1路主轴电机驱动器IC 1ch Spindle Motor Driver ICs

System Motor Driver ICs for CD/DVD Players

● Description

ROHM’s spindle motor drivers incorporate the 3-phase full-wave pseudo-linear drive systemBA6859AFP-Y, BA6664FM and 180 ° electrifying direct PWM drive system.Smooth rotation characteristic performance is ensured.

Besides, high torque is provided in a wide output range because the output stage incorporates low-saturation voltage NPN transistors BA6859AFP-Y, BA6664FM and low-power consumption MOSFET BA6671FM.
