Each section of the EVM is designed to serve as an extension to the existing Type-C port that needs protection. The port retains its existing capabilities except for those requiring SSTX/SSRX signals, but with added ESD and short-to-VBUS protection.

TPD4S201-Q1 and TPD4S481-Q1 setup is identical. Connect the Type-C plug to the existing system's Type-C receptacle. Conect a 3.3V power supply to the header pins at the top of the board. The EVM's Type-C receptacle now acts as the existing system's Type-C port. Evaluation of the system can resume as normal. It is advised to use a Type-C breakout board to aid in ESD and short-to-VBUS testing.

Figure 2-1 TPD4S481-Q1, TPD4S201-Q1 Setup

TPD4S480-Q1 is setup in a similar manner. Additional headers for EPR_EN and VBUS_LV signals are provided. EPR_EN may be connected to 0 or 3.3V and VBUS_LV may be monitored via a DMM or oscilloscope.

All three sections contain net ties and 0402 solder pads on the reverse side. By default, the CC1/2 pins are not connected to the RPD_G1/2 pins for dead battery support. If dead battery support is required, cut the two net tie traces and create a solder bridge across the 0402 solder pads. Please refer to the Feature Description section of the device datasheet for additional details to support dead battery operation.
