PRODUCTION DATA
The events monitored by the processor hot function includes:
The threshold of ICRIT, IDCHG1,IDCHG2,VSYS or VINDPM, and the deglitch time of ICRIT, INOM, IDCHG1, IDCHG2, or CMPOUT are programmable through I2C register bits. Except the PROCHOT_EXIT_VAP is always enabled, the other triggering events can be individually enabled in ProchotOption1[7:0], PP_IDCHG2 and PP_VBUS_VAP. When any enabled event in PROCHOT profile is triggered, PROCHOT is asserted low for a single pulse with minimal width programmable in PROCHOT_WIDTH register bits. At the end of the single pulse, if the PROCHOT event is still active, the pulse gets extended until the event is removed.
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.
