Jim,
I will be following along as I am building a layout that has a YD7001 and a DR5033.?
Have you tried adjusting the speed at which the YD7001 triggers a short? It might just be reacting faster than the DR5033 has time to reverse polarity.?
Bruce, I would email Ryan and ask if he has any information on availability. My assumption, even if there is another retailer, that Ryan at IPH is the importer for everyone in NA. My assumption could be wrong.?
