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.
