The R5640 is an overcharge protection IC for 2- to 5- serial cell Li-ion / Li-polymer rechargeable battery pack, with built-in high-accuracy voltage detection circuits and delay circuits. Controlling the supply voltage to the CTLC pin can control the COUT pin output. The shutdown detection can reduce the supply current to the minimum.
