    Littelfuse Launches FDA117 Optically Isolated Photovoltaic Driver

    2 Min Read

    Littelfuse, Inc. announced the launch of the FDA117 Optically Isolated Photovoltaic Driver. This innovative product generates a floating power source, making it an exceptional choice for isolated switching applications in a wide range of industries.

    The FDA117 is specifically designed to control discrete standard power MOSFETs and IGBTs using a floating voltage source, ensuring isolation between the low-voltage drive input side and high-voltage load output side. With an input control current range of 5 mA to 50 mA, an integrated fast turn-off circuitry, and 5 kVRMS reinforced isolation, the FDA117 provides sufficient voltage and current to drive discrete power MOSFETs and IGBTs effectively.

    One of the key differentiators of the FDA117 is its ability to generate a floating power source with up to 15.3 V voltage and 60 µA current, making it suitable for driving standard MOSFET devices and IGBTs. This feature allows for greater flexibility in application designs, enabling the direct driving of standard MOSFET/IGBT devices and securely turning off external power semiconductors in less than 0.5 milliseconds.

    Product designs that can benefit from the FDA117 include power semiconductor applications in the following markets (to name a few):

    • Industrial
    • Energy
    • Building Automation
    • Smart Home

    Whether it is used in custom solid-state relay designs, controlling electrical power and loads, or industrial process control, the FDA117 provides the necessary isolation barrier to protect equipment and individuals from electrical hazards.

    “To give our customers more flexibility in their application designs, we developed the FDA117 to add a single-channel version to our existing portfolio of Photovoltaic Drivers,” said Mark P. Smith, Director, Product Management, Integrated Circuits & MCU. “High open circuit voltage and short circuit current, combined with 5 kVRMS reinforced isolation voltage, extend the design flexibility.”

    The FDA117 is available in both 4-pin DIP through-hole and surface mount packages, providing pinout compatibility with other Photovoltaic Drivers available on the market. This compatibility ensures ease of integration into existing designs without any major modifications.

    The FDA117 Optically Isolated Photovoltaic Driver includes the following key features:

    • Operates with as low as 5 mA input control current
    • Enables driving standard power MOSFETs and IGBTs
    • Provides a floating output voltage ranging from 10.5 V to 15.3 V
    • Integrated fast turn-off circuitry for controlled switching
    • 5,000 VRMS reinforced insulation for enhanced safety
    • 4-pin surface mount and through-hole package options

    Littelfuse Launches First Automotive PolarP P-Channel Enhancement Mode Power MOSFET

    2 Min Read

    Littelfuse, Inc. announced the release of IXTY2P50PA, the first automotive-grade PolarP™ P-Channel Power MOSFET. This innovative product design meets the demanding requirements of automotive applications, providing exceptional performance and reliability.

    The key differentiator of the –500 V, –2 A IXTY2P50PA is its AEC-Q101 qualification, making it ideal for automotive applications. This qualification ensures that the MOSFET meets the automotive industry’s stringent quality and reliability standards. With this qualification, automotive manufacturers can trust that the IXTY2P50PA will deliver exceptional application performance and reliability.

    One of the standout features is its low conduction loss. With a maximum on-state resistance of 4.2 Ω, this P-Channel Power MOSFET offers reduced power dissipation, decreasing heat generation and improving efficiency in the end applications. Additionally, the MOSFET provides excellent switching performance, with a low gate charge of 11.9 nC, allowing for fast and efficient operation.

    Another key advantage is its ruggedness in demanding operating environments and applications. With its dynamic dv/dt and avalanche rating, this MOSFET can withstand harsh conditions and deliver reliable performance. This combination makes it an excellent choice for automotive applications that require durability and reliability.

    Furthermore, the IXTY2P50PA high-voltage automotive P-channel MOSFET enables a power-dense PCB design, thanks to its miniature TO-252 (DPAK) footprint in surface mount form factor. This compact footprint results in significant space savings on the PCB, allowing for more efficient and compact designs. Automotive manufacturers can benefit from this space-saving design, enabling them to optimize their applications and achieve greater functionality in limited space.

    The PolarP Series is ideally suited for a range of automotive electronics and industrial applications, including:

    • Automotive ECUs
    • Automotive sensor circuits
    • High-side switches
    • Push-pull amplifiers

  • Elmos Sale of Dortmund Wafer Fab to Littelfuse

    Elmos: Sale of Dortmund Wafer Fab to Littelfuse

    3 Min Read

    Elmos Semiconductor SE, one of the world’s leading suppliers of mixed-signal automotive semiconductors, and Littelfuse, Inc., USA, entered into a definitive agreement on the sale of the Elmos wafer fab at the Dortmund site to Littelfuse. Elmos has agreed to sell the wafer fab at a net purchase price of approximately 93 million Euro. Under the agreement, Littelfuse will acquire the Dortmund wafer fab with a highly skilled technology team of approximately 225 employees. All other activities, including testing operations, will remain with Elmos.

    In acquiring the Dortmund wafer fab, Littelfuse enhances its capabilities in power semiconductors for high-growth power conversion applications like renewables, energy storage, and e-Mobility charging infrastructure.

    “Today’s agreement is a milestone for semiconductor production in Dortmund and it will strengthen Germany’s standing as a high-tech location. As a fabless company, Elmos will make even greater use of advanced technologies to deliver groundbreaking innovations in mixed-signal semiconductors. Elmos is already the global market leader for certain applications in the automotive industry. We want to use this strong position to shape our future growth,” says Dr. Arne Schneider, CEO of Elmos Semiconductor SE.

    Headquartered in Chicago, Illinois, United States, Littelfuse, Inc. is a diversified, industrial technology manufacturing company empowering a sustainable, connected and safer world. The company operates across more than 20 countries, and with approximately 18,000 global associates. Its products are found in a variety of industrial, transportation and electronics end markets. In Germany, Littelfuse operates various manufacturing, sales and R&D sites.

    The closing of the transaction is expected to be effective December 31, 2024, and is subject to certain closing conditions and regulatory approvals, among them the investment control procedure under foreign trade law conducted by the German Federal Ministry for Economic Affairs and Climate Action. Elmos will retain full operational control over the wafer fab until the closing date.

    In addition, Elmos and Littelfuse have agreed to enter into a defined multi-year capacity sharing arrangement with an initial term lasting through 2029, with Elmos buying defined volumes of wafers produced at the fab. This long-term agreement supplements the existing supply arrangements with Elmos’ other foundry partners and ensures that Elmos has the necessary capacities to meet projected customer demand.

    “This is good news for the Elmos wafer fab team. We are delighted for Littelfuse to further develop the wafer fab in Dortmund for power semiconductors. Our employees are now expecting a quick review procedure by the relevant authorities,” says Dr. Schneider.

    Following regulatory approvals of the transaction, the buyer will make a payment of approximately 37 million Euro. The remainder of the purchase price will be paid at closing. The transaction has no major effects on EBIT in fiscal year 2023, which is why the current forecast for the full-year EBIT margin in 2023 (25% ± 2 percentage points) continues to apply.

    Cash flow is expected to be positively influenced in fiscal year 2023 by the payment of approximately 37 million Euro after regulatory approvals. Irrespective of the transaction, Elmos continues to increase its efforts to expand testing capacities for future growth. The company now anticipates capital expenditures of approximately 19% ± 2 percentage points of sales in fiscal year 2023 (previously: 17% ± 2 percentage points). As a result, Elmos now expects a negative operating adjusted free cash flow in 2023.
