Abstract: A passenger protection device of an automobile is triggered when a testable acceleration switch supplies a switch signal and an electrically controlled switching device is actuated by a control circuit depending on a collision. Actuation of the switching device is prevented on a triggering circuit side by a blocking device so that the passenger protection device is not triggered as a result of faulty control switching during testing of the acceleration switch.

Abstract: A method of diagnosing an actuator includes supplying a predeterminable amount of energy to an actuator through a charge-reversal circuit. Faulty functional statuses of the actuator and its supply lines and/or its drive circuits, short- or long-term interruptions, short-circuits within the actuator or its supply lines, or excessively low capacitance values may be deduced from a discrepancy between reference values and determined variables including actuator voltage, actuator current, and actuator charge. A short-circuit of an electrical connection within the actuator or an electrical connection between the drive circuit and the actuator can be deduced if the actuator voltage is less than a lower voltage value. An interruption in the electrical connection within is the actuator or an electrical connection between the drive circuit and the actuator may be deduced if an actuator peak current is less than a lower current value. An apparatus for performing the method is also provided.

Abstract: A circuit includes a programmable element having conductor track resistance that can be permanently altered by an electric current. The circuit also has a switchable element for receiving a control signal for programming the programmable element. The programmable element and the switchable element are connected in series between two supply potentials. The programmable element can have an electrical fuse. The input of a read-out circuit is connected through a protective circuit to the circuit node between the programmable element and the switchable element. The protective circuit serves for limiting the voltage potential at the input of the read-out circuit during a programming operation. The circuit elements of the read-out circuit can thus be dimensioned in an area-saving manner. The protective circuit also can include a diode having an anode connected to the input of the read-out circuit and a cathode connected to a third supply potential.
