TPS259541DSGR

Current Regulation/Management Overview

The TPS259541DSGR is a single-channel electronic fuse from Texas Instruments, designed for hot-swap applications. It operates within an input voltage range of 2.7V to 18V and supports output currents up to 4A. The device features a current limit accuracy of ±7.5% and functions in the -40°C to 125°C junction temperature range. Packaged in an 8-WSON (2x2) surface-mount format with an exposed thermal pad, it integrates protection mechanisms including power-fail detection.

Current Regulation/Management Feature Summary

• Integrates electronic fuse functionality with adjustable current limiting for load protection
• Supports hot-swap operations with controlled inrush current management
• Includes power-fail detection capability for system monitoring
• Features high-precision current limit accuracy for reliable circuit protection

Current Regulation/Management Applications

• Hot-swap voltage controller applications
• Power distribution systems requiring overcurrent protection
• Industrial equipment power management
• Telecommunications infrastructure power supplies

Current Regulation/Management Procurement Notes

Verify the complete part number including the DSGR suffix to ensure correct package type and tape-and-reel configuration. Confirm RoHS3 compliance status and moisture sensitivity level requirements for your assembly process. Check for any specific application notes or reference designs provided by Texas Instruments for optimal layout and component selection.

Current Regulation/Management Selection Notes

Select this component when a single-channel eFuse solution is required for 2.7V to 18V systems. Ensure the 4A maximum output current meets your load requirements. Consider the 8-WSON package size constraints and thermal dissipation needs due to the exposed pad design. Verify that the ±7.5% current limit precision aligns with your protection thresholds.

Current Regulation/Management Part Context

This device belongs to the TPS2595xx series of electronic fuses from Texas Instruments. It shares functional similarities with other members like the TPS259540 and TPS259571 but differs in specific current ratings and control features. The series is designed for robust power distribution in demanding environments.

Current Regulation/Management Replacement Considerations

The RS31311BR from Reed Semiconductor Corp. is listed as a similar alternative. Verify pin compatibility, current ratings, and voltage specifications before substitution.
