TPS259541DSGT

Current Regulation/Management Overview

The TPS259541DSGT is a single-channel electronic fuse (eFuse) from the Texas Instruments TPS2595xx family, housed in an 8-WSON package. It operates within an input voltage range of 2.7 V to 18 V and supports a continuous output current of 4 A with a typical on-resistance of 34 mΩ. The device features fast overvoltage protection and includes an integrated N-channel MOSFET. It is designed for hot-swap applications, offering precise current limiting and thermal shutdown capabilities.

Current Regulation/Management Feature Summary

• Integrates a low on-resistance N-channel MOSFET for efficient power delivery
• Provides fast overvoltage protection to safeguard downstream loads
• Supports hot-swap operations with controlled turn-on slew rates

Current Regulation/Management Applications

• Hot-swap connectors in industrial equipment
• Power distribution units in server backplanes
• Protection circuits for peripheral interfaces

Current Regulation/Management Procurement Notes

Verify the specific suffix 'DSGT' against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications. Ensure compatibility with standard surface-mount assembly processes by checking the recommended soldering profile. Confirm that the component meets all required environmental certifications for the target application before finalizing procurement orders.

Current Regulation/Management Selection Notes

Select this component when a compact solution is required for 4-A load protection within an 18-V system. The 8-WSON package offers a small footprint suitable for space-constrained designs. Consider the 34-mΩ on-resistance for minimizing conduction losses compared to higher resistance alternatives in similar voltage ranges.

Current Regulation/Management Part Context

This part belongs to the TPS2595xx series of eFuses, which are designed to replace traditional fuses and discrete MOSFET solutions. The series provides integrated protection features including overcurrent, overvoltage, and thermal management. The TPS259541 variant specifically targets high-current applications requiring robust fault protection in a minimal outline package.
