6 terms

aec-q100 technical

"has completed AEC-Q100 automotive qualification"

AEC‑Q100 is an industry qualification standard for integrated circuits used in vehicles, specifying a set of stress tests and environmental conditions chips must survive to be deemed reliable for automotive applications. For investors, AEC‑Q100 certification is like a durability and safety stamp — components that pass are more likely to win long-term auto contracts, face fewer recalls, and signal lower supply risk and steadier revenue for suppliers.

sic fets technical

"supports both SiC FETs and IGBTs"

SiC FETs are power field‑effect transistors made from silicon carbide (SiC), a wide‑bandgap semiconductor material. They perform the same switching role as silicon MOSFETs but operate at higher voltages, higher temperatures and with lower conduction and switching losses, so they enable more efficient, faster power conversion in applications like inverters, chargers and motor drives. They are not drop‑in replacements for silicon devices: circuit layout, gate drivers, thermal design and cost considerations differ because of the SiC material and device characteristics.

igbts technical

"supports both SiC FETs and IGBTs"

Insulated-gate bipolar transistors (IGBTs) are semiconductor devices that act like high-power electronic switches, turning large currents on and off to control motors, inverters and other power equipment. They matter to investors because demand for IGBTs grows with electric vehicles, renewable energy, industrial automation and data centers; shifts in adoption, supply or price can directly affect the sales, margins and supply chains of companies that make or rely on them.

asil d technical

"functional safety system designs rated up to ASIL D"

ASIL D is the highest safety classification in the automotive functional-safety standard ISO 26262, applied when a failure could lead to severe harm or death. For investors, ASIL D designation signals that a vehicle component or system must meet the strictest engineering, testing and certification controls, which typically raises development cost, lengthens timelines and affects regulatory risk and liability exposure — much like building a nuclear-grade safety system for a car feature.

emi technical

"Reduced electromagnetic interference (EMI)"

An EMI is a UK tax-advantaged employee share option plan that lets a company grant executives and staff the right to buy shares at a preset price after a vesting period. It matters to investors because it aligns employees’ incentives with company performance—like giving key workers a stake in the business—while potentially diluting existing shareholders and changing future earnings per share when options are exercised.

evtol technical

"electric vertical take-off and landing (eVTOL) systems"

eVTOL stands for "electric vertical takeoff and landing" aircraft, which are small, electric-powered vehicles capable of taking off and landing vertically like a helicopter. They are designed to provide quick, on-demand transportation within cities or between locations, potentially transforming urban mobility. For investors, eVTOLs represent a growing segment of innovative transportation technology with potential for significant market impact and future growth.

Si829x platform with ProVCD™ technology moves from development to pre-production release for EV traction inverters

IRVINE, Calif., Oct. 07, 2026 (GLOBE NEWSWIRE) -- Skyworks Solutions, Inc. (Nasdaq: SWKS), an innovator of high-performance analog and mixed-signal semiconductors, today announced that its Si829x isolated safety gate driver with ProVCD™ technology has completed AEC-Q100 automotive qualification and is ready for advanced prototyping. Samples, tools, user guides, and application notes are available now. Designed for scalable, high-performance inverter architectures, the Si829x supports both SiC FETs and IGBTs while helping customers improve efficiency, simplify system design, and reduce system cost in applications ranging from automotive drivetrains to safety-critical electric vertical take-off and landing (eVTOL) systems.

AEC-Q100 Qualified and Ready for Evaluation

With AEC-Q100 qualification completed, the Si829x is now positioned to support customers for initial product evaluation through pre-production prototypes. Samples are available today, giving customers a qualified, prototype-ready path to design-in.

The Si829x was designed to support customer functional safety system designs rated up to ASIL D, subject to system-level implementation and validation, to deliver the robustness required for EV traction inverters and other safety critical motor control applications. Its integrated protection features include:

• Extensive diagnostic fault coverage, notification and management
• Comprehensive safety mechanisms including power-up self-checks and safe state enforcement – a functional safety manual is available today

With applications in battery electric vehicles, hybrid electric vehicles, eAgriculture, eTrucking, robotaxis, and exciting new segments like eVTOL aircraft, Si829x is a comprehensive choice among isolated gate drivers for safety-critical advanced propulsion systems.

Full Documentation and Development Tools Now Available

Alongside qualification, Skyworks has prepared the complete technical resource set for the Si829x, including datasheet, technical reference manual, functional safety manual and application notes. This resource set, available under NDA, gives design teams comprehensive technical documentation to evaluate, integrate and validate the part.

Skyworks has also released customer-facing development tools, including two evaluation board kits, companion GUI software and complex device driver (CDD) software, designed to shorten development cycles and reduce time-to-market.

A New Approach to Gate Drive Control

Unlike conventional voltage-mode gate drivers, the Si829x uses ProVCD™, which is Skyworks’ second-generation variable current drive that delivers high resolution gate waveform shaping and cycle-by-cycle control through a digital interface. This approach enables:

• Precise 15 Amp 3-phase turn-on and turn-off current waveform control
• Switching-loss reductions of up to 44% in Skyworks testing, compared with voltage-mode gate drive
• Reduced electromagnetic interference (EMI) and filtering requirements
• Improved thermal efficiency through multiple packaging options
• Smaller PCB footprint and potential system-level cost savings
  
  

Together, these benefits allow manufacturers to increase inverter efficiency while simplifying system design and accelerating development cycles.

“Si829x gives customers a qualified path from evaluation to advanced prototypes,” said Mario Battello, vice president of product line management at Skyworks. “The ProVCD™ platform combines software-configurable performance with the safety, isolation and design flexibility needed to standardize inverter designs for EVs, eVTOL, and eAgriculture, and accelerate development for high power motor applications like datacenter cooling and AI power supplies.”

Platform Scalability and Design Flexibility

The Si829x is designed as a configurable platform, allowing engineers to adjust gate drive parameters through software rather than fixed hardware components. This configurability supports:

• Design reuse across multiple vehicle platforms
• Faster development and validation cycles
• Greater flexibility to optimize performance, efficiency and cost
• Vendor-agnostic compatibility across power semiconductor technologies
  
  

By supporting both SiC FETs and IGBTs within a single gate driver platform that integrates a VPOS regulator, bipolar gate drive voltages are provided without the need for additional, external bias supplies.
