Qorvo motor driver saves time, cost and space
Qorvo has added a highly-integrated brushless DC (BLDC) motor driver to its family of power management products, enabling smaller size, reduced design time and lower bill of material (BOM) compared to a discrete approach in automotive and industrial motor control. .
According to the company, the new SOI-based 160V, 3-phase gate driver ACT72350 replaces as many as 40 discrete components in a BLDC motor control system and offers a configurable AFE, enabling customers to configure their exact sensing and position detection requirements.
It also includes a configurable power manager with an internal DC-DC Buck converter and LDOs to support internal components and serve as an optional supply for the host MCU device. The wide 25V to 160V input range also allows customers to reuse the same design for a variety of battery-operated motor control applications including power and garden tools, drones, EVs and e-bikes.
Jeff Strang, Qorvo Power Management GM, said: "The newest addition to our power management portfolio brings added flexibility to our customers' BLDC designs, significantly reducing total solution size, design time and BOM cost. The ACT72350 provides the critical analog circuitry needed to implement a BLDC motor control system and can be paired with a variety of popular MCUs."
The ACT72350 delivers high efficiency through programable propagation delay, precise current sensing and BEMF feedback, and differentiated features for safety-critical applications.
This motor driver is available now in a 9x9mm, 57-pin QFN package. An evaluation kit is available here on qorvo.com and a model of the ACT72350 is available in Qorvo's QSPICE circuit simulation software.
Qorvo will show the ACT72350 and additional products at Embedded World 2025 (March 11-13, Nuremberg, Germany).
