Abstract

A device includes a leadframe having a diepad and leads, a compound semiconductor chip arranged over a first surface of the diepad and including gate, source electrode and drain electrodes, and an encapsulation material covering the compound semiconductor chip and diepad. A second surface of the diepad opposite the first surface is exposed from the encapsulation material. The device also includes a first lead of the leadframe electrically coupled to the gate electrode, a second lead of the leadframe electrically coupled to the source electrode, a third lead of the leadframe electrically coupled to the source electrode, and a fourth lead of the leadframe electrically coupled to the drain electrode. The third lead is configured to provide a sensing signal representing an electrical potential of the source electrode to a gate driver circuit. The gate driver circuit is configured to drive the gate electrode based on the sensing signal.
