Motor driver ICs

3-phase motor driver for

CD-ROMs

BA6849FP / BA6849FP-Y / BA6849FM /

BA6849FS

The BA6849 series are ICs developed for CD-ROM spindle motor drives. These ICs possess a short brake and reverse-

rotation brake for two types of brake functions, and also contain FG output and rotation direction detection (FR) circuits,

making them high-functionality and high-performance ICs.

FApplications

CD-ROM, CD-R, CD-RW, DVD-ROM, and DVD-RAM

FFeatures

1) Three-phase, full-wave, pseudo-linear drive system.

2) Built-in power save and thermal shutdown functions.

3) Built-in current limiter and Hall bias circuits.

4) Built-in FG output.

FAbsolute

maximum ratings (Ta = 25_C)

5) Built-in rotation direction detector.

6) Built-in reverse rotation prevention circuit.

7) Built-in short brake pin.
