look at the dimensions of that thing, it's kind of ridiculous. IR, TI, ON, Linear all have offerings in this arena with standard packages and better performance. Personally I would pick something with a high-side driver, such as this:

less than $1 and will drive a pair, low side plus high side.

There's better matches out there, that was just a 5min google search..

to deal with a package as large as the one you posted I would expect it to drive all 6 fets/igbt's in a standard 3-phase motor control setup.
