General Description
The APL3216 provides complete Li+ charger protection
against Input over-voltage, input over-current and over-
temperature. 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 trig-
gering due to voltage spikes or current transients.
When ACIN voltage exceeds OVP threshold, the device
will turn off charging current. The charging current is con-
trolled by the GATDRV pin. When sourcing a current from
the GATDRV pin, the OUT pin delivers the charging cur-
rent which is 200-fold magnified in amplitude based on
GATDRV’s current.
Other features include accurate V_VCDT/V_ACIN Voltage divider,
reverse current blocking from OUT to ACIN and OTP
protection. The L3216 provides complete Li+ charger
protections, that can save the external components for
the charger of cell phone’s PMIC. The above features
and small package make the APL3216 an ideal part for
cell phones applications.
