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.
