Panasonic AN8780SB Datasheet

ICs for CD/CD-ROM Player

■ Overview

The AN8780SB employs 4ch. H-bridge system that is
suitable for driver or actuator of CD player. Also it
employs the surface mounting type package superior in
radiation characteristics.

■ Features

•

Wide output D-range is available regardless of refer-

ence voltage on the system

•

4 ch. BTL Driver built-in. Particularly suitable for driver

of actuator or motor of 5 to 20Ω load.

•

2 ch. independently controllable PC (Power Cut) fea­ture, and 4 ch. simultaneously controllable PC feature
built-in.

•

Thermal shut down circuit (with hysteresis) built-in.

•

Control for proper heat of IC by separating the power
supplies for signal line and output line.

•

Provided with reset output pin.

•

Shot brake mode.

■ Application

CD player, CD-ROM, for drive of motor
