Hi Jpkozak,
Analog devices does have devices specifically for your application. I'll need to know a few more things to fully define the part, but check out our ADuM3223. This part was designed for half-bridges, and with an isolated DC/DC source, your can float one or both of the channels. Another part similar to the ADuM3223 is the ADuM7223 if a smaller footprint is desired.
It sounds like you might be looking for a complete monolithic solution. If your switching frequency is low enough, check out the ADuM6132. These parts have an isolated DC/DC converter built right into the part.
What kind of switching frequency and how big of a MOSFET are you operating? By size, I'm mostly interested in the Ciss of the part, or the gate charge. These numbers will dictate whether you could operate with the ADuM6132, as there is a limitation to the isolated current they can put out.
