S-8242B Overview
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.
S-8242B Key Features
- 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
- 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)
- The overdischarge hysteresis is released by detecting negative voltage at the VM pin (-0.7 V typ.) (Charger detection fu
