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. Block Diagram Aimtron reserves the right without notice to change this circuitry and specifications.
