Infineon Technologies AG has introduced the XDP XDP710 digital controller, the first member of its intelligent hot-swap controller and protection IC family. The hot-swap and system monitoring controller IC provides a 5.5V to 80V input voltage range with transients up to 100V for 500ms. It comprises three functional blocks. The first is the high-precision telemetry and digital SOA control block, optimised to meet the company's power MOSFETs characteristics. The second is the system resources and management block, and the third is the integrated 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 and boost mode. It helps that XDP710 come in small package, easy to design in” said Abhijit Datta, senior power architect and subject matter expert at NVIDIA

“The XDP710 hot-swap controller is a feature-rich device with high-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 and Sensor Systems Division.

The key feature of the controller is its advanced closed-loop SOA control and the fully digital operating mode. This leads to a lower BOM decreasing the external components and design time, providing faster time-to-market. The device can also function in Analog-Assisted Digital Mode to support legacy systems.
