Description
BD7789RFS are energy-saving, low noise ICs, developed for the spindel motor, actuator coil, tilt coil, stepping motor, and the loading motor drive of the desktop PC/DVD recorder.
A System Motor Driver IC for CD/DVD is a specialized integrated circuit used in optical disc drives (CD and DVD players) to control and drive the various motors involved in the disc reading and loading mechanisms. These motors are responsible for tasks such as spinning the disc, moving the laser assembly, and loading/ejecting discs.
The System Motor Driver IC typically integrates multiple motor driver channels, as well as other necessary control circuitry, making it a convenient and efficient solution for driving the motors in CD/DVD drives.
Features
1. Simple low revolution control with LRPM mode
2. Hall sensors are not required
3. The spindle motor driver archieves a high speed start and driver stability by the drive system of an orginal ROHM.
