Motor driver ICs Rev.A 1/16 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. 10) Built in rotation detect.
