AP5056
Description
AP5056H is a plete single-chip lithium-ion battery constant current/constant voltage linear power management chip. Its MSOP-8/SOP-8 package and minimal peripheral ponents 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. When the charging current drops to 1/10 of the set value after reaching the final float voltage, AP5056H will automatically terminate the charging cycle. When the input terminal (adapter or USB power supply) is unplugged, AP5056H automatically enters a low current state, and the battery leakage current will drop below 0.5 μ A....
