ABSTRACT:
A detection part (B), of a disconnection detection apparatus (1A), detects an open destruction of a detection resistor. An emitter of a transistor (Q5) is connected to an upstream end of a detection resistor (R1) through a diode (connected forward) (D2). A base of the transistor (Q5) is connected to a downstream end of the detection resistor (R1) through a resistor (R8). A collector of the transistor (Q5) is connected to an upstream side of a resistor (R4) of a determination part (3). In the detection part (B), the transistor (Q5) is turned on and off according to the difference in the potential between both ends of the detection resistor (R1). In an open destruction detection state, generated when the transistor (Q5) is ON, electric current supplied by the power supply4is fed to the determination part (3) through the transistor (Q5) as a detection result indicating that an open destruction has occurred.
