I simulated this circuit in Tina and it seems to be fine but I was wanting to ask if there is anything fundamentally wrong with it. The output is doing exactly what I want it to do but if there is a simpler or better approach I would appreciate the feedback. I tried to model it with a single supply, +24 VDC would be ideal, but I couldn't get the off state was a little over 1V. I would like to do this with the minimum number of components.
