Integrated Circuit

Abstract

An integrated circuit having a housing in a control unit provides at least two voltage levels, has a watchdog for monitoring a processor, performs an evaluation of at least one acceleration signal to enable at least one ignition output stage, and has at least one first interface for connecting to at least one sensor situated outside the control unit.

1 - 6 . (canceled) 
   
   
       7 . An integrated circuit in a control unit, comprising:
 a watchdog for monitoring a processor; and   at least one first interface for connecting to at least one sensor situated outside the control unit;   wherein the integrated circuit provides at least two voltage levels, and performs an evaluation of at least one acceleration signal derived from the at least one sensor to enable at least one ignition output stage of the control unit.   
   
   
       8 . The integrated circuit as recited in  claim 7 , further comprising:
 at least one second interface for connecting to at least one of an additional sensor and an additional control unit.   
   
   
       9 . The integrated circuit as recited in  claim 7 , wherein the watchdog includes three stages.
