General Description
The APL3206/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 APL3206/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
BAT
+20mV,
the internal power select circuit will reverse the body
diode’ terminal to prevent a reverse current flowing from
s
the battery back to CHRIN pin.
The APL3206/A provides complete Li+ charger protec-
tions and saves the external MOSFET and Schottky diode
for the charger of cell phone’ PMIC. The above features
s
and small package make the APL3206/A an ideal part for
cell phones applications.
