LM5069: Constant Current Source

Part Number:LM5069

I wonder if I can use this IC as a controller for a constant current source. I am thinking of connecting a MOSFET in parallel with the TIMER capacitor, so after a successful startup, the PGD pin activates the parallel MOSFET and thus, the voltage across TIMER capacitor never reaches its fault threshold. Do you think in this case the IC will continue to set the right gate voltage for the main MOSFET to pass the desired (1A) current? Of course, this is assuming that I dissipate the losses from the main MOSFET. 

I also had a question regarding UVLO and OVLO functions... So, if a fault was detected, does the IC return to normal operation after it was cleared (and the main voltage falls within the limits again)?
