Can I power the TUSB320LAI VDD with VBUS if I am using a TPD1S514-1 to protect the supply ?
In the data sheet for the TUSB320LAI it states Recommended VDD Supply voltage range : 5 Max, however in Fig. 20 it states "Optional power TUSB320 with VBUS less than 5.5V" and the Absolute Max Raing fro VDD = 6V.
The TPD1S514-1 has a VBUS_SYS ramp = 23.5mS, Vovp = 5.99V max and Tovp = 100nS !
Another option is TUSB321A or TUSB322 which are designed to be powered via VBUS as they can support VDD up to 5.5V. TUSB320 is rated only to 5V.

Shmuel,
As Brian mentioned the TUSB320LAI was rated at 5V. Despite the discharge circuit reduces the voltage below 5V, the condition of 5.99V ~100ns could affect the device. Hence, TI cannot guarantee the proper performance in this condition. Please take a look in another options.
Thanks,
Luis
