Abstract
A system for activating a triggering element for a passenger protection unit includes: a high-side control circuit establishing a first connection from an energy source to the triggering element, a low-side control circuit establishing a second connection of the triggering element to ground, and a regulating device regulating a firing current for the triggering element). A firing mode is selected as a function of a connected triggering element. In a first firing mode, a first firing current having a first time characteristic is generated for an ohmic triggering element, and in a second firing mode, a second firing current having a second time characteristic is generated for an inductive triggering element.
