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 three-
phase 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.
