com BATTERY PROTECTION IC FOR 2-SERIAL-CELL PACK S-8242B Series 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 rechargeable lithium-ion / lithium polymer battery packs from overcharge, overdischarge, and overcurrent.
„ Features 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 • Overcharge release voltage n (n = 1, 2) 3.
8 V to 4.
5 V*1 Accuracy ±50 mV • 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 *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 ...
