R5437L Series 1 to 3 Cells Li-Ion Battery Protection IC for Secondary Protection No. EA-416-210518 OUTLINE The R5437L 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.
