We live in an era where optimized product lines for faster time to market are gaining traction. Various support and simplification solutions targeting motor controllers have emerged, shortening development times.

Onsemi announced on the 28th the launch of its new ecoSpin family of brushless DC (BLDC) motor controllers.

The company announced that it supports a solution that simplifies the development of high-voltage motor control systems in applications such as HVAC, refrigeration, and robotics by combining control and driver functions in a system-in-package (SiP) solution.

The first product to be released in the EcoSpin family is the ECS640A, a 3-phase BLDC motor controller designed for reliable high-voltage operation up to 600V. The compact ECS640A features built-in, reliable gate drivers, an Arm® Cortex-M0+ microcontroller, three sense amplifiers, and three bootstrap diodes, enabling it to support sensored or sensorless motor control architectures.

“This highly integrated solution reduces time to market by eliminating the need for application-specific designs and simplifying solution reuse as BLDC motor power level requirements change,” said Michelle de Mai, vice president of ON Semiconductor’s Industrial Solutions business unit. “It replaces larger, more complex devices while reducing PCB routing area by approximately 20 percent compared to implementing discrete components, providing an overall compact solution with improved reliability.”

Integration into a single IC package (10 x 13 mm) redefines BLDC motor control performance by optimizing power stage layout and reducing noise. This allows for rapid reuse on alternative platforms by simply changing individual power components and updating the software. The reduced BOM simplifies sourcing challenges associated with multiple types of individual devices.

To optimize performance, the ECS640A supports conventional motor control techniques, including trapezoidal and vector control. Advanced commutation algorithms are available on the Cortex-M0 platform. ON Semi emphasizes that these technologies enable improved motor flux and torque control across a wide speed range, while also improving power efficiency by 3-5%.
