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. The APL3225 integrates a 5.5V LDO to prevent ACIN over- shoot reaching CHR_LDO and OUT. When any transient peak voltage above 5.5V presenting in ACIN pin, but be- low 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. The charging current is controlled by the GATDRV pin. When sourcing a cur- rent from the GATDRV pin, the OUT pin delivers the charg- ing current which is 200-fold magnified in amplitude based on GATDRV’s current. Other features include accurate V VCDT/VACIN voltage divider, reverse current blocking from OUT to ACIN and OTP protection. The APL3225 provides complete Li+ charger protections, and saves the external MOSFET and Schottky diode for the charger of cell phone’s PMIC. The above features and small package make the APL3225 an ideal part for cell phones applications.
