@Justme It is HK4100F. With 160 Ohm coil resistance (measured) it should be able to draw 31,25 mA at 5V. I'm just assuming the transistor is dead, need to get a new one.

@Justme Sorry if that was confusing. So it seems like the FET is probably damaged, that's why the strange behavior?

@Justme my question is why there is such a small current flowing through the FET. Initially, I have measured the current with a series resistor, and I gradually reduced the resistance to none to see if the current would increase, but it did not.

You might haved just saved me from a ton of headache :D

This works, thanks a lot. You're right that I can't get to 5V, I will just scale down the voltage divider so that maximum measured voltage will be 2.5 V instead of 5 V.

Do I feed the output from the buffer to the second amplifier? What will be the feedback at the second amplifier?

@G36 Perfect, I think this is going to be my go-to simulator now

Seems like the problem was really with the amplifier, after swapping for another one the limiting is working. Thank you.
