Abstract: A production method for a micromechanical component for a sensor device or microphone device. The method includes: forming a supporting structure composed of a first sacrificial material on a substrate surface of a substrate with a first sacrificial material layer, a plurality of etching holes structured through the first sacrificial material layer, and a plurality of supporting posts projecting into the substrate; etching into the substrate surface at least one cavity spanned by the supporting structure; forming a diaphragm composed of at least one semiconductor material on or over the first sacrificial material layer of the supporting structure; depositing a layer stack comprising at least one sacrificial layer and at least one counter electrode; and exposing the diaphragm by at least partially removing at least the supporting structure and the at least one sacrificial layer.

Abstract: Measures are described with the aid of which not only a rupture, but also cracks may be detected in the diaphragm structure of a micromechanical component with the aid of circuit means integrated into the diaphragm structure. At least some circuit elements are integrated for this purpose into the bottom side of the diaphragm, i.e., into a diaphragm area directly adjoining the cavern below the diaphragm.

Abstract: A method for activating a rectifier having active switching elements in the event of a load dump, the active switching elements being activated during the voltage clamping in such a way that the clamp voltage in at least one switching branch complies with a signal form predefined as a function of time within at least one half-period of the current to be rectified.

Abstract: A temperature detection device includes a diode and an analog-digital converter. An output voltage signal of the diode is applicable to an input of the analog-digital converter. The temperature detection device is adapted for the purpose of coupling a reference voltage of the analog-digital converter and the diode current of the diode such that effects of variations of the reference voltage or the diode current on the digital output signal of the analog-digital converter are partially or completely suppressed.

Abstract: A device and a method for bidirectional single-wire data transmission of data information between an electronic control unit and at least one peripheral unit. A predefined constant voltage and/or a predefined constant current is applied to a driver device of the electronic control unit to produce voltage-coded and/or current-coded information. The voltage-coded and/or current-coded information is transmitted from the driver device of the electronic control unit to a driver device 30 of the peripheral unit via a single-wire line. At least the driver logic of the driver device and/or the communication logic of the peripheral unit are triggered and powered through the current flow. Information occurring on the peripheral unit is current-coded and/or voltage coded due to the triggering thereof.
