Based on a wide-bandgap material, ON Semiconductor’s 650-V SiC MOSFETs offer improved switching, reliability, and thermals. By replacing existing silicon switching technologies with these silicon carbide devices, designers achieve increased efficiency at the system level, enhanced power density, reduced EMI, and decreased system size and weight.

According to the manufacturer, this generation of SiC MOSFETs employs a novel active cell design combined with advanced thin-wafer technology, enabling best-in-class figure of merit for a 650-V breakdown voltage. The NVBG015N065SC1, NTBG015N065SC1, NVH4L015N065SC1, and NTH4L015N065SC1 N-channel MOSFETs have one of the lowest RDS(on) ratings (12 mΩ) in the market in D2PAK-7 and TO-247 packages.

An internal gate resistor eliminates the need to slow down devices artificially with external gate resistors. And high surge, avalanche, and short-circuit robustness all contribute to enhanced MOSFET ruggedness. The AEC-Q101-qualified devices are well-suited for such applications as electric vehicles, onboard chargers, solar inverters, server power supply units, and uninterruptible power supplies.

Budgetary pricing of the MOSFETs is between $13.66 and $13.99 each.

Compliant with USB power delivery 3.0, the STEVAL-USBPD27S from STMicroelectronics is a 27-W AC/DC adapter reference design with PPS support. It accelerates the design of efficient power adapters with zero-power operation when no cable is connected. USB PPS, a supplemental programmable power supply specification to USB PD, helps save power by reducing device-charging times and heat dissipation.

The STEVAL-USBPD27S combines the STM32G071 microcontroller, which includes an on-chip USB Type-C PD controller, with the STCH03 PWM controller and TCPP01-M12 USB Type-C protection IC. Designers can quickly build fast-charging USB power adapters that meet stringent European CoC Version 5 Tier-2 and US DOE Level VI requirements for minimum four-point average efficiency in active mode and standby power below 40 mW.

As an MCU-based reference design, the STEVAL-USBPD27S offers the flexibility to implement additional customized application layers and to incorporate ongoing improvements as the USB PD standard evolves. Delivered as a turnkey evaluation module in a compact 59×35×21-mm outline, the STEVAL-USBPD27S achieves a power density of 10.2 W/in3.

The STEVAL-USBPD27S reference design costs $95.

Companies providing tools for software developers and quality assurance teams are joining hands with functional safety platforms to automate software analysis and verification, and one such announcement came at the Embedded World 2021 Digital show.

LDRA, which helps developers test safety- and security-critical applications much earlier in the development process, has announced its tool suite’s integration into the Synopsys DesignWare ARC MetaWare Development Toolkit for safety. So, automotive software developers implementing functional safety using Synopsys DesignWare ARC processors can perform system-level testing either on the host platform or the actual target.

LDRA’s test and lifecycle solution for Synopsys functional safety processors and development kits provides designers with lifecycle traceability as well as source code’s static and dynamic analysis. “Our toolkit’s integration into Synopsys function safety development toolkit helps automotive industry software developers from requirements to verification,” said Jim McElroy, VP of sales and marketing at LDRA Technology.

LDRA has signed a similar collaboration pact with PTC to streamline software engineering and quality analysis in its product lifecycle management framework Windchill RV&S. “This integration enables software developers to create safety-critical applications, test application, analyze code, and present that information up in the Windchill product,” McElroy said.

The LDRA tool suite and Windchill RV&S product integration is enabled by the LDRA TBmanager, which employs a rule-based approach for traceability and verification activities. The combined solution automates the software analysis and verification and provides bidirectional traceability from requirements to source code.

The markets that Windchill RV&S serves include automotive, medical, and some industrial, defense, and aeronautics applications. “LDRA toolkit facilitates automation, efficiency and productivity, so Windchill users can test their software, collect results, and put it back in the framework,” McElroy added.

The above tie-ups between toolkits are particularly important in today’s collaborative world where all information is available in the cloud, and people need to share that information. It’s also interesting to see how software has become a collaborative approach across the globe from a development perspective.
