Abstract
Lighting and surge protection circuitry for protection of a differential pair includes a diode bridge circuit having a first pair and a second pair of connections to the diode bridge circuit, with the first pair of connections configured to be coupled to a pair of differential inputs of a functional circuit and a first diode coupled between the second pair of connections; and second and third diodes coupled between the first pair of connections and ground. The lighting and surge protection circuitry also includes a diode pair coupled between an output of the functional circuit being protected and power and ground terminals and a small resistance in series with the output of the functional circuit.
