Voltage transition control for USB power delivery sources

Abstract:

A circuit includes a controller to communicate with a sink device and communicate a plurality of power sources that are available to the sink device. A plurality of switch devices switch power from one of the plurality of power sources to the sink device in response to a control signal from the controller. A policy engine in the controller defines policies for the operation of the controller during different communications phases between the controller and the sink device.
