The BA6858A and BA6859A series are ICs developed for CD-ROM spindle motor drives. In addition to the functions of the BA6849 series, (short brake, reverse-rotation prevention circuit, rotation direction dector, and FG output), the BA6858A and BA6859A series have a built-in brake mode switching pin. With torque command input, these series are compatible with the DSP3.3V. In addition, the BA6858A series has an FG composite output.

Features

1) Three-phase, 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.

8) Built-in brake mode switching pin.

9) DSP3.3V compatible.

Applications

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