PMIC - Motor Drivers, Controllers

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.

2. Main Types & Functional Classification

Type	Functional Features	Applications
H-Bridge Drivers	Bi-directional current flow control, PWM integration	DC motor direction control in robotics
Stepper Motor Controllers	Microstepping, current regulation, position control	3D printers, CNC machines
