The present invention relates to a reverse voltage protection circuit which connects a semiconductor element to a ground terminal without connecting to an additional circuit for preventing a reverse voltage, thereby preventing a reverse voltage. According to an embodiment of the present invention, the reverse voltage protection circuit comprises: a regulator connected between a power source terminal and a ground (GND) terminal; a first semiconductor element connected between a GND terminal of the regulator and the GND terminal; an inverter connected between the power source terminal and the GND terminal; and a second semiconductor element connected between a GND terminal of the inverter and the GND terminal, wherein the first semiconductor element and the second semiconductor element are connected to the GND terminal.

    본 발명은 역전압을 방지하기 위한 별도의 회로를 연결하지 않고 반도체소자를 그라운드단에 연결하여 역전압을 방지하는 역전압 방지 회로에 관한 것이다. 본 발명의 실시 예에 따른 역전압 방지 회로는 전원단과 그라운드(GND)단 사이에 연결되는 레귤레이터와, 상기 레귤레이터의 그라운드단과 상기 그라운드단 사이에 연결되는 제1 반도체소자와, 상기 전원단과 상기 그라운드단 사이에 연결되는 인버터와, 상기 인버터의 그라운드단과 상기 그라운드단 사이에 연결되는 제2 반도체소자를 포함하고, 상기 제1 반도체소자 및 상기 제2 반도체소자는 상기 그라운드단에 연결된다.
