Hi all,
Can anyone advice how BQ24257 handle with short-circuit at VBAT-Gnd?
Also, can it detect if its charging a diode in forward biase ( VBAT to anode, Gnd to Cathode of a diode)? And how fast can it respond?

Hello Eddy,
The bq24257 charging IC does not have a protection circuit for VBAT short to ground. It does protect the reverse current from the VBAT to VIN.
Thanks,
