A new and improved separable loadbreak connector system capable of providing higher switching and fault close ratings by various means of dividing the arc energy within the connector system.

An electronic device having a universal serial bus (USB) power delivery function includes a connector, an electrostatic discharge (ESD) protection circuit, a power reception notification circuit, and a control circuit. The connector is coupled to a USB host. The connector includes a configuration channel (CC) pin. The power reception notification circuit is configured to turn on, in response to an enable signal, a pull-down path of a pull-down circuit of the ESD protection circuit. The configuration channel pin generates a pull-down voltage through the pull-down path of the pull-down circuit when the pull-down path is turned on. The control circuit is configured to send the enable signal to the power reception notification circuit when a trigger signal that meets a power reception condition is detected. The control circuit controls the connector to draw power from the USB host when the pull-down voltage of the connector is greater than a pull-down threshold.
