Circuit arrangement having a load transistor and a voltage limiting circuit and method for driving a load transistor The present invention relates to a circuit arrangement having the following features: a load transistor (T) having a control connection (G) and a first and second load connection (D, S), a drive connection (IN) coupled to the control connection (G) of the load transistor (T) and serving for the application of a drive signal (Sin), a voltage limiting circuit ( 10 ) connected between one (D) of the load connections and the drive connection (G) of the transistor, a deactivation circuit ( 20 ) connected to the voltage limiting circuit ( 10 ) and serving for the deactivation of the voltage limiting circuit ( 10 ) in a manner dependent on a deactivation signal (S 22; S 23 ), which is dependent on a load current (Id) through the load transistor (T) and/or on a drive voltage (Vgs) of the load transistor (T). The invention furthermore relates to a method for driving a load transistor.
