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