OQ8844 - Digital Servo Driver DSD-2

Datasheet Summary

Description

The OQ8844 or Digital Servo Driver 2 (DSD2) consists of 1-bit class-D power drivers, which are specially designed for digital servo applications.

Three such amplifiers are integrated in one chip, to drive the focus and radial actuators and the sledge motor of a compact disc optical system.

Features

  • Servo functions.
  • 1-bit class-D focus actuator driver (3.3 Ω).
  • 1-bit class-D radial actuator driver (3.7 Ω).
  • 1-bit class-D sledge motor driver (2.5 Ω). Other features.
  • Supply voltage 5 V only.
  • Small package (SOT163-1).
  • Higher efficiency, compared with conventional drivers, due to the class-D principle.
  • Built-in digital notch filters for higher efficiency.
  • Enable input for focus and radial driver.
  • Enable input for sle.
