Rev.2.1_00 BATTERY PROTECTION IC FOR 2-SERIAL OR 3-SERIAL-CELL PACK S-8253A/B Series The S-8253A/B Series are protection ICs for 2-serial or 3-serial cell lithium-ion rechargeable batteries and include high-accuracy voltage detectors and delay circuits. These ICs are suitable for protecting lithium-ion battery packs from overcharge, overdischarge and overcurrent. Features (1) High-accuracy voltage detection for each cell • • Overcharge detection voltage n (n = 1 to 3) 3.9 V to 4.4 V (50 mV steps) Accuracy ±25 mV *1 Accuracy ±50 mV Overcharge release voltage n (n = 1 to 3) 3.8 V to 4.4 V *1. Overcharge release voltage = Overcharge detection voltage − Overcharge hysteresis voltage (Overcharge hysteresis voltage n (n = 1 to 3) can be selected as 0 V or from a range of 0.1 V to 0.
