Optical disc ICs
Ι
) Forward-rotation mode
In this mode, the disc rotation is started and accelerated.
When forward-rotation signal inputs from the Hall elements to the positive spindle-drive input terminals
(SPIN
>
VC), the spindle-drive output terminals output forward torque signal.

) Braking mode
In this mode, the disc rotation is decelerated and stopped.
Reverse-rotation braking
When the forward-rotation signal inputs from the Hall elements to the negative spindle-drive input terminals
(SPIN
