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.

Features

Low consumption current
Low shutdown current

Longer driving time with a battery of small capacity
