3-phase motor driver for

CD-ROMs

BA6848FP / BA6853FS

The BA6848FP and BA6853FS are single-chip ICs developed for CD-ROM spindle motor drives. These ICs are 3-

phase, full-wave, pseudo-linear drives with FG output, FG composite output, and reverse-rotation pins built-in for high

functionality and high performance.

FApplications

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

FFeatures

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

2) Built-in PS pin for power save mode when ON.

3) Built-in thermal shutdown and current limiter circuits.

4) Built-in Hall bias circuit (for the BA6848FP).

5) Built-in FG output and FG composite output.

6) Built-in reverse-rotation pin.
