■ Overview

The AN8737SB is a BTL type 3-channel driver IC, adopting a current feedback system for 2 channels, which makes it optimum for an actuator and a motor driver of CD-ROM/DVD-ROM. It can also constitute an optimum system in combination with the AN8488SB, a spindle plus loading driver IC. A surface mount-type package of good heat radiation characteristic is used.

■ Features

• Little phase delay due to a current feedback system (2 channels for actuator)

• The remaining channel is available for either traverse or loading motor drive.

• Wide output dynamic range (4 V/IO = 800 mA)

• Standby function built in (all channels can be muted.)

• Thermal shut-down circuit built in

• With thermal flag pin

■ Applications

• CD/CD-ROM player

• DVD/DVD-ROM drive
