USB Type-C & power delivery – Getting started
What is USB Type-C™?
USB Type-C is the latest USB standard. It enables reversible plug orientation and cable direction while leveraging small form-factor connectors. Power capabilities have been extended up to 15 W which lets the source dynamically manage current from 0.5 A to 3 A. Data speeds have been increased to 10 Gbps. Beyond that, USB Power Delivery support enables negotiable power up to 100 W. Additional capabilities such as the DisplayPort™ Alternate Mode and backward compatibility bring USB Type-C to the next level

What is USB Power Delivery?
USB Power Delivery (PD) is a single-wire protocol leveraging new USB Type-C standards and cables. With USB PD, USB Type-C ports can be either a source, sink or both. USB PD negotiation lets devices create a contract to deliver the optimum power level for each application. This protocol expands USB to deliver up to 100 W (20 V, 5 A) of power. Data role capabilities are also enhanced as the USB PD protocol is used to negotiate data and video capabilities and direction. USB Type-C ports can be an upstream facing port (UFP) transmitting as a USB device, a downstream facing port (DFP) transmitting as a USB host, or a dual-role data port (DRD) having capabilities of both UFP and DFP. USB Alternate Mode enables guest protocols such as DisplayPort™ .
