XDP™ Digital hot-swap controller with programmable digital SOA control
Infineon's XDP™ XDP7xx family is the industry’s first wide input voltage range 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.

XDP™ Voltage/Current (V/I) monitoring IC with PMBus
XDP™ XDM700-001 is Infineon’s first high-side or low-side digital V/I/P/E/T monitoring IC with a wide input voltage range up to 80 V. It is suitable for multiple applications such as servers and datacenters, +/- 48 V DC/DC telecom infrastructure, power distribution systems, network routers and switches, power supplies and test equipment.
XDM700-001 provides continuous and reliable monitoring of input and output voltage, input power as well as on-chip and external temperature usind a dedicated 12-bit current and voltage ADC. Together with its 4-level programmable current sense range it enables a telemetry accuracy of ≤1%, while the analog current or power can be reported at AMON pin for post-processing. XDM700-001 incorporates several warnings for a safe and reliable operation and generates various protection responses. Compliance with the industry standard is guaranteed using a PMBus 1.3 interface with up to 1 MHz, thus enabling high-speed communication and a reduced error rate. It comes in a small 4x4 mm2 VQFN-24 package.
