单芯片三合一移动电源充放电芯片常开5V自动负载启动状态灯CXLB74146 is a switching Li-Ion battery charger capable of delivering up to 1.2A of charging current to the battery and also capable of delivering up to 5V/1.2A in boost

   产品概述 返回TOPk8Q嘉泰姆

      CXLB74146 is a switching Li-Ion battery charger capable of delivering up to 1.2A of charging current to the battery and also capable of delivering up to 5V/1.2A 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. CXLB74146is an ideal all-in-one solutionfor 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. CXLB74146 is suitable for charging a 4.2V Li-ion battery. And CXLB74146is inESOP8 package
