Hot-swap controller protects AI servers
The XDP711-001 48-V digital hot-swap controller from Infineon offers programmable SOA current control for high-power AI servers. It provides I/O voltage monitoring with an accuracy of ≤0.4% and system input current monitoring with an accuracy of ≤0.75% across the full ADC range, enhancing fault detection and reporting.
Built on a three-block architecture, the XDP711-001 integrates high-precision telemetry, digital SOA control, and high-current gate drivers capable of driving up to eight N-channel power MOSFETs. It is designed to drive multiple MOSFETs in parallel, supporting the development of power delivery boards for 4-kW, 6-kW, and 8-kW applications.
The controller operates within an input voltage range of 7 V to 80 V and can withstand transients up to 100 V for 500 ms. It provides input power monitoring with reporting accuracy of ≤1.15% and features a high-speed PMBus interface for active monitoring.
Programmable gate shutdown for severe overcurrent protection ensures shutdown within 1 µs. With options for external FET selection, one-time programming, and customizable fault detection, warning programming, and de-glitch timers, the XDP711-001 offers flexibility for various use cases. Additionally, its analog-assisted digital mode maintains backward compatibility with legacy analog hot swap controllers.
The XDP711-001 will be available for order in mid-2025. For more information on the XPD series of protection and monitoring ICs, click here.
