AT5669
5-Channel Motor Driver for DVD/VCD
with 2 Linear Regulator and 1 OPAMP
Features
4 channels of DC motor BTL driver
1 channels forward/reverse control DC motor
driver
Built-in suspension function.
Built-in 2 Linear Regulator
Built-in 1-Channel operational amplifier.
Built-in thermal shutdown circuit.
Operating voltage: 4.5V~13.2V
Description
The AT5669 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 It
also built-in one channel bi-direction DC motor
driver for Tray. Using the built-in linear
regulator, it can be save the PCB space. It also
includes 1 operational amplifier.
Applications
CD-ROM/DVD-ROM/CD-RW drives
DVD player.
