LTC4364: MOSFETs Rds(on) instead of Rsense

Hello,

I'm building high current power source and plan to use LTC4364 as a ID controller and current limiter in case of short circuits events at output.

To be effective I've thought of using FETs Rds(ON) as a Rsense for current limiting feature. Can you advise if this method possible in this controller and application?

Thanks
