S-8243A

S-8243A/B Series www.ablicinc.com © ABLIC Inc., 2002-2016 BATTERY PROTECTION IC FOR 3-SERIAL OR 4-SERIAL CELL PACK Rev.3.1_01 The S-8243A/B Series is a protection IC for lithium-ion rechargeable battery. The S-8243A Series protects 3-series, the S-8243B Series protects 4-series cell pack from the overcharge, overdischarge, overcurrent voltages. This IC has a high-accuracy battery protection circuit and a battery monitor amplifier, and also a voltage regulator which operates the microcomputer or gas gauge IC. Combining this IC and a microcomputer or a gas gauge IC allows to display the amount of charge remained in a battery.  Features (1) High-accuracy voltage detection for each cell  Overcharge detection voltage n (n = 1 to 4) 3.9 V to 4.4 V (50 mV step) Accuracy 25 mV  Overcharge hysteresis voltage n (n = 1 to 4) of overcharge detection 0.10 V to 0.40 V (50 mV step) or 0 V Accuracy 50 mV (Overcharge release voltage n (= Overcharge detection voltage n ...
