Abstract
To fire a firing cap of a vehicle occupant protection system of a motor vehicle, at least two firing capacitors are provided which initially remain connected in parallel at the start of a firing process and are connected in series after expiry of a time interval from the start of the firing process. It is ensured that a firing current which flows across the firing cap is always of a sufficient magnitude and at the same time initial power losses are avoided.
