ELECTRONIC DEVICE AND METHOD FOR CONTROLLING POWER SUPPLY OF ELECTRONIC DEVICE - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18346540 Titled 'ELECTRONIC DEVICE AND METHOD FOR CONTROLLING POWER SUPPLY OF ELECTRONIC DEVICE'
Simplified Explanation
This abstract describes an electronic device that has a USB interface for communication with an external device, a power management IC for controlling power, and a processor that connects to both the USB interface and the power management IC. The processor is programmed to send a command to the external device to request unique identification information when it is connected via the USB interface. Based on the received identification information, the processor recognizes the external device as a power supply device if it is capable of supplying power to the electronic device. Additionally, the processor can send a command to reboot the external device via the USB interface if the electronic device is powered off and has a battery, but it will not send the command if the electronic device does not have a battery.
Original Abstract Submitted
An electronic device according to various embodiments comprises: a universal serial bus (USB) interface for configuration channel (CC) communication with an external device; a power management IC (PMIC) for power control of the electronic device; and a processor operatively connected to the USB interface and the PMIC. The processor is configured to: control to transmit a first command, requesting unique identification information, to the external device via the USB interface based on the external device being connected via the USB interface; recognize the external device as a power supply device, for supplying power to the electronic device, on the basis of the unique identification information received from the external device; and control to transmit a second command, instructing rebooting of the external device, via the USB interface based on the electronic device including a battery and being powered off, and not transmit the second command to the external device based on the electronic device not including a battery and being powered off.
