TPS259480AYWPR

Current Regulation/Management Overview

The TPS259480AYWPR is a high-side electronic fuse (eFuse) regulator manufactured by Texas Instruments. It operates within an input voltage range of 3.5 V to 23 V, with a 28-V absolute maximum rating. The device integrates back-to-back FETs and supports bidirectional power delivery. Key electrical parameters include an on-resistance of 12.2 mΩ and a current limit capability up to 8 A. It functions in a DSBGA-12 package (2.43x1.74 mm) and can be powered from either the IN or OUT pin.

Current Regulation/Management Feature Summary

• Supports bidirectional power delivery for flexible system design
• Integrates back-to-back FETs to eliminate external components
• Enables hot-swap operations with wide operating input voltage range
• Allows powering from either the input or output pin

Current Regulation/Management Applications

• Hot-swap voltage control in industrial systems
• Power distribution units requiring bidirectional flow
• High-side protection for load switches

Current Regulation/Management Procurement Notes

Verify the specific suffix 'YWPR' corresponds to the required tape-and-reel packaging configuration. Confirm that the 12.2-mΩ on-resistance meets thermal requirements for your 8-A application. Ensure compatibility with the 3.5-V to 23-V operating range. Check for RoHS compliance status as indicated in official documentation.

Current Regulation/Management Selection Notes

Select this component when bidirectional power flow is required alongside high-side protection. The integrated back-to-back FETs simplify board space compared to discrete solutions. Verify that the 12.2-mΩ resistance provides acceptable conduction losses at 8 A. Ensure the 3.5-V minimum start-up voltage aligns with your system's power rails.

Current Regulation/Management Part Context

This part belongs to the TPS25948 family of eFuses designed for robust power management. It serves as a replacement for traditional fuses and circuit breakers in modern electronics. The device offers superior protection features including overcurrent, short-circuit, and reverse polarity protection within a compact footprint.

Current Regulation/Management Replacement Considerations

Check for direct substitutes within the TPS25948 series, such as TPS259481 or TPS259482, which may offer different current ratings or resistance values. Ensure pinout compatibility before substitution.
