3Phase spindle motor driver for CD-ROM
BD6669FV
BD6669FV is a 3-phase spindle motor driver adopting 180° PWM direct driving system. Noise occurred from the motor
driver when the disc is driven can be reduced. Low power consumption and low heat operation are achieved by using
DMOS FET and driving directly.
zApplications
CD-ROM
zFeatures
1) Direct-PWM-Linear driving system.
2) Built in power save circuit.
3) Built in current limit circuit.
4) Built in FG-output.
5) Built in hall bias circuit.
6) Built in reverse protection circuit.
7) Built in short brake circuit.
8) Low consumption by MOS-FET.
9) Built in capacitor for oscillator.
