The AM5669 is a five-channel BTL driver IC, in which four channels are voltage type BTL drivers for tracking and focus actuators, sled and spindle motors, the other one channel is DC motor driver for tray which supports forward/reverse control. This IC also contains two independent precise voltage regulators with adjustable range from 1.5V to 4V and a free comparator for spindle channel motor direction detection. The AM5669 is available in standard HSOP-28 package.
The AM5669 is a five‑channel BTL driver IC designed for DVD‑player actuators, offering four voltage‑type BTL drivers for tracking, focus, sled and spindle motors, plus a forward/reverse DC driver for the tray. It includes two adjustable voltage regulators (1.5 V‑4 V), a comparator for spindle direction detection, built‑in mute, level‑shift, and thermal‑shutdown circuits, and operates from 4.3 V to 8 V.
The device is supplied in an HSOP‑28 package and specifies absolute maximum ratings such as a 8.8 V supply voltage and 150 °C junction temperature. Electrical characteristics include a quiescent current of 16 mA, mute control voltages, and detailed output specifications for each driver channel. Mechanical dimensions, pin configurations, and a test circuit are also provided.
