TUSB320 CC pin Design

Other Parts Discussed in Thread: TUSB320

Hi Expert,

If TUSB320 VDD is 3.3V, the max voltage rating would be VDD+0.3V. (3.6V)

When the VBUS(5V) shorted to CC pin, that the CC pin would be damage? I have checked some TI ESD solution, we don't have 3.6V parts.

What's your suggestion? Thanks!

Hello Jerry,

I am really sorry for the delay, I am reviewing your post and I will provide an answer within a couple of days (due to heavy work load).

Regards,
Diego.

Hi Diego,
Ha, no problem. But local FAE suggeseted to add the divide resistor to prevent it. I am sure does it make sense.

Hello Jerry,

I've confirmed that the CC pins support up to 6V, we are working on update the DS.
