How to protect OpAmp output?
I have an OpAmp which controlls the Gate of a MOSFET.
When the MOSFET dies, sometimes the voltage it's running on (50V) somehow gets to stand over the OpAmp's output which destroys it.
What's the best way to protect the OpAmp from the high voltages that get to stand over the output?
Will a zener do the trick?
Trigger transformer won't be easy to use here because It's a PWM controller so I need nice block waves.
Diode on the output? but won't this be bad for delivering good current to the Gate?
