LM3424 What to do w/ unused thermal foldback pins

Other Parts Discussed in Thread: LM3424

Hi all,

If I am not using thermal foldback on the LM3424, what should I do with the unused pins TSENSE/TREF/TGAIN?

I referred to this E2E thread:

However, with regard to tying TGAIN to VCC to turn off the comparator, VCC nominal output is 6.9V while the absolute maximum for TGAIN is listed as 6.0V, so isn't that a problem? What should I really do with TGAIN?
