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.
