Qorvo® Unveils Groundbreaking Integration and Performance with Motor Control and Drive SoC for Brushless DC Power Tools

New Power Application Controller (PAC™) Reduces BOM by as much as 30%

GREENSBORO, NC – November 14, 2019 – Qorvo® (Nasdaq:QRVO), a leading provider of innovative RF solutions that connect the world, today introduced the highest-performing MCU and integrated motor control and drive product on the market. The single, system-on-chip (SoC) controller enables high efficiency, high performance and a longer battery life in tools powered by brushless DC (BLDC) motors.

David Briggs, director, Qorvo Power Management & Motor Drive Products, said, “Qorvo is the first to deliver an integrated, programmable and intelligent gate driver solution with a high-performance FLASH MCU in a single device. The PAC5527 allows OEMs to design high-performing, highly reliable tools in the smallest footprint.”

Qorvo’s new PAC5527 Power Application Controller® (PAC™) integrates multiple devices into a single SOC – a high-performance, FLASH-based 150MHz Arm® Cortex-M4F® with 128kB of FLASH; power management; programmable-current high-side and low-side gate drivers; and signal conditioning components. This combination enables significant PCB space savings and reduces the BOM by as much as 30 percent over competing solutions.

Its high-performance MCU allows designers to add other value-added features, such as safety standards, diagnostics and self-checking capabilities, enhancing tool reliability and quality. Consumers benefit from lighter, more compact and reliable tools with longer battery life.

BLDC motors are seeing widespread adoption, thanks to their maintenance-free operation, longer life span, power efficiency and quieter operation. In addition to power and garden tools, next-generation systems that are switching from brushed DC motors to BLDCs include white goods, HVAC systems, automobiles, aerospace, defense and medical devices.
