S-8201

Rev.2.0_00 www.DataSheet4U.com BATTERY PROTECTION IC FOR SINGLE-CELL PACK S-8201 Series The S-8201 Series are lithium-ion/lithium polymer rechargeable battery protection ICs incorporating highaccuracy voltage detection circuit and delay circuit. The S-8201 Series are suitable for protection of singlecell lithium ion/lithium polymer battery packs from overcharge, overdischarge and overcurrent. „ Features (1) Internal high accuracy voltage detection circuit Overcharge detection voltage 3.9 V to 4.4 V (5 mV step), Accuracy ±25 mV (+25 °C), ±30 mV (−5 °C to +55 °C) *1 Overcharge release voltage 3.8 V to 4.4 V , Accuracy ±50mV Overdischarge detection voltage 2.0 V to 3.0 V (10 mV step), Accuracy ±50 mV *2 Overdischarge release voltage 2.0 V to 3.4 V , Accuracy ±100 mV Overcurrent 1 detection voltage 0.05 V to 0.3 V (10 mV step) Accuracy ±15 mV Overcurrent 2 detection voltage 0.5 V (fixed) Accuracy ±100 mV (2) High voltage device is used for charger connection pins. (VM pin and CO pin: Absolute maximum rating=28 V) (3) Delay times (Overcharge: tCU, Overdischarge: tDL, Overcurrent 1: tlOV1, Overcurrent 2: tlOV2) are generated by an internal circuit. (No external capacitor is necessary.) Accuracy ±20% (4) The overcharge timer reset delay time (7 ms to 40 ms) is generated by an internal circuit only. (No external capacitor is necessary.) (5) Three-step overcurrent detection circuit is included. (Overcurrent 1, Overcurrent 2, Load short-circuiting) (6) Either charge fun...
