Hello all. I need a circuit that will provide an output high when the temperature is sensed to be say 160 degree F, but not turn off (go low) till the temperature drops back to say 130 degrees F. I found the LM56 ic and and built it 3 times, still can not get it to work. Rather not use the LM56 anyway, tooooo small when you have 10 thumbs as as I do. As for the switching, I have a circuit that will respond nicely to logic level output of such a circuit.
There are plenty of fan control ckt's, but they all turn on at threshold and off when dropped below threshold. I want it to stay going till a lower temp is reached.
All suggestions will be considered and appreciated.
