Key Document


This USB Power Delivery (PD) reference design is a TPD6S300A integrated chip set into a USB Type-C passthrough board. This design simulates the application where two Type-C ports with short protection circuit are connected and offers an easy way to manually short VBUS to the CC and SBU pins. To demonstrate this functionality, connector sides of both the devices are used in conjunction with pushbutton switches.

  • Buttons to short CC, SBU pins to VBUS
  • Test points for CC, SBU, VBUS and VIN_3V3 pins
  • Overvoltage protection on CC and SBU pins
  • IEC 61000-4-2 ESD protection on CC, SBU, DP, DM pins
  • Wide input power supply for non-compliant Type-C products
