■ 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.

■ 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, reverse 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)

■ Applications

• CD/CD-ROM drive

• DVD/DVD-ROM drive
