SA56202  
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-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.  
2. Features  
True-Silent PWM spindle motor driver  
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)  
Low on-resistance D-MOSFET output power stages  
Built-in thermal shutdown, thermal warning and temperature diode  
Interfaces to 3 V and 5 V logic  
Package with low thermal resistance to heatsink (reflowable die pad).  
3. Applications  
DVD+RW, DVD-RW, DVD-ROM and DVD-RAM  
Combi  
CD-ROM and CD-RW  
Other compact disk media.
