  • Publication number: 20140365806
    Abstract: A peripheral apparatus and a control method thereof are provided. The peripheral apparatus is suitable for coupling an electronic device to provide a peripheral function to the electronic device for use, where the peripheral apparatus draws power supplies from the electronic device. The peripheral apparatus includes a power detecting module and a control unit. The power detecting module detects a voltage drop characteristic of a system voltage provided by the electronic device and generates a voltage detecting signal accordingly, where the voltage detecting signal is related to a magnitude of an average output current of the electronic device. The control unit is coupled to the power detecting module and controls an operation state of the peripheral apparatus according to the voltage detecting signal, such that the peripheral apparatus is operated in at least one of a first, a second and a third operation states which are different from each other.
