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.
