Overview
IEC 62680-1-2:2024 specifies the USB Power Delivery (USB PD) system architecture, protocols, power supply behaviors, connectors, and cabling for Universal Serial Bus (USB) interfaces used for delivering data and power. Developed by the International Electrotechnical Commission (IEC), this seventh edition aligns with the USB-IF Universal Serial Bus Power Delivery Specification Revision 3.2, Version 1.0. The standard is designed to ensure interoperability across various USB devices, supporting power delivery up to 100W while maintaining backward compatibility with earlier USB infrastructure.
Key Topics
- Comprehensive USB Power Management: Details the mechanisms for negotiating and managing power delivery among hosts, devices, hubs, chargers, and cables in USB systems.
- Expanded Power Capabilities: Supports power profiles up to 100W, facilitating rapid charging and powering of a broader range of devices, including laptops, tablets, and smartphones.
- Extended Power Range (EPR): Integrates the EPR including Adjustable Voltage Supply (AVS) to offer higher voltage and flexibility for advanced charging scenarios.
- Protocol and Communication: Specifies communication protocols, power rules, and role swapping for dynamic allocation of power between connected devices.
- Connector and Cabling Requirements: Defines both standard and advanced requirements for connectors (such as USB Type-C) and cabling, enabling safe and efficient power transfer.
- Backward Compatibility: Ensures seamless integration with existing USB devices and systems for optimal market flexibility and product differentiation without sacrificing legacy support.
