Hey all-
I am trying to learn about/build a circuit to control a 2 amp electric motor. Basically I would like the electric motor to be controlled by 12 volt DC pulse width modulation. However, I would like to apply a small digital positive current 5 volt signal to the gate via my arduino digital outputs to the gate to switch off the high amp current quickly.
From my research this looks like I need an exclusive OR gate (XOR). Most of the integrated circuits that I see from Texas Instruments are only rated to control milliamp circuits. I think I could build my own gate out of very large transistors with heat sinks but it sort of seems like overkill for only 2 amps. Is there an easier way to do what I am trying to do? Thanks!
