Abstract

A method for disconnecting at least one ignition output stage for a squib of a pyrotechnic protection device for a vehicle. The method includes a step of setting an activation signal at an activation level when an amperage of the trigger current for the ignition output stage exceeds a predefined current threshold value, a step of determining a period of time during which the activation signal is set at the activation level, and also a step of supplying a switch signal for disconnecting the ignition output stage, as a function of a comparison of the period of time with a predefined minimum current flow duration.
