Abstract
A circuit that includes a bridge rectifier configured to convert a sensed input signal into a rectified output signal and a regulator configured to convert the rectified output signal into a voltage source signal. The circuit further includes a variable period timer configured to be powered by the voltage source signal and to convert the rectified output signal into a low duty cycle timer signal in which 50% is a low duty cycle and the low duty cycle timer signal has a frequency that is correlated to an input voltage level of the sensed input signal, wherein the voltage sensing circuit is configured to operate on input voltage levels of sensed alternating current (AC) and direct current (DC) input signals over one or more determined dynamic ranges.
