BATTERY PROTECTION IC FOR 1-CELL PACK
Rev.1.1_03
The S-8250B Series is a protection IC for 1-cell lithium-ion / lithium polymer rechargeable batteries and includes high-accuracy voltage detection circuits and delay circuits. The S-8250B Series is suitable for protecting 1-cell lithium-ion / lithium polymer rechargeable battery packs from overcharge, overdischarge and overcurrent. By adjusting power supply voltage dependency of discharge overcurrent detection voltage in accordance with ON resistance of the charge-discharge control FET, the S-8250B Series realizes high-accuracy discharge overcurrent detection.
Features
High-accuracy discharge overcurrent detection circuit
Discharge overcurrent detection voltage 0.050 V to 0.
