I'm trying to drive a 12v (14W) solenoid and have problems figuring out the components for the driving circuit.
The solenoid draws about 1.166A and the MCU is being operated at 3.3V.
I've seen many driving circuits and they all look something like this:
- What datasheet parameters should I look for when designing this circuit?
- Is the IRF530PBF-ND a suitable MOSFET for driving this solenoid?
Also, how do I calculate R1's value?
I don't want to blindingly copy a circuit that may or may not work, I want to understand it.
Thank you so much in advance!
