Abstract

A control device and a related non-transitory storage device are provided, the control device includes: a first multiplexer coupled to a plurality of high-speed differential pair terminals; a second multiplexer coupled to a plurality of non-high-speed differential pairs To the terminal; set the circuit, receive the channel information signal and the power information signal from the external device, control the first multiplexer and the second multiplexer and generate the channel setting instruction according to the channel information signal, and generate the power setting instruction according to the power information signal; control The circuit controls the external power supply module according to the power setting command; the high-frequency oscillating circuit provides high-frequency frequency to the control circuit and the setting circuit; the power supply circuit provides multiple operating voltages to the first multiplexer, the second multiplexer, the control circuit and the high-frequency A frequency oscillation circuit; the control circuit controls the power supply circuit according to the channel setting instruction and the power setting instruction, so as to set the first multiplexer, the second multiplexer or the high frequency oscillation circuit in a disabled state. The control device can regulate its own power consumption.

Description

technical field [0001] The present application relates to a control device suitable for a universal serial bus (USB). Background technique [0002] Thinner and lighter products are the design trend of the mobile device industry today. However, the thinner and lighter design will also reduce the space allocated to the battery, thereby reducing the working time of the mobile device. Therefore, it is also one of the current design trends to install components with low power consumption in the mobile device to prolong the working time of the mobile device. However, no matter whether the current mobile device is connected to other devices through the USB interface or not, the traditional USB control device therein consumes the same power, thus considerably reducing the working time of the mobile device. Contents of the invention [0003] In view of this, how to provide a USB control device capable of adaptively adjusting power consumption and related computer application prod...
