(if a device without 0v charging fun ction is needed, please contact diodes sales team) 7. over v oltage charger detection circuit this function is used to monitor the charger voltage between the v dd pin and v m pin, and when this voltage exceeds overvoltage charger detection voltage (8.0v typ.), the ap9234l will turn off charging mosfet, when this voltage drops below overvoltage charger release voltage (7.3v typ.) , it then turn s on charging mosfet. there are no delay times set for detection and release. 8. power - down mode or auto - wake - up function option in device with power - down function, during p ower - down mode, ap9234l enters overdischarge status. the ic enters sleep mode and the current consumption becomes very low , typically 0.1ua . to release from power - down status to the normal status, charger connection is required. in device with auto - wakeup mode, t he ic remains active in the o verdischarge state. the ic is released into the normal state by the operation that increases the battery voltage more than o verdischarge release voltage.
