TPS259531DSGR

Current Regulation/Management Overview

The TPS259531DSGR is a single-channel hot-swap voltage controller from Texas Instruments, functioning as an electronic fuse. It supports input voltages from 2.7 V to 18 V and delivers up to 4 A of current with a typical on-resistance of 34 mΩ. The device integrates fast overvoltage protection and power-fail detection. Operating within a temperature range of -40°C to +125°C, it is housed in an 8-pin WSON package.

Current Regulation/Management Feature Summary

• Integrates fast overvoltage protection for robust circuit safeguarding
• Includes power-fail detection capabilities for system monitoring
• Features low on-resistance for efficient power delivery

Current Regulation/Management Applications

• Hot-swap applications requiring controlled power insertion
• Systems needing precise current limiting and fault protection
• Industrial equipment requiring wide operating temperature ranges

Current Regulation/Management Procurement Notes

Verify the specific suffix 'DSGR' corresponds to the required tape-and-reel packaging configuration. Confirm that the marking code 'ES31' aligns with your manufacturing traceability requirements. Ensure compatibility with the 8-pin WSON footprint during PCB layout verification. Cross-reference the datasheet revision to confirm feature consistency.

Current Regulation/Management Selection Notes

Select this component when a single-channel solution with integrated eFuse functionality is required. It is suitable for designs needing protection against overvoltage and short circuits without external discrete components. Consider the 34 mΩ on-resistance for thermal management calculations. Verify that the 4 A current limit meets the load requirements of the target application.

Current Regulation/Management Part Context

This part belongs to the TPS2595xx family of hot-swap controllers. It shares architectural similarities with variants like the TPS259530DSGR and TPS259571DSGT, which offer comparable voltage and current specifications. The family is designed for PMIC applications requiring compact footprints and high reliability in power distribution networks.

Current Regulation/Management Replacement Considerations

Direct substitutes within the same family include TPS259530DSGR and TPS259571DSGT. These parts share identical pinouts and core functionalities but may differ in specific internal thresholds or marking codes. Verify electrical parameter equivalence before substitution.
