Interoperability specifications and communication method for external power supplies used with computing and consumer electronics devices

This International Standard defines common charging interoperability guidelines for power sources (external power supplies (EPS) and other Sources) used with computing and consumer electronics devices that implement the IEC 62680-1-3: USB Type-C®1 Cable and Connector Specification. This document defines normative requirements for an EPS to ensure interoperability, in particular it specifies the data communicated from a power source to a device (Figure 1) and certain safety elements of the EPS, cable, and device. While the requirements focus of this document is on the EPS (External Power Supply) and the behavior at its USB Type-C connector interface, it is also important to comprehend cable assembly and device capabilities and behaviors in order to assure end-to-end charging interoperability. The scope does not apply to all design aspects of an EPS. An EPS compliant with this standard is also expected to follow other applicable global standards and regulatory compliance requirements for aspects such as product safety, EMC and energy efficiency. [Figure 1] This International Standard provides recommendations for the behavior of a device when used with a power source compliant with this document. This International Standard specifies the minimum hardware specification for an EPS implementing IEC 62680-1-3: USB Type-C. This document also specifies the data objects used by a charging system utilizing IEC 62680-1-2: USB Power Delivery Specification to understand the identity, design and performance characteristics, and operating status of an external power supply. IEC 62680-1-2 and IEC 62680-1-3 focus on power delivery applications ranging to 100W for a variety of computing and consumer electronic devices including notebook computers, tablets, smartphones, small form-factor desktops, monitor displays and other related multimedia devices. Future updates to IEC 62680-1-2 and IEC 62680-1-3 specifications will extend to enable power delivery applications that require more than 100W while remaining within the technical limitations of the USB Type-C cable and connector solution. This document relies on established mechanical and electrical specifications, and communication protocols specified by IEC 62680-1-2 and IEC 62680-1-3. These specifications support methods for establishing the best performing interoperability between untested combinations of EPS and devices with the aim of improving consumer satisfaction. Information describing the USB charging interoperability model, overview of USB Type-C and USB Power Delivery specifications, and factors for charging performance are also provided to support implementation of this standard.

156 INTRODUCTION

157 The objective of this International Standard is to enable common charging interoperability of

158 external power supplies (EPS) used with the increasing variety of computing and consumer

159 electronic devices that implement the IEC 62680-1-3: USB Type-C® cable and connector and

160 the IEC 62680-1-2: USB Power Delivery standards. Broad market adoption of this

161 International Standard is expected to make a significant contribution to the global goals of

162 consumer convenience and re-usability of power supplies by expanding common charging

163 interoperability across different product categories while preserving backwards compatibility

164 with the installed base of billions of IEC 62680 compliant devices worldwide.

165 This International Standard specifies the minimum technical requirements for interoperability

166 and includes recommendations for EPS functionality when used with computing and electronics

167 devices. The approach taken by this International Standard, focused on enabling common

168 charging interoperability, can allow manufacturers to innovate in aspects such as technical

169 design, system performance, and energy efficiency. Furthermore, common charging

170 interoperability enables manufacturers to design specific EPS that match the requirements of

171 target devices (functionality, cost, etc.) and use cases, while at the same time enabling

172 consumers to use the EPS for charging other IEC 62680 compliant devices, across various

173 product types.

174 IEC 62680-1-3 adoption is well underway in global markets for a wide range of devices using

175 as much as 100 Watts including notebook computers, tablets, smartphones, small form-factor

176 desktop computers and other consumer electronics. This International Standard enables the

177 reporting of the identity and power characteristics of power sources (external power supplies

178 (EPS) and other Sources) supported by IEC 62680-1-3 (USB Type-C) and specifies

179 interoperability guidelines when using IEC 62680-1-2 (USB Power Delivery). The method for

180 identification of a specific power source can enable equipment manufacturers to ensure

181 compliant operation using these specifications and promotes data communication that can be

182 used by the device to predict and mitigate interoperability concerns when an unfamiliar or

183 incompatible EPS is connected to the device. EPS power delivery applications can in the

184 future extend beyond 100 Watts given updates to IEC 62680 that appropriately address the

185 needs of higher-power products in the computing and consumer device market.

186 This International Standard also provides important information regarding consumer safety,

187 system reliability as well as relevant global standards and regulatory compliance.

188 Other international and regional standards, and government policies for “universal/common

189 power adapters” that reference this International Standard should take into account open

190 technical and regulatory compliance issues that are associated with untested or arbitrary

191 combinations of EPS and devices such as those identified in Annex A, as well as the

192 limitations and issues with approaches to define “common chargers” in meeting market needs.

193 For clarity, this International Standard focuses on interoperability specifications in order to

194 support global industry in developing safe, convenient, environmentally conscious, and end-to-

195 end interoperable charging solutions that meet regulatory compliance and market requirements.

200 1 Scope

201 This International Standard defines common charging interoperability guidelines for power

202 sources (external power supplies (EPS) and other Sources) used with computing and consumer

203 electronics devices that implement the IEC 62680-1-3: USB Type-C Cable and Connector

204 Specification.

205 This document defines normative requirements for an EPS to ensure interoperability, in

206 particular it specifies the data communicated from a power source to a device (Figure 1) and

207 certain safety elements of the EPS, cable, and device. While the requirements focus of this

208 document is on the EPS (External Power Supply) and the behavior at its USB Type-C connector

209 interface, it is also important to comprehend cable assembly and device capabilities and

210 behaviors in order to assure end-to-end charging interoperability. The scope does not apply

211 to all design aspects of an EPS. An EPS compliant with this standard is also expected to follow

212 other applicable global standards and regulatory compliance requirements for aspects such as

213 product safety, EMC and energy efficiency.
214
215 Figure 1 – Scope of the identification, communication and control method

216 This International Standard provides recommendations for the behavior of a device when used

217 with a power source compliant with this document. This International Standard specifies the

218 minimum hardware specification for an EPS implementing IEC 62680-1-3: USB Type-C. This

219 document also specifies the data objects used by a charging system utilizing IEC 62680-1-2:

220 USB Power Delivery Specification to understand the identity, design and performance

221 characteristics, and operating status of an external power supply. IEC 62680-1-2 and IEC 62680-

222 1-3 focus on power delivery applications ranging to 100W for a variety of computing and consumer

223 electronic devices including notebook computers, tablets, smartphones, small form-factor

224 desktops, monitor displays and other related multimedia devices.

225 Future updates to IEC 62680-1-2 and IEC 62680-1-3 specifications will extend to enable power

226 delivery applications that require more than 100W while remaining within the technical

227 limitations of the USB Type-C cable and connector solution.

228 This document relies on established mechanical and electrical specifications, and

229 communication protocols specified by IEC 62680-1-2 and IEC 62680-1-3. These specifications

282 3.1.7 USB PD power (PDP)

283 the nominal power capacity of the charger defined by IEC 62680-1-2 for use to indicate to

284 consumers

285 NOTE: The PDP rating is indicated both on the USB charger certification logo and within the USB PD source

286 capabilities advertisement to the Sink. For any given PDP rating, the minimum capabilities in terms of supported

287 voltages and currents are deterministic as defined in IEC 62680-1-2.
288 3.1.8 charging cable
289 the cable used between the EPS and device to be charged

290 NOTE: The cable connection to the EPS is a USB Type-C plug per IEC 62680-1-3. The cable connection to the

291 device can be either a USB Type-C plug, a legacy USB plug (e.g. USB Micro-B per IEC 62680-2-2), or a non-USB

292 device-specific connection (either permanent or detachable). Charging cables can be application-specific to enable

293 interoperability between the USB Type-C-based EPS defined by this standard and both existing and future devices

294 and including devices that are not able to accommodate USB Type-C receptacles, e.g. smart watches.
