Technical Specifications

The AN6652L operates on a supply voltage typically ranging from 4.5V to 5.5V. It features a built-in servo amplifier with adjustable gain and phase compensation to optimize motor control performance. The motor driver output stage provides sufficient current to drive small servo motors. The IC includes a brake circuit to quickly stop the motor when necessary. The speed control function allows for precise adjustment of the motor's rotational speed. The FG amplifier processes the feedback signal from the motor's frequency generator, providing accurate speed information. The device is commonly available in a small outline package (SOP) or similar surface mount package. The power dissipation is generally low, contributing to energy-efficient operation. UTC ensures the reliability and performance of the AN6652L through rigorous testing and quality control processes.
