Abstract:
A bridge is provided. The bridge is coupled between a host and a peripheral apparatus and includes a connector, a power circuit, and a bridge circuit. The connector connects the host and comprises a power pin. The power circuit converts a supplying power to a driving voltage when the power circuit is enabled. The bridge circuit is powered by the driving voltage and performs a data transmission procedure between the host and the peripheral apparatus. An enabling terminal of the power circuit is coupled to the power pin to receive an enabling signal transmitted by the host through the power pin. The power circuit is enabled to provide the driving voltage when the enabling signal is provided with a first potential. The power circuit is disabled to stop providing the driving voltage when the enabling signal is provided with a second potential.
