BD6667FM

00W096A Spindle motor driver IC for CD-ROM/RW BD6667FM Description 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. Features 1) Direct PWM drive 2) Built-in power save circuit 3) Built-in current limit circuit 4) Built-in FG 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 Applications CD-ROM/RW HSOP-M28 Dimension (Units : mm) 18.5±0.2 28 15 9.9±0.3 7.5±0.2 1 5.15±0. 1 14 2.2±0. 1 0. 1 1 0.8 0.35±0. 1 0.3Min. 0. 15 0.25±0. 1 Absolute Maximum Ratings (Ta=25˚C) Parameter Applied voltage (For 5V power supply) Applied voltage (For motor power supply) Power dissipation Operating temperature range Storage temperature range Output current ∗1 Mounted on a glass epoxy board (70mm×70mm×1.6mm) ∗1 Derating:17.6mW/˚C for operation above Ta=25˚C. ∗2 Do not exceed Pd, ASO and Tj=150˚C.
