Infineon Technologies AG, a global leader in semiconductor solutions, has made headlines with the expansion of its power path protection portfolio. The company introduced a family of 48 Volt smart eFuses along with a reference board tailored for hot-swap controllers designed for 400V and 800V power architectures. These innovations are specifically crafted to meet the evolving demands of AI data center infrastructures, optimizing reliability, scalability, and energy flow monitoring capabilities.
As AI workloads surge, they substantially elevate data center power requirements. Infineon’s latest offerings tackle the urgent need for robust power protection across varied voltage ranges—starting from 48V systems and extending to advanced high-voltage architectures operating at ±400V and 800V. The introduction of smart eFuses and hot-swap controller technology empowers data center operators and system designers to protect their infrastructures, minimize downtime, and lower total cost of ownership (TCO) in increasingly complex high-performance computing environments.
Meeting the Demands of AI Data Centers with Smart Power Protection
Magdalene Boebel, Senior Vice President and Business Line Head of Power System IC at Infineon, highlighted the significance of advanced power management in AI data centers:
“Ensuring high reliability, availability, and design simplicity is essential in AI data centers where any downtime directly affects revenue, customer satisfaction, and operational efficiency. Infineon’s comprehensive portfolio of power protection solutions empowers system designers to build next-generation AI infrastructures with maximum uptime and optimal performance.”
Infineon’s smart eFuse integrated circuit (IC) family, including models XDP730, XDP720, and XDP721/22, is specifically engineered for 48V power delivery systems, commonly utilized in contemporary AI data centers. These eFuses offer swift and effective protection against overcurrent, short circuits, and other power faults, guaranteeing reliable power flow from grid to core components. By combining a digital protection controller, OptiMOS
FET, gate driver, and current sensor, these eFuses facilitate hot-swapping functionality, allowing IT and power equipment to be connected or disconnected without shutting down the system.
Infineon’s smart eFuses, equipped with programmable real-time telemetry, provide detailed monitoring of voltage, current, energy consumption, and power metrics. This functionality enables predictive maintenance and enhances system diagnostics, a crucial aspect as data centers strive for operational efficiency and reliability.
Innovative Hot-Swap Controller Reference Design for 400V and 800V Architectures
Navigating the complexities of hot-swapping in high-voltage systems operating at 400V and 800V poses significant challenges due to the considerable energy demands. To counter this, Infineon has launched the REF_XDP701_4800 hot-swap controller reference design, optimized for future rack-level power architectures.
This reference design leverages Infineon’s proven XDP hot-swap controller, coupled with the rugged 1200V-rated CoolSiC JFET technology. This combination fosters an optimal balance of low on-resistance (RDSon) and robustness, ensuring safe and reliable linear mode operation during overvoltage events without compromising the device or the system’s integrity.
Additionally, the simplified design minimizes component count while promoting efficient power delivery, rendering it suitable for AI data centers that prioritize high reliability and reduced downtime. The reference board caters to engineers seeking customization for the inrush current control trajectory based on the device’s Safe Operating Area (SOA), accommodating a nominal Thermal Design Power (TDP) of up to 12 kW.
Driving Sustainable, High-Performance AI Data Centers
With its expanded power protection solutions, Infineon plays a pivotal role in enhancing server uptime, reducing operational expenses, and extending equipment lifespan—integral elements for sustainable AI data center ecosystems. By forging close collaborations with leading industry partners and customers, Infineon ensures its solutions adapt to the dynamic needs of AI data centers globally.
As AI workloads continue to expand, Infineon’s smart eFuses and hot-swap controllers remain at the cutting edge of power management innovation. This empowers data centers to deliver uninterrupted performance while optimizing energy efficiency and reliability.
