TI offers ESD protection diodes with options to protect USB 1.0/1.1. Figure 3-4 shows a block diagram implementing three 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 3-4, ESD321 is used to the protect the D+ and D- lines and ESD441 is used to protect the VBUS line. There is also an option to use one ESD diode that protects both the data and power lines. For this to work, the diode is recommended to have a working voltage greater than or equal to 5V. A device that can handle both data and power lines is TPD4E05U06.
