7.3 System Level Designs

TI has a variety of ESD protection diodes able to protect each pin of a USB Type-C® connector. Figure 7-2 shows a block diagram implementing single-channel ESD protection diodes. The diodes are connected to each data and power line between the connector and USB controller. To properly protect the system, place the diodes as close to the source of ESD, in this case the connector, as design rules allow.

For Figure 7-2, TPD1E04B04 is used to protect the TX/RX lines, ESD321 is used for the D+ and D- lines, ESD441 is protecting the CC pins and VBUS, and ESD341 is used to protect the SBU pins. There are many options for protecting USB Type-C® including using multi-channel devices.
