It's important to understand John, this is only a demonstration of a use of the NCV33361 voltage monitor chip, and the DMG6602 FET pair. It is NOT a valid or certified circuit diagram for wiring. Using LTspice is a very convenient way to verify circuit theory and operation.

In the groups.io 'files' section is folder VoltageMonitorSpice containing the .asc .asy files for the components, and I just added the .asc file for the circuit (voltageMonitor.asc).

There is no .lib file tying them all together.

Try this: Put all the files in one folder on your computer. Open the voltageMonitor.asc file in LTspice...it should show the complete schematic. I believe if the .asc and .asy files for the components are in the same folder as the spice circuit your using (voltageMonitor.asc) LTspice will "figure it out" and use the origin folder to find the component models.

Otherwise, you are going to have to recreate the schematic, download the spice files for the NCVxx and DMGxx components and create the components models in the LTspice "autogenerated" folder. This is easy to do...just confusing.

I do not like this groups.io method of having to "add" folders and files to an obscure depository somewhere "out in the cloud."...it is so much easier to simply attach a file using normal email...so if you want to continue on this path to test and simulate the voltage monitor and FET switchs...let's take it to normal email. I am good in the FCC database as WA7LGY.?
