Systems and methods for powering a charging circuit of a communications interface
First Claim
1. A method of powering a mobile device using a sink device, comprising:
- detecting a coupling of the mobile device to a communications receiver of the sink device;
transmitting an acknowledgement from the communications receiver in response to a query, the acknowledgement confirming that the sink device has charging capability;
receiving a power request to provide power to the mobile device; and
selectively providing power to the mobile device in response to the power request.

Abstract
Embodiments include systems and methods of powering a mobile device using a sink device. The method may include detecting a coupling of the mobile device to the sink device and transmitting an acknowledgement in response to a query, the acknowledgement confirming that the sink device has charging capability. Power may be selectively provided in response to the power request. According to some embodiments, the method includes transmitting a query by a communications transmitter to determine if a sink device has charging capability, and deactivating a driver for a power line and transmitting a power request using the communications transmitter in response to receiving an acknowledgement signal from the sink device. The method may further include selectively providing power received from the sink device to a charging circuit of the mobile device. The mobile device may include an HDMI transmitter for communicating through a transmission line to an HDMI sink device.
