Jim designs custom IC's, so (I assume) he's concerning himself with it
so he can make the output stage of his circuit both economical and
robust. He may even care about making the relay turn off quickly.

It seems like a perfectly valid concern to me, even if the circuit in
question _isn't_ custom -- what if you're powering the relay from
logic, and want to insure fast & safe turn-off?

Dead-on, Tim!

Like this...

http://www.analog-innovations.com/SE...elayDriver.pdf

In the discrete world, with more voltage tolerance available, you can
scale this to larger controlled flyback potentials, for fast turn-off.

...Jim Thompson

Clever. I assume that the gate threshold of MP1 guarantees that the
drain of MN1 never exceeds your max voltage?

I could see a potential for this to oscillate on turn-off, with the
inductor working against the delays in the two FETS, but if it did it may
well not matter, and your relay coil is probably sluggish enough to keep
it from happening anyway.

Do you get to tune the gate thresholds of the individual parts, or is
that usually locked in by the process?

stating "all the processing is going to be done digitally" without ever
answering the question "but how is the information going to get in, and
the commands out?"

Because you can design the best damn DSP in the world, but if you feed it
inputs that are filled to the brim with gallons of ground bounce,
egregious thermal noise, nonlinear effects and timing jitter with maybe a
teaspoon full of real signal, you aren't going to have a good system.

Would not the real question be why would someone concern himself with
the
solenoid inductance of a miniature relay? I could see it if it were
huge.

L di
E= ------,
dt

so the diode damping the "spark" when the driver went open would slow
down the opening of the contacts, maybe?

Or maybe the magnetic field building up and breaking down might affect
some nearby component?

Dunno...

JF
ISTR an appnote floating about on the net that recommends using a
combination of diode and zener to clamp the back emf, apparently if you
just clamp it with a single diode, the back emf drives a current round
the
diode/solenoid circuit which causes hesitant unlatching.
Probably this one?

Show me where that was ever stated, you fact morphing retard!
Quote from life imitates life,
" I am quite certain that any 3.3V relay you choose to examine will prove
to be faster than any of the numbers that more than 10 year old document
measured. Even the diode."

Just doesn't seem like you saw a lot of wisdom in the 10 your old document.
Tell me, what part of it do you think is wise?
I didn't morph and I'm not a retard,
I think your losing your mind.
Mike

Do you think the back EMF generated on an unsuppressed 3.3V relay
solenoid coil upon excitation removal is -750 Volts?


It's not beyond the realm of possibility.

boB

Given the 12 V figures, and the difference in core mass between the two
form factors, I would say that it is decidedly easy to contend that it IS
beyond the realm of possibility to get that level of flyback from a 3.3
Volt stimulus into a tiny, low mass, low turns count, open ended coil..

Who cares?
Just use the standard RC snubber across the coil; 100 ohms should be
fine.

You should learn to read... it's a custom chip issue. I posted a link
to a proper solution.

BTW, 100 Ohms and a coil current of 33mA would produce 6.6V (net, 3.3V
supply) on the drain, exceeding the 5.5V maximum operating rating.

...Jim Thompson
100 ohms was a "generic" rough "ballpark" value which you should very
well know; so if you dislike 100 ohms, then use 50 ohms already!

Diode+resistor or diode+zener are both a lot faster than just a diode.

Or even just a series or shunt resistor, if you can spare the power.

No clamp at all is even faster; just let it fly up and ring, with
suitable precautions.

The untimate would be to apply a large reverse voltage to the coil
until the current goes to zero. That's what happens automagically in a
linear amp driving an inductive load with current feedback.

you can probably come close to that with just the right RC snubber
(just enough for critial damping)

Since capacitors larger than around 30pF are forbidden, I chose my
approach... which works perfectly, by the way ;-)

Yes.

Backing up a few threads... MOST IC designs are standard product...
you know, all that stuff from Linear, National, Fairchild, TI. There's
only a handful of us doing custom, particularly custom analog or
analog/mixed-signal.

Where are your relay coil driver stimulus release spike abatement ideas
at then, asswipe (slings **** your way)? I fart in your direct
direction!

That was three fecal references in 24 words, 12.5%. I think 10% is the
threshold for nether-region obsession.

John

Don't count 'em up and attribute them to a single person, you **** for
brains dumb****!

I made ONE reference (slings **** your way). Not that a retarded wuss
like you could grasp the fact that he wrote (ducking), much less what it
refers to.

An "asswipe" is a wipe for the ass. There is no fecal reference there
at all. The fart reference is "bathroom humor" not fecal, you pathetic,
cringing, wussified milksop.

So **** OFF yet again with your retarded claims that you make
incessantly. You're a goddamned idiot, as well as being stupid for
thinking that some number validates your retarded claim.

It doesn't get any more pathetic than that, Johnny. Somebody should
drop a burning paper bag on your doorstep.

"I think 10%... blah blah blah." You're an idiot, Johnny. We only
needed ONE occurrence of your stupid **** in the groups to validate that
FACT. Give it up, you **** for brains dumb****.

It's like this... If I am "obsessed with it", then you are made of it.
So make up your mind. If your claim is valid, you are made of it. If
you are a lying idiot that has zero psychological knowledge, much less
qualifications, then... you are STILL made of it.

You lose, either way, Johnny boy.

I think most people derive more enjoyment from the input end of their
digestive system than from the output. Buy hey, whatever turns you on.

John


AGAIN, you retarded ****, NOBODY said a goddamned thing about enjoying
ANY ****ing input(s) or output(s) of any kind on any part of anyone, you
goddamned won't ****ing let it go sub-human pond scum!

You do know what pond scum predominantly is, right?


Algae. Small plants powered by sunlight.

John


No, dumbass. Algae is algae. Pond scum is fish feces. It is at the
bottom of the pond. The algae is up at the surface depths.

ALL plants are powered by sunlight. D'oh!

PS. A diode is the slowest dropout time listed.

Note also that the diode is also the best at suppressing the spike.

Note also that UNsupressed is the only way to get it fast. ALL the
other methods slow it.

Note that you contradicted yourself.

Note also that you are an ignorant berk.

Note also that you have no clue as to how inductive circuits behave.

ALL of the other methods violate his 'issues' list.

In many cases, that is the most important constraint (the spike).
Note also that all the figures are for 12V relays, which are not in much
use on modern low voltage circuit designs these days.

I am quite certain that any 3.3V relay you choose to examine will prove
to be faster than any of the numbers that more than 10 year old document
measured. Even the diode.

And he (or she) doesn't even know what s/he's talking about. First,
"algae" is plural, i.e., algae ARE algae.

And apparently he/she is unaware of the simple fact that "scum" is
what floats to the top, much like the political system. :-
