Motor driver ICs  
3Phase spindle motor driver for CD-RW  
BD6670FM  
BD6670FM is a 3-phase spindle motor driver adopting 180° PWM direct driving system. Noise occurred from the motor  
driver when the disc is driver can be reduced. Low power consumption and low heat operation are achieved by using  
DMOS FET in output and driving directly.  
!Applications  
CD-RW  
!Features  
1) 180 degree Direct-PWM driving system.  
2) Built in power save circuit.  
3) Built in current limit circuit.  
4) Built in FG-output.  
5) Built in 3phase synthesized FG-output.  
6) Built in hall bias circuit.  
7) Built in reverse protection circuit.  
8) Built in short brake circuit.  
9) Low consumption by MOS-FET.  
10) Built in capacitor for oscillator.  
11) Built in gain switch and current limit switch.
