ISO5452-Q1: Input to Disable Gate Driver Outputs?

Part Number:ISO5452-Q1

Hello, 

For the ISO5452, can I drive the RESET pin with an active low signal to disable the outputs? I have windowed comparators that trigger for overcurrent events on the 3 phases and then another to trigger for a overload on the DC bus. I want to feed the output of those comparators to a logic gate where the output will bypass the processor and go directly to the gate driver to open the IGBTs in case of a overcurrent or overload event. The reason for this is to reduce propagation delays and latency. 

I see the UCC21520 has a DISABLE pin. That is exactly what I want. Can the RESET pin on the ISO5452 do what the DISABLE pin does?

Thanks

Jason
