三相电机驱动光盘 Three-phase motor driver for CD-ROMs
System Motor Driver ICs for CD/DVD Players
● Description
ROHM’s spindle motor drivers incorporate the 3-phase full-wave pseudo-linear drive system, BA6664FM and 180 ° electrifying direct PWM drive systemBD6671FM.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.
