General description The SA56203S is a one-chip motor driver IC that is capable of driving all motors of CD or DVD systems e.
g.
spindle, sled and loading motors and actuators on the optical pick-up unit.
The driver intended for the 3-phase, brushless, Hall-commutated spindle motor uses True-Silent PWM.
This proprietary technology ensures that all 3-phase motor currents are sinusoidal resulting in an optimally silent driver.
Internal regeneration of the back EMF of the spindle motor enables the driver to operate in current-steering mode without using external power-dissipating sense resist...
