Cxlb7443b is a single-chip solution designed for mobile power supply, which integrates synchronous switch charging module, Synchronous Boost discharge management module, power detection

Cxlb7443b is a single-chip solution designed for mobile power supply, which integrates synchronous switch charging module, Synchronous Boost discharge management module, power detection and LED indicator module, and protection module. Cxlb7443b has built-in charging and discharging power MOS, the charging current can be set, the maximum charging current is 2.5A, and the synchronous boost output is 2.1a. The cxlb7443b adopts the patented charging current adaptive technology to adapt to the small current adapter, and adopts the patented control mode to save the external power setting resistance, reduce the power consumption and reduce the system cost. The cxlb7443b integrates multiple safety protection functions such as temperature compensation, over temperature protection, over charge and over discharge protection, output over-voltage protection, output over load protection, output short circuit protection, etc. to ensure the safety of chips and lithium-ion batteries. The application circuit is simple, and charging management and discharge management can be realized with few components.
