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 FAN8423D. When the
Short Brake function is active, all upper Power TRs turn off and all lower Power TRs turn on. This slows down the motor.
3. START/STOP (POWER SAVE)
When Start/Stop function is active, all Power TRs turn off.
