1 / 20 page Copyright © ANPEC Electronics Corp. Rev. A.2 - Sep., 2013 APL3212A/B/C www.anpec.com.tw 1 ANPEC reserves the right to make changes to improve reliability or manufacturability without notice, and advise customers to obtain the latest version of relevant information to verify before placing orders. Li+ Charger Protection IC • Provide Input Over-Voltage Protection • Programmable Input Over-Current Protection • Battery Over-Voltage 4.35V/4.435V 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 (RoHS Compliant) The APL3212A/B/C provide complete Li+ charger protec- tions against over-voltage, over-current, and battery over- voltage. The IC is designed to monitor input voltage, in- put current, and battery voltage. When any of the moni- tored parameters are over the threshold, the IC removes the power from the charging system by turning off an in- ternal switch. All protections also have deglitch time against false triggering due to voltage spikes or current transients. The APL3212A/B/C also provide over-tempera- ture protection, a FAULT output pin to indicate the fault conditions, and the EN pin to allow the system to disable the IC.
