Abstract
An interface control circuit to apply a compatible voltage for a USB device upon connection includes a USB connector, a controlling module, and a switching module. The USB connector outputs the plug signal when connected to the USB device. The controlling module outputs a power supply signal when the plug signal is received. The switching module outputs a power supply drive signal when the power supply signal is received.
