ABLIC S-8211DAS-M5T1U

The S-8211D Series is a protection IC for 1-cell lithium-ion / lithium-polymer rechargeable batery and includes high-accuracy voltage detection circuits and delay circuits. The S-8211D Series is suitable for protecting 1-cell rechargeable lithium-ion / lithium-polymer battery packs from overcharge, overdischarge, and overcurrent.

• High-accuracy voltage detection circuit
  • Overcharge detection voltage 3.6 V to 4.5 V (5 mV step), Accuracy ±25 mV (Ta = +25°C), Accuracy ±30 mV (Ta = -5°C to +55°C)
  • Overcharge release voltage 3.5 V to 4.4 V, Accuracy ±50 mV
  • Overdischarge detection voltage 2.0 V to 3.0 V (10 mV step), Accuracy ±50 mV
