Description

This is BATTERY PROTECTION IC. Rev.2.3_00 BATTERY PROTECTION IC FOR 3-SERIAL OR 4-SERIAL-CELL PACK S-8254 Series The S-8254 series is a protection IC for 3-serial or 4-serial cell lithium ion rechargeable batteries and includes a high-accuracy voltage detector and delay circuit. The S-8254 series protects both 3-serial or 4-serial cells using the SEL pin for switching. Features (1) High-accuracy voltage detection for each cell Overcharge detection voltage n (n = 1 to 4) 3.9 V to 4.4 V (50 mV steps) Accuracy ±25 mV *1 Accuracy ±50 mV Overcharge release voltage n (n = 1 to 4) 3.8 V to 4.4 V *1. Overcharge hysteresis voltage n (n = 1 to 4) can be selected as 0 V or from a range of 0.1 V to 0.4 V in 50 mV steps. (Overcharge hysteresis voltage = Overcharge detection voltage Overcharge release voltage) Overdischarge detection voltage n (n = 1 to 4) 2.0 V to 3.0 V (100 mV steps) *2 Accuracy ±80 mV Overdischarge release voltage n (n = 1 to 4) 2.0 V to 3.4 V Accuracy ±100 mV *2.
