Qorvo's PAC52410 further expands the company’s portfolio of power application controller (PAC) products with an application-optimized solution for controlling and powering next-generation appliances, devices, and equipment. Typical apps include:

Industrial BLDC motor control (pumps, fans, robotics)
Power and garden tools
Small appliances
E-mobility

In addition to the series’ efficiency and ease of use, it brings new features such as V_DS sensing, cycle by cycle (CBC), enhanced sample and hold (S&H), windowed watchdog timer, and more.

The PAC52410 integrates a 50-MHz Arm Cortex-M0 32-bit microcontroller core with Qorvo's proprietary Multi-Mode Power Manager, Configurable Analog Front End, and Application Specific Power Drivers to form the most compact microcontroller-based power and general-purpose application systems.

These include:

44-V buck/SEPIC dc-dc controller with external NCH FET
5-V/200-mA system supply
Three high-side 44-V, 1.2-A (source)/1.8-A (sink) gate drivers
Three low-side 20-V, 1.2-A (source)/1.8-A (sink) gate drivers
Programmable overcurrent shutdown
Programmable comparator hysteresis and blanking
V_DS sensing
Simultaneous sample and hold for three-phase

The PAC52410/11 is available in a 48-pin, 6- × 6-mm TQFN package. To request a sample, go here.

Lee Goldberg is a self-identified “Recovering Engineer,” Maker/Hacker, Green-Tech Maven, Aviator, Gadfly, and Geek Dad. He spent the first 18 years of his career helping design microprocessors, embedded systems, renewable energy applications, and the occasional interplanetary spacecraft. After trading his ‘scope and soldering iron for a keyboard and a second career as a tech journalist, he’s spent the next two decades at several print and online engineering publications.

Lee’s current focus is power electronics, especially the technologies involved with energy efficiency, energy management, and renewable energy. This dovetails with his coverage of sustainable technologies and various environmental and social issues within the engineering community that he began in 1996. Lee also covers 3D printers, open-source hardware, and other Maker/Hacker technologies.

Lee holds a BSEE in Electrical Engineering from Thomas Edison College, and participated in a colloquium on technology, society, and the environment at Goddard College’s Institute for Social Ecology. His book, “Green Electronics/Green Bottom Line - A Commonsense Guide To Environmentally Responsible Engineering and Management,” was published by Newnes Press.

Lee, his wife Catherine, and his daughter Anwyn currently reside in the outskirts of Princeton N.J., where they masquerade as a typical suburban family.
