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.
