Motor driver ICs

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
