Abstract
A single-interface charging-discharging switchable circuit comprising a power management unit U, field effect transistors Q˜Q, capacitors C˜C, resistors R˜R, a diode Dand an inductor L. The product fills the gap in the market where there is no automatic charging-discharging switching circuit with the same interface, which enables the same interface (VCC/GND) to realize discharging and charging functions. The circuit of the disclosure is simple and has broad application prospects. The product of the disclosure uses a 5V-30V power supply to charge, and mobile phone adapters, portable power supply and other 5V power supply can be used as chargers. It is not limited by the 5V voltage of the traditional power supply, and the range of the input voltage of charging is wide.
