Overview
SA56203 One-chip motor driver Rev.
01 — 30 September 2004 Preliminary data sheet 1.
General description The SA56203 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 PWM switching.
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 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 SA56203 is available in an exposed die pad HTSSOP56 package.
