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-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 resistors. The driver intended for the 2-phase sled
stepper motor operates in current-steering PWM mode. In addition the IC contains four
full-bridge linear channels that can be used to drive a loading motor and 3D actuators
(focus, tracking and tilt).
The SA56202 is available in an exposed die pad HTSSOP56 package.
