System Motor Driver ICs for CD/DVD Players 1ch Spindle Motor Driver ICs No.10011EAT03 BA6859AFP-Y,BA6664FM,BD6671FM Description ROHMs 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). Features 1) 3-phase full-wave pseudo-linear system (BA6859AFP-Y, BA6664FM) 2) 180 electrifying direct drive PWM system (BD6671FM) 3) Power saving, TSD (thermal shutdown) functions built in 4) Current limiting, Hall bias circuit built in 5) FG output built in 6) 3-phase component FG output built in (BA6664FM, BD6671FM) 7) Circuit direction detection function built in (BA6859AFP-Y, BA6664FM) 8) Reverse rotation prevention circuit built in 9) Short brake pin built in (BA6859AFP-Y, BA6664FM) 10) Brake mode selection pin built in (BA6859AFP-Y, BD6671FM) 11) Supports DSP 3.3 V Applications Used for car, CD and DVD players incorporating changer function Absolute maximum ratings (Ta=25) Ratings Parameter Symbol Unit BA6859AFP-Y BA6664FM BD6671FM Applied voltage V 7 7 7 V CC Applied voltage V 15 15 15 V M Applied voltage V - - 20 V G 1 2 2 Power dissipation Pd 1450* 2200* 2200* mW Operating temperature Topr -40 +85 -40+85 -40+85 Storage temperature Tstg -55+150 -55+150 -55+150 Output current Iout 1300 1300 2500 mA Junction temperature Tjmax 150 150 150 *1 Reduced by 11.6 mW/ over 25, when mounted on a glass epoxy board (70 mm x 70 mm x 1.6 mm). *2 Reduced by 17.6 mW/ over 25, when mounted on a glass epoxy board (70 mm x 70 mm x 1.6 mm).
