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

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

– Built-in current limiter and Hall bias circuits.
– Built-in FG output

-Built-in rotation direction detector.

-Built-in reverse rotation prevention circuit.
-Built-in short brake pin
