3-phase motor driver for CD-ROMs
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.
Features
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.
5 Built-in rotation direction detector.
6 Built-in reverse rotation prevention circuit.
7 Built-in short brake pin.
Applications
CD-ROM, CD-R, CD-RW, DVD-ROM, and DVD-RAM
