Abstract
An electronic airbag ignition circuit includes a first and second output for the electrically conductive connection to a first and second terminal of a magnetic actuator. The electronic airbag ignition circuit also includes a first switching element, whose contact-break path is connected in an electrically conductive manner to the first output, and a second switching element, whose contact-break path is connected in an electrically conductive manner to the second output. The electronic airbag ignition circuit includes a second control circuit connected in an electrically conductive manner to a control terminal of the second switching element. The second control circuit is configured to close the second switching element in a first triggering mode for a first predetermined duration and in a second triggering mode for a second predetermined duration that differs from the first duration.
