IEC 62637-1:2011, Battery charging interface for small handheld multimedia devices – Part 1: 2 mm barrel interface
3 Abbreviations and symbols
For the purposes of this document, the following abbreviations apply.
4.Test conditions for the 2 mm barrel charging interface
4,1General test conditions
The general test conditions are set out below. Manufacturers should note that the actualconditions of use could be more stringent.
Tests conducted using this conformance document do not replace EMC, ESD, safety, typeapproval, or any tests set by legislation in the chargers or devices using the charginginterface specified in IEC 62637-1. The purpose of the conformance testing is to achieve goodinteroperability between different chargers and devices.
4.2Temperature
All measurements shall be made at normal room temperature 18 C to 25 C, unless someother temperature is specified.
Voltage4.3
All tests are performed under nominal operating voltage as defined by the manufacturer
Electrical testing of 2 mm barrel type chargers5
5.1Maximum transient voltage and current values
5.1.1Test purpose
The purpose of this test is to verify that the charger complies with the requirements of settlingtime, minimum voltage and maximum voltage limits specified in IEC 62637-1, 5.2.
5.1.2Requirements
The following requirements apply.
Maximum charger output overshoot shall be less than or equal to 16 V.
Maximum reverse voltage at charger output shall be less than or equal to 1 V.Maximum time to achieve steady state value for voltage and current ( + 10 % tolerance)after load change (“no load”/”normal load”) shall be less than or equal to 10 ms.
Maximum duration of charging current overshoot peak value greater than 1,1 A shall beless than or equal to 5 ms.
