For Optical Disc

Low Noise PWM-based Single Chip Motor Driver IC AN4820FHQ

ꢀ Overview

Unit:mm

The AN4820FHQ is a single chip IC incorporating PWM system 3-channel

9.00 0.ꢀ0

7.00 0.ꢀ0

driver for optical pickup and mechanism driving based on a direct PWM or

ꢀ5

pulse width modulation driving system for a spindlemotor driving block.

It is an IC best suited for a notebook personal computer thanks to it slow power

consumption as well as its noise and vibration reduction.
