Hi Team,

    My customer is using HD3SS6126 and output connector wold be type C USB 3.0. They want the USB host can work with the cable orientation detection. They want to use CC pins(High/Low) to switch HD3SS6126. Following is block diagram planning would be and need your help to see if workable or not. 

    ( The output is fixed for 5V/0.9A.)

    Please refer to USB Type-C spec. There are different states besides the sink attached state associated with the CC1 and CC2. You should use the TUSB320 CC controller to drive the HD3SS6126 SEL pin instead directly driving the SEL pin using CC1/2.

    Thanks
