BD6665FM

00W095A Spindle motor driver IC for CD-ROM/RW BD6665FM Description The BD6665FM has achieved high-efficiency and low power consumption due to the adoption of MOSFET output and direct PWM drive. Power save circuit, current limit circuit, FG threephase synthesis output, hall bias, reverse protection circuit, short brake SW, and rotation direction detection terminal are incorporated. The result is a multi-function and high-performance IC.
