Spindle motor driver IC for CD-ROM/RW
BD6667FM
Description
Dimension (Units : mm)
The BD6667FM has achieved in high-efficiency and
low power consumption due to the adoption of
MOSFET output and direct PWM drive.
Power save circuit, current limit circuit, FG 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.
