IEC 62684 pdf download.Interoperability specifications of common external power supply (EPS) for use with data-enabled mobile telephones
1 Scope
This International Standard 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 the external power supply. Safety and EMC aspects are not covered by this International Standard. Safety is covered by IEC 60950-1 and EMC is covered by EN 301 489-34.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 60950-1 :2005, Information technology equipment – Safety – Part 1: General requirements EN 301 489-34 Electromagnetic compatibility and Radio spectrum Matters (ERM); ElectroMagnetic Compatibility (EMC) standard for radio equipment and services – Part 34: Specific conditions for External Power Supply (EPS) for mobile phones Universal Serial Bus Specification, Cables and Connectors Class Document, Revision 2.0, August 2007 (http://www.usb.org/developers/docs) USB Battery Charging Specification, Revision 1 .1 USB Micro-USB Cables and Connectors Specification, Revision 1 .01 USB-IF Cable Assembly Test Requirements for Compliant Usage of Connectors and Cables in Micro-USB 1 .01 USB-IF Connector Test Requirements
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply. 3.1 adaptor device for connecting from a USB Micro-B receptacle/plug to a specific non Micro-USB connector NOTE An adapter can also be a cable.
5 EPS specification
5.1 DC plug connector specification The cable assembly supplied with the EPS shall terminate in a USB Micro-B plug. 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 meet the USB-IF connector test requirements, – shall be compliant to the USB Micro-B cables and connectors specification, Rev 1 .01 (Micro-USB 1 .01 ) and – shall be rated to meet all electrical specifications. An EPS provided with a detachable cable shall be equipped with an USB standard A receptacle to connect to the EPS. The detachable cable assembly, supplied for use with the EPS, shall have Standard A and USB Micro-B plugs and meet the USB-IF cable assembly test requirements for compliant usage of connectors and cables in Micro-USB 1 .01 . The above requirement also applies to cables 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.5.4 DC output characteristic For EPS with permanently connected cables, the voltage at the USB Micro-B plug of the EPS shall be 5 V ± 0,25 V with no load current to rated output current. For EPS with detachable cables the voltage at the USB standard A receptacle shall be (5 ± 0,25) V with no load current to rated output current. The maximum voltage drop caused by the detachable cable shall be 1 25 mV when measured across the power pair pins of the USB Micro-B plug, while drawing 500 mA from a nominal 5 V source. The minimum rated output current shall be 500 mA. The maximum rated output current shall be 1 500 mA. The maximum output current at any voltage shall not be greater than 1 500 mA. 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 using the test method as defined in Clause 6. The common mode noise at the DC output when measured in accordance with Clause 6 shall be – AC voltage frequency component: 95 V peak-to-peak maximum, – EPS switching frequency component: a) the peak-to-peak voltage measured in the frequency range of 1 kHz to 1 00 kHz shall not exceed 1 V peak-to-peak; b) the peak-to-peak voltage measured in the frequency range of 1 00 kHz to 400 kHz shall not exceed 200 mV peak-to-peak; c) the peak-to-peak voltage measured in the frequency range of 400 kHz to 1 MHz shall not exceed 39 mV peak-to-peak; d) the peak-to-peak voltage measured in the frequency range of 1 MHz to 1 00 MHz shall not exceed 20 mV peak-to-peak; e) the occupied bandwidth of the fundamental measured with peak hold shall not exceed ±1 0 % of the EPS switching frequency; f) the maximum amount of slew within any 1 00 ns window is 1 ,25 V peak-to-peak. NOTE Noise in the FM and TV bands from the EPS should be minimized as it may cause interference to any FM radio and/or TV function of the mobile telephone to which the EPS is connected.
