BM3451 Description
The BM3451 is a professional protection IC for 3/4/5 cells rechargeable battery pack; it is highly integrated, and generally used in power tools, electric bicycles and UPS applications. The BM3451 works constantly to monitor each cell’s voltage, the current of charge or discharge, and the temperature of the environment to provide overcharge, over-discharge, discharge overcurrent, short circuit, charge overcurrent...
