LONG BEACH, Calif. USA, (February 26, 2024) —Amber Semiconductor, Inc. announced a  reference design for brushless motor applications using AmberSemi’s breakthrough AC to DC  conversion semiconductor system to power ST’s STM32 microcontrollers. This reference design  will be demonstrated at the Applied Power Electronics Conference in Long Beach, CA (Feb 25- 29, 2024). amber semi apec The reference design takes a direct AC input through AmberSemi’s patented AC Direct DC  Enabler™ technology and powers the ST microcontroller, gate drivers and Hall sensors for  brushless motor applications. Compared to typical brushless DC motor-control design,  AmberSemi’s off-line solution provides up to 5 watts of regulated output, enough to drive  today’s requirement of control logic and sensors, with additional headroom for expanded  intelligent functionality. The Enabler offers selectable output voltages determined by internal,  configurable register settings or with a simple external voltage-divider feedback circuit. An  adjustable current limiting feature on the VDC output offers protection and notification via an  interrupt signal. Generation of the DC output is controlled by an internal register selection of  regulator switching frequencies. This allows the designer to easily optimize between efficiency,  reduced ripple, interference with sensitive system circuitry, and board space footprint.  In addition to meeting the tasks of a high-performance AC-DC offline converter, the Enabler  also provides integrated functionality for supporting the next generation of intelligent  applications in IoT/IIoT/AIoT. Through the integrated SPI communication port and coupled with  an SPI-equipped MCU, such as one from the STM32 family of microcontrollers, the designer can  set alarm bits, protection thresholds, monitor status bits for over-current, over/under voltage,  over-temperature and interrupt signals on the Enabler. Achieving real-time reporting and  telemetry monitoring of the motor load are key building blocks towards a preventative  maintenance plan required in industrial applications.  “The reference design for brushless motors shown at the APEC 2024 conference is set to  demonstrate the advantages the Amber and ST technologies are capable of delivering to the  AC-powered application landscape, simplifying the power-supply circuitry, reducing the overall  BOM and PCB footprint, and improving efficiency,“ said Sean Newton, Applications Director, Microcontrollers, Microprocessors, and Wireless Products at STMicroelectronics.  “We are excited to showcase with ST, a global, market-leading semiconductor company, a  reference design around our breakthrough technologies at APEC 2024,” said Thar Casey, CEO at  AmberSemi. “The timing of this reference design, as we enter the commercialization phase for  our first semiconductor products, could not be more ideal. It is timed with the expansion of our  design-in evaluations of our semiconductor engineering samples in 2024 with our electrical  product manufacturing partners.”  AmberSemi discovered a way the physics of electricity is managed differently – digitally – in  silicon chips. The company’s mission is to transform electrical product power management  architecture globally from outdated, 1950’s-era electro-mechanical power technologies,  standard today in every electrical product, to smaller, safer, and smarter silicon chips.   Mr. Casey continued, “our products enable a change in the design possibilities for electrical  products by delivering smarter, smaller more dynamic power systems to electrical products not  only enabling the possibilities of more streamlined product designs and form factors, but also  opening the possibilities to pose a significantly broader set of features within these products.”  About AmberSemi   Amber Semiconductor, Inc is a leading developer of patented, innovative solid-state power  management technologies for the digital control of electricity.
