Voltage Clamping Protection
General Description
The APL3225 provides complete Li+ charger protection against input over-
voltage, input over-current and overtemperature.
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 overshoot reaching CHR_LDO and OUT.
When any transient peak
voltage above 5.
5V presenting in ACIN pin, but below OVP threshold, the internal LDO will clamp its output at 5.
5V.
