     CXLB74149 is a switching Li-Ion battery charger capable of delivering 2A of charging current to the battery and also capable of delivering up to 5V/2.4A in boost operation, with high efficiency in both charging mode and boost mode. It also includes a fuel gauge system for power indication. For charging, it uses a proprietary control scheme that eliminates the current sense resistor for conventional constant current control, maximizing efficiency, reducing charging time and reducing costs. It can also output a 5V voltage in the reversed direction by boosting from the battery. It only needs a single inductor to provide power bidirectionally with a proprietary automatic mode detect and switch scheme. CXLB74149 is an ideal all-in-one solution for battery charging and discharge applications, such as power banks, smart phones, and tablets with only one USB port that can be used for charging battery function. CXLB74149 is suitable for charging a 4.2V Li-ion battery. And CXLB74149is inESOP8 package.
