What is this IC?

[james_s]

My google-fu is failing me today. I'm trying to find a datasheet for this IC, I believe it's a mosfet half bridge, looks like it's made by International Rectifier and looks like P542G, I expected this to be easy but I've come up dry. Anyone got a link?

Thanks, I must be tired, for some reason I assumed that number was a date code and a quick search of it didn't net much either, dunno. Anyway that looks like the right part and matches what I've worked out from the circuit.
