Nevertheless I've seen different results using different devices, though those devices both have higher gate threshold voltages and larger on-resistance at those gate voltages.
I appreciate that you've taken time to change the source current as I asked, but am now even more curious why, exactly, I've gotten away with this approach in these recent cases. We'll see where I've gone wrong, I guess. Fortunately, I don't do this sort of thing often. I did a similar thing with that reset test setup, though I was switching supply to a regulator and had some headroom. That thing ran for about six weeks without a hiccup, and everything looked/measured just fine. RE |
