Description
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.
