Hi,
We have some questions related with TUSB322I.
- DIR pin operation.
Datasheet said "DIR of plug. The open drain output indicates the detected plug orientation: Type-C plug position 2 (H); Type-C plug position 1 (L)." If TUSB322I detects CC2 position, TUSB322I outputs open on DIR pin, but High due to external pull-up resister. Is it correct?
Also, How about non-connection status? If TUSB322I has not detected CC1/CC2, TUSB322I outputs open and same behavior as CC2 detection. Is it correct?
- EN_N pin treatment
Is it OK to connect GND with EN_N pin directly? Although EN_N pin is directly connected with
GND on typical application circuit of the datasheet, I want to re-confirm it. Please let us know.
- INT_N/OUT3, ID pin pull-up resister.
According to the datasheet, pull-up resister of INT_N/OUT3 pin and ID pin recommends 200kohm. However, due to external CPU requirement, he wants to reduce 10kohm pull-up resister. If you know any issues to use 10kohm resister, please advise us.
Thanks and best regards,
M.HATTORI.
