One-chip motor driver Rev. 01 - 19 July 2004 Preliminary data sheet 1. General description The SA56202 is a one-chip motor driver IC that is capable to drive all motors of CD or DVD systems: spindle, sled and loading motors and actuators on the optical pick-up unit. The driver intended for the 3-phase, brushless, Hall-mutated 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 resistors. The driver intended for...
