发明名称 MOTOR DRIVE DEVICE, MAGNETIC DISK STORAGE DEVICE, AND ELECTRONIC APPLIANCE
摘要 A motor drive device has a driver circuit generating an output current for a motor and a control circuit controlling the drive circuit. The control circuit, when switching the driver circuit from a PWM-driving state to a linear-driving state, controls the timing of the switching such that the path of the output current does not change between before and after the switching, and in addition, in the middle of the switching, switches the driver circuit to a high-output-impedance state momentarily.
