Title:
ELECTRONIC DEVICE COMPRISING CONNECTOR AND METHOD FOR SENSING DISCONNECTION
Document Type and Number:
WIPO Patent Application WO/2021/215707
Kind Code:
A1
Abstract:
Disclosed is an electronic device comprising: a housing; a USB connector formed on one side of the housing and connected to a USB plug of an external device; a high-speed interface for transmitting and/or receiving data to and/or from the external device connected to the USB connector; a voltage source for supplying a first voltage to the high-speed interface; a first circuit unit that is connected to a ground unit having a second voltage lower than the first voltage, and has a second impedance higher than a first impedance of the high-speed interface; and a processor. The processor is set to monitor the external device by using the high-speed interface in a first interval of a first frame, transmit and/or receive the data to and/or from the external device by using the high-speed interface in the first interval, form a disconnection sensing path by forming a connection, between the first circuit unit and a second circuit unit of the external device, in at least a portion of a second interval other than the first interval of the first frame, and use the disconnection sensing path to determine whether the connection between the USB connector and the USB plug has been disconnected, wherein the second circuit unit has a fourth impedance higher than a third impedance of an external high-speed interface of the external device. Various other embodiments as understood from the specification are also possible.
