TPS259571DSGT

Current Regulation/Management Overview

The TPS259571DSGT is a single-channel hot-swap voltage controller and electronic fuse (eFuse) manufactured by Texas Instruments. It operates within an input voltage range of 2.7 V to 18 V and supports load currents from 0.5 A to 4 A. The device features a typical on-resistance of 34 mΩ and is housed in an 8-WSON package with dimensions of 2x2 mm. It functions across a junction temperature range of -40°C to +125°C, providing precise current limiting and power management capabilities for high-reliability applications.

Current Regulation/Management Feature Summary

• Integrates adjustable current limit functionality supporting loads up to 4 A
• Provides comprehensive protection against overcurrent, thermal overload, and reverse current conditions
• Features low on-resistance to minimize conduction losses during operation
• Includes integrated power monitoring and fault detection mechanisms

Current Regulation/Management Applications

• Hot-swap insertion protection for backplane and midplane systems
• Load switching and distribution in industrial equipment
• Power management for peripheral cards and expansion modules
• Overcurrent protection in server and networking infrastructure

Current Regulation/Management Procurement Notes

Verify the complete part number including the suffix to ensure correct packaging configuration. Confirm that the specific variant matches the required operational voltage and current specifications for the target application. Check for any recent product change notifications regarding assembly sites or material composition updates before finalizing procurement orders.

Current Regulation/Management Selection Notes

Select this component when designing circuits requiring robust hot-swap capabilities and precise current regulation. Ensure the external components align with the device's control requirements. Evaluate the thermal performance within the specified operating temperature range to maintain reliability under continuous load conditions.

Current Regulation/Management Part Context

This device belongs to the TPS2595 series of hot-swap controllers. It shares functional similarities with other members like the TPS259570 but differs in specific electrical characteristics and pin configurations. The series is designed for high-performance power distribution where system availability and component protection are critical priorities.

Current Regulation/Management Replacement Considerations

The TPS259571DSGR is a direct alternative differing only in packaging format. Verify compatibility with existing footprints and reflow profiles when substituting between tape-and-reel and cut-tape variants.
