AT5660
Preliminary Product Information
5-Channel Motor Driver for DVD/VCD
Features
Description
˙2 channels of DC motor BTL driver
˙2 channels of BTL driver for coils with
current feedback
˙1 channels forward/reverse control DC motor
driver
˙Built-in suspension function.
˙Built-in thermal shutdown circuit.
˙Operating voltage: 4.5V~13.2V
The AT5660 is a 5-channel BTL driver IC. Two
of them can drive DC motors and two can drive
coils, such as the focus and tracking actuators of
a CD-ROM/DVD-ROM/DVD-Player system,
with current feedback. It also built-in one
channel bi-direction DC motor driver for Tray.
Applications
CD-ROM/DVD-ROM/CD-RW drives
DVD player.
