Universal serial bus interfaces for data and power - Part 1-2: Common components - USB Power Delivery specification
IEC 62680-1-2:2021 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.
This fifth edition cancels and replaces the fourth edition published in 2019 and constitutes a technical revision.
It is also identified as USB Power Delivery Specification, Revision 3.0, Version 2.0
This updated release of the USB PD specification was made to incorporate all the ECNs that were made to USB PD 3.0, V1.2. This makes a full completed printed specifications with all ECNs incorporated into a hard copy specification.
Interfaces de bus universel en série pour les données et l'alimentation électrique - Partie 1-2: Composants communs - Spécification de l'alimentation électrique par port USB
IEC 62680-1-2:2021 définit un système d'alimentation électrique par port USB qui couvre tous les éléments d'un système USB, y compris: hôtes, dispositifs, hubs, chargeurs et assemblages de câbles. La présente spécification décrit l'architecture, les protocoles, le comportement de l'alimentation électrique, les connecteurs et le câblage nécessaires à la gestion de l'alimentation électrique sur USB jusqu'à 100W. Cette spécification est destinée à être entièrement compatible avec les infrastructures USB existantes et à en assurer une extension. Il est prévu que cette spécification offre aux OEM de systèmes, ainsi qu'aux développeurs d'alimentations électriques et de périphériques, une souplesse appropriée pour une polyvalence des produits et leur différenciation sur le marché, sans perdre en compatibilité ascendante.
IEC 62680-1-2:2021 annule et remplace la quatrième édition publiée en 2019, dont elle constitue une révision technique.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.

INTRODUCTION
The IEC 62680 series is based on a series of specifications that were originally developed by the USB
Implementers Forum (USB-IF). These specifications were submitted to the IEC under the auspices of
a special agreement between the IEC and the USB-IF.
This standard is the USB-IF publication Universal Serial Bus Power Delivery Specification Revision
3.0, Version 2.0.
The USB Implementers Forum, Inc.(USB-IF) is a non-profit corporation founded by the group of
companies that developed the Universal Serial Bus specification. The USB-IF was formed to provide a
support organization and forum for the advancement and adoption of Universal Serial Bus technology.
The Forum facilitates the development of high-quality compatible USB peripherals (devices), and
promotes the benefits of USB and the quality of products that have passed compliance testing.
