USB Type-C connectivity

USB Type-C has become the standard USB connector for a multitude of applications, offering both high-speed data transfer and fast and efficient battery charging. In fact, USB Power Delivery (PD) has become an almost universal charging standard in both the smartphone and laptop markets, meaning USB-C plugs and cables are increasingly common. But mixing power with data requires a range of ESD protection solutions, each optimised to their specific task and data rate (10 Gbit/s Superspeed or High-speed for auxiliary data and audio).

Design challenges

  • The extra performance and convenience offered by USB-C makes for more complex circuitry on the PCB 
  • USB PD via Type-C connectors allows for various power profiles up to 100 W, requires power control switches to be capable of withstanding 20 V or higher
  • Low on-resistance is a pre-requisite to minimise energy loss, unwanted thermal challenges, and to comply with USB minimum-voltage regulations
  • Designers need to pay careful attention to the trade-off between TVS terminal capacitance (Ct) and the available ESD protection level - to avoid data distortion while ensuring system robustness
