Nisshinbo R5642L Overcharge Protection ICs
Nisshinbo R5642L Overcharge Protection ICs are for 1 to 3 serial cells Li-ion/Li-polymer rechargeable battery. The IC provides the high-accuracy voltage detection function and the shutdown function. This can reduce the supply current to the minimum when all cell's voltage becomes less than the shutdown detection voltage.
