POWER SAVING FOR HOT PLUG DETECT |
摘要 |
In a particular embodiment, an electronic device includes a direct current (DC) voltage source coupled to a DC interface. The electronic device includes a receiver sense circuit configured to detect a connection of the electronic device to a sink device via a connector without consuming power from the DC voltage source. The electronic device further includes a controller coupled to a hot plug detect (HPD) interface. The controller is configured to receive a detection signal from the receiver sense circuit, selectively control a switch to enable and disable the DC voltage source based on the detection signal, detect an HPD signal at the HPD interface after enabling the DC voltage source, and disable the receiver sense circuit in response to detecting the HPD signal. |
