I think its the fod8316. I'm on my cell phone, and its a little hard to check. it drives 600v 600amp igbts no problem at 10khz.
Oh, the criminal that was not doing his job properly, I can guess

I cant stock those here in the UK, but a quick look shows the TI ISO5500DW and the Avago ACPL-339J-000E as possible replacements.

Do you have some unpopulated boards you could sell for these? looks like a fairly decent solution.
