W wireengineer New Member Jul 30, 2010 #1 Hi all! Im trying to find a circuit that monitors a 12v supply and will give an indication (audio or visual) when the voltage drops to <10v. I have found this circuit..... Circuit - 9v Battery Voltage Monitor using a LTC1440 comparator - Circuits designed by David A. Johnson, P.E. but how could i change the supply and cut off values? Thanks in advance, im looking forward to all of your ideas!!!
