1. An actuating device for triggering at least one pyrofuse, the actuating device comprising:
a supply voltage connection for connection to a supply voltage;
at least one triggering output for connecting the at least one pyrofuse and applying a triggering current to the at least one pyrofuse;
a signal input for receiving a triggering signal that indicates a state requiring the triggering;
at least one actuating circuit connectable to the supply voltage connection for providing the triggering current to the at least one triggering output in dependence on the received triggering signal, wherein the at least one actuating circuit comprises a field effect transistor stage for switching the supply voltage through to the at least one triggering output in dependence on the received triggering signal; and
an evaluation circuit for evaluating the received triggering signal that has a flip-flop stage for converting a brief triggering signal pulse into a permanent triggering signal,
wherein the flip-flop stage has a flip-flop element, wherein the flip-flop element comprises an RS flip-flop, and wherein the flip-flop element comprises a supply voltage connection for receiving the supply voltage.
