@uhoh Heh, answering that question wrong can get you in trouble ;)

@W5VO well Space SE is much less angsty than Electronics SE, is that the kind of trouble you mean?

I would have to spend more time figuring out how to not go to jail and/or get sued and/or get fined than actually writing the answer.

@W5VO I think writing fact-based answers quoting publicly available sources is the norm for most science and technology-base Stack Exchange sites.

It's likely and old product, and it's on a NASA rover; there should be some information about it somewhere.

@rdtsc lol

Hey are there any KiCad users about?

Maybe @AdamL, but chat here is intermittent. Shoot and someone will eventually answer.

ok cool well basically KiCad is a really awesome circuit design program for linux, i only installed it tonight and just need help with how to add custom components to what is already in it's library, for example the ATMega2560 was in its library, so placing it on the circuit design sheet was straight forward ill show u an image

@AdamL So usually my method is to have my own "custom" library for symbols not in the included libraries.

ok right there are actually a number of good tutes for the program on you tube, i think im at that stage of tired where i get on stack exchange and ask a bunch of menial crap i could easily work out myself if had slept in the past 48 hrs lol

You can make a new symbol library and add new symbols fairly easily. Adding parts to the included libraries isn't a good idea unless you plan on uploading them to the main repository.

I think what you're looking for is kicad symbol and footprint design. The schematic symbol is one entity (viewed in EEschema) while an associated footprint is viewed in PCBnew.

Would anyone have a ballpark figure, on an AC-coupled Hall sensor, powered from +5v, what the maximum output swing could be?

I have a Hall which looks like an Infineon TLE4921-5U but outputs an AC signal. Given 5v, I'm seeing fairly common spikes beyond +5/0v and even one to +15v. Is this common?

Current-sensing on a 460A motor soft-starter.

Since the chip is probably custom, what are the chances it has built-in charge pumps for +/-15v output? Has that ever been done?

So that's an open-collector digital output...

At 400+A, what kind of signal does it give when it's not powered (e.g. VDD and VSS connected together at the source)? AC coupled in this case just means that it filters out the "steady-state" DC response.
