This is from a VP7-3ATI LCD Controller from Westar. The reference for the part on the board is U31enter image description here

The best I can tell is the text on the chip says either "B7AK" or "87AK" but I'm not sure. I couldn't find the part number in Westar's documentation and have not had very much luck with googling the markings. Any ideas would be awesome, thanks!
