The APL3204A/B provide complete Li+ charger protec-

tions against over-voltage, over-current, and battery over-

voltage. The IC is designed to monitor input voltage, in-

put current, and battery voltage. When any of the moni-

tored parameters are over the threshold, the IC removes

the power from the charging system by turning off an in-

ternal switch. All protections also have deglitch time

against false triggering due to voltage spikes or current

transients. The APL3204A/B also provide over-tempera-

ture protection, a FAULT output pin to indicate the fault

conditions, and the EN pin to allow the system to disable

the IC.
