2. SHORT BRAKE
When the pick-up mechanism moves from the inner to the outer spindle of the CD, the brake function of the reverse voltage is
commonly employed to decrease the rotating velocity of the spindle Motor.
However, if the spindle motor rotates rapidly, the brake function of the reverse voltage may produce more heat at the Drive IC.
To remove this shortcoming and to enhance the braking efficiency, the short brake function is added to FAN8420D. When the
short brake function is active, all upper power TRs turn off and all lower power TRs turn on, and the motor slows down. But
FG and DIR functions continue to operate normally.
3. POWER SAVE
When power save function is active, all power TRs turn off.
