LM74722-Q1: LM74722-Q1 - Single gate driver?

Tool/software:

Hi everybody,

I'm looking for a high side gate driver for my system: the component should be able to open a MOS whenever a sensed voltage overcomes 20V (in the LM74722 case I would use the OV pin for this).

This is the architecture so far:

The MOSFET Driver block is what I'm looking for right now.

I was wondering if the LM74722-Q1 could drive a single MOS only (the one connected to pin PD), since its price and size are very good, compared to usual gate drivers. 

If not, is there any other component you suggest to use for this application?

Thanks a lot!
