Have a look at figure 7 in the data sheet. To parallel two ICs, I assume it would be fine as long as you used separate current sense resistors to make sure the load is balanced.

I read it , but i didnt understand it fully ? you mean i must put 4 current sense resistors then for the two ICs ?

If you look at figure 7 then you should only need two.

I think I need a break.
