Abstract: A surge protection circuit that can be used, in particular, for monitoring and protecting a diagnostic interface, such as, for example, the SAE J 1708 diagnostic interface. A shared surge detection device, which generates a switch-off threshold voltage, receives the input signals of two input lines with the help of a diode combination. When a surge condition occurs in at least one input voltage, the surge detection device places one of the MOS field-effect transistors connected into the input line in a non-conductive state so that a high-resistance interrupt of the input signal lines, connected on the output side to an integrated interface circuit, is produced. In normal operation, i.e., when no surge condition occurs, the two MOS field-effect transistors produce a low-resistance, i.e., basically no-loss, conduction of the input signals in both directions.

Abstract: An apparatus for monitoring at least one sensor which has at least two terminals comprises first switching means and switchable means. A voltage can be applied to the first terminal of the sensor by actuation of the first switching means and a current can be established through the sensor by actuation of the first switching means and the switchable means. The apparatus also includes an analysis circuit with which at least peak voltage values can be determined from the signals generated by the sensor and conveyed to a calculation unit. Also connected to the sensor is a voltage divider which generates a signal which is also conveyed to the calculation unit. As a function of the actuation of the first switching means and switchable means, it is possible in the calculation unit, based on the peak voltage values conveyed to it, to identify a first faulty behavior of the sensor and to determine the resistance of the sensor.
