Motor Drivers and Controllers

Motor Driver and Controller ICs are specialized mixed-signal semiconductor components designed to act as the power and control interface between digital processors and physical electric motors (including brushed DC, brushless DC - BLDC, stepper motors, and AC induction motors). These integrated devices combine control logic, gate drivers, current sensing, and robust power MOSFETs or H-bridges onto a single die, translating digital motion profiles into physical torque and rotation.

These drivers are vital in robotics, factory automation, automotive actuators, hard disk drives, and cooling fans. Selecting a motor driver requires matching the motor type to the driver architecture. Key parameters include operating voltage range, continuous and peak output current (A), commutation logic (such as microstepping for steppers, sensorless FOC for BLDC), integrated protection (overcurrent, overtemperature, stall detection), and digital interface (SPI, step/direction, or analog).
