This is a 16 pin chip made by micrel, used in a garage door opener(motor & light control board). I believe it has one input which ultimately controls mult. outputs, I cant find any info on this IC. Hope someone can!

Presumably it's a pre-programmed microcontroller, so there probably won't be any info available?.

Just my luck. Well since I posted this thread Micrel did contact me back after they told me this was an invalid part #. They did say that they produced this particular chip for a manufactor and no data sheet is available to anyone. So I just had to order the whole board for this unit in order to fix problem.
