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 0.4 V in 50 mV steps.) *2. Overdischarge release voltage = Overdischarge detection voltage + Overdischarge hysteresis voltage (Overdischarge hysteresis voltage n (n = 1, 2) can be selected as 0 V or from a range of 0.1 V to 0.7 V in 100 mV steps.) (2) 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 d...
