7.3.8.4 Battery Overcurrent Protection

In order to protect the device from overcurrent and prevent excessive battery discharge current, the device detects if the discharge current on the BATFET exceeds IBAT_OCP. If the IBAT_OCP is reached, the BATFET is turned off and the device starts operating in hiccup mode, re-enabling the BATFET tREC_SC (250 ms) after being turned OFF by the overcurrent condition. If the overcurrent condition is triggered upon retry for 4 to 7 consecutive times in a 2-s window, the BATFET remains off until a valid VIN is connected (VIN_PGOOD). If the overcurrent condition and hiccup operation occur while in supplement mode where VIN is already present, VIN must be toggled in order for the BATFET to be enabled and start another detection cycle.
