Abstract: A control device for a personal protection system. The system includes at least one main processor, to generate and output at least one trigger signal for at least one trigger element of a personal protection device of the personal protection system as a function of trigger-relevant information, a central safety circuit with an auxiliary processor, to generate and output at least one enable signal for the at least one trigger element of the personal protection device as a function of the trigger-relevant information, an integrated main system circuit, to generate and output, as a function of the at least one trigger signal and the at least one enable signal, at least one actuation signal for triggering the at least one trigger element of the personal protection device, and at least one control device data bus, via which the main processor communicates with the other components of the control device.

Abstract: A method for operating a vehicle electrical system that is provided for supplying at least one restraint system. In the method, in addition to monitoring the vehicle electrical system voltage, at least one further indicator is monitored as an indicator. A critical supply state of the restraint system is detected by evaluating these indicators and the efficiency of the used DC voltage switching converters is reduced by at least one measure, so that a supply current for at least one restraint system is reduced by the at least one restraint system. A release condition is requested prior to implementing the at least one measure.

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.
