UMW R AP5056 Description AP5056H is a complete single-chip lithium-ion battery constant current/constant voltage linear power management chip. Its MSOP-8/SOP-8 package and minimal peripheral components are very suitable for portable products, and AP5056H is specifically designed for USB power supply specifications. Based on the internal MOSFET structure, there is no need for external sensing resistors and isolation diodes. When the external ambient temperature is too high or working at high power, thermal feedback can adjust the charging current to reduce the chip temperature. The charging voltage is fixed at 4.2V, and the charging current can be set through an external resistor.
