1. An electronic device for actuating a passenger-protection system, comprising:

  • at least one acceleration sensor generating a sensor signal;

    a control unit for analyzing the sensor signal;

    at least one squib coupled to the control unit and being traversed by a current;

    at least one restraining device being selectively actuated by the control unit using the at least one squib;

    a current detecting arrangement detecting a value of the current flowing through the at least one squib and comparing the value of the current to at least one predetermined threshold value; and

    a current control arrangement coupled to the current detecting arrangement controlling a clock pulse duty factor of the current flowing through the at least one squib.
