TPS259573DSGR

Current Regulation/Management Overview

The TPS259573DSGR is a hot-swap voltage controller and electronic fuse from Texas Instruments, housed in an 8-WSON package. It supports input voltages from 2.7 V to 18 V and delivers up to 4 A of output current with an on-resistance of 34 mΩ. The device features fast overvoltage protection and operates within a junction temperature range of -40°C to +125°C.

Current Regulation/Management Feature Summary

• Integrates an electronic fuse for load protection against overcurrent and short circuits
• Provides fast overvoltage protection to safeguard downstream components
• Supports hot-swap insertion without causing system voltage droop

Current Regulation/Management Applications

• Server backplane power distribution
• Industrial control system inputs
• Communication equipment power interfaces

Current Regulation/Management Procurement Notes

Verify the specific suffix 'DSGR' corresponds to the tape-and-reel packaging configuration required for your assembly line. Confirm that the 8-WSON footprint matches your PCB design guidelines. Ensure the component meets RoHS compliance standards for your target market regulations before finalizing procurement orders.

Current Regulation/Management Selection Notes

Select this component when a single-channel solution is needed for high-current loads up to 4 A. It is suitable for systems requiring robust overvoltage protection and low on-resistance. Consider the thermal performance of the WSON package for your enclosure design. Verify input voltage ranges align with your system's power supply specifications.

Current Regulation/Management Part Context

This part belongs to the TPS2595x family of hot-swap controllers designed for reliable power management. It serves as a critical interface between the power source and the load, ensuring safe operation during connection and disconnection events. The device integrates multiple protection features into a compact form factor.

Current Regulation/Management Replacement Considerations

Check datasheets for alternative models within the TPS2595 series, such as TPS259570 or TPS259571, which may offer different resistance values or protection thresholds. Ensure pin compatibility and electrical parameters match your existing design requirements before substituting.
