General  Description
The APL3225provides complete Li+ charger protection against input over-voltage, input over-current and over temperature. When any of the monitored parameters is over the threshold, the IC turns off the charging current. All protections also have deglitch time against false triggering due to voltage spikes or current transients.
The APL3225 integrates a 5.5V LDO to prevent ACIN over shoot reaching CHR_LDO and OUT. When any transient peak voltage above 5.5V presenting inACIN pin, but be low OVP threshold, the internal LDO will clamp its output at 5.5V . When ACIN voltage exceeds OVP threshold, the
device will turn off charging current. The charging current is controlled by the GATDRV pin. When sourcing a current from the GATDRV pin, the OUT pin delivers the charging current which is 200-fold magnified in amplitude based on GATDRV’ s current.
