All the testing info will be available soon. If you check out the front of NorDevX.com I'll be updating about its progress also I'll post it here for people interested. I don't understand what your talking about with the JEDEC standards.

I looked at the A3979 and I finally chose the A3977 simply because it stopped at 1/8th step as I feel like 1/16th step is way overkill. As you would need a machine that was very precisely made for it to be worth it. I however didn't check out the Rds on...that does make its mosfets more efficient I'll have to think about that one.
