The example shown in Figure 6-2 is for connections to a USB 3.2 Type A connector to support
host only. Recovery mode is not supported.

Notes:
1. AC capacitors should be located close to either the USB connector, or the Jetson Xavier NX
pins.
2. Connector used must be USB Implementers Forum certified if USB 3.2 is implemented.
3. The load switch supplying VBUS should have over current protection. In Figure 6-2 this is
supported by routing the over current (OC) pin of the load switch to the GPIO00
(USB_VBUS_EN0) which is bidirectional and can be used to detect an over current condition.
