PURPOSE: A over voltage protection circuit including an electronic control unit and MDPS(motor driven power steering) ECU(electronic control unit) having the circuit are provided to reduce the number of components by omitting and interface circuit, and a pre driver IC and a software. CONSTITUTION: DC power is inputted to a first input terminal(IN1). Reference power lower than the DC power is inputted from a second input terminal(IN2). A current path connects the first input terminal and the second input terminal. An input circuit(110) transmits the DC power to a rear end. An output circuit(120) converts the DC power to an output signal and outputs.
