USB Type-C and Power Delivery
1.1
Overview
The USB Type-
C™ and Power Delivery technologies simplify development and enhance
user experience; the new reversible USB Type-C connector insertion is more intelligent and
user friendly.
These technologies offer a smart connector able to carry all the necessary data (including
video) as well as negotiate up to 100 W supply or charge connected equipment according
to the Power Delivery protocol.
Less cables, less connectors and universal chargers are among the final objectives.
The USB Type-C connector supports up to 15 W (5 V at 3 A), which rises to 100 W (up to
20 V at 5 A) adopting the USB Power Delivery feature.

Main characteristics
The USB Implementer Forum (USB-IF) introduces these complementary specifications:
1.
the USB Type-
C™ receptacle, plug and cable specification rev. 1.2
2.
the USB Power Delivery (PD) specification rev. 2.0 that allows two PD compliant
entities to exchange up to 100 W during their negotiations.
Any system embedding a USB Type-C receptacle or plug which is designed to implement a
USB Power Delivery application such as a single port device, a multi-port hub or a simple
cable is based on these specifications.
The connector is intended for a wide range of charging applications like computers,
displays and mobile phones, with all the advanced features of PD:
power role negotiation
power sourcing and consumption level negotiation
electronically marked cable identification
vendor-specific message exchange
alternate-mode negotiation, allowing different communication protocols to be routed
onto the reconfigurable pins of the USB Type-C connectors.
The cables use the same male connector on both ends.
