Li+ Charger Protection ICThe APL3212A/B/C provide complete Li+ charger protections
against over-voltage, over-current, and battery overvoltage.
The IC is designed to monitor input voltage, input
current, and battery voltage. When any of the monitored
parameters are over the threshold, the IC removes
the power from the charging system by turning off an internal
switch. All protections also have deglitch time
against false triggering due to voltage spikes or current
transients. The APL3212A/B/C also provide over-temperature
protection, a FAULT output pin to indicate the fault
conditions, and the EN pin to allow the system to disable
