Abstract: A method for ascertaining an inner resistance of a supply network for supplying energy to an occupant protection system of a vehicle. The occupant protection system includes a charging unit connected to the supply network using a primary interface and to an energy buffer store using a secondary interface for the temporary storage of energy for activating occupant protection devices system and for supplying the system after being separated from the supply network. The method includes impressing a first charge current value at the secondary interface, and a first current/voltage at the primary interface during the impression. Further, a second, different, charge current value is impressed at the secondary interface. The method also includes determining a second current/voltage at the primary interface during the impression, and ascertaining the inner resistance of the supply network, using the detected first current and second current and/or the first voltage and the second voltage.

Abstract: An energy supply unit for supplying a consumer, includes an energy store to supply electric when the consumer is decoupled from an energy supply network. The energy supply unit includes an energy supply controller having an input coupled to the energy store, via a diode, for receiving electric energy and an output for delivering electric energy, and a monitoring unit for outputting a monitoring signal, configured to set the monitoring signal to an active state when an output voltage between the output and a reference potential is lower/greater than a predefined activation threshold value, the monitoring unit configured, when an excessively low input voltage is identified between the input and reference potential of the controller, especially paired with an excessively low output voltage, the monitoring signal is switched to the inactive state when the input voltage is above a reset threshold and the output voltage is within the monitoring band.

Abstract: A step-down voltage regulator. The step-down voltage regulator includes a configurable integrated switch circuit, which includes a configurable analysis and control unit, a configurable actuation circuit, compensation circuit, and controllable semiconductor switch, and includes an external wiring with different components. The wiring is electrically connected to connections of the integrated switch circuit. A feedback signal representing an output voltage that can be tapped at an output of the integrated switch circuit is fed back to the analysis and control unit, which generates a switch signal in combination with the actuation circuit based on the feedback signal and outputs it to the controllable semiconductor switch such that a closed control loop for regulating the output voltage is produced from an input voltage applied to an input of the integrated switch circuit. The output voltage maximally has the voltage level of the input voltage.
