Hello,
I have the below circuit to control a solenoid with a micro-controller.
The solenoid will be drawing about 1.2A and I will also be measuring the current drawn.
My question is with the gate driver for Q2, I think I will need a zener or a divider with maybe 2 1K resistors so I don't blow the gates of Q2 and Q3.
Also on D2, D3, D6, not sure if D6 and D3 and really necessary here. Maybe it would be fine with just D2 as flyback. What's the purpose of D3?
