XC6240A2637R-G

XC6240A2637R-G is a XC6240 series charging IC for rechargeable batteries compatible with CV charging. This product consists of regulators which have achieved an ultra-low supply current of 0.8uA. The output voltage of this product is internally fixed to be compatible with the CV voltages of rechargeable battery. Even if fluctuations are taken into account, the CV voltages of rechargeable batteries will not be exceeded, so charging can be performed without concern. The addition of a diode on the input side also allows the sink current flowing from a rechargeable battery to the regulator to be suppressed to 0.24uA, which can greatly contribute to extending the battery-driven time while charging is not being performed. The CE function can turn the regulator output off and put the IC into a shutdown state where the supply current can be substantially reduced. Application includes rechargeable batteries compatible with CV charging, IoT devices and smart cards.
