (PM_AM mode set), 2008 September 5; previous registers values are listed in #GUID-D55684DC-1A31-4EAF-B994-D540AFAEA45A/SWCS0959413: RTC Time Calendar Registers Example REGISTER CONTENT RTC_SECONDS 0x36 RTC_MINTURES 0x54 RTC_HOURS 0x10 RTC_DAYS 0x05 RTC_MONTHS 0x09 RTC_YEARS 0x08 RTC_WEEKS 0x06 The user can round to the closest minute, by setting the ROUND_30S register bit in the RTC_CTRL_REG register. TC values are set to the closest minute value at the next second. The ROUND_30S bit is automatically cleared when the rounding time is performed. Example: If current time is 10H59M45S, round operation changes time to 11H00M00S If current time is 10H59M29S, round operation changes time to 10H59M00S TC Registers Read Access TC register read access can be done in two ways: A direct read to the TC registers. In this case, there can be a discrepancy between the final time read and the real time because the RTC keeps running because some of the registers can toggle in between register accesses. Software must manage the register change during the reading. Read access to shadowed TC registers. These registers are at the same addresses as the normal TC registers. They are selected by setting the GET_TIME bit in the RTC_CTRL_REG register. When this bit is set, the content of all TC registers is transferred into shadow registers so they represent a coherent timestamp, avoiding any possible discrepancy between them. When processing the read accesses to the TC registers, the value of the shadowed TC registers is returned so it is completely transparent in terms of register access. TC Registers Write Access TC registers write accesses can be done while RTC is stopped. MCU can stop the RTC by the clearing the STOP_RTC bit of the control register and checking the RUN bit of the status to be sure that RTC is frozen. MCU then updates the TC values and restarts the RTC by setting the STOP_RTC bit, which ensures that the final written values are aligned with the targeted values. RTC Alarm RTC alarm registers (ALARM_SECONDS_REG, ALARM_MINUTES_REG, ALARM_HOURS_REG, ALARM_DAYS_REG, ALARM_MONTHS_REG, and ALARM_YEARS_REG) are used to set the alarm time or date to the corresponding generated ALARM interrupts. See for how these register values are written in BCD code, with the same data range as described for the TC registers. RTC Interrupts The RTC supports two types of interrupts: ALARM interrupt. This interrupt is generated when the configured date or time in the corresponding ALARM registers is reached. This interrupt is activated and deactivated by setting the IT_ALARM bit. It is important to set the IT_ALARM = 0 to deactivate the alarm interrupt prior to configuring the ALARM registers to prevent the interrupt from mis-firing. TIMER interrupt. This interrupt is generated when the periodic time (day, hour, minute, second) set in the EVERY bits of the RTC_INTERRUPTS register is reached. The first of the periodic interrupt occurs when the RTC counter reaches the next day, hour, minute, or second counter value. For example, if a timer interrupt is set for every hour at 2:59 AM, the first interrupt occurs at 3:00 AM instead of 3:59 AM. This interrupt is activated and deactivated by setting the IT_TIMER bit. It is important to set the IT_TIMER = 0 to disable the timer interrupt prior to configuring the periodic time value to prevent the interrupt from mis-firing. Both types of the RTC interrupts can be used to wake-up the device from the STANDBY state or the LP_STANDBY state when they are not masked. RTC 32-kHz Oscillator Drift Compensation The RTC_COMP_MSB_REG and RTC_COMP_LSB_REG registers are used to compensate for any inaccuracy of the 32-kHz clock output from the 32-kHz crystal oscillator. To compensate for any inaccuracy, MCU must perform an external calibration of the oscillator frequency by calculating the needed drift compensation compared to one hour time-period, and load the compensation registers with the drift compensation value. The compensation mechanism is enabled by the AUTO_COMP_EN bit in the RTC_CTRL_REG register. The compensation process happens after the first second of each hour. The time between second 1 and second 2 (T_ADJ) is adjusted based on the settings of the two RTC_COMP_MSB_REG and RTC_COMP_LSB_REG registers. These two registers form a 16-bit, 2 s complement value COMP_REG (from –32767 to 32767) that is subtracted from the 32-kHz counter as per the following formula to adjust the length of T_ADJ: (32768 - COMP_REG) / 32768. Therefore, this compensation mechanism can adjust the compensation with a 1/32768-second time-unit accuracy per hour and up to 1 second per hour. Software must ensure that these registers are updated before each compensation process (there is no hardware protection). For example, software can load the compensation value into these registers after each hour event, during second 0 to second 1, just before the compensation period, happening from second 1 to second 2. If the SET_32_COUNTER bit in the RTC_CTRL_REG register is set to '1', the internal 32-kHz counter is pre-loaded with the content of the RTC_COMP_MSB_REG and RTC_COMP_LSB_REG registers. This preloading of the internal 32-kHz counter can only be done when the RTC is stopped. shows the RTC compensation scheduling.

When this bit is set, the content of all TC registers is transferred into shadow registers so they represent a coherent timestamp, avoiding any possible discrepancy between them. When processing the read accesses to the TC registers, the value of the shadowed TC registers is returned so it is completely transparent in terms of register access. TC register read access can be done in two ways: A direct read to the TC registers. In this case, there can be a discrepancy between the final time read and the real time because the RTC keeps running because some of the registers can toggle in between register accesses.

TC Registers Write Access TC registers write accesses can be done while RTC is stopped. MCU can stop the RTC by the clearing the STOP_RTC bit of the control register and checking the RUN bit of the status to be sure that RTC is frozen. MCU then updates the TC values and restarts the RTC by setting the STOP_RTC bit, which ensures that the final written values are aligned with the targeted values.

This interrupt is generated when the configured date or time in the corresponding ALARM registers is reached. This interrupt is activated and deactivated by setting the IT_ALARM bit. It is important to set the IT_ALARM = 0 to deactivate the alarm interrupt prior to configuring the ALARM registers to prevent the interrupt from mis-firing. TIMER interrupt. This interrupt is generated when the periodic time (day, hour, minute, second) set in the EVERY bits of the RTC_INTERRUPTS register is reached. The first of the periodic interrupt occurs when the RTC counter reaches the next day, hour, minute, or second counter value. For example, if a timer interrupt is set for every hour at 2:59 AM, the first interrupt occurs at 3:00 AM instead of 3:59 AM. This interrupt is activated and deactivated by setting the IT_TIMER bit. It is important to set the IT_TIMER = 0 to disable the timer interrupt prior to configuring the periodic time value to prevent the interrupt from mis-firing.

RTC 32-kHz Oscillator Drift Compensation The RTC_COMP_MSB_REG and RTC_COMP_LSB_REG registers are used to compensate for any inaccuracy of the 32-kHz clock output from the 32-kHz crystal oscillator. To compensate for any inaccuracy, MCU must perform an external calibration of the oscillator frequency by calculating the needed drift compensation compared to one hour time-period, and load the compensation registers with the drift compensation value. The compensation mechanism is enabled by the AUTO_COMP_EN bit in the RTC_CTRL_REG register. The compensation process happens after the first second of each hour. The time between second 1 and second 2 (T_ADJ) is adjusted based on the settings of the two RTC_COMP_MSB_REG and RTC_COMP_LSB_REG registers. These two registers form a 16-bit, 2 s complement value COMP_REG (from –32767 to 32767) that is subtracted from the 32-kHz counter as per the following formula to adjust the length of T_ADJ: (32768 - COMP_REG) / 32768. Therefore, this compensation mechanism can adjust the compensation with a 1/32768-second time-unit accuracy per hour and up to 1 second per hour. Software must ensure that these registers are updated before each compensation process (there is no hardware protection). For example, software can load the compensation value into these registers after each hour event, during second 0 to second 1, just before the compensation period, happening from second 1 to second 2. If the SET_32_COUNTER bit in the RTC_CTRL_REG register is set to '1', the internal 32-kHz counter is pre-loaded with the content of the RTC_COMP_MSB_REG and RTC_COMP_LSB_REG registers. This preloading of the internal 32-kHz counter can only be done when the RTC is stopped. shows the RTC compensation scheduling.

RTC Compensation Scheduling RTC Compensation Scheduling Watchdog (WDOG) A 20220110 Watchdog (WDOG): added Q&A (question an answer) modeyes The watchdog monitors the correct operation of the MCU. This watchdog requires specific messages from the MCU in specific time intervals to detect correct operation of the MCU. The MCU can control the logic-level of the EN_DRV pin when the watchdog detects correct operation of the MCU. When the watchdog detects an incorrect operation of the MCU, the TPS6593-Q1 device pulls the EN_DRV pin low . This EN_DRV pin can be used in the application as a control-signal to deactivate the power output stages, for example a motor driver, in case of incorrect operation of the MCU. The watchdog has two different modes that are defined as follows: Trigger mode In trigger mode, the MCU applies a pulse signal with a minimum pulse width of tWD_pulse on the pre-assigned GPIO input pin to send the required watchdog trigger. To select this mode, the MCU must clear bit WD_MODE_SELECT. Watchdog Trigger Mode provides more details. Q&A (question and answer) mode In Q&A mode, the MCU sends watchdog answers through the I2C1 bus , I2C2 bus or SPI bus. (Which of these communication busses is to be used depends on the NVM configuration. Please refer to the user's guide of the orderable part number for further details). To select this mode, the MCU must set bit WD_MODE_SELECT. Watchdog Question-Answer Mode provides more details. Watchdog Fail Counter and Status The watchdog includes a watchdog fail counter WD_FAIL_CNT[3:0] that increments because of bad events or decrements because of good events. Furthermore, the watchdog includes two configurable thresholds: Fail-threshold (configurable through bits WD_FAIL_TH[2:0]) Reset-threshold (configurable through bits WD_RST_TH[2:0]) When the WD_FAIL_CNT[3:0] counter value is less than or equal to the configured Watchdog-Fail threshold (WD_FAIL_TH[2:0]) and bit WD_FIRST_OK=1, the MCU can set the ENABLE_DRV bit when no other error-flags are set. When the WD_FAIL_CNT[3:0] counter value is greater than the configured Watchdog-Fail threshold (WD_FAIL_CNT[3:0] > WD_FAIL_TH[2:0]), the device clears the ENABLE_DRV bit, sets the error-flag WD_FAIL_INT, and pulls the nINT pin low. When the WD_FAIL_CNT[3:0] counter value is greater than the configured Watchdog-Fail plus Watchdog-Reset threshold (WD_FAIL_CNT[3:0] > (WD_FAIL_TH[2:0] + WD_RST_TH[2:0])) and the watchdog-reset function is enabled (configuration bit WD_RST_EN=1), the device generates a WD_ERROR trigger in the state machine (see PFSM Trigger Selections) and sets the error-flag WD_RST_INT, and pulls the nINT pin low. Unless described otherwise in the user's guide of the orderable part number, this WD_ERROR trigger in the state machine causes the TPS6593-Q1 to execute a warm-reset, during which the nRSTOUT pin pulled low, and released after a pre-configured delay time. The device clears the WD_FAIL_CNT[3:0] each time the watchdog enters the Long Window. The status bits WD_FAIL_INT and WD_RST_INT are latched until the MCU writes a ‘1’ to these bits. Overview of Watchdog Fail Counter Value Ranges and Corresponding Device Status gives an overview of the Watchdog Fail Counter value ranges and the corresponding device status. Overview of Watchdog Fail Counter Value Ranges and Corresponding Device Status Watchdog Fail Counter value WD_FAIL_CNT[3:0] Device Status WD_FAIL_CNT[3:0] ≤ WD_FAIL_TH[2:0] MCU can set the ENABLE_DRV bit if WD_FIRST_OK=1 and no other error-flags are set. WD_FAIL_TH[2:0] < WD_FAIL_CNT[3:0] ≤ (WD_FAIL_TH[2:0] + WD_RST_TH[2:0]) The device sets error-flag WD_FAIL_INT and pulls the nINT pin low. Furthermore, , the device clears the ENABLE_DRV bit. WD_FAIL_CNT[3:0] > (WD_FAIL_TH[2:0] + WD_RST_TH[2:0]) If configuration bit WD_RST_EN=1, device generates WD_ERROR trigger in the state machine and reacts as defined in the PFSM, sets the error-flag WD_RST_INT, and pulls the nINT pin low. See Summary of Interrupt Signals for the interrupt handling of WD_RST. The WD_FAIL_CNT[3:0] counter responds as follows: When the Watchdog is in the Long-Window, the WD_FAIL_CNT[3:0] is cleared to 4’b0000 A good event decrements the WD_FAIL_CNT[3:0] by one before the start of the next Window-1 A bad event increments the WD_FAIL_CNT[3:0] by one before the start of the next Window-1 Refer to Watchdog Trigger Mode and Watchdog Q&A Related Definitions respectively for definitions of good events and bad events. Watchdog Start-Up and Configuration When the device releases the nRSTOUT pin, the watchdog starts with the Long Window. This Long Window has a time interval (tLONG_WINDOW) with a default value set in bits WD_LONGWIN[7:0]. As long as the watchdog is in the Long Window, the MCU can configure the watchdog through the following register bits: WD_EN to enable or disable the watchdog WD_LONGWIN[7:0] to increase the duration of the Long-Window time-interval WD_MODE_SELECT to select the Watchdog mode (Trigger mode or Q&A Mode) WD_PWRHOLD to activate the Watchdog Disable function (more detail in ) WD_RETURN_LONGWIN to configure whether to return to Long-Window or continue to the next sequence after the completion of the current watchdog sequence (more detail in ) WD_WIN1[6:0] to configure the duration of the Window-1 time-interval WD_WIN2[6:0] to configure the duration of the Window-2 time-interval WD_RST_EN to enable or disable the watchdog-reset function WD_FAIL_TH[2:0] to configure the Watchdog-Fail threshold WD_RST_TH[2:0] to configure the Watchdog-Reset threshold WD_QA_FDBK[1:0] to configure the settings for the reference answer-generation WD_QA_LFSR[1:0] to configure the settings for the question-generation WD_QUESTION_SEED[3:0] to configure the starting-point for the 1st question-generation The device keeps the above register bit values configured by the MCU as long as the device is powered. The MCU can configure the time interval of the Long Window (tLONG_WINDOW) with the WD_LONGWIN[7:0] bits. The WD_LONGWIN[7:0] bits are defined as: 0x00: 80 ms 0x01 - 0x40: 125 ms to 8 sec, in 125-ms steps 0x41 - 0xFF: 12 sec to 772 sec, in 4-sec steps Use #GUID-349299FD-F71B-4E28-A307-921903D70A3E/SLVSE828888 and #GUID-349299FD-F71B-4E28-A307-921903D70A3E/SLVSE822625 to calculate the minimum and maximum values for the Long Window (tLONG_WINDOW) time interval when WD_LONGWIN[7:0] > 0x00: tLONG_WINDOW_MIN = WD_LONGWIN[7:0] × 0.95 tLONG_WINDOW_MAX = WD_LONGWIN[7:0] × 1.05 If the MCU software changes the duration of the Long-Window to an interval shorter than the time in which the watchdog has been in the Long-Window, the time-out function of the Long-Window does no longer operate. When the MCU clears bit WD_EN, the watchdog goes out of the Long Window and disables the watchdog. When the watchdog is deactivated in this way, the MCU can set bit WD_EN back to ‘1’ to enable the watchdog again, and the MCU can control the ENABLE_DRV bit when no other error-flags are set. The MCU must clear bit WD_PWRHOLD before setting bit WD_EN back to ‘1’ to start the watchdog in Long Window. The watchdog locks the following configuration register bits when it goes out of the Long Window and starts the first watchdog sequence: WD_WIN1[6:0] WD_WIN2[6:0] WD_LONGWIN[7:0] WD_MODE_SELECT WD_QA_FDBK[1:0], WD_QA_LFSR[1:0] and WD_QUESTION_SEED[3:0] WD_RST_EN, WD_EN, WD_FAIL_TH[2:0] and WD_RST_TH[2:0] MCU to Watchdog Synchronization In order to go out of the Long Window and start the first watchdog sequence, the MCU must do the following before elapse of the Long Window time interval: Clear bits WD_PWRHOLD (more detail in ) Apply a pulse signal with a minimum pulse-width tWD_pulse on the pre-assigned GPIO pin in the case the watchdog is configured for Trigger mode, or Write four times to WD_ANSWER[7:0] in the case the watchdog is configured for Q&A mode When the MCU fails to get the watchdog out of the Long Window before the configured Long Window time interval (tLONG_WINDOW) elapses, the device goes through a warm reset, and sets the WD_LONGWIN_TIMEOUT_INT. This bit latched until the MCU writes a ‘1’ to clear it. Watchdog Disable Function The watchdog in the TPS6593-Q1 device has a Watchdog Disable function to prevent an unwanted MCU reset in case the MCU is un-programmed or needs to be reprogrammed. In order to activate this Watchdog Disable function for an un-programmed MCU, DISABLE_WDOG pin must be asserted to a logic-high level for a time-interval longer than tWD_DIS prior to the moment the device releases the nRSTOUT pin. If the Watchdog Disable function is activated in this way, the device sets bit WD_PWRHOLD to keep the watchdog in the Long Window. The watchdog stays in the Long Window until the MCU clears the WD_PWRHOLD bit. In case the MCU needs to be reprogrammed while the watchdog monitors the correct operation of the MCU, the MCU can set bit WD_RETURN_LONGWIN to put the watchdog back in the Long Window. When the MCU set this bit, the watchdog returns to the Long Window after the current Watchdog Sequence completes. In order to make the watchdog stay in the Long Window as long as needed the MCU can either re-configure the Long Window (tLONG_WINDOW) time interval, or set the WD_PWRHOLD bit. Once the MCU starts the first watchdog sequence (as described in ), the MCU must clear bit WD_RETURN_LONGWIN before the end of the first watchdog sequence in order to continue the watchdog sequence operation. Watchdog Sequence Once the watchdog is out of the Long Window, each watchdog sequence starts with a Window-1 followed by a Window-2. The watchdog ends the current sequence and after one 20-MHz system clock cycle starts a next sequence when one of the events below occurs: The configured Window-2 time period elapses The watchdog detects a pulse signal with a minimum pulse-width tWD_pulse on the pre-assigned GPIO pin if the watchdog is used in Trigger mode The watchdog detects four times a write access to WD_ANSWER[7:0] in case the watchdog is used in Q&A mode The MCU can configure the time periods of the Window-1 (tWINDOW1) and Window-2 (tWINDOW2) with the bits WD_WIN1[6:0] and WD_WIN2[6:0] respectively, before starting the sequence. Use #GUID-601CEE28-A758-488E-9836-FEEC1D7197D3/SLVSE822895 and #GUID-601CEE28-A758-488E-9836-FEEC1D7197D3/SLVSE828785 to calculate the minimum and maximum values for the tWINDOW1 time interval. tWINDOW1_MIN = (WD_WIN1[6:0] + 1) × 0.55 × 0.95 ms tWINDOW1_MAX = (WD_WIN1[6:0] + 1) × 0.55 × 1.05 ms Use #GUID-601CEE28-A758-488E-9836-FEEC1D7197D3/SLVSE824341 and #GUID-601CEE28-A758-488E-9836-FEEC1D7197D3/SLVSE822158 to calculate the minimum and maximum values for the tWINDOW-2 time interval. tWINDOW2_MIN = (WD_WIN2[6:0] + 1) × 0.55 × 0.95 ms tWINDOW2_MAX = (WD_WIN2[6:0] + 1) × 0.55 × 1.05 ms Watchdog Trigger Mode When the TPS6593-Q1 device is configured to use the Watchdog Trigger Mode, the watchdog receives the watchdog-triggers from the MCU on the pre-assigned GPIO pin . A rising edge on this , followed by a stable logic-high level on that pin for more than the maximum pulse time, tWD_pulse(max), is a watchdog-trigger. The watchdog uses a deglitch filter with a tWD_pulse filter time and the internal 20-MHz system clock to create the internally-generated trigger pulse from the watchdog-trigger on the pre-assigned GPIO pin . The watchdog detects a good event when the watchdog-trigger comes in Window-2. The rising edge of the watchdog-trigger on the pre-assigned GPIO pin must occur for at least the tWD_pulse time before the end of Window-2 to generate such a good event. The watchdog detects a bad event when one of the following events occurs: The watchdog-trigger comes in Window-1. The rising edge of the watchdog-trigger on the pre-assigned GPIO pin must occur for at least the tWD_pulse time before the end of Window-1 to generate such a bad event. In case of this bad event, the device sets bits WD_TRIG_EARLY and WD_BAD_EVENT. No watchdog-trigger comes in Window-2. In case of this bad event (also referred to as time-out event), the device sets bits WD_TIMEOUT and WD_BAD_EVENT. Please consider that the minimum WD-pulse duration needs to meet the maximum deglitch time tWD_pulse (max). The status bit WD_BAD_EVENT is read-only. The watchdog clears the WD_BAD_EVENT status bit at the end of the watchdog-sequence. WatchDog Flow Chart and Timing Diagrams in Trigger Mode shows the flow-chart of the watchdog in Trigger mode.

Watchdog in Trigger Mode – Normal MCU Start-up with Correct Watchdog-Triggers Watchdog in Trigger Mode – MCU Does Not Send Watchdog-Triggers After Start-up Watchdog in Trigger Mode – Bad Event (Watchdog-Triggers in Window-1) After Start-up Watchdog in Trigger Mode – Bad Events (Too Short or no Trigger in Window-2) After Start-up Watchdog in Trigger Mode – Good Events (Correct Watchdog-Triggers) After Start-up, Followed by a Bad-Event (No Watchdog-Trigger in Window-2) and After That Followed by a Good Event. Watchdog Question-Answer Mode A 20220110 Added Section:Watchdog Question-Answer Modeyes When the TPS6593-Q1 device is configured to use the Watchdog Question Answer mode, the watchdog requires specific messages from the MCU in specific time intervals to detect correct operation of the MCU. The device provides a question for the MCU in WD_QUESTION[3:0] during operation. The MCU performs a fixed series of arithmetic operations on this question to calculate the required 32-bit answer. This answer is split into four answer bytes: Answer-3, Answer-2, Answer-1, and Answer-0. The MCU writes these answer bytes one byte at a time into WD_ANSWER[7:0] from the SPI or the dedicated I2C2 interface, mapped to GPIO1 and GPIO2 pins. A good event occurs when the MCU sends the correct answer-bytes calculated for the current question in the correct watchdog window and in the correct sequence. A bad event occurs when one of the events that follows occur: The MCU sends the correct answer-bytes, but not in the correct watchdog window. The MCU sends incorrect answer-bytes. The MCU returns correct answer-bytes, but in the incorrect sequence. If the MCU stops providing answer-bytes for the duration of the watchdog time-period, the watchdog detects a time-out event. This time-out event sets the WD_TIMEOUT status bit, increments the WD_FAIL_CNT[3:0] counter, and starts a new watchdog sequence. Watchdog Q&A Related Definitions A question and answer are defined as follows: Question A question is a 4-bit word (see ). The watchdog provides the question to the MCU when the MCU reads the WD_QUESTION[3:0] bits. The MCU can request each new question at the start of the watchdog sequence, but this is not required to calculate the answer. The MCU can also have a software implementation that generates the question according the circuit shown in . Nevertheless, the answer and therefore the answer-bytes are always based on the question generated inside the watchdog of the device. So, if the MCU generates an incorrect question and gives answer-bytes calculated from this incorrect question, the watchdog detects a bad event Answer An answer is a 32-bit word that is split into four answer bytes: Answer-3, Answer-2, Answer-1, and Answer-0. The watchdog receives an answer-byte when the MCU writes to the WD_ANSWER[7:0] bits. For each question, the watchdog requires four correct answer-bytes from the MCU in the correct timing and order (Answer-3, Answer-2, and Answer-1 in Window 1 in the correct sequence, and Answer-0 in Window 2) to detect a good event. The watchdog sequence in Q&A mode ends after the MCU writes the fourth answer byte (Answer-0), or after a time-out event when the Window-2 time-interval elapses. Watchdog Sequence in Q&A Mode The register WD_QUESTION_ANSW_CNT has following bits: Bit 6: Reserved Bit 5-4: WD_ANSW_CNT. These bits give the number for the next expected answer-byte Bit 3-0: WD_QUESTION. These bits give the value of the current generated question (1) For the question generation, the MCU is not required to read the question. The MCU can give correct answer-bytes Answer-3, Answer-2, Answer-1 as soon as Window-1 starts. The next watchdog sequence always starts in 1 system clock cycle after the watchdog receives the final Answer-0. (2) The MCU can put other I2C or SPI commands in-between the write-commands to WD_ANSWER[7:0] (even re-requesting the question). The insertion of other commands in-between the write-commands to WD_ANSWER[7:0] has no influence on the detection of a good event, as long as the three correct answer-bytes in Window-1 are in the correct sequence, and the fourth correct answer-byte is provided before the configured Window-2 time-interval elapses. Question Generation The watchdog uses a 4-bit question counter (QST_CNT[3:0] bits in ), and a 4-bit Markov chain to generate a 4-bit question. The MCU can read this question in the WD_QUESTION[3:0] bits. The watchdog generates a new question when the question counter increments, which only occurs when the watchdog detects a good event. The watchdog does not generate a new question when it detects a bad event or a time-out event. The question-counter provides a clock pulse to the Markov chain when it transitions from 4’b1111 to 4’b0000. The question counter and the Markov chain are set to the default value of 4’b0000 when the watchdog goes out of the Long Window. The Question-Generator is only re-initialized (starting with question 0000) at device power-up. In following situations, the MCU software needs to read the current question in order to synchronize with the Question-Generator: After MCU re-boot from a warm-reset After MCU software sets bit WD_RETURN_LONGWIN=1 to put the Watchdog back into Long Window After MCU wrote WD_EN=0, then reenable Watchdog again with WD_EN=1 shows the logic combination for the WD_QUESTION[3:0] generation. shows how the logic combination of the question-counter with the WD_ANSW_CNT[1:0] status bits generates the reference answer-bytes. Watchdog Question Generation (1) If the current value for bits (x1, x2, x3, x4) is 4'b0000, the next value for these bits (x1, x2, x3, x4) is 4'b0001, and all further question generation begins from this value. Watchdog Reference Answer Calculation Answer Comparison The 2-bit, watchdog-answer counter, WD_ANSW_CNT[1:0], counts the number of received answer-bytes and controls the generation of the reference answer-byte as shown in . At the start of each watchdog sequence, the default value of the WD_ANSW_CNT[1:0] counter is 2’b11 to indicate that the watchdog expects the MCU to write the correct Answer-3 in WD_ANSWER[7:0]. The device sets the WD_ANSW_ERR status bit as soon as one answer byte is not correct. The device clears this status bit only if the MCU writes a ‘1’ to this bit. Sequence of the 2-bit Watchdog Answer Counter The sequence of the 2-bit, watchdog answer-counter is as follows for each counter value: WD_ANSW_CNT[1:0] = 2‘b11: The watchdog calculates the reference Answer-3. A write access occurs. The MCU writes the Answer-3 byte in WD_ANSWER[7:0]. The watchdog compares the reference Answer-3 with the Answer-3 byte in WD_ANSWER[7:0]. The watchdog decrements the WD_ANSW_CNT[1:0] bits to 2b‘10 and sets the WD_ANSW_ERR status bit to 1 if the Answer-3 byte was incorrect. WD_ANSW_CNT[1:0] = 2b‘10: The watchdog calculates the reference Answer-2. A write access occurs. The MCU writes the Answer-2 byte in WD_ANSWER[7:0]. The watchdog compares the reference Answer-2 with the Answer-2 byte in WD_ANSWER[7:0].. The watchdog decrements the WD_ANSW_CNT[1:0] bits to 2b‘01 and sets the WD_ANSW_ERR status bit to 1 if the Answer-2 byte was incorrect. WD_ANSW_CNT[1:0] = 2b‘01: The watchdog calculates the reference Answer-1. A write access occurs. The MCU writes the Answer-1 byte in WD_ANSWER[7:0]. The watchdog compares the reference Answer-1 with the Answer-1 byte in WD_ANSWER[7:0].. The watchdog decrements the WD_ANSW_CNT[1:0] bits to 2b‘00 and sets the WD_ANSW_ERR status bit to 1 if the Answer-1 byte was incorrect. WD_ANSW_CNT[1:0] = 2b‘00: The watchdog calculates the reference Answer-0. A write access occurs. The MCU writes the Answer-0 byte in WD_ANSWER[7:0]. The watchdog compares the reference Answer-0 with the Answer-0 byte in WD_ANSWER[7:0]. The watchdog sets the WD_ANSW_ERR status bit to 1 if the Answer-0 byte was incorrect. The watchdog starts a new watchdog sequence and sets the WD_ANSW_CNT[1:0] to 2‘b11’. The MCU needs to clear the bit by writing a '1' to the WD_ANSW_ERR bit.

After such a good event, following events occur: The WD_FAIL_CNT[2:0] counter decrements by one at the end of the watchdog-sequence. The question-counter increments by one and the watchdog generates a new question. A bad event occurs when all answer-bytes are correct in value but not in correct timing. After such a bad event, following events occur: The WD_SEQ_ERR and WD_BAD_EVENT status bits are set if Window-1 time-interval elapses before watchdog has received Answer-3, Answer-2 and Answer-1. The WD_ANSW_EARLY and WD_BAD_EVENT status bits are set if watchdog receives all four answers in Window-1. The WD_FAIL_CNT[2:0] counter increments by one at the end of the watchdog-sequence. The question-counter does not change, and hence the watchdog does not generate a new question. A bad event occurs when one or more of the answer-bytes are not correct in value but in correct timing. After such a bad event, following events occur: The WD_ANSW_ERR and WD_BAD_EVENT status bits are set as soon as the watchdog detects an incorrect answer-byte. The WD_FAIL_CNT[2:0] counter increments by one at the end of the watchdog-sequence. The question-counter does not change, and hence the watchdog does not generate a new question. A bad event occurs when one or more of the answer-bytes are not correct in value and not in correct timing. After such a bad event, following events occur: The WD_ANSW_ERR and WD_BAD_EVENT status bits are set as soon as the watchdog detects an incorrect answer-byte. The WD_SEQ_ERR and WD_BAD_EVENT status bits are set if Window-1 time-interval elapses before watchdog has received Answer-3, Answer-2 and Answer-1. The WD_ANSW_EARLY and WD_BAD_EVENT status bits are set if watchdog receives all four answer-bytes in Window-1. The WD_FAIL_CNT[2:0] counter increments by one at the end of the watchdog-sequence. The question-counter does not change, and hence the watchdog does not generate a new question. A time-out event occurs when the device receives less than 4 answer-bytes before Window-2 time-interval elapses. After a time-out event occurs, following events occur: WD_SEQ_ERR and WD_BAD_EVENT status bits are set if Window-1 time-interval elapses before watchdog has received Answer-3, Answer-2 and Answer-1. The WD_TIMEOUT and WD_BAD_EVENT status bits are set at the end of the watchdog-sequence. The WD_FAIL_CNT[2:0] counter increments by one at the end of the watchdog-sequence. The question-counter does not change, and hence the watchdog does not generate a new question. The status bit WD_BAD_EVENT is read-only. The watchdog clears the WD_BAD_EVENT status bit at the end of the watchdog-sequence. The status bits WD_SEQ_ERR, WD_ANSW_EARLY, and WD_TIMEOUT are latched until the MCU writes a ‘1’ to these bits. If one or more of these status bits are set, the watchdog can still detect a good event in the next watchdog-sequence. These status bits are read-only. The watchdog clears the WD_BAD_EVENT status bit at the end of the watchdog-sequence. shows the flow-chart of the watchdog in Q&A mode.

This watchdog requires specific messages from the MCU in specific time intervals to detect correct operation of the MCU. The MCU can control the logic-level of the EN_DRV pin when the watchdog detects correct operation of the MCU. When the watchdog detects an incorrect operation of the MCU, the TPS6593-Q1 device pulls the EN_DRV pin low . This EN_DRV pin can be used in the application as a control-signal to deactivate the power output stages, for example a motor driver, in case of incorrect operation of the MCU. The watchdog has two different modes that are defined as follows: Trigger mode In trigger mode, the MCU applies a pulse signal with a minimum pulse width of tWD_pulse on the pre-assigned GPIO input pin to send the required watchdog trigger. To select this mode, the MCU must clear bit WD_MODE_SELECT. Watchdog Trigger Mode provides more details.

Watchdog Fail Counter and Status The watchdog includes a watchdog fail counter WD_FAIL_CNT[3:0] that increments because of bad events or decrements because of good events. Furthermore, the watchdog includes two configurable thresholds: Fail-threshold (configurable through bits WD_FAIL_TH[2:0]) Reset-threshold (configurable through bits WD_RST_TH[2:0]) When the WD_FAIL_CNT[3:0] counter value is less than or equal to the configured Watchdog-Fail threshold (WD_FAIL_TH[2:0]) and bit WD_FIRST_OK=1, the MCU can set the ENABLE_DRV bit when no other error-flags are set. When the WD_FAIL_CNT[3:0] counter value is greater than the configured Watchdog-Fail threshold (WD_FAIL_CNT[3:0] > WD_FAIL_TH[2:0]), the device clears the ENABLE_DRV bit, sets the error-flag WD_FAIL_INT, and pulls the nINT pin low. When the WD_FAIL_CNT[3:0] counter value is greater than the configured Watchdog-Fail plus Watchdog-Reset threshold (WD_FAIL_CNT[3:0] > (WD_FAIL_TH[2:0] + WD_RST_TH[2:0])) and the watchdog-reset function is enabled (configuration bit WD_RST_EN=1), the device generates a WD_ERROR trigger in the state machine (see PFSM Trigger Selections) and sets the error-flag WD_RST_INT, and pulls the nINT pin low. Unless described otherwise in the user's guide of the orderable part number, this WD_ERROR trigger in the state machine causes the TPS6593-Q1 to execute a warm-reset, during which the nRSTOUT pin pulled low, and released after a pre-configured delay time. The device clears the WD_FAIL_CNT[3:0] each time the watchdog enters the Long Window. The status bits WD_FAIL_INT and WD_RST_INT are latched until the MCU writes a ‘1’ to these bits. Overview of Watchdog Fail Counter Value Ranges and Corresponding Device Status gives an overview of the Watchdog Fail Counter value ranges and the corresponding device status. Overview of Watchdog Fail Counter Value Ranges and Corresponding Device Status Watchdog Fail Counter value WD_FAIL_CNT[3:0] Device Status WD_FAIL_CNT[3:0] ≤ WD_FAIL_TH[2:0] MCU can set the ENABLE_DRV bit if WD_FIRST_OK=1 and no other error-flags are set. WD_FAIL_TH[2:0] < WD_FAIL_CNT[3:0] ≤ (WD_FAIL_TH[2:0] + WD_RST_TH[2:0]) The device sets error-flag WD_FAIL_INT and pulls the nINT pin low. Furthermore, , the device clears the ENABLE_DRV bit. WD_FAIL_CNT[3:0] > (WD_FAIL_TH[2:0] + WD_RST_TH[2:0]) If configuration bit WD_RST_EN=1, device generates WD_ERROR trigger in the state machine and reacts as defined in the PFSM, sets the error-flag WD_RST_INT, and pulls the nINT pin low. See Summary of Interrupt Signals for the interrupt handling of WD_RST. The WD_FAIL_CNT[3:0] counter responds as follows: When the Watchdog is in the Long-Window, the WD_FAIL_CNT[3:0] is cleared to 4’b0000 A good event decrements the WD_FAIL_CNT[3:0] by one before the start of the next Window-1 A bad event increments the WD_FAIL_CNT[3:0] by one before the start of the next Window-1 Refer to Watchdog Trigger Mode and Watchdog Q&A Related Definitions respectively for definitions of good events and bad events. Watchdog Fail Counter and Status The watchdog includes a watchdog fail counter WD_FAIL_CNT[3:0] that increments because of bad events or decrements because of good events. Furthermore, the watchdog includes two configurable thresholds: Fail-threshold (configurable through bits WD_FAIL_TH[2:0]) Reset-threshold (configurable through bits WD_RST_TH[2:0]) When the WD_FAIL_CNT[3:0] counter value is less than or equal to the configured Watchdog-Fail threshold (WD_FAIL_TH[2:0]) and bit WD_FIRST_OK=1, the MCU can set the ENABLE_DRV bit when no other error-flags are set. When the WD_FAIL_CNT[3:0] counter value is greater than the configured Watchdog-Fail threshold (WD_FAIL_CNT[3:0] > WD_FAIL_TH[2:0]), the device clears the ENABLE_DRV bit, sets the error-flag WD_FAIL_INT, and pulls the nINT pin low. When the WD_FAIL_CNT[3:0] counter value is greater than the configured Watchdog-Fail plus Watchdog-Reset threshold (WD_FAIL_CNT[3:0] > (WD_FAIL_TH[2:0] + WD_RST_TH[2:0])) and the watchdog-reset function is enabled (configuration bit WD_RST_EN=1), the device generates a WD_ERROR trigger in the state machine (see PFSM Trigger Selections) and sets the error-flag WD_RST_INT, and pulls the nINT pin low. Unless described otherwise in the user's guide of the orderable part number, this WD_ERROR trigger in the state machine causes the TPS6593-Q1 to execute a warm-reset, during which the nRSTOUT pin pulled low, and released after a pre-configured delay time. The device clears the WD_FAIL_CNT[3:0] each time the watchdog enters the Long Window. The status bits WD_FAIL_INT and WD_RST_INT are latched until the MCU writes a ‘1’ to these bits.

Watchdog Question-Answer Mode A 20220110 Added Section:Watchdog Question-Answer Modeyes When the TPS6593-Q1 device is configured to use the Watchdog Question Answer mode, the watchdog requires specific messages from the MCU in specific time intervals to detect correct operation of the MCU. The device provides a question for the MCU in WD_QUESTION[3:0] during operation. The MCU performs a fixed series of arithmetic operations on this question to calculate the required 32-bit answer. This answer is split into four answer bytes: Answer-3, Answer-2, Answer-1, and Answer-0. The MCU writes these answer bytes one byte at a time into WD_ANSWER[7:0] from the SPI or the dedicated I2C2 interface, mapped to GPIO1 and GPIO2 pins. A good event occurs when the MCU sends the correct answer-bytes calculated for the current question in the correct watchdog window and in the correct sequence. A bad event occurs when one of the events that follows occur: The MCU sends the correct answer-bytes, but not in the correct watchdog window. The MCU sends incorrect answer-bytes. The MCU returns correct answer-bytes, but in the incorrect sequence. If the MCU stops providing answer-bytes for the duration of the watchdog time-period, the watchdog detects a time-out event. This time-out event sets the WD_TIMEOUT status bit, increments the WD_FAIL_CNT[3:0] counter, and starts a new watchdog sequence. Watchdog Q&A Related Definitions A question and answer are defined as follows: Question A question is a 4-bit word (see ). The watchdog provides the question to the MCU when the MCU reads the WD_QUESTION[3:0] bits. The MCU can request each new question at the start of the watchdog sequence, but this is not required to calculate the answer. The MCU can also have a software implementation that generates the question according the circuit shown in . Nevertheless, the answer and therefore the answer-bytes are always based on the question generated inside the watchdog of the device. So, if the MCU generates an incorrect question and gives answer-bytes calculated from this incorrect question, the watchdog detects a bad event Answer An answer is a 32-bit word that is split into four answer bytes: Answer-3, Answer-2, Answer-1, and Answer-0. The watchdog receives an answer-byte when the MCU writes to the WD_ANSWER[7:0] bits. For each question, the watchdog requires four correct answer-bytes from the MCU in the correct timing and order (Answer-3, Answer-2, and Answer-1 in Window 1 in the correct sequence, and Answer-0 in Window 2) to detect a good event. The watchdog sequence in Q&A mode ends after the MCU writes the fourth answer byte (Answer-0), or after a time-out event when the Window-2 time-interval elapses. Watchdog Sequence in Q&A Mode The register WD_QUESTION_ANSW_CNT has following bits: Bit 6: Reserved Bit 5-4: WD_ANSW_CNT. These bits give the number for the next expected answer-byte Bit 3-0: WD_QUESTION. These bits give the value of the current generated question (1) For the question generation, the MCU is not required to read the question. The MCU can give correct answer-bytes Answer-3, Answer-2, Answer-1 as soon as Window-1 starts. The next watchdog sequence always starts in 1 system clock cycle after the watchdog receives the final Answer-0. (2) The MCU can put other I2C or SPI commands in-between the write-commands to WD_ANSWER[7:0] (even re-requesting the question). The insertion of other commands in-between the write-commands to WD_ANSWER[7:0] has no influence on the detection of a good event, as long as the three correct answer-bytes in Window-1 are in the correct sequence, and the fourth correct answer-byte is provided before the configured Window-2 time-interval elapses. Question Generation The watchdog uses a 4-bit question counter (QST_CNT[3:0] bits in ), and a 4-bit Markov chain to generate a 4-bit question. The MCU can read this question in the WD_QUESTION[3:0] bits. The watchdog generates a new question when the question counter increments, which only occurs when the watchdog detects a good event. The watchdog does not generate a new question when it detects a bad event or a time-out event. The question-counter provides a clock pulse to the Markov chain when it transitions from 4’b1111 to 4’b0000. The question counter and the Markov chain are set to the default value of 4’b0000 when the watchdog goes out of the Long Window. The Question-Generator is only re-initialized (starting with question 0000) at device power-up. In following situations, the MCU software needs to read the current question in order to synchronize with the Question-Generator: After MCU re-boot from a warm-reset After MCU software sets bit WD_RETURN_LONGWIN=1 to put the Watchdog back into Long Window After MCU wrote WD_EN=0, then reenable Watchdog again with WD_EN=1 shows the logic combination for the WD_QUESTION[3:0] generation. shows how the logic combination of the question-counter with the WD_ANSW_CNT[1:0] status bits generates the reference answer-bytes. Watchdog Question Generation (1) If the current value for bits (x1, x2, x3, x4) is 4'b0000, the next value for these bits (x1, x2, x3, x4) is 4'b0001, and all further question generation begins from this value. Watchdog Reference Answer Calculation Answer Comparison The 2-bit, watchdog-answer counter, WD_ANSW_CNT[1:0], counts the number of received answer-bytes and controls the generation of the reference answer-byte as shown in . At the start of each watchdog sequence, the default value of the WD_ANSW_CNT[1:0] counter is 2’b11 to indicate that the watchdog expects the MCU to write the correct Answer-3 in WD_ANSWER[7:0]. The device sets the WD_ANSW_ERR status bit as soon as one answer byte is not correct. The device clears this status bit only if the MCU writes a ‘1’ to this bit. Sequence of the 2-bit Watchdog Answer Counter The sequence of the 2-bit, watchdog answer-counter is as follows for each counter value: WD_ANSW_CNT[1:0] = 2‘b11: The watchdog calculates the reference Answer-3. A write access occurs. The MCU writes the Answer-3 byte in WD_ANSWER[7:0]. The watchdog compares the reference Answer-3 with the Answer-3 byte in WD_ANSWER[7:0]. The watchdog decrements the WD_ANSW_CNT[1:0] bits to 2b‘10 and sets the WD_ANSW_ERR status bit to 1 if the Answer-3 byte was incorrect. WD_ANSW_CNT[1:0] = 2b‘10: The watchdog calculates the reference Answer-2. A write access occurs. The MCU writes the Answer-2 byte in WD_ANSWER[7:0]. The watchdog compares the reference Answer-2 with the Answer-2 byte in WD_ANSWER[7:0].. The watchdog decrements the WD_ANSW_CNT[1:0] bits to 2b‘01 and sets the WD_ANSW_ERR status bit to 1 if the Answer-2 byte was incorrect. WD_ANSW_CNT[1:0] = 2b‘01: The watchdog calculates the reference Answer-1. A write access occurs. The MCU writes the Answer-1 byte in WD_ANSWER[7:0]. The watchdog compares the reference Answer-1 with the Answer-1 byte in WD_ANSWER[7:0].. The watchdog decrements the WD_ANSW_CNT[1:0] bits to 2b‘00 and sets the WD_ANSW_ERR status bit to 1 if the Answer-1 byte was incorrect. WD_ANSW_CNT[1:0] = 2b‘00: The watchdog calculates the reference Answer-0. A write access occurs. The MCU writes the Answer-0 byte in WD_ANSWER[7:0]. The watchdog compares the reference Answer-0 with the Answer-0 byte in WD_ANSWER[7:0]. The watchdog sets the WD_ANSW_ERR status bit to 1 if the Answer-0 byte was incorrect. The watchdog starts a new watchdog sequence and sets the WD_ANSW_CNT[1:0] to 2‘b11’. The MCU needs to clear the bit by writing a '1' to the WD_ANSW_ERR bit.

After such a good event, following events occur: The WD_FAIL_CNT[2:0] counter decrements by one at the end of the watchdog-sequence. The question-counter increments by one and the watchdog generates a new question. A bad event occurs when all answer-bytes are correct in value but not in correct timing. After such a bad event, following events occur: The WD_SEQ_ERR and WD_BAD_EVENT status bits are set if Window-1 time-interval elapses before watchdog has received Answer-3, Answer-2 and Answer-1. The WD_ANSW_EARLY and WD_BAD_EVENT status bits are set if watchdog receives all four answers in Window-1. The WD_FAIL_CNT[2:0] counter increments by one at the end of the watchdog-sequence. The question-counter does not change, and hence the watchdog does not generate a new question. A bad event occurs when one or more of the answer-bytes are not correct in value but in correct timing. After such a bad event, following events occur: The WD_ANSW_ERR and WD_BAD_EVENT status bits are set as soon as the watchdog detects an incorrect answer-byte. The WD_FAIL_CNT[2:0] counter increments by one at the end of the watchdog-sequence. The question-counter does not change, and hence the watchdog does not generate a new question. A bad event occurs when one or more of the answer-bytes are not correct in value and not in correct timing. After such a bad event, following events occur: The WD_ANSW_ERR and WD_BAD_EVENT status bits are set as soon as the watchdog detects an incorrect answer-byte. The WD_SEQ_ERR and WD_BAD_EVENT status bits are set if Window-1 time-interval elapses before watchdog has received Answer-3, Answer-2 and Answer-1. The WD_ANSW_EARLY and WD_BAD_EVENT status bits are set if watchdog receives all four answer-bytes in Window-1. The WD_FAIL_CNT[2:0] counter increments by one at the end of the watchdog-sequence. The question-counter does not change, and hence the watchdog does not generate a new question. A time-out event occurs when the device receives less than 4 answer-bytes before Window-2 time-interval elapses. After a time-out event occurs, following events occur: WD_SEQ_ERR and WD_BAD_EVENT status bits are set if Window-1 time-interval elapses before watchdog has received Answer-3, Answer-2 and Answer-1. The WD_TIMEOUT and WD_BAD_EVENT status bits are set at the end of the watchdog-sequence. The WD_FAIL_CNT[2:0] counter increments by one at the end of the watchdog-sequence. The question-counter does not change, and hence the watchdog does not generate a new question. The status bit WD_BAD_EVENT is read-only. The watchdog clears the WD_BAD_EVENT status bit at the end of the watchdog-sequence. The status bits WD_SEQ_ERR, WD_ANSW_EARLY, and WD_TIMEOUT are latched until the MCU writes a ‘1’ to these bits. If one or more of these status bits are set, the watchdog can still detect a good event in the next watchdog-sequence. These status bits are read-only. The watchdog clears the WD_BAD_EVENT status bit at the end of the watchdog-sequence. shows the flow-chart of the watchdog in Q&A mode.

Watchdog Q&A Related Definitions A question and answer are defined as follows: Question A question is a 4-bit word (see ). The watchdog provides the question to the MCU when the MCU reads the WD_QUESTION[3:0] bits. The MCU can request each new question at the start of the watchdog sequence, but this is not required to calculate the answer. The MCU can also have a software implementation that generates the question according the circuit shown in . Nevertheless, the answer and therefore the answer-bytes are always based on the question generated inside the watchdog of the device. So, if the MCU generates an incorrect question and gives answer-bytes calculated from this incorrect question, the watchdog detects a bad event Answer An answer is a 32-bit word that is split into four answer bytes: Answer-3, Answer-2, Answer-1, and Answer-0. The watchdog receives an answer-byte when the MCU writes to the WD_ANSWER[7:0] bits. For each question, the watchdog requires four correct answer-bytes from the MCU in the correct timing and order (Answer-3, Answer-2, and Answer-1 in Window 1 in the correct sequence, and Answer-0 in Window 2) to detect a good event. The watchdog sequence in Q&A mode ends after the MCU writes the fourth answer byte (Answer-0), or after a time-out event when the Window-2 time-interval elapses. Watchdog Sequence in Q&A Mode The register WD_QUESTION_ANSW_CNT has following bits: Bit 6: Reserved Bit 5-4: WD_ANSW_CNT. These bits give the number for the next expected answer-byte Bit 3-0: WD_QUESTION. These bits give the value of the current generated question (1) For the question generation, the MCU is not required to read the question. The MCU can give correct answer-bytes Answer-3, Answer-2, Answer-1 as soon as Window-1 starts. The next watchdog sequence always starts in 1 system clock cycle after the watchdog receives the final Answer-0. (2) The MCU can put other I2C or SPI commands in-between the write-commands to WD_ANSWER[7:0] (even re-requesting the question). The insertion of other commands in-between the write-commands to WD_ANSWER[7:0] has no influence on the detection of a good event, as long as the three correct answer-bytes in Window-1 are in the correct sequence, and the fourth correct answer-byte is provided before the configured Window-2 time-interval elapses.

So, if the MCU generates an incorrect question and gives answer-bytes calculated from this incorrect question, the watchdog detects a bad event Answer An answer is a 32-bit word that is split into four answer bytes: Answer-3, Answer-2, Answer-1, and Answer-0. The watchdog receives an answer-byte when the MCU writes to the WD_ANSWER[7:0] bits. For each question, the watchdog requires four correct answer-bytes from the MCU in the correct timing and order (Answer-3, Answer-2, and Answer-1 in Window 1 in the correct sequence, and Answer-0 in Window 2) to detect a good event. The watchdog sequence in Q&A mode ends after the MCU writes the fourth answer byte (Answer-0), or after a time-out event when the Window-2 time-interval elapses. Watchdog Sequence in Q&A Mode The register WD_QUESTION_ANSW_CNT has following bits: Bit 6: Reserved Bit 5-4: WD_ANSW_CNT. These bits give the number for the next expected answer-byte Bit 3-0: WD_QUESTION. These bits give the value of the current generated question (1) For the question generation, the MCU is not required to read the question. The MCU can give correct answer-bytes Answer-3, Answer-2, Answer-1 as soon as Window-1 starts. The next watchdog sequence always starts in 1 system clock cycle after the watchdog receives the final Answer-0. (2) The MCU can put other I2C or SPI commands in-between the write-commands to WD_ANSWER[7:0] (even re-requesting the question). The insertion of other commands in-between the write-commands to WD_ANSWER[7:0] has no influence on the detection of a good event, as long as the three correct answer-bytes in Window-1 are in the correct sequence, and the fourth correct answer-byte is provided before the configured Window-2 time-interval elapses. A question and answer are defined as follows: Question A question is a 4-bit word (see ). The watchdog provides the question to the MCU when the MCU reads the WD_QUESTION[3:0] bits. The MCU can request each new question at the start of the watchdog sequence, but this is not required to calculate the answer.

The MCU can read this question in the WD_QUESTION[3:0] bits. The watchdog generates a new question when the question counter increments, which only occurs when the watchdog detects a good event. The watchdog does not generate a new question when it detects a bad event or a time-out event. The question-counter provides a clock pulse to the Markov chain when it transitions from 4’b1111 to 4’b0000. The question counter and the Markov chain are set to the default value of 4’b0000 when the watchdog goes out of the Long Window. The Question-Generator is only re-initialized (starting with question 0000) at device power-up. In following situations, the MCU software needs to read the current question in order to synchronize with the Question-Generator: After MCU re-boot from a warm-reset After MCU software sets bit WD_RETURN_LONGWIN=1 to put the Watchdog back into Long Window After MCU wrote WD_EN=0, then reenable Watchdog again with WD_EN=1 shows the logic combination for the WD_QUESTION[3:0] generation. shows how the logic combination of the question-counter with the WD_ANSW_CNT[1:0] status bits generates the reference answer-bytes. Watchdog Question Generation (1) If the current value for bits (x1, x2, x3, x4) is 4'b0000, the next value for these bits (x1, x2, x3, x4) is 4'b0001, and all further question generation begins from this value.

Watchdog Reference Answer Calculation Watchdog Reference Answer Calculation Answer Comparison The 2-bit, watchdog-answer counter, WD_ANSW_CNT[1:0], counts the number of received answer-bytes and controls the generation of the reference answer-byte as shown in . At the start of each watchdog sequence, the default value of the WD_ANSW_CNT[1:0] counter is 2’b11 to indicate that the watchdog expects the MCU to write the correct Answer-3 in WD_ANSWER[7:0]. The device sets the WD_ANSW_ERR status bit as soon as one answer byte is not correct. The device clears this status bit only if the MCU writes a ‘1’ to this bit. Sequence of the 2-bit Watchdog Answer Counter The sequence of the 2-bit, watchdog answer-counter is as follows for each counter value: WD_ANSW_CNT[1:0] = 2‘b11: The watchdog calculates the reference Answer-3. A write access occurs. The MCU writes the Answer-3 byte in WD_ANSWER[7:0]. The watchdog compares the reference Answer-3 with the Answer-3 byte in WD_ANSWER[7:0]. The watchdog decrements the WD_ANSW_CNT[1:0] bits to 2b‘10 and sets the WD_ANSW_ERR status bit to 1 if the Answer-3 byte was incorrect. WD_ANSW_CNT[1:0] = 2b‘10: The watchdog calculates the reference Answer-2. A write access occurs. The MCU writes the Answer-2 byte in WD_ANSWER[7:0]. The watchdog compares the reference Answer-2 with the Answer-2 byte in WD_ANSWER[7:0].. The watchdog decrements the WD_ANSW_CNT[1:0] bits to 2b‘01 and sets the WD_ANSW_ERR status bit to 1 if the Answer-2 byte was incorrect. WD_ANSW_CNT[1:0] = 2b‘01: The watchdog calculates the reference Answer-1. A write access occurs. The MCU writes the Answer-1 byte in WD_ANSWER[7:0]. The watchdog compares the reference Answer-1 with the Answer-1 byte in WD_ANSWER[7:0].. The watchdog decrements the WD_ANSW_CNT[1:0] bits to 2b‘00 and sets the WD_ANSW_ERR status bit to 1 if the Answer-1 byte was incorrect. WD_ANSW_CNT[1:0] = 2b‘00: The watchdog calculates the reference Answer-0. A write access occurs. The MCU writes the Answer-0 byte in WD_ANSWER[7:0]. The watchdog compares the reference Answer-0 with the Answer-0 byte in WD_ANSWER[7:0]. The watchdog sets the WD_ANSW_ERR status bit to 1 if the Answer-0 byte was incorrect. The watchdog starts a new watchdog sequence and sets the WD_ANSW_CNT[1:0] to 2‘b11’. The MCU needs to clear the bit by writing a '1' to the WD_ANSW_ERR bit.

After such a good event, following events occur: The WD_FAIL_CNT[2:0] counter decrements by one at the end of the watchdog-sequence. The question-counter increments by one and the watchdog generates a new question. A bad event occurs when all answer-bytes are correct in value but not in correct timing. After such a bad event, following events occur: The WD_SEQ_ERR and WD_BAD_EVENT status bits are set if Window-1 time-interval elapses before watchdog has received Answer-3, Answer-2 and Answer-1. The WD_ANSW_EARLY and WD_BAD_EVENT status bits are set if watchdog receives all four answers in Window-1. The WD_FAIL_CNT[2:0] counter increments by one at the end of the watchdog-sequence. The question-counter does not change, and hence the watchdog does not generate a new question. A bad event occurs when one or more of the answer-bytes are not correct in value but in correct timing. After such a bad event, following events occur: The WD_ANSW_ERR and WD_BAD_EVENT status bits are set as soon as the watchdog detects an incorrect answer-byte. The WD_FAIL_CNT[2:0] counter increments by one at the end of the watchdog-sequence. The question-counter does not change, and hence the watchdog does not generate a new question. A bad event occurs when one or more of the answer-bytes are not correct in value and not in correct timing. After such a bad event, following events occur: The WD_ANSW_ERR and WD_BAD_EVENT status bits are set as soon as the watchdog detects an incorrect answer-byte. The WD_SEQ_ERR and WD_BAD_EVENT status bits are set if Window-1 time-interval elapses before watchdog has received Answer-3, Answer-2 and Answer-1. The WD_ANSW_EARLY and WD_BAD_EVENT status bits are set if watchdog receives all four answer-bytes in Window-1. The WD_FAIL_CNT[2:0] counter increments by one at the end of the watchdog-sequence. The question-counter does not change, and hence the watchdog does not generate a new question. A time-out event occurs when the device receives less than 4 answer-bytes before Window-2 time-interval elapses. After a time-out event occurs, following events occur: WD_SEQ_ERR and WD_BAD_EVENT status bits are set if Window-1 time-interval elapses before watchdog has received Answer-3, Answer-2 and Answer-1. The WD_TIMEOUT and WD_BAD_EVENT status bits are set at the end of the watchdog-sequence. The WD_FAIL_CNT[2:0] counter increments by one at the end of the watchdog-sequence. The question-counter does not change, and hence the watchdog does not generate a new question. The status bit WD_BAD_EVENT is read-only. The watchdog clears the WD_BAD_EVENT status bit at the end of the watchdog-sequence. The status bits WD_SEQ_ERR, WD_ANSW_EARLY, and WD_TIMEOUT are latched until the MCU writes a ‘1’ to these bits. If one or more of these status bits are set, the watchdog can still detect a good event in the next watchdog-sequence. These status bits are read-only. The watchdog clears the WD_BAD_EVENT status bit at the end of the watchdog-sequence. shows the flow-chart of the watchdog in Q&A mode.

After such a good event, following events occur: The WD_FAIL_CNT[2:0] counter decrements by one at the end of the watchdog-sequence. The question-counter increments by one and the watchdog generates a new question. A bad event occurs when all answer-bytes are correct in value but not in correct timing. After such a bad event, following events occur: The WD_SEQ_ERR and WD_BAD_EVENT status bits are set if Window-1 time-interval elapses before watchdog has received Answer-3, Answer-2 and Answer-1. The WD_ANSW_EARLY and WD_BAD_EVENT status bits are set if watchdog receives all four answers in Window-1. The WD_FAIL_CNT[2:0] counter increments by one at the end of the watchdog-sequence. The question-counter does not change, and hence the watchdog does not generate a new question. A bad event occurs when one or more of the answer-bytes are not correct in value but in correct timing. After such a bad event, following events occur: The WD_ANSW_ERR and WD_BAD_EVENT status bits are set as soon as the watchdog detects an incorrect answer-byte. The WD_FAIL_CNT[2:0] counter increments by one at the end of the watchdog-sequence. The question-counter does not change, and hence the watchdog does not generate a new question. A bad event occurs when one or more of the answer-bytes are not correct in value and not in correct timing. After such a bad event, following events occur: The WD_ANSW_ERR and WD_BAD_EVENT status bits are set as soon as the watchdog detects an incorrect answer-byte. The WD_SEQ_ERR and WD_BAD_EVENT status bits are set if Window-1 time-interval elapses before watchdog has received Answer-3, Answer-2 and Answer-1. The WD_ANSW_EARLY and WD_BAD_EVENT status bits are set if watchdog receives all four answer-bytes in Window-1. The WD_FAIL_CNT[2:0] counter increments by one at the end of the watchdog-sequence. The question-counter does not change, and hence the watchdog does not generate a new question. A time-out event occurs when the device receives less than 4 answer-bytes before Window-2 time-interval elapses. After a time-out event occurs, following events occur: WD_SEQ_ERR and WD_BAD_EVENT status bits are set if Window-1 time-interval elapses before watchdog has received Answer-3, Answer-2 and Answer-1. The WD_TIMEOUT and WD_BAD_EVENT status bits are set at the end of the watchdog-sequence. The WD_FAIL_CNT[2:0] counter increments by one at the end of the watchdog-sequence. The question-counter does not change, and hence the watchdog does not generate a new question. The status bit WD_BAD_EVENT is read-only. The watchdog clears the WD_BAD_EVENT status bit at the end of the watchdog-sequence. The status bits WD_SEQ_ERR, WD_ANSW_EARLY, and WD_TIMEOUT are latched until the MCU writes a ‘1’ to these bits. If one or more of these status bits are set, the watchdog can still detect a good event in the next watchdog-sequence. These status bits are read-only. The watchdog clears the WD_BAD_EVENT status bit at the end of the watchdog-sequence. shows the flow-chart of the watchdog in Q&A mode.

The WD_SEQ_ERR and WD_BAD_EVENT status bits are set if Window-1 time-interval elapses before watchdog has received Answer-3, Answer-2 and Answer-1. The WD_ANSW_EARLY and WD_BAD_EVENT status bits are set if watchdog receives all four answer-bytes in Window-1. The WD_FAIL_CNT[2:0] counter increments by one at the end of the watchdog-sequence. The question-counter does not change, and hence the watchdog does not generate a new question. A time-out event occurs when the device receives less than 4 answer-bytes before Window-2 time-interval elapses. After a time-out event occurs, following events occur: WD_SEQ_ERR and WD_BAD_EVENT status bits are set if Window-1 time-interval elapses before watchdog has received Answer-3, Answer-2 and Answer-1. The WD_TIMEOUT and WD_BAD_EVENT status bits are set at the end of the watchdog-sequence. The WD_FAIL_CNT[2:0] counter increments by one at the end of the watchdog-sequence. The question-counter does not change, and hence the watchdog does not generate a new question. The status bit WD_BAD_EVENT is read-only. The watchdog clears the WD_BAD_EVENT status bit at the end of the watchdog-sequence. The status bits WD_SEQ_ERR, WD_ANSW_EARLY, and WD_TIMEOUT are latched until the MCU writes a ‘1’ to these bits. If one or more of these status bits are set, the watchdog can still detect a good event in the next watchdog-sequence. These status bits are read-only. The watchdog clears the WD_BAD_EVENT status bit at the end of the watchdog-sequence. shows the flow-chart of the watchdog in Q&A mode. Flow Chart for WatchDog in Q&A Mode The watchdog sequence events are as follows for the different scenarios listed: A good event occurs when all answer bytes are correct in value and timing. After such a good event, following events occur: The WD_FAIL_CNT[2:0] counter decrements by one at the end of the watchdog-sequence. The question-counter increments by one and the watchdog generates a new question. A bad event occurs when all answer-bytes are correct in value but not in correct timing.

Added Section: Error Signal Monitor (ESM)yes The TPS6593-Q1 device has two error signal monitor (ESMs): one ESM_MCU to monitor the MCU error output signal at the nERR_MCU input pin, and one ESM_SoC to monitor the SoC error output signal at the nERR_SoC input pin. At device start-up, the ESM_MCU and ESM_SoC can be enabled or deactivated through configuration bits ESM_MCU_EN and ESM_SOC_EN. The values for these configuration bits are stored in the NVM memory of the device. To start the enabled ESM, the MCU sets the start bits ESM_MCU_START or ESM_SOC_START for the corresponding ESM through software after the system is powered up and the initial software configuration is completed. If the MCU clears a start bit, the ESM stops monitoring its input pin. The MCU can set the ENABLE_DRV bit only when the MCU has either started or deactivated the ESM. When the corresponding ESM is started, the following configuration registers are write protected and can only be read: Configuration registers write-protected by the ESM_MCU_START register bit: ESM_MCU_DELAY1_REG ESM_MCU_DELAY2_REG ESM_MCU_MODE_CFG ESM_MCU_HMAX_REG ESM_MCU_HMIN_REG ESM_MCU_LMAX_REG ESM_MCU_LMIN_REG Configuration registers write-protected by the ESM_SOC_START register bit: ESM_SOC_DELAY1_REG ESM_SOC_DELAY2_REG ESM_SOC_MODE_CFG ESM_SOC_HMAX_REG ESM_SOC_HMIN_REG ESM_SOC_LMAX_REG ESM_SOC_LMIN_REG The ESM uses a deglitch-filter with deglitch-time tdegl_ESMx to monitor its related input pin. The MCU can configure the ESM in two different modes that are defined as follows: Level Mode the ESM detects an ESM-error when the input pin remains low for a time equal to or longer than the deglitch-time tdegl_ESMx. To select this mode for the ESM_MCU, the MCU must clear bit ESM_MCU_MODE. To select this mode for the ESM_SoC, the MCU must clear bit ESM_SOC_MODE. See for further detail. PWM Mode the ESM monitors a PWM signal at its input pin. The ESM detects a bad-event when the frequency or duty cycle of the PWM input signal deviates from the expected signal. The ESM detects a good-event when the frequency and duty cycle of the PWM signal match with the expected signal for one signal period. The ESM has an error-counter (ESM_MCU_ERR_CNT[4:0] or ESM_SOC_ERR_CNT[4:0]), which increments with +2 after each bad-event, and decrements with -1 after each good-event. The ESM detects an ESM-error when the error-counter value is more than its related threshold value. To select this mode for the ESM_MCU, the MCU must set bit ESM_MCU_MODE. To select this mode for the ESM_SoC, the MCU must set bit ESM_SOC_MODE. See for further details. The MCU can configure each ESM as long as its related start bit is cleared to 0 (bit ESM_MCU_START or ESM_SOC_START). As soon as the MCU sets a start bit, the device sets a write-protection on the configuration registers of the related ESM except the related start bits ESM_MCU_START and ESM_SOC_START. ESM Error-Handling Procedure Each ESM has two of its own configurable delay-timers that are reset when the device clears the respective ESM_x_START bit. Below steps describe the procedure through which the ESM goes in case it detects an ESM-error: If the respective mask bit ESM_x_PIN_MASK=0, the device sets interrupt bit ESM_MCU_PIN_INT or ESM_SOC_PIN_INT, and pulls the nINT pin low. The ESM starts the delay-1 timer (configurable through related ESM_MCU_DELAY1[7:0] or ESM_SOC_DELAY1[7:0] bits). If the ESM-error is no longer present and MCU has cleared the related interrupt bit ESM_MCU_PIN_INT or ESM_SOC_PIN_INT before the delay-1 timer elapses, the device releases the nINTpin, the ESM resets the delay-1 and delay-2 timers and continues to monitor its input pin. If the ESM-error is still present, or if MCU has not cleared the related interrupt bit ESM_MCU_PIN_INT or ESM_SOC_PIN_INT, and the delay-1 timer elapses, then the ESM clears the ENABLE_DRV bit if bit ESM_MCU_ENDRV=1 or if bit ESM_SOC_ENDRV=1. If the delay-2 timer (configurable through related ESM_MCU_DELAY2[7:0] or ESM_SOC_DELAY2[7:0] bits) is set to 0, then the ESM skips steps 6 of this list, and performs step 7. If the delay-2 timer is not set to 0, then: ESM starts the delay-2 timer, If ESM_MCU_FAIL_MASK = 0, the device sets interrupt bit ESM_MCU_FAIL_INT and pulls the nINT pin low and starts the delay-2 timer. If ESM_SOC_FAIL_MASK = 0, the device sets interrupt bit ESM_SOC_FAIL_INT, pulls the nINT pin low and starts the delay-2 timer. If the ESM-error is no longer present and the MCU has cleared the related interrupt bits listed below before the delay-2 timer elapses, the device releases the nINTpin, the ESM resets the delay-1 and delay-2 timers and continues to monitor its input pin: ESM_MCU_PIN_INT (and ESM_MCU_FAIL_INT if set in step 6), or ESM_SOC_PIN_INT (and ESM_SOC_FAIL_INT if set in step 6) If the ESM-error is still present, or if MCU has not cleared the related interrupt bits ESM_MCU_PIN_INT and ESM_MCU_FAIL_INT , or ESM_SOC_PIN_INT and ESM_SOC_FAIL_INT, and the delay-2 timer elapses, then : For ESM_MCU, the device: clears the ESM_MCU_START BIT sets interrupt bits ESM_MCU_FAIL_INT and ESM_MCU_RST_INT, which the device handles as an ESM_MCU_RST trigger for FSM, described in Summary of Interrupt Signals After this trigger handling completes, the device re-initializes the ESM_MCU For ESM_SoC, the device: clears the ESM_SOC_START bit sets interrupt bits ESM_SOC_FAIL_INT and ESM_SOC_RST_INT, which the device handles as an ESM_SOC_RST trigger for FSM, described in Summary of Interrupt Signals After this trigger handling completes, the device re-initializes the ESM_SoC ESM_MCU_DELAY1[7:0] and ESM_SOC_DELAY1[7:0] set the delay-1 time-interval (tDELAY-1) for the related ESM_MCU or ESM_SoC. Use #GUID-DF6532B4-B17E-4C92-B12D-2D4021966C59/SLVSE82707 and #GUID-DF6532B4-B17E-4C92-B12D-2D4021966C59/SLVSE827308 to calculate the worst-case values for the tDELAY-1: Min. tDELAY-1 = (ESM_x_DELAY1[7:0] × 2.048 ms) × 0.95 Max. tDELAY-1 = (ESM _x_DELAY1[7:0] × 2.048 ms) × 1.05 , in which x stands for either MCU or SoC. ESM_MCU_DELAY2[7:0] or ESM_SOC_DELAY2[7:0] bits set the delay-2 time-interval (tDELAY-2) for the related ESM_MCU or ESM_SoC.

Level Mode In Level Mode, after MCU has set the start bit (bit ESM_MCU_START or bit ESM_SOC_START), the ESM monitors its nERR_MCU or nERR_SoC input pin. Each ESM detects an ESM-error when the voltage level on its input pin remains low for a time equal or longer than the deglitch-time tdegl_ESMx. When an ESM_x detects an ESM-error, it starts the ESM Error-Handling procedure as described in . The Error-Handling Procedure is stopped if, before elapse of the delay-1 or delay-2 interval, the voltage level on the input pin remains high for a time equal or longer than the deglitch-time tdegl_ESMx and the MCU clears all corresponding interrupt bits. If the ESM-error persists such that the configured delay-1 and delay-2 times elapse, the ESM sends a ESM_x_RST trigger to the PFSM and the device clear the ESM_x_START bit. After the PFSM completes the handling of the ESM_x_RST trigger, the device re-initializes the ESM. For a complete overview on how the ESM works in Level Mode, please refer to the flow-chart in .

If the input signal remains low after exceeding the maximum low-pulse time-threshold (tLOW_MAX_TH), the ESM detects a bad event and the low-pulse duration counter reinitializes. Each time the signal further exceeds the maximum threshold, the ESM detects a bad event. On the next rising edge on the input signal, the ESM starts the high-pulse time-duration monitoring After a rising edge, the ESM starts monitoring the high-pulse time-duration. If the input signal remains high after exceeding the maximum high-pulse time-threshold (tHIGH_MAX_TH), the ESM detects a bad event and the high-pulse duration counter reinitializes. Each time the signal further exceeds the maximum threshold, the ESM detects a bad event. On the next falling edge on the input signal, the ESM starts the low-pulse time-duration monitoring. In addition, each ESM detects a bad-event in PWM mode if one of the events that follow occurs on the deglitched signal of the related input pin nERR_MCU or nERR_SoC: A high-pulse time-duration that is longer than the maximum high-pulse time-threshold (tHIGH_MAX_TH) that is configured in corresponding register bits ESM_MCU_HMAX[7:0] or ESM_SOC_HMAX[7:0].

Please note that when setting up the minimum and the maximum low-pulse or high-pulse time-thresholds need to be configured such that clock tolerances from the TPS6593-Q1 and from the processor are incorporated. #GUID-8AB05BFB-234E-4174-9368-666CD9A02C95/SLVSE826982, #GUID-8AB05BFB-234E-4174-9368-666CD9A02C95/SLVSE823780, #GUID-8AB05BFB-234E-4174-9368-666CD9A02C95/SLVSE827462, and #GUID-8AB05BFB-234E-4174-9368-666CD9A02C95/SLVSE825152 are a guideline on how to incorporate these clock-tolerances: ESM_x_HMIN[7:0] < 0.5 × (ESM_x_HMAX[7:0] + ESM_x_HMIN[7:0]) × 0.95 × (1 - MCU/SoC clock tolerance) ESM_x_HMAX[7:0] > 0.5 × (ESM_x_HMAX[7:0] + ESM_x_HMIN[7:0]) × 1.05 × (1 + MCU/SoC clock tolerance) ESM_x_LMIN[7:0] < 0.5 × (ESM_x_LMAX[7:0] + ESM_x_LMIN[7:0]) × 0.95 × (1 - MCU/SoC clock tolerance) ESM_x_LMAX[7:0] > 0.5 × (ESM_x_LMAX[7:0] + ESM_x_LMIN[7:0]) × 1.05 × (1 + MCU/SoC clock tolerance) , in which x stands for either MCU or SoC. ESM Error-Counter If an ESM detects a bad-event, it increments its related error-counter (bits ESM_MCU_ERR_CNT[4:0] or bits ESM_SOC_ERR_CNT[4:0]) by 2. If an ESM detects a good-event, it decrements its related error-counter (bits ESM_MCU_ERR_CNT[4:0] or bits ESM_SOC_ERR_CNT[4:0]) by 1. The device clears each ESM error counter when ESM_x_START=0. Furthermore, the device clears the error-counter ESM_SOC_ERR[4:0] when it resets the SoC. Each ESM error-counter has a related threshold (bits ESM_MCU_ERR_CNT_TH[3:0] or bits ESM_SOC_ERR_CNT_TH[3:0]) that the MCU can configure if the related ESM_x_START bit is 0. If the ESM error-counter value is above its configured threshold, the related ESM has detected a so-called ESM-error and starts the Error-Handling Procedure as described in . If the ESM error-counter reached a value equal or less its configured threshold before the elapse of the configured delay-1 or delay-2 intervals and the MCU software clears all ESM related interrupt bits, the ESM-error is no longer present and the ESM stops the Error-Handling Procedure as described in . If the ESM-error persists such that the configured delay-1 and delay-2 times elapse, the ESM sends a ESM_x_RST trigger to the PFSM and the device clears the ESM_x_START bit. After the PFSM completes the handling of the ESM_x_RST trigger, the device re-initializes the related ESM. ESM Start-Up in PWM Mode After the MCU has set the start bit of an ESM (bit ESM_MCU_START or bit ESM_SOC_START), there are two possible scenarios: The deglitched signal of the monitored input pin has a low level at the moment the MCU sets the start bit. In this scenario, the related ESM starts the following procedure: Start a timer with a time-length according the value configured in corresponding ESM_MCU_LMAX[7:0] or ESM_SOC_LMAX[7:0]. Wait for a first rising edge on its deglitched input signal. If the rising edge comes before the configured time-length elapses, the ESM skips the next step and starts to monitor the high-pulse duration time. Hereafter, the ESM detects good-events or bad-events as described in . shows an example this scenario as Case Number 1. If the configured time-length (configured in corresponding ESM_MCU_LMAX[7:0] or ESM_SOC_LMAX[7:0]) elapses, the ESM detects a bad-event and increments the related error-counter with +2. Hereafter, the ESM detects good-events or bad-events as described in . shows an example this scenario as Case Number 3. If the ESM error-counter value is above its configured threshold, the related ESM has detected a so-called ESM-error and starts the Error-Handling Procedure as described in . During this Error-Handling Procedure, the ESM continues to monitor its related input pin, and updates the error-counter accordingly when it detects good-events or bad-events, until the Error-Handling Procedure reaches the step in which the ESM sends an ESM_x_RST trigger to the PFSM, which, depending on the PFSM configuration, resets the MCU or SoC. shows a scenario in which the device resets the MCU or SoC as Case Number 4. If the ESM error-counter reaches a value equal or less its configured threshold before the elapse of the configured delay-1 or delay-2 time-intervals and the MCU software clears all ESM related interrupt bits, the ESM-error is no longer present and the ESM stops the Error-Handling Procedure as described in . The deglitched signal monitored input pin has a high level at the moment the MCU sets the start bit. In this scenario, the related ESM starts the following procedure: Start a timer with a time-length according the value configured in corresponding ESM_MCU_HMAX[7:0] or ESM_SOC_HMAX[7:0]. Wait for a first falling edge on its deglitched input signal. If the falling edge comes before the configured time-length elapses, the ESM skips the next step and starts to monitor the low-pulse duration time. Hereafter, the ESM detects good-events or bad-events as described in . shows an example this scenario as Case Number 2. If the configured time-length (configured in corresponding ESM_MCU_HMAX[7:0] or ESM_SOC_HMAX[7:0]) elapses, the ESM detects a bad-event and increments the related error-counter with +2. Hereafter, the ESM detects good-events or bad-events as described in . If the ESM error-counter value is above its configured threshold, the related ESM has detected a so-called ESM-error and starts the Error-Handling Procedure as described in .

At device start-up, the ESM_MCU and ESM_SoC can be enabled or deactivated through configuration bits ESM_MCU_EN and ESM_SOC_EN. The values for these configuration bits are stored in the NVM memory of the device. To start the enabled ESM, the MCU sets the start bits ESM_MCU_START or ESM_SOC_START for the corresponding ESM through software after the system is powered up and the initial software configuration is completed. If the MCU clears a start bit, the ESM stops monitoring its input pin. The MCU can set the ENABLE_DRV bit only when the MCU has either started or deactivated the ESM. When the corresponding ESM is started, the following configuration registers are write protected and can only be read: Configuration registers write-protected by the ESM_MCU_START register bit: ESM_MCU_DELAY1_REG ESM_MCU_DELAY2_REG ESM_MCU_MODE_CFG ESM_MCU_HMAX_REG ESM_MCU_HMIN_REG ESM_MCU_LMAX_REG ESM_MCU_LMIN_REG Configuration registers write-protected by the ESM_SOC_START register bit: ESM_SOC_DELAY1_REG ESM_SOC_DELAY2_REG ESM_SOC_MODE_CFG ESM_SOC_HMAX_REG ESM_SOC_HMIN_REG ESM_SOC_LMAX_REG ESM_SOC_LMIN_REG The ESM uses a deglitch-filter with deglitch-time tdegl_ESMx to monitor its related input pin. The MCU can configure the ESM in two different modes that are defined as follows: Level Mode the ESM detects an ESM-error when the input pin remains low for a time equal to or longer than the deglitch-time tdegl_ESMx. To select this mode for the ESM_MCU, the MCU must clear bit ESM_MCU_MODE. To select this mode for the ESM_SoC, the MCU must clear bit ESM_SOC_MODE. See for further detail. PWM Mode the ESM monitors a PWM signal at its input pin. The ESM detects a bad-event when the frequency or duty cycle of the PWM input signal deviates from the expected signal. The ESM detects a good-event when the frequency and duty cycle of the PWM signal match with the expected signal for one signal period. The ESM has an error-counter (ESM_MCU_ERR_CNT[4:0] or ESM_SOC_ERR_CNT[4:0]), which increments with +2 after each bad-event, and decrements with -1 after each good-event. The ESM detects an ESM-error when the error-counter value is more than its related threshold value. To select this mode for the ESM_MCU, the MCU must set bit ESM_MCU_MODE. To select this mode for the ESM_SoC, the MCU must set bit ESM_SOC_MODE. See for further details. The MCU can configure each ESM as long as its related start bit is cleared to 0 (bit ESM_MCU_START or ESM_SOC_START). As soon as the MCU sets a start bit, the device sets a write-protection on the configuration registers of the related ESM except the related start bits ESM_MCU_START and ESM_SOC_START. The TPS6593-Q1 device has two error signal monitor (ESMs): one ESM_MCU to monitor the MCU error output signal at the nERR_MCU input pin, and one ESM_SoC to monitor the SoC error output signal at the nERR_SoC input pin.

Below steps describe the procedure through which the ESM goes in case it detects an ESM-error: If the respective mask bit ESM_x_PIN_MASK=0, the device sets interrupt bit ESM_MCU_PIN_INT or ESM_SOC_PIN_INT, and pulls the nINT pin low. The ESM starts the delay-1 timer (configurable through related ESM_MCU_DELAY1[7:0] or ESM_SOC_DELAY1[7:0] bits). If the ESM-error is no longer present and MCU has cleared the related interrupt bit ESM_MCU_PIN_INT or ESM_SOC_PIN_INT before the delay-1 timer elapses, the device releases the nINTpin, the ESM resets the delay-1 and delay-2 timers and continues to monitor its input pin. If the ESM-error is still present, or if MCU has not cleared the related interrupt bit ESM_MCU_PIN_INT or ESM_SOC_PIN_INT, and the delay-1 timer elapses, then the ESM clears the ENABLE_DRV bit if bit ESM_MCU_ENDRV=1 or if bit ESM_SOC_ENDRV=1. If the delay-2 timer (configurable through related ESM_MCU_DELAY2[7:0] or ESM_SOC_DELAY2[7:0] bits) is set to 0, then the ESM skips steps 6 of this list, and performs step 7. If the delay-2 timer is not set to 0, then: ESM starts the delay-2 timer, If ESM_MCU_FAIL_MASK = 0, the device sets interrupt bit ESM_MCU_FAIL_INT and pulls the nINT pin low and starts the delay-2 timer. If ESM_SOC_FAIL_MASK = 0, the device sets interrupt bit ESM_SOC_FAIL_INT, pulls the nINT pin low and starts the delay-2 timer. If the ESM-error is no longer present and the MCU has cleared the related interrupt bits listed below before the delay-2 timer elapses, the device releases the nINTpin, the ESM resets the delay-1 and delay-2 timers and continues to monitor its input pin: ESM_MCU_PIN_INT (and ESM_MCU_FAIL_INT if set in step 6), or ESM_SOC_PIN_INT (and ESM_SOC_FAIL_INT if set in step 6) If the ESM-error is still present, or if MCU has not cleared the related interrupt bits ESM_MCU_PIN_INT and ESM_MCU_FAIL_INT , or ESM_SOC_PIN_INT and ESM_SOC_FAIL_INT, and the delay-2 timer elapses, then : For ESM_MCU, the device: clears the ESM_MCU_START BIT sets interrupt bits ESM_MCU_FAIL_INT and ESM_MCU_RST_INT, which the device handles as an ESM_MCU_RST trigger for FSM, described in Summary of Interrupt Signals After this trigger handling completes, the device re-initializes the ESM_MCU For ESM_SoC, the device: clears the ESM_SOC_START bit sets interrupt bits ESM_SOC_FAIL_INT and ESM_SOC_RST_INT, which the device handles as an ESM_SOC_RST trigger for FSM, described in Summary of Interrupt Signals After this trigger handling completes, the device re-initializes the ESM_SoC ESM_MCU_DELAY1[7:0] and ESM_SOC_DELAY1[7:0] set the delay-1 time-interval (tDELAY-1) for the related ESM_MCU or ESM_SoC.

Level Mode In Level Mode, after MCU has set the start bit (bit ESM_MCU_START or bit ESM_SOC_START), the ESM monitors its nERR_MCU or nERR_SoC input pin. Each ESM detects an ESM-error when the voltage level on its input pin remains low for a time equal or longer than the deglitch-time tdegl_ESMx. When an ESM_x detects an ESM-error, it starts the ESM Error-Handling procedure as described in . The Error-Handling Procedure is stopped if, before elapse of the delay-1 or delay-2 interval, the voltage level on the input pin remains high for a time equal or longer than the deglitch-time tdegl_ESMx and the MCU clears all corresponding interrupt bits. If the ESM-error persists such that the configured delay-1 and delay-2 times elapse, the ESM sends a ESM_x_RST trigger to the PFSM and the device clear the ESM_x_START bit. After the PFSM completes the handling of the ESM_x_RST trigger, the device re-initializes the ESM. For a complete overview on how the ESM works in Level Mode, please refer to the flow-chart in .

If the input signal remains low after exceeding the maximum low-pulse time-threshold (tLOW_MAX_TH), the ESM detects a bad event and the low-pulse duration counter reinitializes. Each time the signal further exceeds the maximum threshold, the ESM detects a bad event.

ESM Error-Counter If an ESM detects a bad-event, it increments its related error-counter (bits ESM_MCU_ERR_CNT[4:0] or bits ESM_SOC_ERR_CNT[4:0]) by 2. If an ESM detects a good-event, it decrements its related error-counter (bits ESM_MCU_ERR_CNT[4:0] or bits ESM_SOC_ERR_CNT[4:0]) by 1. The device clears each ESM error counter when ESM_x_START=0. Furthermore, the device clears the error-counter ESM_SOC_ERR[4:0] when it resets the SoC. Each ESM error-counter has a related threshold (bits ESM_MCU_ERR_CNT_TH[3:0] or bits ESM_SOC_ERR_CNT_TH[3:0]) that the MCU can configure if the related ESM_x_START bit is 0. If the ESM error-counter value is above its configured threshold, the related ESM has detected a so-called ESM-error and starts the Error-Handling Procedure as described in . If the ESM error-counter reached a value equal or less its configured threshold before the elapse of the configured delay-1 or delay-2 intervals and the MCU software clears all ESM related interrupt bits, the ESM-error is no longer present and the ESM stops the Error-Handling Procedure as described in . If the ESM-error persists such that the configured delay-1 and delay-2 times elapse, the ESM sends a ESM_x_RST trigger to the PFSM and the device clears the ESM_x_START bit. After the PFSM completes the handling of the ESM_x_RST trigger, the device re-initializes the related ESM. ESM Start-Up in PWM Mode After the MCU has set the start bit of an ESM (bit ESM_MCU_START or bit ESM_SOC_START), there are two possible scenarios: The deglitched signal of the monitored input pin has a low level at the moment the MCU sets the start bit. In this scenario, the related ESM starts the following procedure: Start a timer with a time-length according the value configured in corresponding ESM_MCU_LMAX[7:0] or ESM_SOC_LMAX[7:0]. Wait for a first rising edge on its deglitched input signal. If the rising edge comes before the configured time-length elapses, the ESM skips the next step and starts to monitor the high-pulse duration time. Hereafter, the ESM detects good-events or bad-events as described in . shows an example this scenario as Case Number 1. If the configured time-length (configured in corresponding ESM_MCU_LMAX[7:0] or ESM_SOC_LMAX[7:0]) elapses, the ESM detects a bad-event and increments the related error-counter with +2. Hereafter, the ESM detects good-events or bad-events as described in . shows an example this scenario as Case Number 3. If the ESM error-counter value is above its configured threshold, the related ESM has detected a so-called ESM-error and starts the Error-Handling Procedure as described in . During this Error-Handling Procedure, the ESM continues to monitor its related input pin, and updates the error-counter accordingly when it detects good-events or bad-events, until the Error-Handling Procedure reaches the step in which the ESM sends an ESM_x_RST trigger to the PFSM, which, depending on the PFSM configuration, resets the MCU or SoC. shows a scenario in which the device resets the MCU or SoC as Case Number 4. If the ESM error-counter reaches a value equal or less its configured threshold before the elapse of the configured delay-1 or delay-2 time-intervals and the MCU software clears all ESM related interrupt bits, the ESM-error is no longer present and the ESM stops the Error-Handling Procedure as described in . The deglitched signal monitored input pin has a high level at the moment the MCU sets the start bit. In this scenario, the related ESM starts the following procedure: Start a timer with a time-length according the value configured in corresponding ESM_MCU_HMAX[7:0] or ESM_SOC_HMAX[7:0]. Wait for a first falling edge on its deglitched input signal. If the falling edge comes before the configured time-length elapses, the ESM skips the next step and starts to monitor the low-pulse duration time. Hereafter, the ESM detects good-events or bad-events as described in . shows an example this scenario as Case Number 2. If the configured time-length (configured in corresponding ESM_MCU_HMAX[7:0] or ESM_SOC_HMAX[7:0]) elapses, the ESM detects a bad-event and increments the related error-counter with +2. Hereafter, the ESM detects good-events or bad-events as described in .

Below steps describe the procedure through which the ESM goes in case it detects an ESM-error: If the respective mask bit ESM_x_PIN_MASK=0, the device sets interrupt bit ESM_MCU_PIN_INT or ESM_SOC_PIN_INT, and pulls the nINT pin low. The ESM starts the delay-1 timer (configurable through related ESM_MCU_DELAY1[7:0] or ESM_SOC_DELAY1[7:0] bits).

If the ESM-error is still present, or if MCU has not cleared the related interrupt bit ESM_MCU_PIN_INT or ESM_SOC_PIN_INT, and the delay-1 timer elapses, then the ESM clears the ENABLE_DRV bit if bit ESM_MCU_ENDRV=1 or if bit ESM_SOC_ENDRV=1.

If the input signal remains low after exceeding the maximum low-pulse time-threshold (tLOW_MAX_TH), the ESM detects a bad event and the low-pulse duration counter reinitializes. Each time the signal further exceeds the maximum threshold, the ESM detects a bad event.

If the input signal remains high after exceeding the maximum high-pulse time-threshold (tHIGH_MAX_TH), the ESM detects a bad event and the high-pulse duration counter reinitializes. Each time the signal further exceeds the maximum threshold, the ESM detects a bad event. On the next falling edge on the input signal, the ESM starts the low-pulse time-duration monitoring.

ESM Error-Counter If an ESM detects a bad-event, it increments its related error-counter (bits ESM_MCU_ERR_CNT[4:0] or bits ESM_SOC_ERR_CNT[4:0]) by 2. If an ESM detects a good-event, it decrements its related error-counter (bits ESM_MCU_ERR_CNT[4:0] or bits ESM_SOC_ERR_CNT[4:0]) by 1. The device clears each ESM error counter when ESM_x_START=0. Furthermore, the device clears the error-counter ESM_SOC_ERR[4:0] when it resets the SoC. Each ESM error-counter has a related threshold (bits ESM_MCU_ERR_CNT_TH[3:0] or bits ESM_SOC_ERR_CNT_TH[3:0]) that the MCU can configure if the related ESM_x_START bit is 0. If the ESM error-counter value is above its configured threshold, the related ESM has detected a so-called ESM-error and starts the Error-Handling Procedure as described in . If the ESM error-counter reached a value equal or less its configured threshold before the elapse of the configured delay-1 or delay-2 intervals and the MCU software clears all ESM related interrupt bits, the ESM-error is no longer present and the ESM stops the Error-Handling Procedure as described in . If the ESM-error persists such that the configured delay-1 and delay-2 times elapse, the ESM sends a ESM_x_RST trigger to the PFSM and the device clears the ESM_x_START bit. After the PFSM completes the handling of the ESM_x_RST trigger, the device re-initializes the related ESM. ESM Start-Up in PWM Mode After the MCU has set the start bit of an ESM (bit ESM_MCU_START or bit ESM_SOC_START), there are two possible scenarios: The deglitched signal of the monitored input pin has a low level at the moment the MCU sets the start bit. In this scenario, the related ESM starts the following procedure: Start a timer with a time-length according the value configured in corresponding ESM_MCU_LMAX[7:0] or ESM_SOC_LMAX[7:0]. Wait for a first rising edge on its deglitched input signal. If the rising edge comes before the configured time-length elapses, the ESM skips the next step and starts to monitor the high-pulse duration time. Hereafter, the ESM detects good-events or bad-events as described in . shows an example this scenario as Case Number 1. If the configured time-length (configured in corresponding ESM_MCU_LMAX[7:0] or ESM_SOC_LMAX[7:0]) elapses, the ESM detects a bad-event and increments the related error-counter with +2. Hereafter, the ESM detects good-events or bad-events as described in . shows an example this scenario as Case Number 3. If the ESM error-counter value is above its configured threshold, the related ESM has detected a so-called ESM-error and starts the Error-Handling Procedure as described in . During this Error-Handling Procedure, the ESM continues to monitor its related input pin, and updates the error-counter accordingly when it detects good-events or bad-events, until the Error-Handling Procedure reaches the step in which the ESM sends an ESM_x_RST trigger to the PFSM, which, depending on the PFSM configuration, resets the MCU or SoC. shows a scenario in which the device resets the MCU or SoC as Case Number 4. If the ESM error-counter reaches a value equal or less its configured threshold before the elapse of the configured delay-1 or delay-2 time-intervals and the MCU software clears all ESM related interrupt bits, the ESM-error is no longer present and the ESM stops the Error-Handling Procedure as described in . The deglitched signal monitored input pin has a high level at the moment the MCU sets the start bit. In this scenario, the related ESM starts the following procedure: Start a timer with a time-length according the value configured in corresponding ESM_MCU_HMAX[7:0] or ESM_SOC_HMAX[7:0]. Wait for a first falling edge on its deglitched input signal. If the falling edge comes before the configured time-length elapses, the ESM skips the next step and starts to monitor the low-pulse duration time. Hereafter, the ESM detects good-events or bad-events as described in . shows an example this scenario as Case Number 2. If the configured time-length (configured in corresponding ESM_MCU_HMAX[7:0] or ESM_SOC_HMAX[7:0]) elapses, the ESM detects a bad-event and increments the related error-counter with +2.

The device supports NVM-configurable mission states with configurable input triggers for transitions between states. Any resources, including the 5 BUCK regulators, 4 LDO regulators, and all of the digital IO pins including the 11 GPIO pins on the device can be controlled during power sequencing. When a resource is not controlled or configured through a power sequence, the resource is left in the default state as pre-configured by the NVM. Each resource can be pre-configured through the NVM configuration, or re-configured through register bits. Therefore, the user can statically control the resource through the control interfaces (I2C or SPI), or the FSM can automatically control the resource during state sequences. The FSM is powered by an internal LDO that is automatically enabled when VCCA supply is available to the device. Ensuring that the VCCA supply is the first supply available to the device is important to ensure proper operation of all the power resources as well as the control interface and device IOs. There are three parts of the FSM that control the operational modes of the TPS6593-Q1 device: Fixed Device Power Finite State Machine (FFSM) Pre-configurable Finite State Machine (PFSM) for Mission States (ACTIVE, MCU_ONLY, S2R, DEEP_SLEEP) Error Handling Operations The PFSM provides configurable rail and voltage monitoring sequencing utilizing instructions in configuration memory. This flexibility enables customers to alter power-up sequences on a platform basis. The FFSM handles the majority of fixed functionality that is internally mandated and common to all platforms. Fixed Device Power FSM The Fixed Device Power portion of the FSM engine manages the power up of the device before the power rails are fully enabled and ready to power external loadings, and the power down of the device when in the event of insufficient power supply or device or system error conditions. While the device is in one of the Hardware Device Powers states, the ENABLE_DRV bit remains low. The definitions and transition triggers of the Device Power States are fixed and cannot be reconfigured. Following are the definitions of the Device Power states: NO SUPPLY The device is not powered by a valid energy source on the system power rail. The device is completely powered off. BACKUP (RTC backup battery) The device is not powered by a valid supply on the system power rail (VCCA < VCCA_UVLO); a backup power source, however, is present and is within the operating range of the LDOVRTC. The RTC clock counter remains active in this state if it has been previously activated by appropriate register enable bit. The calendar function of the RTC block is activated, but not accessible in this state. Customer has the option to enable the shelf mode by disconnecting the VCCA supply completely, even while the backup battery is connected to the VBACKUP pin. The shelf mode forces the device to skip the BACKUP state and enters the NO SUPPLY state under VCCA_UVLO condition to reduce current draining from the backup battery. LP_STANDBY The device can enter this state from a mission state after receiving a valid OFF request or an I2C trigger, and the LP_STANDBY_SEL= 1. When the device is in this state, the RTC clock counter and the RTC Alarm or Timer Wake-up functions are active if they have been previously activated by appropriate register enable bit. Low Power Wake-up input monitor in the LDOVRTC domain (LP_WKUP secondary function through GPIO3 or GPIO4) and the on request monitors are also enabled in this state. When a logic level transition from high-to-low or low-to-high with a minimum pulse length of tLP_WKUP is detected on the assigned LP_WKUP pin, or if the device detects a valid on-request or a wake-up signal from the RTC block, the device proceeds to power up the device and reach the default mission state. More details regarding the LP_WAKE function can be found in . INIT The device is powered by a valid supply on the system power rail (VCCA ≥ VCCA_UV). If the device was previously in LP_STANDBY state, it has received an external wake-up signal at the LP_WKUP1/2 pins, the RTC alarm or timer wake-up signal, or an On Request from the nPWRON/ENABLE pin. Device digital and monitor circuits are powered up. The PMIC reads its internal NVM memory in this state and configures default values to registers, IO configuration and FSM accordingly. BOOT BIST The device is running the built-in self-test routine that includesThe ABIST on the voltage monitor circuits for the BUCK regulators, the LDO regulators is performed after the start-up of these regulators. The ABIST on the VMON1 and VMON2 is performed after these voltage monitors are enabled. See Voltage Monitors. An option is available to shorten the device power up time from the NO_SUPPLY state by setting the NVM bit FAST_BOOT_BIST = '1' to skip the LBIST. Software can also set the FAST_BIST = '1' to skip LBIST after the device wakes up from the LP STANDBY state. When the device arrives at this state from the SAFE_RECOVERY state, LBIST is automatically skipped if it has not previously failed. If LBIST failed, but passed after multiple re-tries before exceeding the recovery counter limit, the device powers up normally. The following NVM bits are pre-configured options to enable or disable parts of the CRC tests if further sequence time reduction is required (please refer to the user's guide of the orderable part number): REG_CRC_EN = '0': disables the register map and SRAM CRC check Note: the BIST tests are executed as parallel processes, and the longest process determines the total BIST duration the ABIST on the voltage monitor circuits of the BUCKx regulator, LDOn regulators, VMON1 and VMON2 is performed individually after these voltage monitors are enabled. See Voltage Monitors) RUNTIME BIST A request was received from the MCU to exercise a run-time built-in self-test (RUNTIME_BIST) on the device. No rails are modified and all external signals, including all I2C or SPI interface communications, are ignored during the RUNTIME_ BIST. During the RUNTIME_BIST, the device performs the same self-test routines as listed for the BOOT_BIST state. Furthermore, during RUNTIME_BIST the device performs the ABIST routine on all enabled voltage monitor circuits. If the device passed BIST, it resumes the previous operation. If the device failed BIST, it shuts down all of the regulator outputs and proceed to the SAFE RECOVERY state. In order to avoid a register CRC error, all register writes must be avoided after the request for the BIST operation until the device pulls the nINT pin low to indicate the completion of BIST. The results of the RUNTIME_BIST are indicated by the BIST_PASS_INT or the BIST_FAIL_INT interrupt bits.After completion of the RUNTIME_BIST, the LDOx_UV detections are masked for a time-interval equal to the configured LDOx ramp-up time (25 mV/μs or 3 mV/μs according configuration bit LDOx_SLOW_RAMP). The actual LDOx output voltages are not affected by this masking of the LDOx_UV detections. SAFE RECOVERY The device meets the qualified error condition for immediate or ordered shutdown request. If the error is recovered within the recovery time interval or meets the restart condition, the device increments the recovery counter, and returns to INIT state if the recovery counter value does not exceed the threshold value. Until a supply power cycle occurs, the device stays in the SAFE RECOVERY state if one of the following conditions occur: the recovery counter exceeds the threshold value the die temperature cannot be reduced to less than TWARN level VCCA stays above OVP threshold When multiple system conditions occur simultaneously that demand power state arbitration, the device goes to the higher priority state according to the following priority order: NO SUPPLY BACKUP SAFE_RECOVERY LP_STANDBY MISSION STATES shows the power transition states of the FSM engine. State Diagram for Device Power States Register Resets and NVM Read at INIT State Several registers inside the TPS6593-Q1 have pre-configured default values that are stored in the NVM of the TPS6593-Q1. These registers are referred to as NVM pre-configured registers. When the device transitions from the LP_STANDBY or the SAFE_RECOVERY to the INIT state, based on FIRST_STARTUP_DONE bit, the registers are reset and the NVM is read. When the FIRST_STARTUP_DONE is '0', registers which are not in the RTC domain are reset, and all of the NVM pre-configured registers including the ones in the RTC domain, are loaded from the NVM. When the FIRST_STARTUP_DONE bit is set to '1', typically after the initial power up from a supply power cycle, the registers in the RTC domain are not reset, and the NVM pre-configured registers in the RTC domain are not re-loaded from the NVM. Setting the FIRST_STARTUP_DONE bit prevents the control and status bits stored in the RTC domain registers from being over written. Register resets and NVM read at INIT state FIRST _STARTUP_DONE NVM pre-configured registers in RTC Domain Registers without NVM pre-configuration in RTC Domain Other NVM pre-configured registers Registers without NVM pre-configuration 0 Defaults read from NVM No changes Reset and defaults read from NVM Reset 1 No changes No changes Reset and defaults read from NVM Reset Below are the NVM pre-configured register bits in the RTC domain: GPIO3_CONF and GPIO4_CONF registers, except the GPIOn_DEGLITCH_EN bits GPIO3_RISE_MASK, GPIO3_FALL_MASK, GPIO4_RISE_MASK, and GPIO4_FALL_MASK bits NPWRON_CONF register except ENALBE_DEGLITCH_EN and NRSTOUT_OD bits FSD_MASK, ENABLE_MASK, NPWRON, START_MASK, and NPWRON_LONG_MASK bits STARTUP_DEST, FAST_BIST, LP_STANDBY_SEL, XTAL_SEL, and XTAL_EN bits PFSM_DELAYn, and RTC_SPARE_n bits Below are the register bits without NVM pre-configuration in the RTC domain: FIRST_STARTUP_DONE bit SCRATCH_PAD_n bits All of RTC control and configuration registers Pre-Configurable Mission States When the device arrives at a mission state, all rail sequencing is controlled by the pre-configurable FSM engine (PFSM) through the configuration memory. The configuration memory allows configurations of the triggers and the operation states that together form the configurable sub state machine within the scope of mission states. This sub state machine can be used to control and sequence the different voltage outputs as well as any GPIO outputs that can be used as enable for external rails. When the device is in a mission state, it has the capacity to supply the processor and other platform modules depending on the power rail configuration. The definitions and transition triggers of the mission states are configurable through the NVM configuration. Unlike the user registers, the PFSM definition stored in the NVM cannot be modified during normal operation. When the PMIC determines that a transition to another operation state is necessary, it reads the configuration memory to determine what sequencing is needed for the state transition. Furthermore, the PFSM has four storage registers, further referred to as PFSM storage registers (R0-3). shows how the trigger signals for each state transition can come from a variety of interface or GPIO inputs, or potential error sources. shows how the device processes all of the possible error sources inside the PFSM engine, a hierarchical mask system is applied to filter out the common errors that can be handled by interrupt only, and categorize the other error sources as Severe Global Error, Moderate Global Error, and so forth. The filtered and categorized triggers are sent into the PFSM engine, that then determines the entry and exit condition for each configured mission state. Error Source Hierarchical Mask System shows an example of how the PFSM engine utilizes instructions to execute the configured device state and sequence transitions of the mission state-machine. provides the instruction set and usage description of each instruction in the following sections. describes how the instructions are stored in the NVM memory.

REG_WRITE_VOUT_IMM Command Description: Write the target voltage of a specified regulator after a specified delay. This command is a spin-off of the REG_WRITE_IMM command with the intention to save instruction bits.

Delay value is be rounded to the nearest achievable delay time based on the current step size. Current step size is based on the default NVM setting or a SET_DELAY value from a previous command in the same sequence. Assembler reports an error if the step size is too large or too small to meet the delay. Delay Mode must be one of the below options: MATCH_EN = 0 (Delay if VCTRL enable bit mismatches) MATCH_ALL = 1 (Delay if any VCTRL bits mismatch) ALWAYS = 2 (Delay always) Examples: REG_WRITE_VCTRL_IMM BUCK3 0x00 0xE0 100 µs — Sets BUCK3 to OFF (VCTRL bits = 0b00000) after 100 µs REG_WRITE_VCTRL_IMM REGULATOR=LDO1 VCTRL=0x09 MASK=0x36 DELAY=10 ms — Set LDO1_VMON and LDO1_EN to '1' after 10 ms REG_WRITE_MASK_SREG Command Description: Write the data from a PFSM storage register, except the masked bits, to the specified register address Assembly command: REG_WRITE_MASK_SREG [REG=]<PFSM Storage Register> [ADDR=]<Address> [MASK=]<Mask> 'REG=', 'ADDR=', and 'MASK=' are options. When included, the parameters can be in any order. PFSM Storage Register can be R0, R1, R2, or R3. Address and Mask can be in any literal integer format (decimal, hex, and so forth). Examples: REG_WRITE_MASK_SREG R2 0x22 0x00 — Write the content of PFSM storage register R2 to address 0x22 REG_WRITE_MASK_SREG REG=R0 ADDR=0x054 MASK=0xF0 — Write the lower 4 bits of PFSM storage register R0 to address 0x54 SREG_READ_REG Command Description: Write PFSM storage register (R0-3) with data from a specified address Assembly command: SREG_READ_REG [REG=]<PFSM Storage Register> [ADDR=]<Address> 'REG=' and 'ADDR=' are options.

Execution is paused until the specified type of the condition is met or timed out Assembly command: WAIT [COND=]<Condition> [TYPE=]<Type> [TIMEOUT=]<Timeout> [DEST=]<Destination> Alternative assembly command: JUMP [DEST=]<Destination> 'COND=', 'TYPE=', 'TIMEOUT=', and 'DEST=' are options. When included, the parameters can be in any order. Condition are listed in #GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/SLVSEA74920. Examples: GPIO1, BUCK1_PG, I2C_1 Type = LOW, HIGH, RISE, or FALL Timeout = timeout value in ns, µs, ms, or s. If no unit is entered, this field must be an integer value between 0-63. Timeout value is be rounded to the nearest achievable time based on the current step size. Current step size is based on the default NVM setting or a SET_DELAY value from a previous command in the same sequence. Assembler reports an error if the step size is too large or too small to meet the delay. Destination = Label to jump to if when timeout occurs. Destination must be after the WAIT statement in memory. Memory space can be either '0' or '1'. '0' indicates the destination address is in the PFSM memory space. '1' indicates the destination address is external and represents a FSM state ID. When using the jump command, the PFSM performs an unconditional jump. The command is be compiled as "WAIT COND=63 TYPE=LOW TIMEOUT=0 DEST=<Destination>". Condition 63 is a hardcoded 1, so the condition is never satisfied and hence always times out. Therefore this command always jumps to the destination. Examples: WAIT GPIO4 RISE 1 s <Destination> 0 — Wait to execute the command at the specified SRAM address when a rise edge is detected at GPIO4, or after 1 second WAIT COND=BUCK1_PG TYPE=HIGH TIMEOUT=500 µs DEST=<mcu2act_seq> — Wait to execute the commands at <mcu2act_seq> address as soon as BUCK1 output is within power-good range, or after 500 µs WAIT Command Conditions COND_SEL Condition Name COND_SEL Condition Name COND_SEL Condition Name COND_SEL Condition Name 0 GPIO1#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 16 LDO1_PG 32 I2C_0#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 48 LP_STANDBY_SEL 1 GPIO2#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 17 LDO2_PG 33 I2C_1#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 49 N/A 2 GPIO3#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 18 LDO3_PG 34 I2C_2#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 50 N/A 3 GPIO4#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 19 LDO4_PG 35 I2C_3#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 51 N/A 4 GPIO5#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 20 PGOOD 36 I2C_4#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 52 N/A 5 GPIO6#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 21 TWARN_EVENT 37 I2C_5#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 53 N/A 6 GPIO7 22 INTERRUPT_PIN 38 I2C_6#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 54 N/A 7 GPIO8 23 N/A 39 I2C_7#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 55 N/A 8 GPIO9 24 N/A 40 SREG0_0#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 56 N/A 9 GPIO10 25 N/A 41 SREG0_1#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 57 N/A 10 GPIO11 26 N/A 42 SREG0_2#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 58 N/A 11 BUCK1_PG 27 N/A 43 SREG0_3#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 59 N/A 12 BUCK2_PG 28 N/A 44 SREG0_4#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 60 N/A 13 BUCK3_PG 29 N/A 45 SREG0_5#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 61 N/A 14 BUCK4_PG 30 N/A 46 SREG0_6#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 62 0 15 BUCK5_PG(use for EXT_VMON PowerGood) 31 N/A 47 SREG0_7#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 63 1 Conditions GPIO1..GPIO6 are only processed if the associated GPIOx pins are configured as GPIO Conditions I2C0..7 refer to register bits TRIGGER_I2C_0..7, and are located in register FSM_I2C_TRIGGER Conditions SREG0_0...7 refer to bits 9...7 in PFSM storage register R0 DELAY_IMM Command Description: Delay the execution by a specified time Assembly command: DELAY_IMM <Delay> Delay = delay time in ns, µs, ms, or s. If no unit is entered, this field must be an integer value between 0-63. Delay value is be rounded to the nearest achievable time based on the current step size. Current step size is based on the default NVM setting or a SET_DELAY value from a previous command. Assembler reports an error if the step size is too large or too small to meet the delay. Examples: DELAY_IMM 100 µs — Delay execution by 100 µs DELAY_IMM 10 ms — Delay execution by 10 ms DELAY_IMM 8 — Delay execution by 8 ticks of the current PFSM time step DELAY_SREG Command Description: Delay the execution by a time value stored in the specified scratch register. The delay is calculated based on the curernt step size based on the value stored in PFSM_DELAY_STEP, or a SET_DELAY value from a previous command. Assembly command: DELAY_SREG <PFSM Storage Register> PFSM Storage Register can be R0, R1, R2, or R3. Examples: DELAY_SREG R0 — Delay execution by the time value stored in PFSM storage register R0 TRIG_SET Command Description: Set a trigger destination address for a given input signal or condition. These commands must be defined at the beginning of PFSM configuration memory. Assembly command: TRIG_SET [DEST=]<Destination> [ID=]<Trig_ID> [SEL=]<Trig_sel> [TYPE=]<Trig_type> [IMM=]<IMM> [EXT=]<Memory space> 'DEST=', 'ID=', 'SEL='. 'TYPE=', 'IMM=', and 'EXT=' are options. When included, the parameters can be in any order. Destination is the label where this trigger starts executing. Trig_ID is the ID of the hardware trigger module to be configured (value range 0-27). They must be defined in numeric order based on the priority of the trigger. Trig_Sel is the 'Trigger Name' from the . This 'Trigger Name' is the trigger signal to be associated with the specified TRIG_ID. Trig_type = LOW, HIGH, RISE, or FALL. IMM can be either '0' or '1'. = '0' if the trigger is not activated until the END command of a given task; '1' if the trigger is activated immediately and can abort a sequence. REENTRANT can be either '0' or '1'. '1' permits a trigger to return to the current state, that allows a self-branching trigger to execute the current sequence again. Memory space can be either '0' or '1'. '0' indicates the destination address is in the PFSM memory space. '1' indicates the destination address is external and represents a FSM state ID. Examples: TRIG_SET seq1 20 GPIO_1 LOW 0 0 — Set trigger 20 to be GPIO_1=Low, not immediate. When triggered, start executing at ‘seq1’ label. TRIG_SET DEST=seq2 ID=15 SEL=WD_ERROR TYPE=RISE IMM=0 EXT=0 — Set trigger 15 to be rising WD_ERROR trigger, not immediate. When triggered, start executing at ‘seq2’ label. TRIG_MASK Command Description: Sets a trigger mask that determines which triggers are active. Setting a ‘0’ enables the trigger, setting a ‘1’ disables (masks) the trigger. Assembly command: TRIG_MASK <Mask value> Mask Value = 28-bit mask in any literal integer format (decimal, hex, and so forth). Examples: TRIG_MASK 0x5FF82F0 — Set the trigger mask to 0x5FF82F0 END Command #GUID-829AAD39-C301-4ED7-A234-62018DE2CD53/X6385 shows the format of the END commands. END Command Format Bit[3:0] CMD 4 bits Description: Marks the final instruction in a sequential task Fields: CMD: Command opcode (0xC) Assembly command: END Configuration Memory Organization and Sequence Execution The configuration memory is loaded from NVM into an SRAM. shows an example configuration memory with only two configured sequences. Configuration Memory Script Example As soon as the PMIC state reaches the mission states, it starts reading from the configuration memory until it hits the first END command. Setting up the triggers (1-28) must be the first section of the configuration memory, as well as the first set of trigger configurations. The trigger configurations are read and mapped to an internal lookup table that contains the starting address associated with each trigger in the configuration memory. If the trigger destination is an FFSM state then the address contains the fixed state value. After the trigger configurations are read and mapped into the SRAM, these triggers control the execution flow of the state transitions. The signal source of each trigger is listed under . When a trigger or multiple triggers are activated, the PFSM execution engine looks up the starting address associated with the highest priority unmasked trigger, and starts executing commands until it hits an END command. The last commands before END statement is generally the TRIG_MASK command, which directs the PFSM to a new set of unmasked trigger configurations, and the trigger with the highest priority in the new set is serviced next. Trigger priority is determined by the Trigger ID associated with each trigger. The priority of the trigger decreases as the associated trigger ID increases. As a result, the critical error triggers are usually located at the lowest trigger IDs. The TRIG_SET commands specify if a trigger is immediate or non-immediate. Immediate triggers are serviced immediately, which involves branching from the current sequence of commands to reach a new target destination. The non-immediate triggers are accumulated and serviced in the order of priority through the execution of each given sequence until the END command in reached. Therefore, the trigger ID assignment for each trigger can be arranged to produce the desired PFSM behavior. The TRIG_MASK command determines which triggers are active at the end of each sequence, and is usually placed just before the END instruction. The TRIG_MASK takes a 28-bit input to allow any combination of triggers to be enabled with a single command. Through the definition of the active triggers after each sequence execution the TRIG_MASK command can be conceptualized as establishing a power state. The above sequence of waiting for triggers and executing the sequence associated with an activated trigger is the normal operating condition of the PFSM execution engine when the PMIC is in the MISSION state. The fixed device power FSM takes over control from the execution engine each time an event occurs that requires a transition from the MISSION state of the PMIC to a fixed device state. PFSM Trigger Selections Trigger Name Trigger Source IMMEDIATE_SHUTDOWN An error event causes one of the triggers defined in the FSM_TRIG_SEL_1/2 register to activate, and the intended action for the activated trigger is to immediate shutdown the device.

The is used as an example state machine that is defined through the configuration memory using the configuration FSM instructions. Example of a Mission State-Machine Each power state (light blue bubbles in ) defines the ON or OFF state and the sequencing timing of the external regulators and GPIO outputs. This example defines four power states: STANDBY, ACTIVE, MCU ONLY, and DEEP_SLEEP/S2R three power states: STANDBY, ACTIVE and RETENTION states. The priority order of these states is as follows: ACTIVE MCU ONLY DEEP SLEEP/S2R STANDBY The transitions between each power state is determined by the trigger signals source pre-selected from . These triggers are then placed in the order of priority through the trigger ID assignment of each trigger source. The critical error triggers are placed first, some specified as immediate triggers that can interrupt an on-going sequence. The non-error triggers, which are used to enable state transitions during normal device operation, are then placed according to the priority order of the state the device is transitioning to. list the trigger signal sources, in the order of priority, used to define the power states and transitions of the example mission state machine shown in . This table also helps to determine which triggers must be masked by the TRIG_MASK command upon arriving a pre-defined power state to produce the desired PFSM behavior.

When an error occurs, which requires the device to enter directly to the SAFE RECOVERY state, the mask for this trigger must be removed while all other non-immediate triggers are masked. The device exits the mission states and the FFSM state machine takes over control of the device power states once this trigger is executed. Pre-Configured Hardware Transitions There are some pre-defined trigger sources, such as on-requests and off-requests, that are constructed with the combination of hardware input signals and register bits settings. This section provides more detail to these pre-defined trigger sources and shows how they can be utilized in the PFSM configuration to initiate state to state transitions. ON Requests ON requests are used to switch on the device, which then transitions the device from the STANDBY or the LP_STANDBY to the state specified by STARTUP_DEST[1:0]. After the device arrives at the corresponding STARTUP_DEST[1:0] operation state, the MCU must setup the SLEEP1 and NSLEEP2 signals accordingly before clearing the STARTUP_INT interrupt. Once the interrupt is cleared, the device stays or moves to the next state corresponding to the NSLEEP signals state assignment as specified in . #GUID-CF09F512-F01B-4591-9EAD-EE716C2976A4/SLVSEA76972 lists the available ON requests. ON Requests EVENT MASKABLE COMMENT DEBOUNCE nPWRON (pin) Yes Edge sensitive 50 ms ENABLE (pin) Yes Level sensitive 8 µs First Supply Detection (FSD) Yes VCCA > VCCA_UV and FSD unmasked N/A RTC ALARM Interrupt Yes N/A RTC TIMER Interrupt Yes N/A WKUP1 or WKUP2 Detection Yes Edge sensitive 8 µs LP_WKUP1 or LP_WKUP2 Detection Yes Edge sensitive N/A Recovery from Immediate and Orderly Shutdown No Recover from system errors which caused immediate or orderly shutdown of the device N/A If one of the events listed in #GUID-CF09F512-F01B-4591-9EAD-EE716C2976A4/SLVSEA76972 occurs, then the event powers on the device unless one of the gating conditions listed in #GUID-CF09F512-F01B-4591-9EAD-EE716C2976A4/SLVSEA71946 is present. ON Requests Gating Conditions EVENT MASKABLE COMMENT VCCA_OVP (event) No VCCA > VCCA_OVP Device stays in SAFE RECOVERY until VCCA < VCCA_OVP VCCA_UVLO (event) No VCCA < VCCA_UVLO VINT_OVP (event) No LDOVINT > 1.98 V VINT_UVLO (event) No LDOVINT < 1.62 V TSD (event) No Device stays in SAFE RECOVERY until temperature decreases below TWARN level The NPWRON_SEL NVM register bit determines whether the nPWRON/ENABLE pin is treated as a power on press button or a level sensitive enable switch. When this pin is configured as the nPWRON button, a short button press detection is latched internally as a device enable signal until the NPWRON_START_INT is cleared, or a long press key event is detected. The short button press detection occurs when an falling edge is detected at the nPWRON pin. When the NPWRON_START_MASK bit is set to '1', the device does no longer react to the changing state of the pin as the nPWRON press button. The nPWRON/ENABLE pin is a level sensitive pin when it is configured as an ENABLE pin, and an assertion enables the device until the pin is released. When the ENABLE_MASK bit is set to '1', the device does no longer react to the changing state of the pin as the ENABLE switch. OFF Requests An OFF request is used to orderly switch off the device. OFF requests initiate transition from any other mission state to the STANDBY state or the LP_STANDBY state depending on the setting of the LP_STANDBY_SEL bit. #GUID-117B0898-2FEC-4E9D-9F33-06019819BC63/SLVSEA7991 lists the conditions to generate the OFF requests and the corresponding destination state. OFF Requests EVENT DEBOUNCE LP_STANDBY_SEL BIT SETTING DESTINATION STATE nPWRON (pin) (long press key event) 8 s LP_STANDBY_SEL = 0 STANDBY LP_STANDBY_SEL = 1 LP_STANDBY ENABLE (pin) 8 µs LP_STANDBY_SEL = 0 STANDBY LP_STANDBY_SEL = 1 LP_STANDBY I2C_TRIGGER_0 NA LP_STANDBY_SEL = 0 STANDBY LP_STANDBY_SEL = 1 LP_STANDBY The long press key event occurs when the nPWRON pin stays low for longer than tLPK_TIME while the device is in a mission state. When the nPWRON or ENABLE pin is used as the OFF request, the device wakes up from the STANDBY or the LP_STANDBY state through the ON request initiated by the same pin. The NPWRON_START_MASK or the ENABLE_MASK must remain low in this case to allow the detection of the ON request initiated by the pin. If the device needs to enter the LP_STANDBY state through the OFF request, it is important that the state of the nPWRON or ENABLE pin must remain the same until the state transition is completed. Failure to do so may result in unsuccessful wake-up from the LP_STANDBY state when the pin re-initiates On request. Using the I2C_TRIGGER_0 bit as the OFF request enables the device to wake up from the STANDBY or the LP_STANDBY states through the detection of LP_WKUPn/WKUPn pins, as well as RTC alarm or timer interrupts. To enable this feature, the device must set the I2C_TRIGGER_0 bit to '1' while the NSLEEPn signals are masked, and the ON request (initialized by the nPWRON or ENABLE pins) must remain active. Also the interrupt bits ENABLE_INT, FSD_INT and the GPIOx_INT bits (for the GPIOx pins assigned as WKUP1 or WKUP2) must be cleared before setting the I2C_TRIGGER_0 bit to '1'. NSLEEP1 and NSLEEP2 Functions The SLEEP requests are activated through the assertion of nSLEEP1 or nSLEEP2 pins that are the secondary functions of the 11 GPIO pins. These pins can be selected through GPIO configuration using the GPIOx_SEL register bits. If the nSLEEP1 or nSLEEP2 pins are not available, the NSLEEP1B and NSLEEP2B register bits can be configured in place for their functions. The input of nSLEEP1 pin and the state of the NSLEEP1B register bit are combined to create the NSLEEP1 signal through an OR function. Similarly for the input of the nSLEEP2 pin and the NSLEEP2B register bit as they are combined to create the NSLEEP2 signal. A 1 → 0 logic level transition of the NSLEEP signal generates a sleep request, while a 0 → 1 logic level transition reverses the sleep request in the example PFSM from . When a NSLEEPn signal transitions from 1 → 0, it generates a sleep request to go from a higher power state to a lower power state. When the signal transitions from 0 → 1, it reverses the sleep request and returns the device to the higher power state. The NSLEEP1 signal is designed to control the SoC supply rails. The NSLEEP2 signal is designed to control the MCU supply rails. When NSLEEP1 signal changes from 1 → 0, depending on the state of NSLEEP2, the TPS6593-Q1 device exits ACTIVE state and enters either the MCU ONLY or the S2R states. When NSLEEP2 signal changes from 1 → 0, the device enters the S2R state regardless the state of NSLEEP1. When the NSLEEP2 input signal changes from 0 →1, the MCU supply rails are enabled and the device exits S2R state. Depending on the state of NSLEEP1 signal, the device enters either the MCU ONLY or the ACTIVE state. In order for the system to function correctly, the MCU rails must be enabled when the NSLEEP1 input signal changes from 0 →1, which enables the SOC supply rails. NSLEEP1 0 →1 transition is ignored if NSLEEP2 is 0. The NSLEEPn_MASK bit can be used to mask the sleep request associated with the corresponding NSLEEPn signal. When the NSLEEPn_MASK = 1, the corresponding NSLEEPn signal is ignored. shows how the combination of the NSLEEPn signals and NSLEEPn_MASK bits creates triggers A/B/C/D to the FSM to control the power state of the device. The states of the resources during ACTIVE, SLEEP, and DEEP SLEEP/S2R states are defined in the LDOn_CTRL and BUCKn_CTRL registers. For each resource, a transition to the MCU ONLY or the DEEP SLEEP/S2R states is controlled by the FSM when the resource is associated to the SLEEP or DEEP SLEEP/S2R states. shows the corresponding state assignment based on the state of the NSLEEPn and their corresponding mask signals using the example PFSM from .

Any one of these GPIO pins when configured as an input pin can be configured to wake up the device by setting GPIOn_SEL bit to select the WKUP1 or WKUP2 functions. In the example PFSM depicted in , when a GPIO pin is configured as a WKUP1 pin, a rising or falling edge detected at the input of this pin (configurable by the GPIOn_FALL_MASK and the GPIOn_RISE_MASK bits) wakes up the device to the ACTIVE state. Likewise if a GPIO pin is configured as a WKUP2 pin, a detected edge wakes up the device to the MCU ONLY state. If multiple edge detections of WKUP signals occur simultaneous, the device goes to the state in the following priority order: ACTIVE MCU ONLY When a valid edge is detected at a WKUP pin, the nINT pin generates an interrupt to signal the MCU of the wake-up event, and the GPIOx_INT interrupt bit is set. The wake request remains active until the GPIOx_INT bit is cleared by the MCU. While the wake request is executing, the device does not react to sleep requests to enter a lower power state until the corresponding GPIOx_INT interrupt bit is cleared to cancel the wake request. After the wake request is canceled, the device returns to the state indicated by the NSLEEP1 and NSLEEP2 signals as shown in . LP_WKUP Pins for Waking Up from LP STANDBY The LP_WKUP functions are activated through the edge detection of LP_WKUP pins, configurable as secondary functions of GPIO3 and GPIO4. They are specially designed to wake the device up from the LP STANDBY state when a high speed wake-up signal is detected. Similar to the WKUP1 and WKUP2 pins, when GPIO3 or GPIO4 pin is configured as an LP_WKUP1 pin, a rising or falling edge detected at the input of this pin (configurable by the GPIOn_FALL_MASK and the GPIOn_RISE_MASK bits) wakes up the device to the ACTIVE state. Likewise, if the pin is configured as an LP_WKUP2 pin, a detected edge wakes up the device to the MCU ONLY state. If multiple edge detections of LP_WKUP signals occur simultaneously, the device goes to the state in the following priority order: ACTIVE MCU ONLY Due to a digital control erratum in the device, the ENABLE_MASK/NPWRON_START_MASK bit must be set to '1' before the device enters LP_STANDBY state in order for the LP_WKUP2 pin to correctly wake up the device to the MCU_ONLY state. The TPS6593-Q1 device supports limited CAN wake-up capability through the LP_WKUP1/2 pins. When an input signal (without deglitch) with logic level transition from high-to-low or low-to-high with a minimum pulse width of tWK_PW_MIN is detected on the assigned LP_WKUP1/2 pins, the device wakes up asynchronously and executes the power up sequence. CAN-transceiver RXD- or INH-outputs can be connected to the LP_WKUP pin. If RXD-output is used, it is assumed that the transceiver RXD-pin IO is powered by the transceiver itself from an external supply when TPS6593-Q1 is in the LP_STANDBY state. If INH-signal is used it has to be scaled down to the recommenced GPIO input voltage level specified in the electrical characteristics table. In this PFSM example, the device can wake up from the LP_STANDBY state through the detection of LP_WKUP pins only if it enters the LP_STANDBY state through the TRIGGER_I2C_0 OFF request while the NSLEEPn signals are masked, and the on request initialized by the nPWRON/ENABLE pin remains active. Once a valid wake-up signal is detected at the LP_WKUP pin, it is handled as a WAKE request. The nINT pin generates an interrupt to signal the MCU of the wake-up event, and the corresponding GPIOx_INT interrupt bit is set. The wake request remains active until the interrupt bit is cleared by the MCU. shows how the device returns to the state indicated by the NSLEEP1 and NSLEEP2 signals after the wake request is canceled. illustrates the valid wake-up signal at the LP_WKUP1/2 pins, and the generation and clearing of the internal wake-up signal. CAN Wake-Up Timing Diagram Error Handling Operations The FSM engine of the TPS6593-Q1 device is designed to handle the following types of errors throughout the operation: Power Rail Output Error Boot BIST Error Runtime BIST Error Catastrophic Error Watchdog Error Error Signal Monitor (ESM) Error Warnings Power Rail Output Error A power rail output error occurs when an error condition is detected on the output rails of the device that are used to power the attached MCU or SoC. These errors include the following: Rails not reaching or maintaining within the power good voltage level threshold. A short condition that is detected at a regulator output. The load current that exceeds the forward current limit. The BUCKx_GRP_SEL, LDOn_GRP_SEL and VCCA_GRP_SEL registers are used to configure the rail group for all of the Bucks, LDOs, and the voltage monitors that are available for external rails. The selectable rail groups are MCU rail group, SoC rail group, or OTHER rail group. The TPS6593-Q1 device is designed to react differently when an error is detected from a power resource assigned to the different rail groups. shows how the SOC_RAIL_TRIG[1:0], MCU_RAIL_TRIG[1:0], and OTHER_RAIL_TRIG[1:0] register bits are used as the Immediate Shutdown Trigger Mask, Orderly Shutdown Trigger Mask, MCU Power Error Trigger Mask, or the SoC Power Error Trigger Mask. The settings of these register bits determine the error handling sequence that the assigned groups of rails perform in case of an output error. The PFSM engine can be configured to execute the appropriate error handling sequence for the following error handling sequence options: immediate shutdown, orderly shutdown, MCU power error, or SOC power error. For example, if an immediate shutdown sequence is assigned to the MCU rail group through the MCU_RAIL_TRIG[1:0] register bits, any failure detected in this group of rails causes the IMMEDIATE_SHUTDOWN trigger to be executed. This trigger is expected to start the immediate shutdown sequence and cause the device to enter the SAFE RECOVERY state. The device immediately resets the attached MCU and SoC by driving the nRSTOUT and nRSTOUT_SoC (GPO1 or GPIO11) pins low. All of the power resources assigned to the MCU and SOC shut down immediately without a sequencing order. The nINT pin signals that an MCU_PWR_ERR_INT interrupt event has occurred and the EN_DRV pin is forced low. If the error is recoverable within the recovery time interval, the device increments the recovery count, returns to INIT state, and reattempts the power up sequence (if the recovery count has not exceeded the counter threshold). If the recovery count has already exceeded the threshold, the device stays in the SAFE RECOVERY state until VCCA voltage is below the VCCA_UVLO threshold and the device is power-cycled. The power resources assigned to the SoC rail group are typically assigned to the SOC power error handling sequence. In this PFSM example depicted in , when a power resource in this group is detected, the PFSM typically causes the device to execute the shutdown of all the resources assigned to the SoC rail group, and the device enters the MCU ONLY state. The device immediately resets the attached SoC by toggling the nRSTOUT_SoC (GPO1 or GPIO11) pin. The reset output to the MCU and the resources assigned to the MCU rail group remain unchanged. The EN_DRV pin also remains unchanged, and the nINT pin signals that an SOC_PWR_ERR_INT interrupt event has occurred. To recover from the MCU_ONLY state after a SOC power error, the MCU software must set NSLEEP1 signal to '0' while NSLEEP2 signal remains '1'. This action signals TPS6593-Q1 that MCU has acknowledged the SOC power error, and is ready to return to normal operation. MCU can then set the NSLEEP1 signal back to '1' for the device to return to ACTIVE state and reattempt the SoC power up. Refer to for information regarding the setting of the NSLEEP1 and NSLEEP2 signals. The power resources used for peripheral devices in the system, for which no error-handling action is required, the rail mapping needs to be selected as "no group assigned". Catastrophic Error Catastrophic errors are errors that affect multiple power resources such as errors detected in supply voltage, LDOVINT supply for control logic, errors on internal clock signals, device temperature passing the thermal shutdown threshold, error detected on the SPMI bus, or an error detected in the PFSM sequence. Following errors are grouped as severe errors: VCCA > OVP threshold Junction temperature > immediate shutdown level Error in PFSM Sequence For these above listed errors, depending on the setting of bits SEVERE_ERR_TRIG[1:0], an immediate or orderly shutdown condition is created. The PFSM executes the corresponding sequence for the IMMEDIATE_SHUTDOWN trigger or the ORDERLY_SHUTDOWN trigger and enters the SAFE RECOVERY state. Following errors are grouped as moderate errors: Junction temperature > orderly shutdown level BIST failure CRC error in register map Recovery counter exceeding the threshold value Error on SPMI bus Readback error on nRSTOUT pin or nINT pin For these above listed errors, depending on the setting of bits MODERATE_ERR_TRIG[1:0], an immediate or orderly shutdown condition is created. The PFSM executes the corresponding sequence for the IMMEDIATE_SHUTDOWN trigger or the ORDERLY_SHUTDOWN trigger and enters the SAFE RECOVERY state. For following errors, the device performs an immediate shutdown and resets all internal logic circuits: VCCA < UVLO threshold Error on LDOVINT supply Errors on internal clock signals Unrecoverable CRC error in the SRAM memory of the PFSM For all of the above listed errors, the device resets the attached MCU and SoC by driving the nRSTOUT and the GPIO pin used as nRSTOUT_SoC (GPO1 or GPIO11) pins low. All of the power resources assigned to the attached MCUand SOC are shut down. The nINT pin is driven low to signal an interrupt event has occurred, and the EN_DRV pin is forced low. Watchdog (WDOG) Error Watchdog (WDOG) describes details about the Watchdog (WDOG) errors detection mechanisms. Warnings Warning are non-catastrophic errors. When such an error occurs while the device is in the operating states, the device detects the error and handles the error through the interrupt handler. These are errors such as thermal warnings, I2C, or SPI communication errors, or power resource current limit detection while the output voltage still maintains within the power good threshold. When these errors occur, the nINT pin is driven low to signal an interrupt event has occurred. The device remains in the operation state and the state of the EN_DRV pin, the power resources, and the reset outputs remain unchanged. The power resource current limit detection can, by setting bit EN_ILIM_FSM_CTRL=1, be configured such that it is handled as a Power Rail Output Error as described in . Device Start-up Timing shows the timing diagram of the TPS6593-Q1 after the first supply detection. Device Start-up Timing Diagram tINIT_REFCLK_LDO is the start-up time for the reference block. tINIT_NVM_ANALOG is the time for the device to load the default values of the NVM configurable registers from the NVM memory, and the start-up time for the analog circuits in the device. tINIT_REFCLK_LDO and tINIT_NVM_ANALOG are defined in the electrical characteristics table. BOOT_BIST is the sum of tLBISTrun (which is defined in the electrical characterization tables) and a less than 60us time-interval needed for the cyclic redundancy check on the register map and the SRAM. The Power Sequence time is the total time for the device to complete the power up sequence. Please refer to for more details. The reset delay time is a configurable wait time for the nRSTOUT and the nRSTOUT_SoC release after the power up sequence is completed. Power Sequences A power sequence is an automatic preconfigured sequence the TPS6593-Q1 device applies to its resources, which include the states of the BUCKs, LDOs, 32-kHz clock and the GPIO output signals. For a detailed description of the GPIOs signals, please refer to General-Purpose I/Os (GPIO Pins). shows an example of a power up transition followed by a power down transition. The power up sequence is triggered through a valid on request, and the power down sequence is trigger by a valid off request. The resources controlled (for this example) are: BUCK3, LDO1, BUCK2, LDO2, GPIO1 , LDO4, and LDO3. The time between each resource enable and disable (TinstX) is also part of the preconfigured sequence definition. A resource not assigned to any power sequence remains in off mode during the power-up sequence. The attached MCU or SoC can enable and configure this resource independently when the power-up sequence completes. Also the EN_DRV remains low during the power-up sequence. The attached MCU or SoC can release the EN_DRV pin by setting the ENABLE_DRV bit (requires running watchdog, ESM started and no pending interrupt bits). Power Sequence Example As the power sequences of the TPS6593-Q1 device are defined according to the processor requirements, the total time for the completion of the power sequence varies across various system definitions. First Supply Detection The TPS6593-Q1 device can be configured to automatically start up from a first supply-detection (FSD) event detection. This feature is enabled by setting the FSD_MASK register bit to '0', and setting the NPWRON_SEL[1:0] registers bits to '10' or '11' to mask the functionality of the nPWRON/ENABLE pin. When the device is powered up from the NO SUPPLY state, the FSD detection is validated after the NVM default for this feature is loaded into the device memory. When the FSD feature is enabled, the PMIC immediately powers up from the NO SUPPLY state to an operation state, configured by the STARTUP_DEST[1:0] bits when VCCA > VCCA_UV, while VCCA_UV gating is performed, and only when VCCA voltage monitoring is enabled (VCCA_VMON_EN = 1). After the device arrives the corresponding STARTUP_DEST[1:0] operation state, the MCU must setup the NSLEEP1 and NSLEEP2 signals accordingly before clearing the FSD_INT interrupt. Once the interrupt is cleared, the device either stays in the current state or moves to the destination state according to the state of the NSLEEP1 and NSLEEP2 signals as specified in . Register Power Domains and Reset Levels The TPS6593-Q1 registers are defined by the following categories: LDOVINT registers LDOVRTC registers (registers in RTC domain) LDOVINT registers The LDOVINT registers are powered by the internal LDOVINT, and retain their values until the device enters the LP_STANDBY state or the BACKUP state after the device was fully powered up and in operation. When this occurs, LDOVINT is powered off, all LDOVINT registers (including the VSET registers which store the output voltage levels for all of the external power rails) are reset. As the device re-enters the INIT state from a wake up signal or an On-request, the registers powered by the LDOVINT are re-written with the default values from NVM (Non-Volatile Memory). All registers in the device, except the LDOVRTC registers (registers in RTC domain), are powered by LDOVINT. LDOVRTC registers (registers in RTC domain) The LDOVRTC registers (registers in RTC domain) retain their values until a Power-On-Reset (POR) occurs. POR occurs when the device loses supply power and enters the NO SUPPLY state. When this occurs, LDOVRTC is powered off, and all LDOVRTC registers are reset. Following are the LDOVRTC registers: All RTC registers RTC and Crystal Oscillator bits Status registers for the following events: TSD and RTC reset Control registers for PWRON/ENABLE, GPIO3, and GPIO4 pins (for wake signal monitor during LP_STANDBY state) Following interrupt registers: FSD_INT RECOV_CNT_INT TSD_ORD_INT TSD_IMM_INT PFSM_ERR_INT VCCA_OVP_INT ESM_MCU_RST_INT ESM_SOC_RST_INT WD_RST_INT WD_LONGWIN_TIMEOUT_INT NPWRON_LONG_INT Multi-PMIC Synchronization A 20220110 Changed all instances of legacy terminology into "controller" and "target", also in all sub-sectionsyes A multi-PMIC synchronization scheme is implemented in the TPS6593-Q1 device to synchronize the power state changes with other PMIC devices. This feature consolidates and simplifies the IO control signals required between the application processor or the microcontroller and multiple PMICs in the system. The control interface consists of an SPMI protocol that communicates the next power state information from the primary PMIC to up to 5 secondary PMICs, and receives feedback signal from the secondary PMICs to indicate any error condition or power state information. is the block diagram of the power state synchronization scheme. The primary PMIC in this block diagram is responsible for broadcasting the synchronous system power state data, and processing the error feedback signals from the secondary PMICs. The primary PMIC is the controller device on the SPMI bus, and the secondary PMICs are the target devices on the SPMI bus. Multi-PMIC Power State Synchronization Block Diagram In this scheme, each primary and secondary PMIC runs on its own system clock, and maintains its own register map. Each PMIC monitors its own activities and pulls down the open-drain output of nINT or PGOOD pin when errors are detected. The microprocessor must read the status bits from each PMIC device through the I2C or SPI interface to find out the source of the error that is reported. To synchronize the timing when entering and exiting from the LP_STANDBY state, the VOUT_LDOVINT of the TPS6593-Q1 device must be connected to the ENABLE input of the secondary PMICs, which are the target devices in the SPMI interface bus. illustrates the pin connections between the primary, the secondary, and the application processor or the System-on-Chip. Multi-PMIC Pin Connections The power sequencer of the multiple PMICs are synchronized at the beginning of each power up and power down sequence; a variation in the sequence timing, however, is still possible due to the ±5% clock accuracy of the independent system clocks on the primary and secondary PMICs. The worst-case sequence timing variation from different PMIC rails is up to ±10% of the target delay time. illustrates the creation of this timing variation between PMICs. Multi-PMIC Rail Sequencing Timing Variation SPMI Interface System Setup An SPMI interface in the TPS6593-Q1 device is utilized to communicate the power state transition across multiple PMICs in the system. The SPMI interface contains a controller block and a target block. There is only one PMIC, which is the primary PMIC, that acts as SPMI controller in any given system. As the SPMI controller it initiates SPMI interface BIST and executes periodic checking of the SPMI bus health. The primary PMIC has a controller-ID (CID)= 1. The target block of SPMI interface in the primary PMIC device is activated as well, in order to receive SPMI communication messages from the secondary PMICs. The primary PMIC has a target-ID (TID) = 0101. Each secondary PMIC on the SPMI network only has the target block of its SPMI interface enabled. There cannot be more than five secondary PMICs in the system. The target-IDs (TIDs) for the five secondary PMICs are: 1st target device: 0011 2nd target device: 1100 3rd target device: 1001 4th target device: 0110 5th target device: 1010 All devices in the SPMI network listen to the group target-ID (GTID): 1111. This address is used to communicate all power state transition information in broadcast mode to all connected devices on the SPMI bus. Transmission Protocol and CRC The communication between the devices on the network utilizes Extended Register Write command to GTID address 1111 with byte length of 2. Sequence format complies with MIPI SPMI 2.0 specification. First data frame carries the data payload of 5 bits and 3 filler bits. Communication over the SPMI interface may contain information regarding the power state transition or the unique TID of one or more target devices. In the case of power state information, the data payload contains 5 bits of Trigger ID information and 3 trigger state bits. In the case of TID information, all 8 bits contain the TID of the target device. Second data frame carries 8 bits of CRC information. CRC polynomial used is X8 + X2 + X + 1. CRC is calculated over the SPMI command frame, the address frame, and the first data frame (which contains the payload and excludes the parity bits in these three frames). shows the data format of the SPMI Extended Register Write Command. SPMI Extended Register Write Command Operation with Transmission Errors If the receiving device detects a parity or CRC error in the incoming sequence it responds with negative ACK/NACK per SPMI standard. If the transmitting device sees NACK response, it tries to resend the message as many times as indicated by SPMI_RETRY_LIMIT register bits. After that it considers the SPMI bus inoperable, sets SPMI_ERR_INT interrupt and goes to the safe recovery state and executes an orderly shutdown. Bus arbitration requests do not count as failed attempts if a target device loses bus arbitration. SPMI_RETRY_LIMIT counter is reset after each successful transmission by the device. If a target device has determined that SPMI does not work reliably it does not respond to any SPMI commands anymore until power-on-reset event has occurred. This "no-response" behavior is to prevent continued operation in a situation where SPMI is unreliable. If a target device does no longer respond to any SPMI command, the controller device on the SPMI bus detects a missing target device on the network during the periodic testing of SPMI bus. The target device then internally handles the SPMI error condition per error handling rules set for the device (in general executing an orderly shutdown). SPMI block signals to the device that SPMI bus error has occurred after the retry limit has been exceeded. Transmitted Information The SPMI bus is used to carry two types of information: PFSM Trigger ID between the SPMI controller and target devices TID from SPMI target devices to SPMI controller device The SPMI controller device reads the TID of the target devices periodically to check the health of the interface. Exchanging Trigger IDs for the power state transition is sufficient to keep the PFSMs of all the devices on the SPMI network in synchronization. Device interrupts explain reason for the power state transitions. SPMI Target Device Communication to SPMI Controller Device An SPMI target device communicates to the SPMI controller device and any other SPMI target devices, only if there is an internal error that is not SPMI related. The target device initiates the error communication using Arbitration Request with A-bit as defined in the SPMI 2.0 specification. SPMI 2.0 protocol manages the situation with multiple target devices requesting error communication at the same time, by using the target arbitration process as described in SPMI 2.0 specification. Once the SPMI target device wins the arbitration using the A-bit protocol, it performs an Extended Register Write command to Group Target ID (GTID) address 1111 by using the protocol described in for communicating PFSM trigger ID. Incomplete Communication from SPMI Target Device to SPMI Controller Device In case the SPMI controller device detects an arbitration request on the SPMI interface, but the received sequence has an error or is incomplete, the SPMI controller device immediately performs the SPMI Built-In Self-Test (SPMI-BIST). If this SPMI-BIST fails, the SPMI controller device executes the error handling for the SPMI error. If the SPMI-BIST passes successfully, the SPMI controller device resumes normal operation. SPMI-BIST Overview The SPMI-BIST is performed during BIST state and regularly during runtime operation. below illustrates how the SPMI-BIST operates during device power-up. SPMI-BIST Operation After the input power is detected and verified to be at the correct level, the TPS6593-Q1 initializes itself by reading the NVM and performs all actions that are needed to prepare for operation. After this initialization, the TPS6593-Q1 enters the BOOT BIST state, in which the internal logic performs a series of tests to verify that the TPS6593-Q1 device is OK. As part of this test, the SPMI- BIST is performed. After it is completed successfully, the TPS6593-Q1 device goes to the standby state and waits for further signals from the system to initiate the power-up sequence of the processor. A valid on request initiates the processor power-up sequence. The controller device communicates this event through the SPMI bus to all of the target devices. After that, the power-up sequence is executed and TPS6593-Q1 enters the configured mission state. SPMI Bus during Boot BIST and RUNTIME BIST During Boot BIST and RUNTIME BIST, both the Logic BIST (LBIST) on the SPMI logic and the SPMI-BIST are performed to check correct operation of the SPMI bus. The LBIST is performed first before the SPMI-BIST during BOOT BIST and RUNTIME BIST. The SPMI-BIST is implemented by reading TID from each target device on the SPMI bus into the controller device, and ensuring they are unique and match the expected amount of target devices. This process of checking the TID of each target device ensures that: All SPMI target devices are present in the system as expected The SPMI logic blocks are working on the SPMI controller device and all of the SPMI target devices The pins and wires on the ICs and PCB are in working order The SPMI-BIST is initiated by the SPMI controller block in the primary PMIC by writing a request to all SPMI target device(s) (using GTID) to send their TIDs to the SPMI controller block of the primary PMIC. Upon receiving this command from the SPMI controller device, the SPMI target devices request SPMI bus arbitration using the SR-bit protocol. Upon winning the bus arbitration the SPMI target devices transmit their TID into the SPMI target block of the primary PMIC. The SPMI controller block of the primary PMIC contains a list of all SPMI target device(s) on the SPMI bus and their TIDs in the register set. The SPMI controller block of the primary PMIC reads the TID from each SPMI target device and compares the result with the stored TID for the corresponding SPMI target device. The SPMI controller device has to ensure that every non-zero TID on its list is returned, in order to support use cases in which there are two or more identical SPMI target devices, with same TID, in the system. In these cases, it is mandatory that the expected number of the same TIDs is returned. If no identical PMICs are to be used, then a return of the same TID multiple times is an error due to incorrect assembly of identical PMICs onto the PCB. An all-zero TID stored in the list of the primary PMIC indicates that there are no SPMI target device(s) present on the SPMI Bus. Periodic Checking of the SPMI The SPMI controller block in the primary PMIC executes the SPMI-BIST periodically while device is operating. The time-period after the SPMI-BIST is repeated according factory-configured settings during the device boot time, and after the device reaches mission states. The factory-configured settings of this SPMI-BIST time period must be the same for all PMICs on the same SPMI network. The SPMI target devices on the SPMI bus expect a request for sending its TID from the SPMI controller device within 1.5x the factory-configured period . This factor 1.5x provides enough margin for clock uncertainty between the SPMI controller device and the SPMI target device. During mission state operation, the SPMI controller device expects the SPMI target devices to respond to the TID request within the factory-configured polling time-out period . In other words, from the polling start command each SPMI target device must respond within this factory-configured time interval. During boot time or when the device enters Safe Recovery state, to prevent the SPMI controller device from polling the SPMI target devices too often while one or more of these recovering from a system error such as a thermal shutdown event, the device sets a longer timeout period that allows the SPMI target devices to respond to the SPMI controller device before he SPMI controller device reports an error. If one or more devices on the SPMI bus cause a violating of the polling time-out period either during start-up or during normal operation, the SPMI controller block in the affected PMIC(s) sets a SPMI error trigger signal to the PFSM of the affected PMIC(s), causing a complete shutdown of the affected PMIC(s). As a result, the affected PMIC(s) no longer respond on the SPMI bus, which in turn is detected by the SPMI controller block off the non-affected PMICs on the SPMI bus. The SPMI controller block in these PMICs sets an SPMI error to the PFSM in these PMICs, causing a complete shutdown of these PMICs. Therefore, all PMICs are finally shutdown if one or more devices on the SPMI bus cause a violating of the polling time-out period . SPMI Message Priorities The SPMI Bus uses the protocol priority levels listed in #GUID-F91E50E4-0CEA-4F17-B748-4E3A03F33999/SLVSE824332 for each type of communication message. SPMI Message Types and Priorities SPMI protocol priority level Name of priority level in SPMI standard Message types Highest A-bit arbitration State transition messages from target device(s) to controller device priority arbitration State transition messages from controller device to target device(s) SR-bit arbitration target device TID to controller device Lowest secondary arbitration Controller device request of TIDs from target device(s) Device Functional Modes Device State Machine The TPS6593-Q1 device integrates a finite state machine (FSM) engine that manages the state of the device during operating state transitions. The device supports NVM-configurable mission states with configurable input triggers for transitions between states. Any resources, including the 5 BUCK regulators, 4 LDO regulators, and all of the digital IO pins including the 11 GPIO pins on the device can be controlled during power sequencing. When a resource is not controlled or configured through a power sequence, the resource is left in the default state as pre-configured by the NVM. Each resource can be pre-configured through the NVM configuration, or re-configured through register bits. Therefore, the user can statically control the resource through the control interfaces (I2C or SPI), or the FSM can automatically control the resource during state sequences. The FSM is powered by an internal LDO that is automatically enabled when VCCA supply is available to the device. Ensuring that the VCCA supply is the first supply available to the device is important to ensure proper operation of all the power resources as well as the control interface and device IOs. There are three parts of the FSM that control the operational modes of the TPS6593-Q1 device: Fixed Device Power Finite State Machine (FFSM) Pre-configurable Finite State Machine (PFSM) for Mission States (ACTIVE, MCU_ONLY, S2R, DEEP_SLEEP) Error Handling Operations The PFSM provides configurable rail and voltage monitoring sequencing utilizing instructions in configuration memory. This flexibility enables customers to alter power-up sequences on a platform basis. The FFSM handles the majority of fixed functionality that is internally mandated and common to all platforms. Fixed Device Power FSM The Fixed Device Power portion of the FSM engine manages the power up of the device before the power rails are fully enabled and ready to power external loadings, and the power down of the device when in the event of insufficient power supply or device or system error conditions. While the device is in one of the Hardware Device Powers states, the ENABLE_DRV bit remains low. The definitions and transition triggers of the Device Power States are fixed and cannot be reconfigured. Following are the definitions of the Device Power states: NO SUPPLY The device is not powered by a valid energy source on the system power rail. The device is completely powered off. BACKUP (RTC backup battery) The device is not powered by a valid supply on the system power rail (VCCA < VCCA_UVLO); a backup power source, however, is present and is within the operating range of the LDOVRTC. The RTC clock counter remains active in this state if it has been previously activated by appropriate register enable bit. The calendar function of the RTC block is activated, but not accessible in this state. Customer has the option to enable the shelf mode by disconnecting the VCCA supply completely, even while the backup battery is connected to the VBACKUP pin. The shelf mode forces the device to skip the BACKUP state and enters the NO SUPPLY state under VCCA_UVLO condition to reduce current draining from the backup battery. LP_STANDBY The device can enter this state from a mission state after receiving a valid OFF request or an I2C trigger, and the LP_STANDBY_SEL= 1. When the device is in this state, the RTC clock counter and the RTC Alarm or Timer Wake-up functions are active if they have been previously activated by appropriate register enable bit. Low Power Wake-up input monitor in the LDOVRTC domain (LP_WKUP secondary function through GPIO3 or GPIO4) and the on request monitors are also enabled in this state. When a logic level transition from high-to-low or low-to-high with a minimum pulse length of tLP_WKUP is detected on the assigned LP_WKUP pin, or if the device detects a valid on-request or a wake-up signal from the RTC block, the device proceeds to power up the device and reach the default mission state. More details regarding the LP_WAKE function can be found in . INIT The device is powered by a valid supply on the system power rail (VCCA ≥ VCCA_UV). If the device was previously in LP_STANDBY state, it has received an external wake-up signal at the LP_WKUP1/2 pins, the RTC alarm or timer wake-up signal, or an On Request from the nPWRON/ENABLE pin. Device digital and monitor circuits are powered up. The PMIC reads its internal NVM memory in this state and configures default values to registers, IO configuration and FSM accordingly. BOOT BIST The device is running the built-in self-test routine that includesThe ABIST on the voltage monitor circuits for the BUCK regulators, the LDO regulators is performed after the start-up of these regulators. The ABIST on the VMON1 and VMON2 is performed after these voltage monitors are enabled. See Voltage Monitors. An option is available to shorten the device power up time from the NO_SUPPLY state by setting the NVM bit FAST_BOOT_BIST = '1' to skip the LBIST. Software can also set the FAST_BIST = '1' to skip LBIST after the device wakes up from the LP STANDBY state. When the device arrives at this state from the SAFE_RECOVERY state, LBIST is automatically skipped if it has not previously failed. If LBIST failed, but passed after multiple re-tries before exceeding the recovery counter limit, the device powers up normally. The following NVM bits are pre-configured options to enable or disable parts of the CRC tests if further sequence time reduction is required (please refer to the user's guide of the orderable part number): REG_CRC_EN = '0': disables the register map and SRAM CRC check Note: the BIST tests are executed as parallel processes, and the longest process determines the total BIST duration the ABIST on the voltage monitor circuits of the BUCKx regulator, LDOn regulators, VMON1 and VMON2 is performed individually after these voltage monitors are enabled. See Voltage Monitors) RUNTIME BIST A request was received from the MCU to exercise a run-time built-in self-test (RUNTIME_BIST) on the device. No rails are modified and all external signals, including all I2C or SPI interface communications, are ignored during the RUNTIME_ BIST. During the RUNTIME_BIST, the device performs the same self-test routines as listed for the BOOT_BIST state. Furthermore, during RUNTIME_BIST the device performs the ABIST routine on all enabled voltage monitor circuits. If the device passed BIST, it resumes the previous operation. If the device failed BIST, it shuts down all of the regulator outputs and proceed to the SAFE RECOVERY state. In order to avoid a register CRC error, all register writes must be avoided after the request for the BIST operation until the device pulls the nINT pin low to indicate the completion of BIST. The results of the RUNTIME_BIST are indicated by the BIST_PASS_INT or the BIST_FAIL_INT interrupt bits.After completion of the RUNTIME_BIST, the LDOx_UV detections are masked for a time-interval equal to the configured LDOx ramp-up time (25 mV/μs or 3 mV/μs according configuration bit LDOx_SLOW_RAMP). The actual LDOx output voltages are not affected by this masking of the LDOx_UV detections. SAFE RECOVERY The device meets the qualified error condition for immediate or ordered shutdown request. If the error is recovered within the recovery time interval or meets the restart condition, the device increments the recovery counter, and returns to INIT state if the recovery counter value does not exceed the threshold value. Until a supply power cycle occurs, the device stays in the SAFE RECOVERY state if one of the following conditions occur: the recovery counter exceeds the threshold value the die temperature cannot be reduced to less than TWARN level VCCA stays above OVP threshold When multiple system conditions occur simultaneously that demand power state arbitration, the device goes to the higher priority state according to the following priority order: NO SUPPLY BACKUP SAFE_RECOVERY LP_STANDBY MISSION STATES shows the power transition states of the FSM engine. State Diagram for Device Power States Register Resets and NVM Read at INIT State Several registers inside the TPS6593-Q1 have pre-configured default values that are stored in the NVM of the TPS6593-Q1. These registers are referred to as NVM pre-configured registers. When the device transitions from the LP_STANDBY or the SAFE_RECOVERY to the INIT state, based on FIRST_STARTUP_DONE bit, the registers are reset and the NVM is read. When the FIRST_STARTUP_DONE is '0', registers which are not in the RTC domain are reset, and all of the NVM pre-configured registers including the ones in the RTC domain, are loaded from the NVM. When the FIRST_STARTUP_DONE bit is set to '1', typically after the initial power up from a supply power cycle, the registers in the RTC domain are not reset, and the NVM pre-configured registers in the RTC domain are not re-loaded from the NVM. Setting the FIRST_STARTUP_DONE bit prevents the control and status bits stored in the RTC domain registers from being over written. Register resets and NVM read at INIT state FIRST _STARTUP_DONE NVM pre-configured registers in RTC Domain Registers without NVM pre-configuration in RTC Domain Other NVM pre-configured registers Registers without NVM pre-configuration 0 Defaults read from NVM No changes Reset and defaults read from NVM Reset 1 No changes No changes Reset and defaults read from NVM Reset Below are the NVM pre-configured register bits in the RTC domain: GPIO3_CONF and GPIO4_CONF registers, except the GPIOn_DEGLITCH_EN bits GPIO3_RISE_MASK, GPIO3_FALL_MASK, GPIO4_RISE_MASK, and GPIO4_FALL_MASK bits NPWRON_CONF register except ENALBE_DEGLITCH_EN and NRSTOUT_OD bits FSD_MASK, ENABLE_MASK, NPWRON, START_MASK, and NPWRON_LONG_MASK bits STARTUP_DEST, FAST_BIST, LP_STANDBY_SEL, XTAL_SEL, and XTAL_EN bits PFSM_DELAYn, and RTC_SPARE_n bits Below are the register bits without NVM pre-configuration in the RTC domain: FIRST_STARTUP_DONE bit SCRATCH_PAD_n bits All of RTC control and configuration registers Pre-Configurable Mission States When the device arrives at a mission state, all rail sequencing is controlled by the pre-configurable FSM engine (PFSM) through the configuration memory. The configuration memory allows configurations of the triggers and the operation states that together form the configurable sub state machine within the scope of mission states. This sub state machine can be used to control and sequence the different voltage outputs as well as any GPIO outputs that can be used as enable for external rails. When the device is in a mission state, it has the capacity to supply the processor and other platform modules depending on the power rail configuration. The definitions and transition triggers of the mission states are configurable through the NVM configuration. Unlike the user registers, the PFSM definition stored in the NVM cannot be modified during normal operation. When the PMIC determines that a transition to another operation state is necessary, it reads the configuration memory to determine what sequencing is needed for the state transition. Furthermore, the PFSM has four storage registers, further referred to as PFSM storage registers (R0-3). shows how the trigger signals for each state transition can come from a variety of interface or GPIO inputs, or potential error sources. shows how the device processes all of the possible error sources inside the PFSM engine, a hierarchical mask system is applied to filter out the common errors that can be handled by interrupt only, and categorize the other error sources as Severe Global Error, Moderate Global Error, and so forth. The filtered and categorized triggers are sent into the PFSM engine, that then determines the entry and exit condition for each configured mission state. Error Source Hierarchical Mask System shows an example of how the PFSM engine utilizes instructions to execute the configured device state and sequence transitions of the mission state-machine. provides the instruction set and usage description of each instruction in the following sections. describes how the instructions are stored in the NVM memory.

REG_WRITE_VOUT_IMM Command Description: Write the target voltage of a specified regulator after a specified delay. This command is a spin-off of the REG_WRITE_IMM command with the intention to save instruction bits.

When included, the parameters can be in any order. Condition are listed in #GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/SLVSEA74920. Examples: GPIO1, BUCK1_PG, I2C_1 Type = LOW, HIGH, RISE, or FALL Timeout = timeout value in ns, µs, ms, or s. If no unit is entered, this field must be an integer value between 0-63. Timeout value is be rounded to the nearest achievable time based on the current step size. Current step size is based on the default NVM setting or a SET_DELAY value from a previous command in the same sequence. Assembler reports an error if the step size is too large or too small to meet the delay. Destination = Label to jump to if when timeout occurs. Destination must be after the WAIT statement in memory. Memory space can be either '0' or '1'. '0' indicates the destination address is in the PFSM memory space. '1' indicates the destination address is external and represents a FSM state ID. When using the jump command, the PFSM performs an unconditional jump. The command is be compiled as "WAIT COND=63 TYPE=LOW TIMEOUT=0 DEST=<Destination>". Condition 63 is a hardcoded 1, so the condition is never satisfied and hence always times out. Therefore this command always jumps to the destination. Examples: WAIT GPIO4 RISE 1 s <Destination> 0 — Wait to execute the command at the specified SRAM address when a rise edge is detected at GPIO4, or after 1 second WAIT COND=BUCK1_PG TYPE=HIGH TIMEOUT=500 µs DEST=<mcu2act_seq> — Wait to execute the commands at <mcu2act_seq> address as soon as BUCK1 output is within power-good range, or after 500 µs WAIT Command Conditions COND_SEL Condition Name COND_SEL Condition Name COND_SEL Condition Name COND_SEL Condition Name 0 GPIO1#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 16 LDO1_PG 32 I2C_0#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 48 LP_STANDBY_SEL 1 GPIO2#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 17 LDO2_PG 33 I2C_1#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 49 N/A 2 GPIO3#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 18 LDO3_PG 34 I2C_2#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 50 N/A 3 GPIO4#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 19 LDO4_PG 35 I2C_3#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 51 N/A 4 GPIO5#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 20 PGOOD 36 I2C_4#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 52 N/A 5 GPIO6#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 21 TWARN_EVENT 37 I2C_5#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 53 N/A 6 GPIO7 22 INTERRUPT_PIN 38 I2C_6#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 54 N/A 7 GPIO8 23 N/A 39 I2C_7#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 55 N/A 8 GPIO9 24 N/A 40 SREG0_0#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 56 N/A 9 GPIO10 25 N/A 41 SREG0_1#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 57 N/A 10 GPIO11 26 N/A 42 SREG0_2#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 58 N/A 11 BUCK1_PG 27 N/A 43 SREG0_3#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 59 N/A 12 BUCK2_PG 28 N/A 44 SREG0_4#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 60 N/A 13 BUCK3_PG 29 N/A 45 SREG0_5#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 61 N/A 14 BUCK4_PG 30 N/A 46 SREG0_6#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 62 0 15 BUCK5_PG(use for EXT_VMON PowerGood) 31 N/A 47 SREG0_7#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 63 1 Conditions GPIO1..GPIO6 are only processed if the associated GPIOx pins are configured as GPIO Conditions I2C0..7 refer to register bits TRIGGER_I2C_0..7, and are located in register FSM_I2C_TRIGGER Conditions SREG0_0...7 refer to bits 9...7 in PFSM storage register R0 DELAY_IMM Command Description: Delay the execution by a specified time Assembly command: DELAY_IMM <Delay> Delay = delay time in ns, µs, ms, or s. If no unit is entered, this field must be an integer value between 0-63. Delay value is be rounded to the nearest achievable time based on the current step size. Current step size is based on the default NVM setting or a SET_DELAY value from a previous command. Assembler reports an error if the step size is too large or too small to meet the delay. Examples: DELAY_IMM 100 µs — Delay execution by 100 µs DELAY_IMM 10 ms — Delay execution by 10 ms DELAY_IMM 8 — Delay execution by 8 ticks of the current PFSM time step DELAY_SREG Command Description: Delay the execution by a time value stored in the specified scratch register. The delay is calculated based on the curernt step size based on the value stored in PFSM_DELAY_STEP, or a SET_DELAY value from a previous command. Assembly command: DELAY_SREG <PFSM Storage Register> PFSM Storage Register can be R0, R1, R2, or R3. Examples: DELAY_SREG R0 — Delay execution by the time value stored in PFSM storage register R0 TRIG_SET Command Description: Set a trigger destination address for a given input signal or condition. These commands must be defined at the beginning of PFSM configuration memory. Assembly command: TRIG_SET [DEST=]<Destination> [ID=]<Trig_ID> [SEL=]<Trig_sel> [TYPE=]<Trig_type> [IMM=]<IMM> [EXT=]<Memory space> 'DEST=', 'ID=', 'SEL='. 'TYPE=', 'IMM=', and 'EXT=' are options. When included, the parameters can be in any order. Destination is the label where this trigger starts executing. Trig_ID is the ID of the hardware trigger module to be configured (value range 0-27). They must be defined in numeric order based on the priority of the trigger. Trig_Sel is the 'Trigger Name' from the . This 'Trigger Name' is the trigger signal to be associated with the specified TRIG_ID. Trig_type = LOW, HIGH, RISE, or FALL. IMM can be either '0' or '1'. = '0' if the trigger is not activated until the END command of a given task; '1' if the trigger is activated immediately and can abort a sequence. REENTRANT can be either '0' or '1'. '1' permits a trigger to return to the current state, that allows a self-branching trigger to execute the current sequence again. Memory space can be either '0' or '1'. '0' indicates the destination address is in the PFSM memory space. '1' indicates the destination address is external and represents a FSM state ID. Examples: TRIG_SET seq1 20 GPIO_1 LOW 0 0 — Set trigger 20 to be GPIO_1=Low, not immediate. When triggered, start executing at ‘seq1’ label. TRIG_SET DEST=seq2 ID=15 SEL=WD_ERROR TYPE=RISE IMM=0 EXT=0 — Set trigger 15 to be rising WD_ERROR trigger, not immediate. When triggered, start executing at ‘seq2’ label. TRIG_MASK Command Description: Sets a trigger mask that determines which triggers are active. Setting a ‘0’ enables the trigger, setting a ‘1’ disables (masks) the trigger. Assembly command: TRIG_MASK <Mask value> Mask Value = 28-bit mask in any literal integer format (decimal, hex, and so forth). Examples: TRIG_MASK 0x5FF82F0 — Set the trigger mask to 0x5FF82F0 END Command #GUID-829AAD39-C301-4ED7-A234-62018DE2CD53/X6385 shows the format of the END commands. END Command Format Bit[3:0] CMD 4 bits Description: Marks the final instruction in a sequential task Fields: CMD: Command opcode (0xC) Assembly command: END Configuration Memory Organization and Sequence Execution The configuration memory is loaded from NVM into an SRAM. shows an example configuration memory with only two configured sequences. Configuration Memory Script Example As soon as the PMIC state reaches the mission states, it starts reading from the configuration memory until it hits the first END command. Setting up the triggers (1-28) must be the first section of the configuration memory, as well as the first set of trigger configurations. The trigger configurations are read and mapped to an internal lookup table that contains the starting address associated with each trigger in the configuration memory. If the trigger destination is an FFSM state then the address contains the fixed state value. After the trigger configurations are read and mapped into the SRAM, these triggers control the execution flow of the state transitions. The signal source of each trigger is listed under . When a trigger or multiple triggers are activated, the PFSM execution engine looks up the starting address associated with the highest priority unmasked trigger, and starts executing commands until it hits an END command. The last commands before END statement is generally the TRIG_MASK command, which directs the PFSM to a new set of unmasked trigger configurations, and the trigger with the highest priority in the new set is serviced next. Trigger priority is determined by the Trigger ID associated with each trigger. The priority of the trigger decreases as the associated trigger ID increases. As a result, the critical error triggers are usually located at the lowest trigger IDs. The TRIG_SET commands specify if a trigger is immediate or non-immediate. Immediate triggers are serviced immediately, which involves branching from the current sequence of commands to reach a new target destination. The non-immediate triggers are accumulated and serviced in the order of priority through the execution of each given sequence until the END command in reached. Therefore, the trigger ID assignment for each trigger can be arranged to produce the desired PFSM behavior. The TRIG_MASK command determines which triggers are active at the end of each sequence, and is usually placed just before the END instruction. The TRIG_MASK takes a 28-bit input to allow any combination of triggers to be enabled with a single command. Through the definition of the active triggers after each sequence execution the TRIG_MASK command can be conceptualized as establishing a power state. The above sequence of waiting for triggers and executing the sequence associated with an activated trigger is the normal operating condition of the PFSM execution engine when the PMIC is in the MISSION state. The fixed device power FSM takes over control from the execution engine each time an event occurs that requires a transition from the MISSION state of the PMIC to a fixed device state.

The is used as an example state machine that is defined through the configuration memory using the configuration FSM instructions. Example of a Mission State-Machine Each power state (light blue bubbles in ) defines the ON or OFF state and the sequencing timing of the external regulators and GPIO outputs. This example defines four power states: STANDBY, ACTIVE, MCU ONLY, and DEEP_SLEEP/S2R three power states: STANDBY, ACTIVE and RETENTION states. The priority order of these states is as follows: ACTIVE MCU ONLY DEEP SLEEP/S2R STANDBY The transitions between each power state is determined by the trigger signals source pre-selected from . These triggers are then placed in the order of priority through the trigger ID assignment of each trigger source. The critical error triggers are placed first, some specified as immediate triggers that can interrupt an on-going sequence. The non-error triggers, which are used to enable state transitions during normal device operation, are then placed according to the priority order of the state the device is transitioning to. list the trigger signal sources, in the order of priority, used to define the power states and transitions of the example mission state machine shown in . This table also helps to determine which triggers must be masked by the TRIG_MASK command upon arriving a pre-defined power state to produce the desired PFSM behavior.

When an error occurs, which requires the device to enter directly to the SAFE RECOVERY state, the mask for this trigger must be removed while all other non-immediate triggers are masked. The device exits the mission states and the FFSM state machine takes over control of the device power states once this trigger is executed. Pre-Configured Hardware Transitions There are some pre-defined trigger sources, such as on-requests and off-requests, that are constructed with the combination of hardware input signals and register bits settings. This section provides more detail to these pre-defined trigger sources and shows how they can be utilized in the PFSM configuration to initiate state to state transitions. ON Requests ON requests are used to switch on the device, which then transitions the device from the STANDBY or the LP_STANDBY to the state specified by STARTUP_DEST[1:0]. After the device arrives at the corresponding STARTUP_DEST[1:0] operation state, the MCU must setup the SLEEP1 and NSLEEP2 signals accordingly before clearing the STARTUP_INT interrupt. Once the interrupt is cleared, the device stays or moves to the next state corresponding to the NSLEEP signals state assignment as specified in . #GUID-CF09F512-F01B-4591-9EAD-EE716C2976A4/SLVSEA76972 lists the available ON requests.

When this pin is configured as the nPWRON button, a short button press detection is latched internally as a device enable signal until the NPWRON_START_INT is cleared, or a long press key event is detected. The short button press detection occurs when an falling edge is detected at the nPWRON pin. When the NPWRON_START_MASK bit is set to '1', the device does no longer react to the changing state of the pin as the nPWRON press button. The nPWRON/ENABLE pin is a level sensitive pin when it is configured as an ENABLE pin, and an assertion enables the device until the pin is released. When the ENABLE_MASK bit is set to '1', the device does no longer react to the changing state of the pin as the ENABLE switch. OFF Requests An OFF request is used to orderly switch off the device. OFF requests initiate transition from any other mission state to the STANDBY state or the LP_STANDBY state depending on the setting of the LP_STANDBY_SEL bit. #GUID-117B0898-2FEC-4E9D-9F33-06019819BC63/SLVSEA7991 lists the conditions to generate the OFF requests and the corresponding destination state.

When the nPWRON or ENABLE pin is used as the OFF request, the device wakes up from the STANDBY or the LP_STANDBY state through the ON request initiated by the same pin. The NPWRON_START_MASK or the ENABLE_MASK must remain low in this case to allow the detection of the ON request initiated by the pin. If the device needs to enter the LP_STANDBY state through the OFF request, it is important that the state of the nPWRON or ENABLE pin must remain the same until the state transition is completed. Failure to do so may result in unsuccessful wake-up from the LP_STANDBY state when the pin re-initiates On request. Using the I2C_TRIGGER_0 bit as the OFF request enables the device to wake up from the STANDBY or the LP_STANDBY states through the detection of LP_WKUPn/WKUPn pins, as well as RTC alarm or timer interrupts. To enable this feature, the device must set the I2C_TRIGGER_0 bit to '1' while the NSLEEPn signals are masked, and the ON request (initialized by the nPWRON or ENABLE pins) must remain active. Also the interrupt bits ENABLE_INT, FSD_INT and the GPIOx_INT bits (for the GPIOx pins assigned as WKUP1 or WKUP2) must be cleared before setting the I2C_TRIGGER_0 bit to '1'. NSLEEP1 and NSLEEP2 Functions The SLEEP requests are activated through the assertion of nSLEEP1 or nSLEEP2 pins that are the secondary functions of the 11 GPIO pins. These pins can be selected through GPIO configuration using the GPIOx_SEL register bits. If the nSLEEP1 or nSLEEP2 pins are not available, the NSLEEP1B and NSLEEP2B register bits can be configured in place for their functions. The input of nSLEEP1 pin and the state of the NSLEEP1B register bit are combined to create the NSLEEP1 signal through an OR function. Similarly for the input of the nSLEEP2 pin and the NSLEEP2B register bit as they are combined to create the NSLEEP2 signal. A 1 → 0 logic level transition of the NSLEEP signal generates a sleep request, while a 0 → 1 logic level transition reverses the sleep request in the example PFSM from . When a NSLEEPn signal transitions from 1 → 0, it generates a sleep request to go from a higher power state to a lower power state. When the signal transitions from 0 → 1, it reverses the sleep request and returns the device to the higher power state. The NSLEEP1 signal is designed to control the SoC supply rails. The NSLEEP2 signal is designed to control the MCU supply rails. When NSLEEP1 signal changes from 1 → 0, depending on the state of NSLEEP2, the TPS6593-Q1 device exits ACTIVE state and enters either the MCU ONLY or the S2R states. When NSLEEP2 signal changes from 1 → 0, the device enters the S2R state regardless the state of NSLEEP1. When the NSLEEP2 input signal changes from 0 →1, the MCU supply rails are enabled and the device exits S2R state. Depending on the state of NSLEEP1 signal, the device enters either the MCU ONLY or the ACTIVE state. In order for the system to function correctly, the MCU rails must be enabled when the NSLEEP1 input signal changes from 0 →1, which enables the SOC supply rails. NSLEEP1 0 →1 transition is ignored if NSLEEP2 is 0. The NSLEEPn_MASK bit can be used to mask the sleep request associated with the corresponding NSLEEPn signal. When the NSLEEPn_MASK = 1, the corresponding NSLEEPn signal is ignored. shows how the combination of the NSLEEPn signals and NSLEEPn_MASK bits creates triggers A/B/C/D to the FSM to control the power state of the device. The states of the resources during ACTIVE, SLEEP, and DEEP SLEEP/S2R states are defined in the LDOn_CTRL and BUCKn_CTRL registers. For each resource, a transition to the MCU ONLY or the DEEP SLEEP/S2R states is controlled by the FSM when the resource is associated to the SLEEP or DEEP SLEEP/S2R states. shows the corresponding state assignment based on the state of the NSLEEPn and their corresponding mask signals using the example PFSM from .

Any one of these GPIO pins when configured as an input pin can be configured to wake up the device by setting GPIOn_SEL bit to select the WKUP1 or WKUP2 functions. In the example PFSM depicted in , when a GPIO pin is configured as a WKUP1 pin, a rising or falling edge detected at the input of this pin (configurable by the GPIOn_FALL_MASK and the GPIOn_RISE_MASK bits) wakes up the device to the ACTIVE state. Likewise if a GPIO pin is configured as a WKUP2 pin, a detected edge wakes up the device to the MCU ONLY state. If multiple edge detections of WKUP signals occur simultaneous, the device goes to the state in the following priority order: ACTIVE MCU ONLY When a valid edge is detected at a WKUP pin, the nINT pin generates an interrupt to signal the MCU of the wake-up event, and the GPIOx_INT interrupt bit is set. The wake request remains active until the GPIOx_INT bit is cleared by the MCU. While the wake request is executing, the device does not react to sleep requests to enter a lower power state until the corresponding GPIOx_INT interrupt bit is cleared to cancel the wake request. After the wake request is canceled, the device returns to the state indicated by the NSLEEP1 and NSLEEP2 signals as shown in . LP_WKUP Pins for Waking Up from LP STANDBY The LP_WKUP functions are activated through the edge detection of LP_WKUP pins, configurable as secondary functions of GPIO3 and GPIO4. They are specially designed to wake the device up from the LP STANDBY state when a high speed wake-up signal is detected. Similar to the WKUP1 and WKUP2 pins, when GPIO3 or GPIO4 pin is configured as an LP_WKUP1 pin, a rising or falling edge detected at the input of this pin (configurable by the GPIOn_FALL_MASK and the GPIOn_RISE_MASK bits) wakes up the device to the ACTIVE state. Likewise, if the pin is configured as an LP_WKUP2 pin, a detected edge wakes up the device to the MCU ONLY state. If multiple edge detections of LP_WKUP signals occur simultaneously, the device goes to the state in the following priority order: ACTIVE MCU ONLY Due to a digital control erratum in the device, the ENABLE_MASK/NPWRON_START_MASK bit must be set to '1' before the device enters LP_STANDBY state in order for the LP_WKUP2 pin to correctly wake up the device to the MCU_ONLY state. The TPS6593-Q1 device supports limited CAN wake-up capability through the LP_WKUP1/2 pins. When an input signal (without deglitch) with logic level transition from high-to-low or low-to-high with a minimum pulse width of tWK_PW_MIN is detected on the assigned LP_WKUP1/2 pins, the device wakes up asynchronously and executes the power up sequence. CAN-transceiver RXD- or INH-outputs can be connected to the LP_WKUP pin. If RXD-output is used, it is assumed that the transceiver RXD-pin IO is powered by the transceiver itself from an external supply when TPS6593-Q1 is in the LP_STANDBY state. If INH-signal is used it has to be scaled down to the recommenced GPIO input voltage level specified in the electrical characteristics table. In this PFSM example, the device can wake up from the LP_STANDBY state through the detection of LP_WKUP pins only if it enters the LP_STANDBY state through the TRIGGER_I2C_0 OFF request while the NSLEEPn signals are masked, and the on request initialized by the nPWRON/ENABLE pin remains active. Once a valid wake-up signal is detected at the LP_WKUP pin, it is handled as a WAKE request. The nINT pin generates an interrupt to signal the MCU of the wake-up event, and the corresponding GPIOx_INT interrupt bit is set. The wake request remains active until the interrupt bit is cleared by the MCU. shows how the device returns to the state indicated by the NSLEEP1 and NSLEEP2 signals after the wake request is canceled. illustrates the valid wake-up signal at the LP_WKUP1/2 pins, and the generation and clearing of the internal wake-up signal. CAN Wake-Up Timing Diagram Error Handling Operations The FSM engine of the TPS6593-Q1 device is designed to handle the following types of errors throughout the operation: Power Rail Output Error Boot BIST Error Runtime BIST Error Catastrophic Error Watchdog Error Error Signal Monitor (ESM) Error Warnings Power Rail Output Error A power rail output error occurs when an error condition is detected on the output rails of the device that are used to power the attached MCU or SoC. These errors include the following: Rails not reaching or maintaining within the power good voltage level threshold. A short condition that is detected at a regulator output. The load current that exceeds the forward current limit. The BUCKx_GRP_SEL, LDOn_GRP_SEL and VCCA_GRP_SEL registers are used to configure the rail group for all of the Bucks, LDOs, and the voltage monitors that are available for external rails. The selectable rail groups are MCU rail group, SoC rail group, or OTHER rail group. The TPS6593-Q1 device is designed to react differently when an error is detected from a power resource assigned to the different rail groups. shows how the SOC_RAIL_TRIG[1:0], MCU_RAIL_TRIG[1:0], and OTHER_RAIL_TRIG[1:0] register bits are used as the Immediate Shutdown Trigger Mask, Orderly Shutdown Trigger Mask, MCU Power Error Trigger Mask, or the SoC Power Error Trigger Mask. The settings of these register bits determine the error handling sequence that the assigned groups of rails perform in case of an output error. The PFSM engine can be configured to execute the appropriate error handling sequence for the following error handling sequence options: immediate shutdown, orderly shutdown, MCU power error, or SOC power error. For example, if an immediate shutdown sequence is assigned to the MCU rail group through the MCU_RAIL_TRIG[1:0] register bits, any failure detected in this group of rails causes the IMMEDIATE_SHUTDOWN trigger to be executed. This trigger is expected to start the immediate shutdown sequence and cause the device to enter the SAFE RECOVERY state. The device immediately resets the attached MCU and SoC by driving the nRSTOUT and nRSTOUT_SoC (GPO1 or GPIO11) pins low. All of the power resources assigned to the MCU and SOC shut down immediately without a sequencing order. The nINT pin signals that an MCU_PWR_ERR_INT interrupt event has occurred and the EN_DRV pin is forced low. If the error is recoverable within the recovery time interval, the device increments the recovery count, returns to INIT state, and reattempts the power up sequence (if the recovery count has not exceeded the counter threshold). If the recovery count has already exceeded the threshold, the device stays in the SAFE RECOVERY state until VCCA voltage is below the VCCA_UVLO threshold and the device is power-cycled. The power resources assigned to the SoC rail group are typically assigned to the SOC power error handling sequence. In this PFSM example depicted in , when a power resource in this group is detected, the PFSM typically causes the device to execute the shutdown of all the resources assigned to the SoC rail group, and the device enters the MCU ONLY state. The device immediately resets the attached SoC by toggling the nRSTOUT_SoC (GPO1 or GPIO11) pin. The reset output to the MCU and the resources assigned to the MCU rail group remain unchanged. The EN_DRV pin also remains unchanged, and the nINT pin signals that an SOC_PWR_ERR_INT interrupt event has occurred. To recover from the MCU_ONLY state after a SOC power error, the MCU software must set NSLEEP1 signal to '0' while NSLEEP2 signal remains '1'. This action signals TPS6593-Q1 that MCU has acknowledged the SOC power error, and is ready to return to normal operation. MCU can then set the NSLEEP1 signal back to '1' for the device to return to ACTIVE state and reattempt the SoC power up. Refer to for information regarding the setting of the NSLEEP1 and NSLEEP2 signals. The power resources used for peripheral devices in the system, for which no error-handling action is required, the rail mapping needs to be selected as "no group assigned". Catastrophic Error Catastrophic errors are errors that affect multiple power resources such as errors detected in supply voltage, LDOVINT supply for control logic, errors on internal clock signals, device temperature passing the thermal shutdown threshold, error detected on the SPMI bus, or an error detected in the PFSM sequence. Following errors are grouped as severe errors: VCCA > OVP threshold Junction temperature > immediate shutdown level Error in PFSM Sequence For these above listed errors, depending on the setting of bits SEVERE_ERR_TRIG[1:0], an immediate or orderly shutdown condition is created. The PFSM executes the corresponding sequence for the IMMEDIATE_SHUTDOWN trigger or the ORDERLY_SHUTDOWN trigger and enters the SAFE RECOVERY state. Following errors are grouped as moderate errors: Junction temperature > orderly shutdown level BIST failure CRC error in register map Recovery counter exceeding the threshold value Error on SPMI bus Readback error on nRSTOUT pin or nINT pin For these above listed errors, depending on the setting of bits MODERATE_ERR_TRIG[1:0], an immediate or orderly shutdown condition is created. The PFSM executes the corresponding sequence for the IMMEDIATE_SHUTDOWN trigger or the ORDERLY_SHUTDOWN trigger and enters the SAFE RECOVERY state. For following errors, the device performs an immediate shutdown and resets all internal logic circuits: VCCA < UVLO threshold Error on LDOVINT supply Errors on internal clock signals Unrecoverable CRC error in the SRAM memory of the PFSM For all of the above listed errors, the device resets the attached MCU and SoC by driving the nRSTOUT and the GPIO pin used as nRSTOUT_SoC (GPO1 or GPIO11) pins low. All of the power resources assigned to the attached MCUand SOC are shut down. The nINT pin is driven low to signal an interrupt event has occurred, and the EN_DRV pin is forced low. Watchdog (WDOG) Error Watchdog (WDOG) describes details about the Watchdog (WDOG) errors detection mechanisms. Warnings Warning are non-catastrophic errors. When such an error occurs while the device is in the operating states, the device detects the error and handles the error through the interrupt handler. These are errors such as thermal warnings, I2C, or SPI communication errors, or power resource current limit detection while the output voltage still maintains within the power good threshold. When these errors occur, the nINT pin is driven low to signal an interrupt event has occurred. The device remains in the operation state and the state of the EN_DRV pin, the power resources, and the reset outputs remain unchanged. The power resource current limit detection can, by setting bit EN_ILIM_FSM_CTRL=1, be configured such that it is handled as a Power Rail Output Error as described in . Device Start-up Timing shows the timing diagram of the TPS6593-Q1 after the first supply detection. Device Start-up Timing Diagram tINIT_REFCLK_LDO is the start-up time for the reference block. tINIT_NVM_ANALOG is the time for the device to load the default values of the NVM configurable registers from the NVM memory, and the start-up time for the analog circuits in the device. tINIT_REFCLK_LDO and tINIT_NVM_ANALOG are defined in the electrical characteristics table. BOOT_BIST is the sum of tLBISTrun (which is defined in the electrical characterization tables) and a less than 60us time-interval needed for the cyclic redundancy check on the register map and the SRAM. The Power Sequence time is the total time for the device to complete the power up sequence. Please refer to for more details. The reset delay time is a configurable wait time for the nRSTOUT and the nRSTOUT_SoC release after the power up sequence is completed. Power Sequences A power sequence is an automatic preconfigured sequence the TPS6593-Q1 device applies to its resources, which include the states of the BUCKs, LDOs, 32-kHz clock and the GPIO output signals. For a detailed description of the GPIOs signals, please refer to General-Purpose I/Os (GPIO Pins). shows an example of a power up transition followed by a power down transition. The power up sequence is triggered through a valid on request, and the power down sequence is trigger by a valid off request. The resources controlled (for this example) are: BUCK3, LDO1, BUCK2, LDO2, GPIO1 , LDO4, and LDO3. The time between each resource enable and disable (TinstX) is also part of the preconfigured sequence definition. A resource not assigned to any power sequence remains in off mode during the power-up sequence. The attached MCU or SoC can enable and configure this resource independently when the power-up sequence completes. Also the EN_DRV remains low during the power-up sequence. The attached MCU or SoC can release the EN_DRV pin by setting the ENABLE_DRV bit (requires running watchdog, ESM started and no pending interrupt bits). Power Sequence Example As the power sequences of the TPS6593-Q1 device are defined according to the processor requirements, the total time for the completion of the power sequence varies across various system definitions. First Supply Detection The TPS6593-Q1 device can be configured to automatically start up from a first supply-detection (FSD) event detection. This feature is enabled by setting the FSD_MASK register bit to '0', and setting the NPWRON_SEL[1:0] registers bits to '10' or '11' to mask the functionality of the nPWRON/ENABLE pin. When the device is powered up from the NO SUPPLY state, the FSD detection is validated after the NVM default for this feature is loaded into the device memory. When the FSD feature is enabled, the PMIC immediately powers up from the NO SUPPLY state to an operation state, configured by the STARTUP_DEST[1:0] bits when VCCA > VCCA_UV, while VCCA_UV gating is performed, and only when VCCA voltage monitoring is enabled (VCCA_VMON_EN = 1). After the device arrives the corresponding STARTUP_DEST[1:0] operation state, the MCU must setup the NSLEEP1 and NSLEEP2 signals accordingly before clearing the FSD_INT interrupt. Once the interrupt is cleared, the device either stays in the current state or moves to the destination state according to the state of the NSLEEP1 and NSLEEP2 signals as specified in . Register Power Domains and Reset Levels The TPS6593-Q1 registers are defined by the following categories: LDOVINT registers LDOVRTC registers (registers in RTC domain) LDOVINT registers The LDOVINT registers are powered by the internal LDOVINT, and retain their values until the device enters the LP_STANDBY state or the BACKUP state after the device was fully powered up and in operation. When this occurs, LDOVINT is powered off, all LDOVINT registers (including the VSET registers which store the output voltage levels for all of the external power rails) are reset. As the device re-enters the INIT state from a wake up signal or an On-request, the registers powered by the LDOVINT are re-written with the default values from NVM (Non-Volatile Memory). All registers in the device, except the LDOVRTC registers (registers in RTC domain), are powered by LDOVINT. LDOVRTC registers (registers in RTC domain) The LDOVRTC registers (registers in RTC domain) retain their values until a Power-On-Reset (POR) occurs. POR occurs when the device loses supply power and enters the NO SUPPLY state. When this occurs, LDOVRTC is powered off, and all LDOVRTC registers are reset. Following are the LDOVRTC registers: All RTC registers RTC and Crystal Oscillator bits Status registers for the following events: TSD and RTC reset Control registers for PWRON/ENABLE, GPIO3, and GPIO4 pins (for wake signal monitor during LP_STANDBY state) Following interrupt registers: FSD_INT RECOV_CNT_INT TSD_ORD_INT TSD_IMM_INT PFSM_ERR_INT VCCA_OVP_INT ESM_MCU_RST_INT ESM_SOC_RST_INT WD_RST_INT WD_LONGWIN_TIMEOUT_INT NPWRON_LONG_INT Device State Machine The TPS6593-Q1 device integrates a finite state machine (FSM) engine that manages the state of the device during operating state transitions. The device supports NVM-configurable mission states with configurable input triggers for transitions between states. Any resources, including the 5 BUCK regulators, 4 LDO regulators, and all of the digital IO pins including the 11 GPIO pins on the device can be controlled during power sequencing. When a resource is not controlled or configured through a power sequence, the resource is left in the default state as pre-configured by the NVM. Each resource can be pre-configured through the NVM configuration, or re-configured through register bits. Therefore, the user can statically control the resource through the control interfaces (I2C or SPI), or the FSM can automatically control the resource during state sequences. The FSM is powered by an internal LDO that is automatically enabled when VCCA supply is available to the device. Ensuring that the VCCA supply is the first supply available to the device is important to ensure proper operation of all the power resources as well as the control interface and device IOs. There are three parts of the FSM that control the operational modes of the TPS6593-Q1 device: Fixed Device Power Finite State Machine (FFSM) Pre-configurable Finite State Machine (PFSM) for Mission States (ACTIVE, MCU_ONLY, S2R, DEEP_SLEEP) Error Handling Operations The PFSM provides configurable rail and voltage monitoring sequencing utilizing instructions in configuration memory.

While the device is in one of the Hardware Device Powers states, the ENABLE_DRV bit remains low. The definitions and transition triggers of the Device Power States are fixed and cannot be reconfigured. Following are the definitions of the Device Power states: NO SUPPLY The device is not powered by a valid energy source on the system power rail. The device is completely powered off. BACKUP (RTC backup battery) The device is not powered by a valid supply on the system power rail (VCCA < VCCA_UVLO); a backup power source, however, is present and is within the operating range of the LDOVRTC. The RTC clock counter remains active in this state if it has been previously activated by appropriate register enable bit. The calendar function of the RTC block is activated, but not accessible in this state. Customer has the option to enable the shelf mode by disconnecting the VCCA supply completely, even while the backup battery is connected to the VBACKUP pin. The shelf mode forces the device to skip the BACKUP state and enters the NO SUPPLY state under VCCA_UVLO condition to reduce current draining from the backup battery. LP_STANDBY The device can enter this state from a mission state after receiving a valid OFF request or an I2C trigger, and the LP_STANDBY_SEL= 1. When the device is in this state, the RTC clock counter and the RTC Alarm or Timer Wake-up functions are active if they have been previously activated by appropriate register enable bit. Low Power Wake-up input monitor in the LDOVRTC domain (LP_WKUP secondary function through GPIO3 or GPIO4) and the on request monitors are also enabled in this state. When a logic level transition from high-to-low or low-to-high with a minimum pulse length of tLP_WKUP is detected on the assigned LP_WKUP pin, or if the device detects a valid on-request or a wake-up signal from the RTC block, the device proceeds to power up the device and reach the default mission state. More details regarding the LP_WAKE function can be found in . INIT The device is powered by a valid supply on the system power rail (VCCA ≥ VCCA_UV). If the device was previously in LP_STANDBY state, it has received an external wake-up signal at the LP_WKUP1/2 pins, the RTC alarm or timer wake-up signal, or an On Request from the nPWRON/ENABLE pin. Device digital and monitor circuits are powered up. The PMIC reads its internal NVM memory in this state and configures default values to registers, IO configuration and FSM accordingly. BOOT BIST The device is running the built-in self-test routine that includesThe ABIST on the voltage monitor circuits for the BUCK regulators, the LDO regulators is performed after the start-up of these regulators. The ABIST on the VMON1 and VMON2 is performed after these voltage monitors are enabled. See Voltage Monitors. An option is available to shorten the device power up time from the NO_SUPPLY state by setting the NVM bit FAST_BOOT_BIST = '1' to skip the LBIST. Software can also set the FAST_BIST = '1' to skip LBIST after the device wakes up from the LP STANDBY state. When the device arrives at this state from the SAFE_RECOVERY state, LBIST is automatically skipped if it has not previously failed. If LBIST failed, but passed after multiple re-tries before exceeding the recovery counter limit, the device powers up normally. The following NVM bits are pre-configured options to enable or disable parts of the CRC tests if further sequence time reduction is required (please refer to the user's guide of the orderable part number): REG_CRC_EN = '0': disables the register map and SRAM CRC check Note: the BIST tests are executed as parallel processes, and the longest process determines the total BIST duration the ABIST on the voltage monitor circuits of the BUCKx regulator, LDOn regulators, VMON1 and VMON2 is performed individually after these voltage monitors are enabled. See Voltage Monitors) RUNTIME BIST A request was received from the MCU to exercise a run-time built-in self-test (RUNTIME_BIST) on the device. No rails are modified and all external signals, including all I2C or SPI interface communications, are ignored during the RUNTIME_ BIST. During the RUNTIME_BIST, the device performs the same self-test routines as listed for the BOOT_BIST state. Furthermore, during RUNTIME_BIST the device performs the ABIST routine on all enabled voltage monitor circuits. If the device passed BIST, it resumes the previous operation. If the device failed BIST, it shuts down all of the regulator outputs and proceed to the SAFE RECOVERY state. In order to avoid a register CRC error, all register writes must be avoided after the request for the BIST operation until the device pulls the nINT pin low to indicate the completion of BIST. The results of the RUNTIME_BIST are indicated by the BIST_PASS_INT or the BIST_FAIL_INT interrupt bits.After completion of the RUNTIME_BIST, the LDOx_UV detections are masked for a time-interval equal to the configured LDOx ramp-up time (25 mV/μs or 3 mV/μs according configuration bit LDOx_SLOW_RAMP). The actual LDOx output voltages are not affected by this masking of the LDOx_UV detections. SAFE RECOVERY The device meets the qualified error condition for immediate or ordered shutdown request. If the error is recovered within the recovery time interval or meets the restart condition, the device increments the recovery counter, and returns to INIT state if the recovery counter value does not exceed the threshold value. Until a supply power cycle occurs, the device stays in the SAFE RECOVERY state if one of the following conditions occur: the recovery counter exceeds the threshold value the die temperature cannot be reduced to less than TWARN level VCCA stays above OVP threshold When multiple system conditions occur simultaneously that demand power state arbitration, the device goes to the higher priority state according to the following priority order: NO SUPPLY BACKUP SAFE_RECOVERY LP_STANDBY MISSION STATES shows the power transition states of the FSM engine. State Diagram for Device Power States Register Resets and NVM Read at INIT State Several registers inside the TPS6593-Q1 have pre-configured default values that are stored in the NVM of the TPS6593-Q1. These registers are referred to as NVM pre-configured registers. When the device transitions from the LP_STANDBY or the SAFE_RECOVERY to the INIT state, based on FIRST_STARTUP_DONE bit, the registers are reset and the NVM is read. When the FIRST_STARTUP_DONE is '0', registers which are not in the RTC domain are reset, and all of the NVM pre-configured registers including the ones in the RTC domain, are loaded from the NVM. When the FIRST_STARTUP_DONE bit is set to '1', typically after the initial power up from a supply power cycle, the registers in the RTC domain are not reset, and the NVM pre-configured registers in the RTC domain are not re-loaded from the NVM. Setting the FIRST_STARTUP_DONE bit prevents the control and status bits stored in the RTC domain registers from being over written. Register resets and NVM read at INIT state FIRST _STARTUP_DONE NVM pre-configured registers in RTC Domain Registers without NVM pre-configuration in RTC Domain Other NVM pre-configured registers Registers without NVM pre-configuration 0 Defaults read from NVM No changes Reset and defaults read from NVM Reset 1 No changes No changes Reset and defaults read from NVM Reset Below are the NVM pre-configured register bits in the RTC domain: GPIO3_CONF and GPIO4_CONF registers, except the GPIOn_DEGLITCH_EN bits GPIO3_RISE_MASK, GPIO3_FALL_MASK, GPIO4_RISE_MASK, and GPIO4_FALL_MASK bits NPWRON_CONF register except ENALBE_DEGLITCH_EN and NRSTOUT_OD bits FSD_MASK, ENABLE_MASK, NPWRON, START_MASK, and NPWRON_LONG_MASK bits STARTUP_DEST, FAST_BIST, LP_STANDBY_SEL, XTAL_SEL, and XTAL_EN bits PFSM_DELAYn, and RTC_SPARE_n bits Below are the register bits without NVM pre-configuration in the RTC domain: FIRST_STARTUP_DONE bit SCRATCH_PAD_n bits All of RTC control and configuration registers Fixed Device Power FSM The Fixed Device Power portion of the FSM engine manages the power up of the device before the power rails are fully enabled and ready to power external loadings, and the power down of the device when in the event of insufficient power supply or device or system error conditions. While the device is in one of the Hardware Device Powers states, the ENABLE_DRV bit remains low. The definitions and transition triggers of the Device Power States are fixed and cannot be reconfigured. Following are the definitions of the Device Power states: NO SUPPLY The device is not powered by a valid energy source on the system power rail. The device is completely powered off. BACKUP (RTC backup battery) The device is not powered by a valid supply on the system power rail (VCCA < VCCA_UVLO); a backup power source, however, is present and is within the operating range of the LDOVRTC. The RTC clock counter remains active in this state if it has been previously activated by appropriate register enable bit. The calendar function of the RTC block is activated, but not accessible in this state. Customer has the option to enable the shelf mode by disconnecting the VCCA supply completely, even while the backup battery is connected to the VBACKUP pin. The shelf mode forces the device to skip the BACKUP state and enters the NO SUPPLY state under VCCA_UVLO condition to reduce current draining from the backup battery. LP_STANDBY The device can enter this state from a mission state after receiving a valid OFF request or an I2C trigger, and the LP_STANDBY_SEL= 1. When the device is in this state, the RTC clock counter and the RTC Alarm or Timer Wake-up functions are active if they have been previously activated by appropriate register enable bit. Low Power Wake-up input monitor in the LDOVRTC domain (LP_WKUP secondary function through GPIO3 or GPIO4) and the on request monitors are also enabled in this state. When a logic level transition from high-to-low or low-to-high with a minimum pulse length of tLP_WKUP is detected on the assigned LP_WKUP pin, or if the device detects a valid on-request or a wake-up signal from the RTC block, the device proceeds to power up the device and reach the default mission state. More details regarding the LP_WAKE function can be found in . INIT The device is powered by a valid supply on the system power rail (VCCA ≥ VCCA_UV). If the device was previously in LP_STANDBY state, it has received an external wake-up signal at the LP_WKUP1/2 pins, the RTC alarm or timer wake-up signal, or an On Request from the nPWRON/ENABLE pin. Device digital and monitor circuits are powered up. The PMIC reads its internal NVM memory in this state and configures default values to registers, IO configuration and FSM accordingly. BOOT BIST The device is running the built-in self-test routine that includesThe ABIST on the voltage monitor circuits for the BUCK regulators, the LDO regulators is performed after the start-up of these regulators. The ABIST on the VMON1 and VMON2 is performed after these voltage monitors are enabled. See Voltage Monitors. An option is available to shorten the device power up time from the NO_SUPPLY state by setting the NVM bit FAST_BOOT_BIST = '1' to skip the LBIST. Software can also set the FAST_BIST = '1' to skip LBIST after the device wakes up from the LP STANDBY state. When the device arrives at this state from the SAFE_RECOVERY state, LBIST is automatically skipped if it has not previously failed. If LBIST failed, but passed after multiple re-tries before exceeding the recovery counter limit, the device powers up normally. The following NVM bits are pre-configured options to enable or disable parts of the CRC tests if further sequence time reduction is required (please refer to the user's guide of the orderable part number): REG_CRC_EN = '0': disables the register map and SRAM CRC check Note: the BIST tests are executed as parallel processes, and the longest process determines the total BIST duration the ABIST on the voltage monitor circuits of the BUCKx regulator, LDOn regulators, VMON1 and VMON2 is performed individually after these voltage monitors are enabled. See Voltage Monitors) RUNTIME BIST A request was received from the MCU to exercise a run-time built-in self-test (RUNTIME_BIST) on the device. No rails are modified and all external signals, including all I2C or SPI interface communications, are ignored during the RUNTIME_ BIST. During the RUNTIME_BIST, the device performs the same self-test routines as listed for the BOOT_BIST state. Furthermore, during RUNTIME_BIST the device performs the ABIST routine on all enabled voltage monitor circuits. If the device passed BIST, it resumes the previous operation. If the device failed BIST, it shuts down all of the regulator outputs and proceed to the SAFE RECOVERY state. In order to avoid a register CRC error, all register writes must be avoided after the request for the BIST operation until the device pulls the nINT pin low to indicate the completion of BIST. The results of the RUNTIME_BIST are indicated by the BIST_PASS_INT or the BIST_FAIL_INT interrupt bits.After completion of the RUNTIME_BIST, the LDOx_UV detections are masked for a time-interval equal to the configured LDOx ramp-up time (25 mV/μs or 3 mV/μs according configuration bit LDOx_SLOW_RAMP).

An option is available to shorten the device power up time from the NO_SUPPLY state by setting the NVM bit FAST_BOOT_BIST = '1' to skip the LBIST. Software can also set the FAST_BIST = '1' to skip LBIST after the device wakes up from the LP STANDBY state. When the device arrives at this state from the SAFE_RECOVERY state, LBIST is automatically skipped if it has not previously failed. If LBIST failed, but passed after multiple re-tries before exceeding the recovery counter limit, the device powers up normally. The following NVM bits are pre-configured options to enable or disable parts of the CRC tests if further sequence time reduction is required (please refer to the user's guide of the orderable part number): REG_CRC_EN = '0': disables the register map and SRAM CRC check Note: the BIST tests are executed as parallel processes, and the longest process determines the total BIST duration the ABIST on the voltage monitor circuits of the BUCKx regulator, LDOn regulators, VMON1 and VMON2 is performed individually after these voltage monitors are enabled.

No rails are modified and all external signals, including all I2C or SPI interface communications, are ignored during the RUNTIME_ BIST. During the RUNTIME_BIST, the device performs the same self-test routines as listed for the BOOT_BIST state. Furthermore, during RUNTIME_BIST the device performs the ABIST routine on all enabled voltage monitor circuits. If the device passed BIST, it resumes the previous operation. If the device failed BIST, it shuts down all of the regulator outputs and proceed to the SAFE RECOVERY state. In order to avoid a register CRC error, all register writes must be avoided after the request for the BIST operation until the device pulls the nINT pin low to indicate the completion of BIST. The results of the RUNTIME_BIST are indicated by the BIST_PASS_INT or the BIST_FAIL_INT interrupt bits.After completion of the RUNTIME_BIST, the LDOx_UV detections are masked for a time-interval equal to the configured LDOx ramp-up time (25 mV/μs or 3 mV/μs according configuration bit LDOx_SLOW_RAMP). The actual LDOx output voltages are not affected by this masking of the LDOx_UV detections.

The configuration memory allows configurations of the triggers and the operation states that together form the configurable sub state machine within the scope of mission states. This sub state machine can be used to control and sequence the different voltage outputs as well as any GPIO outputs that can be used as enable for external rails. When the device is in a mission state, it has the capacity to supply the processor and other platform modules depending on the power rail configuration. The definitions and transition triggers of the mission states are configurable through the NVM configuration. Unlike the user registers, the PFSM definition stored in the NVM cannot be modified during normal operation. When the PMIC determines that a transition to another operation state is necessary, it reads the configuration memory to determine what sequencing is needed for the state transition. Furthermore, the PFSM has four storage registers, further referred to as PFSM storage registers (R0-3). shows how the trigger signals for each state transition can come from a variety of interface or GPIO inputs, or potential error sources. shows how the device processes all of the possible error sources inside the PFSM engine, a hierarchical mask system is applied to filter out the common errors that can be handled by interrupt only, and categorize the other error sources as Severe Global Error, Moderate Global Error, and so forth. The filtered and categorized triggers are sent into the PFSM engine, that then determines the entry and exit condition for each configured mission state. Error Source Hierarchical Mask System shows an example of how the PFSM engine utilizes instructions to execute the configured device state and sequence transitions of the mission state-machine. provides the instruction set and usage description of each instruction in the following sections. describes how the instructions are stored in the NVM memory.

Execution is paused until the specified type of the condition is met or timed out Assembly command: WAIT [COND=]<Condition> [TYPE=]<Type> [TIMEOUT=]<Timeout> [DEST=]<Destination> Alternative assembly command: JUMP [DEST=]<Destination> 'COND=', 'TYPE=', 'TIMEOUT=', and 'DEST=' are options. When included, the parameters can be in any order. Condition are listed in #GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/SLVSEA74920. Examples: GPIO1, BUCK1_PG, I2C_1 Type = LOW, HIGH, RISE, or FALL Timeout = timeout value in ns, µs, ms, or s. If no unit is entered, this field must be an integer value between 0-63. Timeout value is be rounded to the nearest achievable time based on the current step size. Current step size is based on the default NVM setting or a SET_DELAY value from a previous command in the same sequence. Assembler reports an error if the step size is too large or too small to meet the delay. Destination = Label to jump to if when timeout occurs. Destination must be after the WAIT statement in memory. Memory space can be either '0' or '1'. '0' indicates the destination address is in the PFSM memory space. '1' indicates the destination address is external and represents a FSM state ID. When using the jump command, the PFSM performs an unconditional jump. The command is be compiled as "WAIT COND=63 TYPE=LOW TIMEOUT=0 DEST=<Destination>". Condition 63 is a hardcoded 1, so the condition is never satisfied and hence always times out. Therefore this command always jumps to the destination. Examples: WAIT GPIO4 RISE 1 s <Destination> 0 — Wait to execute the command at the specified SRAM address when a rise edge is detected at GPIO4, or after 1 second WAIT COND=BUCK1_PG TYPE=HIGH TIMEOUT=500 µs DEST=<mcu2act_seq> — Wait to execute the commands at <mcu2act_seq> address as soon as BUCK1 output is within power-good range, or after 500 µs WAIT Command Conditions COND_SEL Condition Name COND_SEL Condition Name COND_SEL Condition Name COND_SEL Condition Name 0 GPIO1#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 16 LDO1_PG 32 I2C_0#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 48 LP_STANDBY_SEL 1 GPIO2#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 17 LDO2_PG 33 I2C_1#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 49 N/A 2 GPIO3#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 18 LDO3_PG 34 I2C_2#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 50 N/A 3 GPIO4#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 19 LDO4_PG 35 I2C_3#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 51 N/A 4 GPIO5#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 20 PGOOD 36 I2C_4#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 52 N/A 5 GPIO6#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 21 TWARN_EVENT 37 I2C_5#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 53 N/A 6 GPIO7 22 INTERRUPT_PIN 38 I2C_6#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 54 N/A 7 GPIO8 23 N/A 39 I2C_7#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 55 N/A 8 GPIO9 24 N/A 40 SREG0_0#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 56 N/A 9 GPIO10 25 N/A 41 SREG0_1#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 57 N/A 10 GPIO11 26 N/A 42 SREG0_2#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 58 N/A 11 BUCK1_PG 27 N/A 43 SREG0_3#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 59 N/A 12 BUCK2_PG 28 N/A 44 SREG0_4#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 60 N/A 13 BUCK3_PG 29 N/A 45 SREG0_5#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 61 N/A 14 BUCK4_PG 30 N/A 46 SREG0_6#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 62 0 15 BUCK5_PG(use for EXT_VMON PowerGood) 31 N/A 47 SREG0_7#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 63 1 Conditions GPIO1..GPIO6 are only processed if the associated GPIOx pins are configured as GPIO Conditions I2C0..7 refer to register bits TRIGGER_I2C_0..7, and are located in register FSM_I2C_TRIGGER Conditions SREG0_0...7 refer to bits 9...7 in PFSM storage register R0 DELAY_IMM Command Description: Delay the execution by a specified time Assembly command: DELAY_IMM <Delay> Delay = delay time in ns, µs, ms, or s. If no unit is entered, this field must be an integer value between 0-63. Delay value is be rounded to the nearest achievable time based on the current step size. Current step size is based on the default NVM setting or a SET_DELAY value from a previous command. Assembler reports an error if the step size is too large or too small to meet the delay. Examples: DELAY_IMM 100 µs — Delay execution by 100 µs DELAY_IMM 10 ms — Delay execution by 10 ms DELAY_IMM 8 — Delay execution by 8 ticks of the current PFSM time step DELAY_SREG Command Description: Delay the execution by a time value stored in the specified scratch register. The delay is calculated based on the curernt step size based on the value stored in PFSM_DELAY_STEP, or a SET_DELAY value from a previous command. Assembly command: DELAY_SREG <PFSM Storage Register> PFSM Storage Register can be R0, R1, R2, or R3. Examples: DELAY_SREG R0 — Delay execution by the time value stored in PFSM storage register R0 TRIG_SET Command Description: Set a trigger destination address for a given input signal or condition. These commands must be defined at the beginning of PFSM configuration memory. Assembly command: TRIG_SET [DEST=]<Destination> [ID=]<Trig_ID> [SEL=]<Trig_sel> [TYPE=]<Trig_type> [IMM=]<IMM> [EXT=]<Memory space> 'DEST=', 'ID=', 'SEL='. 'TYPE=', 'IMM=', and 'EXT=' are options. When included, the parameters can be in any order. Destination is the label where this trigger starts executing. Trig_ID is the ID of the hardware trigger module to be configured (value range 0-27). They must be defined in numeric order based on the priority of the trigger. Trig_Sel is the 'Trigger Name' from the . This 'Trigger Name' is the trigger signal to be associated with the specified TRIG_ID. Trig_type = LOW, HIGH, RISE, or FALL. IMM can be either '0' or '1'. = '0' if the trigger is not activated until the END command of a given task; '1' if the trigger is activated immediately and can abort a sequence. REENTRANT can be either '0' or '1'. '1' permits a trigger to return to the current state, that allows a self-branching trigger to execute the current sequence again. Memory space can be either '0' or '1'. '0' indicates the destination address is in the PFSM memory space. '1' indicates the destination address is external and represents a FSM state ID. Examples: TRIG_SET seq1 20 GPIO_1 LOW 0 0 — Set trigger 20 to be GPIO_1=Low, not immediate. When triggered, start executing at ‘seq1’ label. TRIG_SET DEST=seq2 ID=15 SEL=WD_ERROR TYPE=RISE IMM=0 EXT=0 — Set trigger 15 to be rising WD_ERROR trigger, not immediate. When triggered, start executing at ‘seq2’ label. TRIG_MASK Command Description: Sets a trigger mask that determines which triggers are active. Setting a ‘0’ enables the trigger, setting a ‘1’ disables (masks) the trigger. Assembly command: TRIG_MASK <Mask value> Mask Value = 28-bit mask in any literal integer format (decimal, hex, and so forth). Examples: TRIG_MASK 0x5FF82F0 — Set the trigger mask to 0x5FF82F0 END Command #GUID-829AAD39-C301-4ED7-A234-62018DE2CD53/X6385 shows the format of the END commands. END Command Format Bit[3:0] CMD 4 bits Description: Marks the final instruction in a sequential task Fields: CMD: Command opcode (0xC) Assembly command: END Configuration Memory Organization and Sequence Execution The configuration memory is loaded from NVM into an SRAM. shows an example configuration memory with only two configured sequences. Configuration Memory Script Example As soon as the PMIC state reaches the mission states, it starts reading from the configuration memory until it hits the first END command. Setting up the triggers (1-28) must be the first section of the configuration memory, as well as the first set of trigger configurations. The trigger configurations are read and mapped to an internal lookup table that contains the starting address associated with each trigger in the configuration memory. If the trigger destination is an FFSM state then the address contains the fixed state value. After the trigger configurations are read and mapped into the SRAM, these triggers control the execution flow of the state transitions. The signal source of each trigger is listed under . When a trigger or multiple triggers are activated, the PFSM execution engine looks up the starting address associated with the highest priority unmasked trigger, and starts executing commands until it hits an END command. The last commands before END statement is generally the TRIG_MASK command, which directs the PFSM to a new set of unmasked trigger configurations, and the trigger with the highest priority in the new set is serviced next. Trigger priority is determined by the Trigger ID associated with each trigger. The priority of the trigger decreases as the associated trigger ID increases. As a result, the critical error triggers are usually located at the lowest trigger IDs. The TRIG_SET commands specify if a trigger is immediate or non-immediate. Immediate triggers are serviced immediately, which involves branching from the current sequence of commands to reach a new target destination. The non-immediate triggers are accumulated and serviced in the order of priority through the execution of each given sequence until the END command in reached. Therefore, the trigger ID assignment for each trigger can be arranged to produce the desired PFSM behavior. The TRIG_MASK command determines which triggers are active at the end of each sequence, and is usually placed just before the END instruction. The TRIG_MASK takes a 28-bit input to allow any combination of triggers to be enabled with a single command. Through the definition of the active triggers after each sequence execution the TRIG_MASK command can be conceptualized as establishing a power state. The above sequence of waiting for triggers and executing the sequence associated with an activated trigger is the normal operating condition of the PFSM execution engine when the PMIC is in the MISSION state. The fixed device power FSM takes over control from the execution engine each time an event occurs that requires a transition from the MISSION state of the PMIC to a fixed device state.

The is used as an example state machine that is defined through the configuration memory using the configuration FSM instructions. Example of a Mission State-Machine Each power state (light blue bubbles in ) defines the ON or OFF state and the sequencing timing of the external regulators and GPIO outputs. This example defines four power states: STANDBY, ACTIVE, MCU ONLY, and DEEP_SLEEP/S2R three power states: STANDBY, ACTIVE and RETENTION states. The priority order of these states is as follows: ACTIVE MCU ONLY DEEP SLEEP/S2R STANDBY The transitions between each power state is determined by the trigger signals source pre-selected from . These triggers are then placed in the order of priority through the trigger ID assignment of each trigger source. The critical error triggers are placed first, some specified as immediate triggers that can interrupt an on-going sequence. The non-error triggers, which are used to enable state transitions during normal device operation, are then placed according to the priority order of the state the device is transitioning to. list the trigger signal sources, in the order of priority, used to define the power states and transitions of the example mission state machine shown in . This table also helps to determine which triggers must be masked by the TRIG_MASK command upon arriving a pre-defined power state to produce the desired PFSM behavior.

When an error occurs, which requires the device to enter directly to the SAFE RECOVERY state, the mask for this trigger must be removed while all other non-immediate triggers are masked. The device exits the mission states and the FFSM state machine takes over control of the device power states once this trigger is executed. Pre-Configured Hardware Transitions There are some pre-defined trigger sources, such as on-requests and off-requests, that are constructed with the combination of hardware input signals and register bits settings. This section provides more detail to these pre-defined trigger sources and shows how they can be utilized in the PFSM configuration to initiate state to state transitions. ON Requests ON requests are used to switch on the device, which then transitions the device from the STANDBY or the LP_STANDBY to the state specified by STARTUP_DEST[1:0]. After the device arrives at the corresponding STARTUP_DEST[1:0] operation state, the MCU must setup the SLEEP1 and NSLEEP2 signals accordingly before clearing the STARTUP_INT interrupt. Once the interrupt is cleared, the device stays or moves to the next state corresponding to the NSLEEP signals state assignment as specified in . #GUID-CF09F512-F01B-4591-9EAD-EE716C2976A4/SLVSEA76972 lists the available ON requests. ON Requests EVENT MASKABLE COMMENT DEBOUNCE nPWRON (pin) Yes Edge sensitive 50 ms ENABLE (pin) Yes Level sensitive 8 µs First Supply Detection (FSD) Yes VCCA > VCCA_UV and FSD unmasked N/A RTC ALARM Interrupt Yes N/A RTC TIMER Interrupt Yes N/A WKUP1 or WKUP2 Detection Yes Edge sensitive 8 µs LP_WKUP1 or LP_WKUP2 Detection Yes Edge sensitive N/A Recovery from Immediate and Orderly Shutdown No Recover from system errors which caused immediate or orderly shutdown of the device N/A If one of the events listed in #GUID-CF09F512-F01B-4591-9EAD-EE716C2976A4/SLVSEA76972 occurs, then the event powers on the device unless one of the gating conditions listed in #GUID-CF09F512-F01B-4591-9EAD-EE716C2976A4/SLVSEA71946 is present. ON Requests Gating Conditions EVENT MASKABLE COMMENT VCCA_OVP (event) No VCCA > VCCA_OVP Device stays in SAFE RECOVERY until VCCA < VCCA_OVP VCCA_UVLO (event) No VCCA < VCCA_UVLO VINT_OVP (event) No LDOVINT > 1.98 V VINT_UVLO (event) No LDOVINT < 1.62 V TSD (event) No Device stays in SAFE RECOVERY until temperature decreases below TWARN level The NPWRON_SEL NVM register bit determines whether the nPWRON/ENABLE pin is treated as a power on press button or a level sensitive enable switch. When this pin is configured as the nPWRON button, a short button press detection is latched internally as a device enable signal until the NPWRON_START_INT is cleared, or a long press key event is detected. The short button press detection occurs when an falling edge is detected at the nPWRON pin. When the NPWRON_START_MASK bit is set to '1', the device does no longer react to the changing state of the pin as the nPWRON press button. The nPWRON/ENABLE pin is a level sensitive pin when it is configured as an ENABLE pin, and an assertion enables the device until the pin is released. When the ENABLE_MASK bit is set to '1', the device does no longer react to the changing state of the pin as the ENABLE switch. OFF Requests An OFF request is used to orderly switch off the device. OFF requests initiate transition from any other mission state to the STANDBY state or the LP_STANDBY state depending on the setting of the LP_STANDBY_SEL bit. #GUID-117B0898-2FEC-4E9D-9F33-06019819BC63/SLVSEA7991 lists the conditions to generate the OFF requests and the corresponding destination state. OFF Requests EVENT DEBOUNCE LP_STANDBY_SEL BIT SETTING DESTINATION STATE nPWRON (pin) (long press key event) 8 s LP_STANDBY_SEL = 0 STANDBY LP_STANDBY_SEL = 1 LP_STANDBY ENABLE (pin) 8 µs LP_STANDBY_SEL = 0 STANDBY LP_STANDBY_SEL = 1 LP_STANDBY I2C_TRIGGER_0 NA LP_STANDBY_SEL = 0 STANDBY LP_STANDBY_SEL = 1 LP_STANDBY The long press key event occurs when the nPWRON pin stays low for longer than tLPK_TIME while the device is in a mission state. When the nPWRON or ENABLE pin is used as the OFF request, the device wakes up from the STANDBY or the LP_STANDBY state through the ON request initiated by the same pin. The NPWRON_START_MASK or the ENABLE_MASK must remain low in this case to allow the detection of the ON request initiated by the pin. If the device needs to enter the LP_STANDBY state through the OFF request, it is important that the state of the nPWRON or ENABLE pin must remain the same until the state transition is completed. Failure to do so may result in unsuccessful wake-up from the LP_STANDBY state when the pin re-initiates On request. Using the I2C_TRIGGER_0 bit as the OFF request enables the device to wake up from the STANDBY or the LP_STANDBY states through the detection of LP_WKUPn/WKUPn pins, as well as RTC alarm or timer interrupts. To enable this feature, the device must set the I2C_TRIGGER_0 bit to '1' while the NSLEEPn signals are masked, and the ON request (initialized by the nPWRON or ENABLE pins) must remain active. Also the interrupt bits ENABLE_INT, FSD_INT and the GPIOx_INT bits (for the GPIOx pins assigned as WKUP1 or WKUP2) must be cleared before setting the I2C_TRIGGER_0 bit to '1'. NSLEEP1 and NSLEEP2 Functions The SLEEP requests are activated through the assertion of nSLEEP1 or nSLEEP2 pins that are the secondary functions of the 11 GPIO pins. These pins can be selected through GPIO configuration using the GPIOx_SEL register bits. If the nSLEEP1 or nSLEEP2 pins are not available, the NSLEEP1B and NSLEEP2B register bits can be configured in place for their functions. The input of nSLEEP1 pin and the state of the NSLEEP1B register bit are combined to create the NSLEEP1 signal through an OR function. Similarly for the input of the nSLEEP2 pin and the NSLEEP2B register bit as they are combined to create the NSLEEP2 signal. A 1 → 0 logic level transition of the NSLEEP signal generates a sleep request, while a 0 → 1 logic level transition reverses the sleep request in the example PFSM from . When a NSLEEPn signal transitions from 1 → 0, it generates a sleep request to go from a higher power state to a lower power state. When the signal transitions from 0 → 1, it reverses the sleep request and returns the device to the higher power state. The NSLEEP1 signal is designed to control the SoC supply rails. The NSLEEP2 signal is designed to control the MCU supply rails. When NSLEEP1 signal changes from 1 → 0, depending on the state of NSLEEP2, the TPS6593-Q1 device exits ACTIVE state and enters either the MCU ONLY or the S2R states. When NSLEEP2 signal changes from 1 → 0, the device enters the S2R state regardless the state of NSLEEP1. When the NSLEEP2 input signal changes from 0 →1, the MCU supply rails are enabled and the device exits S2R state. Depending on the state of NSLEEP1 signal, the device enters either the MCU ONLY or the ACTIVE state. In order for the system to function correctly, the MCU rails must be enabled when the NSLEEP1 input signal changes from 0 →1, which enables the SOC supply rails. NSLEEP1 0 →1 transition is ignored if NSLEEP2 is 0. The NSLEEPn_MASK bit can be used to mask the sleep request associated with the corresponding NSLEEPn signal. When the NSLEEPn_MASK = 1, the corresponding NSLEEPn signal is ignored. shows how the combination of the NSLEEPn signals and NSLEEPn_MASK bits creates triggers A/B/C/D to the FSM to control the power state of the device. The states of the resources during ACTIVE, SLEEP, and DEEP SLEEP/S2R states are defined in the LDOn_CTRL and BUCKn_CTRL registers. For each resource, a transition to the MCU ONLY or the DEEP SLEEP/S2R states is controlled by the FSM when the resource is associated to the SLEEP or DEEP SLEEP/S2R states. shows the corresponding state assignment based on the state of the NSLEEPn and their corresponding mask signals using the example PFSM from .

Any one of these GPIO pins when configured as an input pin can be configured to wake up the device by setting GPIOn_SEL bit to select the WKUP1 or WKUP2 functions. In the example PFSM depicted in , when a GPIO pin is configured as a WKUP1 pin, a rising or falling edge detected at the input of this pin (configurable by the GPIOn_FALL_MASK and the GPIOn_RISE_MASK bits) wakes up the device to the ACTIVE state. Likewise if a GPIO pin is configured as a WKUP2 pin, a detected edge wakes up the device to the MCU ONLY state. If multiple edge detections of WKUP signals occur simultaneous, the device goes to the state in the following priority order: ACTIVE MCU ONLY When a valid edge is detected at a WKUP pin, the nINT pin generates an interrupt to signal the MCU of the wake-up event, and the GPIOx_INT interrupt bit is set. The wake request remains active until the GPIOx_INT bit is cleared by the MCU. While the wake request is executing, the device does not react to sleep requests to enter a lower power state until the corresponding GPIOx_INT interrupt bit is cleared to cancel the wake request. After the wake request is canceled, the device returns to the state indicated by the NSLEEP1 and NSLEEP2 signals as shown in . LP_WKUP Pins for Waking Up from LP STANDBY The LP_WKUP functions are activated through the edge detection of LP_WKUP pins, configurable as secondary functions of GPIO3 and GPIO4. They are specially designed to wake the device up from the LP STANDBY state when a high speed wake-up signal is detected. Similar to the WKUP1 and WKUP2 pins, when GPIO3 or GPIO4 pin is configured as an LP_WKUP1 pin, a rising or falling edge detected at the input of this pin (configurable by the GPIOn_FALL_MASK and the GPIOn_RISE_MASK bits) wakes up the device to the ACTIVE state. Likewise, if the pin is configured as an LP_WKUP2 pin, a detected edge wakes up the device to the MCU ONLY state. If multiple edge detections of LP_WKUP signals occur simultaneously, the device goes to the state in the following priority order: ACTIVE MCU ONLY Due to a digital control erratum in the device, the ENABLE_MASK/NPWRON_START_MASK bit must be set to '1' before the device enters LP_STANDBY state in order for the LP_WKUP2 pin to correctly wake up the device to the MCU_ONLY state. The TPS6593-Q1 device supports limited CAN wake-up capability through the LP_WKUP1/2 pins. When an input signal (without deglitch) with logic level transition from high-to-low or low-to-high with a minimum pulse width of tWK_PW_MIN is detected on the assigned LP_WKUP1/2 pins, the device wakes up asynchronously and executes the power up sequence. CAN-transceiver RXD- or INH-outputs can be connected to the LP_WKUP pin. If RXD-output is used, it is assumed that the transceiver RXD-pin IO is powered by the transceiver itself from an external supply when TPS6593-Q1 is in the LP_STANDBY state. If INH-signal is used it has to be scaled down to the recommenced GPIO input voltage level specified in the electrical characteristics table. In this PFSM example, the device can wake up from the LP_STANDBY state through the detection of LP_WKUP pins only if it enters the LP_STANDBY state through the TRIGGER_I2C_0 OFF request while the NSLEEPn signals are masked, and the on request initialized by the nPWRON/ENABLE pin remains active. Once a valid wake-up signal is detected at the LP_WKUP pin, it is handled as a WAKE request. The nINT pin generates an interrupt to signal the MCU of the wake-up event, and the corresponding GPIOx_INT interrupt bit is set. The wake request remains active until the interrupt bit is cleared by the MCU. shows how the device returns to the state indicated by the NSLEEP1 and NSLEEP2 signals after the wake request is canceled. illustrates the valid wake-up signal at the LP_WKUP1/2 pins, and the generation and clearing of the internal wake-up signal. CAN Wake-Up Timing Diagram Pre-Configurable Mission States When the device arrives at a mission state, all rail sequencing is controlled by the pre-configurable FSM engine (PFSM) through the configuration memory. The configuration memory allows configurations of the triggers and the operation states that together form the configurable sub state machine within the scope of mission states. This sub state machine can be used to control and sequence the different voltage outputs as well as any GPIO outputs that can be used as enable for external rails. When the device is in a mission state, it has the capacity to supply the processor and other platform modules depending on the power rail configuration. The definitions and transition triggers of the mission states are configurable through the NVM configuration. Unlike the user registers, the PFSM definition stored in the NVM cannot be modified during normal operation. When the PMIC determines that a transition to another operation state is necessary, it reads the configuration memory to determine what sequencing is needed for the state transition. Furthermore, the PFSM has four storage registers, further referred to as PFSM storage registers (R0-3). shows how the trigger signals for each state transition can come from a variety of interface or GPIO inputs, or potential error sources. shows how the device processes all of the possible error sources inside the PFSM engine, a hierarchical mask system is applied to filter out the common errors that can be handled by interrupt only, and categorize the other error sources as Severe Global Error, Moderate Global Error, and so forth. The filtered and categorized triggers are sent into the PFSM engine, that then determines the entry and exit condition for each configured mission state. Error Source Hierarchical Mask System shows an example of how the PFSM engine utilizes instructions to execute the configured device state and sequence transitions of the mission state-machine. provides the instruction set and usage description of each instruction in the following sections. describes how the instructions are stored in the NVM memory.

These two bits are then left shifted 2 bit-positions to give full byte value of 0bxx10xxxx, hence sets bits 5:4 to 0b10. REG_WRITE_VOUT_IMM Command Description: Write the target voltage of a specified regulator after a specified delay. This command is a spin-off of the REG_WRITE_IMM command with the intention to save instruction bits. Assembly command: REG_WRITE_VOUT_IMM [REGULATOR=]<Regulator ID> [SEL=]<VSEL> [VOUT=]<Vout> [DELAY=]<Delay>[BYPASS=]<BYPASS> 'REGULATOR=', ''SEL=', 'VOUT=', 'DELAY=' and 'BYPASS=' are syntax options. When included, the parameters can be in any order. Regulator ID = BUCK1, BUCK2, BUCK3, BUCK4 , BUCK5, LDO1, LDO2, LDO3, or LDO4. VSEL selects the BUCKn_VSET1 or BUCKn_VSET2 bits which the command writes to if Regulator ID is BUCK1-5. VSEL is defined as: '0': BUCKn_VSET1, '1': BUCKn_VSET2, '2': Currently Active BUCKn_VSET, '3': Currently Inactive BUCKn_VSET. If Regulator ID is LDO1-4, VSEL value is ignored. VOUT = output voltage in mV or V. Unit must be listed. DELAY = delay time in ns, µs, ms, or s. If no unit is entered, this field must be an integer value between 0-63, which becomes the threshold count for the counter running a step size specified in the register PFSM_DELAY_STEP. The delay value is rounded to the nearest achievable delay time based on the current step size. Current step size is based on the default NVM setting or a SET_DELAY value from a previous command in the same sequence. Assembler reports an error if the step size is too large or too small to meet the delay. BYPASS selects whether the selected LDO needs to operate in linear mode (BYPASS=0) or bypass mode (BYPASS=1) Examples: REG_WRITE_VOUT_IMM BUCK3 2 1.05 V 100 µs — Sets BUCK3 to 1.05 V by updating the active BUCK3_VSET register after 100 µs REG_WRITE_VOUT_IMM REGULATOR=LDO1 SEL=0 VOUT=700 mV DELAY=6 ms BYPASS=0 — Sets LDO1 to 700 mV in linear mode after 6 ms. REG_WRITE_VOUT_IMM REGULATOR=LDO2 SEL=0 VOUT=3.3V DELAY=0 ms BYPASS=1 — Sets LDO2 to 3.3VV in bypass mode after 0 ms REG_WRITE_VCTRL_IMM Command Description: Write the operation mode of a specified regulator after a specified delay. This command is a spin-off of the REG_WRITE_IMM command with the intention to save instruction bits. Assembly command: REG_WRITE_VCTRL_IMM [REGULATOR=]<Regulator ID> [VCTRL=]<VCTRL> [MASK=]<Mask> [DELAY=]<Delay> [DELAY_MODE=]<Delay Mode> 'REGULATOR=', 'VCTRL=', 'MASK=', and 'DELAY=' are options. When included, the parameters can be in any order. Regulator ID = BUCK1, BUCK2, BUCK3, BUCK4, BUCK5, LDO1, LDO2, LDO3, or LDO4. VCTRL = 0-15, in hex, decimal, or binary format. Data to write to the following regulator control fields: BUCKs: BUCKn_PLDN, BUCKn_VMON_EN, BUCKn_VSEL, BUCKn _FPWM_MP, BUCKn_FPWM, and BUCKn_EN LDOs: LDOn_PLDN, LDOn_VMON_EN, 0, 0, LDOn_EN DELAY = delay time in ns, µs, ms, or s. If no unit is entered, this field must be an integer value between 0-63, which becomes the threshold count for the counter running a step size specified in the register PFSM_DELAY_STEP. Delay value is be rounded to the nearest achievable delay time based on the current step size. Current step size is based on the default NVM setting or a SET_DELAY value from a previous command in the same sequence. Assembler reports an error if the step size is too large or too small to meet the delay. Delay Mode must be one of the below options: MATCH_EN = 0 (Delay if VCTRL enable bit mismatches) MATCH_ALL = 1 (Delay if any VCTRL bits mismatch) ALWAYS = 2 (Delay always) Examples: REG_WRITE_VCTRL_IMM BUCK3 0x00 0xE0 100 µs — Sets BUCK3 to OFF (VCTRL bits = 0b00000) after 100 µs REG_WRITE_VCTRL_IMM REGULATOR=LDO1 VCTRL=0x09 MASK=0x36 DELAY=10 ms — Set LDO1_VMON and LDO1_EN to '1' after 10 ms REG_WRITE_MASK_SREG Command Description: Write the data from a PFSM storage register, except the masked bits, to the specified register address Assembly command: REG_WRITE_MASK_SREG [REG=]<PFSM Storage Register> [ADDR=]<Address> [MASK=]<Mask> 'REG=', 'ADDR=', and 'MASK=' are options. When included, the parameters can be in any order. PFSM Storage Register can be R0, R1, R2, or R3. Address and Mask can be in any literal integer format (decimal, hex, and so forth). Examples: REG_WRITE_MASK_SREG R2 0x22 0x00 — Write the content of PFSM storage register R2 to address 0x22 REG_WRITE_MASK_SREG REG=R0 ADDR=0x054 MASK=0xF0 — Write the lower 4 bits of PFSM storage register R0 to address 0x54 SREG_READ_REG Command Description: Write PFSM storage register (R0-3) with data from a specified address Assembly command: SREG_READ_REG [REG=]<PFSM Storage Register> [ADDR=]<Address> 'REG=' and 'ADDR=' are options. When included, the parameters can be in any order. PFSM Storage Register can be R0, R1, R2, or R3. Address can be in any literal integer format (decimal, hex, and so forth). Examples: SREG_READ_REG R2 0x15 — Read the content of address 0x15 and write the data to PFSM storage register R2 SREG_READ_REG ADDR=0x077 REG=R3 — Read the content of address 0x77 and write the data to PFSM storage register R3 SREG_WRITE_IMM Command Description: Write the specified data to the scratch register (R0-3) Assembly command: SREG_WRITE_IMM [REG=]<PFSM Storage Register> [DATA=]<Data> Data can be in any literal integer format (decimal, hex, and so forth). PFSM Storage Register can be R0, R1, R2, or R3. 'REG=' and 'DATA=' are options. When included, the parameters can be in any order. Examples: SREG_WRITE_IMM R2 0x15 — Write 0x15 to PFSM storage register R2 SREG_WRITE_IMM ADDR=0x077 REG=R3 — Read 0x77 to PFSM storage register R3 WAIT Command Description: Wait upon a condition of a given type. Execution is paused until the specified type of the condition is met or timed out Assembly command: WAIT [COND=]<Condition> [TYPE=]<Type> [TIMEOUT=]<Timeout> [DEST=]<Destination> Alternative assembly command: JUMP [DEST=]<Destination> 'COND=', 'TYPE=', 'TIMEOUT=', and 'DEST=' are options. When included, the parameters can be in any order. Condition are listed in #GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/SLVSEA74920. Examples: GPIO1, BUCK1_PG, I2C_1 Type = LOW, HIGH, RISE, or FALL Timeout = timeout value in ns, µs, ms, or s. If no unit is entered, this field must be an integer value between 0-63. Timeout value is be rounded to the nearest achievable time based on the current step size. Current step size is based on the default NVM setting or a SET_DELAY value from a previous command in the same sequence. Assembler reports an error if the step size is too large or too small to meet the delay. Destination = Label to jump to if when timeout occurs. Destination must be after the WAIT statement in memory. Memory space can be either '0' or '1'. '0' indicates the destination address is in the PFSM memory space. '1' indicates the destination address is external and represents a FSM state ID. When using the jump command, the PFSM performs an unconditional jump. The command is be compiled as "WAIT COND=63 TYPE=LOW TIMEOUT=0 DEST=<Destination>". Condition 63 is a hardcoded 1, so the condition is never satisfied and hence always times out. Therefore this command always jumps to the destination. Examples: WAIT GPIO4 RISE 1 s <Destination> 0 — Wait to execute the command at the specified SRAM address when a rise edge is detected at GPIO4, or after 1 second WAIT COND=BUCK1_PG TYPE=HIGH TIMEOUT=500 µs DEST=<mcu2act_seq> — Wait to execute the commands at <mcu2act_seq> address as soon as BUCK1 output is within power-good range, or after 500 µs WAIT Command Conditions COND_SEL Condition Name COND_SEL Condition Name COND_SEL Condition Name COND_SEL Condition Name 0 GPIO1#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 16 LDO1_PG 32 I2C_0#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 48 LP_STANDBY_SEL 1 GPIO2#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 17 LDO2_PG 33 I2C_1#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 49 N/A 2 GPIO3#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 18 LDO3_PG 34 I2C_2#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 50 N/A 3 GPIO4#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 19 LDO4_PG 35 I2C_3#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 51 N/A 4 GPIO5#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 20 PGOOD 36 I2C_4#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 52 N/A 5 GPIO6#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 21 TWARN_EVENT 37 I2C_5#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 53 N/A 6 GPIO7 22 INTERRUPT_PIN 38 I2C_6#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 54 N/A 7 GPIO8 23 N/A 39 I2C_7#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 55 N/A 8 GPIO9 24 N/A 40 SREG0_0#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 56 N/A 9 GPIO10 25 N/A 41 SREG0_1#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 57 N/A 10 GPIO11 26 N/A 42 SREG0_2#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 58 N/A 11 BUCK1_PG 27 N/A 43 SREG0_3#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 59 N/A 12 BUCK2_PG 28 N/A 44 SREG0_4#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 60 N/A 13 BUCK3_PG 29 N/A 45 SREG0_5#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 61 N/A 14 BUCK4_PG 30 N/A 46 SREG0_6#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 62 0 15 BUCK5_PG(use for EXT_VMON PowerGood) 31 N/A 47 SREG0_7#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 63 1 Conditions GPIO1..GPIO6 are only processed if the associated GPIOx pins are configured as GPIO Conditions I2C0..7 refer to register bits TRIGGER_I2C_0..7, and are located in register FSM_I2C_TRIGGER Conditions SREG0_0...7 refer to bits 9...7 in PFSM storage register R0 DELAY_IMM Command Description: Delay the execution by a specified time Assembly command: DELAY_IMM <Delay> Delay = delay time in ns, µs, ms, or s. If no unit is entered, this field must be an integer value between 0-63. Delay value is be rounded to the nearest achievable time based on the current step size. Current step size is based on the default NVM setting or a SET_DELAY value from a previous command. Assembler reports an error if the step size is too large or too small to meet the delay. Examples: DELAY_IMM 100 µs — Delay execution by 100 µs DELAY_IMM 10 ms — Delay execution by 10 ms DELAY_IMM 8 — Delay execution by 8 ticks of the current PFSM time step DELAY_SREG Command Description: Delay the execution by a time value stored in the specified scratch register. The delay is calculated based on the curernt step size based on the value stored in PFSM_DELAY_STEP, or a SET_DELAY value from a previous command. Assembly command: DELAY_SREG <PFSM Storage Register> PFSM Storage Register can be R0, R1, R2, or R3. Examples: DELAY_SREG R0 — Delay execution by the time value stored in PFSM storage register R0 TRIG_SET Command Description: Set a trigger destination address for a given input signal or condition. These commands must be defined at the beginning of PFSM configuration memory. Assembly command: TRIG_SET [DEST=]<Destination> [ID=]<Trig_ID> [SEL=]<Trig_sel> [TYPE=]<Trig_type> [IMM=]<IMM> [EXT=]<Memory space> 'DEST=', 'ID=', 'SEL='. 'TYPE=', 'IMM=', and 'EXT=' are options. When included, the parameters can be in any order. Destination is the label where this trigger starts executing. Trig_ID is the ID of the hardware trigger module to be configured (value range 0-27). They must be defined in numeric order based on the priority of the trigger. Trig_Sel is the 'Trigger Name' from the . This 'Trigger Name' is the trigger signal to be associated with the specified TRIG_ID. Trig_type = LOW, HIGH, RISE, or FALL. IMM can be either '0' or '1'. = '0' if the trigger is not activated until the END command of a given task; '1' if the trigger is activated immediately and can abort a sequence. REENTRANT can be either '0' or '1'. '1' permits a trigger to return to the current state, that allows a self-branching trigger to execute the current sequence again. Memory space can be either '0' or '1'. '0' indicates the destination address is in the PFSM memory space. '1' indicates the destination address is external and represents a FSM state ID. Examples: TRIG_SET seq1 20 GPIO_1 LOW 0 0 — Set trigger 20 to be GPIO_1=Low, not immediate. When triggered, start executing at ‘seq1’ label. TRIG_SET DEST=seq2 ID=15 SEL=WD_ERROR TYPE=RISE IMM=0 EXT=0 — Set trigger 15 to be rising WD_ERROR trigger, not immediate. When triggered, start executing at ‘seq2’ label. TRIG_MASK Command Description: Sets a trigger mask that determines which triggers are active. Setting a ‘0’ enables the trigger, setting a ‘1’ disables (masks) the trigger. Assembly command: TRIG_MASK <Mask value> Mask Value = 28-bit mask in any literal integer format (decimal, hex, and so forth). Examples: TRIG_MASK 0x5FF82F0 — Set the trigger mask to 0x5FF82F0 END Command #GUID-829AAD39-C301-4ED7-A234-62018DE2CD53/X6385 shows the format of the END commands.

When included, the parameters can be in any order. Regulator ID = BUCK1, BUCK2, BUCK3, BUCK4 , BUCK5, LDO1, LDO2, LDO3, or LDO4. VSEL selects the BUCKn_VSET1 or BUCKn_VSET2 bits which the command writes to if Regulator ID is BUCK1-5. VSEL is defined as: '0': BUCKn_VSET1, '1': BUCKn_VSET2, '2': Currently Active BUCKn_VSET, '3': Currently Inactive BUCKn_VSET. If Regulator ID is LDO1-4, VSEL value is ignored. VOUT = output voltage in mV or V. Unit must be listed. DELAY = delay time in ns, µs, ms, or s. If no unit is entered, this field must be an integer value between 0-63, which becomes the threshold count for the counter running a step size specified in the register PFSM_DELAY_STEP. The delay value is rounded to the nearest achievable delay time based on the current step size. Current step size is based on the default NVM setting or a SET_DELAY value from a previous command in the same sequence. Assembler reports an error if the step size is too large or too small to meet the delay.

When included, the parameters can be in any order. Condition are listed in #GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/SLVSEA74920. Examples: GPIO1, BUCK1_PG, I2C_1 Type = LOW, HIGH, RISE, or FALL Timeout = timeout value in ns, µs, ms, or s. If no unit is entered, this field must be an integer value between 0-63. Timeout value is be rounded to the nearest achievable time based on the current step size. Current step size is based on the default NVM setting or a SET_DELAY value from a previous command in the same sequence. Assembler reports an error if the step size is too large or too small to meet the delay. Destination = Label to jump to if when timeout occurs. Destination must be after the WAIT statement in memory. Memory space can be either '0' or '1'. '0' indicates the destination address is in the PFSM memory space. '1' indicates the destination address is external and represents a FSM state ID. When using the jump command, the PFSM performs an unconditional jump. The command is be compiled as "WAIT COND=63 TYPE=LOW TIMEOUT=0 DEST=<Destination>". Condition 63 is a hardcoded 1, so the condition is never satisfied and hence always times out. Therefore this command always jumps to the destination. Examples: WAIT GPIO4 RISE 1 s <Destination> 0 — Wait to execute the command at the specified SRAM address when a rise edge is detected at GPIO4, or after 1 second WAIT COND=BUCK1_PG TYPE=HIGH TIMEOUT=500 µs DEST=<mcu2act_seq> — Wait to execute the commands at <mcu2act_seq> address as soon as BUCK1 output is within power-good range, or after 500 µs WAIT Command Conditions COND_SEL Condition Name COND_SEL Condition Name COND_SEL Condition Name COND_SEL Condition Name 0 GPIO1#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 16 LDO1_PG 32 I2C_0#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 48 LP_STANDBY_SEL 1 GPIO2#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 17 LDO2_PG 33 I2C_1#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 49 N/A 2 GPIO3#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 18 LDO3_PG 34 I2C_2#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 50 N/A 3 GPIO4#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 19 LDO4_PG 35 I2C_3#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 51 N/A 4 GPIO5#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 20 PGOOD 36 I2C_4#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 52 N/A 5 GPIO6#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 21 TWARN_EVENT 37 I2C_5#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 53 N/A 6 GPIO7 22 INTERRUPT_PIN 38 I2C_6#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 54 N/A 7 GPIO8 23 N/A 39 I2C_7#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 55 N/A 8 GPIO9 24 N/A 40 SREG0_0#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 56 N/A 9 GPIO10 25 N/A 41 SREG0_1#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 57 N/A 10 GPIO11 26 N/A 42 SREG0_2#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 58 N/A 11 BUCK1_PG 27 N/A 43 SREG0_3#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 59 N/A 12 BUCK2_PG 28 N/A 44 SREG0_4#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 60 N/A 13 BUCK3_PG 29 N/A 45 SREG0_5#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 61 N/A 14 BUCK4_PG 30 N/A 46 SREG0_6#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 62 0 15 BUCK5_PG(use for EXT_VMON PowerGood) 31 N/A 47 SREG0_7#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 63 1 Conditions GPIO1..GPIO6 are only processed if the associated GPIOx pins are configured as GPIO Conditions I2C0..7 refer to register bits TRIGGER_I2C_0..7, and are located in register FSM_I2C_TRIGGER Conditions SREG0_0...7 refer to bits 9...7 in PFSM storage register R0 WAIT Command Description: Wait upon a condition of a given type.

Examples: WAIT GPIO4 RISE 1 s <Destination> 0 — Wait to execute the command at the specified SRAM address when a rise edge is detected at GPIO4, or after 1 second WAIT COND=BUCK1_PG TYPE=HIGH TIMEOUT=500 µs DEST=<mcu2act_seq> — Wait to execute the commands at <mcu2act_seq> address as soon as BUCK1 output is within power-good range, or after 500 µs WAIT Command Conditions COND_SEL Condition Name COND_SEL Condition Name COND_SEL Condition Name COND_SEL Condition Name 0 GPIO1#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 16 LDO1_PG 32 I2C_0#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 48 LP_STANDBY_SEL 1 GPIO2#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 17 LDO2_PG 33 I2C_1#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 49 N/A 2 GPIO3#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 18 LDO3_PG 34 I2C_2#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 50 N/A 3 GPIO4#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 19 LDO4_PG 35 I2C_3#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 51 N/A 4 GPIO5#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 20 PGOOD 36 I2C_4#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 52 N/A 5 GPIO6#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-C417A347-6FAF-4664-9900-C36884A4D9C9 21 TWARN_EVENT 37 I2C_5#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 53 N/A 6 GPIO7 22 INTERRUPT_PIN 38 I2C_6#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 54 N/A 7 GPIO8 23 N/A 39 I2C_7#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-073C9416-03E5-4473-A579-3C7FA3652ACB 55 N/A 8 GPIO9 24 N/A 40 SREG0_0#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 56 N/A 9 GPIO10 25 N/A 41 SREG0_1#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 57 N/A 10 GPIO11 26 N/A 42 SREG0_2#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 58 N/A 11 BUCK1_PG 27 N/A 43 SREG0_3#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 59 N/A 12 BUCK2_PG 28 N/A 44 SREG0_4#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 60 N/A 13 BUCK3_PG 29 N/A 45 SREG0_5#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 61 N/A 14 BUCK4_PG 30 N/A 46 SREG0_6#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 62 0 15 BUCK5_PG(use for EXT_VMON PowerGood) 31 N/A 47 SREG0_7#GUID-7E4B8711-0499-4448-BFE4-B3A80B168C5B/GUID-F2425724-D866-47A8-8CE9-4FFFAD773FB7 63 1 Conditions GPIO1..GPIO6 are only processed if the associated GPIOx pins are configured as GPIO Conditions I2C0..7 refer to register bits TRIGGER_I2C_0..7, and are located in register FSM_I2C_TRIGGER Conditions SREG0_0...7 refer to bits 9...7 in PFSM storage register R0 Description: Wait upon a condition of a given type.

Configuration Memory Script Example As soon as the PMIC state reaches the mission states, it starts reading from the configuration memory until it hits the first END command. Setting up the triggers (1-28) must be the first section of the configuration memory, as well as the first set of trigger configurations. The trigger configurations are read and mapped to an internal lookup table that contains the starting address associated with each trigger in the configuration memory. If the trigger destination is an FFSM state then the address contains the fixed state value. After the trigger configurations are read and mapped into the SRAM, these triggers control the execution flow of the state transitions. The signal source of each trigger is listed under . When a trigger or multiple triggers are activated, the PFSM execution engine looks up the starting address associated with the highest priority unmasked trigger, and starts executing commands until it hits an END command. The last commands before END statement is generally the TRIG_MASK command, which directs the PFSM to a new set of unmasked trigger configurations, and the trigger with the highest priority in the new set is serviced next. Trigger priority is determined by the Trigger ID associated with each trigger. The priority of the trigger decreases as the associated trigger ID increases. As a result, the critical error triggers are usually located at the lowest trigger IDs. The TRIG_SET commands specify if a trigger is immediate or non-immediate. Immediate triggers are serviced immediately, which involves branching from the current sequence of commands to reach a new target destination. The non-immediate triggers are accumulated and serviced in the order of priority through the execution of each given sequence until the END command in reached. Therefore, the trigger ID assignment for each trigger can be arranged to produce the desired PFSM behavior. The TRIG_MASK command determines which triggers are active at the end of each sequence, and is usually placed just before the END instruction. The TRIG_MASK takes a 28-bit input to allow any combination of triggers to be enabled with a single command. Through the definition of the active triggers after each sequence execution the TRIG_MASK command can be conceptualized as establishing a power state. The above sequence of waiting for triggers and executing the sequence associated with an activated trigger is the normal operating condition of the PFSM execution engine when the PMIC is in the MISSION state. The fixed device power FSM takes over control from the execution engine each time an event occurs that requires a transition from the MISSION state of the PMIC to a fixed device state.

Configuration Memory Script Example As soon as the PMIC state reaches the mission states, it starts reading from the configuration memory until it hits the first END command. Setting up the triggers (1-28) must be the first section of the configuration memory, as well as the first set of trigger configurations. The trigger configurations are read and mapped to an internal lookup table that contains the starting address associated with each trigger in the configuration memory. If the trigger destination is an FFSM state then the address contains the fixed state value. After the trigger configurations are read and mapped into the SRAM, these triggers control the execution flow of the state transitions. The signal source of each trigger is listed under . When a trigger or multiple triggers are activated, the PFSM execution engine looks up the starting address associated with the highest priority unmasked trigger, and starts executing commands until it hits an END command. The last commands before END statement is generally the TRIG_MASK command, which directs the PFSM to a new set of unmasked trigger configurations, and the trigger with the highest priority in the new set is serviced next. Trigger priority is determined by the Trigger ID associated with each trigger. The priority of the trigger decreases as the associated trigger ID increases. As a result, the critical error triggers are usually located at the lowest trigger IDs. The TRIG_SET commands specify if a trigger is immediate or non-immediate. Immediate triggers are serviced immediately, which involves branching from the current sequence of commands to reach a new target destination. The non-immediate triggers are accumulated and serviced in the order of priority through the execution of each given sequence until the END command in reached. Therefore, the trigger ID assignment for each trigger can be arranged to produce the desired PFSM behavior. The TRIG_MASK command determines which triggers are active at the end of each sequence, and is usually placed just before the END instruction. The TRIG_MASK takes a 28-bit input to allow any combination of triggers to be enabled with a single command. Through the definition of the active triggers after each sequence execution the TRIG_MASK command can be conceptualized as establishing a power state. The above sequence of waiting for triggers and executing the sequence associated with an activated trigger is the normal operating condition of the PFSM execution engine when the PMIC is in the MISSION state. The fixed device power FSM takes over control from the execution engine each time an event occurs that requires a transition from the MISSION state of the PMIC to a fixed device state.

The is used as an example state machine that is defined through the configuration memory using the configuration FSM instructions. Example of a Mission State-Machine Each power state (light blue bubbles in ) defines the ON or OFF state and the sequencing timing of the external regulators and GPIO outputs. This example defines four power states: STANDBY, ACTIVE, MCU ONLY, and DEEP_SLEEP/S2R three power states: STANDBY, ACTIVE and RETENTION states. The priority order of these states is as follows: ACTIVE MCU ONLY DEEP SLEEP/S2R STANDBY The transitions between each power state is determined by the trigger signals source pre-selected from . These triggers are then placed in the order of priority through the trigger ID assignment of each trigger source. The critical error triggers are placed first, some specified as immediate triggers that can interrupt an on-going sequence. The non-error triggers, which are used to enable state transitions during normal device operation, are then placed according to the priority order of the state the device is transitioning to. list the trigger signal sources, in the order of priority, used to define the power states and transitions of the example mission state machine shown in .

The device exits the mission states and the FFSM state machine takes over control of the device power states once this trigger is executed. Pre-Configured Hardware Transitions There are some pre-defined trigger sources, such as on-requests and off-requests, that are constructed with the combination of hardware input signals and register bits settings. This section provides more detail to these pre-defined trigger sources and shows how they can be utilized in the PFSM configuration to initiate state to state transitions. ON Requests ON requests are used to switch on the device, which then transitions the device from the STANDBY or the LP_STANDBY to the state specified by STARTUP_DEST[1:0]. After the device arrives at the corresponding STARTUP_DEST[1:0] operation state, the MCU must setup the SLEEP1 and NSLEEP2 signals accordingly before clearing the STARTUP_INT interrupt. Once the interrupt is cleared, the device stays or moves to the next state corresponding to the NSLEEP signals state assignment as specified in . #GUID-CF09F512-F01B-4591-9EAD-EE716C2976A4/SLVSEA76972 lists the available ON requests.

When this pin is configured as the nPWRON button, a short button press detection is latched internally as a device enable signal until the NPWRON_START_INT is cleared, or a long press key event is detected. The short button press detection occurs when an falling edge is detected at the nPWRON pin. When the NPWRON_START_MASK bit is set to '1', the device does no longer react to the changing state of the pin as the nPWRON press button. The nPWRON/ENABLE pin is a level sensitive pin when it is configured as an ENABLE pin, and an assertion enables the device until the pin is released. When the ENABLE_MASK bit is set to '1', the device does no longer react to the changing state of the pin as the ENABLE switch. OFF Requests An OFF request is used to orderly switch off the device. OFF requests initiate transition from any other mission state to the STANDBY state or the LP_STANDBY state depending on the setting of the LP_STANDBY_SEL bit. #GUID-117B0898-2FEC-4E9D-9F33-06019819BC63/SLVSEA7991 lists the conditions to generate the OFF requests and the corresponding destination state. OFF Requests EVENT DEBOUNCE LP_STANDBY_SEL BIT SETTING DESTINATION STATE nPWRON (pin) (long press key event) 8 s LP_STANDBY_SEL = 0 STANDBY LP_STANDBY_SEL = 1 LP_STANDBY ENABLE (pin) 8 µs LP_STANDBY_SEL = 0 STANDBY LP_STANDBY_SEL = 1 LP_STANDBY I2C_TRIGGER_0 NA LP_STANDBY_SEL = 0 STANDBY LP_STANDBY_SEL = 1 LP_STANDBY The long press key event occurs when the nPWRON pin stays low for longer than tLPK_TIME while the device is in a mission state. When the nPWRON or ENABLE pin is used as the OFF request, the device wakes up from the STANDBY or the LP_STANDBY state through the ON request initiated by the same pin. The NPWRON_START_MASK or the ENABLE_MASK must remain low in this case to allow the detection of the ON request initiated by the pin. If the device needs to enter the LP_STANDBY state through the OFF request, it is important that the state of the nPWRON or ENABLE pin must remain the same until the state transition is completed. Failure to do so may result in unsuccessful wake-up from the LP_STANDBY state when the pin re-initiates On request. Using the I2C_TRIGGER_0 bit as the OFF request enables the device to wake up from the STANDBY or the LP_STANDBY states through the detection of LP_WKUPn/WKUPn pins, as well as RTC alarm or timer interrupts. To enable this feature, the device must set the I2C_TRIGGER_0 bit to '1' while the NSLEEPn signals are masked, and the ON request (initialized by the nPWRON or ENABLE pins) must remain active. Also the interrupt bits ENABLE_INT, FSD_INT and the GPIOx_INT bits (for the GPIOx pins assigned as WKUP1 or WKUP2) must be cleared before setting the I2C_TRIGGER_0 bit to '1'. NSLEEP1 and NSLEEP2 Functions The SLEEP requests are activated through the assertion of nSLEEP1 or nSLEEP2 pins that are the secondary functions of the 11 GPIO pins. These pins can be selected through GPIO configuration using the GPIOx_SEL register bits. If the nSLEEP1 or nSLEEP2 pins are not available, the NSLEEP1B and NSLEEP2B register bits can be configured in place for their functions. The input of nSLEEP1 pin and the state of the NSLEEP1B register bit are combined to create the NSLEEP1 signal through an OR function. Similarly for the input of the nSLEEP2 pin and the NSLEEP2B register bit as they are combined to create the NSLEEP2 signal. A 1 → 0 logic level transition of the NSLEEP signal generates a sleep request, while a 0 → 1 logic level transition reverses the sleep request in the example PFSM from . When a NSLEEPn signal transitions from 1 → 0, it generates a sleep request to go from a higher power state to a lower power state. When the signal transitions from 0 → 1, it reverses the sleep request and returns the device to the higher power state. The NSLEEP1 signal is designed to control the SoC supply rails. The NSLEEP2 signal is designed to control the MCU supply rails. When NSLEEP1 signal changes from 1 → 0, depending on the state of NSLEEP2, the TPS6593-Q1 device exits ACTIVE state and enters either the MCU ONLY or the S2R states. When NSLEEP2 signal changes from 1 → 0, the device enters the S2R state regardless the state of NSLEEP1. When the NSLEEP2 input signal changes from 0 →1, the MCU supply rails are enabled and the device exits S2R state. Depending on the state of NSLEEP1 signal, the device enters either the MCU ONLY or the ACTIVE state. In order for the system to function correctly, the MCU rails must be enabled when the NSLEEP1 input signal changes from 0 →1, which enables the SOC supply rails. NSLEEP1 0 →1 transition is ignored if NSLEEP2 is 0. The NSLEEPn_MASK bit can be used to mask the sleep request associated with the corresponding NSLEEPn signal. When the NSLEEPn_MASK = 1, the corresponding NSLEEPn signal is ignored. shows how the combination of the NSLEEPn signals and NSLEEPn_MASK bits creates triggers A/B/C/D to the FSM to control the power state of the device. The states of the resources during ACTIVE, SLEEP, and DEEP SLEEP/S2R states are defined in the LDOn_CTRL and BUCKn_CTRL registers. For each resource, a transition to the MCU ONLY or the DEEP SLEEP/S2R states is controlled by the FSM when the resource is associated to the SLEEP or DEEP SLEEP/S2R states. shows the corresponding state assignment based on the state of the NSLEEPn and their corresponding mask signals using the example PFSM from .

Any one of these GPIO pins when configured as an input pin can be configured to wake up the device by setting GPIOn_SEL bit to select the WKUP1 or WKUP2 functions. In the example PFSM depicted in , when a GPIO pin is configured as a WKUP1 pin, a rising or falling edge detected at the input of this pin (configurable by the GPIOn_FALL_MASK and the GPIOn_RISE_MASK bits) wakes up the device to the ACTIVE state. Likewise if a GPIO pin is configured as a WKUP2 pin, a detected edge wakes up the device to the MCU ONLY state. If multiple edge detections of WKUP signals occur simultaneous, the device goes to the state in the following priority order: ACTIVE MCU ONLY When a valid edge is detected at a WKUP pin, the nINT pin generates an interrupt to signal the MCU of the wake-up event, and the GPIOx_INT interrupt bit is set. The wake request remains active until the GPIOx_INT bit is cleared by the MCU. While the wake request is executing, the device does not react to sleep requests to enter a lower power state until the corresponding GPIOx_INT interrupt bit is cleared to cancel the wake request. After the wake request is canceled, the device returns to the state indicated by the NSLEEP1 and NSLEEP2 signals as shown in . LP_WKUP Pins for Waking Up from LP STANDBY The LP_WKUP functions are activated through the edge detection of LP_WKUP pins, configurable as secondary functions of GPIO3 and GPIO4. They are specially designed to wake the device up from the LP STANDBY state when a high speed wake-up signal is detected. Similar to the WKUP1 and WKUP2 pins, when GPIO3 or GPIO4 pin is configured as an LP_WKUP1 pin, a rising or falling edge detected at the input of this pin (configurable by the GPIOn_FALL_MASK and the GPIOn_RISE_MASK bits) wakes up the device to the ACTIVE state. Likewise, if the pin is configured as an LP_WKUP2 pin, a detected edge wakes up the device to the MCU ONLY state. If multiple edge detections of LP_WKUP signals occur simultaneously, the device goes to the state in the following priority order: ACTIVE MCU ONLY Due to a digital control erratum in the device, the ENABLE_MASK/NPWRON_START_MASK bit must be set to '1' before the device enters LP_STANDBY state in order for the LP_WKUP2 pin to correctly wake up the device to the MCU_ONLY state. The TPS6593-Q1 device supports limited CAN wake-up capability through the LP_WKUP1/2 pins. When an input signal (without deglitch) with logic level transition from high-to-low or low-to-high with a minimum pulse width of tWK_PW_MIN is detected on the assigned LP_WKUP1/2 pins, the device wakes up asynchronously and executes the power up sequence. CAN-transceiver RXD- or INH-outputs can be connected to the LP_WKUP pin. If RXD-output is used, it is assumed that the transceiver RXD-pin IO is powered by the transceiver itself from an external supply when TPS6593-Q1 is in the LP_STANDBY state. If INH-signal is used it has to be scaled down to the recommenced GPIO input voltage level specified in the electrical characteristics table. In this PFSM example, the device can wake up from the LP_STANDBY state through the detection of LP_WKUP pins only if it enters the LP_STANDBY state through the TRIGGER_I2C_0 OFF request while the NSLEEPn signals are masked, and the on request initialized by the nPWRON/ENABLE pin remains active. Once a valid wake-up signal is detected at the LP_WKUP pin, it is handled as a WAKE request. The nINT pin generates an interrupt to signal the MCU of the wake-up event, and the corresponding GPIOx_INT interrupt bit is set. The wake request remains active until the interrupt bit is cleared by the MCU. shows how the device returns to the state indicated by the NSLEEP1 and NSLEEP2 signals after the wake request is canceled. illustrates the valid wake-up signal at the LP_WKUP1/2 pins, and the generation and clearing of the internal wake-up signal.

When this pin is configured as the nPWRON button, a short button press detection is latched internally as a device enable signal until the NPWRON_START_INT is cleared, or a long press key event is detected. The short button press detection occurs when an falling edge is detected at the nPWRON pin. When the NPWRON_START_MASK bit is set to '1', the device does no longer react to the changing state of the pin as the nPWRON press button.The nPWRON/ENABLE pin is a level sensitive pin when it is configured as an ENABLE pin, and an assertion enables the device until the pin is released. When the ENABLE_MASK bit is set to '1', the device does no longer react to the changing state of the pin as the ENABLE switch. OFF Requests An OFF request is used to orderly switch off the device. OFF requests initiate transition from any other mission state to the STANDBY state or the LP_STANDBY state depending on the setting of the LP_STANDBY_SEL bit. #GUID-117B0898-2FEC-4E9D-9F33-06019819BC63/SLVSEA7991 lists the conditions to generate the OFF requests and the corresponding destination state.

If the device needs to enter the LP_STANDBY state through the OFF request, it is important that the state of the nPWRON or ENABLE pin must remain the same until the state transition is completed. Failure to do so may result in unsuccessful wake-up from the LP_STANDBY state when the pin re-initiates On request.

Any one of these GPIO pins when configured as an input pin can be configured to wake up the device by setting GPIOn_SEL bit to select the WKUP1 or WKUP2 functions. In the example PFSM depicted in , when a GPIO pin is configured as a WKUP1 pin, a rising or falling edge detected at the input of this pin (configurable by the GPIOn_FALL_MASK and the GPIOn_RISE_MASK bits) wakes up the device to the ACTIVE state.

If multiple edge detections of WKUP signals occur simultaneous, the device goes to the state in the following priority order: ACTIVE MCU ONLY When a valid edge is detected at a WKUP pin, the nINT pin generates an interrupt to signal the MCU of the wake-up event, and the GPIOx_INT interrupt bit is set. The wake request remains active until the GPIOx_INT bit is cleared by the MCU. While the wake request is executing, the device does not react to sleep requests to enter a lower power state until the corresponding GPIOx_INT interrupt bit is cleared to cancel the wake request.

LP_WKUP Pins for Waking Up from LP STANDBY The LP_WKUP functions are activated through the edge detection of LP_WKUP pins, configurable as secondary functions of GPIO3 and GPIO4. They are specially designed to wake the device up from the LP STANDBY state when a high speed wake-up signal is detected. Similar to the WKUP1 and WKUP2 pins, when GPIO3 or GPIO4 pin is configured as an LP_WKUP1 pin, a rising or falling edge detected at the input of this pin (configurable by the GPIOn_FALL_MASK and the GPIOn_RISE_MASK bits) wakes up the device to the ACTIVE state.

If multiple edge detections of LP_WKUP signals occur simultaneously, the device goes to the state in the following priority order: ACTIVE MCU ONLY Due to a digital control erratum in the device, the ENABLE_MASK/NPWRON_START_MASK bit must be set to '1' before the device enters LP_STANDBY state in order for the LP_WKUP2 pin to correctly wake up the device to the MCU_ONLY state. The TPS6593-Q1 device supports limited CAN wake-up capability through the LP_WKUP1/2 pins. When an input signal (without deglitch) with logic level transition from high-to-low or low-to-high with a minimum pulse width of tWK_PW_MIN is detected on the assigned LP_WKUP1/2 pins, the device wakes up asynchronously and executes the power up sequence. CAN-transceiver RXD- or INH-outputs can be connected to the LP_WKUP pin. If RXD-output is used, it is assumed that the transceiver RXD-pin IO is powered by the transceiver itself from an external supply when TPS6593-Q1 is in the LP_STANDBY state. If INH-signal is used it has to be scaled down to the recommenced GPIO input voltage level specified in the electrical characteristics table. In this PFSM example, the device can wake up from the LP_STANDBY state through the detection of LP_WKUP pins only if it enters the LP_STANDBY state through the TRIGGER_I2C_0 OFF request while the NSLEEPn signals are masked, and the on request initialized by the nPWRON/ENABLE pin remains active. Once a valid wake-up signal is detected at the LP_WKUP pin, it is handled as a WAKE request.

CAN Wake-Up Timing Diagram CAN Wake-Up Timing Diagram Error Handling Operations The FSM engine of the TPS6593-Q1 device is designed to handle the following types of errors throughout the operation: Power Rail Output Error Boot BIST Error Runtime BIST Error Catastrophic Error Watchdog Error Error Signal Monitor (ESM) Error Warnings Power Rail Output Error A power rail output error occurs when an error condition is detected on the output rails of the device that are used to power the attached MCU or SoC. These errors include the following: Rails not reaching or maintaining within the power good voltage level threshold. A short condition that is detected at a regulator output. The load current that exceeds the forward current limit. The BUCKx_GRP_SEL, LDOn_GRP_SEL and VCCA_GRP_SEL registers are used to configure the rail group for all of the Bucks, LDOs, and the voltage monitors that are available for external rails. The selectable rail groups are MCU rail group, SoC rail group, or OTHER rail group. The TPS6593-Q1 device is designed to react differently when an error is detected from a power resource assigned to the different rail groups. shows how the SOC_RAIL_TRIG[1:0], MCU_RAIL_TRIG[1:0], and OTHER_RAIL_TRIG[1:0] register bits are used as the Immediate Shutdown Trigger Mask, Orderly Shutdown Trigger Mask, MCU Power Error Trigger Mask, or the SoC Power Error Trigger Mask. The settings of these register bits determine the error handling sequence that the assigned groups of rails perform in case of an output error. The PFSM engine can be configured to execute the appropriate error handling sequence for the following error handling sequence options: immediate shutdown, orderly shutdown, MCU power error, or SOC power error. For example, if an immediate shutdown sequence is assigned to the MCU rail group through the MCU_RAIL_TRIG[1:0] register bits, any failure detected in this group of rails causes the IMMEDIATE_SHUTDOWN trigger to be executed. This trigger is expected to start the immediate shutdown sequence and cause the device to enter the SAFE RECOVERY state. The device immediately resets the attached MCU and SoC by driving the nRSTOUT and nRSTOUT_SoC (GPO1 or GPIO11) pins low. All of the power resources assigned to the MCU and SOC shut down immediately without a sequencing order. The nINT pin signals that an MCU_PWR_ERR_INT interrupt event has occurred and the EN_DRV pin is forced low. If the error is recoverable within the recovery time interval, the device increments the recovery count, returns to INIT state, and reattempts the power up sequence (if the recovery count has not exceeded the counter threshold). If the recovery count has already exceeded the threshold, the device stays in the SAFE RECOVERY state until VCCA voltage is below the VCCA_UVLO threshold and the device is power-cycled. The power resources assigned to the SoC rail group are typically assigned to the SOC power error handling sequence. In this PFSM example depicted in , when a power resource in this group is detected, the PFSM typically causes the device to execute the shutdown of all the resources assigned to the SoC rail group, and the device enters the MCU ONLY state. The device immediately resets the attached SoC by toggling the nRSTOUT_SoC (GPO1 or GPIO11) pin. The reset output to the MCU and the resources assigned to the MCU rail group remain unchanged. The EN_DRV pin also remains unchanged, and the nINT pin signals that an SOC_PWR_ERR_INT interrupt event has occurred. To recover from the MCU_ONLY state after a SOC power error, the MCU software must set NSLEEP1 signal to '0' while NSLEEP2 signal remains '1'. This action signals TPS6593-Q1 that MCU has acknowledged the SOC power error, and is ready to return to normal operation. MCU can then set the NSLEEP1 signal back to '1' for the device to return to ACTIVE state and reattempt the SoC power up. Refer to for information regarding the setting of the NSLEEP1 and NSLEEP2 signals. The power resources used for peripheral devices in the system, for which no error-handling action is required, the rail mapping needs to be selected as "no group assigned". Catastrophic Error Catastrophic errors are errors that affect multiple power resources such as errors detected in supply voltage, LDOVINT supply for control logic, errors on internal clock signals, device temperature passing the thermal shutdown threshold, error detected on the SPMI bus, or an error detected in the PFSM sequence. Following errors are grouped as severe errors: VCCA > OVP threshold Junction temperature > immediate shutdown level Error in PFSM Sequence For these above listed errors, depending on the setting of bits SEVERE_ERR_TRIG[1:0], an immediate or orderly shutdown condition is created. The PFSM executes the corresponding sequence for the IMMEDIATE_SHUTDOWN trigger or the ORDERLY_SHUTDOWN trigger and enters the SAFE RECOVERY state. Following errors are grouped as moderate errors: Junction temperature > orderly shutdown level BIST failure CRC error in register map Recovery counter exceeding the threshold value Error on SPMI bus Readback error on nRSTOUT pin or nINT pin For these above listed errors, depending on the setting of bits MODERATE_ERR_TRIG[1:0], an immediate or orderly shutdown condition is created. The PFSM executes the corresponding sequence for the IMMEDIATE_SHUTDOWN trigger or the ORDERLY_SHUTDOWN trigger and enters the SAFE RECOVERY state. For following errors, the device performs an immediate shutdown and resets all internal logic circuits: VCCA < UVLO threshold Error on LDOVINT supply Errors on internal clock signals Unrecoverable CRC error in the SRAM memory of the PFSM For all of the above listed errors, the device resets the attached MCU and SoC by driving the nRSTOUT and the GPIO pin used as nRSTOUT_SoC (GPO1 or GPIO11) pins low. All of the power resources assigned to the attached MCUand SOC are shut down. The nINT pin is driven low to signal an interrupt event has occurred, and the EN_DRV pin is forced low. Watchdog (WDOG) Error Watchdog (WDOG) describes details about the Watchdog (WDOG) errors detection mechanisms. Warnings Warning are non-catastrophic errors. When such an error occurs while the device is in the operating states, the device detects the error and handles the error through the interrupt handler. These are errors such as thermal warnings, I2C, or SPI communication errors, or power resource current limit detection while the output voltage still maintains within the power good threshold. When these errors occur, the nINT pin is driven low to signal an interrupt event has occurred. The device remains in the operation state and the state of the EN_DRV pin, the power resources, and the reset outputs remain unchanged. The power resource current limit detection can, by setting bit EN_ILIM_FSM_CTRL=1, be configured such that it is handled as a Power Rail Output Error as described in .

The load current that exceeds the forward current limit. The BUCKx_GRP_SEL, LDOn_GRP_SEL and VCCA_GRP_SEL registers are used to configure the rail group for all of the Bucks, LDOs, and the voltage monitors that are available for external rails. The selectable rail groups are MCU rail group, SoC rail group, or OTHER rail group. The TPS6593-Q1 device is designed to react differently when an error is detected from a power resource assigned to the different rail groups. shows how the SOC_RAIL_TRIG[1:0], MCU_RAIL_TRIG[1:0], and OTHER_RAIL_TRIG[1:0] register bits are used as the Immediate Shutdown Trigger Mask, Orderly Shutdown Trigger Mask, MCU Power Error Trigger Mask, or the SoC Power Error Trigger Mask. The settings of these register bits determine the error handling sequence that the assigned groups of rails perform in case of an output error. The PFSM engine can be configured to execute the appropriate error handling sequence for the following error handling sequence options: immediate shutdown, orderly shutdown, MCU power error, or SOC power error. For example, if an immediate shutdown sequence is assigned to the MCU rail group through the MCU_RAIL_TRIG[1:0] register bits, any failure detected in this group of rails causes the IMMEDIATE_SHUTDOWN trigger to be executed. This trigger is expected to start the immediate shutdown sequence and cause the device to enter the SAFE RECOVERY state. The device immediately resets the attached MCU and SoC by driving the nRSTOUT and nRSTOUT_SoC (GPO1 or GPIO11) pins low. All of the power resources assigned to the MCU and SOC shut down immediately without a sequencing order. The nINT pin signals that an MCU_PWR_ERR_INT interrupt event has occurred and the EN_DRV pin is forced low. If the error is recoverable within the recovery time interval, the device increments the recovery count, returns to INIT state, and reattempts the power up sequence (if the recovery count has not exceeded the counter threshold). If the recovery count has already exceeded the threshold, the device stays in the SAFE RECOVERY state until VCCA voltage is below the VCCA_UVLO threshold and the device is power-cycled. The power resources assigned to the SoC rail group are typically assigned to the SOC power error handling sequence. In this PFSM example depicted in , when a power resource in this group is detected, the PFSM typically causes the device to execute the shutdown of all the resources assigned to the SoC rail group, and the device enters the MCU ONLY state. The device immediately resets the attached SoC by toggling the nRSTOUT_SoC (GPO1 or GPIO11) pin. The reset output to the MCU and the resources assigned to the MCU rail group remain unchanged. The EN_DRV pin also remains unchanged, and the nINT pin signals that an SOC_PWR_ERR_INT interrupt event has occurred. To recover from the MCU_ONLY state after a SOC power error, the MCU software must set NSLEEP1 signal to '0' while NSLEEP2 signal remains '1'. This action signals TPS6593-Q1 that MCU has acknowledged the SOC power error, and is ready to return to normal operation. MCU can then set the NSLEEP1 signal back to '1' for the device to return to ACTIVE state and reattempt the SoC power up. Refer to for information regarding the setting of the NSLEEP1 and NSLEEP2 signals.

This feature is enabled by setting the FSD_MASK register bit to '0', and setting the NPWRON_SEL[1:0] registers bits to '10' or '11' to mask the functionality of the nPWRON/ENABLE pin. When the device is powered up from the NO SUPPLY state, the FSD detection is validated after the NVM default for this feature is loaded into the device memory. When the FSD feature is enabled, the PMIC immediately powers up from the NO SUPPLY state to an operation state, configured by the STARTUP_DEST[1:0] bits when VCCA > VCCA_UV, while VCCA_UV gating is performed, and only when VCCA voltage monitoring is enabled (VCCA_VMON_EN = 1). After the device arrives the corresponding STARTUP_DEST[1:0] operation state, the MCU must setup the NSLEEP1 and NSLEEP2 signals accordingly before clearing the FSD_INT interrupt.

This feature is enabled by setting the FSD_MASK register bit to '0', and setting the NPWRON_SEL[1:0] registers bits to '10' or '11' to mask the functionality of the nPWRON/ENABLE pin. When the device is powered up from the NO SUPPLY state, the FSD detection is validated after the NVM default for this feature is loaded into the device memory. When the FSD feature is enabled, the PMIC immediately powers up from the NO SUPPLY state to an operation state, configured by the STARTUP_DEST[1:0] bits when VCCA > VCCA_UV, while VCCA_UV gating is performed, and only when VCCA voltage monitoring is enabled (VCCA_VMON_EN = 1).

This feature consolidates and simplifies the IO control signals required between the application processor or the microcontroller and multiple PMICs in the system. The control interface consists of an SPMI protocol that communicates the next power state information from the primary PMIC to up to 5 secondary PMICs, and receives feedback signal from the secondary PMICs to indicate any error condition or power state information. is the block diagram of the power state synchronization scheme. The primary PMIC in this block diagram is responsible for broadcasting the synchronous system power state data, and processing the error feedback signals from the secondary PMICs. The primary PMIC is the controller device on the SPMI bus, and the secondary PMICs are the target devices on the SPMI bus. Multi-PMIC Power State Synchronization Block Diagram In this scheme, each primary and secondary PMIC runs on its own system clock, and maintains its own register map. Each PMIC monitors its own activities and pulls down the open-drain output of nINT or PGOOD pin when errors are detected. The microprocessor must read the status bits from each PMIC device through the I2C or SPI interface to find out the source of the error that is reported. To synchronize the timing when entering and exiting from the LP_STANDBY state, the VOUT_LDOVINT of the TPS6593-Q1 device must be connected to the ENABLE input of the secondary PMICs, which are the target devices in the SPMI interface bus. illustrates the pin connections between the primary, the secondary, and the application processor or the System-on-Chip. Multi-PMIC Pin Connections The power sequencer of the multiple PMICs are synchronized at the beginning of each power up and power down sequence; a variation in the sequence timing, however, is still possible due to the ±5% clock accuracy of the independent system clocks on the primary and secondary PMICs. The worst-case sequence timing variation from different PMIC rails is up to ±10% of the target delay time. illustrates the creation of this timing variation between PMICs. Multi-PMIC Rail Sequencing Timing Variation SPMI Interface System Setup An SPMI interface in the TPS6593-Q1 device is utilized to communicate the power state transition across multiple PMICs in the system. The SPMI interface contains a controller block and a target block. There is only one PMIC, which is the primary PMIC, that acts as SPMI controller in any given system. As the SPMI controller it initiates SPMI interface BIST and executes periodic checking of the SPMI bus health. The primary PMIC has a controller-ID (CID)= 1. The target block of SPMI interface in the primary PMIC device is activated as well, in order to receive SPMI communication messages from the secondary PMICs. The primary PMIC has a target-ID (TID) = 0101. Each secondary PMIC on the SPMI network only has the target block of its SPMI interface enabled. There cannot be more than five secondary PMICs in the system. The target-IDs (TIDs) for the five secondary PMICs are: 1st target device: 0011 2nd target device: 1100 3rd target device: 1001 4th target device: 0110 5th target device: 1010 All devices in the SPMI network listen to the group target-ID (GTID): 1111. This address is used to communicate all power state transition information in broadcast mode to all connected devices on the SPMI bus. Transmission Protocol and CRC The communication between the devices on the network utilizes Extended Register Write command to GTID address 1111 with byte length of 2. Sequence format complies with MIPI SPMI 2.0 specification. First data frame carries the data payload of 5 bits and 3 filler bits. Communication over the SPMI interface may contain information regarding the power state transition or the unique TID of one or more target devices. In the case of power state information, the data payload contains 5 bits of Trigger ID information and 3 trigger state bits. In the case of TID information, all 8 bits contain the TID of the target device. Second data frame carries 8 bits of CRC information. CRC polynomial used is X8 + X2 + X + 1. CRC is calculated over the SPMI command frame, the address frame, and the first data frame (which contains the payload and excludes the parity bits in these three frames). shows the data format of the SPMI Extended Register Write Command. SPMI Extended Register Write Command Operation with Transmission Errors If the receiving device detects a parity or CRC error in the incoming sequence it responds with negative ACK/NACK per SPMI standard. If the transmitting device sees NACK response, it tries to resend the message as many times as indicated by SPMI_RETRY_LIMIT register bits. After that it considers the SPMI bus inoperable, sets SPMI_ERR_INT interrupt and goes to the safe recovery state and executes an orderly shutdown. Bus arbitration requests do not count as failed attempts if a target device loses bus arbitration. SPMI_RETRY_LIMIT counter is reset after each successful transmission by the device. If a target device has determined that SPMI does not work reliably it does not respond to any SPMI commands anymore until power-on-reset event has occurred. This "no-response" behavior is to prevent continued operation in a situation where SPMI is unreliable. If a target device does no longer respond to any SPMI command, the controller device on the SPMI bus detects a missing target device on the network during the periodic testing of SPMI bus. The target device then internally handles the SPMI error condition per error handling rules set for the device (in general executing an orderly shutdown). SPMI block signals to the device that SPMI bus error has occurred after the retry limit has been exceeded. Transmitted Information The SPMI bus is used to carry two types of information: PFSM Trigger ID between the SPMI controller and target devices TID from SPMI target devices to SPMI controller device The SPMI controller device reads the TID of the target devices periodically to check the health of the interface. Exchanging Trigger IDs for the power state transition is sufficient to keep the PFSMs of all the devices on the SPMI network in synchronization. Device interrupts explain reason for the power state transitions. SPMI Target Device Communication to SPMI Controller Device An SPMI target device communicates to the SPMI controller device and any other SPMI target devices, only if there is an internal error that is not SPMI related. The target device initiates the error communication using Arbitration Request with A-bit as defined in the SPMI 2.0 specification. SPMI 2.0 protocol manages the situation with multiple target devices requesting error communication at the same time, by using the target arbitration process as described in SPMI 2.0 specification. Once the SPMI target device wins the arbitration using the A-bit protocol, it performs an Extended Register Write command to Group Target ID (GTID) address 1111 by using the protocol described in for communicating PFSM trigger ID. Incomplete Communication from SPMI Target Device to SPMI Controller Device In case the SPMI controller device detects an arbitration request on the SPMI interface, but the received sequence has an error or is incomplete, the SPMI controller device immediately performs the SPMI Built-In Self-Test (SPMI-BIST). If this SPMI-BIST fails, the SPMI controller device executes the error handling for the SPMI error. If the SPMI-BIST passes successfully, the SPMI controller device resumes normal operation. SPMI-BIST Overview The SPMI-BIST is performed during BIST state and regularly during runtime operation. below illustrates how the SPMI-BIST operates during device power-up. SPMI-BIST Operation After the input power is detected and verified to be at the correct level, the TPS6593-Q1 initializes itself by reading the NVM and performs all actions that are needed to prepare for operation. After this initialization, the TPS6593-Q1 enters the BOOT BIST state, in which the internal logic performs a series of tests to verify that the TPS6593-Q1 device is OK. As part of this test, the SPMI- BIST is performed. After it is completed successfully, the TPS6593-Q1 device goes to the standby state and waits for further signals from the system to initiate the power-up sequence of the processor. A valid on request initiates the processor power-up sequence. The controller device communicates this event through the SPMI bus to all of the target devices. After that, the power-up sequence is executed and TPS6593-Q1 enters the configured mission state. SPMI Bus during Boot BIST and RUNTIME BIST During Boot BIST and RUNTIME BIST, both the Logic BIST (LBIST) on the SPMI logic and the SPMI-BIST are performed to check correct operation of the SPMI bus. The LBIST is performed first before the SPMI-BIST during BOOT BIST and RUNTIME BIST. The SPMI-BIST is implemented by reading TID from each target device on the SPMI bus into the controller device, and ensuring they are unique and match the expected amount of target devices. This process of checking the TID of each target device ensures that: All SPMI target devices are present in the system as expected The SPMI logic blocks are working on the SPMI controller device and all of the SPMI target devices The pins and wires on the ICs and PCB are in working order The SPMI-BIST is initiated by the SPMI controller block in the primary PMIC by writing a request to all SPMI target device(s) (using GTID) to send their TIDs to the SPMI controller block of the primary PMIC. Upon receiving this command from the SPMI controller device, the SPMI target devices request SPMI bus arbitration using the SR-bit protocol. Upon winning the bus arbitration the SPMI target devices transmit their TID into the SPMI target block of the primary PMIC. The SPMI controller block of the primary PMIC contains a list of all SPMI target device(s) on the SPMI bus and their TIDs in the register set. The SPMI controller block of the primary PMIC reads the TID from each SPMI target device and compares the result with the stored TID for the corresponding SPMI target device. The SPMI controller device has to ensure that every non-zero TID on its list is returned, in order to support use cases in which there are two or more identical SPMI target devices, with same TID, in the system. In these cases, it is mandatory that the expected number of the same TIDs is returned. If no identical PMICs are to be used, then a return of the same TID multiple times is an error due to incorrect assembly of identical PMICs onto the PCB. An all-zero TID stored in the list of the primary PMIC indicates that there are no SPMI target device(s) present on the SPMI Bus. Periodic Checking of the SPMI The SPMI controller block in the primary PMIC executes the SPMI-BIST periodically while device is operating. The time-period after the SPMI-BIST is repeated according factory-configured settings during the device boot time, and after the device reaches mission states. The factory-configured settings of this SPMI-BIST time period must be the same for all PMICs on the same SPMI network. The SPMI target devices on the SPMI bus expect a request for sending its TID from the SPMI controller device within 1.5x the factory-configured period . This factor 1.5x provides enough margin for clock uncertainty between the SPMI controller device and the SPMI target device. During mission state operation, the SPMI controller device expects the SPMI target devices to respond to the TID request within the factory-configured polling time-out period . In other words, from the polling start command each SPMI target device must respond within this factory-configured time interval. During boot time or when the device enters Safe Recovery state, to prevent the SPMI controller device from polling the SPMI target devices too often while one or more of these recovering from a system error such as a thermal shutdown event, the device sets a longer timeout period that allows the SPMI target devices to respond to the SPMI controller device before he SPMI controller device reports an error. If one or more devices on the SPMI bus cause a violating of the polling time-out period either during start-up or during normal operation, the SPMI controller block in the affected PMIC(s) sets a SPMI error trigger signal to the PFSM of the affected PMIC(s), causing a complete shutdown of the affected PMIC(s). As a result, the affected PMIC(s) no longer respond on the SPMI bus, which in turn is detected by the SPMI controller block off the non-affected PMICs on the SPMI bus. The SPMI controller block in these PMICs sets an SPMI error to the PFSM in these PMICs, causing a complete shutdown of these PMICs. Therefore, all PMICs are finally shutdown if one or more devices on the SPMI bus cause a violating of the polling time-out period . SPMI Message Priorities The SPMI Bus uses the protocol priority levels listed in #GUID-F91E50E4-0CEA-4F17-B748-4E3A03F33999/SLVSE824332 for each type of communication message.

SPMI Extended Register Write Command Operation with Transmission Errors If the receiving device detects a parity or CRC error in the incoming sequence it responds with negative ACK/NACK per SPMI standard. If the transmitting device sees NACK response, it tries to resend the message as many times as indicated by SPMI_RETRY_LIMIT register bits.

If a target device has determined that SPMI does not work reliably it does not respond to any SPMI commands anymore until power-on-reset event has occurred. This "no-response" behavior is to prevent continued operation in a situation where SPMI is unreliable.

SPMI Target Device Communication to SPMI Controller Device An SPMI target device communicates to the SPMI controller device and any other SPMI target devices, only if there is an internal error that is not SPMI related. The target device initiates the error communication using Arbitration Request with A-bit as defined in the SPMI 2.0 specification.

SPMI-BIST Overview The SPMI-BIST is performed during BIST state and regularly during runtime operation. below illustrates how the SPMI-BIST operates during device power-up. SPMI-BIST Operation After the input power is detected and verified to be at the correct level, the TPS6593-Q1 initializes itself by reading the NVM and performs all actions that are needed to prepare for operation. After this initialization, the TPS6593-Q1 enters the BOOT BIST state, in which the internal logic performs a series of tests to verify that the TPS6593-Q1 device is OK. As part of this test, the SPMI- BIST is performed. After it is completed successfully, the TPS6593-Q1 device goes to the standby state and waits for further signals from the system to initiate the power-up sequence of the processor. A valid on request initiates the processor power-up sequence. The controller device communicates this event through the SPMI bus to all of the target devices. After that, the power-up sequence is executed and TPS6593-Q1 enters the configured mission state. SPMI Bus during Boot BIST and RUNTIME BIST During Boot BIST and RUNTIME BIST, both the Logic BIST (LBIST) on the SPMI logic and the SPMI-BIST are performed to check correct operation of the SPMI bus. The LBIST is performed first before the SPMI-BIST during BOOT BIST and RUNTIME BIST. The SPMI-BIST is implemented by reading TID from each target device on the SPMI bus into the controller device, and ensuring they are unique and match the expected amount of target devices. This process of checking the TID of each target device ensures that: All SPMI target devices are present in the system as expected The SPMI logic blocks are working on the SPMI controller device and all of the SPMI target devices The pins and wires on the ICs and PCB are in working order The SPMI-BIST is initiated by the SPMI controller block in the primary PMIC by writing a request to all SPMI target device(s) (using GTID) to send their TIDs to the SPMI controller block of the primary PMIC. Upon receiving this command from the SPMI controller device, the SPMI target devices request SPMI bus arbitration using the SR-bit protocol. Upon winning the bus arbitration the SPMI target devices transmit their TID into the SPMI target block of the primary PMIC. The SPMI controller block of the primary PMIC contains a list of all SPMI target device(s) on the SPMI bus and their TIDs in the register set. The SPMI controller block of the primary PMIC reads the TID from each SPMI target device and compares the result with the stored TID for the corresponding SPMI target device. The SPMI controller device has to ensure that every non-zero TID on its list is returned, in order to support use cases in which there are two or more identical SPMI target devices, with same TID, in the system. In these cases, it is mandatory that the expected number of the same TIDs is returned. If no identical PMICs are to be used, then a return of the same TID multiple times is an error due to incorrect assembly of identical PMICs onto the PCB. An all-zero TID stored in the list of the primary PMIC indicates that there are no SPMI target device(s) present on the SPMI Bus. Periodic Checking of the SPMI The SPMI controller block in the primary PMIC executes the SPMI-BIST periodically while device is operating. The time-period after the SPMI-BIST is repeated according factory-configured settings during the device boot time, and after the device reaches mission states. The factory-configured settings of this SPMI-BIST time period must be the same for all PMICs on the same SPMI network. The SPMI target devices on the SPMI bus expect a request for sending its TID from the SPMI controller device within 1.5x the factory-configured period . This factor 1.5x provides enough margin for clock uncertainty between the SPMI controller device and the SPMI target device. During mission state operation, the SPMI controller device expects the SPMI target devices to respond to the TID request within the factory-configured polling time-out period . In other words, from the polling start command each SPMI target device must respond within this factory-configured time interval. During boot time or when the device enters Safe Recovery state, to prevent the SPMI controller device from polling the SPMI target devices too often while one or more of these recovering from a system error such as a thermal shutdown event, the device sets a longer timeout period that allows the SPMI target devices to respond to the SPMI controller device before he SPMI controller device reports an error. If one or more devices on the SPMI bus cause a violating of the polling time-out period either during start-up or during normal operation, the SPMI controller block in the affected PMIC(s) sets a SPMI error trigger signal to the PFSM of the affected PMIC(s), causing a complete shutdown of the affected PMIC(s). As a result, the affected PMIC(s) no longer respond on the SPMI bus, which in turn is detected by the SPMI controller block off the non-affected PMICs on the SPMI bus. The SPMI controller block in these PMICs sets an SPMI error to the PFSM in these PMICs, causing a complete shutdown of these PMICs. Therefore, all PMICs are finally shutdown if one or more devices on the SPMI bus cause a violating of the polling time-out period . SPMI Message Priorities The SPMI Bus uses the protocol priority levels listed in #GUID-F91E50E4-0CEA-4F17-B748-4E3A03F33999/SLVSE824332 for each type of communication message.

SPMI-BIST Operation After the input power is detected and verified to be at the correct level, the TPS6593-Q1 initializes itself by reading the NVM and performs all actions that are needed to prepare for operation. After this initialization, the TPS6593-Q1 enters the BOOT BIST state, in which the internal logic performs a series of tests to verify that the TPS6593-Q1 device is OK. As part of this test, the SPMI- BIST is performed. After it is completed successfully, the TPS6593-Q1 device goes to the standby state and waits for further signals from the system to initiate the power-up sequence of the processor. A valid on request initiates the processor power-up sequence. The controller device communicates this event through the SPMI bus to all of the target devices. After that, the power-up sequence is executed and TPS6593-Q1 enters the configured mission state. The SPMI-BIST is performed during BIST state and regularly during runtime operation. below illustrates how the SPMI-BIST operates during device power-up.

The LBIST is performed first before the SPMI-BIST during BOOT BIST and RUNTIME BIST. The SPMI-BIST is implemented by reading TID from each target device on the SPMI bus into the controller device, and ensuring they are unique and match the expected amount of target devices. This process of checking the TID of each target device ensures that: All SPMI target devices are present in the system as expected The SPMI logic blocks are working on the SPMI controller device and all of the SPMI target devices The pins and wires on the ICs and PCB are in working order The SPMI-BIST is initiated by the SPMI controller block in the primary PMIC by writing a request to all SPMI target device(s) (using GTID) to send their TIDs to the SPMI controller block of the primary PMIC. Upon receiving this command from the SPMI controller device, the SPMI target devices request SPMI bus arbitration using the SR-bit protocol. Upon winning the bus arbitration the SPMI target devices transmit their TID into the SPMI target block of the primary PMIC. The SPMI controller block of the primary PMIC contains a list of all SPMI target device(s) on the SPMI bus and their TIDs in the register set. The SPMI controller block of the primary PMIC reads the TID from each SPMI target device and compares the result with the stored TID for the corresponding SPMI target device. The SPMI controller device has to ensure that every non-zero TID on its list is returned, in order to support use cases in which there are two or more identical SPMI target devices, with same TID, in the system. In these cases, it is mandatory that the expected number of the same TIDs is returned. If no identical PMICs are to be used, then a return of the same TID multiple times is an error due to incorrect assembly of identical PMICs onto the PCB. An all-zero TID stored in the list of the primary PMIC indicates that there are no SPMI target device(s) present on the SPMI Bus.

Periodic Checking of the SPMI The SPMI controller block in the primary PMIC executes the SPMI-BIST periodically while device is operating. The time-period after the SPMI-BIST is repeated according factory-configured settings during the device boot time, and after the device reaches mission states. The factory-configured settings of this SPMI-BIST time period must be the same for all PMICs on the same SPMI network. The SPMI target devices on the SPMI bus expect a request for sending its TID from the SPMI controller device within 1.5x the factory-configured period . This factor 1.5x provides enough margin for clock uncertainty between the SPMI controller device and the SPMI target device. During mission state operation, the SPMI controller device expects the SPMI target devices to respond to the TID request within the factory-configured polling time-out period . In other words, from the polling start command each SPMI target device must respond within this factory-configured time interval.

For SPI, changed all instances of legacy terminology into "controller" and "peripheral". For the CRC, changed all instances of legacy terminology into "CRC on received data (R_CRC)", and "CRC on transmitted data" (T_CRC). These changes also applies to all sub-sections.yes The device has two, exclusive selectable (from factory settings) interfaces. Please refer to the user's guide of the orderable part number which option has been selected. The first selection is up to two high-speed I2C interfaces. The second selection is one SPI interface. The SPI and I2C1 interfaces are used to fully control and configure the device, and have access to all of the configuration registers and Watchdog registers. During normal operating mode, when the I2C configuration is selected, and the GPIO1 and GPIO2 pins are configured as the SCL_I2C2 and SDA_I2C2 pins, the I2C2 interface becomes the dedicated interface for the Q&A Watchdog communication channel, while I2C1 interface no longer has access to the Watchdog registers. . CRC Calculation for I2C and SPI Interface Protocols A 20220110 Corrected figure on Calculation of 8-Bit Controller CRC (R_CRC) Output, corrected figure on Calculation of 8-Bit Target CRC (T_CRC) Inputyes For safety applications, the TPS6593-Q1 supports read and write protocols with embedded CRC data fields. The TPS6593-Q1 uses a standard CRC-8 polynomial to calculate the checksum value: X8 + X2 + X + 1. The CRC algorithm details are as follows: Initial value for the remainder is all 1s Big-endian bit stream order Result inversion is not applied For I2C Interface, the TPS6593-Q1 uses the above mentioned CRC-8 polynomial to calculate the checksum value on every bit except the ACK and NACK bits it receives from the MCU during a write protocol. The TPS6593-Q1 compares this calculated checksum with the R_CRC checksum value that it receives from the MCU. The TPS6593-Q1 also uses the above mentioned CRC-8 polynomial to calculate the T_CRC checksum value during a read protocol. This T_CRC checksum value is based on every bit that the TPS6593-Q1 receives, except the ACK and NACK bits, and the data that the TPS6593-Q1 transmits to the MCU during a read protocol. The MCU must use this same CRC-8 polynomial to calculate the checksum value based on the bits that the MCU receives from the TPS6593-Q1. The MCU must compare this calculated checksum with the T_CRC checksum value that it receives from the TPS6593-Q1. For the SPI interface, the TPS6593-Q1 uses the above mentioned CRC-8 polynomial to calculate the checksum value on every bit it receives from the MCU during a write protocol. The TPS6593-Q1 compares this calculated checksum with the R_CRC checksum value, that it receives from the MCU. During a read protocol, the device also uses the above mentioned CRC-8 polynomial to calculate the T_CRC checksum value based on the first 16 bits sent by the MCU, and the next 8 bits the TPS6593-Q1 transmits to the MCU. The MCU must use this same CRC-8 polynomial to calculate the checksum value based on the bits which the MCU sends to and receives from the TPS6593-Q1, and compare it with the T_CRC checksum value that it receives from the TPS6593-Q1. and are examples for the 8-bit R_CRC and the T_CRC calculation from 16-bit databus. Calculation of 8-Bit CRC on Received Data (R_CRC) Calculation of 8-Bit CRC on Transmitted Data (T_CRC) I2C-Compatible Interface The default I2C1 7-bit device address of the TPS6593-Q1 device is set to a binary value that is described in the user's guide of the orderable part number of the TPS6593-Q1 PMIC, while the two least-significant bits can be changed for alternative page selection listed under . The default 7-bit device address for the I2C2 interface, for accessing the watchdog configuration registers and for operating the watchdog in Q&A mode, is described in the user's guide of the orderable part number of the TPS6593-Q1 PMIC. The I2C-compatible synchronous serial interface provides access to the configurable functions and registers on the device. This protocol uses a two-wire interface for bidirectional communications between the devices connected to the bus. The two interface lines are the serial data line (SDA), and the serial clock line (SCL). Every device on the bus is assigned a unique address and acts as either a controller or a target depending on whether it generates or receives the serial clock SCL. The SCL and SDA lines must each have a pullup resistor placed somewhere on the line and remain HIGH even when the bus is idle. The device supports standard mode (100 kHz), fast mode (400 kHz), and fast mode plus (1 MHz) when VIO is 3.3 V or 1.8 V, and high-speed mode (3.4 MHz) only when VIO is 1.8 V. Data Validity The data on the SDA line must be stable during the HIGH period of the clock signal (SCL). In other words, the state of the data line can only be changed when clock signal is LOW. Data Validity Diagram Start and Stop Conditions The device is controlled through an I2C-compatible interface. START and STOP conditions classify the beginning and end of the I2C session. A START condition is defined as the SDA signal going from HIGH to LOW while the SCL signal is HIGH. A STOP condition is defined as the SDA signal going from LOW to HIGH while the SCL signal is HIGH. The I2C controller device always generates the START and STOP conditions. Start and Stop Sequences The I2C bus is considered busy after a START condition and free after a STOP condition. The I2C controller device can generate repeated START conditions during data transmission. A START and a repeated START condition are equivalent function-wise. shows the SDA and SCL signal timing for the I2C-compatible bus. For timing values, see the Specification section. I2C-Compatible Timing Transferring Data Every byte put on the SDA line must be eight bits long, with the most significant bit (MSB) being transferred first. Each byte of data has to be followed by an acknowledge bit. The acknowledge related clock pulse is generated by the controller device. The controller device releases the SDA line (HIGH) during the acknowledge clock pulse. The device pulls down the SDA line during the 9th clock pulse, signifying an acknowledge. The device generates an acknowledge after each byte has been received. There is one exception to the acknowledge after every byte rule. When the controller device is the receiver, it must indicate to the transmitter an end of data by not-acknowledging (negative acknowledge) the last byte clocked out of the target device. This negative acknowledge still includes the acknowledge clock pulse (generated by the controller device), but the SDA line is not pulled down. After the START condition, the bus controller device sends a chip address. This address is seven bits long followed by an eighth bit which is a data direction bit (READ or WRITE). For the eighth bit, a 0 indicates a WRITE and a 1 indicates a READ. The second byte selects the register to which the data is written. The third byte contains data to write to the selected register. shows an example bit format of device address 110000-Bin = 60Hex. Example Device Address For safety applications, the device supports read and write protocols with embedded CRC data fields. In a write cycle, the I2C controller device (the MCU) must provide the 8-bit CRC value after sending the write data bits and receiving the ACK from the target (the TPS6593-Q1 PMIC). The CRC value must be calculated from every bit included in the write protocol except the ACK bits from the target. See CRC Calculation for I2C and SPI Interface Protocols. In a read cycle, the I2C target must provide the 8-bit CRC value after sending the read data bits and the ACK bit, and expect to receive the NACK from the controller at the end of the protocol. The CRC value must be calculated from every bit included in the read protocol except the ACK and NACK bits. See CRC Calculation for I2C and SPI Interface Protocols.If I2C CRC is enabled in the device and an I2C write without R_CRC bits is done, the device does not process the write request. The device does not set any interrupt bit and does not pull the nINT pin low. The embedded CRC field can be enabled or deactivated from the protocol by setting the I2C1_SPI_CRC_EN register bit to '1' - enabled, '0' - deactivated. The default of this bit is configurable through the NVM. In case the calculated CRC-value does not match the received CRC-check-sum, an I2C-CRC-error is detected, the COMM_CRC_ERR_INT bit is set, unless it is masked by the COMM_CRC_ERR_MASK bit. The MCU must clear this bit by writing a ‘1’ to the COMM_CRC_ERR_INT bit. When the CRC field is enabled, in the case when MCU attempts to write to a read-only register or a register-address that does not exist, the device sets the COMM_ADR_ERR_INT bit, unless the COMM_ADR_ERR_MASK bit is set. The MCU must clear this bit by writing a ‘1’ to the COMM_ADR_ERR_INT bit. I2C Write Cycle without CRC I2C Write Cycle with CRC The I2C controller device (the MCU) provides R_CRC[7:0], which is calculated from the I2C_ID, R/W, ADDR, and the WDATA bits (24 bits). See CRC Calculation for I2C and SPI Interface Protocols. I2C Read Cycle without CRC When READ function is to be accomplished, a WRITE function must precede the READ function as shown above. I2C READ Cycle with CRC The I2C target device (the TPS6593-Q1) provides T_CRC[7:0], which is calculated from the I2C_ID, R/W, ADDR, I2C_ID, R/W, and the RDATA bits (32 bits). See CRC Calculation for I2C and SPI Interface Protocols. Auto-Increment Feature The auto-increment feature allows writing several consecutive registers within one transmission. Every time an 8-bit word is sent to the device, the internal address index counter is incremented by one and the next register is written. #GUID-9513D4D5-9FCE-433D-8352-4E7C139123AC/SNVSA484054 lists the writing sequence to two consecutive registers. Note that auto increment feature does not support CRC protocol. Auto-Increment Example ACTION START DEVICE ADDRESS = 0x60 WRITE REGISTER ADDRESS DATA DATA STOP PMIC device ACK ACK ACK ACK Serial Peripheral Interface (SPI) The device supports SPI serial-bus interface and it operates as a peripheral device. The MCU in the system acts as the controller device. A single read and write transmission consists of 24-bit write and read cycles (32-bit if CRC is enabled) in the following order: Bits 1-8: ADDR[7:0], Register address Bits 9-11: PAGE[2:0], Page address for register Bit 12: Read/Write definition, 0 = WRITE, 1 = READ. Bits 13-16: RESERVED[4:0], Reserved, use all zeros. For Write: Bits 17-24: WDATA[7:0], write data For Write with CRC enabled: Bits 25-32: R_CRC[7:0], CRC error code calculated from bits 1-24 sent by the controller device (the MCU). See . For Read: Bits 17-24: RDATA[7:0], read data For Read with CRC enabled: Bits 25-32: T_CRC[7:0], CRC error code calculated from bits 1-16 sent by the controller device (the MCU), and bits 17-24, sent by the peripheral device (the TPS6593-Q1). See . The embedded CRC filed can be enabled or deactivated from the protocol by setting the I2C1_SPI_CRC_EN register bit to '1' - enabled, '0' - deactivated. The default of this bit is configurable through the NVM. The SDO output is in a high-impedance state when the CS pin is high. When the CS pin is low, the SDO output is always driven low except when the RDATA or SCRC bits are sent. When the RDATA or SCRC bits are sent, the SDO output is driven accordingly. The address, page, data, and CRC are transmitted MSB first. The chip-select signal (CS) must be low during the cycle transmission. The CS signal resets the interface when it is high, and must be taken high between successive cycles. Data is clocked in on the rising edge of the SCLK clock signal and it is clocked out on the falling edge of SCLK clock signal. The SPI Timing diagram shows the timing information for these signals. SPI Write Cycle SPI Write Cycle with CRC SPI Read Cycle SPI Read Cycle with CRC Due to a digital control erratum in the device, the TPS6593-Q1 pulls the nINT pin low and sets interrupt bit COMM_FRM_ERR_INT if the pin CS_SPI is low during device power-up and goes high after completion of the device power-up sequence. After system start-up, the MCU must clear this COMM_FRM_ERR_INT bit such that the TPS6593-Q1 can release the nINT pin.

The default 7-bit device address for the I2C2 interface, for accessing the watchdog configuration registers and for operating the watchdog in Q&A mode, is described in the user's guide of the orderable part number of the TPS6593-Q1 PMIC. The I2C-compatible synchronous serial interface provides access to the configurable functions and registers on the device. This protocol uses a two-wire interface for bidirectional communications between the devices connected to the bus. The two interface lines are the serial data line (SDA), and the serial clock line (SCL). Every device on the bus is assigned a unique address and acts as either a controller or a target depending on whether it generates or receives the serial clock SCL. The SCL and SDA lines must each have a pullup resistor placed somewhere on the line and remain HIGH even when the bus is idle. The device supports standard mode (100 kHz), fast mode (400 kHz), and fast mode plus (1 MHz) when VIO is 3.3 V or 1.8 V, and high-speed mode (3.4 MHz) only when VIO is 1.8 V. Data Validity The data on the SDA line must be stable during the HIGH period of the clock signal (SCL). In other words, the state of the data line can only be changed when clock signal is LOW. Data Validity Diagram Start and Stop Conditions The device is controlled through an I2C-compatible interface. START and STOP conditions classify the beginning and end of the I2C session. A START condition is defined as the SDA signal going from HIGH to LOW while the SCL signal is HIGH. A STOP condition is defined as the SDA signal going from LOW to HIGH while the SCL signal is HIGH. The I2C controller device always generates the START and STOP conditions. Start and Stop Sequences The I2C bus is considered busy after a START condition and free after a STOP condition. The I2C controller device can generate repeated START conditions during data transmission. A START and a repeated START condition are equivalent function-wise. shows the SDA and SCL signal timing for the I2C-compatible bus. For timing values, see the Specification section. I2C-Compatible Timing Transferring Data Every byte put on the SDA line must be eight bits long, with the most significant bit (MSB) being transferred first. Each byte of data has to be followed by an acknowledge bit. The acknowledge related clock pulse is generated by the controller device. The controller device releases the SDA line (HIGH) during the acknowledge clock pulse. The device pulls down the SDA line during the 9th clock pulse, signifying an acknowledge. The device generates an acknowledge after each byte has been received. There is one exception to the acknowledge after every byte rule. When the controller device is the receiver, it must indicate to the transmitter an end of data by not-acknowledging (negative acknowledge) the last byte clocked out of the target device. This negative acknowledge still includes the acknowledge clock pulse (generated by the controller device), but the SDA line is not pulled down. After the START condition, the bus controller device sends a chip address. This address is seven bits long followed by an eighth bit which is a data direction bit (READ or WRITE). For the eighth bit, a 0 indicates a WRITE and a 1 indicates a READ. The second byte selects the register to which the data is written. The third byte contains data to write to the selected register. shows an example bit format of device address 110000-Bin = 60Hex. Example Device Address For safety applications, the device supports read and write protocols with embedded CRC data fields. In a write cycle, the I2C controller device (the MCU) must provide the 8-bit CRC value after sending the write data bits and receiving the ACK from the target (the TPS6593-Q1 PMIC). The CRC value must be calculated from every bit included in the write protocol except the ACK bits from the target. See CRC Calculation for I2C and SPI Interface Protocols.

The embedded CRC field can be enabled or deactivated from the protocol by setting the I2C1_SPI_CRC_EN register bit to '1' - enabled, '0' - deactivated.

In case the calculated CRC-value does not match the received CRC-check-sum, an I2C-CRC-error is detected, the COMM_CRC_ERR_INT bit is set, unless it is masked by the COMM_CRC_ERR_MASK bit.

The device supports standard mode (100 kHz), fast mode (400 kHz), and fast mode plus (1 MHz) when VIO is 3.3 V or 1.8 V, and high-speed mode (3.4 MHz) only when VIO is 1.8 V.2 Data Validity The data on the SDA line must be stable during the HIGH period of the clock signal (SCL). In other words, the state of the data line can only be changed when clock signal is LOW.

Data Validity Diagram Data Validity Diagram Start and Stop Conditions The device is controlled through an I2C-compatible interface. START and STOP conditions classify the beginning and end of the I2C session. A START condition is defined as the SDA signal going from HIGH to LOW while the SCL signal is HIGH. A STOP condition is defined as the SDA signal going from LOW to HIGH while the SCL signal is HIGH. The I2C controller device always generates the START and STOP conditions. Start and Stop Sequences The I2C bus is considered busy after a START condition and free after a STOP condition. The I2C controller device can generate repeated START conditions during data transmission.

Each byte of data has to be followed by an acknowledge bit. The acknowledge related clock pulse is generated by the controller device. The controller device releases the SDA line (HIGH) during the acknowledge clock pulse. The device pulls down the SDA line during the 9th clock pulse, signifying an acknowledge. The device generates an acknowledge after each byte has been received. There is one exception to the acknowledge after every byte rule. When the controller device is the receiver, it must indicate to the transmitter an end of data by not-acknowledging (negative acknowledge) the last byte clocked out of the target device. This negative acknowledge still includes the acknowledge clock pulse (generated by the controller device), but the SDA line is not pulled down. After the START condition, the bus controller device sends a chip address. This address is seven bits long followed by an eighth bit which is a data direction bit (READ or WRITE). For the eighth bit, a 0 indicates a WRITE and a 1 indicates a READ. The second byte selects the register to which the data is written. The third byte contains data to write to the selected register. shows an example bit format of device address 110000-Bin = 60Hex. Example Device Address For safety applications, the device supports read and write protocols with embedded CRC data fields. In a write cycle, the I2C controller device (the MCU) must provide the 8-bit CRC value after sending the write data bits and receiving the ACK from the target (the TPS6593-Q1 PMIC). The CRC value must be calculated from every bit included in the write protocol except the ACK bits from the target. See CRC Calculation for I2C and SPI Interface Protocols. In a read cycle, the I2C target must provide the 8-bit CRC value after sending the read data bits and the ACK bit, and expect to receive the NACK from the controller at the end of the protocol. The CRC value must be calculated from every bit included in the read protocol except the ACK and NACK bits. See CRC Calculation for I2C and SPI Interface Protocols.If I2C CRC is enabled in the device and an I2C write without R_CRC bits is done, the device does not process the write request. The device does not set any interrupt bit and does not pull the nINT pin low. The embedded CRC field can be enabled or deactivated from the protocol by setting the I2C1_SPI_CRC_EN register bit to '1' - enabled, '0' - deactivated. The default of this bit is configurable through the NVM. In case the calculated CRC-value does not match the received CRC-check-sum, an I2C-CRC-error is detected, the COMM_CRC_ERR_INT bit is set, unless it is masked by the COMM_CRC_ERR_MASK bit. The MCU must clear this bit by writing a ‘1’ to the COMM_CRC_ERR_INT bit. When the CRC field is enabled, in the case when MCU attempts to write to a read-only register or a register-address that does not exist, the device sets the COMM_ADR_ERR_INT bit, unless the COMM_ADR_ERR_MASK bit is set. The MCU must clear this bit by writing a ‘1’ to the COMM_ADR_ERR_INT bit.

SPI Write Cycle SPI Write Cycle with CRC SPI Read Cycle SPI Read Cycle with CRC Due to a digital control erratum in the device, the TPS6593-Q1 pulls the nINT pin low and sets interrupt bit COMM_FRM_ERR_INT if the pin CS_SPI is low during device power-up and goes high after completion of the device power-up sequence.

Added note which explains how each register map page is addressed when using SPI.yes The registers in the TPS6593-Q1 device are organized into five internal pages. Each page represents a different type of register. The below list shows the pages with their register types: Page 0: User Registers Page 1: NVM Control, Configuration, and Test Registers Page 2: Trim Registers Page 3: SRAM for PFSM Registers Page 4: Watchdog Registers When I2C Interfaces are used, each of the above listed register pages has its own 6-bit I2C device address. In order to address Page 0 to 3, the two LSBs if the pre-configured I2C1_ID are replaced with 00 for Page 0, 01 for Page 1, 10 for Page 2 and 11 for Page 3. As an example, if I2C1_ID=0x26 (0100110b) , Page 0 to 3 have following addresses: Page 0: 0100100 Page 1: 0100101 Page 2: 0100110 Page 3: 0100111 For Page 4 the I2C device address is according register bits I2C2_ID. Therefore, in case both I2C1 and I2C2 Interfaces are used, each TPS6593-Q1 device occupies four I2C device addresses (for Page 0, Page 1, Page 2 and Page 3) on the I2C1 bus and one I2C device address (for Page 4) on the I2C2 bus. And in case only I2C1 Interfaces is used, each TPS6593-Q1 device occupies five I2C device addresses (for Page 0, Page 1, Page 2, Page 3 and Page 4) on the I2C1 bus. In case multiple devices are used on a common I2C bus, care must be taken to avoid overlapping I2C device addresses. When SPI Interface is used, the above listed register pages are addresses with the PAGE[2:0] bits: 0x0 addresses Page 0, 0x1 addresses Page 1, 0x2 addresses Page 2, 0x3 addresses Page 3 CRC Protection for Configuration, Control, and Test Registers The TPS6593-Q1 device includes a CRC-16 engine to protect all the static registers of the device. Static registers are registers in Page 1, 2, and 3, with values that do not change once loaded from NVM. The CRC-16 engine continuously checks the control registers and the SRAM in the TPS6593-Q1. The expected CRC-16 value is stored in the NVM. When the CRC-16 engine detects a mismatch between the calculated and expected CRC-16 values, the interrupt bit REG_CRC_ERR_INT is set and the device forces an orderly shutdown sequence to return to the SAFE RECOVERY state. The device NVM control, configuration, and test registers in page 1 are protected against read or write access when the device is in normal functional mode. . The CRC-16 engine uses a standard CRC-16 polynomial to calculate the internal known-good checksum-value, which is X16 + X14 + X13 + X12 + X10 + X8 + X6 + X4 + X3 + X + 1. The initial value for the remainder of the polynomial is all 1s and is in big-endian bit-stream order. The inversion of the calculated result is enabled. The CRC-16 engine assumes a default value of '0' for all undefined or reserved bits in all control registers. Therefore, the software MUST NOT write the value of '1' to any of these undefined or reserved bits. If the value of '1 is written to any undefined or reserved bit of a writable register, the CRC-16 engine detects a mismatch between the calculated and expected CRC-16 values, and hence the interrupt bit REG_CRC_ERR_INT is set and the device forces an orderly shutdown sequence to return to the SAFE RECOVERY state. CRC Protection for User Registers A 20220110 Added note about writing to RESERVED bits causing a Register Map CRC erroryes At device power-up, after the NVM data is loaded into the register map, the TPS6593-Q1 performs an initial CRC check on the User Registers. These User Registers are located in page 0 and page 4 of the register map. For this initial CRC check on the User Registers, the TPS6593-Q1 uses the same CRC-16 engine and polynomial as described in , and compares the calculated CRC-16 values against the reference CRC-16 values read from the NVM. After power-up, the content of these User Registers can change due to a write-access through an I2C or SPI interface, or by the PFSM during a state transition. To protect the content of these User Registers during operation, the TPS6593-Q1 uses a dynamic CRC-8 engine for each 128-bit segment. When a write-access occurs to the User Registers, the dynamic CRC-8 engine calculates the checksum value of the current data in the accessed segment before the update to confirm that the data in the access segment before the update is still correct. In parallel, the CRC-8 engine calculates a new checksum value of the data from the same segment, with the new data inserted at the intended register address. If the checksum on the current data before the update is correct, the new calculated checksum value is used for the next CRC cycles. During operation, the checksum value are continuously computed and verified in a round-robin fashion. The CRC-8 engine utilizes the Polynomial(0xA6) = X8 + X6 + X3 + X2 + 1, which provides a H4 hamming distance. If a RESERVED bit in a R/W configuration register gets set to 1h through a I2C/SPI write, the TPS6593-Q1 detects a CRC error in the register map. Therefore, it is important that system software involved in the I2C/SPI write-access to the TPS6593-Q1 keeps all RESERVED bits (all bits with the word RESERVED in the Register Field Description tables in the Register Map section at 0h. Register Write Protection For safety application, in order to prevent unintentional writes to the control registers, the TPS6593-Q1 device implements locking and unlocking mechanisms to many of its configuration/control registers described in the following subsections. Watchdog and ESM Configuration Registers The configuration registers for the watchdog and the ESM are locked when their monitoring functions are in operation. The locking mechanism and the list of the locked watchdog register is described under . The locking mechanism and the list of the locked ESM registers is described under Error Signal Monitor (ESM) User Registers User registers in page 0, except the ESM and the WDOG configuration registers described in , and the interrupt registers (x_INT) at address 0x5a through 0x6c in page 0, can be write protected by a dedicated lock. User must write '0x9B' to the REGISTER_LOCK register to unlock the register. Writing any value other than '0x9B' activates the lock again. To check the register lock status, user must read the REGISTER_LOCK_STATUS bit. When this bit is '0', it indicates the user registers are unlocked. When this bit is '1', the user registers are locked. During start-up sequence such as powering up for the first time, waking up from LP_STANDBY, or recovering from SAFE_RECOVERY, the user registers are unlocked automatically.

CRC Protection for User Registers A 20220110 Added note about writing to RESERVED bits causing a Register Map CRC erroryes At device power-up, after the NVM data is loaded into the register map, the TPS6593-Q1 performs an initial CRC check on the User Registers. These User Registers are located in page 0 and page 4 of the register map. For this initial CRC check on the User Registers, the TPS6593-Q1 uses the same CRC-16 engine and polynomial as described in , and compares the calculated CRC-16 values against the reference CRC-16 values read from the NVM. After power-up, the content of these User Registers can change due to a write-access through an I2C or SPI interface, or by the PFSM during a state transition. To protect the content of these User Registers during operation, the TPS6593-Q1 uses a dynamic CRC-8 engine for each 128-bit segment. When a write-access occurs to the User Registers, the dynamic CRC-8 engine calculates the checksum value of the current data in the accessed segment before the update to confirm that the data in the access segment before the update is still correct. In parallel, the CRC-8 engine calculates a new checksum value of the data from the same segment, with the new data inserted at the intended register address. If the checksum on the current data before the update is correct, the new calculated checksum value is used for the next CRC cycles. During operation, the checksum value are continuously computed and verified in a round-robin fashion. The CRC-8 engine utilizes the Polynomial(0xA6) = X8 + X6 + X3 + X2 + 1, which provides a H4 hamming distance. If a RESERVED bit in a R/W configuration register gets set to 1h through a I2C/SPI write, the TPS6593-Q1 detects a CRC error in the register map. Therefore, it is important that system software involved in the I2C/SPI write-access to the TPS6593-Q1 keeps all RESERVED bits (all bits with the word RESERVED in the Register Field Description tables in the Register Map section at 0h.

These User Registers are located in page 0 and page 4 of the register map. For this initial CRC check on the User Registers, the TPS6593-Q1 uses the same CRC-16 engine and polynomial as described in , and compares the calculated CRC-16 values against the reference CRC-16 values read from the NVM. After power-up, the content of these User Registers can change due to a write-access through an I2C or SPI interface, or by the PFSM during a state transition. To protect the content of these User Registers during operation, the TPS6593-Q1 uses a dynamic CRC-8 engine for each 128-bit segment. When a write-access occurs to the User Registers, the dynamic CRC-8 engine calculates the checksum value of the current data in the accessed segment before the update to confirm that the data in the access segment before the update is still correct. In parallel, the CRC-8 engine calculates a new checksum value of the data from the same segment, with the new data inserted at the intended register address. If the checksum on the current data before the update is correct, the new calculated checksum value is used for the next CRC cycles.

Each update of the shadowed registers needs to be done by re-asserting GET_TIME bit to 1 (i.e.: reset it to 0 and then rewrite it to 1) Note: Shadowed registers, linked to the GET_TIME feature, are a parallel set of calendar static registers, at the same I2C addresses as the dynamic registers. Note: The GET_TIME feature loads the RTC counter in the shadow registers and make the content of the shadow registers available and stable for reading. Note: The GET_TIME bit has to be set to 0 and again to 1 to get a new timing value. Note: If the time reading is done without GET_TIME, the read value comes directly from the RTC counter and software has to manage the counter change during the reading.

Each update of the shadowed registers needs to be done by re-asserting GET_TIME bit to 1 (i.e.: reset it to 0 and then rewrite it to 1) Note: Shadowed registers, linked to the GET_TIME feature, are a parallel set of calendar static registers, at the same I2C addresses as the dynamic registers. Note: The GET_TIME feature loads the RTC counter in the shadow registers and make the content of the shadow registers available and stable for reading. Note: The GET_TIME bit has to be set to 0 and again to 1 to get a new timing value. Note: If the time reading is done without GET_TIME, the read value comes directly from the RTC counter and software has to manage the counter change during the reading.

Each update of the shadowed registers needs to be done by re-asserting GET_TIME bit to 1 (i.e.: reset it to 0 and then rewrite it to 1) Note: Shadowed registers, linked to the GET_TIME feature, are a parallel set of calendar static registers, at the same I2C addresses as the dynamic registers. Note: The GET_TIME feature loads the RTC counter in the shadow registers and make the content of the shadow registers available and stable for reading. Note: The GET_TIME bit has to be set to 0 and again to 1 to get a new timing value. Note: If the time reading is done without GET_TIME, the read value comes directly from the RTC counter and software has to manage the counter change during the reading.

Application and Implementation 以下のアプリケーション情報は、TI の製品仕様に含まれるものではなく、TI ではその正確性または完全性を保証いたしません。個々の目的に対する製品の適合性については、お客様の責任で判断していただくことになります。お客様は自身の設計実装を検証しテストすることで、システムの機能を確認する必要があります。 Application Information The following sections provides more detail on the proper utilization of the PMIC. Each orderable part number has unique default non-volatile memory settings and the relevant user's guide for that orderable are available in the TPS6593-Q1 product folder . Reference these user's guides for specific application information. More generic topics and some examples are outlined here. To help with new designs, a variety of tools and documents are available in the product folder. Some examples are: Evaluation module and user guide which allow testing of various orderable part numbers, including multi-PMIC operation GUI to communicate with the PMIC Schematic and layout checklist Typical Application The PMIC is generally used to power a processor. The number of regulators needed, the required sequencing, the load current requirements, and the voltage characteristics are all critical in determining the number of PMICs used in the system as well as the external components used with it. The following section provides a generic case. For specific cases, refer to the relevant user's guide based on the orderable part number. Powering a Processor In this example, a single PMIC is used to power a generic processor. For this case, the PMIC is used in 2+1+1+1 buck phase configuration where BUCK1 and BUCK2 are used in parallel to supply higher currents. Example Power Map Design Requirements The design requirements for the sample processor in are outlined below: VDD CORE rail requires 0.8 V, 5 A MCU rail requires 0.85 V, 2 A CPU (AVS) rail requires 0.8 V, 3 A and the ability to support Adaptive Voltage Scaling LPDDR4 is used, which requires 1.1 V, 1 A and 1.8 V, 200 mA 1.8V PHYs and 0.8V PLLs and DLLs which are noise sensitive VDDA supplies the most noise sensitive components of the processor, requires 100 mA, and requires extra low noise Detailed Design Procedure Based on the above requirements, the PMIC has been configured with the connections outlined in . BUCK1 and BUCK2 are used in multiphase operation to support the 5 A current. LDO2 and LDO3 are used to power 1.8 V PHYs and 0.8 V PLLs and DLLs because they are lower noise than a buck regulator and it isolates them from the noise of VDD CORE and the LPDDR4 1.8 V supply. LDO4 is used to power VDDA because it has better noise performance. Using this configuration information, components can be chosen to use with the PMIC. VCCA The VCCA pin provides power to the LDOVINT regulator and other internal functions. This VCCA pin is always connected in parallel with the buck input pins (PVIN_Bx pins). The VCCA pin can be connected to an optional 0.47-µF bypass capacitor close to the pin.

The OSC32KCAP pin is bypassed with a 100-nF bypass capacitor for noise rejection. For the OSC32KIN and OSC32KOUT pins, a simplified oscillator schematic is shown in to determine what external load capacitors are needed for the crystal. Crystal Oscillator Component Selection CIN1 and CIN2 are both 12-pF for this device. CPCB1 and CPCB2 depend on the board but is generally around 1-pF. The crystal oscillator chosen must have a required load capacitance of either 6-pF, 9-pF, or 12.5-pF and the value of the XTAL_SEL bit in the RTC_CTRL_2 register must be updated based on the oscillator chosen. To achieve the required load capacitance (CL) for the oscillator, is used. This equation assumes that the crystal series capacitance is negligible. CL = (CL1 + CPCB1 + CIN1) × (CL2 + CPCB2 + CIN2) / ((CL1 + CPCB1 + CIN1) + (CL2 + CPCB2 + CIN2)) Assuming CL1 = CL2, this simplifies to CL1 = 2 × CL - CPCB - CIN. Simplifying this into the standard capacitor values typically available results in the following general capacitor recommendations. If more precise matching is desired, complete the exercise without series capacitance neglected and with exact PCB parasitic capacitance. Too much capacitance results in a lower than expected oscillator frequency, while not enough capacitance has the opposite impact.

Refer the part number specific user's guide to identify which configuration applies to each buck regulator. The actual minimal capacitance requirements to achieve a specific accuracy or ripple target varies depending on the input voltage, output voltage, and load transient characteristics; some guidance, however, is provided below. The local output capacitors must be placed as close to the inductor as possible to minimize electromagnetic emissions. Every buck output requires a local output capacitor to form the capacitive part of the LC output filter. It is recommended to place all large capacitors near the inductor. See for more information about component placement. Use ceramic local output capacitors, X7R or X7T types; do not use Y5V or F. DC bias voltage characteristics of ceramic capacitors must be considered. The output filter capacitor smooths out current flow from the inductor to the load, helps maintain a steady output voltage during transient load changes and reduces output voltage ripple. These capacitors must be selected with sufficient capacitance and sufficiently low ESR and ESL to perform these functions. Minimum effective output capacitance (including the DC voltage roll-off, tolerances, aging and temperature effects) is defined in Electrical Characteristics table for different buck configurations. The output voltage ripple is caused by the charging and discharging of the output capacitor and also due to its RESR. The RESR is frequency dependent (as well as temperature dependent); make sure the value used for selection process is at the switching frequency of the part. To achieve better ripple and transient performance, additional high pass filter caps are recommended to compensate for the parasitic impedance due to board routing and provide faster transient response to a load step. These caps are placed close to the point of load and are also the input capacitors of the load. These capacitors are referred to as POL caps later in this document. POL capacitor usage varies based on the application and generally follows the SoC or FPGA input capacitor requirements. Low ESL 3-terminal caps are recommended, as their high performance can help reduce the total number of capacitors required which simplifies board layout design and saves board area. They also help to reduce the total cost of the solution. Note that the output capacitor may be the limiting factor in the output voltage ramp and the maximum total output capacitance listed in electrical characteristics must not be exceeded. At shutdown the output capacitors are discharged to 0.15-V level using forced-PWM operation. This discharge of the output capacitors can cause an increase of the input voltage if the load current is small and the output capacitor is large. Below 0.15-V level the output capacitor is discharged by the internal discharge resistor and with large capacitor more time is required to settle VOUT down as a consequence of the increased time constant. is an example power distribution network (PDN) of local and POL caps at the output of a buck for optimal ripple and transient performance. lists the local and POL capacitors used to validate the buck transient and ripple performance specified in the parametric table for each of the seven configurations. lists the actual capacitor part numbers used for the different use case tests, neglecting capacitors below 10-µF.

This input supply must be well regulated and can withstand maximum input current and keep a stable voltage without voltage drop even at load transition condition. The resistance of the input supply rail must be low enough that the input current transient does not cause too high drop in the device supply voltage that can cause false UVLO fault triggering. If the input supply is located more than a few inches from the device, additional bulk capacitance may be required in addition to the ceramic bypass capacitors. Layout Layout Guidelines A 20220110 Updated Layout Guidelines with respect to output capacitor on VOUT_LDOVINT pinyes The high frequency and large switching currents of the TPS6593-Q1 device make the choice of layout important. Good power supply results only occur when care is given to correct design and layout. Layout affects noise pickup and generation and can cause a good design to perform with less-than-expected results. With a range of buck output currents from a few milliampere to 10 A and over, good power supply layout is much more difficult than most general PCB design. Use the following steps as a reference to ensure the buck regulators are stable and maintain correct voltage and current regulation across its intended operating voltage and current range. Place CIN as close as possible to the PVIN_Bx pin and the PGND/Thermal Pad. Route the VIN trace wide and thick to avoid IR drops. The DCR of the trace from the source to the pin must be less than 2 mΩ. The trace between the positive node of the input capacitor and the PVIN_Bx pins of the device, as well as the trace between the negative node of the input capacitor and PGND/Thermal Pad, must be kept as short as possible. The input capacitance provides a low-impedance voltage source for the switching converter. The inductance of the connection is the most important parameter of a local decoupling capacitor — parasitic inductance on these traces must be kept as small as possible for correct device operation. The parasitic inductance can be reduced by using a ground plane as close as possible to top layer by using thin dielectric layer between top layer and ground plane. The output filter, consisting of COUT and L, converts the switching signal at SW_Bx to the noiseless output voltage. This output filter must be placed as close as possible to the device keeping the switch node small, for best EMI behavior. Note that the PVIN_Bx pin is directly adjacent to the SW_Bx pin. The inductor and capacitor placement must be made as close as possible without compromising PVIN_Bx. Route the traces between the output capacitors of the device and the load direct and wide to avoid losses due to the IR drop. Input for analog blocks (VCCA and REFGND1/2) must be isolated from noisy signals. Connect VCCA directly to a quiet system voltage node and REFGND1/2 to a quiet ground point where no IR drop occurs. Place the decoupling capacitor as close as possible to the VCCA pin. If the processor load supports remote voltage sensing, connect the feedback pins FB_Bx of the device to the respective sense pins on the processor. If the processor does not support remote voltage sensing, then connect the FB_Bx pin to a representative load capacitor. With differential feedback, also connect the negative feedback pin to the negative terminal of the same load capacitor. The minimum recommended trace width is 6 mils. The sense lines are susceptible to noise. They must be kept away from noisy signals such as PGND, PVIN_Bx, and SW_Bx, as well as high bandwidth signals such as the I2C. Avoid capacitive and inductive coupling by keeping the sense lines short, direct, and close to each other. Run the lines in a quiet layer. Isolate them from noisy signals by a voltage or ground plane if possible. Running the signal as a differential pair is recommended. If series resistors are used for load current measurement, place them after connection of the voltage feedback. PGND, PVIN_Bx and SW_Bx must be routed on thick layers. They must not surround inner signal layers, which are not able to withstand interference from noisy PGND, PVIN_Bx and SW_Bx. For the LDO regulators, the feedback connection is internal. Therefore, it is important to keep the PCB resistance between LDO output and target load in the range of the acceptable voltage drop for LDOs. Similar to the buck regulators, the input capacitor at the PVIN_LDOx pins and the VCCA pin must be placed as close as possible to the PMIC. The impedance from the source of the PVIN_LDOx pins and the VCCA pin must be low and the DCR less than 2 mΩ. The output capacitor at the VOUT_LDOx, VOUT_LDOVINT and VOUT_LDOVRTC pins must be as close (0.5mm) to the PMIC as possible. The ground connection of these capacitors, especially for the capacitor at the VOUT_LDOVINT pin, must have a low impedance of less than 2 mΩ to the ground (Thermal Pad) of the TPS6593-Q1. For the ground connection of this capacitor at the VOUT_LDOVINT pin, use multiple vias (at least three) directly at the ground landing pad of the capacitor. See illustration below: Ground connection of capacitor at VOUT_LDOVINT pin Due to the overall small solution size, the thermal performance of the PCB layout is important. Many system-dependent parameters, such as thermal coupling, airflow, added heat sinks and convection surfaces, and the presence of other heat-generating components affect the power dissipation limits of a given component. Proper PCB layout, focusing on thermal performance, results in lower die temperatures. Wide and thick power traces come with the ability to sink dissipated heat. The capability to sink dissipated heat can be improved further on multi-layer PCB designs with vias to different planes. Improved heat-sinking capability results in reduced junction-to-ambient (RθJA) and junction-to-board (RθJB) thermal resistances and thereby reduces the device junction temperature, TJ. TI strongly recommends to perform a careful system-level 2D or full 3D dynamic thermal analysis at the beginning product design process, by using a thermal modeling analysis software. Overall recommendation for the PCB is to use at least 12 layers with 60 to 90 mil thickness, and with following weights for the Copper layers: 0.5oz for signal layers at least 1.5oz for top layer and other plane layers A more complete list of layout recommendations can be found in the Schematic and layout checklist. Layout Example A 20220110 Updated Layout Example figureyes Example PMIC Layout This example shows a top and bottom layout of the key power components and the crystal oscillator based on the EVM. Most of the digital routing is neglected in this image, see the EVM design files EVM design files for full details. The highest priority must be on the buck input capacitors, followed by the inductors, and the output capacitor on the VOUT_LDOVINT pin. Ensure that there are sufficient vias for high current pathways.

The number of regulators needed, the required sequencing, the load current requirements, and the voltage characteristics are all critical in determining the number of PMICs used in the system as well as the external components used with it. The following section provides a generic case. For specific cases, refer to the relevant user's guide based on the orderable part number. Powering a Processor In this example, a single PMIC is used to power a generic processor. For this case, the PMIC is used in 2+1+1+1 buck phase configuration where BUCK1 and BUCK2 are used in parallel to supply higher currents. Example Power Map Design Requirements The design requirements for the sample processor in are outlined below: VDD CORE rail requires 0.8 V, 5 A MCU rail requires 0.85 V, 2 A CPU (AVS) rail requires 0.8 V, 3 A and the ability to support Adaptive Voltage Scaling LPDDR4 is used, which requires 1.1 V, 1 A and 1.8 V, 200 mA 1.8V PHYs and 0.8V PLLs and DLLs which are noise sensitive VDDA supplies the most noise sensitive components of the processor, requires 100 mA, and requires extra low noise Detailed Design Procedure Based on the above requirements, the PMIC has been configured with the connections outlined in . BUCK1 and BUCK2 are used in multiphase operation to support the 5 A current. LDO2 and LDO3 are used to power 1.8 V PHYs and 0.8 V PLLs and DLLs because they are lower noise than a buck regulator and it isolates them from the noise of VDD CORE and the LPDDR4 1.8 V supply. LDO4 is used to power VDDA because it has better noise performance. Using this configuration information, components can be chosen to use with the PMIC. VCCA The VCCA pin provides power to the LDOVINT regulator and other internal functions. This VCCA pin is always connected in parallel with the buck input pins (PVIN_Bx pins). The VCCA pin can be connected to an optional 0.47-µF bypass capacitor close to the pin.

The OSC32KCAP pin is bypassed with a 100-nF bypass capacitor for noise rejection. For the OSC32KIN and OSC32KOUT pins, a simplified oscillator schematic is shown in to determine what external load capacitors are needed for the crystal. Crystal Oscillator Component Selection CIN1 and CIN2 are both 12-pF for this device. CPCB1 and CPCB2 depend on the board but is generally around 1-pF. The crystal oscillator chosen must have a required load capacitance of either 6-pF, 9-pF, or 12.5-pF and the value of the XTAL_SEL bit in the RTC_CTRL_2 register must be updated based on the oscillator chosen. To achieve the required load capacitance (CL) for the oscillator, is used. This equation assumes that the crystal series capacitance is negligible. CL = (CL1 + CPCB1 + CIN1) × (CL2 + CPCB2 + CIN2) / ((CL1 + CPCB1 + CIN1) + (CL2 + CPCB2 + CIN2)) Assuming CL1 = CL2, this simplifies to CL1 = 2 × CL - CPCB - CIN. Simplifying this into the standard capacitor values typically available results in the following general capacitor recommendations. If more precise matching is desired, complete the exercise without series capacitance neglected and with exact PCB parasitic capacitance. Too much capacitance results in a lower than expected oscillator frequency, while not enough capacitance has the opposite impact.

If the board size allows a larger foot print, a 22-µF, 10-V capacitor is recommended.

Refer the part number specific user's guide to identify which configuration applies to each buck regulator. The actual minimal capacitance requirements to achieve a specific accuracy or ripple target varies depending on the input voltage, output voltage, and load transient characteristics; some guidance, however, is provided below. The local output capacitors must be placed as close to the inductor as possible to minimize electromagnetic emissions. Every buck output requires a local output capacitor to form the capacitive part of the LC output filter. It is recommended to place all large capacitors near the inductor. See for more information about component placement. Use ceramic local output capacitors, X7R or X7T types; do not use Y5V or F. DC bias voltage characteristics of ceramic capacitors must be considered. The output filter capacitor smooths out current flow from the inductor to the load, helps maintain a steady output voltage during transient load changes and reduces output voltage ripple. These capacitors must be selected with sufficient capacitance and sufficiently low ESR and ESL to perform these functions. Minimum effective output capacitance (including the DC voltage roll-off, tolerances, aging and temperature effects) is defined in Electrical Characteristics table for different buck configurations. The output voltage ripple is caused by the charging and discharging of the output capacitor and also due to its RESR. The RESR is frequency dependent (as well as temperature dependent); make sure the value used for selection process is at the switching frequency of the part. To achieve better ripple and transient performance, additional high pass filter caps are recommended to compensate for the parasitic impedance due to board routing and provide faster transient response to a load step. These caps are placed close to the point of load and are also the input capacitors of the load. These capacitors are referred to as POL caps later in this document. POL capacitor usage varies based on the application and generally follows the SoC or FPGA input capacitor requirements. Low ESL 3-terminal caps are recommended, as their high performance can help reduce the total number of capacitors required which simplifies board layout design and saves board area. They also help to reduce the total cost of the solution. Note that the output capacitor may be the limiting factor in the output voltage ramp and the maximum total output capacitance listed in electrical characteristics must not be exceeded. At shutdown the output capacitors are discharged to 0.15-V level using forced-PWM operation. This discharge of the output capacitors can cause an increase of the input voltage if the load current is small and the output capacitor is large. Below 0.15-V level the output capacitor is discharged by the internal discharge resistor and with large capacitor more time is required to settle VOUT down as a consequence of the increased time constant. is an example power distribution network (PDN) of local and POL caps at the output of a buck for optimal ripple and transient performance. lists the local and POL capacitors used to validate the buck transient and ripple performance specified in the parametric table for each of the seven configurations. lists the actual capacitor part numbers used for the different use case tests, neglecting capacitors below 10-µF.

LDO Output Capacitors All LDO outputs require an output capacitor to hold up the output voltage during a load step or changes to the input voltage. Using a 2.2-µF capacitor for each LDO output is recommended. Note: this requirement excludes any capacitance seen at the load and only refers to the capacitance seen close to the device. Additional capacitance placed near the load can be supported, but the end application or system must be evaluated for stability.

The following section provides a generic case. For specific cases, refer to the relevant user's guide based on the orderable part number. Powering a Processor In this example, a single PMIC is used to power a generic processor. For this case, the PMIC is used in 2+1+1+1 buck phase configuration where BUCK1 and BUCK2 are used in parallel to supply higher currents. Example Power Map Design Requirements The design requirements for the sample processor in are outlined below: VDD CORE rail requires 0.8 V, 5 A MCU rail requires 0.85 V, 2 A CPU (AVS) rail requires 0.8 V, 3 A and the ability to support Adaptive Voltage Scaling LPDDR4 is used, which requires 1.1 V, 1 A and 1.8 V, 200 mA 1.8V PHYs and 0.8V PLLs and DLLs which are noise sensitive VDDA supplies the most noise sensitive components of the processor, requires 100 mA, and requires extra low noise Detailed Design Procedure Based on the above requirements, the PMIC has been configured with the connections outlined in . BUCK1 and BUCK2 are used in multiphase operation to support the 5 A current. LDO2 and LDO3 are used to power 1.8 V PHYs and 0.8 V PLLs and DLLs because they are lower noise than a buck regulator and it isolates them from the noise of VDD CORE and the LPDDR4 1.8 V supply. LDO4 is used to power VDDA because it has better noise performance. Using this configuration information, components can be chosen to use with the PMIC. VCCA The VCCA pin provides power to the LDOVINT regulator and other internal functions. This VCCA pin is always connected in parallel with the buck input pins (PVIN_Bx pins). The VCCA pin can be connected to an optional 0.47-µF bypass capacitor close to the pin.

The OSC32KCAP pin is bypassed with a 100-nF bypass capacitor for noise rejection. For the OSC32KIN and OSC32KOUT pins, a simplified oscillator schematic is shown in to determine what external load capacitors are needed for the crystal. Crystal Oscillator Component Selection CIN1 and CIN2 are both 12-pF for this device. CPCB1 and CPCB2 depend on the board but is generally around 1-pF. The crystal oscillator chosen must have a required load capacitance of either 6-pF, 9-pF, or 12.5-pF and the value of the XTAL_SEL bit in the RTC_CTRL_2 register must be updated based on the oscillator chosen. To achieve the required load capacitance (CL) for the oscillator, is used. This equation assumes that the crystal series capacitance is negligible. CL = (CL1 + CPCB1 + CIN1) × (CL2 + CPCB2 + CIN2) / ((CL1 + CPCB1 + CIN1) + (CL2 + CPCB2 + CIN2)) Assuming CL1 = CL2, this simplifies to CL1 = 2 × CL - CPCB - CIN. Simplifying this into the standard capacitor values typically available results in the following general capacitor recommendations. If more precise matching is desired, complete the exercise without series capacitance neglected and with exact PCB parasitic capacitance. Too much capacitance results in a lower than expected oscillator frequency, while not enough capacitance has the opposite impact.

If the board size allows a larger foot print, a 22-µF, 10-V capacitor is recommended.

Refer the part number specific user's guide to identify which configuration applies to each buck regulator. The actual minimal capacitance requirements to achieve a specific accuracy or ripple target varies depending on the input voltage, output voltage, and load transient characteristics; some guidance, however, is provided below. The local output capacitors must be placed as close to the inductor as possible to minimize electromagnetic emissions. Every buck output requires a local output capacitor to form the capacitive part of the LC output filter. It is recommended to place all large capacitors near the inductor. See for more information about component placement. Use ceramic local output capacitors, X7R or X7T types; do not use Y5V or F. DC bias voltage characteristics of ceramic capacitors must be considered. The output filter capacitor smooths out current flow from the inductor to the load, helps maintain a steady output voltage during transient load changes and reduces output voltage ripple. These capacitors must be selected with sufficient capacitance and sufficiently low ESR and ESL to perform these functions. Minimum effective output capacitance (including the DC voltage roll-off, tolerances, aging and temperature effects) is defined in Electrical Characteristics table for different buck configurations. The output voltage ripple is caused by the charging and discharging of the output capacitor and also due to its RESR. The RESR is frequency dependent (as well as temperature dependent); make sure the value used for selection process is at the switching frequency of the part. To achieve better ripple and transient performance, additional high pass filter caps are recommended to compensate for the parasitic impedance due to board routing and provide faster transient response to a load step. These caps are placed close to the point of load and are also the input capacitors of the load. These capacitors are referred to as POL caps later in this document. POL capacitor usage varies based on the application and generally follows the SoC or FPGA input capacitor requirements. Low ESL 3-terminal caps are recommended, as their high performance can help reduce the total number of capacitors required which simplifies board layout design and saves board area. They also help to reduce the total cost of the solution. Note that the output capacitor may be the limiting factor in the output voltage ramp and the maximum total output capacitance listed in electrical characteristics must not be exceeded. At shutdown the output capacitors are discharged to 0.15-V level using forced-PWM operation. This discharge of the output capacitors can cause an increase of the input voltage if the load current is small and the output capacitor is large. Below 0.15-V level the output capacitor is discharged by the internal discharge resistor and with large capacitor more time is required to settle VOUT down as a consequence of the increased time constant. is an example power distribution network (PDN) of local and POL caps at the output of a buck for optimal ripple and transient performance. lists the local and POL capacitors used to validate the buck transient and ripple performance specified in the parametric table for each of the seven configurations. lists the actual capacitor part numbers used for the different use case tests, neglecting capacitors below 10-µF.

BUCK1 and BUCK2 are used in multiphase operation to support the 5 A current. LDO2 and LDO3 are used to power 1.8 V PHYs and 0.8 V PLLs and DLLs because they are lower noise than a buck regulator and it isolates them from the noise of VDD CORE and the LPDDR4 1.8 V supply. LDO4 is used to power VDDA because it has better noise performance. Using this configuration information, components can be chosen to use with the PMIC. VCCA The VCCA pin provides power to the LDOVINT regulator and other internal functions. This VCCA pin is always connected in parallel with the buck input pins (PVIN_Bx pins).

The OSC32KCAP pin is bypassed with a 100-nF bypass capacitor for noise rejection. For the OSC32KIN and OSC32KOUT pins, a simplified oscillator schematic is shown in to determine what external load capacitors are needed for the crystal. Crystal Oscillator Component Selection CIN1 and CIN2 are both 12-pF for this device. CPCB1 and CPCB2 depend on the board but is generally around 1-pF. The crystal oscillator chosen must have a required load capacitance of either 6-pF, 9-pF, or 12.5-pF and the value of the XTAL_SEL bit in the RTC_CTRL_2 register must be updated based on the oscillator chosen. To achieve the required load capacitance (CL) for the oscillator, is used. This equation assumes that the crystal series capacitance is negligible. CL = (CL1 + CPCB1 + CIN1) × (CL2 + CPCB2 + CIN2) / ((CL1 + CPCB1 + CIN1) + (CL2 + CPCB2 + CIN2)) Assuming CL1 = CL2, this simplifies to CL1 = 2 × CL - CPCB - CIN. Simplifying this into the standard capacitor values typically available results in the following general capacitor recommendations. If more precise matching is desired, complete the exercise without series capacitance neglected and with exact PCB parasitic capacitance. Too much capacitance results in a lower than expected oscillator frequency, while not enough capacitance has the opposite impact.

If the board size allows a larger foot print, a 22-µF, 10-V capacitor is recommended.

Refer the part number specific user's guide to identify which configuration applies to each buck regulator. The actual minimal capacitance requirements to achieve a specific accuracy or ripple target varies depending on the input voltage, output voltage, and load transient characteristics; some guidance, however, is provided below. The local output capacitors must be placed as close to the inductor as possible to minimize electromagnetic emissions. Every buck output requires a local output capacitor to form the capacitive part of the LC output filter. It is recommended to place all large capacitors near the inductor. See for more information about component placement. Use ceramic local output capacitors, X7R or X7T types; do not use Y5V or F. DC bias voltage characteristics of ceramic capacitors must be considered. The output filter capacitor smooths out current flow from the inductor to the load, helps maintain a steady output voltage during transient load changes and reduces output voltage ripple. These capacitors must be selected with sufficient capacitance and sufficiently low ESR and ESL to perform these functions. Minimum effective output capacitance (including the DC voltage roll-off, tolerances, aging and temperature effects) is defined in Electrical Characteristics table for different buck configurations. The output voltage ripple is caused by the charging and discharging of the output capacitor and also due to its RESR. The RESR is frequency dependent (as well as temperature dependent); make sure the value used for selection process is at the switching frequency of the part. To achieve better ripple and transient performance, additional high pass filter caps are recommended to compensate for the parasitic impedance due to board routing and provide faster transient response to a load step. These caps are placed close to the point of load and are also the input capacitors of the load. These capacitors are referred to as POL caps later in this document. POL capacitor usage varies based on the application and generally follows the SoC or FPGA input capacitor requirements. Low ESL 3-terminal caps are recommended, as their high performance can help reduce the total number of capacitors required which simplifies board layout design and saves board area. They also help to reduce the total cost of the solution. Note that the output capacitor may be the limiting factor in the output voltage ramp and the maximum total output capacitance listed in electrical characteristics must not be exceeded. At shutdown the output capacitors are discharged to 0.15-V level using forced-PWM operation. This discharge of the output capacitors can cause an increase of the input voltage if the load current is small and the output capacitor is large. Below 0.15-V level the output capacitor is discharged by the internal discharge resistor and with large capacitor more time is required to settle VOUT down as a consequence of the increased time constant. is an example power distribution network (PDN) of local and POL caps at the output of a buck for optimal ripple and transient performance. lists the local and POL capacitors used to validate the buck transient and ripple performance specified in the parametric table for each of the seven configurations. lists the actual capacitor part numbers used for the different use case tests, neglecting capacitors below 10-µF.

The OSC32KCAP pin is bypassed with a 100-nF bypass capacitor for noise rejection. For the OSC32KIN and OSC32KOUT pins, a simplified oscillator schematic is shown in to determine what external load capacitors are needed for the crystal. Crystal Oscillator Component Selection CIN1 and CIN2 are both 12-pF for this device. CPCB1 and CPCB2 depend on the board but is generally around 1-pF. The crystal oscillator chosen must have a required load capacitance of either 6-pF, 9-pF, or 12.5-pF and the value of the XTAL_SEL bit in the RTC_CTRL_2 register must be updated based on the oscillator chosen. To achieve the required load capacitance (CL) for the oscillator, is used. This equation assumes that the crystal series capacitance is negligible. CL = (CL1 + CPCB1 + CIN1) × (CL2 + CPCB2 + CIN2) / ((CL1 + CPCB1 + CIN1) + (CL2 + CPCB2 + CIN2)) Assuming CL1 = CL2, this simplifies to CL1 = 2 × CL - CPCB - CIN. Simplifying this into the standard capacitor values typically available results in the following general capacitor recommendations. If more precise matching is desired, complete the exercise without series capacitance neglected and with exact PCB parasitic capacitance.

Refer the part number specific user's guide to identify which configuration applies to each buck regulator. The actual minimal capacitance requirements to achieve a specific accuracy or ripple target varies depending on the input voltage, output voltage, and load transient characteristics; some guidance, however, is provided below. The local output capacitors must be placed as close to the inductor as possible to minimize electromagnetic emissions. Every buck output requires a local output capacitor to form the capacitive part of the LC output filter. It is recommended to place all large capacitors near the inductor. See for more information about component placement. Use ceramic local output capacitors, X7R or X7T types; do not use Y5V or F. DC bias voltage characteristics of ceramic capacitors must be considered. The output filter capacitor smooths out current flow from the inductor to the load, helps maintain a steady output voltage during transient load changes and reduces output voltage ripple. These capacitors must be selected with sufficient capacitance and sufficiently low ESR and ESL to perform these functions. Minimum effective output capacitance (including the DC voltage roll-off, tolerances, aging and temperature effects) is defined in Electrical Characteristics table for different buck configurations. The output voltage ripple is caused by the charging and discharging of the output capacitor and also due to its RESR. The RESR is frequency dependent (as well as temperature dependent); make sure the value used for selection process is at the switching frequency of the part. To achieve better ripple and transient performance, additional high pass filter caps are recommended to compensate for the parasitic impedance due to board routing and provide faster transient response to a load step. These caps are placed close to the point of load and are also the input capacitors of the load. These capacitors are referred to as POL caps later in this document. POL capacitor usage varies based on the application and generally follows the SoC or FPGA input capacitor requirements. Low ESL 3-terminal caps are recommended, as their high performance can help reduce the total number of capacitors required which simplifies board layout design and saves board area. They also help to reduce the total cost of the solution. Note that the output capacitor may be the limiting factor in the output voltage ramp and the maximum total output capacitance listed in electrical characteristics must not be exceeded. At shutdown the output capacitors are discharged to 0.15-V level using forced-PWM operation. This discharge of the output capacitors can cause an increase of the input voltage if the load current is small and the output capacitor is large. Below 0.15-V level the output capacitor is discharged by the internal discharge resistor and with large capacitor more time is required to settle VOUT down as a consequence of the increased time constant. is an example power distribution network (PDN) of local and POL caps at the output of a buck for optimal ripple and transient performance. lists the local and POL capacitors used to validate the buck transient and ripple performance specified in the parametric table for each of the seven configurations. lists the actual capacitor part numbers used for the different use case tests, neglecting capacitors below 10-µF.

Dependent on availability; may switch to 470 µF. The buck converters have seven potential NVM configurations which can impact the output capacitor selection. Refer the part number specific user's guide to identify which configuration applies to each buck regulator. The actual minimal capacitance requirements to achieve a specific accuracy or ripple target varies depending on the input voltage, output voltage, and load transient characteristics; some guidance, however, is provided below. The local output capacitors must be placed as close to the inductor as possible to minimize electromagnetic emissions. Every buck output requires a local output capacitor to form the capacitive part of the LC output filter. It is recommended to place all large capacitors near the inductor. See for more information about component placement. Use ceramic local output capacitors, X7R or X7T types; do not use Y5V or F. DC bias voltage characteristics of ceramic capacitors must be considered. The output filter capacitor smooths out current flow from the inductor to the load, helps maintain a steady output voltage during transient load changes and reduces output voltage ripple. These capacitors must be selected with sufficient capacitance and sufficiently low ESR and ESL to perform these functions. Minimum effective output capacitance (including the DC voltage roll-off, tolerances, aging and temperature effects) is defined in Electrical Characteristics table for different buck configurations. The output voltage ripple is caused by the charging and discharging of the output capacitor and also due to its RESR. The RESR is frequency dependent (as well as temperature dependent); make sure the value used for selection process is at the switching frequency of the part. ESRESRTo achieve better ripple and transient performance, additional high pass filter caps are recommended to compensate for the parasitic impedance due to board routing and provide faster transient response to a load step. These caps are placed close to the point of load and are also the input capacitors of the load. These capacitors are referred to as POL caps later in this document. POL capacitor usage varies based on the application and generally follows the SoC or FPGA input capacitor requirements. Low ESL 3-terminal caps are recommended, as their high performance can help reduce the total number of capacitors required which simplifies board layout design and saves board area. They also help to reduce the total cost of the solution.Note that the output capacitor may be the limiting factor in the output voltage ramp and the maximum total output capacitance listed in electrical characteristics must not be exceeded. At shutdown the output capacitors are discharged to 0.15-V level using forced-PWM operation. This discharge of the output capacitors can cause an increase of the input voltage if the load current is small and the output capacitor is large. Below 0.15-V level the output capacitor is discharged by the internal discharge resistor and with large capacitor more time is required to settle VOUT down as a consequence of the increased time constant.OUT is an example power distribution network (PDN) of local and POL caps at the output of a buck for optimal ripple and transient performance. lists the local and POL capacitors used to validate the buck transient and ripple performance specified in the parametric table for each of the seven configurations. lists the actual capacitor part numbers used for the different use case tests, neglecting capacitors below 10-µF. It is recommended to simulate and validate that the capacitor network chosen for a particular design meets the desired requirements as these are provided as guidelines.

Layout Layout Guidelines A 20220110 Updated Layout Guidelines with respect to output capacitor on VOUT_LDOVINT pinyes The high frequency and large switching currents of the TPS6593-Q1 device make the choice of layout important. Good power supply results only occur when care is given to correct design and layout. Layout affects noise pickup and generation and can cause a good design to perform with less-than-expected results. With a range of buck output currents from a few milliampere to 10 A and over, good power supply layout is much more difficult than most general PCB design. Use the following steps as a reference to ensure the buck regulators are stable and maintain correct voltage and current regulation across its intended operating voltage and current range. Place CIN as close as possible to the PVIN_Bx pin and the PGND/Thermal Pad. Route the VIN trace wide and thick to avoid IR drops. The DCR of the trace from the source to the pin must be less than 2 mΩ. The trace between the positive node of the input capacitor and the PVIN_Bx pins of the device, as well as the trace between the negative node of the input capacitor and PGND/Thermal Pad, must be kept as short as possible. The input capacitance provides a low-impedance voltage source for the switching converter. The inductance of the connection is the most important parameter of a local decoupling capacitor — parasitic inductance on these traces must be kept as small as possible for correct device operation. The parasitic inductance can be reduced by using a ground plane as close as possible to top layer by using thin dielectric layer between top layer and ground plane. The output filter, consisting of COUT and L, converts the switching signal at SW_Bx to the noiseless output voltage. This output filter must be placed as close as possible to the device keeping the switch node small, for best EMI behavior. Note that the PVIN_Bx pin is directly adjacent to the SW_Bx pin. The inductor and capacitor placement must be made as close as possible without compromising PVIN_Bx. Route the traces between the output capacitors of the device and the load direct and wide to avoid losses due to the IR drop. Input for analog blocks (VCCA and REFGND1/2) must be isolated from noisy signals. Connect VCCA directly to a quiet system voltage node and REFGND1/2 to a quiet ground point where no IR drop occurs. Place the decoupling capacitor as close as possible to the VCCA pin. If the processor load supports remote voltage sensing, connect the feedback pins FB_Bx of the device to the respective sense pins on the processor. If the processor does not support remote voltage sensing, then connect the FB_Bx pin to a representative load capacitor. With differential feedback, also connect the negative feedback pin to the negative terminal of the same load capacitor. The minimum recommended trace width is 6 mils. The sense lines are susceptible to noise. They must be kept away from noisy signals such as PGND, PVIN_Bx, and SW_Bx, as well as high bandwidth signals such as the I2C. Avoid capacitive and inductive coupling by keeping the sense lines short, direct, and close to each other. Run the lines in a quiet layer. Isolate them from noisy signals by a voltage or ground plane if possible. Running the signal as a differential pair is recommended. If series resistors are used for load current measurement, place them after connection of the voltage feedback. PGND, PVIN_Bx and SW_Bx must be routed on thick layers. They must not surround inner signal layers, which are not able to withstand interference from noisy PGND, PVIN_Bx and SW_Bx. For the LDO regulators, the feedback connection is internal. Therefore, it is important to keep the PCB resistance between LDO output and target load in the range of the acceptable voltage drop for LDOs. Similar to the buck regulators, the input capacitor at the PVIN_LDOx pins and the VCCA pin must be placed as close as possible to the PMIC. The impedance from the source of the PVIN_LDOx pins and the VCCA pin must be low and the DCR less than 2 mΩ. The output capacitor at the VOUT_LDOx, VOUT_LDOVINT and VOUT_LDOVRTC pins must be as close (0.5mm) to the PMIC as possible. The ground connection of these capacitors, especially for the capacitor at the VOUT_LDOVINT pin, must have a low impedance of less than 2 mΩ to the ground (Thermal Pad) of the TPS6593-Q1. For the ground connection of this capacitor at the VOUT_LDOVINT pin, use multiple vias (at least three) directly at the ground landing pad of the capacitor. See illustration below: Ground connection of capacitor at VOUT_LDOVINT pin Due to the overall small solution size, the thermal performance of the PCB layout is important. Many system-dependent parameters, such as thermal coupling, airflow, added heat sinks and convection surfaces, and the presence of other heat-generating components affect the power dissipation limits of a given component. Proper PCB layout, focusing on thermal performance, results in lower die temperatures. Wide and thick power traces come with the ability to sink dissipated heat. The capability to sink dissipated heat can be improved further on multi-layer PCB designs with vias to different planes. Improved heat-sinking capability results in reduced junction-to-ambient (RθJA) and junction-to-board (RθJB) thermal resistances and thereby reduces the device junction temperature, TJ. TI strongly recommends to perform a careful system-level 2D or full 3D dynamic thermal analysis at the beginning product design process, by using a thermal modeling analysis software. Overall recommendation for the PCB is to use at least 12 layers with 60 to 90 mil thickness, and with following weights for the Copper layers: 0.5oz for signal layers at least 1.5oz for top layer and other plane layers A more complete list of layout recommendations can be found in the Schematic and layout checklist. Layout Example A 20220110 Updated Layout Example figureyes Example PMIC Layout This example shows a top and bottom layout of the key power components and the crystal oscillator based on the EVM. Most of the digital routing is neglected in this image, see the EVM design files EVM design files for full details. The highest priority must be on the buck input capacitors, followed by the inductors, and the output capacitor on the VOUT_LDOVINT pin. Ensure that there are sufficient vias for high current pathways. Layout Layout Guidelines A 20220110 Updated Layout Guidelines with respect to output capacitor on VOUT_LDOVINT pinyes The high frequency and large switching currents of the TPS6593-Q1 device make the choice of layout important. Good power supply results only occur when care is given to correct design and layout. Layout affects noise pickup and generation and can cause a good design to perform with less-than-expected results. With a range of buck output currents from a few milliampere to 10 A and over, good power supply layout is much more difficult than most general PCB design. Use the following steps as a reference to ensure the buck regulators are stable and maintain correct voltage and current regulation across its intended operating voltage and current range. Place CIN as close as possible to the PVIN_Bx pin and the PGND/Thermal Pad. Route the VIN trace wide and thick to avoid IR drops. The DCR of the trace from the source to the pin must be less than 2 mΩ. The trace between the positive node of the input capacitor and the PVIN_Bx pins of the device, as well as the trace between the negative node of the input capacitor and PGND/Thermal Pad, must be kept as short as possible. The input capacitance provides a low-impedance voltage source for the switching converter. The inductance of the connection is the most important parameter of a local decoupling capacitor — parasitic inductance on these traces must be kept as small as possible for correct device operation. The parasitic inductance can be reduced by using a ground plane as close as possible to top layer by using thin dielectric layer between top layer and ground plane. The output filter, consisting of COUT and L, converts the switching signal at SW_Bx to the noiseless output voltage. This output filter must be placed as close as possible to the device keeping the switch node small, for best EMI behavior. Note that the PVIN_Bx pin is directly adjacent to the SW_Bx pin. The inductor and capacitor placement must be made as close as possible without compromising PVIN_Bx. Route the traces between the output capacitors of the device and the load direct and wide to avoid losses due to the IR drop. Input for analog blocks (VCCA and REFGND1/2) must be isolated from noisy signals. Connect VCCA directly to a quiet system voltage node and REFGND1/2 to a quiet ground point where no IR drop occurs. Place the decoupling capacitor as close as possible to the VCCA pin. If the processor load supports remote voltage sensing, connect the feedback pins FB_Bx of the device to the respective sense pins on the processor. If the processor does not support remote voltage sensing, then connect the FB_Bx pin to a representative load capacitor. With differential feedback, also connect the negative feedback pin to the negative terminal of the same load capacitor. The minimum recommended trace width is 6 mils. The sense lines are susceptible to noise. They must be kept away from noisy signals such as PGND, PVIN_Bx, and SW_Bx, as well as high bandwidth signals such as the I2C. Avoid capacitive and inductive coupling by keeping the sense lines short, direct, and close to each other. Run the lines in a quiet layer. Isolate them from noisy signals by a voltage or ground plane if possible. Running the signal as a differential pair is recommended. If series resistors are used for load current measurement, place them after connection of the voltage feedback. PGND, PVIN_Bx and SW_Bx must be routed on thick layers. They must not surround inner signal layers, which are not able to withstand interference from noisy PGND, PVIN_Bx and SW_Bx. For the LDO regulators, the feedback connection is internal. Therefore, it is important to keep the PCB resistance between LDO output and target load in the range of the acceptable voltage drop for LDOs. Similar to the buck regulators, the input capacitor at the PVIN_LDOx pins and the VCCA pin must be placed as close as possible to the PMIC. The impedance from the source of the PVIN_LDOx pins and the VCCA pin must be low and the DCR less than 2 mΩ. The output capacitor at the VOUT_LDOx, VOUT_LDOVINT and VOUT_LDOVRTC pins must be as close (0.5mm) to the PMIC as possible. The ground connection of these capacitors, especially for the capacitor at the VOUT_LDOVINT pin, must have a low impedance of less than 2 mΩ to the ground (Thermal Pad) of the TPS6593-Q1. For the ground connection of this capacitor at the VOUT_LDOVINT pin, use multiple vias (at least three) directly at the ground landing pad of the capacitor. See illustration below: Ground connection of capacitor at VOUT_LDOVINT pin Due to the overall small solution size, the thermal performance of the PCB layout is important. Many system-dependent parameters, such as thermal coupling, airflow, added heat sinks and convection surfaces, and the presence of other heat-generating components affect the power dissipation limits of a given component. Proper PCB layout, focusing on thermal performance, results in lower die temperatures. Wide and thick power traces come with the ability to sink dissipated heat. The capability to sink dissipated heat can be improved further on multi-layer PCB designs with vias to different planes. Improved heat-sinking capability results in reduced junction-to-ambient (RθJA) and junction-to-board (RθJB) thermal resistances and thereby reduces the device junction temperature, TJ. TI strongly recommends to perform a careful system-level 2D or full 3D dynamic thermal analysis at the beginning product design process, by using a thermal modeling analysis software. Overall recommendation for the PCB is to use at least 12 layers with 60 to 90 mil thickness, and with following weights for the Copper layers: 0.5oz for signal layers at least 1.5oz for top layer and other plane layers A more complete list of layout recommendations can be found in the Schematic and layout checklist.
