If the PROCHOT pulse extension mode is enabled by setting EN_PROCHOT_EXT= 1b, the PROCHOT pin will

be kept low until host writes PROCHOT_CLEAR= 0b, even if the triggering event has been removed.

If the PROCHOT_VINDPM or PROCHOT_EXIT_VAP is triggered, PROCHOT pin will always stay low until

the host clears it, no matter the PROCHOT is in one pulse mode or in extended mode. In order to clear

PROCHOT_VINDPM, host needs to write 0 to STAT_VINDPM. In order to clear PROCHOT_EXIT_VAP, host

needs to write 0 to STAT_EXIT_VAP.

Figure 8-4. PROCHOT Profile

8.3.20.1 PROCHOT During Low Power Mode

During low power mode (EN_LWPWR = 1), the charger offers a low power PROCHOT function with very low

quiescent current consumption (~35 μA), which uses the independent comparator to monitor the system voltage,

and assert PROCHOT to CPU if the system power is too high and resulting system voltage is lower than specific

threshold.
