Abstract:
1. A circuit arrangement for protection against electrostatic discharges, comprising a shunt device connected between a first and a second terminal of the circuit arrangement and having a control input, via which a conductivity of the shunt device is controllable; a trigger element having a trigger output for issuing a trigger signal in dependence on a voltage between the first and the second terminals of the circuit arrangement; and an interruption unit comprising a series circuit having a first transistor and a second transistor, the interruption unit being controllable via a deactivation input by a supplied deactivation signal, the interruption unit being connected on an input side to the trigger output and on an output side to the control input; wherein a connecting point between a gate terminal of the first transistor and a gate terminal of the second transistor forms an activation input for supplying the deactivation signal.
