System Motor Driver ICs for CD/DVD Players
1ch Spindle
Motor Driver ICs
BA6859AFP-Y,BA6664FM,BD6671FM
No.10011EAT03
●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).
●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
