SA56203 Datasheet One-chip Motor Driver

Manufacturer: NXP Semiconductors

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-mutated spindle motor uses PWM switching.

Key Features

  • s Low heat generation due to power-efficient direct full-bridge switching of spindle motor driver s Controlled spindle motor current during acceleration and brake s Reverse torque brake function (full bridge) s Adjustable spindle motor current limiter s Internal regeneration for EMF of spindle motor s Current-steering PWM controlled stepper motor driver for sled s Four class-AB linear channels for loading motor and 3D actuators (focus, tracking and tilt) s Tracking actuator driver with back EMF a.
