PMIC - Motor Drivers, Controllers are specialized Integrated Circuits (ICs) designed to manage and regulate the operation of motors in electronic devices. Their primary function is to control the speed, direction, torque, and overall motion of motors with precision and efficiency. These components serve as the intermediary between the microcontroller and the motor, interpreting electronic commands into physical motion by adjusting electrical output. With capabilities such as built-in protection against overcurrent and thermal overload, they ensure the motors operate safely and extend the lifespan of the overall device.
Motor drivers and controllers are commonly found in a vast array of applications, including but not limited to, consumer electronics, automotive systems, industrial machinery, and robotics. These PMICs feature characteristics such as variable speed and direction control, low power consumption, and high integration, which are essential for fine-tuned motor management and space-saving designs. Some well-known manufacturers in the market that produce these sophisticated PMICs include Texas Instruments, STMicroelectronics, Allegro Microsystems, Infineon Technologies, and ON Semiconductor.
