Features - - - - - - - - - - Input Over-Voltage Protection Programmable Input Over-Current Protection Battery Over-Voltage Protection Over-Temperature Protection High Immunity of False Triggering High Accuracy Protection Thresholds Fault Status Indication Enable Input Available in TDFN2x2-8 Package Lead Free and Green Devices Available (Ro HS pliant) General Description The APL3203A/B/C provide plete Li+ charger protections against over-voltage, over-current, and battery overvoltage. The IC is designed to monitor input voltage, input current, and battery 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 protections also have deglitch time against false triggering due to voltage spikes or current transients. The APL3203A/B/C also provide over-temperature protection, a FAULT output pin to indicate the fault conditions, and the EN pin to allow the system to disable the IC.
