The S-8261 Series is a lithium-ion / lithium polymer rechargeable battery protection IC incorporating high-accuracy voltage detection circuit and delay circuits. The S-8261 Series is suitable for protection of single-cell lithium-ion / lithium polymer battery packs from overcharge, overdischarge and overcurrent.
Features
(1) Internal high accuracy voltage detection circuit
• Overcharge detection voltage
3.9 V to 4.5 V (applicable in 5 mV step) Accuracy: ±25 mV (+25°C) and
±30 mV (−5°C to +55°C)
• Overcharge hysteresis voltage
0.1 V to 0.4 V*1
Accuracy: ±25 mV
The overcharge hysteresis voltage can be selected from the range 0.1 V to 0.4 V in 50 mV step.
