Other Parts Discussed in Thread: BQ24160,
Does the BQ25798 have a reverse boost protect feature like the BQ24160 has?
I did not see any mention of this feature on the datasheet, but I have experienced a problem with other models using the BQ24160 not detecting the end of charge when the cutoff current is set to less than 150mA, may the BQ25798 experience similar symptoms?
The reverse boost protect function does not detect the end of charging:
* The reverse boost protect function prevents reverse current from flowing into the input side and damaging the IC when the battery voltage (VBAT) becomes higher than the system voltage (VBATREG).
* When this function is activated, the IC stops charging, but the end-of-charge detection is disabled because the charging current does not stop due to a drop in charge current.
* When this function is activated, a ripple is generated in the system voltage every 1ms, and the battery is discharged.
* The possibility of this function working increases when the end-of-charge current is set to less than 150 mA or when a low-impedance battery is used.
