Re: Brownout behavior - alternative design goals

OK. Time for me to make another post that will come off sounding more defensive that I intend for it to.

The link to the user manual and spec sheet of the roboRIO was intended to clarify the design and spec'ed behavior with low input power. The link to team 358's results were to intended to show how an alpha team tested the more complete system that included USB devices, rail power, VRM, etc. I'm not trying to sell you a used car or use a single team's testing to fool anyone. I'm giving the info I know of for the roboRIO and system elements that were delivered. That may help you or others on this alternate design quest.

As for the other background on short protection -- I described the additional protection mechanisms so alternate designs would be apples-to-apples.

As I described in my background, I don't have the chops to do the current or alternate power supply design. But I do volunteer as a team mentor and CSA, so that I can see first-hand how the elements are used and how they perform. From that perspective, as a customer and support engineer, I do not see the need for the 1V or even 3.3V input requirement.
