System Motor Driver ICs for CD/DVD Players

● Description

ROHM’s spindle motor drivers incorporate the 3-phase full-wave pseudo-linear drive system(BA6859AFP-Y, BA6664FM) and 180 ° electrifying direct PWM drive system(BD6671FM).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).
