Can the L6615 load share controller be used for 50V bus high side application? A resistor divider to reduce common mode can be used on the sense pins but how do you calculate the component values?

I am using the L6615 in a 50V bus current sharing application and I have the required voltage divider from each side of the high side current sense resistor to ground but I am unsure if another series resistor needs to be placed in series with the sense pins on the IC.  Any guides on how to calculate these values would be appreciated.  Thanks!
