Abstract
One or more additional sense terminals are added to discrete semiconductor packages, assemblies and semiconductor modules, including power semiconductor modules, to sense accurately the voltage between the gate and emitter/source of voltage-controlled chips, inside the package, assembly or module.
Claims5
A semiconductor package, comprising:
- a single controllable power semiconductor die embedded in a molding compound, the power semiconductor die comprising a gate pad, an emitter/source pad and a collector/drain pad;
- a first terminal protruding from the molding compound and electrically connected to the gate pad of the power semiconductor die;
- a second terminal protruding from the molding compound and electrically connected to an additional gate pad of the power semiconductor die;
- a third terminal protruding from the molding compound and electrically connected to the collector/drain pad of the power semiconductor die;
- a fourth terminal protruding from the molding compound and electrically connected to the emitter/source pad of the power semiconductor die;
- and
- a fifth terminal protruding from the molding compound and electrically connected to the emitter/source pad of the power semiconductor die,
- wherein the second terminal and the fourth terminal are configured to carry just a current which is necessary to sense a gate-to-emitter/source voltage of the power semiconductor die,
- wherein the power semiconductor die comprises an integrated gate resistor in series with a gate of a power transistor,
- wherein the additional gate pad is electrically connected to a node between the gate of the power transistor and the integrated gate resistor.
