7.3.5.4 DESAT based Short Circuit Protection (DESAT)

DESAT protection prevents the power transistor from damage in case of short circuit faults. The DESAT input monitors the VCEsat (IGBT)/VDSon (MOSFET) through an external resistor and diode network (R1, C1, D1 and D2 in Figure 7-16). The D1 diode protects the driver IC from high voltage when the power transistor is OFF. The resistor, R1, limits the negative voltage applied on the DESAT input during switching transitions. While the power FET is ON, an internal current source, ICHG, forward biases the DESAT diode and dumps into the collector/drain of the external power switch. Under normal conditions, the VCEsat/VDSon is less than a few volts, however, during short circuit faults the VCEsat/VDSon may rise up to the DC bus voltage when the power transistor operates in the linear region. In this situation, the D1 diode is reverse biased, so the internal current source charges the blanking capacitor (C1) Once the voltage on the DESAT input charges up to the selected threshold (VDESATth),the driver output is pulled into the safe state defined by the CFG10[FS_STATE_DESAT_SCP] bit (CFG10), the fault is indicated in the STATUS3[DESAT_FAULT] (STATUS3), and, if unmasked, the NFLT1 output pulls low. The turn-off of the driver output during a DESAT fault is selectable between normal, soft turn-off (STO), or two-level turnoff (2LTO) dictated by the CFG5[2LTOFF_STO_EN] bits (CFG5). See the Section 7.3.5.9and Section 7.3.5.8 for additional details on STO and 2LTO, respectively. The blanking capacitor is fully discharged at the falling edge of the PWM signal using the internal discharge current (IDCHG). In addition to the blanking time, DESAT is deglitched to prevent false triggering during transitions. The deglitch is selectable using the CFG4[DESAT_DEGLITCH] bit (CFG4).

The DESAT threshold is selectable using the CFG5[DESATTH] bits (CFG5), and the DESAT charging current (ICHG) is selectable, using the CFG5[DESAT_CHG_CURR] bits (CFG5), to control the blanking time (tDS_BLK). The discharge current is enabled/disabled using the CFG5[DESAT_DCHG_EN] bit (CFG5). The DESAT protection function is enabled or disabled using the CFG4[DESAT_EN] bit (CFG4). The implementation diagram and timing schemes of DESAT based short circuit protection are presented in Figure 7-16 and Figure 7-17 respectively.

device, targeted for EV/HEV traction inverter applications. The flexibility of SPI programming of blanking times, deglitches, thresholds, function enables, and fault handling allow the UCC5870-Q1 to support a wide variety of IGBT or SiC power transistors that are used across all EV/HEV traction inverter applications. UCC5870-Q1 integrates all of the protection features required in most traction inverter applications. Additionally, the 30A gate drive capability eliminates the need for external booster circuit, reducing overall solution size. The integrated Miller clamp circuit holds the gate off during transient events and can be configured to use the internal 4A pulldown, or drive an external n-channel MOSFET. Advanced, internal capacitor-based isolation technology maximizes CMTI performance, while minimizing the radiated emissions. All of the protections for the power transistor are integrated into the UCC5870-Q1. It supports DESAT and resistor based overcurrent protection. A negative temperature coefficient power transistor temperature sensor monitor is built into the device to alert the host and prevent damage from over-temperature conditions in the switch. A zener-breakdown based clamping function is integrated to reduce the gate drive, and thereby the overshoot energy, when over voltage spikes occur during turn-off caused by inductive kick-back. Real time gate monitoring is integrated to ensure proper connection to the power transistor and alert the host to a fault in the gate driver path. A 10-bit ADC is built-in to the UCC5870-Q1 to provide information on power switch temperature, gate driver temperature, or any voltage that must be monitored on the secondary (high-voltage) side of the gate driver. There are six inputs (AIx) available to measure voltages with the ADC. This is convenient for acquire information on the DC-LINK voltage, or for measuring the VCE/VDS voltage of the power transistor during operation. The ADC features "center mode" operation to ensure low noise measurements, or can be used in a traditional "edge mode" to achieve as many measurements as possible during a PWM cycle. In addition to reading back the ADC information over SPI, a DOUT function provides a feedback signal representing one of the user-selected AIx voltages that can be monitored real-time on the primary side. The UCC5870-Q1 integrates many safety diagnostics that enable designers to more easily implement an ASIL rated system. There are diagnostics for all of the protection features, as well as latent fault detection for circuits in the gate driver IC itself. The faults are indicated using open-drain outputs, and the specific fault is easily determined using the SPI readback. In addition to all of the safety diagnostic features, the IC integrates a primary side and secondary side "active short circuit" circuits to provide the system designer with a secondary path to control a zero-vector state for the traction inverter in the case of motor controller failure. Throughout the document, "*" are used as wild cards (typically to indicate numbers such as AI* means AI1 - AI6. Additionally, SPI bits are referred to in the following convention: REGNAME[BITNAME] Functional Block Diagram Feature Description Power Supplies The device uses three external supplies for power. VCC1 supplies the low voltage primary side that interfaces with the controller. VCC2 and VEE2 provide the gate drive supplies for the power FET. In addition, there are 3 integrated supplies (VREG1, VREG2, and VREF) used to power internal circuits. VCC1 VCC1 supports an input range of 3V to 5.5V in order to support both 3.3V and 5V controller signaling. VCC1 is monitored with both an undervoltage and overvoltage comparator circuit to ensure valid operation. UV and OV conditions of VCC1 are recorded in STATUS2[UVLO1_FAULT] and STATUS2[OVLO_FAULT1], respectively(STATUS2). See the Undervoltage Lockout (UVLO) and Overvoltage Lockout (OVLO) section for more specifics regarding the OV and UV functions. VCC2 VCC2 operates within an input range of 15V and 30V, allowing for use in IGBT and SiC applications. VCC2 is monitored with both an undervoltage and overvoltage comparator circuit to ensure valid operation. UV and OV conditions of VCC2 are recorded in STATUS3[UVLO2_FAULT] and STATUS3[OVLO2_FAULT], respectively (STATUS3 ). See the Undervoltage Lockout (UVLO) and Overvoltage Lockout (OVLO) section for more specifics regarding the OV and UV functions. VEE2 VEE2 operates with an input range of -12V to 0V, allowing a negative gate bias on the power FET during turn-off in both IGBT and SiC applications. This prevents the power FET from unintentionally turning on due to current inducted from the Miller effect. For operation with a unipolar supply, connect VEE2 to GND2. VEE2 is monitored with both an undervoltage and overvoltage comparator circuit to ensure valid operation. UV and OV conditions of VEE2 are recorded in STATUS3[UVLO3_FAULT] and STATUS3[OVLO3_FAULT], respectively (STATUS3 ). See the Undervoltage Lockout (UVLO) and Overvoltage Lockout (OVLO) section for more specifics regarding the OV and UV functions. VREG1 VREG1 is internally generated from VCC1. VREG1 regulates to 1.8V, and supplies internal circuits on the primary side. VREG1 requires a 4.7µF bypass capacitance from VREG1 to GND1 for proper operation. The current out of VREG1 is limited and this current limit is monitored. If the current limit is active for the deglitch time, a internal regulation overcurrent fault is recorded in STATUS2[VREG1_ILIMIT_FAULT]. If unmasked, nFLT1 goes low. Additionally, VREG1 is monitored for both undervoltage and overvoltage conditions. Any VREG1 UV fault is recorded in STATUS2[INT_REG_PRI_FAULT] (STATUS2 ). Any OV condition on VREG1 causes the VREG1 output to latch off and shuts down the device. This action results in a secondary communication failure, which shuts down the driver output according to CFG10[FS_STATE_INT_COMM_SEC] bit (CFG10). The VCC1 and VCC2 power must be recycled in order to restart the device. VREG2 VREG2 is internally generated from VCC2. VREG2 regulates to 1.8V with respect to VEE2, and supplies internal circuits on the secondary side. VREG2 requires a 4.7µF bypass capacitance from VREG2 to VEE2 for proper operation. The current out of VREG2 is limited and this current limit is monitored. If the current limit is active for the deglitch time, a internal regulation overcurrent fault is recorded in STATUS3[VREG2_ILIMIT_FAULT] (STATUS3). If unmasked, nFLT1 goes low. Additionally, VREG2 is monitored for both undervoltage and overvoltage conditions. Any VREG2 OV/UV faults are recorded in STATUS3[INT_REG_SEC_FAULT] (STATUS3 ). Any OV condition on VREG2 causes the VREG2 output to latch off and shuts down the driver output. The VCC2 power must be recycled in order to restart the driver output. Additionally, the driver must be reconfigured to ensure correct operation. VREF VREF is the reference for the ADC. VREF requires a 4V supply for the ADC to function properly. The error of the VREF translates directly to the error at the ADC. VREF is selectable to be powered internally, or alternatively, an external precision reference may be used to enhance the accuracy of the ADC. Use the CFG8[VREF_SEL] (CFG8) bit to select between the internal and external reference. The current out of VREF is limited and this current limit is monitored. If the current limit is active for the deglitch time, a internal regulation overcurrent fault is detected. Additionally, VREF is monitored for both undervoltage and overvoltage conditions. When any VREFILIM and/or OV/UV faults occur, the faults are recorded in STATUS5[ADC_FAULT] (STATUS5). If unmasked, nFLT1 goes low. Other Internal Rails There are several internal rails that are used to power the device. All of the internal rails are monitored for OV and UV conditions. Any OV/UV faults are recorded in the STATUS2[INT_REG_PRI_FAULT] (STATUS2) and STATUS3[INT_REG_SEC_FAULT] (STATUS3) bits. Bootstrap (VBST) and charge pump circuits generate the 4.5V power supply for the high side NMOS of internal driver stage. The implementation diagram is shown in . The external cap on BST is charged to 4.5V while OUTL is on (MN2 is on). While OUTH is on (MN1 is on), the capacitor voltage is stacked above OUTH and supplies the gate drive for the high-side NMOS. Under most conditions, the bootstrap circuit is used and the timing operates as shown in . However, for slow switching frequencies at high duty cycles the external capacitor may not be able to charge enough during the OUTH off time to supply the gate drive for the entire on-time. In these conditions, the charge pump circuit is used to hold the voltage across the bootstrap capacitor. . Implementation diagram of bootstrap and charge pump circuits. Timing diagram of bootstrap circuit. Driver Stage C 20210503 Updated drive strength to 30 A to align with typical value yes The driver stage is an integrated, 30-A current buffer. The high output drive capability enables the device to directly drive power transistors with current ratings up to 1000A without an external buffer. The drive strength is selectable to 16.7%, 33%, or 100% using CFG8[IOUT_SEL] (CFG8). The output drive is split, enabling users to customize rise and fall times independently. . Integrated ADC for Front-End Analog (FEA) Signal Processing A 10bit ADC is integrated to enable the user to digitally monitor up to 6 analog input voltages (AI*). Additionally, the junction temperature of the device is available as well as an input for measuring the VTH of the power FET. The ADC has a full scale voltage range of 0 to 3.6V, requiring 4V at VREF (either internal or external). The ADC conversions are aligned with the INP signal to ensure the least amount of noise coupling from the switching transients of the power transistors (TI proprietary). Once a conversion is complete, the conversion results are transferred to the primary side of the device with inter-die communication and the result is stored in the ADCDATA* registers. The last ADC result is always available in the register. Every ADC conversion is recorded with time stamp information for that conversion. The time stamp is the INP cycle where the measurement occurs. Once the ADC and the driver are enabled, the time stamp increments with every INP low to high edge. If a fault occurs, or the duty cycle is such that a transition is not seen on INP, the TIME_STAMP does not update. VAI* = VADC (in decimal) × 3.519mV Die Temperature (C) = VADC(in decimal) * 0.7015°C - 198.36 The AI* inputs are configurable by the user to enable/disable bias currents and comparator monitoring AI1, AI3, and AI5 are specially designed to monitor the temperature diode that is integrated into the power FET module, while A2, A4, and A6 are designed to measure the power FET current, typically from an integrated sense FET in the module. However, the inputs are not required to be used in these functions, and are configurable to measure any voltage up to 3.6V regardless of the source. The implementation of ADC sensing circuits is presented in . Block diagram of implementation of ADC processing for the case where three power transistors are connected in parallel. AI* Setup AI5 and AI6 are dual purpose inputs. By default, these inputs are configured to be control inputs for the secondary side ASC function (see the ASC section for more details). If AI5 and AI6 are to be used as current sense/ temperature sense/ ADC inputs, write CFG8[AI_ASC_MUX] = 1 (CFG8) to disable the ASC functionality. All of the AI* inputs have current sources that may be enabled using the CFG3[ITO1_EN] bit (CFG3) for AI1,3,5 and the CFG3[ITO2_EN] bit (CFG3) for the AI2,4,6. Additionally, the AI1, AI3, and AI5 inputs are designed with a zero-temperature coefficient bias current (IZTC) to bias the NTC diodes integrated into the external power switch module. Use CFG3[AI_IZTC_SEL] bits (CFG3) to enable the required bias currents for the application. The AI* inputs require an RC filter for most accurate results. See the section for details on selecting the correct RC values. ADC Setup and Sampling Modes The ADC is enabled/disabled with SPI communication to CFG7[ADC[ADC_EN] (CFG7). The 6 AI inputs as well as the die junction temperature are selectable to measure with the ADC. Additionally, the channels are selectable as to when it is samples with respect to the INP switching cycle. Use the ADCCFG[ADC_ON_CH_SEL_*] bits (ADCCFG) to select the channels to be measured while INP is high. The sampling order for the PWM ON cycle round robin is: AI1, AI3, AI5, AI2, AI4, AI6, Die Temp. Use the ADCCFG[ADC_OFF_CH_SEL_*] bits () to select the channels to be measured while INP is low. Use the CFG7[ADC_SAMP_MODE] bits (ADCCFG) to select one of 3 sampling modes for the ADC. Three modes are available to ensure the least amount of switching noise in the measurement. The three modes are Center Aligned mode (CFG7[ADC_SAMP_MODE]=0b00), where each selected channel is sampled in the center of the ON/OFF time of the INP input (depending on the setting), Edge Mode (CFG7[ADC_SAMP_MODE] = 0b01), where the ADC conversions begin after rising or falling edge (depending on the setting), and Hybrid mode (CFG7[ADC_SAMP_MODE] = 0b10), which is a combination of both modes. The maximum INP frequency supported in order to get at least one full ADC conversion per PWM cycle is 30kHz. Center Sampling Mode When using Center sampling mode (CFG7[ADC_SAMP_MODE]=0b00), the center is calculated for the ON or OFF time on INP (depending on the channel selection setup) based on the previous switching cycle. One channel is sampled during each ON or OFF time depending on the channel selections. The timing for Center mode is illustrated in the following figures. ADC center sampling mode ADC center sample mode timing chart Edge Sampling Mode Edge Mode (CFG7[ADC_SAMP_MODE] = 0b01) begins the ADC conversions based on the INP edge. When INP transitions, the ADC begins conversions for the round robin after the programmable delay time (programmed using CFG7[ADC_SAMP_DLY]). The channels selected for the PWM ON time are sampled after a rising edge of INP, while the channels selected for the PWM OFF time are sampled after a falling edge. The round robin continues until the next edge of INP. The timing for Edge mode is illustrated in the following figures. ADC edge sampling mode ADC Edge sampling mode timing chart Hybrid Mode Hybrid Mode (CFG7[ADC_SAMP_MODE]=0b10) operates using a combination of the modes. Center mode is used until the INP period is greater than the hybrid period (thybrid) when edge mode is used. The timing for Hybrid mode is illustrated in the following figures. ADC Hybrid sampling mode timing chart DOUT Functionality The device also provides an analog feedback functionality for the ADC for applications that do not want to maintain continuous SPI communication. When enabled, the DOUT output provides a PWM signal with a duty cycle proportional to the signal that is selected to be monitored. Any of the AI* inputs and the TJ are available for monitoring on the DOUT output. As there is only one DOUT output, only one channel is selectable. Typically, DOUT is either directly monitored by the MCU, or run through an RC filter to convert it to an analog voltage that may be digitized and monitored by the host controller. In order to use the DOUT function, the nFLT2 pin must be reconfigured to select the DOUT functionality using the CFG1[NFLT2_DOUT_MUX] bit (CFG1 ). When the DOUT mode is selected, any warning or fault that was selected to report to nFLT2 now reports to nFLT1 automatically. Additionally, the frequency of DOUT is selectable between 4 options using the DOUTCFG[FREQ_DOUT] bits (DOUTCFG ). Select the channel to be monitored, using the DOUTCFG[DOUT_TO_AI*] bits (for the AI* inputs, DOUTCFG ) or the DOUTCFG[DOUT_TO_TJ] bit (DOUTCFG ) for the die junction temperature. If multiple channels are selected in the register, the duty cycle constantly changes as the ADC cycles through each channel read. It is recommended to only select one channel at a time for the DOUT function. In addition to this setup, the ADC must be enabled and setup correctly to read the desired channel to be monitored. See the ADC section for details on configuring the ADC. If a fault occurs that stops the driver output and ADC measurements, the DOUT output continues and represents the last good ADC reading. Fault and Warning Classification The device integrates extensive error detection and monitoring features. These features allow the design of a robust system that protects against a variety of system related failure modes. When one of the monitored warnings or faults occurs, if unmasked, the nFLT1 output (for faults) or the nFLT2 output (for warnings) pulls low. All of the fault and warning bits have corresponding configuration bits that allow the user to mask the error or fault from showing up on the nFLT* output. The naming convention is straightforward. The mask bit is in a CFG* register and is named the same as the fault with the addition of an "_P". For example, a power FET short circuit current fault is indicated in the register bit STATUS3[SC_FAULT] (STATUS3)and the mask bit is CFG9[SC_FAULT_P] (CFG9). Throughout this document, the different warning/error bit locations are indicated in the functional description of the block where the warning/fault is monitored. When masked, the nFLT* indication does not occur, but the STATUS* bits still indicate the warning/fault condition. The device classifies error events into two categories, Warnings and Faults, and takes different device actions depending on the error classification. The Warning error class is used to report non-critical fault conditions. Warning errors are only reported with no action taken to affect the gate driver output or any other block. When a warning condition occurs, it is reported in on of the STATUS* registers and, if unmasked, the nFLT2 output is driven low. The nFLT2 indication for warning is cleared by a successful SPI read of the corresponding status register. Once cleared, warning indication is not repeated until the warning condition is removed and reapplied. For example, in an over temperature warning condition, after reading/clearing the bit the temperature must cool down to the normal operating range and then heat up again to the over temperature warning threshold for the error flag to be reasserted. The status bit always indicates the current state of the warning, and is not cleared until the error condition is removed. The Fault error class is used to report critical fault conditions. Fault errors have the ability to shut down the gate driver when they occur. When a fault condition occurs, it is reported in one of the STATUS* registers and, if unmasked, the nFLT1 output is driven low. Many faults have a corresponding configuration bit that enables the user to select the functional safe state of the driver when that fault occurs when the fault is not masked. These bits are in the CFG* registers, with bit names that start with "FS_STATE_". Throughout this document, the FS_STATE locations are indicated in the functional description of the block where the fault is monitored. The available options for the output state, depending on the fault, are PL (OUTL pulled low), PH (OUTH pulled high), or no action (gate driver output ignores the fault and continues normal operation). Faults are cleared when the condition is removed, and the CONTROL2[CLR_STAT_REG] bit (CONTROL2) is written. Fault indication reasserts as long as the fault condition exists and is unmasked. #GUID-2684F8A6-04AD-49B9-B2C2-ED345674CFC4/T4885753-84 provides an extensive list and details for the available faults and warnings.

DESAT detection function and function diagnostic Power transistor OCP, SCP, and TSD comparators and comparator diagnostics Power transistor high voltage clamping circuit detection and function diagnostics Active Miller clamp diagnostic Undervoltage Lockout (UVLO) and Overvoltage Lockout (OVLO) UVLO functions are implemented for all three gate driver power supplies VCC1, VCC2, and VEE2. The VCC1 UVLO/OVLO ensures a valid supply is connected for the required logic interface. The UVLO/OVLO for VCC2 and VEE2 ensures valid supplies based on the type of transistor used. The UVLO function prevents overheating damage to the IGBTs/MOSFETs from being under-driven. The OVLO functions are implemented to prevent gate oxide degradation (shortened lifetime) of the IGBTs/MOSFETs from an over-voltage supply at turned on. The device powers up when a valid VCC1 supply (VIT+(UVLO1) < VVCC1 < VIT+(OVLO1)) and non-UV VCC2 supply (VVCC2 > VIT+(UVLO2)) are connected. The driver outputs are high impedance until the valid supplies are connected and the internal supplies are in regulation. While the driver output is high impedance, the output to the gate of the external power switch is held low with a passive and active pulldown circuit. See the section for more details. Once valid supplies are connected and internal supplies are valid, the output state is determined by the Enable/Disable Driver command any fault conditions that exist. SPI communication is unavailable while VCC1 is lower than the UVLO1 threshold. The OVLO and UVLO functions are enabled/disabled using the following bits: CFG1[UV1_DIS] for VCC1 UVLO, CFG1[OV1_DIS] for VCC1 OVLO, CFG4[UV2_DIS] for VCC2 UVLO,CFG4[OV2_DIS] for VCC2 OVLO, and CFG4[UVOV3_EN] for both the OVLO and UVLO for VEE2. The UVLO and OVLO thresholds for VCC1, VCC2 and VEE2 are programmable in order to customize the driver for different types of power transistors. Use the CFG1[UVLO1_LEVEL] and CFG1[OVLO1_LEVEL] (for VCC1), CFG7[UVLO2TH] and CFG7[OVLO2TH] (for VCC2), and CFG7[UVLO3TH] and CFG7[IOVLO3TH] (for VEE2) bits to set the desired threshold. See CFG1 and CFG7. The fault status for the OVLO and UVLO function are located in STATUS2[UVLO1_FAULT] for VCC1 UVLO, STATUS2[OVLO1_FAULT] for VCC1 OVLO, STATUS3[UVLO2_FAULT] for VCC2 UVLO, STATUS3[OVLO2_FAULT] for VCC2 OVLO, STATUS3[UVLO3_FAULT] for VEE2 UVLO, and STATUS3[OVLO3_FAULT] for VEE2 OVLO. See STATUS2 and STATUS3 for additional details. The timing diagrams for the VCC1 and VCC2 UVLO and OVLO functions are shown in and , respectively. The VEE2 timing diagram is shown in . Illustration of UVLO and OVLO timing schemes of VCC1. Illustration of UVLO and OVLO timing schemes of VCC2 Illustration of UVLO and OVLO timing schemes of VEE2 Built-In Self Test (BIST) Analog Built-In Self Test (ABIST) The device automatically runs diagnostics on all of the under-voltage and over-voltage comparators monitoring VCC1, VCC2, VEE2, and internal regulators during the power up process. During the self-test of the comparators, an over-voltage and under-voltage condition is simulated. The actual monitored voltage rails remain unchanged and the disturbance is not observable. A failure in the ABIST for the primary side sets the STATUS2[BIST_PRI_FAULT] (STATUS2) and for the secondary side sets the SATUS4[BIST_SEC_FAULT] (STATUS4). Function BIST In addition to the automatic analog BIST, there are BIST diagnostics available for DESAT, the PWM signal (INP) check, STP, Gate Voltage Monitoring, SCP/OCP, PS_TSD, and VCECLP. Details for the functionality of each of these tests are provided in the CONTROL1 (CONTROL1) and CONTROL2 (CONTROL2) register bit descriptions. Clock Monitor The device integrates clock monitor functions to identify clock faults during operation. The Clock monitor detects internal oscillator failures: Oscillator clock stuck high or stuck low Clock frequency is out of range ±30% The clock monitor is enabled during a power-up event after the power-on reset is released. The clocks on the primary side and secondary side are monitored. In the event of a clock fault on the primary side, the STATUS4[CLK_MON_SEC_FAULT] bit (STATUS4 ) is set, the driver is forced to the state determined by the CFG11[FS_STATE_CLK_MON_SEC_FAULT] bit (CFG11) and, if unmasked, the nFLT1 output pulls low. In the event of a clock fault on the secondary side, the STATUS2[CLK_MON_PRI_FAULT] bit (STATUS2 ) is set, and, if unmasked, the nFLT1 output pulls low. The secondary side clock monitor has no effect on the gate driver output state. Clock Monitor Built-In Self Test The clock monitor circuit integrates a diagnostic that checks the integrity of the monitoring circuit. The diagnostic is run automatically during the startup process. Additionally, a simulated clock monitor fault is generated by writing the CONTROL1[CLK_MON_CHK_PRI] bit () for the primary side and the CONTROL2[CLK_MON_CHK_SEC] bit () for the secondary side. When enabled, the enabled diagnostics emulates clock failure that causes a clock monitor fault. During this self-test, the actual oscillator frequency is not changed. CLAMP, OUTH, and OUTL Clamping Circuits Integrated diodes prevent the OUTH and CLAMP outputs from exceeding VCC2. The short circuit clamping function clamps the voltages at the driver output (OUTH) and active Miller clamp (CLAMP) outputs to be slightly higher than VCC2 during power switch short circuit conditions. The clamped gate voltage limits the short circuit current and prevents the IGBT/MOSFET gate from overvoltage breakdown or degradation. The internal diodes conduct up to 500 mA current for a duration of 10us, and a continuous current of 20mA. Use external Schottky diodes to improve current conduction capability, if needed. While VCC2 is unpowered, the gate of the external power switch is held off with an active pulldown circuit. If the OUTL suddenly rises due to ramping VCC2 during power up, the active pulldown function pulls the IGBT/MOSFET gate to the low state and maintains the OUTL voltage below VOUTSD. See for a drawing of the clamping circuits. CLAMP, OUTH, and OUTL Clamping Circuits Active Miller Clamp The Active Miller clamp function (CLAMP output) is used to prevent the power transistor from false turn-on due Miller capacitance induced current. The active Miller clamp adds a low impedance path between power transistor gate terminal and VEE2 to pull the gate of the external FET hard to VEE2, bypassing any external gate resistors. The Miller clamp engages when the OUTH voltage falls below the VCLPTH, which is selected using the CFG5[MCLPTH] bits (CFG5). Additionally, the Miller clamp is enabled/disabled using the CFG4[MCLP_DIS] bit (CFG4). The status of the Miller clamp is available in the STATUS3[MCLP_STATE] bit (STATUS3). If additional pulldown strength is required, the CLAMP output is configured to drive an external Miller clamp FET. Use the CFG4[MCLP_CFG] bit to select between the internal and external Miller clamp (CFG4). This option can be configured through the register. The implementation block diagram and timing scheme are shown in and respectively. Block diagram of implementation of internal Miller clamp function. Block diagram of implementation of external Miller clamp function. Timing scheme of implementation of Miller clamp function. DESAT based Short Circuit Protection (DESAT) DESAT protection prevents the power transistor from damage in case of short circuit faults. The DESAT input monitors the VCEsat (IGBT)/VDSon (MOSFET) through an external resistor and diode network (R1, C1, D1 and D2 in ). The D1 diode protects the driver IC from high voltage when the power transistor is OFF. The resistor, R1, limits the negative voltage applied on the DESAT input during switching transitions. While the power FET is ON, an internal current source, ICHG, forward biases the DESAT diode and dumps into the collector/drain of the external power switch. Under normal conditions, the VCEsat/VDSon is less than a few volts, however, during short circuit faults the VCEsat/VDSon may rise up to the DC bus voltage when the power transistor operates in the linear region. In this situation, the D1 diode is reverse biased, so the internal current source charges the blanking capacitor (C1) Once the voltage on the DESAT input charges up to the selected threshold (VDESATth),the driver output is pulled into the safe state defined by the CFG10[FS_STATE_DESAT_SCP] bit (CFG10), the fault is indicated in the STATUS3[DESAT_FAULT] (STATUS3), and, if unmasked, the NFLT1 output pulls low. The turn-off of the driver output during a DESAT fault is selectable between normal, soft turn-off (STO), or two-level turnoff (2LTO) dictated by the CFG5[2LTOFF_STO_EN] bits (CFG5). See the and for additional details on STO and 2LTO, respectively. The blanking capacitor is fully discharged at the falling edge of the PWM signal using the internal discharge current (IDCHG). In addition to the blanking time, DESAT is deglitched to prevent false triggering during transitions. The deglitch is selectable using the CFG4[DESAT_DEGLITCH] bit (CFG4). The DESAT threshold is selectable using the CFG5[DESATTH] bits (CFG5), and the DESAT charging current (ICHG) is selectable, using the CFG5[DESAT_CHG_CURR] bits (CFG5), to control the blanking time (tDS_BLK). The discharge current is enabled/disabled using the CFG5[DESAT_DCHG_EN] bit (CFG5). The DESAT protection function is enabled or disabled using the CFG4[DESAT_EN] bit (CFG4). The implementation diagram and timing schemes of DESAT based short circuit protection are presented in and respectively. See the section for details on selecting the R1, C1, and D1 values. Block diagram of implementation of DESAT protection function. Timing scheme of implementation of DESAT protection function (safe state is LOW). Shunt Resistor based Overcurrent Protection (OCP) and Short Circuit Protection (SCP) The device designates three AI* inputs (AI2, AI4, AI6) to support shunt resistor based OCP and SCP in order to support up to three power transistors in parallel. Shunt resistor based OCP/SCP protections are intended for power transistors with integrated current sense FETs. The mirrored power transistor currents is fed into a resistor, and the voltage is monitored at the AI* input. Once the voltage at the AI* input exceeds the threshold programmed using CFG6[OCTH] (for OCP, CFG6) or CFG6[SCTH] (for SCP, CFG6), the fault is indicated in the STATUS3[OC_FAULT] (for OCP, STATUS3) or the STATUS3[SC_FAULT] (for SCP, STATUS3), and if unmasked, nFLT1x is pulled low and the driver output goes to the state defined by CFG10[FS_STATE_OCP] (for OCP, CFG10) or CFG10[FS_STATE_SCP] (for SCP, CFG10). The turn-off of the driver output during a OCP or SCP fault is selectable between normal, soft turn-off (STO), or two-level turnoff (2LTO) dictated by the CFG5[2LTOFF_STO_EN] bits (CFG5). See the Soft Turn-off (STO) and Two-Level Turn-Off for additional details on STO and 2LTO, respectively. A blanking time is used for both OCP and SCP to prevent unwanted false protection triggering during transitions and is selectable in CFG6[OC_BLK] (for OCP, CFG6)) or CFG6[SC_BLK] (for SCP, CFG6)). Once the blanking time expires, any SCP/OCP fault must exist for the deglitch time before the fault is registered. Enable/disable which AI* inputs are to be used for SCP/OCP using the DOUTCFG[AI*OCSC_EN] bits (DOUTCFG). The OCP and SCP functions are enabled for the selected AI* inputs using the CFG4[OCP_DIS] (for OCP, CFG4) and CFG4[SCP_DIS] (for SCP, CFG4) bits. Please note that if AI6 is to be used for OCP/SCP, the CFG8[AI_ASC_MUX] bit (CFG8) must be configured as an ADC input. The implementation diagram and timing schemes for the shunt resistor based OCP and SCP are presented in Block diagram of implementation of shunt resistor based OCP and SCP functions and Timing scheme of implementation of shunt resistor based OCP function (safe state is LOW) respectively. Block diagram of implementation of shunt resistor based OCP and SCP functions. Timing scheme of implementation of shunt resistor based OCP function (safe state is LOW) Current sources are available for AI2, AI4, and AI6 as open pin diagnosis tools. Enable the current sources using the CFG3[ITO2_EN] bit (CFG3). When enabled, the AI2, AI4, AI6 inputs are pulled high if left unconnected. Temperature Monitoring and Protection for the Power Transistors The device designates three AI* inputs (AI1, AI3, AI5) to support NTC diode sensing for up to three power transistors in parallel. The temperature protection is intended for power transistors with integrated temperature sensing diodes. The AI* input provides a zero-TC current that biases the integrated diode, and the voltage is monitored at the AI* input. The bias current is controlled using CFG3[ITO1_EN] (CFG3) as a master enable, and then using CFG3[AI_IZTC_SEL] (CFG3) to select which AI* output is to receive the bias current. Once the voltage at the AI* input falls below the threshold programmed using CFG6[TSD_PS] (CFG6), the fault is indicated in the STATUS3[PS_TSD_FAULT] (STATUS3), and if unmasked, nFLT1 is pulled low and the driver output goes to the state defined by CFG10[FS_STATE_PS_TSD] (CFG10). The turn-off of the driver output during an PS_TSD fault is selectable between normal, soft turn-off (STO), or two-level turnoff (2LTO) dictated by the CFG5[2LTOFF_STO_EN] bits. See the and for additional details on STO and 2LTO, respectively. Any PS_TSD fault must exist for the deglitch time programmed using the CFG4[PS_TSD_DEGLITCH] bits (CFG4) before the fault is registered. Enable/disable which AI* inputs are to be used for PS_TSD using the DOUTCFG[AI*PS_TSD_EN] bits (DOUTCFG). The temperature monitoring function is enabled for the selected AI* inputs using the CFG4[PS_PS_TEMP_EN] bit (CFG4). Please note that if AI5 is to be used for power switch temperature monitoring, the CFG8[AI_ASC_MUX] bit (CFG8) must be configured as an ADC input. The implementation diagram and timing schemes of PS_TSD are presented in and respectively. Block diagram of implementation of PS temperature monitoring function. Timing scheme of implementation of PS_TSD function. Active High Voltage Clamping (VCECLP) The active high voltage clamping feature protects power transistors from over-voltage damage during switching transitions, while reducing the power dissipated in the external TVS clamp diodes protecting the power FET. During turn-off, the VCECLP input is monitored. Once the VCE of the FET increases to turn on the external TVS diode, the RC network on the VCECLP input is charged up. Once the VCECLP input reaches the clamp threshold (VCECLPTH), OUTL drive strength changes to the ISTO setting in order to slow down the turn off and reduce the overshoot. The high voltage clamping remains active for a predefined time tVCECLP_HLD. The OV condition is reported in STATUS3[VCEOV_FAULT] (STATUS3). The implementation and timing diagrams for the active high voltage clamping are presented in and , respectively. The VCECLP feature is enabled/disabled using the CFG4[VCECLP_EN] bit (CFG4). Block diagram of implementation of active high voltage clamping function. Timing scheme of implementation of active high voltage clamping function. Two-Level Turn-Off The two-level turn-off (2LTOFF) function limits the transistor current during shutoff during certain fault conditions. The 2LTOFF function is enabled for PS_OC, PS_SC, PS_TSD, and/or DESAT faults using the CF5[2LTOFF_STO_EN] bits (CFG5). When 2LTOFF is triggered, the gate of the power transistor is controlled to operate the transistor in the linear region where the channel current is controlled by the voltage level on the gate terminal. The power transistor current is reduced by controlling the gate voltage to a intermediate voltage, or plateau voltage, (V2LOFF) for t2LOFF, and then ramping the gate down to turn the power transistor off. While 2LTOFF is active, OUTL sinks current to discharge the gate capacitor of the power switch to the plateau voltage. The gate discharge current is programmable using the CFG8[GD_2LOFF_CURR] bits (CFG8). The plateau voltage level and duration are configured using the CFG8[GD_2LOFF_VOLT] and CFG8[GD_2LOFF_TIME] bits (CFG8), respectively. After holding the plateau voltage for the programmed time, the gate is discharged fully using the soft turn-off current or pulled low as normal with the OUTL driver. Enable the soft turn off current using the CFG8[GD_2LOFF_STO_EN] bit (CFG8). The implementation diagram and timing scheme are presented in and , respectively. Block diagram of implementation of two-level turn-off function Timing scheme of implementation of two-level turn-off function Soft Turn-Off (STO) The soft turn-off (STO) function prevents power transistors from OV damage because of parasitic loop inductance induced voltage spikes on VCE. The STO slows down the turn-off process that to limit the di/dt rate, and thus limits the loop inductance induced voltage spikes. During STO, the OUTL drive strength is reduced to the threshold programmed using the CFG5[STO_CURR] bits (CFG5). The STO function is enabled for PS_OC, PS_SC, PS_TSD, and/or DESAT faults using the CF5[2LTOFF_STO_EN] bits (CFG5). Thermal Shutdown (TSD) and Temperature Warning (TWN) of Driver IC C 20210503 Updated secondary side TSD behavior to clarify the functions operation. yes Gate driver temperature monitoring prevents driver IC from damage during overheating conditions. Both the primary and secondary sides of the driver utilize thermal warning and shutdown comparators to help prevent damage due to high temperatures. When a thermal warning is detected on the primary side, the STATUS1[GD_TWN_PRI_FAULT] (STATUS1) is set and, if unmasked, the nFLT2 output is pulled low. If over temperature event is detected on the primary side, the device transitions to the RESET state where the driver output is held low. Once the device cools, the device must be reconfigured as described in the Programming section before enabling the driver output. When a thermal warning is detected on the secondary side, the STATUS4[GD_TWN_SEC_FAULT](STATUS4) is set and, if unmasked, the nFLT2 output is pulled low. When a thermal shutdown is detected on the secondary side, the driver is disabled, , the STATUS4[GD_TSD_SEC_FAULT] (STATUS4), is set and, if unmasked, the nFLT1 output is pulled low. The status register flag for TSD may not be set depending on the timing of the thermal event, however the nFLT1 indicator will be pulled low. In the case of the secondary thermal shutdown event, the clock monitor and inter-die communication faults will likely be indicated. This is expected behavior due to the secondary side being shutdown and not communicating to the primary side. Once the driver cools and communication is reestablished, the device must be reconfigured as described in the Programming section before turning on the driver output. A blanking time is inserted to prevent unwanted false triggering of the protection circuits. Timing scheme of implementation of driver IC TSD function. Active Short Circuit Support (ASC) C 20210503 Added information about gate monitoring during secondary side ASC operation. yes The active short circuit (ASC) function allows the system to force the state of the power transistor regardless of the PWM input. For cases where the main MCU is not available due to fault or otherwise, a secondary control circuit drives the ASC_EN input high to force the output of the device to the state defined by the ASC input. For the primary side, two dedicated inputs are available for the ASC control. The ASC control is also available on the secondary side using the AI5 and AI6 inputs. To configure the device with the secondary ASC function, the CFG8[AI_ASC_MUX] bit (CFG8) must be configured in ASC mode. In this configuration, AI5 is ASC_EN and AI6 is the ASC input. The operation is identical to what is described for the primary side. Please note that if AI5/AI6 are to be used for the ASC function they are unavailable for OCP/SCP and PS temperature monitoring. When using the secondary side ASC, it is possible that the GM_FAULT will be set (when enabled) if the IN+ state is different than the ASC state. There will be no fault action taken, but the STATUS3[GM_FAULT] will be set. The implementation flow of ASC function is presented in . This implementation assumes both primary and secondary ASC are used. The secondary ASC covers the failure mode where VCC1 power is down. The primary and secondary ASC functions can be used independently. If both ASC functions are enabled, the secondary ASC has highest priority. The ASC functions are available in all operation states, assuming there is a valid power supply (VCC1 and VCC2 for ASC/ASC_EN or VCC2 for AI5/AI6). ASC implementation Flowchart ASC implementation logic. Shoot-Through Protection (STP) The shoot through protection function (STP) provides an additional layer of protection from shoot through conditions due to incorrect PWM commands from MCU. The output of the driver uses IN+ and the complementary PWM signal provided to the IN- input to set the output state of the driver. Both the IN+ and IN- inputs are deglitched by tGLITCH, which is programmable using CFG1[IO_DEGLITCH] bits (CFG1). There are two available version of STP, IN+/IN- safety interlock and automatic dead-time. The safety interlock function is enabled by setting the CFG1[TDEAD] bits (CFG1) to 0b000000 (tDEAD = 0). When using the safety interlock STP, if IN+ and IN- are both high at the same time, a shoot-through condition (STP fault) is detected. During an STP fault, the STATUS2[STP_FAULT] bit (STATUS2 ) is set, and, if unmasked, the nFLT1 output pulls low. The output of the driver is forced to the state defined by CFG3[FS_STATE_STP_FAULT] (CFG3 ). When the tDEAD is non-zero (CFG1[TDEAD] ≠ 0b000000, dead time is added to the falling edge of IN- by the device. In these cases, when IN+ goes high, the device waits until the deglitched falling edge of IN-, then OUTH pulls high tDEAD after the deglitched IN- is low. The implementation diagram and timing schemes are presented in and respectively. Block diagram of implementation of STP function. Timing scheme of implementation of STP function. Gate Voltage Monitoring and Status Feedback The integrity of the PWM channel is monitored end to end using two checks. The first check monitors the communication across the isolation channel. The received state on the secondary side is communicated back o the primary side to ensure the two match. If there is a mismatch between the IN+ state and the received IN+ state, the STATUS1[PWM_COMP_CHK_FAULT] bit (STATUS1) is set, if unmasked, nFLT1 pulls low, and the driver output is forced ot the state defined by CFG3[FS_STATE_PWM_CHK] (CFG3). The second check monitors the actual gate voltage of the power transistor to ensure the gate is in the correct state. The monitored gate voltage is first converted to logic state and indicated in the STATUS3[GM_STATE] bit (STATUS3). The converted gate voltage logic state is then compared with the input PWM (IN+) signal. The mismatch of the two signals causes a gate voltage monitor fault condition where the STATUS3[GM_FAULT] bit (STATUS3 ) is set, the driver output is forced to the state defined by CFG10[FS_STATE_GM] (CFG10 ), and, if unmasked, nFLT1 pulls low. Blanking time relative to the driver outputs is used to prevent false reporting of the gate voltage monitor error during driver transitions. During 2LTOFF transitions, the blanking time starts after the 2LTOFF plateau timer expires in order to prevent false GM faults during the transition. Alternatively, the GM fault may be disabled during STO and 2LTOFF using the CFG5[GM_STO2LTO_DIS] bit (CFG5). The blanking time is adjustable using the CFG4[GM_BLK] bits (CFG4). Additionally, the gate monitoring function may be disabled entirely using the CFG4[GM_EN] bit (CFG4). The implementation block diagram and timing schemes are presented in and . Block diagram of implementation of gate voltage monitor function. Timing scheme of implementation of gate voltage monitor function. VGTH Monitor C 20210503 Corrected equation. yes The VGTH Monitor function is used to measure the gate threshold voltage of the power transistor during power up. When enabled using the CONTROL2[VGTH_MEAS] bit (CONTROL2), the switch between DESAT and OUTH is turned on. A constant current source charges the gate capacitance of the power transistor and the gate voltage ramps up gradually. Once the channel starts to conduct, the gate voltage is naturally held at the threshold voltage level as the power transistor in a diode configuration. After the blanking time, tdVGTHM, the integrated ADC samples the gate voltage, and reports the measurement in register ADCDATA8. The measurement is actually a divided down version (divided by 8) of the gate voltage. The actual threshold voltage is calculated as: VGTH = VADCDATA8 × 8 This measurement is then used by the MCU to judge the health of the power transistor. VGTH monitoring circuit current flow while charging the gate capacitance VGTH monitoring circuit current flow while the power transistor is in diode configuration Cyclic Redundancy Check (CRC) the device uses a cyclic redundancy check (CRC) to ensure data integrity for the configuration of the device while the driver output is active, the SPI communications (both transmitted and received), and the internal non-volatile memory that store the trim information that ensures the performance of the device. The CRC represents the remainder of a process analogous to polynomial long division, where the protected data is divided by the polynomial. The device uses the CRC8 polynomial X8 + X2 + X + 1 with a 0xFF initialization (to catch leading 0 errors) for its calculations. Calculating CRC The calculation process begins by initializing the command frame by XORing it with the current CRC (0xFF for the very first command frame). Next, the XOR'd value is divided by the polynomial. The result is used as the CRC for the next frame. Repeat the process until all of the frames are run through the calculation. Note that the CRC is updated internal with every 16-bits, so the actual read/write command byte must be included in the calculation. See for an example calculation. Configuration Data CRC C 20210503 Corrected CONTROL2 bit name in list yes When the device transitions to the ACTIVE state, the contents of configuration and control registers are protected by CRC engine. The configuration CRC is enabled using the CFG8[CRC_DIS] bit (CFG8). The registers protected by the CRC include: CFG1 - CFG11 ADCCFG DOUTCFG GD_ADDRESS[GD_ADDR] (no MSB) SPITEST CONTROL1 CONTROL2, excluding the MSB (CONTROL2[CLR_STAT_REG]) The CRC fault detection is performed every tCRCCFG (typically 2 ms). If the calculated CRC8 checksum for the configuration registers does not match the CRC8 checksum calculated upon entering the Active state, the STATUS2[CFG_CRC_PRI_FAULT] (for a primary side CRC fail, STATUS2) or the STATUS4[CFG_CRC_SEC_FAULT] (for a secondary side CRC fail, STATUS4) bit is set and, if unmasked, the nFLT1 output goes low. Additionally, for the secondary side CRC failure, the driver output is forced to the state defined by CFG11[FS_STATE_CFG_CRC_SEC_FAULT] (CFG11). Diagnostics for the CRC check are available. Use the CONTROL1[CFG_CRC_CHK_PRI] (CONTROL1) to induce a CRC error on the primary side. CONTROL2[CFG_CRC_CHK_SEC] (CONTROL2) to induce a CRC error on the secondary side. Writing to any of the "RESERVED" bits in the configuration registers also induces a CRC fault. Configuration Data CRC Check Timing SPI Transfer Write/Read CRC The CRC checks for SPI transfer are continuously updated as SPI traffic is received/ sent. The CRC is updated with every 16-bits that are received. An example of calculating the SPI CRC for a sent command is given in . In this set of commands, we are updating the configuration for CFG1 and then doing a CRC comparison on that command. Example of CRC Calculation While Updating CFG1 Command Purpose CRC Before CRC_After 0xFC00 Change the SPI address pointer to CFG1 register 0xFF (Initialized) 0x3F 0xFA58 Update the high byte with 0x58 configuration 0x3F 0x23 0xFB2A Update the low byte with 0x2A configuration 0x23 0xC4 0xFC13 Change the SPI address point to CRCDATA register 0xC4 0x28 0xFA30 Update the CRC_TX bits with the calculated CRC 0x28 0x30 (written to the CRC_TX bits) Calculating CRC for a Set of Commands SDI CRC Check The SDI CRC checksum data is continuously calculated as SPI data frames are received. Once the MCU writes to the to CRCDATA[CRC_TX] bits (CRCDATA). The write to these bits triggers a comparison of the data in the CRC_TX bits with the internally calculated CRC. Once the comparison is complete, the CRC calculation logic is reset (reset value = 0xFF). When there is a mismatch between CRC_TX data and CRC calculated internally, the STATUS2[SPI_FAULT] bit (STATUS2) is and, if unmasked, the nFLT1 output pulls low. Additionally, the output of the driver is forced to the state programmed in CFG3[FS_STATE_SPI_FAULT] (CFG3). SDO CRC Check The SDO CRC checksum is continuously calculated as data is clocked out of SDO. The resulting CRC is stored in the CRCDATA[CRC_RX] bits. The bits are updated whenever nCS transitions from low to high. The CRC calculation logic is reset (reset value = 0xFF) when the CRC_RX bits are read or when the CONTROL1[CLR_SPI_CRC] bit is written. Note that the CRC_RX bits are reset immediately with the read, and the next CRC_RX value begins its calculation while clocking out of the CRC_RX bits. This means the received CRC_RX must be included in the next CRC calculation (i.e. the received CRC_RX is the first byte to be xor'd with the 0xFF reset value). TRIM CRC Check After each power up, the device performs a TRIM CRC check on the internal non-volatile memory on both the primary and secondary sides. If the calculated CRC8 checksum does not match the CRC8 checksum stored in the internal TRIM memory, the STATUS2[TRIM_CRC_PRI_FAULT] (for a primary side CRC fail, STATUS2) or the STATUS4[TRIM_CRC_SEC_FAULT] (for a secondary side CRC fail, STATUS4) bit is set and, if unmasked, the nFLT1 output goes low. Additionally for the secondary side CRC failure, the driver output is forced to the state defined by CFG11[FS_STATE_TRIM_CRC_SEC_FAULT] (CFG11). Device Functional Modes The overall operation mode transition diagram is presented in . The current state of the device is read in the STATUS1[OPM] bits (STATUS1). Note that these bits are only readable in the Configuration 2 and Active states. State 1: RESET State 2: Configuration 1 State 3: Configuration 2 State 4: Active Operation mode diagram during normal operation State 1: RESET When a valid power supply is first applied to VCC1, the device enters the RESET state. In the RESET state, the device does not respond to commands from MCU, the driver outputs (OUTL and OUTH) are both high impedance, the registers are reset to the default values, and all of the built In Self Tests (BIST) run. The nFLTx outputs are held low until a power source is connected to VCC2, all of the automatic BISTs complete, and the device transitions to the Configuration 1 state. After transitioning from Reset, the device only returns to the Reset state if the power is cycled, or if the primary side over temperature is detected. The secondary over temperature event does not cause the state transition to RESET unless the primary side also detects the over temperature event. State 2: Configuration 1 Once all of the BIST complete, and communication is established from the primary to the secondary side, the device transitions to the Configuration 1 state. This is indicated when the nFLT* outputs are pulled high. In this state, the address for the device is programmable by the MCU. See the Device Addressing section for details on how to program the SPI address for the device. The driver output (OUTL) is pulled low in this state. Once the address is programmed, the CONFIG_IN command (see ) must be sent to transition to the Configuration 2 state. Note that in Daisy Chain configurations, the CFG_IN must be sent to the devices one-by-one because the SDO output is not enabled until a valid addressed command is sent. This can be done by sending a full frame of 6 CFG_IN commands six times or, alternatively, send a CFG_IN to the first device as a single command followed by CFG_IN, NOP as the second frame, followed by CFG_IN, NOP, NOP as the third frame, and so on to enable the SDO output on all devices and send them to Configuration 2. This process only needs to be done once per power cycle unless an invalid address (non-0x0) is sent. State 3: Configuration 2 When a valid CONFIG_IN command (see ) is received, the device transitions to the Configuration 2 state. In this state, the device configuration is programmable by the MCU via the SPI interface. All of the configuration registers are available for write. The STATUS registers are updated with the status of the device and the nFLT* outputs will indicate any unmasked faults. The ADC does not operate in the Configuration 2 state. The driver output (OUTL) is pulled low in this state. Send a DRV_EN command (see ) to transition to the Active state and enable the driver output. State 4: Active C 20210503 Corrected CONTROL2 bit name yes Upon receiving a valid DRV_EN command, the device transitions to the Active state. In this state, the STATUS2[DRV_EN_RCVD] bit (STATUS2) is set to '1', the CRC for the configuration registers is calculated and stored, SPI writes to most registers are disabled, and the driver outputs are enabled to follow the IN+/IN- inputs, assuming there is no fault condition. All of the registers are Read Only, with the exception of CONTROL2[CLR_STAT_REG], CFG8[IOUT_SEL], and CFG8[CRC_DIS]. Any writes to any other registers/ bits are ignored. The device remains in Active mode until the SW_RESET command is sent, a DRV_DIS command followed by a CONFIG_IN is sent, or a primary side thermal shutdown fault occurs. The SW_RESET command disables the driver and resets all registers except for the driver address, while the DRV_DIS command disables the driver while leaving the register contents intact. Programming SPI Communication Programming of the device is done through the SPI serial communication slave interface by an external MCU. The SPI communication follows a 16-bit protocol, utilizing specific command data frames, and uses an active-low chip select input (nCS) and communicates at rates up to 4MHz. The communication frame starts with the nCS falling edge and ends with nCS rising edge. While nCS is high, the SPI interface is held in reset, and the SDO output is high impedance. The SPI clock idles at 0 (CPOL=0) and clocks the SDI/SDO data (CPHA=1) on the falling edge. The device supports three SPI bus configurations: independent slave configuration, daisy chain configuration, and a new address oriented configuration. System Configuration of SPI Communication The system is configured in one of the three SPI modes: Regular SPI configuration (), Daisy Chain configuration (), and Address-based onfiguration (). Independent Slave Configuration The Independent Slave configuration is shown in . In this mode, the CLK input, SDI input, and SDO outputs for all devices on the SPI bus are shared. The MCU drives the nCS input for the device that is to be addressed. The drawback to this approach is that a separate GPIO for each driver in the system (up to 12 for dual inverter systems) is required of the MCU, but it does allow random access to any device in the system. The message frame is shown in System configuration of regular SPI configuration SPI message frame for Independent Slave and Address-based configurations Daisy Chain Configuration The Daisy Chain configuration is shown in . In this configuration, the MCU MOSI connects to the SDI of the first device and the MISO connects to the SDO of the last device. The SDO of each of the device connects to the SDI of the next device in the system (excluding the last device). The system effectively becomes a communication shift register. During communication, the host continuously clocks in data for all the devices in the system while holding the nCS pin low. While the nCS input is low, the SDO shifts data out as the data is clocked into the SDI shift register as shown in . Once nCS is pulled high, the 16-bits in the SDI register are latched and acted upon by the device. This configuration drastically reduces the number of GPIOs required, but it does not allow random access to the devices. System configuration of daisy chain SPI configuration SPI message frame daisy chain SPI configuration Address-based Configuration The Address-based configuration provides significant flexibility to the system design. This configuration is similar to the Independent Slave configuration in that all of the CLK, SDO, and SDI connections are shared between all devices (shown in ). Additionally, the nCS input is also shared. This reduces the GPIO requirement on the MCU to one, similar to Daisy Chain, but also allows random access like the Independent Slave configuration. The Address-based configuration is done by defining each device in the system with a unique address. See the Device Addressing section for details on how to address the devices in the system. The message frame is shown in System configuration for Address-based SPI Communication Scheme SPI Data Frame The SPI data frame is composed of 16bits. The timing scheme and format of a data frame is shown in and . Timing scheme of SPI communication 16-bit of SPI data frame. The 16-bit data frame includes three data fields: chip address (CHIP_ADDR), command type (CMD), and an 8-bit data (DATA). The chip address (CHIP_ADDR) bits are used, regardless of the system configuration. However, when using the Daisy Chain or Independent Slave configurations, 0x0 or 0xF is used for all of the devices in the system. In Address-based configuration, the devices are individually addressed, and all devices respond to 0x0 and 0xF. Note that SDO is high impedance until it receives a command with the programmed device address. Once receiving the valid addressed command, the SDO is driven to send out data. When an invalid addressed command or 0xF (broadcast address) is received, the SDO returns to high impedance, thereby allowing other devices to take control of the shared MISO (SDO) bus. There are 10 command types used by the device, defined in .

The SPI engine utilizes three separate commands in order to program these registers. The process involves first setting the register to be written to by using the WR_RA command. All subsequent writes will go to this register address until the WR_RA command is sent again, or the device is reset. Use the WRH command to write the "high" byte of the register (bits 15:8) and use the WRL command to write the "low" byte of the register (bits 7:0). The WRH and WRL commands can be sent in any order. Additionally, it is not necessary to write both bytes of the register. If only the "low" byte needs modification, a WRL write is all that is required. It is not necessary to send a WRH command as well. Reading a Register The process for reading a register is less steps than that of a write command. To read a register, simply use the RD_DATA command to program the device with the register to be read. The full 16-bit data is clocked out during the next SPI transaction. The next SPI transaction could be another command (RD_DATA or WR_RA, for example), or simply a NOP (no operation command). Never send a RD_DATA command to the broadcast address (0xF) while in the Address-based configuration. This will cause all devices on the bus to responds simultaneously and the data will be corrupted. It is ok to use 0xF in the other modes as the traffic is handled by another mechanism.

Additionally, SPI bits are referred to in the following convention: REGNAME[BITNAME] Functional Block Diagram Functional Block Diagram Feature Description Power Supplies The device uses three external supplies for power. VCC1 supplies the low voltage primary side that interfaces with the controller. VCC2 and VEE2 provide the gate drive supplies for the power FET. In addition, there are 3 integrated supplies (VREG1, VREG2, and VREF) used to power internal circuits. VCC1 VCC1 supports an input range of 3V to 5.5V in order to support both 3.3V and 5V controller signaling. VCC1 is monitored with both an undervoltage and overvoltage comparator circuit to ensure valid operation. UV and OV conditions of VCC1 are recorded in STATUS2[UVLO1_FAULT] and STATUS2[OVLO_FAULT1], respectively(STATUS2). See the Undervoltage Lockout (UVLO) and Overvoltage Lockout (OVLO) section for more specifics regarding the OV and UV functions. VCC2 VCC2 operates within an input range of 15V and 30V, allowing for use in IGBT and SiC applications. VCC2 is monitored with both an undervoltage and overvoltage comparator circuit to ensure valid operation. UV and OV conditions of VCC2 are recorded in STATUS3[UVLO2_FAULT] and STATUS3[OVLO2_FAULT], respectively (STATUS3 ). See the Undervoltage Lockout (UVLO) and Overvoltage Lockout (OVLO) section for more specifics regarding the OV and UV functions. VEE2 VEE2 operates with an input range of -12V to 0V, allowing a negative gate bias on the power FET during turn-off in both IGBT and SiC applications. This prevents the power FET from unintentionally turning on due to current inducted from the Miller effect. For operation with a unipolar supply, connect VEE2 to GND2. VEE2 is monitored with both an undervoltage and overvoltage comparator circuit to ensure valid operation. UV and OV conditions of VEE2 are recorded in STATUS3[UVLO3_FAULT] and STATUS3[OVLO3_FAULT], respectively (STATUS3 ). See the Undervoltage Lockout (UVLO) and Overvoltage Lockout (OVLO) section for more specifics regarding the OV and UV functions. VREG1 VREG1 is internally generated from VCC1. VREG1 regulates to 1.8V, and supplies internal circuits on the primary side. VREG1 requires a 4.7µF bypass capacitance from VREG1 to GND1 for proper operation. The current out of VREG1 is limited and this current limit is monitored. If the current limit is active for the deglitch time, a internal regulation overcurrent fault is recorded in STATUS2[VREG1_ILIMIT_FAULT]. If unmasked, nFLT1 goes low. Additionally, VREG1 is monitored for both undervoltage and overvoltage conditions. Any VREG1 UV fault is recorded in STATUS2[INT_REG_PRI_FAULT] (STATUS2 ). Any OV condition on VREG1 causes the VREG1 output to latch off and shuts down the device. This action results in a secondary communication failure, which shuts down the driver output according to CFG10[FS_STATE_INT_COMM_SEC] bit (CFG10). The VCC1 and VCC2 power must be recycled in order to restart the device. VREG2 VREG2 is internally generated from VCC2. VREG2 regulates to 1.8V with respect to VEE2, and supplies internal circuits on the secondary side. VREG2 requires a 4.7µF bypass capacitance from VREG2 to VEE2 for proper operation. The current out of VREG2 is limited and this current limit is monitored. If the current limit is active for the deglitch time, a internal regulation overcurrent fault is recorded in STATUS3[VREG2_ILIMIT_FAULT] (STATUS3). If unmasked, nFLT1 goes low. Additionally, VREG2 is monitored for both undervoltage and overvoltage conditions. Any VREG2 OV/UV faults are recorded in STATUS3[INT_REG_SEC_FAULT] (STATUS3 ). Any OV condition on VREG2 causes the VREG2 output to latch off and shuts down the driver output. The VCC2 power must be recycled in order to restart the driver output. Additionally, the driver must be reconfigured to ensure correct operation. VREF VREF is the reference for the ADC. VREF requires a 4V supply for the ADC to function properly. The error of the VREF translates directly to the error at the ADC. VREF is selectable to be powered internally, or alternatively, an external precision reference may be used to enhance the accuracy of the ADC. Use the CFG8[VREF_SEL] (CFG8) bit to select between the internal and external reference. The current out of VREF is limited and this current limit is monitored. If the current limit is active for the deglitch time, a internal regulation overcurrent fault is detected. Additionally, VREF is monitored for both undervoltage and overvoltage conditions. When any VREFILIM and/or OV/UV faults occur, the faults are recorded in STATUS5[ADC_FAULT] (STATUS5). If unmasked, nFLT1 goes low. Other Internal Rails There are several internal rails that are used to power the device. All of the internal rails are monitored for OV and UV conditions. Any OV/UV faults are recorded in the STATUS2[INT_REG_PRI_FAULT] (STATUS2) and STATUS3[INT_REG_SEC_FAULT] (STATUS3) bits. Bootstrap (VBST) and charge pump circuits generate the 4.5V power supply for the high side NMOS of internal driver stage. The implementation diagram is shown in . The external cap on BST is charged to 4.5V while OUTL is on (MN2 is on). While OUTH is on (MN1 is on), the capacitor voltage is stacked above OUTH and supplies the gate drive for the high-side NMOS. Under most conditions, the bootstrap circuit is used and the timing operates as shown in . However, for slow switching frequencies at high duty cycles the external capacitor may not be able to charge enough during the OUTH off time to supply the gate drive for the entire on-time. In these conditions, the charge pump circuit is used to hold the voltage across the bootstrap capacitor. . Implementation diagram of bootstrap and charge pump circuits. Timing diagram of bootstrap circuit. Driver Stage C 20210503 Updated drive strength to 30 A to align with typical value yes The driver stage is an integrated, 30-A current buffer. The high output drive capability enables the device to directly drive power transistors with current ratings up to 1000A without an external buffer. The drive strength is selectable to 16.7%, 33%, or 100% using CFG8[IOUT_SEL] (CFG8). The output drive is split, enabling users to customize rise and fall times independently. . Integrated ADC for Front-End Analog (FEA) Signal Processing A 10bit ADC is integrated to enable the user to digitally monitor up to 6 analog input voltages (AI*). Additionally, the junction temperature of the device is available as well as an input for measuring the VTH of the power FET. The ADC has a full scale voltage range of 0 to 3.6V, requiring 4V at VREF (either internal or external). The ADC conversions are aligned with the INP signal to ensure the least amount of noise coupling from the switching transients of the power transistors (TI proprietary). Once a conversion is complete, the conversion results are transferred to the primary side of the device with inter-die communication and the result is stored in the ADCDATA* registers. The last ADC result is always available in the register. Every ADC conversion is recorded with time stamp information for that conversion. The time stamp is the INP cycle where the measurement occurs. Once the ADC and the driver are enabled, the time stamp increments with every INP low to high edge. If a fault occurs, or the duty cycle is such that a transition is not seen on INP, the TIME_STAMP does not update. VAI* = VADC (in decimal) × 3.519mV Die Temperature (C) = VADC(in decimal) * 0.7015°C - 198.36 The AI* inputs are configurable by the user to enable/disable bias currents and comparator monitoring AI1, AI3, and AI5 are specially designed to monitor the temperature diode that is integrated into the power FET module, while A2, A4, and A6 are designed to measure the power FET current, typically from an integrated sense FET in the module. However, the inputs are not required to be used in these functions, and are configurable to measure any voltage up to 3.6V regardless of the source. The implementation of ADC sensing circuits is presented in . Block diagram of implementation of ADC processing for the case where three power transistors are connected in parallel. AI* Setup AI5 and AI6 are dual purpose inputs. By default, these inputs are configured to be control inputs for the secondary side ASC function (see the ASC section for more details). If AI5 and AI6 are to be used as current sense/ temperature sense/ ADC inputs, write CFG8[AI_ASC_MUX] = 1 (CFG8) to disable the ASC functionality. All of the AI* inputs have current sources that may be enabled using the CFG3[ITO1_EN] bit (CFG3) for AI1,3,5 and the CFG3[ITO2_EN] bit (CFG3) for the AI2,4,6. Additionally, the AI1, AI3, and AI5 inputs are designed with a zero-temperature coefficient bias current (IZTC) to bias the NTC diodes integrated into the external power switch module. Use CFG3[AI_IZTC_SEL] bits (CFG3) to enable the required bias currents for the application. The AI* inputs require an RC filter for most accurate results. See the section for details on selecting the correct RC values. ADC Setup and Sampling Modes The ADC is enabled/disabled with SPI communication to CFG7[ADC[ADC_EN] (CFG7). The 6 AI inputs as well as the die junction temperature are selectable to measure with the ADC. Additionally, the channels are selectable as to when it is samples with respect to the INP switching cycle. Use the ADCCFG[ADC_ON_CH_SEL_*] bits (ADCCFG) to select the channels to be measured while INP is high. The sampling order for the PWM ON cycle round robin is: AI1, AI3, AI5, AI2, AI4, AI6, Die Temp. Use the ADCCFG[ADC_OFF_CH_SEL_*] bits () to select the channels to be measured while INP is low. Use the CFG7[ADC_SAMP_MODE] bits (ADCCFG) to select one of 3 sampling modes for the ADC. Three modes are available to ensure the least amount of switching noise in the measurement. The three modes are Center Aligned mode (CFG7[ADC_SAMP_MODE]=0b00), where each selected channel is sampled in the center of the ON/OFF time of the INP input (depending on the setting), Edge Mode (CFG7[ADC_SAMP_MODE] = 0b01), where the ADC conversions begin after rising or falling edge (depending on the setting), and Hybrid mode (CFG7[ADC_SAMP_MODE] = 0b10), which is a combination of both modes. The maximum INP frequency supported in order to get at least one full ADC conversion per PWM cycle is 30kHz. Center Sampling Mode When using Center sampling mode (CFG7[ADC_SAMP_MODE]=0b00), the center is calculated for the ON or OFF time on INP (depending on the channel selection setup) based on the previous switching cycle. One channel is sampled during each ON or OFF time depending on the channel selections. The timing for Center mode is illustrated in the following figures. ADC center sampling mode ADC center sample mode timing chart Edge Sampling Mode Edge Mode (CFG7[ADC_SAMP_MODE] = 0b01) begins the ADC conversions based on the INP edge. When INP transitions, the ADC begins conversions for the round robin after the programmable delay time (programmed using CFG7[ADC_SAMP_DLY]). The channels selected for the PWM ON time are sampled after a rising edge of INP, while the channels selected for the PWM OFF time are sampled after a falling edge. The round robin continues until the next edge of INP. The timing for Edge mode is illustrated in the following figures. ADC edge sampling mode ADC Edge sampling mode timing chart Hybrid Mode Hybrid Mode (CFG7[ADC_SAMP_MODE]=0b10) operates using a combination of the modes. Center mode is used until the INP period is greater than the hybrid period (thybrid) when edge mode is used. The timing for Hybrid mode is illustrated in the following figures. ADC Hybrid sampling mode timing chart DOUT Functionality The device also provides an analog feedback functionality for the ADC for applications that do not want to maintain continuous SPI communication. When enabled, the DOUT output provides a PWM signal with a duty cycle proportional to the signal that is selected to be monitored. Any of the AI* inputs and the TJ are available for monitoring on the DOUT output. As there is only one DOUT output, only one channel is selectable. Typically, DOUT is either directly monitored by the MCU, or run through an RC filter to convert it to an analog voltage that may be digitized and monitored by the host controller. In order to use the DOUT function, the nFLT2 pin must be reconfigured to select the DOUT functionality using the CFG1[NFLT2_DOUT_MUX] bit (CFG1 ). When the DOUT mode is selected, any warning or fault that was selected to report to nFLT2 now reports to nFLT1 automatically. Additionally, the frequency of DOUT is selectable between 4 options using the DOUTCFG[FREQ_DOUT] bits (DOUTCFG ). Select the channel to be monitored, using the DOUTCFG[DOUT_TO_AI*] bits (for the AI* inputs, DOUTCFG ) or the DOUTCFG[DOUT_TO_TJ] bit (DOUTCFG ) for the die junction temperature. If multiple channels are selected in the register, the duty cycle constantly changes as the ADC cycles through each channel read. It is recommended to only select one channel at a time for the DOUT function. In addition to this setup, the ADC must be enabled and setup correctly to read the desired channel to be monitored. See the ADC section for details on configuring the ADC. If a fault occurs that stops the driver output and ADC measurements, the DOUT output continues and represents the last good ADC reading. Fault and Warning Classification The device integrates extensive error detection and monitoring features. These features allow the design of a robust system that protects against a variety of system related failure modes. When one of the monitored warnings or faults occurs, if unmasked, the nFLT1 output (for faults) or the nFLT2 output (for warnings) pulls low. All of the fault and warning bits have corresponding configuration bits that allow the user to mask the error or fault from showing up on the nFLT* output. The naming convention is straightforward. The mask bit is in a CFG* register and is named the same as the fault with the addition of an "_P". For example, a power FET short circuit current fault is indicated in the register bit STATUS3[SC_FAULT] (STATUS3)and the mask bit is CFG9[SC_FAULT_P] (CFG9). Throughout this document, the different warning/error bit locations are indicated in the functional description of the block where the warning/fault is monitored. When masked, the nFLT* indication does not occur, but the STATUS* bits still indicate the warning/fault condition. The device classifies error events into two categories, Warnings and Faults, and takes different device actions depending on the error classification. The Warning error class is used to report non-critical fault conditions. Warning errors are only reported with no action taken to affect the gate driver output or any other block. When a warning condition occurs, it is reported in on of the STATUS* registers and, if unmasked, the nFLT2 output is driven low. The nFLT2 indication for warning is cleared by a successful SPI read of the corresponding status register. Once cleared, warning indication is not repeated until the warning condition is removed and reapplied. For example, in an over temperature warning condition, after reading/clearing the bit the temperature must cool down to the normal operating range and then heat up again to the over temperature warning threshold for the error flag to be reasserted. The status bit always indicates the current state of the warning, and is not cleared until the error condition is removed. The Fault error class is used to report critical fault conditions. Fault errors have the ability to shut down the gate driver when they occur. When a fault condition occurs, it is reported in one of the STATUS* registers and, if unmasked, the nFLT1 output is driven low. Many faults have a corresponding configuration bit that enables the user to select the functional safe state of the driver when that fault occurs when the fault is not masked. These bits are in the CFG* registers, with bit names that start with "FS_STATE_". Throughout this document, the FS_STATE locations are indicated in the functional description of the block where the fault is monitored. The available options for the output state, depending on the fault, are PL (OUTL pulled low), PH (OUTH pulled high), or no action (gate driver output ignores the fault and continues normal operation). Faults are cleared when the condition is removed, and the CONTROL2[CLR_STAT_REG] bit (CONTROL2) is written. Fault indication reasserts as long as the fault condition exists and is unmasked. #GUID-2684F8A6-04AD-49B9-B2C2-ED345674CFC4/T4885753-84 provides an extensive list and details for the available faults and warnings.

DESAT detection function and function diagnostic Power transistor OCP, SCP, and TSD comparators and comparator diagnostics Power transistor high voltage clamping circuit detection and function diagnostics Active Miller clamp diagnostic Undervoltage Lockout (UVLO) and Overvoltage Lockout (OVLO) UVLO functions are implemented for all three gate driver power supplies VCC1, VCC2, and VEE2. The VCC1 UVLO/OVLO ensures a valid supply is connected for the required logic interface. The UVLO/OVLO for VCC2 and VEE2 ensures valid supplies based on the type of transistor used. The UVLO function prevents overheating damage to the IGBTs/MOSFETs from being under-driven. The OVLO functions are implemented to prevent gate oxide degradation (shortened lifetime) of the IGBTs/MOSFETs from an over-voltage supply at turned on. The device powers up when a valid VCC1 supply (VIT+(UVLO1) < VVCC1 < VIT+(OVLO1)) and non-UV VCC2 supply (VVCC2 > VIT+(UVLO2)) are connected. The driver outputs are high impedance until the valid supplies are connected and the internal supplies are in regulation. While the driver output is high impedance, the output to the gate of the external power switch is held low with a passive and active pulldown circuit. See the section for more details. Once valid supplies are connected and internal supplies are valid, the output state is determined by the Enable/Disable Driver command any fault conditions that exist. SPI communication is unavailable while VCC1 is lower than the UVLO1 threshold. The OVLO and UVLO functions are enabled/disabled using the following bits: CFG1[UV1_DIS] for VCC1 UVLO, CFG1[OV1_DIS] for VCC1 OVLO, CFG4[UV2_DIS] for VCC2 UVLO,CFG4[OV2_DIS] for VCC2 OVLO, and CFG4[UVOV3_EN] for both the OVLO and UVLO for VEE2. The UVLO and OVLO thresholds for VCC1, VCC2 and VEE2 are programmable in order to customize the driver for different types of power transistors. Use the CFG1[UVLO1_LEVEL] and CFG1[OVLO1_LEVEL] (for VCC1), CFG7[UVLO2TH] and CFG7[OVLO2TH] (for VCC2), and CFG7[UVLO3TH] and CFG7[IOVLO3TH] (for VEE2) bits to set the desired threshold. See CFG1 and CFG7. The fault status for the OVLO and UVLO function are located in STATUS2[UVLO1_FAULT] for VCC1 UVLO, STATUS2[OVLO1_FAULT] for VCC1 OVLO, STATUS3[UVLO2_FAULT] for VCC2 UVLO, STATUS3[OVLO2_FAULT] for VCC2 OVLO, STATUS3[UVLO3_FAULT] for VEE2 UVLO, and STATUS3[OVLO3_FAULT] for VEE2 OVLO. See STATUS2 and STATUS3 for additional details. The timing diagrams for the VCC1 and VCC2 UVLO and OVLO functions are shown in and , respectively. The VEE2 timing diagram is shown in . Illustration of UVLO and OVLO timing schemes of VCC1. Illustration of UVLO and OVLO timing schemes of VCC2 Illustration of UVLO and OVLO timing schemes of VEE2 Built-In Self Test (BIST) Analog Built-In Self Test (ABIST) The device automatically runs diagnostics on all of the under-voltage and over-voltage comparators monitoring VCC1, VCC2, VEE2, and internal regulators during the power up process. During the self-test of the comparators, an over-voltage and under-voltage condition is simulated. The actual monitored voltage rails remain unchanged and the disturbance is not observable. A failure in the ABIST for the primary side sets the STATUS2[BIST_PRI_FAULT] (STATUS2) and for the secondary side sets the SATUS4[BIST_SEC_FAULT] (STATUS4). Function BIST In addition to the automatic analog BIST, there are BIST diagnostics available for DESAT, the PWM signal (INP) check, STP, Gate Voltage Monitoring, SCP/OCP, PS_TSD, and VCECLP. Details for the functionality of each of these tests are provided in the CONTROL1 (CONTROL1) and CONTROL2 (CONTROL2) register bit descriptions. Clock Monitor The device integrates clock monitor functions to identify clock faults during operation. The Clock monitor detects internal oscillator failures: Oscillator clock stuck high or stuck low Clock frequency is out of range ±30% The clock monitor is enabled during a power-up event after the power-on reset is released. The clocks on the primary side and secondary side are monitored. In the event of a clock fault on the primary side, the STATUS4[CLK_MON_SEC_FAULT] bit (STATUS4 ) is set, the driver is forced to the state determined by the CFG11[FS_STATE_CLK_MON_SEC_FAULT] bit (CFG11) and, if unmasked, the nFLT1 output pulls low. In the event of a clock fault on the secondary side, the STATUS2[CLK_MON_PRI_FAULT] bit (STATUS2 ) is set, and, if unmasked, the nFLT1 output pulls low. The secondary side clock monitor has no effect on the gate driver output state. Clock Monitor Built-In Self Test The clock monitor circuit integrates a diagnostic that checks the integrity of the monitoring circuit. The diagnostic is run automatically during the startup process. Additionally, a simulated clock monitor fault is generated by writing the CONTROL1[CLK_MON_CHK_PRI] bit () for the primary side and the CONTROL2[CLK_MON_CHK_SEC] bit () for the secondary side. When enabled, the enabled diagnostics emulates clock failure that causes a clock monitor fault. During this self-test, the actual oscillator frequency is not changed. CLAMP, OUTH, and OUTL Clamping Circuits Integrated diodes prevent the OUTH and CLAMP outputs from exceeding VCC2. The short circuit clamping function clamps the voltages at the driver output (OUTH) and active Miller clamp (CLAMP) outputs to be slightly higher than VCC2 during power switch short circuit conditions. The clamped gate voltage limits the short circuit current and prevents the IGBT/MOSFET gate from overvoltage breakdown or degradation. The internal diodes conduct up to 500 mA current for a duration of 10us, and a continuous current of 20mA. Use external Schottky diodes to improve current conduction capability, if needed. While VCC2 is unpowered, the gate of the external power switch is held off with an active pulldown circuit. If the OUTL suddenly rises due to ramping VCC2 during power up, the active pulldown function pulls the IGBT/MOSFET gate to the low state and maintains the OUTL voltage below VOUTSD. See for a drawing of the clamping circuits. CLAMP, OUTH, and OUTL Clamping Circuits Active Miller Clamp The Active Miller clamp function (CLAMP output) is used to prevent the power transistor from false turn-on due Miller capacitance induced current. The active Miller clamp adds a low impedance path between power transistor gate terminal and VEE2 to pull the gate of the external FET hard to VEE2, bypassing any external gate resistors. The Miller clamp engages when the OUTH voltage falls below the VCLPTH, which is selected using the CFG5[MCLPTH] bits (CFG5). Additionally, the Miller clamp is enabled/disabled using the CFG4[MCLP_DIS] bit (CFG4). The status of the Miller clamp is available in the STATUS3[MCLP_STATE] bit (STATUS3). If additional pulldown strength is required, the CLAMP output is configured to drive an external Miller clamp FET. Use the CFG4[MCLP_CFG] bit to select between the internal and external Miller clamp (CFG4). This option can be configured through the register. The implementation block diagram and timing scheme are shown in and respectively. Block diagram of implementation of internal Miller clamp function. Block diagram of implementation of external Miller clamp function. Timing scheme of implementation of Miller clamp function. DESAT based Short Circuit Protection (DESAT) DESAT protection prevents the power transistor from damage in case of short circuit faults. The DESAT input monitors the VCEsat (IGBT)/VDSon (MOSFET) through an external resistor and diode network (R1, C1, D1 and D2 in ). The D1 diode protects the driver IC from high voltage when the power transistor is OFF. The resistor, R1, limits the negative voltage applied on the DESAT input during switching transitions. While the power FET is ON, an internal current source, ICHG, forward biases the DESAT diode and dumps into the collector/drain of the external power switch. Under normal conditions, the VCEsat/VDSon is less than a few volts, however, during short circuit faults the VCEsat/VDSon may rise up to the DC bus voltage when the power transistor operates in the linear region. In this situation, the D1 diode is reverse biased, so the internal current source charges the blanking capacitor (C1) Once the voltage on the DESAT input charges up to the selected threshold (VDESATth),the driver output is pulled into the safe state defined by the CFG10[FS_STATE_DESAT_SCP] bit (CFG10), the fault is indicated in the STATUS3[DESAT_FAULT] (STATUS3), and, if unmasked, the NFLT1 output pulls low. The turn-off of the driver output during a DESAT fault is selectable between normal, soft turn-off (STO), or two-level turnoff (2LTO) dictated by the CFG5[2LTOFF_STO_EN] bits (CFG5). See the and for additional details on STO and 2LTO, respectively. The blanking capacitor is fully discharged at the falling edge of the PWM signal using the internal discharge current (IDCHG). In addition to the blanking time, DESAT is deglitched to prevent false triggering during transitions. The deglitch is selectable using the CFG4[DESAT_DEGLITCH] bit (CFG4). The DESAT threshold is selectable using the CFG5[DESATTH] bits (CFG5), and the DESAT charging current (ICHG) is selectable, using the CFG5[DESAT_CHG_CURR] bits (CFG5), to control the blanking time (tDS_BLK). The discharge current is enabled/disabled using the CFG5[DESAT_DCHG_EN] bit (CFG5). The DESAT protection function is enabled or disabled using the CFG4[DESAT_EN] bit (CFG4). The implementation diagram and timing schemes of DESAT based short circuit protection are presented in and respectively. See the section for details on selecting the R1, C1, and D1 values. Block diagram of implementation of DESAT protection function. Timing scheme of implementation of DESAT protection function (safe state is LOW). Shunt Resistor based Overcurrent Protection (OCP) and Short Circuit Protection (SCP) The device designates three AI* inputs (AI2, AI4, AI6) to support shunt resistor based OCP and SCP in order to support up to three power transistors in parallel. Shunt resistor based OCP/SCP protections are intended for power transistors with integrated current sense FETs. The mirrored power transistor currents is fed into a resistor, and the voltage is monitored at the AI* input. Once the voltage at the AI* input exceeds the threshold programmed using CFG6[OCTH] (for OCP, CFG6) or CFG6[SCTH] (for SCP, CFG6), the fault is indicated in the STATUS3[OC_FAULT] (for OCP, STATUS3) or the STATUS3[SC_FAULT] (for SCP, STATUS3), and if unmasked, nFLT1x is pulled low and the driver output goes to the state defined by CFG10[FS_STATE_OCP] (for OCP, CFG10) or CFG10[FS_STATE_SCP] (for SCP, CFG10). The turn-off of the driver output during a OCP or SCP fault is selectable between normal, soft turn-off (STO), or two-level turnoff (2LTO) dictated by the CFG5[2LTOFF_STO_EN] bits (CFG5). See the Soft Turn-off (STO) and Two-Level Turn-Off for additional details on STO and 2LTO, respectively. A blanking time is used for both OCP and SCP to prevent unwanted false protection triggering during transitions and is selectable in CFG6[OC_BLK] (for OCP, CFG6)) or CFG6[SC_BLK] (for SCP, CFG6)). Once the blanking time expires, any SCP/OCP fault must exist for the deglitch time before the fault is registered. Enable/disable which AI* inputs are to be used for SCP/OCP using the DOUTCFG[AI*OCSC_EN] bits (DOUTCFG). The OCP and SCP functions are enabled for the selected AI* inputs using the CFG4[OCP_DIS] (for OCP, CFG4) and CFG4[SCP_DIS] (for SCP, CFG4) bits. Please note that if AI6 is to be used for OCP/SCP, the CFG8[AI_ASC_MUX] bit (CFG8) must be configured as an ADC input. The implementation diagram and timing schemes for the shunt resistor based OCP and SCP are presented in Block diagram of implementation of shunt resistor based OCP and SCP functions and Timing scheme of implementation of shunt resistor based OCP function (safe state is LOW) respectively. Block diagram of implementation of shunt resistor based OCP and SCP functions. Timing scheme of implementation of shunt resistor based OCP function (safe state is LOW) Current sources are available for AI2, AI4, and AI6 as open pin diagnosis tools. Enable the current sources using the CFG3[ITO2_EN] bit (CFG3). When enabled, the AI2, AI4, AI6 inputs are pulled high if left unconnected. Temperature Monitoring and Protection for the Power Transistors The device designates three AI* inputs (AI1, AI3, AI5) to support NTC diode sensing for up to three power transistors in parallel. The temperature protection is intended for power transistors with integrated temperature sensing diodes. The AI* input provides a zero-TC current that biases the integrated diode, and the voltage is monitored at the AI* input. The bias current is controlled using CFG3[ITO1_EN] (CFG3) as a master enable, and then using CFG3[AI_IZTC_SEL] (CFG3) to select which AI* output is to receive the bias current. Once the voltage at the AI* input falls below the threshold programmed using CFG6[TSD_PS] (CFG6), the fault is indicated in the STATUS3[PS_TSD_FAULT] (STATUS3), and if unmasked, nFLT1 is pulled low and the driver output goes to the state defined by CFG10[FS_STATE_PS_TSD] (CFG10). The turn-off of the driver output during an PS_TSD fault is selectable between normal, soft turn-off (STO), or two-level turnoff (2LTO) dictated by the CFG5[2LTOFF_STO_EN] bits. See the and for additional details on STO and 2LTO, respectively. Any PS_TSD fault must exist for the deglitch time programmed using the CFG4[PS_TSD_DEGLITCH] bits (CFG4) before the fault is registered. Enable/disable which AI* inputs are to be used for PS_TSD using the DOUTCFG[AI*PS_TSD_EN] bits (DOUTCFG). The temperature monitoring function is enabled for the selected AI* inputs using the CFG4[PS_PS_TEMP_EN] bit (CFG4). Please note that if AI5 is to be used for power switch temperature monitoring, the CFG8[AI_ASC_MUX] bit (CFG8) must be configured as an ADC input. The implementation diagram and timing schemes of PS_TSD are presented in and respectively. Block diagram of implementation of PS temperature monitoring function. Timing scheme of implementation of PS_TSD function. Active High Voltage Clamping (VCECLP) The active high voltage clamping feature protects power transistors from over-voltage damage during switching transitions, while reducing the power dissipated in the external TVS clamp diodes protecting the power FET. During turn-off, the VCECLP input is monitored. Once the VCE of the FET increases to turn on the external TVS diode, the RC network on the VCECLP input is charged up. Once the VCECLP input reaches the clamp threshold (VCECLPTH), OUTL drive strength changes to the ISTO setting in order to slow down the turn off and reduce the overshoot. The high voltage clamping remains active for a predefined time tVCECLP_HLD. The OV condition is reported in STATUS3[VCEOV_FAULT] (STATUS3). The implementation and timing diagrams for the active high voltage clamping are presented in and , respectively. The VCECLP feature is enabled/disabled using the CFG4[VCECLP_EN] bit (CFG4). Block diagram of implementation of active high voltage clamping function. Timing scheme of implementation of active high voltage clamping function. Two-Level Turn-Off The two-level turn-off (2LTOFF) function limits the transistor current during shutoff during certain fault conditions. The 2LTOFF function is enabled for PS_OC, PS_SC, PS_TSD, and/or DESAT faults using the CF5[2LTOFF_STO_EN] bits (CFG5). When 2LTOFF is triggered, the gate of the power transistor is controlled to operate the transistor in the linear region where the channel current is controlled by the voltage level on the gate terminal. The power transistor current is reduced by controlling the gate voltage to a intermediate voltage, or plateau voltage, (V2LOFF) for t2LOFF, and then ramping the gate down to turn the power transistor off. While 2LTOFF is active, OUTL sinks current to discharge the gate capacitor of the power switch to the plateau voltage. The gate discharge current is programmable using the CFG8[GD_2LOFF_CURR] bits (CFG8). The plateau voltage level and duration are configured using the CFG8[GD_2LOFF_VOLT] and CFG8[GD_2LOFF_TIME] bits (CFG8), respectively. After holding the plateau voltage for the programmed time, the gate is discharged fully using the soft turn-off current or pulled low as normal with the OUTL driver. Enable the soft turn off current using the CFG8[GD_2LOFF_STO_EN] bit (CFG8). The implementation diagram and timing scheme are presented in and , respectively. Block diagram of implementation of two-level turn-off function Timing scheme of implementation of two-level turn-off function Soft Turn-Off (STO) The soft turn-off (STO) function prevents power transistors from OV damage because of parasitic loop inductance induced voltage spikes on VCE. The STO slows down the turn-off process that to limit the di/dt rate, and thus limits the loop inductance induced voltage spikes. During STO, the OUTL drive strength is reduced to the threshold programmed using the CFG5[STO_CURR] bits (CFG5). The STO function is enabled for PS_OC, PS_SC, PS_TSD, and/or DESAT faults using the CF5[2LTOFF_STO_EN] bits (CFG5). Thermal Shutdown (TSD) and Temperature Warning (TWN) of Driver IC C 20210503 Updated secondary side TSD behavior to clarify the functions operation. yes Gate driver temperature monitoring prevents driver IC from damage during overheating conditions. Both the primary and secondary sides of the driver utilize thermal warning and shutdown comparators to help prevent damage due to high temperatures. When a thermal warning is detected on the primary side, the STATUS1[GD_TWN_PRI_FAULT] (STATUS1) is set and, if unmasked, the nFLT2 output is pulled low. If over temperature event is detected on the primary side, the device transitions to the RESET state where the driver output is held low. Once the device cools, the device must be reconfigured as described in the Programming section before enabling the driver output. When a thermal warning is detected on the secondary side, the STATUS4[GD_TWN_SEC_FAULT](STATUS4) is set and, if unmasked, the nFLT2 output is pulled low. When a thermal shutdown is detected on the secondary side, the driver is disabled, , the STATUS4[GD_TSD_SEC_FAULT] (STATUS4), is set and, if unmasked, the nFLT1 output is pulled low. The status register flag for TSD may not be set depending on the timing of the thermal event, however the nFLT1 indicator will be pulled low. In the case of the secondary thermal shutdown event, the clock monitor and inter-die communication faults will likely be indicated. This is expected behavior due to the secondary side being shutdown and not communicating to the primary side. Once the driver cools and communication is reestablished, the device must be reconfigured as described in the Programming section before turning on the driver output. A blanking time is inserted to prevent unwanted false triggering of the protection circuits. Timing scheme of implementation of driver IC TSD function. Active Short Circuit Support (ASC) C 20210503 Added information about gate monitoring during secondary side ASC operation. yes The active short circuit (ASC) function allows the system to force the state of the power transistor regardless of the PWM input. For cases where the main MCU is not available due to fault or otherwise, a secondary control circuit drives the ASC_EN input high to force the output of the device to the state defined by the ASC input. For the primary side, two dedicated inputs are available for the ASC control. The ASC control is also available on the secondary side using the AI5 and AI6 inputs. To configure the device with the secondary ASC function, the CFG8[AI_ASC_MUX] bit (CFG8) must be configured in ASC mode. In this configuration, AI5 is ASC_EN and AI6 is the ASC input. The operation is identical to what is described for the primary side. Please note that if AI5/AI6 are to be used for the ASC function they are unavailable for OCP/SCP and PS temperature monitoring. When using the secondary side ASC, it is possible that the GM_FAULT will be set (when enabled) if the IN+ state is different than the ASC state. There will be no fault action taken, but the STATUS3[GM_FAULT] will be set. The implementation flow of ASC function is presented in . This implementation assumes both primary and secondary ASC are used. The secondary ASC covers the failure mode where VCC1 power is down. The primary and secondary ASC functions can be used independently. If both ASC functions are enabled, the secondary ASC has highest priority. The ASC functions are available in all operation states, assuming there is a valid power supply (VCC1 and VCC2 for ASC/ASC_EN or VCC2 for AI5/AI6). ASC implementation Flowchart ASC implementation logic. Shoot-Through Protection (STP) The shoot through protection function (STP) provides an additional layer of protection from shoot through conditions due to incorrect PWM commands from MCU. The output of the driver uses IN+ and the complementary PWM signal provided to the IN- input to set the output state of the driver. Both the IN+ and IN- inputs are deglitched by tGLITCH, which is programmable using CFG1[IO_DEGLITCH] bits (CFG1). There are two available version of STP, IN+/IN- safety interlock and automatic dead-time. The safety interlock function is enabled by setting the CFG1[TDEAD] bits (CFG1) to 0b000000 (tDEAD = 0). When using the safety interlock STP, if IN+ and IN- are both high at the same time, a shoot-through condition (STP fault) is detected. During an STP fault, the STATUS2[STP_FAULT] bit (STATUS2 ) is set, and, if unmasked, the nFLT1 output pulls low. The output of the driver is forced to the state defined by CFG3[FS_STATE_STP_FAULT] (CFG3 ). When the tDEAD is non-zero (CFG1[TDEAD] ≠ 0b000000, dead time is added to the falling edge of IN- by the device. In these cases, when IN+ goes high, the device waits until the deglitched falling edge of IN-, then OUTH pulls high tDEAD after the deglitched IN- is low. The implementation diagram and timing schemes are presented in and respectively. Block diagram of implementation of STP function. Timing scheme of implementation of STP function. Gate Voltage Monitoring and Status Feedback The integrity of the PWM channel is monitored end to end using two checks. The first check monitors the communication across the isolation channel. The received state on the secondary side is communicated back o the primary side to ensure the two match. If there is a mismatch between the IN+ state and the received IN+ state, the STATUS1[PWM_COMP_CHK_FAULT] bit (STATUS1) is set, if unmasked, nFLT1 pulls low, and the driver output is forced ot the state defined by CFG3[FS_STATE_PWM_CHK] (CFG3). The second check monitors the actual gate voltage of the power transistor to ensure the gate is in the correct state. The monitored gate voltage is first converted to logic state and indicated in the STATUS3[GM_STATE] bit (STATUS3). The converted gate voltage logic state is then compared with the input PWM (IN+) signal. The mismatch of the two signals causes a gate voltage monitor fault condition where the STATUS3[GM_FAULT] bit (STATUS3 ) is set, the driver output is forced to the state defined by CFG10[FS_STATE_GM] (CFG10 ), and, if unmasked, nFLT1 pulls low. Blanking time relative to the driver outputs is used to prevent false reporting of the gate voltage monitor error during driver transitions. During 2LTOFF transitions, the blanking time starts after the 2LTOFF plateau timer expires in order to prevent false GM faults during the transition. Alternatively, the GM fault may be disabled during STO and 2LTOFF using the CFG5[GM_STO2LTO_DIS] bit (CFG5). The blanking time is adjustable using the CFG4[GM_BLK] bits (CFG4). Additionally, the gate monitoring function may be disabled entirely using the CFG4[GM_EN] bit (CFG4). The implementation block diagram and timing schemes are presented in and .

VGTH Monitor C 20210503 Corrected equation. yes The VGTH Monitor function is used to measure the gate threshold voltage of the power transistor during power up. When enabled using the CONTROL2[VGTH_MEAS] bit (CONTROL2), the switch between DESAT and OUTH is turned on. A constant current source charges the gate capacitance of the power transistor and the gate voltage ramps up gradually. Once the channel starts to conduct, the gate voltage is naturally held at the threshold voltage level as the power transistor in a diode configuration. After the blanking time, tdVGTHM, the integrated ADC samples the gate voltage, and reports the measurement in register ADCDATA8. The measurement is actually a divided down version (divided by 8) of the gate voltage. The actual threshold voltage is calculated as: VGTH = VADCDATA8 × 8 This measurement is then used by the MCU to judge the health of the power transistor. VGTH monitoring circuit current flow while charging the gate capacitance VGTH monitoring circuit current flow while the power transistor is in diode configuration Cyclic Redundancy Check (CRC) the device uses a cyclic redundancy check (CRC) to ensure data integrity for the configuration of the device while the driver output is active, the SPI communications (both transmitted and received), and the internal non-volatile memory that store the trim information that ensures the performance of the device. The CRC represents the remainder of a process analogous to polynomial long division, where the protected data is divided by the polynomial. The device uses the CRC8 polynomial X8 + X2 + X + 1 with a 0xFF initialization (to catch leading 0 errors) for its calculations. Calculating CRC The calculation process begins by initializing the command frame by XORing it with the current CRC (0xFF for the very first command frame). Next, the XOR'd value is divided by the polynomial. The result is used as the CRC for the next frame. Repeat the process until all of the frames are run through the calculation. Note that the CRC is updated internal with every 16-bits, so the actual read/write command byte must be included in the calculation. See for an example calculation. Configuration Data CRC C 20210503 Corrected CONTROL2 bit name in list yes When the device transitions to the ACTIVE state, the contents of configuration and control registers are protected by CRC engine. The configuration CRC is enabled using the CFG8[CRC_DIS] bit (CFG8). The registers protected by the CRC include: CFG1 - CFG11 ADCCFG DOUTCFG GD_ADDRESS[GD_ADDR] (no MSB) SPITEST CONTROL1 CONTROL2, excluding the MSB (CONTROL2[CLR_STAT_REG]) The CRC fault detection is performed every tCRCCFG (typically 2 ms). If the calculated CRC8 checksum for the configuration registers does not match the CRC8 checksum calculated upon entering the Active state, the STATUS2[CFG_CRC_PRI_FAULT] (for a primary side CRC fail, STATUS2) or the STATUS4[CFG_CRC_SEC_FAULT] (for a secondary side CRC fail, STATUS4) bit is set and, if unmasked, the nFLT1 output goes low. Additionally, for the secondary side CRC failure, the driver output is forced to the state defined by CFG11[FS_STATE_CFG_CRC_SEC_FAULT] (CFG11). Diagnostics for the CRC check are available. Use the CONTROL1[CFG_CRC_CHK_PRI] (CONTROL1) to induce a CRC error on the primary side. CONTROL2[CFG_CRC_CHK_SEC] (CONTROL2) to induce a CRC error on the secondary side. Writing to any of the "RESERVED" bits in the configuration registers also induces a CRC fault. Configuration Data CRC Check Timing SPI Transfer Write/Read CRC The CRC checks for SPI transfer are continuously updated as SPI traffic is received/ sent. The CRC is updated with every 16-bits that are received. An example of calculating the SPI CRC for a sent command is given in . In this set of commands, we are updating the configuration for CFG1 and then doing a CRC comparison on that command. Example of CRC Calculation While Updating CFG1 Command Purpose CRC Before CRC_After 0xFC00 Change the SPI address pointer to CFG1 register 0xFF (Initialized) 0x3F 0xFA58 Update the high byte with 0x58 configuration 0x3F 0x23 0xFB2A Update the low byte with 0x2A configuration 0x23 0xC4 0xFC13 Change the SPI address point to CRCDATA register 0xC4 0x28 0xFA30 Update the CRC_TX bits with the calculated CRC 0x28 0x30 (written to the CRC_TX bits) Calculating CRC for a Set of Commands SDI CRC Check The SDI CRC checksum data is continuously calculated as SPI data frames are received. Once the MCU writes to the to CRCDATA[CRC_TX] bits (CRCDATA). The write to these bits triggers a comparison of the data in the CRC_TX bits with the internally calculated CRC. Once the comparison is complete, the CRC calculation logic is reset (reset value = 0xFF). When there is a mismatch between CRC_TX data and CRC calculated internally, the STATUS2[SPI_FAULT] bit (STATUS2) is and, if unmasked, the nFLT1 output pulls low. Additionally, the output of the driver is forced to the state programmed in CFG3[FS_STATE_SPI_FAULT] (CFG3). SDO CRC Check The SDO CRC checksum is continuously calculated as data is clocked out of SDO. The resulting CRC is stored in the CRCDATA[CRC_RX] bits. The bits are updated whenever nCS transitions from low to high. The CRC calculation logic is reset (reset value = 0xFF) when the CRC_RX bits are read or when the CONTROL1[CLR_SPI_CRC] bit is written. Note that the CRC_RX bits are reset immediately with the read, and the next CRC_RX value begins its calculation while clocking out of the CRC_RX bits. This means the received CRC_RX must be included in the next CRC calculation (i.e. the received CRC_RX is the first byte to be xor'd with the 0xFF reset value). TRIM CRC Check After each power up, the device performs a TRIM CRC check on the internal non-volatile memory on both the primary and secondary sides. If the calculated CRC8 checksum does not match the CRC8 checksum stored in the internal TRIM memory, the STATUS2[TRIM_CRC_PRI_FAULT] (for a primary side CRC fail, STATUS2) or the STATUS4[TRIM_CRC_SEC_FAULT] (for a secondary side CRC fail, STATUS4) bit is set and, if unmasked, the nFLT1 output goes low. Additionally for the secondary side CRC failure, the driver output is forced to the state defined by CFG11[FS_STATE_TRIM_CRC_SEC_FAULT] (CFG11). Feature Description Power Supplies The device uses three external supplies for power. VCC1 supplies the low voltage primary side that interfaces with the controller. VCC2 and VEE2 provide the gate drive supplies for the power FET. In addition, there are 3 integrated supplies (VREG1, VREG2, and VREF) used to power internal circuits. VCC1 VCC1 supports an input range of 3V to 5.5V in order to support both 3.3V and 5V controller signaling. VCC1 is monitored with both an undervoltage and overvoltage comparator circuit to ensure valid operation. UV and OV conditions of VCC1 are recorded in STATUS2[UVLO1_FAULT] and STATUS2[OVLO_FAULT1], respectively(STATUS2). See the Undervoltage Lockout (UVLO) and Overvoltage Lockout (OVLO) section for more specifics regarding the OV and UV functions. VCC2 VCC2 operates within an input range of 15V and 30V, allowing for use in IGBT and SiC applications. VCC2 is monitored with both an undervoltage and overvoltage comparator circuit to ensure valid operation. UV and OV conditions of VCC2 are recorded in STATUS3[UVLO2_FAULT] and STATUS3[OVLO2_FAULT], respectively (STATUS3 ). See the Undervoltage Lockout (UVLO) and Overvoltage Lockout (OVLO) section for more specifics regarding the OV and UV functions. VEE2 VEE2 operates with an input range of -12V to 0V, allowing a negative gate bias on the power FET during turn-off in both IGBT and SiC applications. This prevents the power FET from unintentionally turning on due to current inducted from the Miller effect. For operation with a unipolar supply, connect VEE2 to GND2. VEE2 is monitored with both an undervoltage and overvoltage comparator circuit to ensure valid operation. UV and OV conditions of VEE2 are recorded in STATUS3[UVLO3_FAULT] and STATUS3[OVLO3_FAULT], respectively (STATUS3 ).

VREG1 regulates to 1.8V, and supplies internal circuits on the primary side. VREG1 requires a 4.7µF bypass capacitance from VREG1 to GND1 for proper operation. The current out of VREG1 is limited and this current limit is monitored. If the current limit is active for the deglitch time, a internal regulation overcurrent fault is recorded in STATUS2[VREG1_ILIMIT_FAULT]. If unmasked, nFLT1 goes low. Additionally, VREG1 is monitored for both undervoltage and overvoltage conditions. Any VREG1 UV fault is recorded in STATUS2[INT_REG_PRI_FAULT] (STATUS2 ). Any OV condition on VREG1 causes the VREG1 output to latch off and shuts down the device. This action results in a secondary communication failure, which shuts down the driver output according to CFG10[FS_STATE_INT_COMM_SEC] bit (CFG10). The VCC1 and VCC2 power must be recycled in order to restart the device. VREG2 VREG2 is internally generated from VCC2. VREG2 regulates to 1.8V with respect to VEE2, and supplies internal circuits on the secondary side. VREG2 requires a 4.7µF bypass capacitance from VREG2 to VEE2 for proper operation.

Any OV condition on VREG2 causes the VREG2 output to latch off and shuts down the driver output. The VCC2 power must be recycled in order to restart the driver output. Additionally, the driver must be reconfigured to ensure correct operation. VREF VREF is the reference for the ADC. VREF requires a 4V supply for the ADC to function properly. The error of the VREF translates directly to the error at the ADC. VREF is selectable to be powered internally, or alternatively, an external precision reference may be used to enhance the accuracy of the ADC. Use the CFG8[VREF_SEL] (CFG8) bit to select between the internal and external reference. The current out of VREF is limited and this current limit is monitored. If the current limit is active for the deglitch time, a internal regulation overcurrent fault is detected. Additionally, VREF is monitored for both undervoltage and overvoltage conditions. When any VREFILIM and/or OV/UV faults occur, the faults are recorded in STATUS5[ADC_FAULT] (STATUS5). If unmasked, nFLT1 goes low. Other Internal Rails There are several internal rails that are used to power the device. All of the internal rails are monitored for OV and UV conditions. Any OV/UV faults are recorded in the STATUS2[INT_REG_PRI_FAULT] (STATUS2) and STATUS3[INT_REG_SEC_FAULT] (STATUS3) bits. Bootstrap (VBST) and charge pump circuits generate the 4.5V power supply for the high side NMOS of internal driver stage. The implementation diagram is shown in . The external cap on BST is charged to 4.5V while OUTL is on (MN2 is on). While OUTH is on (MN1 is on), the capacitor voltage is stacked above OUTH and supplies the gate drive for the high-side NMOS. Under most conditions, the bootstrap circuit is used and the timing operates as shown in . However, for slow switching frequencies at high duty cycles the external capacitor may not be able to charge enough during the OUTH off time to supply the gate drive for the entire on-time. In these conditions, the charge pump circuit is used to hold the voltage across the bootstrap capacitor. . Implementation diagram of bootstrap and charge pump circuits.

When any VREFILIM and/or OV/UV faults occur, the faults are recorded in STATUS5[ADC_FAULT] (STATUS5). If unmasked, nFLT1 goes low.CFG8STATUS5 Other Internal Rails There are several internal rails that are used to power the device. All of the internal rails are monitored for OV and UV conditions.

The output drive is split, enabling users to customize rise and fall times independently. .CFG8 Integrated ADC for Front-End Analog (FEA) Signal Processing A 10bit ADC is integrated to enable the user to digitally monitor up to 6 analog input voltages (AI*). Additionally, the junction temperature of the device is available as well as an input for measuring the VTH of the power FET. The ADC has a full scale voltage range of 0 to 3.6V, requiring 4V at VREF (either internal or external). The ADC conversions are aligned with the INP signal to ensure the least amount of noise coupling from the switching transients of the power transistors (TI proprietary). Once a conversion is complete, the conversion results are transferred to the primary side of the device with inter-die communication and the result is stored in the ADCDATA* registers. The last ADC result is always available in the register. Every ADC conversion is recorded with time stamp information for that conversion. The time stamp is the INP cycle where the measurement occurs. Once the ADC and the driver are enabled, the time stamp increments with every INP low to high edge. If a fault occurs, or the duty cycle is such that a transition is not seen on INP, the TIME_STAMP does not update. VAI* = VADC (in decimal) × 3.519mV Die Temperature (C) = VADC(in decimal) * 0.7015°C - 198.36 The AI* inputs are configurable by the user to enable/disable bias currents and comparator monitoring AI1, AI3, and AI5 are specially designed to monitor the temperature diode that is integrated into the power FET module, while A2, A4, and A6 are designed to measure the power FET current, typically from an integrated sense FET in the module. However, the inputs are not required to be used in these functions, and are configurable to measure any voltage up to 3.6V regardless of the source. The implementation of ADC sensing circuits is presented in . Block diagram of implementation of ADC processing for the case where three power transistors are connected in parallel. AI* Setup AI5 and AI6 are dual purpose inputs. By default, these inputs are configured to be control inputs for the secondary side ASC function (see the ASC section for more details). If AI5 and AI6 are to be used as current sense/ temperature sense/ ADC inputs, write CFG8[AI_ASC_MUX] = 1 (CFG8) to disable the ASC functionality. All of the AI* inputs have current sources that may be enabled using the CFG3[ITO1_EN] bit (CFG3) for AI1,3,5 and the CFG3[ITO2_EN] bit (CFG3) for the AI2,4,6. Additionally, the AI1, AI3, and AI5 inputs are designed with a zero-temperature coefficient bias current (IZTC) to bias the NTC diodes integrated into the external power switch module. Use CFG3[AI_IZTC_SEL] bits (CFG3) to enable the required bias currents for the application. The AI* inputs require an RC filter for most accurate results. See the section for details on selecting the correct RC values. ADC Setup and Sampling Modes The ADC is enabled/disabled with SPI communication to CFG7[ADC[ADC_EN] (CFG7). The 6 AI inputs as well as the die junction temperature are selectable to measure with the ADC. Additionally, the channels are selectable as to when it is samples with respect to the INP switching cycle. Use the ADCCFG[ADC_ON_CH_SEL_*] bits (ADCCFG) to select the channels to be measured while INP is high. The sampling order for the PWM ON cycle round robin is: AI1, AI3, AI5, AI2, AI4, AI6, Die Temp. Use the ADCCFG[ADC_OFF_CH_SEL_*] bits () to select the channels to be measured while INP is low. Use the CFG7[ADC_SAMP_MODE] bits (ADCCFG) to select one of 3 sampling modes for the ADC. Three modes are available to ensure the least amount of switching noise in the measurement. The three modes are Center Aligned mode (CFG7[ADC_SAMP_MODE]=0b00), where each selected channel is sampled in the center of the ON/OFF time of the INP input (depending on the setting), Edge Mode (CFG7[ADC_SAMP_MODE] = 0b01), where the ADC conversions begin after rising or falling edge (depending on the setting), and Hybrid mode (CFG7[ADC_SAMP_MODE] = 0b10), which is a combination of both modes. The maximum INP frequency supported in order to get at least one full ADC conversion per PWM cycle is 30kHz. Center Sampling Mode When using Center sampling mode (CFG7[ADC_SAMP_MODE]=0b00), the center is calculated for the ON or OFF time on INP (depending on the channel selection setup) based on the previous switching cycle. One channel is sampled during each ON or OFF time depending on the channel selections. The timing for Center mode is illustrated in the following figures. ADC center sampling mode ADC center sample mode timing chart Edge Sampling Mode Edge Mode (CFG7[ADC_SAMP_MODE] = 0b01) begins the ADC conversions based on the INP edge. When INP transitions, the ADC begins conversions for the round robin after the programmable delay time (programmed using CFG7[ADC_SAMP_DLY]). The channels selected for the PWM ON time are sampled after a rising edge of INP, while the channels selected for the PWM OFF time are sampled after a falling edge. The round robin continues until the next edge of INP. The timing for Edge mode is illustrated in the following figures. ADC edge sampling mode ADC Edge sampling mode timing chart Hybrid Mode Hybrid Mode (CFG7[ADC_SAMP_MODE]=0b10) operates using a combination of the modes. Center mode is used until the INP period is greater than the hybrid period (thybrid) when edge mode is used. The timing for Hybrid mode is illustrated in the following figures. ADC Hybrid sampling mode timing chart DOUT Functionality The device also provides an analog feedback functionality for the ADC for applications that do not want to maintain continuous SPI communication. When enabled, the DOUT output provides a PWM signal with a duty cycle proportional to the signal that is selected to be monitored. Any of the AI* inputs and the TJ are available for monitoring on the DOUT output. As there is only one DOUT output, only one channel is selectable. Typically, DOUT is either directly monitored by the MCU, or run through an RC filter to convert it to an analog voltage that may be digitized and monitored by the host controller. In order to use the DOUT function, the nFLT2 pin must be reconfigured to select the DOUT functionality using the CFG1[NFLT2_DOUT_MUX] bit (CFG1 ). When the DOUT mode is selected, any warning or fault that was selected to report to nFLT2 now reports to nFLT1 automatically. Additionally, the frequency of DOUT is selectable between 4 options using the DOUTCFG[FREQ_DOUT] bits (DOUTCFG ). Select the channel to be monitored, using the DOUTCFG[DOUT_TO_AI*] bits (for the AI* inputs, DOUTCFG ) or the DOUTCFG[DOUT_TO_TJ] bit (DOUTCFG ) for the die junction temperature. If multiple channels are selected in the register, the duty cycle constantly changes as the ADC cycles through each channel read. It is recommended to only select one channel at a time for the DOUT function. In addition to this setup, the ADC must be enabled and setup correctly to read the desired channel to be monitored. See the ADC section for details on configuring the ADC. If a fault occurs that stops the driver output and ADC measurements, the DOUT output continues and represents the last good ADC reading.

When enabled, the DOUT output provides a PWM signal with a duty cycle proportional to the signal that is selected to be monitored. Any of the AI* inputs and the TJ are available for monitoring on the DOUT output. As there is only one DOUT output, only one channel is selectable. Typically, DOUT is either directly monitored by the MCU, or run through an RC filter to convert it to an analog voltage that may be digitized and monitored by the host controller. In order to use the DOUT function, the nFLT2 pin must be reconfigured to select the DOUT functionality using the CFG1[NFLT2_DOUT_MUX] bit (CFG1 ). When the DOUT mode is selected, any warning or fault that was selected to report to nFLT2 now reports to nFLT1 automatically. Additionally, the frequency of DOUT is selectable between 4 options using the DOUTCFG[FREQ_DOUT] bits (DOUTCFG ). Select the channel to be monitored, using the DOUTCFG[DOUT_TO_AI*] bits (for the AI* inputs, DOUTCFG ) or the DOUTCFG[DOUT_TO_TJ] bit (DOUTCFG ) for the die junction temperature. If multiple channels are selected in the register, the duty cycle constantly changes as the ADC cycles through each channel read. It is recommended to only select one channel at a time for the DOUT function. In addition to this setup, the ADC must be enabled and setup correctly to read the desired channel to be monitored. See the ADC section for details on configuring the ADC. If a fault occurs that stops the driver output and ADC measurements, the DOUT output continues and represents the last good ADC reading.

These features allow the design of a robust system that protects against a variety of system related failure modes. When one of the monitored warnings or faults occurs, if unmasked, the nFLT1 output (for faults) or the nFLT2 output (for warnings) pulls low. All of the fault and warning bits have corresponding configuration bits that allow the user to mask the error or fault from showing up on the nFLT* output. The naming convention is straightforward. The mask bit is in a CFG* register and is named the same as the fault with the addition of an "_P". For example, a power FET short circuit current fault is indicated in the register bit STATUS3[SC_FAULT] (STATUS3)and the mask bit is CFG9[SC_FAULT_P] (CFG9). Throughout this document, the different warning/error bit locations are indicated in the functional description of the block where the warning/fault is monitored. When masked, the nFLT* indication does not occur, but the STATUS* bits still indicate the warning/fault condition. The device classifies error events into two categories, Warnings and Faults, and takes different device actions depending on the error classification. The Warning error class is used to report non-critical fault conditions. Warning errors are only reported with no action taken to affect the gate driver output or any other block. When a warning condition occurs, it is reported in on of the STATUS* registers and, if unmasked, the nFLT2 output is driven low. The nFLT2 indication for warning is cleared by a successful SPI read of the corresponding status register. Once cleared, warning indication is not repeated until the warning condition is removed and reapplied. For example, in an over temperature warning condition, after reading/clearing the bit the temperature must cool down to the normal operating range and then heat up again to the over temperature warning threshold for the error flag to be reasserted. The status bit always indicates the current state of the warning, and is not cleared until the error condition is removed. The Fault error class is used to report critical fault conditions. Fault errors have the ability to shut down the gate driver when they occur. When a fault condition occurs, it is reported in one of the STATUS* registers and, if unmasked, the nFLT1 output is driven low. Many faults have a corresponding configuration bit that enables the user to select the functional safe state of the driver when that fault occurs when the fault is not masked. These bits are in the CFG* registers, with bit names that start with "FS_STATE_". Throughout this document, the FS_STATE locations are indicated in the functional description of the block where the fault is monitored. The available options for the output state, depending on the fault, are PL (OUTL pulled low), PH (OUTH pulled high), or no action (gate driver output ignores the fault and continues normal operation). Faults are cleared when the condition is removed, and the CONTROL2[CLR_STAT_REG] bit (CONTROL2) is written. Fault indication reasserts as long as the fault condition exists and is unmasked. #GUID-2684F8A6-04AD-49B9-B2C2-ED345674CFC4/T4885753-84 provides an extensive list and details for the available faults and warnings.

These features allow the design of a robust system that protects against a variety of system related failure modes. When one of the monitored warnings or faults occurs, if unmasked, the nFLT1 output (for faults) or the nFLT2 output (for warnings) pulls low. All of the fault and warning bits have corresponding configuration bits that allow the user to mask the error or fault from showing up on the nFLT* output. The naming convention is straightforward. The mask bit is in a CFG* register and is named the same as the fault with the addition of an "_P". For example, a power FET short circuit current fault is indicated in the register bit STATUS3[SC_FAULT] (STATUS3)and the mask bit is CFG9[SC_FAULT_P] (CFG9). Throughout this document, the different warning/error bit locations are indicated in the functional description of the block where the warning/fault is monitored. When masked, the nFLT* indication does not occur, but the STATUS* bits still indicate the warning/fault condition. The device classifies error events into two categories, Warnings and Faults, and takes different device actions depending on the error classification. The Warning error class is used to report non-critical fault conditions. Warning errors are only reported with no action taken to affect the gate driver output or any other block. When a warning condition occurs, it is reported in on of the STATUS* registers and, if unmasked, the nFLT2 output is driven low. The nFLT2 indication for warning is cleared by a successful SPI read of the corresponding status register. Once cleared, warning indication is not repeated until the warning condition is removed and reapplied. For example, in an over temperature warning condition, after reading/clearing the bit the temperature must cool down to the normal operating range and then heat up again to the over temperature warning threshold for the error flag to be reasserted. The status bit always indicates the current state of the warning, and is not cleared until the error condition is removed. The Fault error class is used to report critical fault conditions. Fault errors have the ability to shut down the gate driver when they occur. When a fault condition occurs, it is reported in one of the STATUS* registers and, if unmasked, the nFLT1 output is driven low. Many faults have a corresponding configuration bit that enables the user to select the functional safe state of the driver when that fault occurs when the fault is not masked. These bits are in the CFG* registers, with bit names that start with "FS_STATE_". Throughout this document, the FS_STATE locations are indicated in the functional description of the block where the fault is monitored. The available options for the output state, depending on the fault, are PL (OUTL pulled low), PH (OUTH pulled high), or no action (gate driver output ignores the fault and continues normal operation). Faults are cleared when the condition is removed, and the CONTROL2[CLR_STAT_REG] bit (CONTROL2) is written. Fault indication reasserts as long as the fault condition exists and is unmasked. #GUID-2684F8A6-04AD-49B9-B2C2-ED345674CFC4/T4885753-84 provides an extensive list and details for the available faults and warnings.

DESAT detection function and function diagnostic Power transistor OCP, SCP, and TSD comparators and comparator diagnostics Power transistor high voltage clamping circuit detection and function diagnostics Active Miller clamp diagnostic Undervoltage Lockout (UVLO) and Overvoltage Lockout (OVLO) UVLO functions are implemented for all three gate driver power supplies VCC1, VCC2, and VEE2. The VCC1 UVLO/OVLO ensures a valid supply is connected for the required logic interface. The UVLO/OVLO for VCC2 and VEE2 ensures valid supplies based on the type of transistor used. The UVLO function prevents overheating damage to the IGBTs/MOSFETs from being under-driven. The OVLO functions are implemented to prevent gate oxide degradation (shortened lifetime) of the IGBTs/MOSFETs from an over-voltage supply at turned on. The device powers up when a valid VCC1 supply (VIT+(UVLO1) < VVCC1 < VIT+(OVLO1)) and non-UV VCC2 supply (VVCC2 > VIT+(UVLO2)) are connected. The driver outputs are high impedance until the valid supplies are connected and the internal supplies are in regulation. While the driver output is high impedance, the output to the gate of the external power switch is held low with a passive and active pulldown circuit. See the section for more details. Once valid supplies are connected and internal supplies are valid, the output state is determined by the Enable/Disable Driver command any fault conditions that exist. SPI communication is unavailable while VCC1 is lower than the UVLO1 threshold. The OVLO and UVLO functions are enabled/disabled using the following bits: CFG1[UV1_DIS] for VCC1 UVLO, CFG1[OV1_DIS] for VCC1 OVLO, CFG4[UV2_DIS] for VCC2 UVLO,CFG4[OV2_DIS] for VCC2 OVLO, and CFG4[UVOV3_EN] for both the OVLO and UVLO for VEE2. The UVLO and OVLO thresholds for VCC1, VCC2 and VEE2 are programmable in order to customize the driver for different types of power transistors. Use the CFG1[UVLO1_LEVEL] and CFG1[OVLO1_LEVEL] (for VCC1), CFG7[UVLO2TH] and CFG7[OVLO2TH] (for VCC2), and CFG7[UVLO3TH] and CFG7[IOVLO3TH] (for VEE2) bits to set the desired threshold. See CFG1 and CFG7. The fault status for the OVLO and UVLO function are located in STATUS2[UVLO1_FAULT] for VCC1 UVLO, STATUS2[OVLO1_FAULT] for VCC1 OVLO, STATUS3[UVLO2_FAULT] for VCC2 UVLO, STATUS3[OVLO2_FAULT] for VCC2 OVLO, STATUS3[UVLO3_FAULT] for VEE2 UVLO, and STATUS3[OVLO3_FAULT] for VEE2 OVLO. See STATUS2 and STATUS3 for additional details. The timing diagrams for the VCC1 and VCC2 UVLO and OVLO functions are shown in and , respectively. The VEE2 timing diagram is shown in . Illustration of UVLO and OVLO timing schemes of VCC1. Illustration of UVLO and OVLO timing schemes of VCC2 Illustration of UVLO and OVLO timing schemes of VEE2 Built-In Self Test (BIST) Analog Built-In Self Test (ABIST) The device automatically runs diagnostics on all of the under-voltage and over-voltage comparators monitoring VCC1, VCC2, VEE2, and internal regulators during the power up process. During the self-test of the comparators, an over-voltage and under-voltage condition is simulated. The actual monitored voltage rails remain unchanged and the disturbance is not observable. A failure in the ABIST for the primary side sets the STATUS2[BIST_PRI_FAULT] (STATUS2) and for the secondary side sets the SATUS4[BIST_SEC_FAULT] (STATUS4). Function BIST In addition to the automatic analog BIST, there are BIST diagnostics available for DESAT, the PWM signal (INP) check, STP, Gate Voltage Monitoring, SCP/OCP, PS_TSD, and VCECLP. Details for the functionality of each of these tests are provided in the CONTROL1 (CONTROL1) and CONTROL2 (CONTROL2) register bit descriptions. Clock Monitor The device integrates clock monitor functions to identify clock faults during operation. The Clock monitor detects internal oscillator failures: Oscillator clock stuck high or stuck low Clock frequency is out of range ±30% The clock monitor is enabled during a power-up event after the power-on reset is released. The clocks on the primary side and secondary side are monitored. In the event of a clock fault on the primary side, the STATUS4[CLK_MON_SEC_FAULT] bit (STATUS4 ) is set, the driver is forced to the state determined by the CFG11[FS_STATE_CLK_MON_SEC_FAULT] bit (CFG11) and, if unmasked, the nFLT1 output pulls low. In the event of a clock fault on the secondary side, the STATUS2[CLK_MON_PRI_FAULT] bit (STATUS2 ) is set, and, if unmasked, the nFLT1 output pulls low. The secondary side clock monitor has no effect on the gate driver output state. Clock Monitor Built-In Self Test The clock monitor circuit integrates a diagnostic that checks the integrity of the monitoring circuit. The diagnostic is run automatically during the startup process. Additionally, a simulated clock monitor fault is generated by writing the CONTROL1[CLK_MON_CHK_PRI] bit () for the primary side and the CONTROL2[CLK_MON_CHK_SEC] bit () for the secondary side. When enabled, the enabled diagnostics emulates clock failure that causes a clock monitor fault. During this self-test, the actual oscillator frequency is not changed. CLAMP, OUTH, and OUTL Clamping Circuits Integrated diodes prevent the OUTH and CLAMP outputs from exceeding VCC2. The short circuit clamping function clamps the voltages at the driver output (OUTH) and active Miller clamp (CLAMP) outputs to be slightly higher than VCC2 during power switch short circuit conditions. The clamped gate voltage limits the short circuit current and prevents the IGBT/MOSFET gate from overvoltage breakdown or degradation. The internal diodes conduct up to 500 mA current for a duration of 10us, and a continuous current of 20mA. Use external Schottky diodes to improve current conduction capability, if needed. While VCC2 is unpowered, the gate of the external power switch is held off with an active pulldown circuit. If the OUTL suddenly rises due to ramping VCC2 during power up, the active pulldown function pulls the IGBT/MOSFET gate to the low state and maintains the OUTL voltage below VOUTSD. See for a drawing of the clamping circuits. CLAMP, OUTH, and OUTL Clamping Circuits Active Miller Clamp The Active Miller clamp function (CLAMP output) is used to prevent the power transistor from false turn-on due Miller capacitance induced current. The active Miller clamp adds a low impedance path between power transistor gate terminal and VEE2 to pull the gate of the external FET hard to VEE2, bypassing any external gate resistors. The Miller clamp engages when the OUTH voltage falls below the VCLPTH, which is selected using the CFG5[MCLPTH] bits (CFG5). Additionally, the Miller clamp is enabled/disabled using the CFG4[MCLP_DIS] bit (CFG4). The status of the Miller clamp is available in the STATUS3[MCLP_STATE] bit (STATUS3). If additional pulldown strength is required, the CLAMP output is configured to drive an external Miller clamp FET. Use the CFG4[MCLP_CFG] bit to select between the internal and external Miller clamp (CFG4). This option can be configured through the register. The implementation block diagram and timing scheme are shown in and respectively. Block diagram of implementation of internal Miller clamp function. Block diagram of implementation of external Miller clamp function. Timing scheme of implementation of Miller clamp function. DESAT based Short Circuit Protection (DESAT) DESAT protection prevents the power transistor from damage in case of short circuit faults. The DESAT input monitors the VCEsat (IGBT)/VDSon (MOSFET) through an external resistor and diode network (R1, C1, D1 and D2 in ). The D1 diode protects the driver IC from high voltage when the power transistor is OFF. The resistor, R1, limits the negative voltage applied on the DESAT input during switching transitions. While the power FET is ON, an internal current source, ICHG, forward biases the DESAT diode and dumps into the collector/drain of the external power switch. Under normal conditions, the VCEsat/VDSon is less than a few volts, however, during short circuit faults the VCEsat/VDSon may rise up to the DC bus voltage when the power transistor operates in the linear region. In this situation, the D1 diode is reverse biased, so the internal current source charges the blanking capacitor (C1) Once the voltage on the DESAT input charges up to the selected threshold (VDESATth),the driver output is pulled into the safe state defined by the CFG10[FS_STATE_DESAT_SCP] bit (CFG10), the fault is indicated in the STATUS3[DESAT_FAULT] (STATUS3), and, if unmasked, the NFLT1 output pulls low. The turn-off of the driver output during a DESAT fault is selectable between normal, soft turn-off (STO), or two-level turnoff (2LTO) dictated by the CFG5[2LTOFF_STO_EN] bits (CFG5). See the and for additional details on STO and 2LTO, respectively. The blanking capacitor is fully discharged at the falling edge of the PWM signal using the internal discharge current (IDCHG). In addition to the blanking time, DESAT is deglitched to prevent false triggering during transitions. The deglitch is selectable using the CFG4[DESAT_DEGLITCH] bit (CFG4). The DESAT threshold is selectable using the CFG5[DESATTH] bits (CFG5), and the DESAT charging current (ICHG) is selectable, using the CFG5[DESAT_CHG_CURR] bits (CFG5), to control the blanking time (tDS_BLK). The discharge current is enabled/disabled using the CFG5[DESAT_DCHG_EN] bit (CFG5). The DESAT protection function is enabled or disabled using the CFG4[DESAT_EN] bit (CFG4). The implementation diagram and timing schemes of DESAT based short circuit protection are presented in and respectively. See the section for details on selecting the R1, C1, and D1 values. Block diagram of implementation of DESAT protection function. Timing scheme of implementation of DESAT protection function (safe state is LOW). Shunt Resistor based Overcurrent Protection (OCP) and Short Circuit Protection (SCP) The device designates three AI* inputs (AI2, AI4, AI6) to support shunt resistor based OCP and SCP in order to support up to three power transistors in parallel. Shunt resistor based OCP/SCP protections are intended for power transistors with integrated current sense FETs. The mirrored power transistor currents is fed into a resistor, and the voltage is monitored at the AI* input. Once the voltage at the AI* input exceeds the threshold programmed using CFG6[OCTH] (for OCP, CFG6) or CFG6[SCTH] (for SCP, CFG6), the fault is indicated in the STATUS3[OC_FAULT] (for OCP, STATUS3) or the STATUS3[SC_FAULT] (for SCP, STATUS3), and if unmasked, nFLT1x is pulled low and the driver output goes to the state defined by CFG10[FS_STATE_OCP] (for OCP, CFG10) or CFG10[FS_STATE_SCP] (for SCP, CFG10). The turn-off of the driver output during a OCP or SCP fault is selectable between normal, soft turn-off (STO), or two-level turnoff (2LTO) dictated by the CFG5[2LTOFF_STO_EN] bits (CFG5). See the Soft Turn-off (STO) and Two-Level Turn-Off for additional details on STO and 2LTO, respectively. A blanking time is used for both OCP and SCP to prevent unwanted false protection triggering during transitions and is selectable in CFG6[OC_BLK] (for OCP, CFG6)) or CFG6[SC_BLK] (for SCP, CFG6)). Once the blanking time expires, any SCP/OCP fault must exist for the deglitch time before the fault is registered. Enable/disable which AI* inputs are to be used for SCP/OCP using the DOUTCFG[AI*OCSC_EN] bits (DOUTCFG). The OCP and SCP functions are enabled for the selected AI* inputs using the CFG4[OCP_DIS] (for OCP, CFG4) and CFG4[SCP_DIS] (for SCP, CFG4) bits. Please note that if AI6 is to be used for OCP/SCP, the CFG8[AI_ASC_MUX] bit (CFG8) must be configured as an ADC input. The implementation diagram and timing schemes for the shunt resistor based OCP and SCP are presented in Block diagram of implementation of shunt resistor based OCP and SCP functions and Timing scheme of implementation of shunt resistor based OCP function (safe state is LOW) respectively. Block diagram of implementation of shunt resistor based OCP and SCP functions. Timing scheme of implementation of shunt resistor based OCP function (safe state is LOW) Current sources are available for AI2, AI4, and AI6 as open pin diagnosis tools. Enable the current sources using the CFG3[ITO2_EN] bit (CFG3). When enabled, the AI2, AI4, AI6 inputs are pulled high if left unconnected. Temperature Monitoring and Protection for the Power Transistors The device designates three AI* inputs (AI1, AI3, AI5) to support NTC diode sensing for up to three power transistors in parallel. The temperature protection is intended for power transistors with integrated temperature sensing diodes. The AI* input provides a zero-TC current that biases the integrated diode, and the voltage is monitored at the AI* input. The bias current is controlled using CFG3[ITO1_EN] (CFG3) as a master enable, and then using CFG3[AI_IZTC_SEL] (CFG3) to select which AI* output is to receive the bias current. Once the voltage at the AI* input falls below the threshold programmed using CFG6[TSD_PS] (CFG6), the fault is indicated in the STATUS3[PS_TSD_FAULT] (STATUS3), and if unmasked, nFLT1 is pulled low and the driver output goes to the state defined by CFG10[FS_STATE_PS_TSD] (CFG10). The turn-off of the driver output during an PS_TSD fault is selectable between normal, soft turn-off (STO), or two-level turnoff (2LTO) dictated by the CFG5[2LTOFF_STO_EN] bits. See the and for additional details on STO and 2LTO, respectively. Any PS_TSD fault must exist for the deglitch time programmed using the CFG4[PS_TSD_DEGLITCH] bits (CFG4) before the fault is registered. Enable/disable which AI* inputs are to be used for PS_TSD using the DOUTCFG[AI*PS_TSD_EN] bits (DOUTCFG). The temperature monitoring function is enabled for the selected AI* inputs using the CFG4[PS_PS_TEMP_EN] bit (CFG4). Please note that if AI5 is to be used for power switch temperature monitoring, the CFG8[AI_ASC_MUX] bit (CFG8) must be configured as an ADC input. The implementation diagram and timing schemes of PS_TSD are presented in and respectively. Block diagram of implementation of PS temperature monitoring function. Timing scheme of implementation of PS_TSD function. Active High Voltage Clamping (VCECLP) The active high voltage clamping feature protects power transistors from over-voltage damage during switching transitions, while reducing the power dissipated in the external TVS clamp diodes protecting the power FET. During turn-off, the VCECLP input is monitored. Once the VCE of the FET increases to turn on the external TVS diode, the RC network on the VCECLP input is charged up. Once the VCECLP input reaches the clamp threshold (VCECLPTH), OUTL drive strength changes to the ISTO setting in order to slow down the turn off and reduce the overshoot. The high voltage clamping remains active for a predefined time tVCECLP_HLD. The OV condition is reported in STATUS3[VCEOV_FAULT] (STATUS3). The implementation and timing diagrams for the active high voltage clamping are presented in and , respectively. The VCECLP feature is enabled/disabled using the CFG4[VCECLP_EN] bit (CFG4). Block diagram of implementation of active high voltage clamping function. Timing scheme of implementation of active high voltage clamping function. Two-Level Turn-Off The two-level turn-off (2LTOFF) function limits the transistor current during shutoff during certain fault conditions. The 2LTOFF function is enabled for PS_OC, PS_SC, PS_TSD, and/or DESAT faults using the CF5[2LTOFF_STO_EN] bits (CFG5). When 2LTOFF is triggered, the gate of the power transistor is controlled to operate the transistor in the linear region where the channel current is controlled by the voltage level on the gate terminal. The power transistor current is reduced by controlling the gate voltage to a intermediate voltage, or plateau voltage, (V2LOFF) for t2LOFF, and then ramping the gate down to turn the power transistor off. While 2LTOFF is active, OUTL sinks current to discharge the gate capacitor of the power switch to the plateau voltage. The gate discharge current is programmable using the CFG8[GD_2LOFF_CURR] bits (CFG8). The plateau voltage level and duration are configured using the CFG8[GD_2LOFF_VOLT] and CFG8[GD_2LOFF_TIME] bits (CFG8), respectively. After holding the plateau voltage for the programmed time, the gate is discharged fully using the soft turn-off current or pulled low as normal with the OUTL driver. Enable the soft turn off current using the CFG8[GD_2LOFF_STO_EN] bit (CFG8). The implementation diagram and timing scheme are presented in and , respectively. Block diagram of implementation of two-level turn-off function Timing scheme of implementation of two-level turn-off function Soft Turn-Off (STO) The soft turn-off (STO) function prevents power transistors from OV damage because of parasitic loop inductance induced voltage spikes on VCE. The STO slows down the turn-off process that to limit the di/dt rate, and thus limits the loop inductance induced voltage spikes. During STO, the OUTL drive strength is reduced to the threshold programmed using the CFG5[STO_CURR] bits (CFG5). The STO function is enabled for PS_OC, PS_SC, PS_TSD, and/or DESAT faults using the CF5[2LTOFF_STO_EN] bits (CFG5). Thermal Shutdown (TSD) and Temperature Warning (TWN) of Driver IC C 20210503 Updated secondary side TSD behavior to clarify the functions operation. yes Gate driver temperature monitoring prevents driver IC from damage during overheating conditions. Both the primary and secondary sides of the driver utilize thermal warning and shutdown comparators to help prevent damage due to high temperatures. When a thermal warning is detected on the primary side, the STATUS1[GD_TWN_PRI_FAULT] (STATUS1) is set and, if unmasked, the nFLT2 output is pulled low. If over temperature event is detected on the primary side, the device transitions to the RESET state where the driver output is held low. Once the device cools, the device must be reconfigured as described in the Programming section before enabling the driver output. When a thermal warning is detected on the secondary side, the STATUS4[GD_TWN_SEC_FAULT](STATUS4) is set and, if unmasked, the nFLT2 output is pulled low. When a thermal shutdown is detected on the secondary side, the driver is disabled, , the STATUS4[GD_TSD_SEC_FAULT] (STATUS4), is set and, if unmasked, the nFLT1 output is pulled low. The status register flag for TSD may not be set depending on the timing of the thermal event, however the nFLT1 indicator will be pulled low. In the case of the secondary thermal shutdown event, the clock monitor and inter-die communication faults will likely be indicated. This is expected behavior due to the secondary side being shutdown and not communicating to the primary side. Once the driver cools and communication is reestablished, the device must be reconfigured as described in the Programming section before turning on the driver output. A blanking time is inserted to prevent unwanted false triggering of the protection circuits. Timing scheme of implementation of driver IC TSD function. Active Short Circuit Support (ASC) C 20210503 Added information about gate monitoring during secondary side ASC operation. yes The active short circuit (ASC) function allows the system to force the state of the power transistor regardless of the PWM input. For cases where the main MCU is not available due to fault or otherwise, a secondary control circuit drives the ASC_EN input high to force the output of the device to the state defined by the ASC input. For the primary side, two dedicated inputs are available for the ASC control. The ASC control is also available on the secondary side using the AI5 and AI6 inputs. To configure the device with the secondary ASC function, the CFG8[AI_ASC_MUX] bit (CFG8) must be configured in ASC mode. In this configuration, AI5 is ASC_EN and AI6 is the ASC input. The operation is identical to what is described for the primary side. Please note that if AI5/AI6 are to be used for the ASC function they are unavailable for OCP/SCP and PS temperature monitoring. When using the secondary side ASC, it is possible that the GM_FAULT will be set (when enabled) if the IN+ state is different than the ASC state. There will be no fault action taken, but the STATUS3[GM_FAULT] will be set. The implementation flow of ASC function is presented in . This implementation assumes both primary and secondary ASC are used. The secondary ASC covers the failure mode where VCC1 power is down. The primary and secondary ASC functions can be used independently. If both ASC functions are enabled, the secondary ASC has highest priority. The ASC functions are available in all operation states, assuming there is a valid power supply (VCC1 and VCC2 for ASC/ASC_EN or VCC2 for AI5/AI6). ASC implementation Flowchart ASC implementation logic. Shoot-Through Protection (STP) The shoot through protection function (STP) provides an additional layer of protection from shoot through conditions due to incorrect PWM commands from MCU. The output of the driver uses IN+ and the complementary PWM signal provided to the IN- input to set the output state of the driver. Both the IN+ and IN- inputs are deglitched by tGLITCH, which is programmable using CFG1[IO_DEGLITCH] bits (CFG1). There are two available version of STP, IN+/IN- safety interlock and automatic dead-time. The safety interlock function is enabled by setting the CFG1[TDEAD] bits (CFG1) to 0b000000 (tDEAD = 0). When using the safety interlock STP, if IN+ and IN- are both high at the same time, a shoot-through condition (STP fault) is detected. During an STP fault, the STATUS2[STP_FAULT] bit (STATUS2 ) is set, and, if unmasked, the nFLT1 output pulls low. The output of the driver is forced to the state defined by CFG3[FS_STATE_STP_FAULT] (CFG3 ). When the tDEAD is non-zero (CFG1[TDEAD] ≠ 0b000000, dead time is added to the falling edge of IN- by the device. In these cases, when IN+ goes high, the device waits until the deglitched falling edge of IN-, then OUTH pulls high tDEAD after the deglitched IN- is low. The implementation diagram and timing schemes are presented in and respectively. Block diagram of implementation of STP function. Timing scheme of implementation of STP function. Gate Voltage Monitoring and Status Feedback The integrity of the PWM channel is monitored end to end using two checks. The first check monitors the communication across the isolation channel. The received state on the secondary side is communicated back o the primary side to ensure the two match. If there is a mismatch between the IN+ state and the received IN+ state, the STATUS1[PWM_COMP_CHK_FAULT] bit (STATUS1) is set, if unmasked, nFLT1 pulls low, and the driver output is forced ot the state defined by CFG3[FS_STATE_PWM_CHK] (CFG3). The second check monitors the actual gate voltage of the power transistor to ensure the gate is in the correct state. The monitored gate voltage is first converted to logic state and indicated in the STATUS3[GM_STATE] bit (STATUS3). The converted gate voltage logic state is then compared with the input PWM (IN+) signal. The mismatch of the two signals causes a gate voltage monitor fault condition where the STATUS3[GM_FAULT] bit (STATUS3 ) is set, the driver output is forced to the state defined by CFG10[FS_STATE_GM] (CFG10 ), and, if unmasked, nFLT1 pulls low. Blanking time relative to the driver outputs is used to prevent false reporting of the gate voltage monitor error during driver transitions. During 2LTOFF transitions, the blanking time starts after the 2LTOFF plateau timer expires in order to prevent false GM faults during the transition. Alternatively, the GM fault may be disabled during STO and 2LTOFF using the CFG5[GM_STO2LTO_DIS] bit (CFG5). The blanking time is adjustable using the CFG4[GM_BLK] bits (CFG4). Additionally, the gate monitoring function may be disabled entirely using the CFG4[GM_EN] bit (CFG4). The implementation block diagram and timing schemes are presented in and . Block diagram of implementation of gate voltage monitor function. Timing scheme of implementation of gate voltage monitor function. VGTH Monitor C 20210503 Corrected equation. yes The VGTH Monitor function is used to measure the gate threshold voltage of the power transistor during power up. When enabled using the CONTROL2[VGTH_MEAS] bit (CONTROL2), the switch between DESAT and OUTH is turned on. A constant current source charges the gate capacitance of the power transistor and the gate voltage ramps up gradually. Once the channel starts to conduct, the gate voltage is naturally held at the threshold voltage level as the power transistor in a diode configuration. After the blanking time, tdVGTHM, the integrated ADC samples the gate voltage, and reports the measurement in register ADCDATA8. The measurement is actually a divided down version (divided by 8) of the gate voltage. The actual threshold voltage is calculated as: VGTH = VADCDATA8 × 8 This measurement is then used by the MCU to judge the health of the power transistor. VGTH monitoring circuit current flow while charging the gate capacitance VGTH monitoring circuit current flow while the power transistor is in diode configuration Cyclic Redundancy Check (CRC) the device uses a cyclic redundancy check (CRC) to ensure data integrity for the configuration of the device while the driver output is active, the SPI communications (both transmitted and received), and the internal non-volatile memory that store the trim information that ensures the performance of the device. The CRC represents the remainder of a process analogous to polynomial long division, where the protected data is divided by the polynomial. The device uses the CRC8 polynomial X8 + X2 + X + 1 with a 0xFF initialization (to catch leading 0 errors) for its calculations. Calculating CRC The calculation process begins by initializing the command frame by XORing it with the current CRC (0xFF for the very first command frame). Next, the XOR'd value is divided by the polynomial. The result is used as the CRC for the next frame. Repeat the process until all of the frames are run through the calculation. Note that the CRC is updated internal with every 16-bits, so the actual read/write command byte must be included in the calculation. See for an example calculation. Configuration Data CRC C 20210503 Corrected CONTROL2 bit name in list yes When the device transitions to the ACTIVE state, the contents of configuration and control registers are protected by CRC engine. The configuration CRC is enabled using the CFG8[CRC_DIS] bit (CFG8). The registers protected by the CRC include: CFG1 - CFG11 ADCCFG DOUTCFG GD_ADDRESS[GD_ADDR] (no MSB) SPITEST CONTROL1 CONTROL2, excluding the MSB (CONTROL2[CLR_STAT_REG]) The CRC fault detection is performed every tCRCCFG (typically 2 ms). If the calculated CRC8 checksum for the configuration registers does not match the CRC8 checksum calculated upon entering the Active state, the STATUS2[CFG_CRC_PRI_FAULT] (for a primary side CRC fail, STATUS2) or the STATUS4[CFG_CRC_SEC_FAULT] (for a secondary side CRC fail, STATUS4) bit is set and, if unmasked, the nFLT1 output goes low. Additionally, for the secondary side CRC failure, the driver output is forced to the state defined by CFG11[FS_STATE_CFG_CRC_SEC_FAULT] (CFG11). Diagnostics for the CRC check are available. Use the CONTROL1[CFG_CRC_CHK_PRI] (CONTROL1) to induce a CRC error on the primary side. CONTROL2[CFG_CRC_CHK_SEC] (CONTROL2) to induce a CRC error on the secondary side. Writing to any of the "RESERVED" bits in the configuration registers also induces a CRC fault. Configuration Data CRC Check Timing SPI Transfer Write/Read CRC The CRC checks for SPI transfer are continuously updated as SPI traffic is received/ sent. The CRC is updated with every 16-bits that are received. An example of calculating the SPI CRC for a sent command is given in . In this set of commands, we are updating the configuration for CFG1 and then doing a CRC comparison on that command. Example of CRC Calculation While Updating CFG1 Command Purpose CRC Before CRC_After 0xFC00 Change the SPI address pointer to CFG1 register 0xFF (Initialized) 0x3F 0xFA58 Update the high byte with 0x58 configuration 0x3F 0x23 0xFB2A Update the low byte with 0x2A configuration 0x23 0xC4 0xFC13 Change the SPI address point to CRCDATA register 0xC4 0x28 0xFA30 Update the CRC_TX bits with the calculated CRC 0x28 0x30 (written to the CRC_TX bits) Calculating CRC for a Set of Commands SDI CRC Check The SDI CRC checksum data is continuously calculated as SPI data frames are received. Once the MCU writes to the to CRCDATA[CRC_TX] bits (CRCDATA). The write to these bits triggers a comparison of the data in the CRC_TX bits with the internally calculated CRC. Once the comparison is complete, the CRC calculation logic is reset (reset value = 0xFF). When there is a mismatch between CRC_TX data and CRC calculated internally, the STATUS2[SPI_FAULT] bit (STATUS2) is and, if unmasked, the nFLT1 output pulls low. Additionally, the output of the driver is forced to the state programmed in CFG3[FS_STATE_SPI_FAULT] (CFG3). SDO CRC Check The SDO CRC checksum is continuously calculated as data is clocked out of SDO. The resulting CRC is stored in the CRCDATA[CRC_RX] bits. The bits are updated whenever nCS transitions from low to high. The CRC calculation logic is reset (reset value = 0xFF) when the CRC_RX bits are read or when the CONTROL1[CLR_SPI_CRC] bit is written. Note that the CRC_RX bits are reset immediately with the read, and the next CRC_RX value begins its calculation while clocking out of the CRC_RX bits. This means the received CRC_RX must be included in the next CRC calculation (i.e. the received CRC_RX is the first byte to be xor'd with the 0xFF reset value). TRIM CRC Check After each power up, the device performs a TRIM CRC check on the internal non-volatile memory on both the primary and secondary sides. If the calculated CRC8 checksum does not match the CRC8 checksum stored in the internal TRIM memory, the STATUS2[TRIM_CRC_PRI_FAULT] (for a primary side CRC fail, STATUS2) or the STATUS4[TRIM_CRC_SEC_FAULT] (for a secondary side CRC fail, STATUS4) bit is set and, if unmasked, the nFLT1 output goes low. Additionally for the secondary side CRC failure, the driver output is forced to the state defined by CFG11[FS_STATE_TRIM_CRC_SEC_FAULT] (CFG11).

The VCC1 UVLO/OVLO ensures a valid supply is connected for the required logic interface. The UVLO/OVLO for VCC2 and VEE2 ensures valid supplies based on the type of transistor used. The UVLO function prevents overheating damage to the IGBTs/MOSFETs from being under-driven. The OVLO functions are implemented to prevent gate oxide degradation (shortened lifetime) of the IGBTs/MOSFETs from an over-voltage supply at turned on. The device powers up when a valid VCC1 supply (VIT+(UVLO1) < VVCC1 < VIT+(OVLO1)) and non-UV VCC2 supply (VVCC2 > VIT+(UVLO2)) are connected. The driver outputs are high impedance until the valid supplies are connected and the internal supplies are in regulation. While the driver output is high impedance, the output to the gate of the external power switch is held low with a passive and active pulldown circuit. See the section for more details. Once valid supplies are connected and internal supplies are valid, the output state is determined by the Enable/Disable Driver command any fault conditions that exist. SPI communication is unavailable while VCC1 is lower than the UVLO1 threshold. The OVLO and UVLO functions are enabled/disabled using the following bits: CFG1[UV1_DIS] for VCC1 UVLO, CFG1[OV1_DIS] for VCC1 OVLO, CFG4[UV2_DIS] for VCC2 UVLO,CFG4[OV2_DIS] for VCC2 OVLO, and CFG4[UVOV3_EN] for both the OVLO and UVLO for VEE2. The UVLO and OVLO thresholds for VCC1, VCC2 and VEE2 are programmable in order to customize the driver for different types of power transistors. Use the CFG1[UVLO1_LEVEL] and CFG1[OVLO1_LEVEL] (for VCC1), CFG7[UVLO2TH] and CFG7[OVLO2TH] (for VCC2), and CFG7[UVLO3TH] and CFG7[IOVLO3TH] (for VEE2) bits to set the desired threshold. See CFG1 and CFG7.

Illustration of UVLO and OVLO timing schemes of VCC2 Illustration of UVLO and OVLO timing schemes of VEE2 Built-In Self Test (BIST) Analog Built-In Self Test (ABIST) The device automatically runs diagnostics on all of the under-voltage and over-voltage comparators monitoring VCC1, VCC2, VEE2, and internal regulators during the power up process. During the self-test of the comparators, an over-voltage and under-voltage condition is simulated. The actual monitored voltage rails remain unchanged and the disturbance is not observable. A failure in the ABIST for the primary side sets the STATUS2[BIST_PRI_FAULT] (STATUS2) and for the secondary side sets the SATUS4[BIST_SEC_FAULT] (STATUS4). Function BIST In addition to the automatic analog BIST, there are BIST diagnostics available for DESAT, the PWM signal (INP) check, STP, Gate Voltage Monitoring, SCP/OCP, PS_TSD, and VCECLP. Details for the functionality of each of these tests are provided in the CONTROL1 (CONTROL1) and CONTROL2 (CONTROL2) register bit descriptions. Clock Monitor The device integrates clock monitor functions to identify clock faults during operation. The Clock monitor detects internal oscillator failures: Oscillator clock stuck high or stuck low Clock frequency is out of range ±30% The clock monitor is enabled during a power-up event after the power-on reset is released. The clocks on the primary side and secondary side are monitored. In the event of a clock fault on the primary side, the STATUS4[CLK_MON_SEC_FAULT] bit (STATUS4 ) is set, the driver is forced to the state determined by the CFG11[FS_STATE_CLK_MON_SEC_FAULT] bit (CFG11) and, if unmasked, the nFLT1 output pulls low. In the event of a clock fault on the secondary side, the STATUS2[CLK_MON_PRI_FAULT] bit (STATUS2 ) is set, and, if unmasked, the nFLT1 output pulls low. The secondary side clock monitor has no effect on the gate driver output state. Clock Monitor Built-In Self Test The clock monitor circuit integrates a diagnostic that checks the integrity of the monitoring circuit. The diagnostic is run automatically during the startup process. Additionally, a simulated clock monitor fault is generated by writing the CONTROL1[CLK_MON_CHK_PRI] bit () for the primary side and the CONTROL2[CLK_MON_CHK_SEC] bit () for the secondary side. When enabled, the enabled diagnostics emulates clock failure that causes a clock monitor fault. During this self-test, the actual oscillator frequency is not changed.

CLAMP, OUTH, and OUTL Clamping Circuits Integrated diodes prevent the OUTH and CLAMP outputs from exceeding VCC2. The short circuit clamping function clamps the voltages at the driver output (OUTH) and active Miller clamp (CLAMP) outputs to be slightly higher than VCC2 during power switch short circuit conditions. The clamped gate voltage limits the short circuit current and prevents the IGBT/MOSFET gate from overvoltage breakdown or degradation. The internal diodes conduct up to 500 mA current for a duration of 10us, and a continuous current of 20mA. Use external Schottky diodes to improve current conduction capability, if needed. While VCC2 is unpowered, the gate of the external power switch is held off with an active pulldown circuit. If the OUTL suddenly rises due to ramping VCC2 during power up, the active pulldown function pulls the IGBT/MOSFET gate to the low state and maintains the OUTL voltage below VOUTSD.

DESAT based Short Circuit Protection (DESAT) DESAT protection prevents the power transistor from damage in case of short circuit faults. The DESAT input monitors the VCEsat (IGBT)/VDSon (MOSFET) through an external resistor and diode network (R1, C1, D1 and D2 in ). The D1 diode protects the driver IC from high voltage when the power transistor is OFF. The resistor, R1, limits the negative voltage applied on the DESAT input during switching transitions. While the power FET is ON, an internal current source, ICHG, forward biases the DESAT diode and dumps into the collector/drain of the external power switch. Under normal conditions, the VCEsat/VDSon is less than a few volts, however, during short circuit faults the VCEsat/VDSon may rise up to the DC bus voltage when the power transistor operates in the linear region. In this situation, the D1 diode is reverse biased, so the internal current source charges the blanking capacitor (C1) Once the voltage on the DESAT input charges up to the selected threshold (VDESATth),the driver output is pulled into the safe state defined by the CFG10[FS_STATE_DESAT_SCP] bit (CFG10), the fault is indicated in the STATUS3[DESAT_FAULT] (STATUS3), and, if unmasked, the NFLT1 output pulls low. The turn-off of the driver output during a DESAT fault is selectable between normal, soft turn-off (STO), or two-level turnoff (2LTO) dictated by the CFG5[2LTOFF_STO_EN] bits (CFG5). See the and for additional details on STO and 2LTO, respectively. The blanking capacitor is fully discharged at the falling edge of the PWM signal using the internal discharge current (IDCHG). In addition to the blanking time, DESAT is deglitched to prevent false triggering during transitions. The deglitch is selectable using the CFG4[DESAT_DEGLITCH] bit (CFG4). The DESAT threshold is selectable using the CFG5[DESATTH] bits (CFG5), and the DESAT charging current (ICHG) is selectable, using the CFG5[DESAT_CHG_CURR] bits (CFG5), to control the blanking time (tDS_BLK).

Shunt Resistor based Overcurrent Protection (OCP) and Short Circuit Protection (SCP) The device designates three AI* inputs (AI2, AI4, AI6) to support shunt resistor based OCP and SCP in order to support up to three power transistors in parallel. Shunt resistor based OCP/SCP protections are intended for power transistors with integrated current sense FETs. The mirrored power transistor currents is fed into a resistor, and the voltage is monitored at the AI* input. Once the voltage at the AI* input exceeds the threshold programmed using CFG6[OCTH] (for OCP, CFG6) or CFG6[SCTH] (for SCP, CFG6), the fault is indicated in the STATUS3[OC_FAULT] (for OCP, STATUS3) or the STATUS3[SC_FAULT] (for SCP, STATUS3), and if unmasked, nFLT1x is pulled low and the driver output goes to the state defined by CFG10[FS_STATE_OCP] (for OCP, CFG10) or CFG10[FS_STATE_SCP] (for SCP, CFG10). The turn-off of the driver output during a OCP or SCP fault is selectable between normal, soft turn-off (STO), or two-level turnoff (2LTO) dictated by the CFG5[2LTOFF_STO_EN] bits (CFG5). See the Soft Turn-off (STO) and Two-Level Turn-Off for additional details on STO and 2LTO, respectively. A blanking time is used for both OCP and SCP to prevent unwanted false protection triggering during transitions and is selectable in CFG6[OC_BLK] (for OCP, CFG6)) or CFG6[SC_BLK] (for SCP, CFG6)).

Both the primary and secondary sides of the driver utilize thermal warning and shutdown comparators to help prevent damage due to high temperatures. When a thermal warning is detected on the primary side, the STATUS1[GD_TWN_PRI_FAULT] (STATUS1) is set and, if unmasked, the nFLT2 output is pulled low. If over temperature event is detected on the primary side, the device transitions to the RESET state where the driver output is held low. Once the device cools, the device must be reconfigured as described in the Programming section before enabling the driver output. When a thermal warning is detected on the secondary side, the STATUS4[GD_TWN_SEC_FAULT](STATUS4) is set and, if unmasked, the nFLT2 output is pulled low. When a thermal shutdown is detected on the secondary side, the driver is disabled, , the STATUS4[GD_TSD_SEC_FAULT] (STATUS4), is set and, if unmasked, the nFLT1 output is pulled low. The status register flag for TSD may not be set depending on the timing of the thermal event, however the nFLT1 indicator will be pulled low. In the case of the secondary thermal shutdown event, the clock monitor and inter-die communication faults will likely be indicated. This is expected behavior due to the secondary side being shutdown and not communicating to the primary side.

Active Short Circuit Support (ASC) C 20210503 Added information about gate monitoring during secondary side ASC operation. yes The active short circuit (ASC) function allows the system to force the state of the power transistor regardless of the PWM input. For cases where the main MCU is not available due to fault or otherwise, a secondary control circuit drives the ASC_EN input high to force the output of the device to the state defined by the ASC input. For the primary side, two dedicated inputs are available for the ASC control. The ASC control is also available on the secondary side using the AI5 and AI6 inputs. To configure the device with the secondary ASC function, the CFG8[AI_ASC_MUX] bit (CFG8) must be configured in ASC mode. In this configuration, AI5 is ASC_EN and AI6 is the ASC input. The operation is identical to what is described for the primary side. Please note that if AI5/AI6 are to be used for the ASC function they are unavailable for OCP/SCP and PS temperature monitoring. When using the secondary side ASC, it is possible that the GM_FAULT will be set (when enabled) if the IN+ state is different than the ASC state.

Shoot-Through Protection (STP) The shoot through protection function (STP) provides an additional layer of protection from shoot through conditions due to incorrect PWM commands from MCU. The output of the driver uses IN+ and the complementary PWM signal provided to the IN- input to set the output state of the driver. Both the IN+ and IN- inputs are deglitched by tGLITCH, which is programmable using CFG1[IO_DEGLITCH] bits (CFG1). There are two available version of STP, IN+/IN- safety interlock and automatic dead-time. The safety interlock function is enabled by setting the CFG1[TDEAD] bits (CFG1) to 0b000000 (tDEAD = 0). When using the safety interlock STP, if IN+ and IN- are both high at the same time, a shoot-through condition (STP fault) is detected. During an STP fault, the STATUS2[STP_FAULT] bit (STATUS2 ) is set, and, if unmasked, the nFLT1 output pulls low.

Gate Voltage Monitoring and Status Feedback The integrity of the PWM channel is monitored end to end using two checks. The first check monitors the communication across the isolation channel. The received state on the secondary side is communicated back o the primary side to ensure the two match. If there is a mismatch between the IN+ state and the received IN+ state, the STATUS1[PWM_COMP_CHK_FAULT] bit (STATUS1) is set, if unmasked, nFLT1 pulls low, and the driver output is forced ot the state defined by CFG3[FS_STATE_PWM_CHK] (CFG3). The second check monitors the actual gate voltage of the power transistor to ensure the gate is in the correct state. The monitored gate voltage is first converted to logic state and indicated in the STATUS3[GM_STATE] bit (STATUS3). The converted gate voltage logic state is then compared with the input PWM (IN+) signal.

Blanking time relative to the driver outputs is used to prevent false reporting of the gate voltage monitor error during driver transitions. During 2LTOFF transitions, the blanking time starts after the 2LTOFF plateau timer expires in order to prevent false GM faults during the transition. Alternatively, the GM fault may be disabled during STO and 2LTOFF using the CFG5[GM_STO2LTO_DIS] bit (CFG5). The blanking time is adjustable using the CFG4[GM_BLK] bits (CFG4).

The current state of the device is read in the STATUS1[OPM] bits (STATUS1). Note that these bits are only readable in the Configuration 2 and Active states. State 1: RESET State 2: Configuration 1 State 3: Configuration 2 State 4: Active Operation mode diagram during normal operation State 1: RESET When a valid power supply is first applied to VCC1, the device enters the RESET state. In the RESET state, the device does not respond to commands from MCU, the driver outputs (OUTL and OUTH) are both high impedance, the registers are reset to the default values, and all of the built In Self Tests (BIST) run. The nFLTx outputs are held low until a power source is connected to VCC2, all of the automatic BISTs complete, and the device transitions to the Configuration 1 state. After transitioning from Reset, the device only returns to the Reset state if the power is cycled, or if the primary side over temperature is detected. The secondary over temperature event does not cause the state transition to RESET unless the primary side also detects the over temperature event. State 2: Configuration 1 Once all of the BIST complete, and communication is established from the primary to the secondary side, the device transitions to the Configuration 1 state. This is indicated when the nFLT* outputs are pulled high. In this state, the address for the device is programmable by the MCU. See the Device Addressing section for details on how to program the SPI address for the device. The driver output (OUTL) is pulled low in this state. Once the address is programmed, the CONFIG_IN command (see ) must be sent to transition to the Configuration 2 state. Note that in Daisy Chain configurations, the CFG_IN must be sent to the devices one-by-one because the SDO output is not enabled until a valid addressed command is sent. This can be done by sending a full frame of 6 CFG_IN commands six times or, alternatively, send a CFG_IN to the first device as a single command followed by CFG_IN, NOP as the second frame, followed by CFG_IN, NOP, NOP as the third frame, and so on to enable the SDO output on all devices and send them to Configuration 2. This process only needs to be done once per power cycle unless an invalid address (non-0x0) is sent. State 3: Configuration 2 When a valid CONFIG_IN command (see ) is received, the device transitions to the Configuration 2 state. In this state, the device configuration is programmable by the MCU via the SPI interface. All of the configuration registers are available for write. The STATUS registers are updated with the status of the device and the nFLT* outputs will indicate any unmasked faults. The ADC does not operate in the Configuration 2 state. The driver output (OUTL) is pulled low in this state. Send a DRV_EN command (see ) to transition to the Active state and enable the driver output. State 4: Active C 20210503 Corrected CONTROL2 bit name yes Upon receiving a valid DRV_EN command, the device transitions to the Active state. In this state, the STATUS2[DRV_EN_RCVD] bit (STATUS2) is set to '1', the CRC for the configuration registers is calculated and stored, SPI writes to most registers are disabled, and the driver outputs are enabled to follow the IN+/IN- inputs, assuming there is no fault condition. All of the registers are Read Only, with the exception of CONTROL2[CLR_STAT_REG], CFG8[IOUT_SEL], and CFG8[CRC_DIS]. Any writes to any other registers/ bits are ignored. The device remains in Active mode until the SW_RESET command is sent, a DRV_DIS command followed by a CONFIG_IN is sent, or a primary side thermal shutdown fault occurs. The SW_RESET command disables the driver and resets all registers except for the driver address, while the DRV_DIS command disables the driver while leaving the register contents intact.

Once the address is programmed, the CONFIG_IN command (see ) must be sent to transition to the Configuration 2 state. Note that in Daisy Chain configurations, the CFG_IN must be sent to the devices one-by-one because the SDO output is not enabled until a valid addressed command is sent. This can be done by sending a full frame of 6 CFG_IN commands six times or, alternatively, send a CFG_IN to the first device as a single command followed by CFG_IN, NOP as the second frame, followed by CFG_IN, NOP, NOP as the third frame, and so on to enable the SDO output on all devices and send them to Configuration 2. This process only needs to be done once per power cycle unless an invalid address (non-0x0) is sent.Device Addressing State 3: Configuration 2 When a valid CONFIG_IN command (see ) is received, the device transitions to the Configuration 2 state.

The SPI communication follows a 16-bit protocol, utilizing specific command data frames, and uses an active-low chip select input (nCS) and communicates at rates up to 4MHz. The communication frame starts with the nCS falling edge and ends with nCS rising edge. While nCS is high, the SPI interface is held in reset, and the SDO output is high impedance. The SPI clock idles at 0 (CPOL=0) and clocks the SDI/SDO data (CPHA=1) on the falling edge. The device supports three SPI bus configurations: independent slave configuration, daisy chain configuration, and a new address oriented configuration. System Configuration of SPI Communication The system is configured in one of the three SPI modes: Regular SPI configuration (), Daisy Chain configuration (), and Address-based onfiguration (). Independent Slave Configuration The Independent Slave configuration is shown in . In this mode, the CLK input, SDI input, and SDO outputs for all devices on the SPI bus are shared. The MCU drives the nCS input for the device that is to be addressed. The drawback to this approach is that a separate GPIO for each driver in the system (up to 12 for dual inverter systems) is required of the MCU, but it does allow random access to any device in the system. The message frame is shown in System configuration of regular SPI configuration SPI message frame for Independent Slave and Address-based configurations Daisy Chain Configuration The Daisy Chain configuration is shown in . In this configuration, the MCU MOSI connects to the SDI of the first device and the MISO connects to the SDO of the last device. The SDO of each of the device connects to the SDI of the next device in the system (excluding the last device). The system effectively becomes a communication shift register. During communication, the host continuously clocks in data for all the devices in the system while holding the nCS pin low. While the nCS input is low, the SDO shifts data out as the data is clocked into the SDI shift register as shown in . Once nCS is pulled high, the 16-bits in the SDI register are latched and acted upon by the device. This configuration drastically reduces the number of GPIOs required, but it does not allow random access to the devices. System configuration of daisy chain SPI configuration SPI message frame daisy chain SPI configuration Address-based Configuration The Address-based configuration provides significant flexibility to the system design. This configuration is similar to the Independent Slave configuration in that all of the CLK, SDO, and SDI connections are shared between all devices (shown in ). Additionally, the nCS input is also shared. This reduces the GPIO requirement on the MCU to one, similar to Daisy Chain, but also allows random access like the Independent Slave configuration. The Address-based configuration is done by defining each device in the system with a unique address. See the Device Addressing section for details on how to address the devices in the system. The message frame is shown in System configuration for Address-based SPI Communication Scheme SPI Data Frame The SPI data frame is composed of 16bits. The timing scheme and format of a data frame is shown in and . Timing scheme of SPI communication 16-bit of SPI data frame. The 16-bit data frame includes three data fields: chip address (CHIP_ADDR), command type (CMD), and an 8-bit data (DATA). The chip address (CHIP_ADDR) bits are used, regardless of the system configuration. However, when using the Daisy Chain or Independent Slave configurations, 0x0 or 0xF is used for all of the devices in the system. In Address-based configuration, the devices are individually addressed, and all devices respond to 0x0 and 0xF. Note that SDO is high impedance until it receives a command with the programmed device address. Once receiving the valid addressed command, the SDO is driven to send out data. When an invalid addressed command or 0xF (broadcast address) is received, the SDO returns to high impedance, thereby allowing other devices to take control of the shared MISO (SDO) bus. There are 10 command types used by the device, defined in .

The SPI engine utilizes three separate commands in order to program these registers. The process involves first setting the register to be written to by using the WR_RA command. All subsequent writes will go to this register address until the WR_RA command is sent again, or the device is reset. Use the WRH command to write the "high" byte of the register (bits 15:8) and use the WRL command to write the "low" byte of the register (bits 7:0). The WRH and WRL commands can be sent in any order. Additionally, it is not necessary to write both bytes of the register. If only the "low" byte needs modification, a WRL write is all that is required. It is not necessary to send a WRH command as well. Reading a Register The process for reading a register is less steps than that of a write command. To read a register, simply use the RD_DATA command to program the device with the register to be read. The full 16-bit data is clocked out during the next SPI transaction. The next SPI transaction could be another command (RD_DATA or WR_RA, for example), or simply a NOP (no operation command). Never send a RD_DATA command to the broadcast address (0xF) while in the Address-based configuration. This will cause all devices on the bus to responds simultaneously and the data will be corrupted. It is ok to use 0xF in the other modes as the traffic is handled by another mechanism.

The 16-bit data frame includes three data fields: chip address (CHIP_ADDR), command type (CMD), and an 8-bit data (DATA). The chip address (CHIP_ADDR) bits are used, regardless of the system configuration. However, when using the Daisy Chain or Independent Slave configurations, 0x0 or 0xF is used for all of the devices in the system. In Address-based configuration, the devices are individually addressed, and all devices respond to 0x0 and 0xF. Note that SDO is high impedance until it receives a command with the programmed device address. Once receiving the valid addressed command, the SDO is driven to send out data. When an invalid addressed command or 0xF (broadcast address) is received, the SDO returns to high impedance, thereby allowing other devices to take control of the shared MISO (SDO) bus.

The SPI engine utilizes three separate commands in order to program these registers. The process involves first setting the register to be written to by using the WR_RA command. All subsequent writes will go to this register address until the WR_RA command is sent again, or the device is reset. Use the WRH command to write the "high" byte of the register (bits 15:8) and use the WRL command to write the "low" byte of the register (bits 7:0). The WRH and WRL commands can be sent in any order. Additionally, it is not necessary to write both bytes of the register. If only the "low" byte needs modification, a WRL write is all that is required. It is not necessary to send a WRH command as well. Reading a Register The process for reading a register is less steps than that of a write command. To read a register, simply use the RD_DATA command to program the device with the register to be read. The full 16-bit data is clocked out during the next SPI transaction. The next SPI transaction could be another command (RD_DATA or WR_RA, for example), or simply a NOP (no operation command). Never send a RD_DATA command to the broadcast address (0xF) while in the Address-based configuration. This will cause all devices on the bus to responds simultaneously and the data will be corrupted. It is ok to use 0xF in the other modes as the traffic is handled by another mechanism. SPI Data Frame The SPI data frame is composed of 16bits.

To read a register, simply use the RD_DATA command to program the device with the register to be read. The full 16-bit data is clocked out during the next SPI transaction. The next SPI transaction could be another command (RD_DATA or WR_RA, for example), or simply a NOP (no operation command).

Upon entering the Configuration 1 state (indicated by nFLT* high, assuming no fault during startup), all devices are addressable 0x1 through 0xE (14 unique addresses), with 0xF being a broadcast address to which all devices respond. Addressing is done in the Configuration 1 state. In this state, the IN+ input is pulled high while the WR_CA command is sent with the defined address. The written address is stored in the GDADDRESS[GD_ADDR] bits (GDADDRESS). Once all devices are addressed, send the CFG_IN command with the broadcast device address (0xF) to lock in the device address and move to configuring the devices (Configuration 2 state).

Design Requirements PARAMETER VALUE UNITS DC Bus Voltage 400 V VCC1 3.3 V VCC2 15 V VEE2 -8 V Switching Frequency 10 kHz Detailed Design Procedure VCC1, VCC2, and VEE2 Bypass Capacitors Use ceramic capacitors between VCC1 and GND1, VCC2 and VGND2, and VEE2 and VGND2. For VCC1, it is recommended to use a 0.1µF capacitor in parallel with a 1µF capacitor. Use at least a 6.3V voltage rating. For VCC2, it is recommended to use a 0.1µF capacitor in parallel with a 1µF capacitor at the pin. Bulk capacitor (>22µF) on the supply rail is required to ensure minimal droop during transitions. Use at least a 50V voltage rating. For VEE2, it is recommended to use a 0.1µF capacitor in parallel with a 1µF capacitor at the pin. Bulk capacitor (>22µF) on the supply rail is required to ensure minimal droop during transitions. Use at least a 25V voltage rating. VREF, VREG1, and VREG2 Bypass Capacitors Connect a ceramic capacitor between VREG1 and GND1, VREG2 and VEE2, and VREF and GND2. For the VREG1 and VREG2 outputs, it is recommended to use a 0.1µF capacitor in parallel with a 4.7µF capacitor at the pin with at least a 6.3V voltage rating. It is recommended to bypass VREF with a 1µF capacitor at the pin with at least a 6.3V voltage rating. Bootstrap Capacitor (VBST) Connect a ceramic capacitor between VBST and OUTH. It is recommended to use a 0.1µF capacitor with at least a 6.3V voltage rating. VCECLP Input The active VCE clamp circuit is used to reduce VCE overshoot voltage during IGBT turn off. The external circuit () uses four components: A high-voltage TVS diode (D1) that turns on (avalanche breakdown) if the VCE overshoot during the IGBT turn-off is greater than the TVS diode avalanche limit, a filter capacitor (CP) that is charged when D1 conducts, a diode (D2) that conducts some of the avalanche current to the IGBT gate to increase the gate voltage (VGE) in order slow down the turn off transient and reduce the VCE overshoot, and a resistor (RC) to set the time constant to discharge the VCECLP node when D1 stops conducting. Select the D1 avalanche voltage rating to be the IGBT VCE overshoot voltage control target. During normal operation, the VCE dV/dt couples to VCECLP through junction capacitance of D1. The CP value is selected to filter this coupled ripple voltage to prevent triggering the VCE clamp function during normal operation. When a VCE over voltage occurs and D1 avalanches, CP charges to the VCECLPth by avalanche current, then VCE clamp function triggers and OUTL driver is disabled while the STO current is enabled. The RP value sets the the RC time constant when the CP voltage drops below VCECLPth. The value of RP depends on the selection of the IGBT, D1, RGON, RGOFF. Typically, the Rp value is between 10 to 100 ohm and CP value is between 10nF to 100nF. There is not a hard and fast calculation for these components. The best method is experimenting to fine tune the components for best performance in the application. See for an example of performance with the UCC5870QDWJEVM-026 () EVM. VCECLP External Components External CLAMP Output When using an external Miller clamp, select a MOSFET with the required RDSON for the desired pulldown strength. Connect CLAMP to the gate of the pulldown transistor, the drain to the gate of the external power FET, and the source to GND2 at the external power FET. AI* Inputs AI* require a series resistor and bypass capacitor (RC filter) to ensure best results. The values must be selected based on the required corner frequency for the input. A tradeoff must be made between response time, in the case of SCP and OCP monitoring, and the noise during ADC measurements. The DC input impedance of the AI* inputs is very high. However, as the signal frequency goes up, the input impedance decreases. The input impedance can be estimated as: ZAI* = sqrt(8kΩ2 + (1 /( 2π × fS × 1.5pF))2) Where fS is the frequency of the signal. The filter The recommended RC for OCP/SCP monitoring is 100ohm and 100pF. This provides a quicker response with the drawback of more noise in the measurement. The RC chosen for the other inputs used in the application circuits is 10ohm and 10nF. All of the ADC data taken on these inputs in this datasheet are based on those RC values. For best results for ADC accuracy, it is recommended to use these components. If a different corner frequency is required, select a frequency that provides sufficient accuracy with the decreased AI* input impedance. The corner frequency is calculated using the following equation: fC = 1/ (2πRC) OUTH/ OUTL Outputs The OUTH and OUTL outputs provide split gate drive to customize the turn-on and turn-off rates to customize applications for limiting noise and ringing. A resistor from OUTH and from OUTL to the gate of the power transistor set the rise/fall time of the gate drive to the power transistor. To set the rise time, select the resistor (RG) for OUTH and OUTL to the gate according to the following equation: RG=ωLS/ Q Where LS is the inductance of the gate and Q is the quality factor between 0.5 (critically damped) and 1 (under damped). See SLLA385 () for additional information on gate resistor design. It is required that the value or RG must be greater than 1.5Ω for both OUTH and OUTL. nFLT* Outputs The nFLT1 and nFLT2 indicators are open-drain outputs, connect a 1k to 100k resistor from nFLT* to VCC1 to set the correct logic level. Application Curves IGBT Double Pulse Waveform SiC Double Pulse Waveform VCE Clamp Response with 100ns Hold Time Typical Application Using DESAT Power FET Monitoring Typical Application Circuit using DESAT Overcurrent Protection Detailed Design Procedure See the previous section on details for selection of external components. DESAT Input The DESAT circuit monitors the power module (IGBT for example) for short circuit or over current protection. The external circuit includes four components (): blanking capacitor (CBLK), clamping diode (DCLP), series resistor RS and high-voltage blocking diode (DHV). CBLK is used to determine the blanking time, tBLK. The time period for tBLK must be long enough to prevent a false trigger when the during the normal operation turn-on cycle. tBLK is calculated as: tBLK = CBLK × VDESATth/ ICHG The high voltage diode DHV blocks the high voltage (VCE) while IGBT is OFF. The voltage rating for DHV must be higher than the DC bus voltage plus any switching transient voltage. It is good practice to choose a voltage rating for DHV to be the same or higher than the IGBT voltage rating. Once the proper voltage rating is determined, choose a diode with the least amount of junction capacitance to prevent coupling of DESAT with the dV/dt of the VCE switching. Clamping diode, DCLP, provides a current path to for any coupling current due to the aforementioned junction capacitance of DHV. Select a diode large enough to handle any expected coupling current. The series resistor, RS, dampens any oscillations in the DESAT loop and determines the actual DESAT detection VCE voltage. The actual threshold is calculated as: VDESAT,ACTUAL = VDESATth - ICHG × RS - VDHV VDHV is the forward voltage drop of the DHV diode and ICHG is the blanking capacitor charging current selected using the CFG5[DESAT_CHG_CURR] bits.

Design Requirements PARAMETER VALUE UNITS DC Bus Voltage 400 V VCC1 3.3 V VCC2 15 V VEE2 -8 V Switching Frequency 10 kHz Detailed Design Procedure VCC1, VCC2, and VEE2 Bypass Capacitors Use ceramic capacitors between VCC1 and GND1, VCC2 and VGND2, and VEE2 and VGND2. For VCC1, it is recommended to use a 0.1µF capacitor in parallel with a 1µF capacitor. Use at least a 6.3V voltage rating. For VCC2, it is recommended to use a 0.1µF capacitor in parallel with a 1µF capacitor at the pin. Bulk capacitor (>22µF) on the supply rail is required to ensure minimal droop during transitions. Use at least a 50V voltage rating. For VEE2, it is recommended to use a 0.1µF capacitor in parallel with a 1µF capacitor at the pin. Bulk capacitor (>22µF) on the supply rail is required to ensure minimal droop during transitions. Use at least a 25V voltage rating. VREF, VREG1, and VREG2 Bypass Capacitors Connect a ceramic capacitor between VREG1 and GND1, VREG2 and VEE2, and VREF and GND2. For the VREG1 and VREG2 outputs, it is recommended to use a 0.1µF capacitor in parallel with a 4.7µF capacitor at the pin with at least a 6.3V voltage rating.

It is recommended to use a 0.1µF capacitor with at least a 6.3V voltage rating. VCECLP Input The active VCE clamp circuit is used to reduce VCE overshoot voltage during IGBT turn off. The external circuit () uses four components: A high-voltage TVS diode (D1) that turns on (avalanche breakdown) if the VCE overshoot during the IGBT turn-off is greater than the TVS diode avalanche limit, a filter capacitor (CP) that is charged when D1 conducts, a diode (D2) that conducts some of the avalanche current to the IGBT gate to increase the gate voltage (VGE) in order slow down the turn off transient and reduce the VCE overshoot, and a resistor (RC) to set the time constant to discharge the VCECLP node when D1 stops conducting. Select the D1 avalanche voltage rating to be the IGBT VCE overshoot voltage control target. During normal operation, the VCE dV/dt couples to VCECLP through junction capacitance of D1. The CP value is selected to filter this coupled ripple voltage to prevent triggering the VCE clamp function during normal operation. When a VCE over voltage occurs and D1 avalanches, CP charges to the VCECLPth by avalanche current, then VCE clamp function triggers and OUTL driver is disabled while the STO current is enabled. The RP value sets the the RC time constant when the CP voltage drops below VCECLPth. The value of RP depends on the selection of the IGBT, D1, RGON, RGOFF. Typically, the Rp value is between 10 to 100 ohm and CP value is between 10nF to 100nF. There is not a hard and fast calculation for these components. The best method is experimenting to fine tune the components for best performance in the application. See for an example of performance with the UCC5870QDWJEVM-026 () EVM. VCECLP External Components External CLAMP Output When using an external Miller clamp, select a MOSFET with the required RDSON for the desired pulldown strength. Connect CLAMP to the gate of the pulldown transistor, the drain to the gate of the external power FET, and the source to GND2 at the external power FET. AI* Inputs AI* require a series resistor and bypass capacitor (RC filter) to ensure best results. The values must be selected based on the required corner frequency for the input. A tradeoff must be made between response time, in the case of SCP and OCP monitoring, and the noise during ADC measurements. The DC input impedance of the AI* inputs is very high. However, as the signal frequency goes up, the input impedance decreases. The input impedance can be estimated as: ZAI* = sqrt(8kΩ2 + (1 /( 2π × fS × 1.5pF))2) Where fS is the frequency of the signal. The filter The recommended RC for OCP/SCP monitoring is 100ohm and 100pF. This provides a quicker response with the drawback of more noise in the measurement. The RC chosen for the other inputs used in the application circuits is 10ohm and 10nF. All of the ADC data taken on these inputs in this datasheet are based on those RC values. For best results for ADC accuracy, it is recommended to use these components. If a different corner frequency is required, select a frequency that provides sufficient accuracy with the decreased AI* input impedance. The corner frequency is calculated using the following equation: fC = 1/ (2πRC) OUTH/ OUTL Outputs The OUTH and OUTL outputs provide split gate drive to customize the turn-on and turn-off rates to customize applications for limiting noise and ringing. A resistor from OUTH and from OUTL to the gate of the power transistor set the rise/fall time of the gate drive to the power transistor. To set the rise time, select the resistor (RG) for OUTH and OUTL to the gate according to the following equation: RG=ωLS/ Q Where LS is the inductance of the gate and Q is the quality factor between 0.5 (critically damped) and 1 (under damped). See SLLA385 () for additional information on gate resistor design. It is required that the value or RG must be greater than 1.5Ω for both OUTH and OUTL. nFLT* Outputs The nFLT1 and nFLT2 indicators are open-drain outputs, connect a 1k to 100k resistor from nFLT* to VCC1 to set the correct logic level.

VCECLP External Components The active VCE clamp circuit is used to reduce VCE overshoot voltage during IGBT turn off. The external circuit () uses four components: A high-voltage TVS diode (D1) that turns on (avalanche breakdown) if the VCE overshoot during the IGBT turn-off is greater than the TVS diode avalanche limit, a filter capacitor (CP) that is charged when D1 conducts, a diode (D2) that conducts some of the avalanche current to the IGBT gate to increase the gate voltage (VGE) in order slow down the turn off transient and reduce the VCE overshoot, and a resistor (RC) to set the time constant to discharge the VCECLP node when D1 stops conducting. Select the D1 avalanche voltage rating to be the IGBT VCE overshoot voltage control target. During normal operation, the VCE dV/dt couples to VCECLP through junction capacitance of D1.

Layout Layout Guidelines One must pay close attention to PCB layout in order to achieve optimum performance for the device. Component Placement Low-ESR and low-ESL capacitors must be connected close to the device between the VCC1 and GND1 pins and between the VCC2, VEE2 and GND2 pins to support high peak currents when turning on the external power transistor. Place the VBST and VREF caps as close to the device as possible. Grounding Considerations It is essential to confine the high peak currents that charge and discharge the transistor gates to a minimal physical area. This decreases the loop inductance and minimize noise on the gate terminals of the transistors. The gate driver must be placed as close as possible to the transistors. Pay attention to high current path that includes the bootstrap capacitor. The bootstrap capacitor is recharged on a cycle-by-cycle basis through the diode by the VCC2 bypass capacitor. This recharging occurs in a short time interval and involves a high peak current. Minimizing this loop length and area on the circuit board is important for ensuring reliable operation. High-Voltage Considerations To ensure isolation performance between the primary and secondary side, one should avoid placing any PCB traces or copper below the driver device. A PCB cutout is recommended in order to prevent contamination that may compromise the UCC51870’s isolation performance. For half-bridge, or high-side/low-side configurations, where the high-side and low-side drivers could operate with a DC-link voltage up to 1000 VDC, one should try to increase the creepage distance of the PCB layout between the high and low-side PCB traces. Thermal Considerations The power dissipated by the device is directly proportional to the drive voltage, heavy capacitive loading, and/or high switching frequency (refer to Power Dissipation Considerations section for more details). Proper PCB layout helps dissipate heat from the device to the PCB and minimize junction to board thermal impedance (θJB). Increasing the PCB copper connecting to VCC2 and VEE2 is recommended, with priority on maximizing the connection to VEE2. However, high voltage PCB considerations mentioned above must be maintained. If there are multiple layers in the system, it is also recommended to connect the VCC2 and VEE2 to internal ground or power planes through multiple vias of adequate size. However, keep in mind that there shouldn’t be any traces/coppers from different high voltage planes overlapping.

Thermal Considerations The power dissipated by the device is directly proportional to the drive voltage, heavy capacitive loading, and/or high switching frequency (refer to Power Dissipation Considerations section for more details). Proper PCB layout helps dissipate heat from the device to the PCB and minimize junction to board thermal impedance (θJB). Increasing the PCB copper connecting to VCC2 and VEE2 is recommended, with priority on maximizing the connection to VEE2. However, high voltage PCB considerations mentioned above must be maintained. If there are multiple layers in the system, it is also recommended to connect the VCC2 and VEE2 to internal ground or power planes through multiple vias of adequate size. However, keep in mind that there shouldn’t be any traces/coppers from different high voltage planes overlapping.

Grounding Considerations It is essential to confine the high peak currents that charge and discharge the transistor gates to a minimal physical area. This decreases the loop inductance and minimize noise on the gate terminals of the transistors. The gate driver must be placed as close as possible to the transistors. Pay attention to high current path that includes the bootstrap capacitor. The bootstrap capacitor is recharged on a cycle-by-cycle basis through the diode by the VCC2 bypass capacitor. This recharging occurs in a short time interval and involves a high peak current. Minimizing this loop length and area on the circuit board is important for ensuring reliable operation.
