ST’ hybrid controller simplifies full-feature implementation of USB-C sink premium applications

STMicroelectronics’ STUSB4531 USB Power Delivery (PD) sink controller introduces a new, patented hybrid mode that simplifies implementing optional USB PD features for added value in USB-powered and USB-chargeable devices.

The STUSB4531 contains a certified, hardwired USB PD stack that works with ST-proprietary AUTORUN algorithms to enable software-free power negotiation, supervision, and management. These AUTORUN algorithms simplify developing battery-charging and VBUS-powered electronics in equipment such as portable audio devices, wearables, set-top boxes, Wi-Fi access points, healthcare devices, and lighting. The latest updated algorithms can negotiate with AC adapters to ensure the optimum power profile, including adjustable voltage supply (AVS) and high-power charging in dead-battery mode for faster device reactivation.

The new hybrid mode now added to the STUSB4531 lets an external application processor interact with the stack to leverage the protocol layers for USB PD communication. This gives engineers extra flexibility to implement functions such as battery messaging, data role swapping, Alternate modes, and vendor-defined messages (VDM) while also easing software development and accelerating time to market.

Typical applications for charging with USB data include hard disk drives, point-of-sale (POS) terminals, printers, drones, and portable industrial devices. While VR headsets, infotainment devices, portable displays, and gaming consoles often combine USB power with Alternate modes for DisplayPort or Thunderbolt protocols, VDM enhances consumer accessories and medical devices.

By combining hardwired speed and simplicity with software-enabled flexibility, the STUSB4531 facilitates adoption of USB-C for charging and powering devices, mandated by ecodesign norms worldwide conceived to reduce electronic waste. The IC is certified according to the latest USB-C® 2.4 and USB PD 3.2 standards, as well as IEC 62680 confirming EU-conformity.

An extensive ecosystem supports developers using the STUSB4531, including an evaluation board (EVAL-SCS007V1), certified minimalistic reference design (EVAL-SCS006V1), graphical user interface (STSW-STUSB020), and NVM flasher (STSW-STUSB021). An open-source software library (STSW-STUSB022) will be available soon.

Arrow supports .lumen in scaling production of Its glasses for the blind

Arrow Electronics is collaborating with Romanian startup .lumen to scale intelligent guide glasses designed to replicate the key functions of a guide dog.

.lumen’s Glasses for the Blind replicate the essential functions of a guide dog by combining artificial intelligence (AI), six integrated cameras, and real-time haptic feedback on a single wearable headset. The glasses continuously scan and understand the environment in real time, detecting obstacles, identifying safe paths, and guiding the user with gentle directional vibrations.

The entire navigation system runs locally on the device, making it fully independent from the cloud. This architecture delivers ultra-low latency, which is essential for safe, reliable navigation in fast-changing environments such as crowded streets or unfamiliar indoor spaces.

.lumen exhibited on Jan. 5-9, 2026, at CES, Las Vegas, where they were named a CES Innovation Awards 2026 Honouree in the Accessibility and Longevity category, and also won the CTA Foundation’s 2026 Pitch Competition.

Arrow is providing engineering and supply chain services to enable .lumen to scale its production efficiently. This includes identifying, sourcing, and integrating the lengthy list of electronic components required, such as processors, cameras, sensors, and connectors. Arrow is also supporting .lumen with inventory reliability, cost control, and improved performance of the complex wearable technology.

By supporting the development of this technology, Arrow is expanding on its existing work in Semi-Autonomous Mobility (SAM), which uses intelligent technology to provide greater independence to people with physical disabilities. An example of Arrow’s previous work in this area is the Arrow SAM Car, the series of advanced cars that can be controlled by a quadriplegic race driver with support from an AI model and electronics developed by Arrow engineers.

“We are helping to create a device which will eventually make life better for millions of people,” said Vitali Damasevich, Arrow’s regional director of engineering in Eastern Europe. “At Arrow, we are committed to supporting the .lumen team to help ensure this breakthrough technology can be reliably and efficiently manufactured so it can get into the hands of those who need it most.”

“Growing up in a family where everyone but me had a disability, I realised how much technology can help people with disabilities, but also how rarely it’s built for people with disabilities. I founded .lumen to solve this,” said Cornel Amariei, founder & CEO of .lumen.

“The Glasses for the Blind use .lumen’s proprietary Pedestrian Autonomous Driving AI technology. It does everything a self-driving car does, but on the pedestrian side. The best part is this technology doesn’t need any infrastructure change.”

.lumen is currently taking orders for the device, which aims to provide users with unprecedented mobility and freedom. Future software updates include features such as “Take Me,” which is designed to integrate with mapping services and extend navigation capabilities beyond obstacle avoidance.

Infineon introduces the industry’s first Wi-Fi 7 IoT 20 MHz tri-radio device optimised for IoT

To support continued growth of connected devices in home, industrial and commercial markets, Infineon has introduced the AIROC ACW741x, a new product family that integrates a tri-radio with Wi-Fi 7, Bluetooth LE 6.0 with Channel Sounding, and IEEE 802.15.4 Thread, with Matter ecosystem support in a single device. This product family introduces the industry’s first 20 MHz Wi-Fi 7 device for IoT, provides Wi-Fi 7 Multi-Link for IoT for enhanced robustness in congested environments and has the industry’s lowest Wi-Fi connected standby power.

With the IoT connectivity market projected to reach 30 billion devices by 2030 [1], IoT device manufacturers continue to demand reliable, energy-efficient and cost-effective solutions. The Wi-Fi Alliance is introducing the 20 MHz device category for Wi-Fi 7 aimed at addressing the needs of the broader IoT ecosystem, and the AIROC ACW741x is the industry’s first product to support 20 MHz-only channels, with optimised radio performance and ultra-low power consumption.

As Wi‑Fi–connected IoT devices proliferate across homes and commercial environments, spectrum congestion and interference increasingly undermine wireless connectivity and performance. With Wi‑Fi 7 Multi‑Link for IoT, the ACW741x boosts link reliability with Adaptive Band Switching to mitigate congestion and interference. By maintaining concurrent links across 2.4, 5, and 6 GHz, Wi‑Fi 7 Multi‑Link for IoT delivers a more consistent, always‑connected experience for applications such as security cameras, video doorbells, alarm systems, medical devices, and HVAC systems.

The Infineon ACW741x product family has an optimised 20 MHz design to achieve the industry’s lowest power consumption, and is ideal for battery-operated applications such as security cameras, door locks, and thermostats that require ultra-low Wi-Fi connected standby power. Compared to other IoT Wi-Fi products on the market, the ACW741x offers up to 15x lower standby power consumption, which delivers significantly longer battery life.

The ACW741x also integrates wireless sensing capabilities, which adds contextual awareness to smart IoT devices to create differentiated offerings such as home automation and personalisation. Wi-Fi Channel State Information (CSI) 802.11bf enables enhanced Wi-Fi sensing with intelligence sharing between same-network devices, whereas Channel Sounding delivers accurate, secure, low-power ranging with centimeter-level accuracy.

Combining extensive on-chip integration—including transmit/receive switches, power amplifiers, low-noise amplifiers, power management, and a low-power oscillator—with a QFN package that enables low-cost two-layer PCB designs, the ACW741x provides a cost-efficient migration path to Wi‑Fi 7.
