Frequently Asked Questions
What is the primary function of the LM25056APSQE/NOPB?
The LM25056APSQE/NOPB combines hot-swap power control with system power measurement in a single IC. It monitors and controls the inrush current during board insertion in live backplanes (hot-swap function) while simultaneously measuring supply voltage, load current, and power consumption via a PMBus digital interface, providing complete power telemetry for system management systems.
What is the adjustable reset threshold voltage of the LM25056APSQE/NOPB?
The LM25056APSQE/NOPB has an adjustable undervoltage lockout (UVLO) threshold with a reset voltage of 2.4V, which can be programmed using external resistors. This allows the designer to set the minimum operating voltage at which the hot-swap control circuit activates, preventing power-on of downstream loads until the supply rail has stabilized above the set threshold.
What communication interface does the LM25056APSQE/NOPB use for power data reporting?
The LM25056APSQE/NOPB uses the PMBus (Power Management Bus) protocol, a two-wire serial interface based on SMBus, for digital communication of power measurement data. Through PMBus commands, host systems can read back real-time voltage, current, and power readings, configure operating parameters, and read fault status registers, enabling comprehensive power monitoring in managed server and telecom infrastructure.
What package is the LM25056APSQE/NOPB available in?
The LM25056APSQE/NOPB is packaged in a 24-pin QFN (Quad Flat No-Lead) package, JESD-30 code R-XQCC-N24. The no-lead package provides a compact, thermally efficient footprint suitable for high-density power management PCBs in server blades and telecom equipment, and its exposed thermal pad facilitates effective heat dissipation to the PCB ground plane during high-current hot-swap operations.
