  • Patent number: 11842201
    Abstract: A portable electronic device includes a main system circuit, a storage, a power button, a power-off trigger circuit, a system power-off circuit, a power supply circuit, and a configuration power-off circuit. The power-off trigger circuit is coupled to the power button and provides a system power-off signal and a configuration power-off signal when the power button is detected to be continuously pressed and a pressing time is greater than a predetermined time. The system power-off circuit is coupled to the power-off trigger circuit and the power supply circuit and stops providing the main system circuit with a system power supply voltage provided by the power supply voltage according to the system power-off signal. The configuration power-off circuit is coupled to the power-off trigger circuit and the storage and drives the configuration power supply voltage provided to the storage down to a ground voltage according to the configuration power-off signal.

  • Patent number: 10956350
    Abstract: The application discloses an electronic device with a USB Type-C connector, which is able to be coupled to another electronic device. The electronic device includes a control unit, a switch unit and a charge conversion unit. The control unit outputs a first control signal according to a result of power supply handshaking between the electronic device and the other electronic device. The state of the first control signal determines whether the other electronic device supplies power to the electronic device. The switch unit is coupled to the control unit, and receives a supply voltage output by the other electronic device, and the switch unit determines whether to output the supply voltage according to the state of the first control signal. The charge conversion unit is coupled to the switch unit. The charge conversion unit converts the supply voltage into a target voltage to supply power to the electronic device.
