@ReverseEMF,The only one getting emotional here is you.Try leaving it out and just discussing the technical details , like the fact that the TC4427 was designed
to drive mosfets. It works fine when used that way.Put 12V on Vdd and drive it with a 5V output from the arduino and you will see 12V on the output.
There is no reason to be so argumentative. No one is being emotional at all.
As has been posted several times 5v is within the operating range of the TC4427 driver. I also had originally posted that I started with a mosfet on the output with 12v on Vdd and it would not turn off the mosfet when switched off. That's why I posted the test circuit above with the LED as a test. If it wont turn off an LED how can I expect it to turn off a mosfet?
I'm thinking that ReverseEMF is the only one here who has actually read the entire thread.
