Qorvo introduces a new family of power application controllers

     Qorvo, a leading provider of core technologies and RF solutions for mobile, infrastructure and defense applications, today announced the PAC5xxx, the most powerful new power application controller (PAC) family on the market. This family of single-chip SOC controllers delivers high efficiency, high performance and long battery life for brushless direct current (BLDC) motor powered tools.

     Larry Blackledge, general manager of Qorvo's Programmable Power Management business unit, said: "Qorvo pioneered an integrated, controllable, programmable smart gate driver solution that integrates a high-performance FLASH MCU on a single chip. "With PAC5527, Oems are able to design highly reliable, high-performance tools with minimal footprint."

     Qorvo's new PAC5527 Power Application Controller  (PAC™) integrates several modules in a single-chip SOC, including the FLASH based, high-performance 150MHz Arm® Cortex-M4F® with 128kB of built-in FLASH; Power management module; Programmable current high and low end gate drivers; Signal conditioning module. This combination can significantly save PCB space and reduce BOM by up to 30% compared to competing solutions.

     With its high-performance MCUS, designers are able to add additional value-added features such as safety standards, diagnostics, and self-test capabilities to enhance overall system reliability. Consumers will also benefit from lighter, more compact, more reliable electronic devices with longer battery life.

     BLDC motors are widely used because of their maintenance-free, long service life, high power efficiency and low noise operation. In addition to electric and garden tools, the next generation of systems will shift from brushless DC motors to brushless DC motors, including white goods, HVAC systems, automotive, aerospace, defense and medical devices.
