FEATURES
(1) High-accuracy voltage detection for each cell●
● Overcharge detection voltage n (n = 1 to 3) 3.9 V to 4.4 V (50 mV steps) Accuracy ±25 mV *1 Accuracy ±50 mV Overcharge release voltage n (n = 1 to 3) 3.8 V to 4.4 V *1. Overcharge release voltage = Overcharge detection voltage − Overcharge hysteresis voltage (Overcharge hysteresis voltage n (n = 1 to 3) can be selected as 0 V or from a range of 0.1 V to 0.4 V in 50 mV steps.)
●
● Overdischarge detection voltage n (n = 1 to 3) 2.0 V to 3.0 V (100 mV steps) *2 Accuracy ±80 mV Overdischarge release voltage n (n = 1 to 3) 2.0 V to 3.4 V Accuracy ±100 mV *2. Overdischarge release voltage = Overdischarge release voltage − Overdischarge hysteresis voltage (Overdischarge hysteresis voltage n (n = 1 to 3) can be selected as 0 V or from a range of 0.2 V to 0.7 V in 100 mV steps.) (2) Three-level overcurrent detection (including load short circuiting detection)
● Overcurrent detection voltage 1 0.05 V to 0.30 V (50 mV steps) Accuracy...
