Overview

The AN41204A optical disc motor drive IC incorporates a

1-channel 3-phase full-wave PWM motor driver featuring

low vibration and noise as well as a 5-channel PWM output

driver for linear input. Integrating a spindle driver and

channel driver on a single chip and using small, thin

packaging reduces the mounting area. This helps to develop

equipment that is more compact, slim and lightweight.

Feature

· All-channel PWM driving power consumption is among the

lowest of its kind.

· Low-vibration and low-noise sinewave PWM is used to

drive the spindle section.

· Dead zone-less PWM driving for focus, tracking and tilt.

· Stepper motor drivers on two channels.

· Built-in thermal shutdown function.

· Compact, slim package.

Applications

Slim DVD recording units (RAM/+RW/-RW), optical disc units such as slim combination drives and car

navigation systems.

Achieving a 1-chip motor drive.
