Cxch76021 cxch76022 is specially designed for large capacity lithium-ion battery or lithium polymer battery. It is a universal charging IC that can automatically identify the polarity of the battery and has the function of current limiting and constant voltage. The chip adopts dip-8 and cob-8 package. The application circuit of the chip is simple, and there are few peripheral devices, so it is suitable for portable application. The cxch76021 cxch76022 has a built-in automatic polarity discrimination circuit, which can automatically identify the polarity of the battery and correctly charge the battery. The preset saturation voltage is 4.22v. When the charging voltage is almost reached, the charging current will drop to 80mA; when the charging voltage is reached, the cxch76021 cxch76022 will automatically stop charging. Cxch76021 cxch76022 has four LED indicator pins, which can provide a variety of application schemes. Users can choose the corresponding indicator mode according to the actual needs
