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
Brushless DC (BLDC) Controllers	Commutation logic, Hall sensor interface	Electric vehicles, drones
Integrated FET Drivers	Embedded MOSFETs, thermal shutdown	Portable devices, power tools

3. Structure & Components

A typical PMIC for motor control consists of:

Physical Structure: Standard packages like QFN, TSSOP, or BGA for compact integration
Internal Modules:
- Gate drivers for MOSFET/IGBT control
- Current sensing amplifiers
- Protection circuits (OCP, OTP, UVLO)
- Power supply regulation units
Interfaces: PWM, SPI, I2C, or analog inputs for control signals

4. Key Technical Specifications

Parameter	Description & Importance
