Additional preview pages of the SA56203S datasheet.

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.

s True-Silent PWM spindle motor driver s Low heat generation due to power-efﬁcient direct full-bridge switching of spindle motor driver s Controlled spindle motor current during acceleration and brake s Reverse torque brake function (full bridge) s Adjustable spindle motor current limiter s Internal regeneration for EMF of spindle motor s Current-steering PWM controlled stepper motor driver for sled s Four class-AB linear channels for loading motor and 3D actuators (focus, tracking and tilt) s T.
