PRODUCTION DATA
In INITIALIZE state, the device is completely shut down with the exception of a few circuits to monitor the EN/PB/VSENSE input. Whenever entering the INITIALIZE state, the PMIC reads the memory and loads the registers to their EEPROM-default values. The I2C communication interface is turned off .
Entry to INITIALIZE state is gated if any one of the thermal sensors is above the TWARM_Rising threshold and WARM-detection is not masked.
The EEPROM loading takes approximately 2.3 ms. The power-up sequence can only execute after the EEPROM-load and if all rails are discharged below the VBUCKx_SCG_TH respectively VLDOx_SCG_TH threshold.
If INITIALIZE state was entered from OFF state, bit POWER_UP_FROM_OFF in POWER_UP_STATUS_REG register is set and remains set until a write-1-clear is issued. Read-out of this bit allows to determine if INITIALZE state was entered from OFF state or due to a Shut-down-fault or OFF-request.
In INITIALIZE state, the nINT pin status is dependent if faults are and masking thereof. If no faults are present or nINT-reaction for those are masked, nINT-pin is pulled high, provided a VIO-voltage for the pull-up is available.
To transition from the INITIALIZE state to the ACTIVE state, one of the ON-requests must occur:
