Abstract:
A bridging device and a power saving method thereof are disclosed. The disclosed bridging device includes a connector, a connection detector and a bridging chip. The connector is operative to connect to a host and includes a power pin and a command pin. The connection detector is coupled to the power pin to determine whether the connector is floating, and, outputs a linked signal when the connection is non-floating. The bridging chip is coupled to the command pin and the connection detector. When the bridging chip receives a power saving command transferred from the host via the command pin and the linked signal transferred from the connection detector, the bridging chip executes a power saving operation.
Abstract:
An operating system including a voltage converter, a processing circuit, and a protector is provided. The voltage converter converts an input voltage according to a feedback voltage to generate an output voltage. The processing circuit is coupled to the voltage converter and processes the output voltage according to a control signal to generate the feedback voltage. The protector is coupled to the voltage converter and the processing circuit and activates or deactivates the voltage converter according to the feedback voltage.
