XDP™ Digital hot-swap controller with programmable digital SOA control

Infineon's XDP™ XDP7xx family is the industry’s first wide input voltage range digital hot-swap and system monitoring controller IC family designed to meet the reliability and high availability requirements of pluggable Artificial Intelligence (AI) accelerator cards and baseboards (XDP710-002, XDP711-001) as well as a spectrum of telecom and datacom applications including remote radio head power, base station power distribution, and live and passive antenna systems of 5G and telecom UPS (XDP700-002).

The XDP7xx family employs a three-block architecture that combines high-precision telemetry for monitoring and fault detection, digital SOA control optimized for power MOSFETs, and integrated gate drivers for n-channel power MOSFETs. The advanced closed-loop SOA control and the fully digital operating mode of XDP7xx results in lower bill-of-material (BOM) costs due to the minimum number of external components and reduced design time, allowing faster time-to-market. XDP7xx can also support legacy systems in Analog-Assisted Digital Mode. Furthermore, the provided Surge Immunity ensures higher system reliability.
