Hi WChai,
there is a pdf file attached to my last post, I can see it. Please check again and maybe try a different browser.
hotswap design are not simple and there are a lot of things to consider to make a truly robust design. I strongly suggest you to have a read of the design guide and datasheet.
Rsense=20mV/limit, where Ilimit is the current limit you want to set. Typically it will be you peak load current plus some margin, depending on how regulated your load is, typically and extra 20-50%.
for example for a 60A maximum load system, set the current limit around 80A.
to set 80A current limit, 20mV/80A=0.25mR. You may use two 0.5mR sense resistor in parallel (be aware of the power dissipation in Rsense).
if you want to set a current limit of 70A, 20mV/70A=0.285mR, that's not easily achievable. what do you do? that when ISET comes handy. adjust the Vsense_limit to 17.5mV and then the same two 0.5mR in parallel will give you 70A.
again, take a look at the datasheet and user guide, ask again if you stuck with any specific question.
