CAMPBELL, Calif., Oct. 10, 2023 /PRNewswire/ -- Halo Microelectronics (SSE: 688173), a maker of analog and power management integrated circuits enabling energy-efficient smart systems, announces the launch of its AEC-Q100 Grade 1 qualified low-IQ synchronous boost controller with spread spectrum.

Key Points: 
  • CAMPBELL, Calif., Oct. 10, 2023 /PRNewswire/ -- Halo Microelectronics (SSE: 688173), a maker of analog and power management integrated circuits enabling energy-efficient smart systems, announces the launch of its AEC-Q100 Grade 1 qualified low-IQ synchronous boost controller with spread spectrum.
  • The HL8021 is a high-performance boost controller driving the N-channel MOSFET synchronous boost power stage, operating from a wide input supply range from 4.5V to 40V.
  • When the controller derives bias from the output voltage, it can operate from an input supply as low as 1V after startup.
  • This operation mode is controlled by the Spread Spectrum selection pin.

The alliance is an open, non-profit association that was initiated by various companies to standardize LPWAN technologies.

Key Points: 
  • The alliance is an open, non-profit association that was initiated by various companies to standardize LPWAN technologies.
  • The founding members of the LoRa Alliance include Actility (France), Cisco (US), IBM (US), Semtech (US), and other leading telecom operators.
  • LoRa is a chirp-based, spread-spectrum technology that uses a wider bandwidth and takes a broader spectrum compared to SigFox.
  • Thus, it is more suitable for applications that demand higher bandwidths.\nWi-Fi has remained one of the most dominant wireless connectivity technologies in consumer electronics and enterprise applications.
