Patent number: 7932622Abstract: 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.Type: GrantFiled: September 29, 2006Date of Patent: April 26, 2011Assignee: Infineon Technologies AGInventors: Giorgio Chiozzi, Alberto Flore, Joachim Glaeser, Alberto Gola, Michael Lenz, Nicola Macri, Salvatore Piccolella
