Automotive USB Type-C ports

After becoming the de-facto standard for both high data rates and device power supply and charging in computing and consumer applications, USB Type-C is now establishing itself in automotive applications. While the high-speed data transfer capabilities are often optional, charging capabilities in line with the USB Power Delivery (PD) specification are essential. Besides design simplicity, system robustness and reliability are especially important for use in automotive applications.

Design considerations

  • USB Power Delivery (PD) over Type-C connectors supports flexible power profiles up to 100 W and up to 240 W with Extended Power Range (EPR). This requires power control switches capable of handling voltages of 20 V or higher with robust reliability.
  • Low on-resistance (RDS(on)) is essential to minimize conduction losses, reduce thermal stress and ensure compliance with USB minimum-voltage specifications
  • Electromagnetic compatibility (EMC) poses significant challenges, as both internal power supply dynamics and external automotive conditions can introduce severe disturbances such as ESD, surge events and electrical transients.
