Abstract
A semiconductor module including a first switching device coupled to a first line, a terminal, at which a first voltage corresponding to a first current flowing through the first switching device is generated, coupled to the first switching device, a second switching device coupled to the first line for allowing a second current corresponding to the first current to flow therethrough, a voltage generation circuit configured to apply, to a second line, a second voltage lower than a power supply voltage, a resistor, across which a third voltage corresponding to the second current is generated, coupled between the second switching device and the terminal, a reference voltage circuit coupled to the terminal for generating a fourth voltage, and a comparator circuit coupled between the first and second lines, for determining whether the first switching device is in an overcurrent state based on a comparison between the third and fourth voltages.
