SA56202 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.

SA56202 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).

SA56202 Typical Application

· DVD+RW, DVD-RW, DVD-ROM and DVD-RAM
· Combi
·CD-ROM and CD-RW
·Other compact disk media.
