BATTERY PROTECTION IC
FOR 1-CELL PACK
Rev.2.4_03
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.
Features
(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)
Accuracy 20%
(3) Wide operating temperature range
40C to 85C
(4) Low current consumption
During operation
3.0 A typ., 5.5 A max. (25C)
During overdischarge
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.
