The importance of hot-swapping in the AI era

Reduced downtime in AI factories and data centers

Hot-swapping has become a critical feature for data centers and AI servers, where downtime is costly and reliability is paramount. This functionality enables the replacement of faulty components, like AI blades or power supplies, without powering down the system. However, this comes with its own challenges, including inrush currents that can damage sensitive electronics and destabilize the power grid. Infineon addresses these challenges through innovative solutions that ensure MOSFETs stay within their Safe Operating Area (SOA) during hot-plug events, mitigating risks to critical components. For example, Infineon’s hot-swap controllers eliminate debounce effects and prevent voltage spikes, ensuring system stability even during high-power transient events. These systems are especially vital in modern AI servers operating at 8 kW to 12 kW, where uninterrupted power delivery is critical for processing bandwidth-intensive workloads.

Infineon’s portfolio and know-how ensure safe and efficient hot-swapping, unlocking this cornerstone of reliable data center infrastructure.

Hot-swap controllers

Infineon’s XDP™ digital hot-swap controllers are designed to ensure safe and reliable operation in high-availability systems, such as AI servers and data centers. With advanced digital Safe Operating Area (SOA) control, XDP™ hot-swap controllers protect against inrush current and fault conditions, allowing server blades to be inserted and removed without shutting down the system. This minimizes downtime and ensures continuous operation of critical workloads.

Equipped with high-precision analog front-end components and PMBus telemetry, our hot-swap controllers enable accurate real-time monitoring and reporting of power and energy usage. This empowers operators to optimize system efficiency, reduce energy consumption, and improve reliability by monitoring server racks individually. Used in conjunction with OptiMOS™ LinearFET 2 linear MOSFETs, featuring low RDS(on) and strong SOA performance, Infineon provides scalable and robust protection for demanding environments.

Linear MOSFETs

Infineon’s OptiMOS™ 5 Linear MOSFET 2 family of advanced MOSFETs provides high-performance solutions designed to meet the demands of hot-swapping in modern data centers and AI servers. These devices combine excellent thermal efficiency with precise current and voltage control, ensuring robust operation in high-power systems. They are optimized for use in hot-swap applications, where scalability and reliability are critical. LinearFET 2 MOSFETs are a key component in regulated 48 V to 12 V power conversion solutions, which are widely used in data centers. They ensure efficient power delivery, even at higher loads, while maintaining system stability. LinearFET 2 MOSFETs are also ideal for next-generation 48 V server backplanes, which reduce energy losses, increase power density, and improve system scalability. When paired with Infineon’s XDP™ hot-swap controllers, they create a seamless power management solution for demanding environments, enabling infrastructure that is both efficient and future-ready.

Hot-swap in the future

As data centers evolve, the need for compact, efficient, and reliable power management solutions grows. Infineon is at the forefront of this evolution with innovations such as eFuses—programmable circuit protection devices that replace traditional fuses with advanced features. These include precise overcurrent, overvoltage, and thermal protection, all of which increase safety and simplify design. eFuses are reusable and compact, making them ideal for today’s high-density server designs. Additionally, the trend toward 48V backplane architectures in data centers is gaining momentum, as they reduce power conversion losses and improve scalability. Infineon’s integrated solutions, which combine eFuses with XDP™ digital controllers, provide exceptional performance for high-power systems like 8 kW and 12 kW AI servers. By enabling higher power densities and increased efficiency, these technologies set the stage for the next generation of data center infrastructure, delivering unparalleled reliability and scalability.
