Thumbs up VTX3D HD7950 Repair Project

Hey guys here's my first in-depth post about this VTX3D HD7950 card I got my mits on.

First look at the card, found several components on the back side were almost knocked off. I've resoldered all the SMD caps & resistors without issue, now to turn my attention to the blown MOSFET (and also the cracked coil)...




I've already ordered several replacement MOSFETs, part # BSC050NE2LS (Infineon) and plan on swapping the full set on the card.

Also on the backside the MOSFET driver looks toast, can anyone help identify this part?



Markings on the IC:
8510
75S-10
U1136

I'm not even going to think about applying power to this card until the driver has been replaced. Can anyone help? Thanks in advance!
