Claim:
1. An integrated circuit formed into a single chip, for a control system of a rotating electric machine that is electrically connected to a power conversion circuit, the integrated circuit comprising: a drive signal generating unit that is incorporated in the integrated circuit, which generates drive signals for switching elements configuring the power conversion circuit; a monitoring unit that is incorporated in the integrated circuit, and monitors a microcomputer that is provided separately from the integrated circuit and calculates generation information that is information used to generate the drive signals, the monitoring unit determining whether or not an abnormality has occurred in the microcomputer; and an angle converting unit that is incorporated in the integrated circuit, which receives an output signal from an angle sensor that outputs the output signal based on a rotation angle of the rotating electric machine, the angle converting unit converting the output signal of the angle sensor to rotation angle information of the rotating electric machine, wherein the drive signal generating unit is configured to
