B built-in thermal shutdown circuit. B operating voltage: 4.5v~13.2v description the at5660 is a 5-channel btl driver ic. two of them can drive dc mo tors 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. block diagram aimtron reserves the right without notice to change this circuitry and specifications.
