LTC4261 max time limitation of timer

Category: Hardware
Product Number: LTC4261

our customer wants the waiting time after OC fault up to 2S, i just wonder if i can set the timer time for 500mS to fulfill this requirement?

Any max limitation for the time of timer, 

Whether the long timer will pose extra stress to the mosfet? 

-48Vin, Vinmax 72V,

current limit 1.7A, 

mosfet csd19531q5a

we test the 2.2uF timer cap and found no difference between on short circuit, original I think it may impact the SOA of MOSFET during short circuit test.
