Abstract
A rotation detection device includes a rotation detection circuit, a step-up power supply circuit, a step-down power supply circuit, a first power supply path, and a second power supply path. The rotation detection circuit is configured to detect a rotation number of a motor that generates a torque applied to a steering mechanism of a vehicle, based on an electric signal. The electric signal is generated according to a rotation angle of the motor that is acquired through an in-vehicle sensor.
