Li+ Charger Protection IC with Integrated P-MOSFET

(RoHS Compliant)

Features

Applications

General Description

Simplified Application Circuit

The APL3215/A provides complete Li+ charger protection

against input over-voltage, input over-current, and battery

over-voltage. When any of the monitored parameters are

over the threshold, the IC removes the power from the

charging system by turning off an internal switch. All pro-

tections also have deglitch time against false triggering

due to voltage spikes or current transients.

The APL3215/A integrates a P-MOSFET with the body di-

ode reverse protection to replace the external P-MOSFET

and Schottky diode for charger function of cell phone’s

PMIC. When the CHRIN voltage drops below V

the internal power select circuit will reverse the body

diode’s terminal to prevent a reverse current flowing from

the battery back to CHRIN pin.

The APL3215/A provides complete Li+ charger protec-

tions and saves the external MOSFET and Schottky diode

for the charger of cell phone’s PMIC. The above features

and small package make the APL3215/A an ideal part for

cell phones applications.
