BATTERY PROTECTION IC
FOR 2-SERIAL-CELL PACK
Rev.1.0_03
S-8262A Series is a protection IC for 2-serial-cell lithium-ion / lithium polymer rechargeable batteries and includes high-
accuracy voltage detectors and delay circuits.
The S-8262A Series has an alarm signal output pin (AO pin) which outputs the alarm detection signal.
The alarm detection signal is output prior to the charge control FET signal by overcharge detection.
Features
High-accuracy voltage detection for each cell
Overcharge detection voltage n (n = 1, 2) 3.900 V to 4.500 V (5 mV steps) Accuracy 20 mV (Ta = 25°C)
Overcharge release voltage n (n = 1, 2)
3.800 V to 4.500 V*1
Accuracy 25 mV (Ta = 10°C to 60°C)
Accuracy 30 mV
Overdischarge detection voltage n (n = 1, 2) 2.000 V to 3.000 V (10 mV steps) Accuracy 50 mV
Overdischarge release voltage n (n = 1, 2) 2.000 V to 3.400 V*2
Accuracy 100 mV
Discharge overcurrent 1 detection voltage 0.050 V to 0.200 V (10 mV steps) Accuracy 10 mV
Discharge overcurrent 2 detection voltage 0.200 V to 0.400 V (20 mV steps) Accuracy 20 mV
Load short-circuiting detection voltage
0.700 V (fixed)
Accuracy 100 mV
Charge overcurrent detection voltage
0.400 V to 0.050 V (25 mV steps) Accuracy 20 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.
Wide operating temperature range
Ta = 40°C to 85°C
Low current consumption
During operation
8.0 A max. (Ta = 25°C)
During power-down
0.1 A max. (Ta = 25°C)
Lead-free (Sn 100%), halogen-free
*1. Overcharge release voltage = Overcharge detection voltage Overcharge hysteresis voltage
(Overcharge hysteresis voltage n (n = 1, 2) can be selected as 0 V or from a range of 0.1 V to 0.4 V in 25 mV
steps.)
*2. Overdischarge release voltage = Overdischarge detection voltage Overdischarge hysteresis voltage
(Overdischarge hysteresis voltage n (n = 1, 2) can be selected as 0 V or from a range of 0.1 V to 0.7 V in 100 mV
steps.)
