ICs for CD/CD-ROM Player

AN8387S

2-channel Linear Driver

■ Overview

Unit : mm

The AN8387S is an IC which incorporates 2 circuits of

BTL drivers for driving various DC motors such as actua-

tors (focus, tracking traverse), spindles, and loading of

the CD players.

■ Features

Operating supply voltage range ; V_CC=3.5V to 9V

PV_CC=1.5V to 9V

•

Built-in 2 circuits of voltage driven BTL drivers

(maximun drive current : 500mA)

Quiescent current (current consumption at no input) ;

3.2mA

•

Provided with power control pin

5.5±0.3

7.6±0.3

(0.4)

Provided with driver output voltage limiting pin

Built-in thermal protective circuit

(operating temperature : 160°C typ.)

20-Lead SOP Package (SOP020-P-0300A)

■ Applications

Linear driving of the DC motors and actuators of the

CD players. CD radio cassette tape recorders, and so

on.
