Infineon claims first wide voltage range hot-swap controller with programmable digital SOA control 

Infineon Technologies 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 has a 5.5V to 80.0V input voltage range with transients up to 100.0V for 500ms. It consists of three functional blocks. The first is the high-precision telemetry and digital safe operating area (SOA) control block, optimised to meet Infineon’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 the OptiMOS and StrongRFET families.

The XDP710 digital hot-swap controller meets HGX platform product requirements. Like its unique features, such as optional external fet selection using resistor strapping and boost mode, it helps that XDP710 comes in a small package, easy to design in, said Abhijit Datta, Sr power architect and subject matter expert at NVIDIA.

“The XDP710 hot-swap controller is a feature-rich device with high-precision analogue-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 the XDP710 controller is its advanced closed-loop SOA control and the fully digital operating mode. This leads to a lower bill-of-material (BOM), reducing the number of external components and design time, allowing faster time-to-market, claimed the company. The XDP XDP710 can also operate in analogue-assisted digital mode to support legacy systems.

The XDP XDP710 digital hot-swap and system monitoring controller IC is available in a 29-lead (6x6mm²) VQFN package.
