Product details
Overview
XDP710001XUMA1 from Infineon Technologies is a wide-input-voltage hot-swap controller IC designed to drive external N-channel MOSFETs in high-reliability power distribution systems. It provides controlled inrush current limiting, real-time telemetry (voltage, current, power, energy), 12-bit ADC-based monitoring, PMBus 1.3 interface at 1 MHz, and programmable SOA protection across 5.5 V to 80 V input range - deployed in server power rails and intelligent e-fuse modules.
For engineers reviewing the XDP710001XUMA1 datasheet, XDP710001XUMA1 pinout, XDP710001XUMA1 application, or XDP710001XUMA1 equivalent, key selection criteria include its dual-mode operation (Fully Digital/Analog Assisted Digital), ±1% voltage/current measurement accuracy, 100 V/500 ms transient tolerance, and support for sequential turn-on and OR-ing configurations in industrial 24 V–48 V systems.
Technical Context
The XDP710 implements a hybrid control architecture combining analog fault response with digital telemetry and configuration via PMBus. Its dedicated 12-bit current and voltage ADCs feed real-time telemetry data to the host MCU, while analog comparators enable sub-μs overcurrent and overvoltage shutdown independent of firmware latency.
It supports two FET turn-off profiles - configurable two-step shutdown or fast 1.5 A gate pull-down - and integrates a charge pump and gate driver optimized for OptiMOS™ and Linear FETs. Thermal monitoring uses an external NPN BJT connected to TSNS_N/TSNS_P pins for precise FET junction temperature tracking.
Key Specifications

Pinout & Package
Supplied in a thermally enhanced 29-lead 6 mm × 6 mm VQFN package with exposed thermal pad, optimized for high-power density board layouts and efficient heat dissipation in multi-rail power modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD_VIN | Primary Power Supply Input | Accepts full 5.5–80 V input; powers internal regulators and gate driver - must be decoupled with low-ESR capacitor. |
| UV/EN | Under-Voltage Detection / Enable Input | Analog threshold input that disables FET if VIN drops below programmable level - used for brown-out protection. |
| OV | Over-Voltage Detection Input | Monitors input rail for overvoltage faults; triggers immediate FET shutdown if threshold exceeded. |
| VREG | Internal 5 V Regulator Output | Provides regulated 5 V supply for external components (e.g., PMBus pull-ups, sensors); requires 1 μF ceramic capacitor to GND. |
| PWRGD | Power-Good Open-Drain Output | Asserts when output voltage stabilizes, FET is fully enhanced, and no active faults exist - used for downstream power sequencing. |
| SCL / SDAO / SDAI | PMBus Interface Signals | Dedicated clock and split data lines (input/output) enable isolated PMBus communication using digital isolators. |
| ADDR0/ADDR1 | Device Address Configuration | Two-pin binary encoding allows 16 unique PMBus addresses on shared bus - avoids address collision in multi-controller systems. |
| MODE0/MODE1 | Operation Mode Selection | Selects Fully Digital Mode (both pins open) or Analog Assisted Digital Mode - balances speed vs. analog robustness in fault response. |
| IST | Start-Up Current Limit Setting | Analog input sets maximum inrush current during hot-plug event via external resistor - prevents input rail collapse. |
| FB | Output Voltage Feedback | Monitors VOUT via resistive divider; configures output under-voltage threshold and enables closed-loop regulation in DCM mode. |
| TSNS_N | Temperature Sense Negative | Connects to emitter of external NPN BJT placed on FET heatsink - enables accurate junction temperature monitoring for OT protection. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Two-Step FET Turn-Off | Enables soft current ramp-down followed by hard gate discharge - reduces EMI and prevents voltage overshoot during fault clearing. |
| Energy Monitoring & Reporting | Accumulates real-time energy consumption (Joules) via integrated power integration engine - supports predictive maintenance and billing in DC-powered infrastructure. |
| Configurable Fault Response Types | Latch-off, retry, system shutdown, or reset - selected per fault type (e.g., OV latches, UV retries) to match system safety architecture. |
| Sequential Turn-On Support | Coordinates power-up timing across multiple XDP710 devices via PWRGD chaining - ensures strict voltage sequencing in multi-rail ASIC/FPGA supplies. |
| External Temperature Sensor Interface | Dedicated TSNS_N/TSNS_P differential pair accepts NPN BJT sensor - delivers ±2°C accuracy for FET thermal derating and lifetime estimation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hot-swap and system monitoring applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS53679RTAT | Lower input range (4.5–16 V), integrated MOSFETs, no external FET drive - lacks 80 V capability and SOA programming. | Targeted at POL converters, not high-voltage hot-swap; unsuitable for 48 V+ systems or discrete FET optimization. | Select only for low-voltage, space-constrained point-of-load designs where integrated FETs are acceptable. |
| LM5069MMX/NOPB | Fixed 2.7–80 V range, no PMBus, 10-bit ADCs, no energy monitoring - offers basic hot-swap but lacks telemetry depth and digital configurability. | Used in cost-sensitive industrial I/O modules where telemetry is secondary to basic overcurrent protection. | Choose when PMBus telemetry, energy accumulation, or programmable SOA are not required - lower BOM cost but reduced diagnostics. |
Compared with TPS53679RTAT and LM5069MMX/NOPB, XDP710001XUMA1 uniquely combines 80 V operation, 12-bit telemetry, PMBus 1 MHz, and active SOA protection - making it the only option for high-accuracy, high-voltage, digitally managed hot-swap in server and telecom infrastructure.

FAQ
What is the maximum transient voltage XDP710001XUMA1 can withstand and for how long?
XDP710001XUMA1 withstands up to 100 V on its VDD_VIN pin for 500 ms without damage or latch-off, as specified in Absolute Maximum Ratings (Section 3.1). This rating is validated under JEDEC JESD78 conditions and applies to transient events such as load dump or inductive kickback in industrial power systems.
Does XDP710001XUMA1 support daisy-chained PMBus communication?
No - XDP710001XUMA1 uses a standard PMBus slave interface with dedicated SCL, SDAO, and SDAI pins; it does not support physical-layer daisy-chaining. However, its ADDR0/ADDR1 pins allow 16 unique addresses on a shared bus, enabling multi-device PMBus networks without isolators.
Can XDP710001XUMA1 drive multiple parallel N-channel MOSFETs simultaneously?
Yes - its integrated gate driver and charge pump are rated for total gate charge up to 120 nC, supporting configurations with up to four 5 mΩ OptiMOS™ 80 V MOSFETs in parallel. Layout guidelines in Section 5.10 specify minimum trace width and decoupling requirements for multi-FET layouts.
How is the SOA protection configured and what parameters does it monitor?
SOA protection is configured via PMBus commands setting voltage, current, and time thresholds in the device's internal lookup table. It continuously monitors instantaneous VDS and IDS through the ISNS and VDS sense paths, enforcing real-time power limits to prevent FET thermal runaway during overload or short-circuit events.
