Hi all, I have a couple scenarios, and need to decide on which component best suits my need: I have two solenoids that I need to drive with 12V, based on a 5V uC signal. Simple on/off switch. I'm very new to using MOSFETs, so I'm not sure if you can drive 12V with a 5V signal (which would have a Vbe ~ 6.5V in a BJT, and would blow it up). Do I need a relay/optocoupler here, or will a Power MOSFET be able to handle it? max 1A, 12V. Also, I have a PWM signal that is potentially noisy, anywhere between 15-250Hz. I'm pretty sure an optocoupler would be most appropriate here? How would a MOSFET compare?
