TUSB320HAI CC terminal connects to GND

Hirotaka Inoue

Hi support member,

The datasheet shows that maximum current(Icc_HIGH_P) of CC is 356uA.
Then, is device no problem, if CC terminal connected to GND?
Concerned situation is that CC terminal is connects to GND of type-c connector by entered water.

Helo Hirotaka-san,

There is no issue on connecting the CC pins to GND, in fact the 356uA is the case when the CC pin is connected to GND.

Diego.

Hello Diego-san,

Is there no issue, if the condition continues long time?
For example a few hours.
I expect that it is no issue since this current value is too small as Iout.

Hello Hirotaka-san,

That shouldn't be an issue, but I am wondering why the customer would face such scenario???
