This International Standard defines interoperability guidelines for external power supplies used with portable computing devices that implement the IEC 62680-1-2: Universal Serial Bus Power Delivery Specification with the IEC 62680-1-3: Universal Serial Bus Interfaces for data and power-Common Components- Type-CTM Type-C Cable and Connector Specification.
This International Standard defines normative requirements for an EPS to ensure interoperability, in particular it specifies the data communicated from an EPS to a portable computing device (Figure 1). The scope does not apply to all aspects of an EPS. This International Standard does not specify normative requirements for the portable computing device but provides recommendations for the behaviour of a portable computing device when used with an EPS compliant with this International Standard.
This International Standard specifies the data objects used by a portable computing system using IEC 62680-1-2 to understand the identity, design and performance characteristics, and operating status of an external power supply.
This International Standard is applicable to external power supplies under 100 watts for portable computing devices, with a focus on power delivery application for notebook computers, tablets, smartphones and other related multimedia devices. This International Standard relies on established mechanical and electrical specifications, and communication protocols established by IEC 62680-1-2 and IEC 62680-1-3. This International Standard proposes methods supported by IEC 62680-1-2 to mitigate problems caused by the connection of untested combinations of EPS and portable computing devices with the aim of improving consumer satisfaction.
In addition, as given in Annex C, this International Standard provides interoperability guidelines for an EPS supporting charging using USB Type-C current when IEC 62680-1-2 functionality is not enabled. Considerations for captive and removable cable are presented in Annex B.
An EPS is expected to follow the applicable global standards and regulatory compliance requirements. Examples of those standards are given in Annex F.
