5ch System Motor Driver ICs

5ch system motor driver of the ROHM is the most standard system motor driver the best for the drive of an indispensable actuator for the disk drive of CD / DVD, the thread, the loading, and the spindle motor. The type where the super-silent spindle drive is achieved by an original PWM drive and the type where a high-speed drive of the actuator is achieved by the current return drive adoption are collected.
