AN8787NSB

4-channel linear driver IC for CD/CD-ROM drive

s Overview

The AN8787NSB is a 4-channel driver IC that

has 2-channel of H-bridge method actuator driver

with current feedback, one channel of BTL type

traverse driver and one channel of tri-state output

type loading driver. It is optimum for actuator or

motor driver of CD/CD-ROM player. It comes with

a surface mount package that excels in heat radiat-

ing characteristic.

s Features

• Little phase delay due to current feedback method

(2-channel for actuator)

• Channels for loading motor (H-bridge system) are

available for three modes of forward rotation, re-

verse rotation and braking

• Muting SW with 2 modes: A loading channel is in

operation, and the other 3 channels are in muting;

Loading is in muting and the other 3 channels are

in operation.

• Standby switch to stop all functions

• Wide output dynamic range is available regard-

less of a reference power source on the system.

• I/O gain setting by an external resistor

• Thermal shut-down circuit built-in (with hyster-

esis)

s Applications

• CD/CD-ROM drive

• DVD/DVD-ROM drive
