TPS25210LRPWR

Current Regulation/Management Overview

The TPS25210LRPWR is a high-side electronic fuse (eFuse) voltage controller from Texas Instruments, designed for robust power distribution. It operates within an input voltage range of 2.7 V to 5.7 V and supports a continuous current of 4 A. The device features a low on-resistance of 31 mΩ and integrates back-to-back FETs for reverse polarity protection. It withstands absolute maximum voltages up to 28 V and negative voltages down to –15 V. Packaged in a 10-VQFN-HR (2x2) format, it provides compact integration for system protection.

Current Regulation/Management Feature Summary

• Integrates back-to-back FETs to provide inherent reverse polarity protection without external components.
• Offers wide operating input voltage range suitable for various standard bus architectures.
• Withstands negative voltage transients up to –15 V for enhanced fault tolerance.

Current Regulation/Management Applications

• Hot-swap voltage control in server and storage systems
• Power distribution units requiring integrated eFuse functionality
• Industrial equipment input protection circuits

Current Regulation/Management Procurement Notes

Verify the complete part number including the suffix 'LRPWR' to ensure correct package type and tape-and-reel configuration. Confirm that the required operating temperature range aligns with the industrial specifications listed in the official datasheet. Cross-reference the manufacturer's ordering information to validate availability and lead times through authorized channels.

Current Regulation/Management Selection Notes

Select this component when a compact solution for 4-A load protection is required within a 2.7-V to 5.7-V supply range. The integrated back-to-back FETs simplify design by eliminating external diodes for reverse polarity protection. Ensure the PCB layout accommodates the 2x2 mm QFN package thermal requirements for optimal performance under full load conditions.

Current Regulation/Management Part Context

This device belongs to the TPS2521xx family of electronic fuses, which are engineered for high-density power management applications. The series emphasizes small footprint and integrated protection features to reduce bill-of-materials count. The TPS25210 variant specifically targets applications needing reliable hot-swap capabilities and robust fault handling in space-constrained environments.

Current Regulation/Management Replacement Considerations

Consult the Texas Instruments product transition matrix for verified cross-references. Ensure any substitute maintains the 4-A current rating and 31-mΩ on-resistance characteristics. Verify compatibility with the 10-VQFN-HR package if board space is constrained.
