S8241ABPMC

Rev.4.1_01 BATTERY PROTECTION IC FOR 1- CELL PACK S-8241 Series The S-8241 Series is a series of lithium-ion/lithium polymer rechargeable battery protection ICs incorporating high-accuracy voltage detection circuits and delay circuits. These ICs are suitable for protection of single-cell lithium ion/lithium polymer battery packs from overcharge, overdischarge and overcurrent. www.DataSheet4U.com „ Features (1) Internal high-accuracy voltage detection circuit Overcharge detection voltage: 3.9 V to 4.4 V (5 mV-step) Accuracy of ± 25 mV(+25°C) and ± 30 mV(−5°C to +55°C) Overcharge release voltage 3.8 V to 4.4 V *1 Accuracy of ±50 mV *1. Overcharge release voltage = Overcharge detection voltage - Overcharge hysteresis The overcharge hysteresis can be selected in the range 0.0, or 0.1 to 0.4 V in 50mV steps. (However, selection "Overcharge release voltage<3.8 V" is enabled.) Overdischarge detection voltage: Overdischarge release voltage: 2.0 V to 3.0 V (100 mV-step) Accuracy of ±80 mV 2.0 V to 3.4 V *2 Accuracy of ±100 mV Overcurrent 1 detection voltage: 0.05 V to 0.3 V (5 mV-step) Accuracy of ±20 mV Overcurrent 2 detection voltage: 0. 5 V (fixed) Accuracy of ±100 mV (2) A high voltage withstand device is used for charger connection pins (VM and CO pins: Absolute maximum rating = 26 V) (3) Delay times (overcharge: tCU; overdischarge: tDL; overcurrent 1: tlOV1; overcurrent 2: tlOV2) are generated by an internal circuit. (External capacitors are unnecessary.) Acc...
