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.
