The AN8387S is an IC that incorporates 2 circuits of BTL drivers for driving various DC motors such as actuators (focus, tracking traverse), spindles, and loading of the CD players.
The Panasonic AN8387S is an integrated circuit featuring two circuits of voltage-driven BTL (Bridge-Tied Load) drivers. It is specifically designed for driving various DC motors found in CD/CD-ROM players, such as those used for focus, tracking traverse, spindles, and loading mechanisms.
The device operates with a supply voltage range of Vcc=3.5V to 9V and PVec=1.5V to 9V. It includes built-in features such as thermal protection (operating up to 160°C), power control pins, and driver output voltage limiting pins to ensure safe operation under various conditions.
