AP9214L

7. Overvoltage Charger Detection Circuit

This function is used to monitor the charger voltage between the VDD pin and VM pin, and when this voltage exceeds overvoltage charger

detection voltage (8.0V Typ.), the AP9214L will turn off charging MOSFET, when this voltage drops below overvoltage charger release voltage

(7.3V Typ.), it then turns on charging MOSFET. There is no delay time setting for detection and release.

8. Power-Down Mode or Auto-Wake-Up Function (Optional)

In device with power-down function, during power-down mode, device enters the overdischarge status. The IC enters sleep mode and the current

consumption becomes very low, typically 0.1

μA. To release from power-down status to the normal status, charger connection is required.

In device with auto-wakeup mode, the IC remains active in the overdischarge state. The IC is released into the normal state by the operation that

increases the battery voltage more than overdischarge release voltage.
