TUSB1146: PD, Industrial Temperature

Part Number: TUSB1146
Other Parts Discussed in Thread: TPS65994AD, TPS65981,

Hello,
I'm trying to figure out the smallest PD to work with the TUSB1146 and support industrial temperature. The EVM PD controller used doesn't support -40-85C. About the only one I've found that does is the TPS65994AD and the TPS65981. It seems like the TPS65994AD is smaller even though I only need one port. Would that still be my best option?

Thanks,
Brian

If the TPS65994AD is my best option, which it seems like. Where can I find what to do with unused pins? The datasheet doesn't seem to list it and most posts seem in e2e seem to go to having conversations through messages or email instead of e2e. My plan is to not use port b, nor will I need the VSYS.

Thank You.
