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

●Absolute maximum ratings (Ta=25℃)
