BATTERY PROTECTION IC
FOR 1-CELL PACK
Rev.6.5_03
The S-8211D Series is a protection IC for 1-cell lithium-ion / lithium-polymer rechargeable battery 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.
Features
High-accuracy voltage detection circuit
Overcharge detection voltage
3.6 V to 4.5 V (5 mV step)
Accuracy 25 mV (Ta = 25C)
Overcharge release voltage
3.5 V to 4.4 V*1
Accuracy 30 mV (Ta = 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
Discharge overcurrent detection voltage
0.05 V to 0.30 V (10 mV step) Accuracy 15 mV
Load short-circuiting detection voltage
0.5 V (fixed)
Accuracy 200 mV
Detection delay times are generated only by an internal circuit (external capacitors are unnecessary).
Accuracy 20%
High-withstand voltage (VM pin and CO pin: Absolute maximum rating = 28 V)
0 V battery charge function "available" / "unavailable" is selectable.
Power-down function "available" / "unavailable" is selectable.
Wide operation temperature range
Ta = 40C to 85C
Low current consumption
During operation
3.0 A typ., 5.5 A max. (Ta = 25C)
During power-down
Lead-free, Sn 100%, halogen-free*3
0.2 A max. (Ta = 25C)
*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.
