Electronic airbag - ignition circuit with a variable ignition current duration

摘要

It is an electronic airbag - ignition circuit (60) is described, which a first and a second output (15, 16) for electrically conductive connection with a first and a second connection of a magnetic actuator (50) comprises. Further comprises the electronic airbag - ignition circuit (60) a first switching means (1), the switching path of an electrically conductive manner, with the first output (15) is connected, as well as a second switching means (2), the switching path of an electrically conductive manner, with the second output (16) is connected. In addition, the electronic airbag - ignition circuit (60) a second electrically conductive with a control terminal of the second switching means (2), which is connected to the second drive circuit (17) on. According to the invention, the second drive circuit (17) is configured to control the second switching means (2) in a first release - mode for a first predetermined duration and in a second release - mode for a second, from the first duration of different, predetermined duration to close.
