Abstract

The invention provides USB-C equipment and an electronic device, and the USB-C equipment comprises a UFP unit which comprises a first configuration channel; a to-be-tested unit which comprises a second configuration channel; a switch unit electrically connected with the first configuration channel and the second configuration channel, wherein the connection between the first configuration channeland the second configuration channel is controlled by controlling the conduction of the switch unit; the disconnection of the first configuration channel and the second configuration channel is controlled by controlling the cut-off of the switch unit. According to the scheme, the switch-on and switch-off of the switch unit can be controlled according to actual requirements; under the condition that the first configuration channel of the UFP unit is out of power, the switch unit is controlled to be cut off so as to control the first configuration channel and the second configuration channel notto be connected, and due to the fact that the first configuration channel and the second configuration channel are not connected, normal detection of the configuration channel of the to-be-detected unit cannot be affected even if a pull-down resistor exists.

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 ...
