What is LM25056PSQ/NOPB used for?
The LM25056PSQ/NOPB is designed for system-level power management in servers, telecom line cards, and industrial controllers where accurate single-channel current and power monitoring enables efficiency optimisation and predictive maintenance. Its adjustable threshold inputs allow the system controller to configure overcurrent trip points without external resistor networks, reducing BOM complexity. The voltage supervisor output also drives power-good and reset logic, making it a compact single-IC solution for rail monitoring in multi-supply systems.

Frequently Asked Questions
What monitoring functions does LM25056PSQ/NOPB combine in a single IC for server power designs?
The LM25056PSQ/NOPB combines single-channel current measurement, voltage measurement, and power calculation with a voltage supervisor/reset output in one 24-pin QFN device. This replaces discrete shunt amplifiers, voltage dividers, and comparator circuits, saving approximately 5 to 10 passive components per monitored rail and reducing PCB area in rack-mount server power distribution boards.
How does the adjustable threshold feature of LM25056PSQ/NOPB help designers set overcurrent protection limits?
The adjustable threshold pins allow designers to set overcurrent and overvoltage trip levels using external resistor dividers without firmware intervention. For example, a 12 V / 10 A rail can have its overcurrent threshold set to 11 A by selecting a resistor pair with a ratio corresponding to the desired threshold voltage. This hardware-configurable approach ensures protection triggers within microseconds, faster than any software-polled ADC loop.
What is the significance of LM25056PSQ/NOPB's 15-year YTEOL for long-lifecycle infrastructure designs?
A 15-year YTEOL means Texas Instruments commits to manufacturing LM25056PSQ/NOPB for at least 15 years, ensuring spare-parts availability through the full operational life of telecommunications base stations, industrial PLCs, and data-centre infrastructure — equipment categories often requiring 10 to 15 year field service. This eliminates mid-lifecycle re-qualification costs that arise when a component is discontinued and replaced with a non-pin-compatible alternative.
How does LM25056PSQ/NOPB's QFN-24 package compare to a SOIC-8 shunt monitor in PCB integration?
The 24-pin rectangular QFN package measures approximately 4 mm × 4 mm, integrating current sensing, voltage monitoring, and supervisor functions that would otherwise require a SOIC-8 current-sense amplifier plus a separate SOIC-8 voltage supervisor — together occupying roughly 60 mm² of PCB area. The QFN-24 consolidates these into approximately 16 mm², a 4-fold space saving, while adding power calculation and adjustable threshold capability not present in discrete SOIC-8 solutions.
