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.
Features
1) Direct PWM drive
2) Built-in power save circuit
3) Built-in current limit circuit
4) Built-in FG three-phase synthesis output
5) Built-in hall bias
6) Built-in reverse protection circuit
7) Low power consumption due to MOSFET output
8) Built-in short brake SW
9) Built-in rotation direction detection terminal
