When a battery is in normal operation status and the voltage at V– pin is lower than the charge overcurrent detection due to high charge current for a time greater than charge overcurrent detection delay, the COUT pin is pulled low to turn OFF the charge FET and prevent further charging to continue. This is known as charge overcurrent status.

The device is restored to normal status from charge overcurrent status when the voltage at the V– pin returns to charge overcurrent detection voltage or higher by removing the charger from the system.

The charge overcurrent detection feature does not work in the over-discharge status.

The resistance R_V–D between V– and BAT and the current sink I_V–S is not connected in the charge overcurrent status.
