Cxlb73155 is a perfect single-chip lithium-ion battery constant current/constant voltage linear power management chip small outer packaging make it suitable for portable applications

Cxlb73155 is a perfect single-chip lithium-ion battery constant current / constant voltage linear power management chip. Its thin size and small outer packaging make it suitable for portable applications. What's more, cxlb73155 is specially designed for USB power supply. Due to the internal MOSFET structure, external resistors and blocking diodes are not needed in application. The charging voltage is limited to 4.2V, and the charging current is regulated by external resistance. After the target charging voltage is reached, when the charging current drops to 1 / 10 of the set value, the cxlb73155 will automatically end the charging process. When the input terminal (plug or USB power supply) is unplugged, the cxlb73155 will automatically enter the low current state, and the battery leakage current will drop below 1 μ a. The cxlb73155 can also be set to stop working to reduce the power supply current to 40 μ a. The unique internal patent structure of cxlb73155 ensures that the chip will automatically enter the protection state when the battery is connected reversely, and ensures that the IC will not be broken down, leading to battery self discharge accidents. At the same time, ensure that the ESD capacity of cxlb73155 reaches 6kV (HBM).
