ABSTRACT:
A circuit arrangement (1) for driving an electrical load (13) comprises a first and a second terminal (2, 3) for feeding a first and a second control signal (S1, S2), a first output (23), to which an electrical load (13) can be coupled, a current source (9), which is coupled to the first output (23), and a control device (5). The control device is coupled to the first and the second terminal (2, 3) and comprises a programming circuit (6) and a trigger circuit (7), which are each coupled on the output side to a control input of the current source (9).
