TPS259460LRPWR

Current Regulation/Management Overview

The TPS259460LRPWR is a Texas Instruments eFuse rated for 2.7 V to 23 V input and 5.5 A continuous current. It features a typical 28 mΩ on-resistance in a 10-pin HotRod QFN package. The device supports bidirectional current flow when enabled, making it suitable for USB OTG applications. Key protections include adjustable overvoltage lockout, programmable overcurrent limits via an external resistor, and thermal shutdown. Integrated back-to-back FETs ensure reverse current blocking when disabled.

Current Regulation/Management Feature Summary

• Bidirectional current support enables On-The-Go functionality with reverse current blocking when disabled
• Integrated back-to-back FETs provide compact power path management
• Programmable overcurrent threshold allows precise load protection tuning
• Adjustable output slew rate controls inrush current during startup

Current Regulation/Management Applications

• USB On-The-Go (OTG) port protection
• Hot-swap server blade power distribution
• Peripheral board power entry modules
• Industrial equipment input protection

Current Regulation/Management Procurement Notes

Verify the specific suffix LRPWR corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the component meets RoHS compliance standards applicable to your manufacturing region. Ensure the ordering quantity aligns with standard reel sizes to avoid cut-tape handling requirements. Cross-reference the manufacturer datasheet revision to confirm pinout compatibility with existing design files.

Current Regulation/Management Selection Notes

Select this component when bidirectional current capability is required within a hot-pluggable environment. The integrated back-to-back FET architecture eliminates the need for external diodes or complex control logic. Verify that the application voltage remains within the 2.7 V to 23 V operating range. Consider the thermal performance of the HotRod package if high ambient temperatures are expected.

Current Regulation/Management Part Context

This part belongs to the TPS25946xx family of electronic fuses designed for robust power distribution. It integrates protection features typically found in discrete solutions into a single small-footprint package. The series targets applications requiring reliable power path management with minimal external component count.

Current Regulation/Management Replacement Considerations

The TPS259461LRPWR serves as a functional substitute within the same family, sharing identical electrical characteristics and pinout configurations. Both devices utilize the same 10-pin HotRod QFN package and support bidirectional current flow. Verify that any replacement maintains the same thermal resistance specifications for adequate heat dissipation.
