The BA6665FM is a CD‑ROM/DVD‑ROM spindle motor driver with reverse‑rotation prevention, power‑save, thermal‑shutdown, FG output and Hall bias circuits.
The BA6665FM optical disc motor driver is designed for CD‑ROM, CD‑RW and DVD‑ROM applications. It uses a 3‑phase full‑wave pseudo‑linear driving system to provide high performance and multifunction operation.
Key features include built‑in power‑save, thermal‑shutdown, current‑limit, Hall‑bias and FG‑output circuits, as well as a switching function for regular and reverse rotations. The datasheet provides absolute maximum ratings, recommended operating conditions, pin assignments, electrical characteristics, measurement circuits and package dimensions.
