ABSTRACT:
A circuit for detecting voltage states output from a voltage generating engine has a first connection point connecting the circuit to a voltage output of the engine, a second connection point connecting the circuit to electrical ground and a digital output signal port for providing binary output values. The circuit detects voltage levels ranging above and below a nominal voltage level and assigns binary values to the detected states, the values used as instruction to a device coupled to the circuit.
