ABSTRACT:
A power semiconductor device constituted of a MOSFET incorporating a current detecting function for detecting current making use of a voltage drop developed across a channel resistance in which variations in the channel resistance due to its temperature and the gate voltage are compensated for and thereby highly accurate current detection is achieved.
