APL3225 - Li+ Charger Protector

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.

Key Features

  • Provide OUT Pin 5V Voltage Clamping Protection General.

APL3225 Li+ Charger Protection IC Features • • • • • • • • • • Provide OUT Pin 5V 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. When ACIN voltage exceeds OVP threshold, the device will turn off charging current.
