The S-8211E Series has the high-accuracy voltage detection circuit and the delay circuit. This IC is suitable for monitoring overcharge and overdischarge of 1-cell lithium ion / lithium polymer secondary battery pack.

Features

High-accuracy voltage detection circuit: Overcharge detection voltage 3.6 V to 4.5 V (5 mV step) Accuracy ±25 mV (+25°C) / Accuracy ±30 mV (-5°C to +55°C; Overcharge release voltage 3.5 V to 4.4 V^*1 Accuracy ±50 mV; Overdischarge detection voltage 2.0 V to 3.0 V (10 mV step) Accuracy ±50 mV; Overdischarge release voltage 2.0 V to 3.4 V^*2 Accuracy ±100 mV
Detection delay times are generated by an internal circuit (external capacitors are unnecessary) Accuracy ±20%
Wide operating temperature range: -40°C to +85°C
Low current consumption: Operation mode 3.0 µA typ., 5.5 µA max. (+25°C); Overdischarge mode 2.0 µA typ., 3.5 µA max. (+25°C)
Lead-free, Sn 100%, halogen-free

*1. Overcharge release voltage = Overcharge detection voltage – Overcharge hysteresis voltage (Overcharge hysteresis voltage can be selected as 0 V or from a range of 0.1 V to 0.4 V in 50 mV step.)

*2. Overdischarge release voltage = Overdischarge detection voltage + Overdischarge hysteresis voltage (Overdischarge hysteresis voltage can be selected as 0 V or from a range of 0.1 V to 0.7 V in 100 mV step.)

Applications

Lithium-ion rechargeable battery packs
Lithium-polymer rechargeable battery packs
