ON Semiconductor Launches ecoSpin Series to Redefine Brushless DC Motor Control

ecoSpin™ BLDC motor control solution with embedded gate driver and microcontroller engine operates reliably up to 600 V with scalable power

October 28, 2022 - ON Semiconductor (NASDAQ: ON), a leader in smart power and smart sensing technologies, has launched the new ecoSpin™ series of brushless DC (hereinafter referred to as "BLDC") motor controllers. ON Semiconductor simplifies the development of high-voltage motor control systems for applications such as heating, ventilation and air conditioning (HVAC), refrigeration and robotics by integrating control and drive functions in a complete system-level package (SiP).

The first device in the ecoSpin family is the ECS640A, a three-phase BLDC motor controller that operates reliably at high voltages up to 600 V. The compact ECS640A includes reliable gate drivers, an Arm® Cortex-M0+ microcontroller, three sense amplifiers, three boost diodes, and supports sensored or sensorless motor control architectures.

“Using this highly integrated solution reduces time to market by eliminating design cycles in the application, simplifying solution reuse when the need arises to scale BLDC motor power levels,” said Michel De Mey, vice president of ON Semiconductor’s Industrial Solutions Division. “This solution replaces many larger, more complex components, improving reliability while reducing PCB routing area by approximately 20 percent compared to discrete solutions, making the overall solution compact.”

This solution, integrated in a single IC package (10×13 mm), optimizes the power stage layout and reduces noise, thus redefining the control performance of BLDC motors. The solution can be quickly reused on other platforms by simply replacing discrete power devices and updating software. The reduction of the bill of materials (BOM) simplifies the challenges caused by sourcing many different discrete components.

To optimize performance, the ECS640A supports traditional motor control techniques, including trapezoidal control and vector control. In addition, the internal Cortex M0 platform can also support more advanced direct flux and torque control algorithms, which can improve the control of motor flux and torque over a wider speed range, and improve power efficiency by 3% to 5% .

The ECS640A brings a new level of ease of use to BLDC motor control with a compact system design and user-friendly tools to speed up the design process. The ECS640A is available now. Please contact ON Semiconductor's sales support and authorized distributors to purchase.
