The APL3206/A/B provides complete Li+ charger protec-

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

battery over-voltage. When any of the monitored param-

eters are over the threshold, the IC removes the power

from the charging system by turning off an internal switch.

All protections also have deglitch time against false trig-

gering due to voltage spikes or current transients.

The APL3206/A/B integrates a P-MOSFET with the body

diode 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 VBAT+20mV,

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 APL3206/A/B 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 APL3206/A/B an ideal part

for cell phones applications.
