Li+ Charger Protection IC with Integrated P-MOSFET • Input Over-Voltage Protection • Input Over-Current Protection • Battery Over-Voltage Protection • High Immunity of False Triggering • High Accuracy Protection Threshold • ABuilt-InP-MOSFET • Thermal Shutdown Protection • Available in a TDFN2x2-8 Package • Lead Free and Green Devices Available (RoHS Compliant) Features Applications • Cell Phones 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 BAT+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 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.
