HDD GURU FORUMS

Anyone ID this and locate a datasheet for me - my google foo has failed.

Markings UaASB (at least it looks like a lowercase a). I'm getting some odd delayed power readings on one of the pins and could really do with the datasheet.

I'm guessing it's a Silergy part, in which case the marking code would be Uaxyz. My usual searches don't turn up anything, though.

Good to know it wasn't just me being myopic then. I'll keep digging and I've ordered a donor so that might help.

If the PCB is a reference design, then other manufacturers may use a recognisable equivalent part.
