摘要： A power switch circuit for driving an airbag squib module has a power transistor, a pre-charge capacitance for storing a charge, a charging circuit and a controllable energy-coupling element. The power transistor has a first electrode, a second electrode and a control electrode. A path between the first electrode and the second electrode is connected in series with the airbag squib module between a supply potential and a reference potential. The charging circuit charges the pre-charge capacitance and the charging circuit is therefore coupled with the pre-charged capacitance. The controllable energy coupling element is connected between a first electrode of the pre-charge capacitance and the control electrode of the power transistor. The power switch exhibits a high degree of stability, allows a fast switching of the power transistor and further has an advantageous transient response.

摘要： A regulating system comprises an input terminal for applying an input voltage, and an output terminal for providing an output voltage. A semiconductor element is connected between the input terminal and the output terminal and is operable to regulate the output voltage. A regulating signal generation circuit generates the regulating signal and comprises a current mirror arrangement including a first and second current mirror path, wherein a controlled current source is connected in series to the first current mirror path. The controlled current source induces a first current dependent on one of the output signals in the first current mirror path. A second current through the second current mirror path is dependent on the first current. A splitter circuit conducts the second current to the output terminal or to a reference potential, dependent on a load path voltage applied over the load path of the semiconductor element.
