USB Type-C Compliance with EN IEC 62680

EN IEC 62680-1-3 specifies the requirements for USB Type-C cables and connectors, while EN IEC 62680-1-2 outlines the fast-charging protocol based on the CC channel in Type-C connectors. Below are the detailed descriptions:

EN IEC 62680-1-3

Physical Characteristics:

- Pin Definition: Specifies the functional assignment of the 24 pins in a USB Type-C connector, including power pins, data transfer pins, and ground pins, ensuring accurate electrical connections and compatibility between devices.

- Mechanical Structure Requirements: Defines mechanical parameters such as the dimensions, shape, and plug/unplug force of Type-C connectors. For instance, it mandates that connectors must withstand at least 10,000 plug/unplug cycles to ensure durability.

- Dimensional Requirements: Clearly defines the tolerance range for Type-C plug and socket dimensions to ensure physical compatibility across devices manufactuRED by different vendors.

Electrical Performance:

- Power Delivery Capability: Outlines the different power modes and corresponding power transfer capabilities of the Type-C interface. For example, Type-C connectors supporting the USB Power Delivery specification can deliver up to 100W, meeting the charging needs of high-power devices such as laptops.

- Signal Transmission: Specifies electrical signal characteristics for high-speed data transfer, such as signal rise and fall times and eye diagram templates. This ensures stable high-speed data transmission over the Type-C interface, supporting protocols like USB 3.2 and USB4.

- Electromagnetic Compatibility (EMC): Establishes requirements for electromagnetic emissions and immunity. It limits devices' electromagnetic interference with other electronics during operation and ensures stable performance in complex electromagnetic environments.

EN IEC 62680-1-2

Fast Charging Protocol:

- Negotiation Mechanism: Enables communication between power-consuming and power-supplying devices through the CC channel in Type-C connectors. This allows negotiation and adjustment of voltage, current, and charging direction. For example, when a smartphone is connected to a fast charger, the two devices negotiate an appropriate charging voltage and current via the CC channel to enable fast charging.

- Power RULes: Defines charging voltage and current ranges for different power levels. For example, in low-power charging mode, the voltage might be 5V and the current 2A, while in high-power fast charging mode, the voltage can increase to 20V and the current to 5A.

- Safety Protections: Includes safety mechanisms such as over-voltage protection, over-current protection, short-circuit protection, and over-temperature protection. These safeguards ensure safety during charging by automatically cutting power or adjusting parameters in the event of abnormalities, preventing harm to devices and users.

Applications

- Consumer Electronics: Devices like smartphones, tablets, digital cameras, headphones, headsets, portable speakers, handheld gaming consoles, and e-readers. Starting December 28, 2024, electronic products sold in EU member states must feature USB Type-C charging interfaces compliant with EN IEC 62680-1-3 and support fast charging technologies compliant with EN IEC 62680-1-2.

- Computers and Peripherals: Laptops sold in the EU from April 28, 2026, must include USB Type-C ports. Additionally, peripherals like keyboards and MICe are increasingly adopting Type-C interfaces for easier connectivity and charging.

- Docking Stations and Adapters: Devices like docking stations for connecting computers to multiple peripherals, and Type-C to HDMI or Type-C to VGA adapters, must comply with EN IEC 62680 standards to ensure compatibility and stable performance across devices.
