4.3 System Level Designs

TI has a range of ESD diodes with options to protect USB 5Gbps. Figure 4-1 shows a block diagram implementing four ESD protection diodes. The diodes are connected to each data and power line between the connector and either the battery charger or 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 4-1, ESD321 is used to the protect D+ and D-. TPD4E02B04 is used for the TX/RX lines. There are a few other options for protecting the D/TX/RX lines such as using a 6-channel device, using multiple 2-channel devices, or even using 1-channel devices. ESD441 is used to protect the VBUS line.
