Key Features
- Ultra-low 2.7 mΩ on-resistance handles 15 A continuous load current with minimal power dissipation
- ±1.5% accurate current monitor output enables precise system-level power budgeting without external shunt resistors
- Adjustable overvoltage, overcurrent, and fault management thresholds fit diverse 2.7 V to 24 V hot-swap system requirements
Applications
The TPS259822LNRGER is designed for server and telecom hot-swap power rail protection where high current and tight monitoring accuracy are required. Its 2.7 V to 24 V range covers 3.3 V, 5 V, 12 V, and 24 V distributed power architectures in data center blade servers and enterprise networking equipment. The adjustable fault management and low RDS(on) reduce thermal stress during hot insertion events, improving system reliability and mean time between failures.

Frequently Asked Questions
How does TPS259822LNRGER's 2.7 mΩ on-resistance benefit high-current 12 V server rail designs?
At 15 A load on a 12 V rail, the 2.7 mΩ FET dissipates only 0.6 W, keeping junction temperature rise minimal without a heatsink. This allows the TPS259822LNRGER to protect high-current server card slots while remaining within a 24-pin QFN thermal budget, reducing board area and cooling requirements.
What accuracy does TPS259822LNRGER's current monitor achieve and how is it used in power management firmware?
The TPS259822LNRGER provides a ±1.5% accurate current monitor output, enabling firmware to track load power consumption within tight bounds across the 2.7 V to 24 V input range. This precision eliminates the need for dedicated current sense amplifiers with external shunt resistors, reducing component count and simplifying board layout.
How does TPS259822LNRGER handle overvoltage protection on a 3.7 V overvoltage threshold system?
TPS259822LNRGER includes a fixed 3.7 V overvoltage protection threshold that disconnects the load within microseconds when input exceeds this level. Combined with adjustable overcurrent limits up to 15 A, it protects downstream logic circuits on 3.3 V rails from transient overvoltage events during hot-swap insertion in backplane systems.
For a 48 V to 12 V converted rail powering PCIe cards, when would TPS259822LNRGER be the right eFuse choice?
TPS259822LNRGER is appropriate when the post-regulation rail is 12 V or below with up to 15 A load per slot. Its 24 V maximum input covers 12 V bus with transient headroom, and the 2.7 mΩ RDS(on) keeps conduction loss below 2 W at full load, meeting PCIe hot-plug power integrity requirements.
