SA56203  
One-chip motor driver  
Rev. 02 — 10 December 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.  
2. Features  
Low heat generation due to power-efficient direct full-bridge switching of spindle motor  
driver  
Controlled spindle motor current during acceleration and brake  
Reverse torque brake function (full bridge)  
Adjustable spindle motor current limiter  
Internal regeneration for EMF of spindle motor  
Current-steering PWM controlled stepper motor driver for sled  
Four class-AB linear channels for loading motor and 3D actuators (focus, tracking and  
tilt)  
Tracking actuator driver with back EMF amplifier  
Loading motor driver with transresistance amplifier for loading current  
Low on-resistance D-MOSFET output power stages  
Built-in thermal shutdown and thermal warning  
Interfaces to 3 V and 5 V logic  
Package with low thermal resistance to heatsink (reflowable die pad)  
Lead free package.  
3. Applications  
DVD+RW, DVD-RW and DVD-RAM  
Combi  
CD-RW  
Other compact disc media.
