BATTERY PROTECTION IC FOR 1-CELL PACK
Rev.5.4_03
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 3.900 V to 4.500 V (applicable in 5 mV step) Accuracy: 25 mV (25C) and
Overcharge hysteresis voltage 0.1 V to 0.4 V*1
30 mV (5C to 55C)
Accuracy: 25 mV
The overcharge hysteresis voltage can be selected from the range 0.1 V to 0.4 V in 50 mV step.
Overdischarge detection voltage 2.000 V to 3.000 V (applicable in 10 mV step) Accuracy: 50 mV
Overdischarge hysteresis voltage 0.0 V to 0.7 V*2
Accuracy: 50 mV
The overdischarge hysteresis voltage can be selected from the range 0.0 V to 0.7 V in 100 mV step.
Overcurrent 1 detection voltage
0.050 V to 0.300 V (applicable in 10 mV step) Accuracy: 15 mV
Overcurrent 2 detection voltage 0.500 V (fixed)
Accuracy: 100 mV
(2) High-withstand voltage (VM pin and CO pin: Absolute maximum rating 28 V)
(3) Delay times (overcharge: tCU, overdischarge: tDL, overcurrent 1: tlOV1, overcurrent 2: tlOV2) are generated by an
internal circuit. No external capacitor is necessary.
Accuracy: 20%
(4) Three-step overcurrent detection circuit is included (overcurrent 1, overcurrent 2 and load short-circuiting).
(5) 0 V battery charge function “Available” / “Unavailable” is selectable.
(6) Power-down function “Yes” / “No” is selectable.
(7) Charger detection function and abnormal charge current detection function
The overdischarge hysteresis is released by detecting negative voltage at the VM pin (0.7 V typ.) (Charger
detection function).
When the output voltage of the DO pin is high and the voltage at the VM pin is equal to or lower than the charger
detection voltage (0.7 V typ.), the output voltage of the CO pin goes low (Abnormal charge current detection
function).
(8) Low current consumption
Operation mode
3.5 A typ., 7.0 A max.
Power-down mode 0.1 A max.
(9) Wide operating temperature range 40C to 85C
(10) Lead-free, Sn 100%, halogen-free*3
