Infineon introduces the industry’s first wide voltage range hot-swap controller with a programmable digital SOA control for data centers

Date: 14/11/2022
Continued demand for Artificial Intelligence (AI) services in High-Performance Computing (HPC)data centers is driving the market growth in this segment. Special-purpose AI accelerators facilitate a significant increase in the performance and efficiencyof these data centers. Like in many critical infrastructure systems, reliability and highavailability are essentialand highly challenging. Developers of AI supercomputing platforms can only address these requirements with hot-swap solutions that monitor the power supply and protect the system even when components are hot-swapped.

Infineon Technologies AG tackles these challenges by introducing theXDP XDP710 digital controller, the first member of its intelligent hot-swap controller and protection IC family.The hot-swap and system monitoring controller IC has a 5.5Vto80V input voltage range with transients up to 100V for 500 ms. It consists of three functional blocks. The first is the high-precision telemetry and digital safe operating area (SOA)control block, optimized to meet Infineon’s power MOSFETs characteristics. The second is thesystem resources and management block, and the third is theintegrated gate driver and charge pump block for n-channel power MOSFETs such as OptiMOS and StrongIRFET families.

“Infineon Technologies’ XDP710 Digital hot-swap controller met HGX Platform product requirement well. Like its unique features such as option of external FET selection using resistor strapping andboost mode. It helps that XDP710 come in small package, easy to design in” said Abhijit Datta, Sr. Power Architect and Subject Matter Expert at NVIDIA

“The XDP710 hot-swap controller isa feature-richdevice withhigh-precision analog-front-end along with comprehensive health monitoring, telemetry, programmability, and pre-set MOSFET SOA. It addresses the challenges associated with the current design of pluggable AI server solutions,” said Shahram Mehraban, Vice President Power Management ICs at Infineon’s Power & Sensor Systems Division.

The key feature of theXDP710 controller is its advanced closed-loop SOA control and the fully digital operating mode. This leads toa lower bill-of-material (BOM)reducing the number of external components and design time, allowing faster time-to-market. The XDP XDP710 can also operate in Analog-Assisted Digital Mode to support legacy systems.

The XDP XDP710 digital hot-swap and system monitoring controller IC is in production and available in a 29-lead (6 x 6 mm˛) VQFN package. More information is available atwww.infineon.com/xdp710-001.
