IPROPI/ITRIP Current Regulation - Confirmation of Understanding (as not explicitly stated within datasheet)

Tool/software:

Hi TI Forum,

I would like to power a RS550 DC Motor, but limit the maximum current it would receive to ~18A. I have designed the following circuit and would just like to check my understanding of the ITRIP/IPROPI regulation and get feedback if it's correct? I have included calculations within the schematic itself.

Additionally, is there anything else that I'm missing from the design? Or incorrect values?

Thanks Darren
