Hi Team,
just want to check the actions when batfet is discharging too high current which trigger batocp. Thanks.

Hi Given,
The battery IBAT OCP fault flag triggers if discharge current > 9A min occurs. Because of the battery FET body diode, the BATFET cannot stop the discharge current. If an external shipFET is installed, shipFET present bit (REG0x14[7]) =1 and EN_IBATdicharge_OCP bit (REG0x14[0]) = 1, SDRV charge pump to shipFET gate turns off and shipFET turns off no faster than its turn off time.
Regards,
Jeff
