知駆動装置。 When the switch circuit of the load driving means is turned on by the drive signal, load current is supplied from the power supply to the load, and the state determining means for determining the state of the load detects a shorted state or an open state of the load. and a short detection signal and an open detection signal indicating the state are output from the state determining means, and in the short state and the open state, input of the drive signal to the load driving means is blocked. In the detection drive device, input signals include an electric element connected between the power supply device and the load, through which a determination current is passed in a specific state of the load, the drive signal, and an input voltage to the load; It is characterized by comprising a logic judgment circuit that judges whether the load is in a normal state, shorted state or open state based on the logic value of an input signal, and a display means for displaying the judgment result of this logic judgment circuit. Load condition detection drive device.
