ABSTRACT:
An integrated power transistor includes emitter or source regions, and a comb-like patterned metal electrode structure interconnecting the emitter or source regions and defining at least one connection pad. The comb-like patterned metal electrode structure includes a plurality of fingers. A current sensing resistor produces a voltage drop representative of a current delivered to a load by the integrated power transistor. The current sensing resistor includes a portion of a current carrying metal track having a known resistance value and extending between one of the fingers and a connectable point along the current carrying metal track.
