I did .include "the file path to the mod file" but it says I need to right click a general part and include the subcircuit name for the value and erase spice model. Every time I put a generic part on

Dave, thanks for the advice. The ramp down is not needed indeed. Anyway, the original model of TLV1805 is a nice find. Jurek From: <[email protected]> on behalf of "Bell, Dave via groups.io"

You’re right - it does work! I found the output voltage curve a little confusing by itself, with the ramp Up and ramp Down. But reducing the output cap to 10u or increasing the load to 100 ohms, it

Is there a circuit for this thread? Ild like to look at it myself when i get home. Yahoo Mail: Search, Organize, Conquer

I can imagine that crowbar is much better, but I would not be afraid about transients. This chip is extremally fast, a few ns. So – as you said – the TLV1805 is made for this purpose. Jurek From:

I understand that overvoltage protection (OVP) must be a very simple and reliable circuit. I've had a lot of problems with this circuit because sudden load variations can cause transients in the

My Grandfather used to say "make sure it's plumb" meaning make sure it's perfectly vertical. He used to be a handyman and mason.

As much as a defective Power MOSFET can prevent a series-protected voltage limiter, a problem with the crowbar thyristor or its control circuit can defeat its purpose. Nothing is ever perfect.

I would not designate the proposed circuit as an overvoltage protection circuit. At most it's something like a "voltage clipper" or "voltage limiter" for excessive input voltage excursions. Let's

Makes sense. I have everything I need here at work and, at home. I've also done plenty of voltage readings of this device in the past but, like I said, being no one here actual

Ah, yes. I had forgotten that. Thanks. -- Regards, Tony

Hello, I have uploaded circuit that finally works as executed with a good TLV1805 model found online. The problem was the ic. I have used a voltage comparator from the LTSpice library list with an

Oops, I left out a word, two replies back: Andy

I am pretty sure this has nothing to do with version 24.1.1.? I think LTspice has always behaved this way - going back at least as far as LTspice IV and probably earlier. Bee careful here.? When

That can easily be avoided too, if you know you want to. Technically, the "hidden" connection is to a not-hidden pin on the A-device symbol's lower left corner.? If the pin is left floating, which is

Got 'em. Thank you. One more to go.

Just an observation: there are a number of opamp models (for example) that bring a V- (negative supply) pin out of the subckt. The assumption being that the device can be used with V- grounded or with

Doesn't M-W include, 'plumb'? vt:? to investigate deeply, and plumb adj 1: vertical, adj 2: very, completely (mainly US)?
