  • USB charger, mobile terminal and charging method thereof
    Patent number: 9923396
    Abstract: A USB charger, a mobile terminal, and a charging method are provided. The USB charger for charging a mobile terminal, includes a first logic control unit through which bidirectional communication is established between the USB charger and the mobile terminal, wherein the first logic control unit is configured to: send, to the mobile terminal, a first signal which indicates a maximum output capability of the USB charger; receive, from the mobile terminal, a second signal which indicates magnitude of a voltage requested by the mobile terminal; adjust a voltage output from the USB charger to be consistent with the voltage requested by the mobile terminal; and transmit a clock signal between the mobile terminal. Accordingly, the USB charger and the mobile terminal can communicate through two single signal wires by way of pulse signals. Thus, the mobile terminal is charged in a fast, safe, and simply way.
