Hey guys.. I was just curious. Do you know of any lookup tools for IC's that can look up chips based on pinouts? I don't assume that that would be a feasible concept for things like high pin count microcontrollers and above, but it seems like the kind of thing that could exist for smps chips or the like. So I was curious.
To elaborate, say you were looking up an 8 pin SMPS chip for a device, but couldn't find anything based on the IC number. It would be really cool to be able to say, "Ok, this pin is driving the MOSFETs, this pin is ground, this pin is vcc, this pin looks like current sense, and I'm not sure what these pins are" and then get some possible chip lookups from that. This concept popped in my head the other day when I was working on a PSU for a friend and couldn't find the actual chip's datasheet. I eventually found what it was a clone of after some searching (it ended up having parts number similarities with the original), but it ended up taking quite a while to track down..

I think more people would see them than they would on this thread. haha
