Motor Driver ICs: Introduction
- A motor driver IC is an integrated circuit chip, which is used to control motors in autonomous robots. A motor driver IC acts as an interface between the motor and microprocessors in the robot.
- A majority of microprocessors require low voltage and a small amount of current to operate, whereas motors require relatively high voltage and current to operate. Hence, motor driver ICs are primarily used in autonomous robotics, as current cannot be supplied to the motor from the microprocessor.
- Additionally, motor driver ICs help perform various operations, such as selecting the reverse or forward rotation of the motor, protecting against overload, and regulating the motor speed
- Motor driver ICs are available with three types of motors i.e. brushed DC motor, brushless DC motor, and stepper motor
- Motor driver ICs are used in multiple applications such as printers, scanners, sunroofs, wipers, HVAC blowers, and radiator fans. These ICs are employed in several end-use sectors such as automotive, industrial, medical, and consumer electronics.

Rise in Demand for Motor Driver ICs for Use in Industrial Automation
- Motor driver ICs are largely used in industrial automation processes, such as tool machines and robots, logistics systems, food, and packaging. This is considered a major factor driving the global motor driver ICs market.
- In industrial automation, in order to speed up the assembly line process, manufacturers are using industrial robots that are operated and controlled by using motor drivers. These robots perform operations at a high speed and with high accuracy and they consume less power. This makes the operation more efficient.
- As a result of these advantages, the demand for motor driver ICs for use in industrial automation applications is increasing. This is expected to drive the global motor driver ICs market during the forecast period.
Automotive Segment to Witness Lucrative Opportunities
- The automotive industry has emerged as an attractive sector for investments for organizations across the globe. In the automotive industry, motor driver ICs are increasingly used in automobiles for HVAC blowers, radiator fans, sunroofs, wipers, and oil pumps.
- Manufacturers mostly provide motor driver ICs with brushless DC motors instead of those with brushed DC motors, as they have higher efficiency and longer lifespan. Also, they lack brush-generated electrical noise.
- Moreover, use of motor driver ICs offers protection against faults in power supply, due to which these devices are significantly used in automobiles
- Thus, rise in the use of motor driver ICs in automobiles is expected to offer lucrative opportunities to the global motor driver ICs market during the forecast period
