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

■ Overview

The AN8783SB employs one channel of power

op-amp. system and three channels of H-bridge

system. Two channels out of three channels of H-

bridge method are a current feedback system. So

this IC is optimum for driving an actuator and a

motor of CD/CD-ROM drive. It comes with a

surface mount package which excels in a heat ra-

diation characteristic.

■ Features

• Little phase delay due to current feedback system

(2-channel for actuator)

• 4 modes of forward, reverse rotations, braking and

standby can be selected from channels for load-

ing motor (H-bridge method) by a digital signal

from a microcomputer.

• Wide output dynamic range regardless of refer-

ence voltage of the system

• Setting the input level of a driver by an external

resistor is possible.

• PC (power cut) function built-in (common for ch.

1, ch. 3 and ch. 4)

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

esis)

■ Applications

• CD/CD-ROM drive
