    Hi there....

    I wanted to make a circuit which senses two voltage levels.....If the voltage level is below 43 it gives 1 and if if above 43 and at the same time below 55 it gives 0...Is there any practical comparator available that works at this voltage?

    I thought of connecting a relay and a 43 vol DC battery to the out put of the comparator..How does this idea sound...Need help....Thank you

    Thanks! I actually found a circuit....But the weird problem is that the source that is fed to the comparator is actually a super-capacitor..When it's voltage drops below 43 V I want it to get charged but due to the resistor arrangement as shown in the circuit it should get discharged..So what about it....?
