BATTERY PROTECTION IC
FOR 1-CELL PACK
The S-8211E Series has high-accuracy voltage detections circuit and delay circuits.
The S-8211E Series is suitable for monitoring overcharge and overdischarge of 1-cell lithium ion / lithium polymer
rechargeable battery pack.
(1) High-accuracy voltage detection circuit
Overcharge detection voltage
3.6 V to 4.5 V (5 mV step)
Accuracy 25 mV (25C)
Overcharge release voltage
3.5 V to 4.4 V*1
Accuracy 30 mV (5C to 55C)
Accuracy 50 mV
Overdischarge detection voltage
Overdischarge release voltage
2.0 V to 3.0 V (10 mV step)
2.0 V to 3.4 V*2
Accuracy 50 mV
Accuracy 100 mV
(2) Detection delay times are generated by an internal circuit
(external capacitors are unnecessary)
(3) Wide operating temperature range
40C to 85C
(4) Low current consumption
3.0 A typ., 5.5 A max. (25C)
2.0 A typ., 3.5 A max. (25C)
(5) Output logic of CO pin is selectable.
(6) Lead-free, Sn 100%, halogen-free*3
Active “H”, Active “L”
*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.)
*3. Refer to “ Product Name Structure” for details.
