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.

The PAC5527 is available now and offers these specifications:

  • 150MHz Arm® Cortex®-M4F
  • 128kB FLASH, 32kB SRAM with ECC
  • 12b 2.5MSPS SAR ADC with trigger and sequence engine
  • 16 3.3V IO
  • 10 5V Open-drain IO
Power Management
  • 48V Charge Pump DC/DC Controller
  • 5V/100mA system supply
  • LDOs for MCU Core, IO, Analog
  • Low-power hibernate mode (8µA)
Gate Drivers
  • 3 High-side and 3 low-side 48V gate drivers with programmable current
  • Integrated gate drive slew rate control
  • 6x6mm, 48-pin QFN
  • TA = -40°C to 125°C
