Beschreibung
Zusammenfassung:	A disconnection detection circuit (1) includes: a pull-up resistor (103) to which the detection signal (Dd) is fed and which connects a signal line (113c) connected to the wiring cable (12) to a power supply (power supply voltage) (Vdd) or a pull-down resistor which connects the signal line (113c) to a GND; and a voltage clip circuit 105 (105a...) which includes a high-voltage clip circuit (105au...) which is connected between the signal line (113c) and the power supply (Vdd) and which clips the voltage of the signal line (113c) to the maximum specified voltage (Vdm) and a low-voltage clip circuit (105ad...) which is connected between the signal line (113c) and the GND and which clips the voltage of the signal line (113c) to the minimum specified voltage (Vds).
