ABLIC S-8211CAD-M5T1G

The S-8211C series is a protection IC for single-cell lithium-ion/lithium-polymer rechargeable batteries, incorporating a high-accuracy voltage detection circuit and delay circuit. This series is designed to protect single-cell lithium-ion/lithium-polymer rechargeable battery packs from overcharge, overdischarge, and overcurrent damage.

• High-precision voltage detection circuit: overcharge detection voltage range 3.9 V to 4.5 V (5 mV steps), accuracy ±25 mV (Ta=+25℃), accuracy ±30 mV (Ta=-5℃ to +55℃); overcharge release voltage range 3.8 V to 4.43 V, accuracy ±50 mV; overdischarge detection voltage range 2.0 V to 3.0 V (10 mV steps), accuracy ±50 mV; overdischarge release voltage range 2.0 V to 3.4 V, accuracy ±100 mV; discharge overcurrent detection voltage range 0.05 V to 0.30 V (10 mV steps), accuracy ±15 mV; load short-circuit detection voltage fixed at 0.5 V, accuracy ±200 mV; charge overcurrent detection voltage fixed at -0.1 V, accuracy ±30 mV.
• Detection delay time generated by internal circuitry only (no external capacitor required), accuracy ±20%.
