HD3SS3212: TUSB319+HD3SS3212 SCH review

Part Number: HD3SS3212
Other Parts Discussed in Thread: TPS2549, TPS2546

​Hi team,

Customer now use our TUSB319+HD3SS3212. And found that if follow the ciruit in HD3SS3212 datasheet, the PCB route is very difficult.

So may I ask the following questions based on customer's SCH. 

1. The CC pin of tusb319 and the CC pin of the connector have been exchanged, then the output high/low level of pin5 of 319 will also be exchanged when plugging in reverse.

Then the cable connecting the connector to the HD3SS3212 has also been changed. Will this be a problem?

2. Is the P/N inside HD3SS3212 just a switch? You will find that customer is connecting the P of the connector to N of the HD3SS3212. Will this exchange affect the communication?

3. Also help to check USB Vbus Switch (with charging protocol such as BC1.2/Apple) Does TI have low-level enable? So I can omit SN74VC1G06. Chips like TPS2546/TPS2549, but both of them are high-level enable​
