Abstract
A circuit for providing a polarity sensing power and signal interface. The circuit includes a rectifier circuit operably connected a two line system wherein the rectifier circuit is comprised of at least two transistors for providing the circuit with a low-impedance path to ground and providing the circuit with a polarity insensitive output. Capacitors may be operably connected to transistors in the rectifier circuit to keep the transistors turned on when a low voltage is applied to the rectifier circuit.
