L4983 power-factor correction (PFC) controller contains a proprietary multiplier emulator and distortion-optimization circuitry, letting designers build continuous conduction mode (CCM) PFC circuits with very few external passive components. The L4983 is suitable for power supplies ranging from several hundred Watts to multiple kilowatts and has a totem-pole output with 0.7A source/1.5A sink capability. Typical applications include industrial and medical power supplies, high-power luminaires, servers, PCs, and home electronics that must meet EN 61000-3-2 and similar specifications worldwide, such as the Japanese JEIDA-MITI standard.The device has three power-saving modes that help equipment meet efficiency guidelines including US Energy Star, the EU Ecodesign Directive, and European Code of Conduct for power adapters. Among these, burst mode automatically stops switching activity during light or zero load conditions, resuming quickly without soft-restart as the load increases. Addition

L9962 lithium-battery management IC delivers superior precision by integrating a 12-bit analog-digital converter (ADC), coupled with generous cell-balancing current of 70mA, to ensure rapid voltage correction for improved battery health. Designed for lithium-ion (Li-ion) and lithium-polymer (Li-Po) battery packs with up to 10 series-connected cells, the L9962 provides monitoring, balancing, and protection to optimize performance and enhance safety and stability. It is suitable for cordless power tools and other portable and semi-portable equipment, including medical devices, light electric vehicles like e-bikes and scooters, and backup energy storage such as UPS. Its ultra-low quiescent current maximizes runtime and permits power-saving modes including 5µA standby and 2µA deep-sleep for products in transit. The L9962 measures individual cell voltages on a continuous cycle with programmable loop time and activates balancing and cell protection upon detecting overvoltage or undervoltage.

If you’re building AI-powered applications on STM32, you can now access all the ST Edge AI documentation you need from one place: ST Edge AI Documentation.The new documentation hub brings together reference material, how-to guides, and tutorials that were previously spread across separate tool pages and older wiki articles.Instead of jumping between sources, you can start from one entry point.Key benefits:Find answers faster: search across ST Edge AI tools from one place instead of checking multiple pages. Follow complete workflows: use new tutorials that walk you through end-to-end development steps that were not previously documented in one flow. Work with the right version: access documentation that stays aligned with the tool releases it supports. Use AI assistants more reliably: the Copy for LLM option lets you provide the actual documentation pages to an AI assistant, helping it answer from the source rather than guessing. Keep your focus on development: the hub is dedicated to o

Security is now a core part of product development. The EU’s Cyber Resilience Act (CRA) and Radio Equipment Directive (RED) have set mandatory cybersecurity and safety standards for connected digital and radio devices. The CRA is a new EU law requiring connected digital products to meet strict cybersecurity standards throughout their lifecycle, protecting users and reducing cyber risks. The RED is an EU regulation ensuring radio and telecom devices are safe, free from harmful interference, and equipped with essential security features for reliable wireless communication. As developers, integrating these requirements early helps build secure, reliable products that protect users, avoid costly penalties, and maintain market access. These regulations are designed to close security gaps early in the product lifecycle, ensuring devices are secure by design, regularly updated, and capable of resisting attacks. Non-compliance not only risks user safety and data integrity but can also lead to

In smart manufacturing and industrial Internet of Things (IoT), vibration monitoring has become a critical enabler of predictive maintenance, anomaly detection, and operational efficiency. As systems become more connected and data-rich, developers face a familiar challenge: how to add more intelligence without increasing power consumption, cost, or design complexity.With Intelligent Sensor Processing Unit (ISPU) 2.0, ST introduces a new way to build sensing systems. Instead of treating the sensor as a passive data source, ISPU 2.0 turns it into an intelligent edge node that can execute signal-processing and artificial intelligence and machine learning (AI/ML) workloads directly where the data is created. The first product to showcase this approach is IIS3DWB10IS, a high-performance MEMS vibration sensor that combines ultrawide bandwidth, high dynamic range, and ultralow noise with in-sensor processing capabilities for real-time analytics at the edge. A new model for smart sensingTradit

L6462A transition-mode (TM) power-factor correction (PFC) controller cuts bill-of-materials (BOM) costs while enhancing efficiency, enabling consumer products and power supplies up to 250W to meet stringent eco-design norms.  The L6462A uses a current generator and shaper to produce a sinusoidal reference, instead of a conventional voltage sensor and analog multiplier, permitting boost-PFC converters without external voltage-divider components. In addition, the IC coordinates the PFC conversion cycles by sensing inductor demagnetization via the gate-driver output and hence requires no auxiliary inductor winding or interface components. In addition to lowering BOM, the L6462A’s innovative current shaping and demagnetization sensing minimizes distortion (THD) and enhances efficiency, particularly at intermediate and light loads. The new controller thus permits economical PFC with superior performance, targeting high-end battery chargers, power adapters, and power supplies for domestic an

Connecting multiple ICs permits even larger arrays of up to 31 battery packs with a total of 434 series cells. Coulomb counting inside the L9963F supports pack overcurrent detection in both ignition on and off states. A fully redundant cell-measurement path, with ADC swap, provides enhanced safety and enables limp-home functionality. The L9963F can take its power from the monitored battery and integrates circuitry to generate stable internal references and ensu

STMicroelectronics has introduced two 100-Watt VIPerGaN high-voltage converters, extending wide-bandgap energy savings throughout domestic appliances, building and home automation, smart lighting, and consumer products including televisions and device chargers. The new converters include the VIPerGaN100W, with 3.5A drain current limit, while the VIPerGaN100WB has a 4.2A current limit for handling short-term peak power up to 125W. The extra flexibility saves designers over-specifying power circuitry in equipment containing inductive loads like solenoid valves or motors, such as in coffee makers, small appliances, and air-conditioners. Both converters are compatible with the universal AC input voltage range, from 85V to 265V, and will deliver 100W from 185V supply. The 700V gallium-nitride (GaN) power transistor in each converter ensures ruggedness and reliability, with extremely low RDS(on) of 0.27mΩ that helps achieve great thermal performance. The 5mm x 6mm QFN devices also integrate
