TUSB320: Varistor on CC1/CC2

Toshiro Imi

Part Number: TUSB320

Hello,

A customer is planned to place a varistor (variable resistor) on CC1 and CC2 and he requests our opinion.

Could you have any opinion or suggestion if he plaices a varistor on CC1 and CC2.

There is no resistor needed on CC pin, why customer want to place resistor on it?

Hi Brian,

No. I think this customer will uses varistor, which is usually used for preventing ESD or surge event. Varistor is usually placed on a I/O to GND.

CC signal is very slow speed, so there is not much concern about it.
