Abstract
An alarm output circuit can cope with simultaneous generations of a plurality of alarm factors based on alarm signals output from one output terminal. The alarm output circuit notifies externally of generations of alarm factors in an intelligent power module. A digital/analog converter, into which digital data indicating the presences and absences of generations of the alarm factors is input, outputs corresponding voltages. A voltage control oscillator outputs a signal of a frequency corresponding to an output voltage of the digital/analog converter.
