General Description
The APL3205A/B provide completed 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 APL3205A/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.
