BATTERY PROTECTION IC
FOR 2-SERIAL-CELL PACK
Rev.2.3_02
The S-8242B Series are protection ICs for 2-serial-cell lithium-ion/lithium polymer rechargeable batteries and include high-
accuracy voltage detectors and delay circuits.
These ICs are suitable for protecting 2-cell lithium-ion / lithium polymer rechargeable battery packs from overcharge,
overdischarge, and overcurrent.
Features
(1) High-accuracy voltage detection for each cell
Overcharge detection voltage n (n 1, 2)
Overcharge release voltage n (n 1, 2)
3.9 V to 4.5 V (50 mV steps)
3.8 V to 4.5 V*1
Accuracy 25 mV
Accuracy 50 mV
Overdischarge detection voltage n (n 1, 2)
Overdischarge release voltage n (n 1, 2)
2.0 V to 3.0 V (100 mV steps)
2.0 V to 3.4 V*2
Accuracy 50 mV
Accuracy 100 mV
(2) Two-level overcurrent detection (overcurrent 1, overcurrent 2)
Overcurrent detection voltage 1
0.05 V, 0.08 V to 0.30 V (10 mV steps)
Accuracy 15 mV
Overcurrent detection voltage 2
1.2 V (fixed)
Accuracy 300 mV
(3) Delay times (overcharge, overdischarge, overcurrent) are generated by an internal circuit (external capacitors are
unnecessary).
(4) 0 V battery charge function available/unavailable are selectable.
(5) Charger detection function
The overdischarge hysteresis is released by detecting negative voltage at the VM pin (0.7 V typ.) (Charger
detection function).
(6) High-withstand voltage devices
Absolute maximum rating: 28 V
(7) Wide operating temperature range
40°C to 85C
(8) Low current consumption
Operation mode
10 A max. (25C)
Power-down mode
(9) Lead-free, Sn 100%, halogen-free*3
0.1 A max. (25C)
*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 50 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.)
*3. Refer to “Product Name Structure” for details.
Applications
