IEC 62684:2018 pdf download.Interoperability specifications of common external power supplies (EPS) for use with data-enabled mobile telephones
1 Scope
This document specifies the interoperability of common external power supplies for use with data-enabled mobile telephones. It defines the common charging capability and specifies interface requirements for the external power supply. Safety and EMC aspects are not covered by this document. Safety is covered by IEC 60950-1 or IEC 62368-1 and EMC is covered by regional /national standards. This document defines interoperability based on legacy USB technologies and does not cover charging interfaces that implement IEC 62680-1 -3 (USB Type-C™ 1 ), IEC 62680-1 -2 (USB PD) and IEC 63002. NOTE: The content of this document is based on Annex II dated 1 2 January 201 0 to the MoU regarding Harmonisation of a Charging Capability for Mobile Phone.

3 Terms, definitions and abbreviated terms
3.1 Terms and definitions For the purposes of this document, the following terms and definitions apply. ISO and IEC maintain terminological databases for use in standardization at the following addresses:
4 EPS specification
4.1 DC plug connector specification The cable assembly supplied with the EPS shall terminate in a USB Micro-B plug, defined in IEC 62680-2-2. The cable assembly may be permanently connected to the EPS or may be a detachable cable. In either case, the terminating USB Micro-B plug shall be compliant with the USB Micro-B cables and connectors specification, IEC 62680-2-2. The cable assembly supplied with the EPS may also terminate in a non USB Micro-B plug if a manufacturer makes available an adaptor from the Micro-USB connector of a common EPS to a specific non-Micro-USB socket in the mobile phone. 2 An EPS provided with a detachable cable shall be equipped with a USB Standard-A receptacle to connect to the EPS. The detachable cable assembly, supplied for use with the EPS, shall have USB Standard-A and USB Micro-B plugs and meet the USB-IF cable assembly requirements in IEC 62680-2-2. The above requirement also applies to a cable used as an adaptor, i.e. when the USB Micro-B is connected to the mobile telephone by an adaptor where the mobile telephone does not have a Micro-USB interface.4.4 DC output characteristics The DC output voltage of the EPS shall be as specified in IEC 62680-2-1 . The cable voltage drop shall be as specified in IEC 62680-2-1 . The ripple voltage on the output with a no-load current to maximum rated output current shall be no more than 80 mV peak-to-peak measured at 20 MHz bandwidth when measured in accordance with the test method defined in 5.2. Proprietary methods for faster charging at higher voltages and/or currents are permitted, provided that interoperability according to IEC 62680-1 -1 is guaranteed when the peer connected device (EPS or the mobile telephone) supports only IEC 62680-1 -1 .
