STMicroelectronics has announced two new high-speed half-bridge gate drivers that bring gallium-nitride (GaN) efficiency, thermal performance, and miniaturization to a broad range of power and motion-control applications. The STDRIVEG212 and STDRIVEG612 deliver tightly controlled 5V gate-drive signals to enhanced-mode GaN HEMTs, powered from a high-side voltage up to 220V or 600V respectively. The drivers are highly integrated, with high-side and low-side 5V linear regulators (LDOs), a high-side bootstrap diode, and protection including under-voltage lock-out (UVLO), in a compact QFN package. An integrated fast-startup voltage regulator stabilizes the supply voltage for the driver output stage, ensuring consistent gate control, while an embedded comparator turns off both GaNs on detecting overcurrent. Smart shutdown (SmartSD) automatically holds the switches off long enough to cool down and a fault pin provides overcurrent, overtemperature and UVLO reporting. The drivers are featured to maximize the benefits of GaN technology, particularly in hard-switching applications such as motion control. The propagation delay of just 50ns is closely matched between high side and low side, with high-side start-up time of 5µs and ±200V/ns dV/dt transient immunity, permitting high rotational speeds. The integrated LDOs have high current capability and provide separate sink and source paths, sinking up to 1.8A/1.2Ω, and sourcing 0.8A/4.0Ω. The gate driver output architecture lets designers differentiate the turn-on and turn-off impedance to optimize dV/dt and dI/dt and thereby avoid using turn-off diodes. This permits a lower bill of materials, reduced gate-loop inductance, and faster turn-off with increased margin to prevent unwanted induced turn-on. With 20V-tolerant logic inputs and a dedicated shutdown pin to save power during inactive periods, the STDRIVEG212 and STDRIVEG612 ease system design and integration. The EVLSTDRIVEG212 evaluation board is suitable for both devices and is available now.The STDRIVEG212 and STDRIVEG612 are industrial-grade devices, qualified to operate from -40°C to 125°C. Both are in production now and available in a 4mm x 5mm QFN package, priced from $1.25 for orders of 1000 pieces.For more information, please visit Innovative GaN gate drivers for advanced efficiency & reliability Additional resources Product overview - EVLSTDRIVEG212 Product overview - STDRIVEG212 Datasheet - STDRIVEG612 eStore - STDRIVEG612QTR eStore - STDRIVEG212 eStore - EVLSTDRIVEG212 First published on Apr 01, 2026

The devices target space-constrained applications including power distribution and battery management in automotive products. The first device in the new series, the STL059N4S8AG, is a 40V/420A N-channel enhancement-mode MOSFET with RDS(on) 0.59mΩ, housed in a PowerFLAT 5x6 package. The compact outline saves PCB space, easing the design of smaller control modules, while high thermal conductivity and efficient dissipation help meet stringent reliability targets. The devices also have an extended maximum operating temperature of 175°C. The STL059N4S8AG is available as an AEC-Q101 qualified part in a package with wettable flanks that facilitates optical inspection in automotive assemblies. ST’s Smart STripFET F8 technology builds on the conventional STripFET F8 with a modified trench gate that enhances on-state performance and silicon-area efficiency.  These devices are optimized for applications where minimizing conduction losses is key to improving overall efficiency. They are particularly well suited for high-current power distribution, where the devices combine effectively with STi²Fuse VIPower gate drivers that offer tunable circuit breaking to safeguard PCB traces, connectors, and wiring. In automotive applications, Smart STripFET F8 MOSFETs efficiently deliver more of the battery’s energy to on-board electrical systems while reducing power dissipation, thereby contributing to extended driving range. In a battery-management system (BMS), where the main functions are monitoring cell states, balancing, and protection, the MOSFETs’ lower RDS(on) enhances efficiency during battery charging and discharging. The STL059N4S8AG is in production now, in automotive grade. Please contact your local ST sales office for pricing and sample requests. The STL075N4S8AG with 350A current rating and 0.75mΩ RDS(on), and the STK035N4S8AG with 780A and 0.35mΩ will be introduced later.

Designers can choose from two variants, configured for forced-PWM operation for optimal performance in noise-sensitive applications, or pulse-skipping for minimal power consumption at light load. Both variants implement frequency dithering, to reduce noise power at the switching frequency, and have extremely low quiescent current of 85µA to minimize overall power consumption. An Enable pin allows the converter to be turned off to maximize power savings. A dedicated evaluation board, STEVAL-3603BC1, is available to help quickly evaluate the DCP3603 in new designs. The board has a compact footprint and is quickly connected with screw terminals and headers, ready to power-up out of the box. The DCP3603 is in production now, in a SOT23 6-lead package, priced from $0.44 for orders of 1000 pieces. For further information please visit: Advanced synchronous buck converters.

Introduction Building on the solid foundation of STM32CubeMX, STM32CubeMX2 takes the STM32 development experience to the next level. It enhances proven functionalities and introduces new features to deliver greater efficiency, flexibility, and innovation from its very first release. Coexistence with STM32CubeMX: STM32CubeMX and STM32CubeMX2 will coexist. STM32CubeMX2 is introduced for new STM32 series, starting with STM32C5. Future ready workflows: STM32CubeMX2 continues to streamline existing workflows while opening the door to more advanced capabilities. Active evolution: ST will keep enhancing STM32CubeMX2 with regular fixes and new features over time. live code preview for faster prototyping The new live code preview in STM32CubeMX2 accelerates prototyping for developers who use STM32CubeMX as a code snippet generator: No need to generate full projectsGet the initialization code directly in the STM32CubeMX2 live code preview window, ready to paste into your existing project. Instant feedbackAny change in the configurator is immediately reflected in the code preview, so you can track updates in real time. Diff view for clearer understandingA built-in diff function shows how configuration changes impact the generated code, helping you understand updates at a glance. Highlight Path: clearer clock configuration Tracing clock signals with your finger on the screen is no longer necessary. In STM32CubeMX2, the Highlight Path feature shows: Which peripherals depend on a given clock Which clock a specific peripheral is running on In addition, a new table view provides a simple, organized display of all clocks, making it much easier to understand and manage your clock configuration. Pinout table view for faster, clearer configuration On the configuration side, the new pinout experience boosts productivity with: Enhanced pin search Clear highlighting of alternative pins for a given I/O A table view that makes assignments easier to review and adjust These improvements help shorten time to market while keeping project dependencies and configuration under control. The optimized graphical interface makes it easier to identify the right pin for your design, enabling hardware and software teams to collaborate more efficiently and get projects ready faster. GUI updates for a smoother experience The new and enhanced user interface is designed to make your workflow more intuitive and efficient. By prioritizing easy access to the most frequently used and straightforward settings, it streamlines the journey from concept or datasheet to a working prototype—so you can focus on what matters most. With a new quick menu, you’ll never miss an important setting. It ensures you can always find what you’re looking for, even when navigating more complex features, making your workflow smoother and more efficient. STM32CubeMX2 documentation goes online Instead of relying on static PDF files, STM32CubeMX2 now features a brand-new online documentation portal, ensuring you always have access to the latest, most up-to-date information. The portal also provides direct links to articles, application notes, and related resources, helping you achieve more in less time. New pack manager to keep projects up to date STM32CubeMX2 introduces packs to automatically manage dependencies when building a project. This makes it easier to: Keep your projects aligned with the latest software versions Add middleware or hardware components as needed Generate code based on LL or HAL2, the new hardware abstraction layer deployed with new STM32 series starting from STM32C5 STM32CubeMX2 also supports multiple project output formats to match your toolchain strategy, including: STM32CubeIDE CMake-based workflows (such as VS Code and other IDE/compiler environments) Partner IDE formats, including IAR and Keil Studio Known limitations This first STM32CubeMX2 release is a major milestone in our roadmap. We are aware of some current limitations, but we wanted to deliver these new capabilities to you as early as possible. The tool is fully functional, and its output can be safely used for production software. Regular patches and feature updates are already planned to improve the experience. The most visible gaps today relate to performance with large configurations, some IDE/toolchain and regeneration workflows that still require manual steps, and the fact that it is not yet possible to lock a specific component version. Performance Large projects or MCUs may feel slower than expected.Ongoing optimizations are targeting improved responsiveness and scalability. Packs and middleware Pack import and compatibility visibility are still improving; some legacy packs may not be configurable. Currently, FreeRTOS is the only supported middleware. Other middleware components will be added over time. IDEs, toolchains, and regeneration STM32CubeMX2 cannot track changes made manually to project files outside the tool. Manual edits done in the IDE can be overwritten when regenerating the project—this is particularly true for IAR, where the entire project is contained in a single file that STM32CubeMX2 replaces. To mitigate this risk, we strongly recommend: Using a version control system Enabling the available settings to back up user files during project generation Configuration and user experience Some workflows are still more complex than desired. Certain conveniences—such as centralized privilege management or flexible init ordering—are not yet available. Project generation and files Some generated artifacts follow fixed conventions (for example, file locations). Certain defaults (such as GPIO speed) may need manual adjustment depending on peripheral requirements. Hardware parts / start from board Hardware-part coverage and board-default activation are currently more limited than our long-term target. Installation and updates STM32CubeMX2 does not self-update. Upgrades can require a reinstall, and parallel installations are not supported. We plan to deliver quarterly releases to expand device and middleware support, improve UX and performance, and progressively close these known gaps. For the most up to date list of known limitations, please refer to the online documentation portal.

MIS2DU12 MEMS accelerometer combines ultra-low power, signal processing, and an ultra-low profile suitable for wearable and implantable medical applications. Produced using biocompatible materials and manufacturing processes, the MIS2DU12 has a 20nA power-down and sub-1µA active mode to extend the operating envelope of implantables such as cardiac monitors and pacemakers. At only 0.74mm high, and 2mm x 2mm, it enables skin patches to become extremely slim, lightweight, and comfortable to wear. In skin patches such as glucose monitors and other bio-parameter sensors, the MIS2DU12’s ensures precision even during macroscopic motion and environmental stress. The applications benefit from high micro-motion sensitivity, power efficiency. The dedicated internal engine for motion processing detects free-fall, wake-up, single/double-tap, activity/inactivity, and calculates 6D/4D orientation. There are also built-in self-test and an embedded temperature sensor. With integrated motion processing for event detection and wake-up, the MIS2DU12 contains an anti-alias filter to maximize output-data quality. By removing out-of-band vibration sources, this filter offloads the main application processor to help cut system power consumption. The sensor draws just 0.47μA in ultra-low-power active mode with 1.6Hz output data rate, and 5.6µA in normal operation with the anti-alias filter enabled. The MIS2DU12 has user-selectable full scales of ±2g/±4g/±8g/±16g, output data rates from 1.6Hz to 800Hz, and operates over the extended temperature range from -40°C to +85°C. An integrated 128-level FIFO buffer provides generous data storage and extra flexibility to save system power consumption. For rapid evaluation, the STEVAL-MKI255A adapter board contains a MIS2DU12 sensor and has a standard DIL24 pin arrangement for use with the STEVAL-MKI109D evaluation board. The board includes a high-performance 32-bit microcontroller and is ready to use with ST’s MEMS Studio GUI. The MIS2DU12 is in production in the 2.0mm x 2.0mm x 0.74mm plastic land grid array (LGA) package and available by the end of H1 2026 from $9 for orders of 1000 pieces. An evaluation board, the STEVAL-MKI109D, is also available. For more information visit Ultralow-power accelerometer with antialiasing and motion detection.
