A circuit arrangement for controlling load current of a power MOSFET wherein the load is connected at the source terminal includes a second FET having a defined threshold voltage connected with its drain-source path inserted between the gate and source of the power MOSFET. A third FET connects the gate terminal of the second FET to the drain voltage of the power MOSFET when the power MOSFET is in the conductive condition. When the drain-source voltage of the power MOSFET becomes higher than the threshold voltage of the second FET, the second FET becomes conductive and drives the gate-source voltage of the power MOSFET down.
