Hello!
Chapter 9.3.20.1 /PROCHOT During Low Power Mode of bq25730 datasheet says:
When EN_PROCHOT_LPWR = 1b, charger monitors system voltage. Connect CMPIN to voltage
proportional to system voltage. PROCHOT triggers from HIGH to LOW when CMPIN voltage rises above
1.2 V.
Should it be:
When EN_PROCHOT_LPWR = 1b, charger monitors system voltage. Connect CMPIN to voltage
proportional to system voltage. PROCHOT triggers from HIGH to LOW when CMPIN voltage drops below
1.2 V.
The same chapter also says that Independent comparator threshold is always 1.2 V though the default value of the comparator reference voltage is 2.3V according to Table 9-29. ChargeOption1 Register.
