TPS259814LRPWR

Current Regulation/Management Overview

The TPS259814LRPWR is a single-channel hot-swap voltage controller manufactured by Texas Instruments. It operates within an input voltage range of 2.7 V to 16 V and supports a continuous load current of 10 A. The device integrates an N-channel power MOSFET with a typical on-resistance of 6 mΩ. It utilizes a VQFN-HR-10 package for surface-mount installation. The component functions as an electronic fuse, providing comprehensive protection against overcurrent, short circuits, and reverse polarity conditions while enabling controlled power-up sequencing.

Current Regulation/Management Feature Summary

• Integrates a low on-resistance internal switch to minimize conduction losses during normal operation.
• Provides precise current limiting and foldback protection to safeguard downstream circuitry from fault conditions.
• Supports controlled ramp-up of output voltage to manage inrush current during system initialization.

Current Regulation/Management Applications

• High-density server backplane power distribution
• Industrial equipment input power protection
• Telecommunications infrastructure power modules

Current Regulation/Management Procurement Notes

Verify the specific suffix LRPWR corresponds to the required tape and reel packaging configuration. Confirm that the thermal performance requirements align with the VQFN-HR-10 package capabilities under expected operating loads. Ensure compatibility with the target board layout regarding exposed pad thermal dissipation. Validate that the 16 V maximum input rating exceeds the system's peak supply voltage including transients.

Current Regulation/Management Selection Notes

Select this component when a 10 A current capacity is required within a 16 V input envelope. The 6 mΩ on-resistance offers a balance between efficiency and cost compared to higher current variants. Consider the VQFN-HR-10 footprint constraints during PCB design. Evaluate thermal management strategies given the power dissipation characteristics at full load currents.

Current Regulation/Management Part Context

This device belongs to the TPS25981 family of hot-swap controllers designed for robust power distribution applications. It shares architectural similarities with other members like the TPS259814ARPWR but differs in specific ordering suffixes related to packaging or regional compliance. The family targets applications requiring reliable power path management with integrated protection features.
