Abstract
In an integrated circuit formed into a single chip, a drive signal generating unit generates drive signals for switching elements of a power conversion circuit. A monitoring unit monitors a microcomputer that calculates generation information that is information used to generate the drive signals, and determines whether or not an abnormality has occurred in the microcomputer. An angle converting unit converts an output signal of an angle sensor to rotation angle information of a rotating electric machine. A drive signal generating unit generates the drive signals for controlling driving of the rotating electric machine based on the generation information and the rotation angle information when the monitoring unit determines that an abnormality has not occurred in the microcomputer, and generates the drive signals based on the rotation angle information, without using the generation information, when the monitoring unit determines that an abnormality has occurred in the microcomputer.
