Abstract

The present invention relates to a switch relay device, and more particularly, to a switch relay device which is used as an electronic relay that drives electronic components mounted on an automobile. The switch relay device includes: a switching control unit for determining a duty value depending on the kind of a control input signal inputted thereto and generating a first switching control signal and a second switching control signal whose phases are opposite to each other; a switching drive signal generation unit for generating a switching drive signal through R-C charge and discharge in response to the first switching control signal and the second switching control signal applied thereto from the switching control unit; a load output signal generation unit for receiving the switching drive signal from the switching drive signal generation unit and outputting a load output signal; and a constant voltage unit connected to a battery disposed in a vehicle to supply power to the switching drive signal generation unit and the load output signal generation unit and configured to provide a constant voltage to the switching control unit.
