1. Overview

Power Management ICs (PMICs) dedicated to motor drivers and controllers are specialized semiconductor devices that manage the operation of electric motors by regulating power delivery, speed, direction, and protection features. These components are critical in modern electronics for optimizing energy efficiency, ensuring precise motion control, and enhancing system reliability. They are widely used in robotics, automotive systems, industrial automation, and consumer electronics.
