Why a newer 8 pin microprocessor? Why not use an older 4 pin relay with the coil going from your hot lead to your common ground. When the voltage drops too low, the relay opens and disconnects the circuit. You sound like a doctor. Make it more complicated and you can charge more money. (Sorry. No offence meant. The devil made me say that.) Thought for the day: Why do seagulls fly over sea? Because if they flew over the bay, they would be called 'bagels'.
