TPS259470LRPWR

Current Regulation/Management Overview

The TPS259470LRPWR is a single-channel hot-swap voltage controller from Texas Instruments, functioning as an electronic fuse. It operates within a supply voltage range of 2.7 V to 23 V and supports load currents up to 5.5 A with a typical on-resistance of 28 mΩ. The device features adjustable current limiting between 500 mA and 6 A, low quiescent current of 445 µA, and power-fail detection. It is housed in a VQFN-HR-10 package and rated for operation from -40°C to +125°C.

Current Regulation/Management Feature Summary

• Integrated eFuse architecture providing overcurrent protection and controlled inrush current management
• Adjustable current limit capability allowing precise load protection settings
• Power-fail detection feature for monitoring input supply integrity
• Low standby current consumption suitable for battery-backed or always-on systems

Current Regulation/Management Applications

• Hot-swap insertion in server backplanes
• Protection for peripheral cards in industrial equipment
• Input power distribution in telecom infrastructure
• Evaluation using the TPS25947EVM development module

Current Regulation/Management Procurement Notes

Verify the complete part number including suffixes against official Texas Instruments documentation to ensure correct package and temperature grade. Confirm RoHS compliance status through the manufacturer's datasheet. Check for moisture sensitivity levels if storage conditions are critical. Ensure ordering quantities align with reel specifications rather than assuming cut-tape availability for all volumes.

Current Regulation/Management Selection Notes

Select this component when designing circuits requiring robust hot-swap capabilities with high current handling. The 28 mΩ on-resistance minimizes conduction losses compared to discrete solutions. Consider the VQFN-HR-10 package for space-constrained PCB layouts. Validate that the required current limit falls within the 500 mA to 6 A adjustable range specified for the series.

Current Regulation/Management Part Context

This device belongs to the TPS25947 family of hot-swap controllers. It shares functional similarities with variants like TPS259474LRPWR and TPS259472ARPWR, which offer different pin configurations or electrical characteristics within the same series. The family is designed for PMIC applications requiring integrated power path control.

Current Regulation/Management Replacement Considerations

Direct substitutes include TPS259474LRPWR and TPS259472ARPWR from the same Texas Instruments series. Verify pin compatibility and specific electrical parameter differences before substitution.
