  • ABNORMALITY DETECTION DEVICE FOR DETECTION CIRCUIT AND ELECTRIC CIRCUIT, AND DETECTION SYSTEM AND ELECTRONIC SYSTEM WHICH USES ABNORMALITY DETECTION DEVICE
    Publication number: 20120035824
    Abstract: In an electric circuit whose behavior is changed corresponding to a peripheral environment, an abnormality detection device can surely detect abnormality in the electric circuit even in a state where a value of the peripheral environment cannot be specified. An abnormality detection device according to the present invention detects abnormality in a detection circuit (112) which detects a specific kind of physical quantity. The abnormality detection device includes an abnormality detection part (220a) which changes magnitude of a power source voltage (Vcc?) which is supplied to the detection circuit (112), and detects abnormality in the detection circuit based on an output signal (Vo2) from the detection circuit at a power source voltage (Vc2) after the change.
