Circuit arrangement having a power transistor and a drive circuit for the power transistor The invention relates to a circuit arrangement having the following features: a power transistor (T) having a control terminal (G) and also a first and second load path terminal (D, S), the first load path terminal (D) of which is connected to a terminal for supply potential (V1) via an inductance-exhibiting line terminal (1) and the second load path terminal (S) of which serves for connecting a load (Z), and a first drive unit (10) for off-state driving of the power transistor (T) having an output (11) connected to the control terminal (G) of the power transistor (T1), and having a first current source arrangement (Iq1) connected between the output (AK) and a first drive potential (GND), in which case the first drive unit has a second current source arrangement (S2off, Iq2; S2off, Iq2, Iq21), which is connected to the output (AK) and which provides a current (I2; I2, I21) that is dependent on a temporal change in a terminal potential (Vd) at the first load path terminal (D) of the power transistor (T).
