Understanding the EU Common Charger Conformance Testing

This white paper outlines the EU Common Charger Directive, which mandates that all portable electronics utilize USB-C for charging. The directive aims to reduce electronic waste and enhance consumer convenience by standardizing charging interfaces across devices. The document details the collaboration between the International Electrotechnical Commission (IEC) and the USB Implementer’s Forum (USB-IF), which has established a streamlined program for manufacturers to verify compliance with the directive. The paper describes the conformity program set up by the USB-IF, which includes various tests for different product types, such as external power supplies and USB Type-C cables. It also discusses the Teledyne LeCroy Voyager M310e, a USB protocol analyzer designed for IEC conformance testing, highlighting its capabilities in supporting USB Power Delivery and Type-C compliance. The paper concludes by emphasizing the importance of this initiative for consumer convenience and environmental protection, as well as the need for automated testing tools in the industry.
