Here's the trick:
We have absolutely no idea what you mean by a "half-bridge mosfet driver". There could be dozens, even hundreds of things that could be so described - have you thought about that? Just because you have something in front of you which is called a "half-bridge mosfet driver" actually tells us nothing at all.
So you must convey to us what it is you actually have. I suspect you bought it somewhere, so tell us the Web link to the item (because in this day and age, that is how people buy things) so that we can figure out what it is, what its circuit is and how you need to drive it and of what it is capable.
