General Description

The APL3208A/B/C provides complete Li+ charger protection against Input over-voltage, battery over-voltage, and the charge current limit. When the input OVP or the battery OVP is over the threshold, the IC removes the power from the charging system by turning off an internal switch. When the current via the internal switch surpasses the current limit threshold, the current will be clamped in a constant level to provide a constant current for battery charging usage. All protections also have deglitch time against false triggering due to voltage spikes or current transients.
