Abstract

The present application provides a USB‑C device and an electronic device, the USB‑C device includes a UFP unit, including a first configuration channel; a unit to be tested, including a second configuration channel; a switch unit, respectively connected to the first configuration channel and the second configuration channel The two configuration channels are electrically connected, the first configuration channel is controlled to be connected to the second configuration channel by controlling the conduction of the switch unit, and the first configuration channel is controlled not to be connected to the second configuration channel by controlling the cut-off of the switch unit. In fact, it is necessary to control the on and off of the switch unit. When the first configuration channel of the UFP unit is out of power, the control switch unit is turned off to control the disconnection between the first configuration channel and the second configuration channel. The second configuration channel is not connected, even if there is a pull-down resistor, it will not affect the normal detection of the configuration channel of the unit under test.

Description

technical field [0001] The present application relates to the technical field of interface connection detection, in particular, to a USB-C device and an electronic device. Background technique [0002] USB Type-C (referred to as USB-C) is a new USB product. The Type-C interface is a connection interface of the USB interface. It can be inserted regardless of the front and back sides. It supports USB standard charging, data transmission, Display output and other functions. [0003] At present, the Type-C interface includes an interface control chip to detect the insertion of external devices. The existing Type-C devices are divided into Upstream Facing Port (UFP for short) equipment and Downstream Facing Port (Downstream Facing Port, DFP for short) device, in order to monitor the message between DFP device and UFP device, it is often necessary to connect the configuration channel (Configuration Channel, CC for short) of the UFP device to the CC between the devices under test ...
