Abstract
A power device includes a power switch circuit, a driver, a regulator, at least one power obtaining circuit, a first pin, a second pin and a third pin. The driver controls the power switch circuit to connect the first pin to the second pin or disconnect the first pin from the second pin according to signals on the third pin. The at least one power obtaining circuit obtains voltages from the first pin, the third pin, and/or the power switch circuit. The regulator converts the voltages provided by the at least one power obtaining circuit into a suitable voltage and provides the suitable voltage for the power terminal of the driver. Since the power required for the driver can be obtained from inside the power device, there is no need to add an additional pin to obtain power from outside the power device.
