Hey everyone,
I have a 0-5v+ signal (from a non inverting op amp) going into a comparator with a vref of about 5v from a 5.1v zener.
I want the comparator to latch up when the input signal goes over 5v and keep latched until the circuit is powered off.
I figured I would need some kind of positive feedback but i'm really rusty with that.
Btw the comparator has an open collector output (lm239).
Thanks in advance.
