Control circuit for activation element of motor vehicle occupant protection system has sensor, processing unit, comparator circuit(s), trigger circuit that triggers activation element depending on activation and enabling signals

摘要

The circuit has at least one sensor (10) for detecting an activation event, a processing unit (20) that receives the sensor signal for evaluation and produces a trigger signal (S20) dependent on the evaluation result, at least one comparator circuit (40) and a trigger circuit (30) for connection to the activation element (50), to which activation and enabling signals (S20, S40) are fed and that triggers the activation element depending on the activation and enabling signals.
