  • USB machine
    Publication number: 20020050936
    Abstract: A self-powered USB machine. A power control switch 23 is installed in a main power circuit 21 of the USB machine. By detecting whether a voltage occurs at a +5V power terminal of a USB port, the power control switch 23 is turned on or off. A pull-up resistor 17 is connected to a switch 18 in series. And, the pull-up switch 18 is turned on or off after the power control switch 23 is turned on or off. Thereby, the power consumption is reduced.
