    摘要： A circuit configuration providing a diagnostic signal for a power switching device which switches a load has a test circuit, a filter device, a validation device, and a coding device. The test circuit tests the power switching device and generates error symptoms for characterizing error types of different priorities. The filter device, depending on an activation signal activating the power switching device, provides a validity signal for the generated error symptoms. The validity signal specifies the validity of the corresponding error symptom in each case. The validation device validates a generated error symptom depending on the associated validity signal in each case and validates the validated activation signal and from this generates a group of is states and the associated complementary states. The coding device codes the states and complementary states depending on the priorities of the error types assigned to the states and complementary states. The diagnostic signal is formed from the coded states and complementary states.

    摘要： A control circuit for a switching device with a relay and a switch. The control circuit is configured in such a way as to produce a hold signal for a predetermined period of time when a start signal is supplied thereto. The control circuit is also configured in such a way as to produce the hold signal for the predefined period of time independently of the course of the start signal during the predefined period of time. The control circuit is also configured in order to activate a switch output when at least one of two conditions is met. The switch enables the relay to be supplied with current when the switch output is activated, otherwise it prevents the relay from being supplied with current.

    摘要： A method and a circuit are provided for the continuous detection of a line break in a full bridge controlling an inductive load. When the full bridge is switched off or on, a pre-determinable switching device of the circuit is switched first, and then a potential applied to a connection between the switching device and the load is tapped. The tapped potential is then compared with the ground potential when the switching device is connected to the supply potential, or with the supply potential when the switching device is connected to the ground potential. A line break is then determined when the two compared potentials are not different in the free running state thereof.

    摘要： A circuit with switchable functionality has a first integrated circuit, which has, in a first operating mode, full functionality and which has, in at least one other operating mode, a functionality which is reduced in comparison with the full functionality. The circuit further has an output terminal to which a coupling element can be coupled, an identification device which identifies whether a first supply potential has been applied to the output terminal via the coupling element and in this case produces a status signal with a first value and otherwise produces a status signal with a second value, a setting device, which sets the full or reduced functionality as a function of the value of the status signal in the first integrated circuit. The invention also relates to an electronic component having such a circuit arrangement.
