IEC 62680 Part 1-2 Released for USB Power Delivery

The International Electrotechnical Commission (IEC) has released a new edition of the standard for “Universal serial bus interfaces for data and power – Part 1-2: Common components – USB Power Delivery specification.” IEC 62680-1-2:2016 can be purchased at the IEC webstore.

Description: “IEC 62680-1-2:2016(E) defines a power delivery system covering all elements of a USB system including: Hosts, Devices, Hubs, Chargers and cable assemblies. This specification describes the architecture, protocols, power supply behavior, connectors and cabling necessary for managing power delivery over USB at up to 100W.

This specification is intended to be fully compatible and extend the existing USB infrastructure. It is intended that this specification will allow system OEMs, power supply and peripheral developers adequate flexibility for product versatility and market differentiation without losing backwards compatibility. USB Power Delivery is designed to operate independently of the existing USB bus defined mechanisms used to negotiate power.
