S-8242 Overview
Rev.1.0_00 BATTERY PROTECTION IC FOR 2-SERIAL-CELL PACK S-8242 Series The S-8242 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-8242 Key Features
- 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
- (3) (4) (5) Overcurrent detection voltage 1 0.05 V to 0.30 V (50 mV steps) Accuracy ±15 mV
- Overcurrent detection voltage 2 1.2 V (fixed) Accuracy ±300 mV Delay times (overcharge, overdischarge, overcurrent) are
- The overdischarge hysteresis is released by detecting negative voltage at the VM pin (-0.7 V typ.). (Charger detection f
