Abstract

The present invention relates to a circuit arrangement having the following features: a load transistor having a control connection and a first and second load connection; a drive connection coupled to the control connection of the load transistor and serving for the application of a drive signal; a voltage limiting circuit connected between one of the load connections and the drive connection of the transistor; and a deactivation circuit connected to the voltage limiting circuit and serving for the deactivation of the voltage limiting circuit in a manner dependent on a deactivation signal, which is dependent on a load current through the load transistor and/or on a drive voltage of the load transistor.
