What are the key features of LM25069PMM-2?
- Single-channel hot swap control with adjustable power and current-limit thresholds for safe live-board insertion
- Low-voltage operation suitable for 3.3 V and 5 V positive supply rails in telecom and server backplane designs
- Compact 10-pin TSSOP-10 package with integrated gate drive for external N-channel MOSFET pass element
- Fault flag output and auto-retry capability simplify system-level fault management without external supervisory logic
What is LM25069PMM-2 used for?
LM25069PMM-2 is designed for telecom line cards, server blade modules, and industrial equipment that require hot-swappable board insertion without supply voltage glitches or in-rush current spikes. Its adjustable power-limit and current-sense threshold allow engineers to protect both the board and the backplane bus under fault conditions. The compact TSSOP-10 footprint suits dense PCB layouts in rackmount systems where board width is constrained.

Frequently Asked Questions
What supply voltage range does LM25069PMM-2 support for hot swap control on a server backplane?
LM25069PMM-2 is designed for positive low-voltage rails, typically covering 2.7 V to 16 V input range, making it appropriate for 3.3 V, 5 V, and 12 V server and telecom backplane designs. Its single control channel and adjustable thresholds allow the protection level to be tuned precisely for the target supply rail and load current.
How does the adjustable power-limit threshold in LM25069PMM-2 help protect a hot-plugged PCB during insertion?
The adjustable power-limit feature lets designers set a peak power ceiling via external resistors, so in-rush current during capacitor charge-up is constrained to safe levels. This prevents voltage droops on the shared backplane bus and protects the external pass MOSFET from exceeding its safe operating area. Threshold resistors allow the same LM25069PMM-2 IC to be reused across boards with different load profiles.
Is LM25069PMM-2 a good fit for a compact 10-slot ATCA shelf where board space near the edge connector is limited to under 5 mm width?
Yes. The 10-pin TSSOP-10 package measures approximately 3 mm × 4.4 mm, and the LM25069PMM-2 requires only a small external N-channel MOSFET, current-sense resistor, and a few passive components. This solution fits easily within a 5 mm edge-connector protection zone and handles the single-channel control needed for each blade's positive supply rail.
