If you don't need the bridge to be fully on (100% duty cycle), and the supply voltage is 30V or less, then you have a choice amongst a few different vendors. DigiKey carries Linear Technology's LT1162. Harris makes (made?) them as well (I have used the HIP2500, but it has been obsoleted since then). Those are the only ones if have played with, but there are many others. It isn't really hard to roll your own. IR especially has lots of good app notes on this subject. But it's definitely easier to buy a driver IC.
