BM3103-TNDB

BM3103 Series Three-cell Battery Protectors wwwBM3103 Series IC is a high-precision, highly integrated dedicated 3-cell battery protection chip, suitable for power tools, .cvacuum cleaners and small back-up power. IC through the detection of each section of the battery voltage, discharge ttcurrent and ambient temperature and other information to achieve battery overcharge, over release, discharge gover-current, short-circuit, high-temperature protection functions, through the external capacitor to adjust the overcharge, .cover release, discharge overcurrent protection delay. w omFeatures w .h High-accuracy voltage detection for each cell w k Overcharge threshold 3.6 V ~ 4.6 V .c Overcharge hysteresis 0.12 V tt Over-discharge threshold 1.6 V ~ 3.0 V g Over-discharge hysteresis 0.2 / 0.4 V .c Three grades voltage detection of discharge overcurrent o Discharge overcurrent 1 0.050 V ~ 0.150 V (25 mV step) m Discharge overcurrent 2 0.1 / 0.2 / 0.3 / 0.4 ...
