BQ24780S: unused pin

Guru 29720 points
Part Number: BQ24780S

Hi Team,

I believe the following pins could be floating if unused.
Is my understanding correct?
--------------------------------
PROCHOT# (10)
TB_STAT# (16)
BATDRV (18)
--------------------------------
My customer considers to use BQ24780S for a charging only system and it doesn't need path from battery to system. (BATFET doesn't be required.)

Best Regards,
Yaita / Japan disty
