OUTLINE
The R5438L is an overcharge protection IC for 1 to 3 serial cells Li-ion / Li-polymer rechargeable battery.
This device provides the high-accuracy
voltage detection function and the shutdown function can reduce the supply current to the minimum when all cell’s
voltage becomes less than the shutdown detection
voltage.
