Abstract (en)
[origin: DE19531899A1] An electronic device (1) has an acceleration values sensor (2) and a controller (3) connected to the sensor (2). The controller (3) drives switching elements (S1, S2) that form a series circuit that includes at least one ignitor (5). When the switching elements (S1, S2) are triggered, a current is applied to the ignitor (5). The current flows at the same time through the resistance (RM) mounted in series and at which a voltage drop results that is evaluated by a comparator (7). The clock ratio of the current drive is modified depending on the intensity of the current that flows through the ignitor (5).
