Tired of noisy or bulky motor control? This compact motor driver helps pumps, fans, and actuators work smoothly and easily.
Engineers designing compact industrial systems such as pumps, fans, or robotic actuators often face a common problem: motor control that is efficient, quiet, and easy to implement within tight space and time limits. Traditional motor drivers can be bulky or complex, slowing product development and increasing design effort.
The MLX81339 from Melexis tackles these challenges by combining an embedded motor driver, controller, and communication interface in one IC. It supports 3-phase BLDC and bipolar stepper motors up to 40 W, bringing reliable motion control to space-constrained applications. Its Flash programmable memory allows engineers to fine-tune performance for specific needs, cutting the need for external components and reducing system cost.
Typical applications include positioning motors, thermal valves, ventilation systems, and pumps in industrial or home equipment. An automotive-qualified variant also supports fans and blowers used in vehicles, extending its use to mobility systems where space and reliability are equally critical.
By using field-oriented control (FOC), the device enables smooth and quiet motor operation, improving efficiency and reliability across the speed range. It can drive motors at 20 W or 40 W and includes built-in protection against overcurrent, overvoltage, undervoltage, and overtemperature conditions.
To simplify setup, Melexis offers the StartToRun web tool, which automatically generates configuration files based on user-entered motor and system parameters, removing the need for deep control algorithm expertise and accelerating time to market.“With the MLX81339, we’re enabling smarter motor control in applications that demand space-efficiency, ease of use, and robust performance,” said Marc Lambrechts, Product Line Director at Melexis. “These devices deliver the performance demanded by modern applications, while removing development overhead and costs. By enabling sensorless FOC control in a compact format, with a highly configurable version available and a plug-and-play code-free variant to come, we’re helping engineers bring smart motor applications to life faster and more efficiently.”
