BATTERY PROTECTION IC
FOR 2-SERIAL-CELL PACK
Rev.2.3
_01
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)
3.9 V to 4.5 V (50 mV steps)
Accuracy
±25
mV
*1
Accuracy
±50
mV
Overcharge release voltage n (n
=
1, 2)
3.8 V to 4.5 V
Overdischarge detection voltage n (n
=
1, 2)
2.0 V to 3.0 V (100 mV steps)
Accuracy
±50
mV
*2
Accuracy
±100
mV
Overdischarge release voltage n (n
=
1, 2)
2.0 V to 3.4 V
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
Delay times (overcharge, overdischarge, overcurrent) are generated by an internal circuit (external capacitors are
unnecessary).
0 V battery charge function available/unavailable are selectable.
Charger detection function
The overdischarge hysteresis is released by detecting negative voltage at the VM pin (−0.7 V typ.) (Charger
detection function).
High-withstand voltage devices
Absolute maximum rating: 28 V
Wide operating temperature range
−40°C
to
+85°C
Low current consumption
Operation mode
