Infineon introduces the industry's first wide voltage, programmable digital SOA controlled hot swap controller

     The continued demand for artificial intelligence (AI) services in high performance computing (HPC) data centers is driving the growth of the market in this segment. Dedicated AI accelerators can help dramatically improve the performance and efficiency of these data centers. As with many critical infrastructure systems, reliability and high availability are essential to these data centers, but extremely difficult to achieve. Developers of AI supercomputing platforms have faced these demands by resorting to hot-plug solutions that monitor power and protect systems even when components are hot-plugged.

     Infineon Technologies AG is responding to these challenges with the XDP XDP710 digital controller, the first product in Infineon's Intelligent hot-swap controller and Protection Circuit (IC) family. The hot swap system monitor controller IC has an input voltage range of 5.5V to 80 V with transient voltages up to 100 V and lasting 500 ms. It consists of three functional modules: the first is a high precision telemetry and digital secure Workspace (SOA) control module optimized to meet the characteristics of Infineon power MOSFET; The second is the system resources and management module; The third is an integrated grid driver and charge pump module for n-channel power mosFeTs such as OptiMOS and StrongIRFET series.

     "Infineon Technologies' XDP710 digital Hot-swap controller is well suited to the product needs of the HGX platform," said Abhijit Datta, senior Power Architect and domain expert at NVIDIA. The XDP710 offers unique features such as the option to select an external MOSFETs by side-by-side resistors and to start a rise mode. The XDP710's small size and ease of design helps us."

     "The XDP710 Hot Plug controller is a feature rich product with a high-precision analog front end and integrated health monitoring, telemetry, programmability and preset MOSFET SOA," said Shahram Mehraban, vice president, Power Management IC Business, Infineon Technologies' Power and Sensing Systems Business Group. It addresses the design challenges associated with current pluggable AI server solutions."

     The key features of the XDP710 controller are its advanced closed-loop SOA control and full digital operation mode. This not only reduces material BOM costs, but also reduces the number of peripheral components and design time, thus accelerating product to market. The XDP710 also supports analog - assisted digital mode for traditional systems.
