Infineon expands power path protection portfolio
Infineon has launched its 48Volt smart eFuse family and a reference board for hot-swap controllers for 400V and 800V power architectures in AI data centres. This enables developers to design a reliable, robust and scalable solution to protect and monitor energy flow.
“To ensure high reliability, availability, density, and design simplicity in AI data centres, advanced power protection solutions such as eFuse and hot-swap controller functionality are vital, as downtime is directly impacting revenue, customer satisfaction, and operational efficiency,” says Magdalene Boebel, SVP and business line head of power system IC at Infineon.
Infineon says its new eFuse ICs XDP730, XDP720, and XDP721/22 are a critical component in 48V power delivery systems of current AI data centre. The eFuses are designed to protect against overcurrent and other power-related faults ensuring a reliable and efficient power flow from grid to core.
They integrate a digital protection controller, an OptiMOS FET, a gate driver, and a current sensor, and enable hot-swapping while the system is still powered on and operating.
In higher voltage systems of 400V and 800V hot-swapping becomes more difficult because of its high energy demand. That is why Infineon has launched the REF_XDP701_4800 hot-swap controller reference design optimised for future 400V / 800V rack architectures.
The reference design is based on the XDP hot-swap controller. In combination with Infineon’s 1200V SiC JFET technology, the digital hot-swap controller allows to control the device in a linear mode which lets the power system run safely and reliable without being damaged or degraded in case of over voltage events.
Infineon says its new hot-swap controller reference board enables designers to program the optimal trajectory for controlling the inrush current based on the device’s SOA (Safe Operating Area), delivering a nominal Thermal Design Power (TDP) of 12 kW.
