General Description
The BM3452 is a professional protection IC for 3 cells rechargeable battery pack; it is highly integrated,
and generally used in power tools, electric bicycles and UPS applications.
The BM3452 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 and over-temperature protections, etc. Besides, it also can change the
protection delay time of overcharge, over-discharge and discharge overcurrent by setting the external
capacitors.
