TPS259481AYWPR

Current Regulation/Management Overview

The TPS259481AYWPR is a high-side electronic fuse (eFuse) power switch IC manufactured by Texas Instruments. It operates within an input voltage range of 3.5V to 23V, with an absolute maximum rating of 28V. The device integrates back-to-back FETs and supports bidirectional power delivery. It features a typical on-resistance of 12.2 mΩ and handles a continuous current of 8A. The component is housed in a DSBGA-12 package (2.43x1.74 mm) and is designed for surface-mount installation.

Current Regulation/Management Feature Summary

• Supports bidirectional power delivery allowing power flow from either IN or OUT terminals
• Integrates back-to-back field-effect transistors for compact high-side switching
• Wide operating input voltage range suitable for various power distribution applications

Current Regulation/Management Applications

• Power distribution systems requiring hot-swappable connections
• Bidirectional power delivery interfaces
• High-side load protection circuits

Current Regulation/Management Procurement Notes

Verify the specific suffix 'YWPR' corresponds to the required tape-and-reel packaging configuration. Confirm that the 12.43x1.74mm DSBGA footprint matches your PCB layout constraints. Ensure the 8A current rating and 12.2mΩ RDS(on) meet your thermal and efficiency requirements. Cross-reference the datasheet revision date to ensure compatibility with your design specifications.

Current Regulation/Management Selection Notes

Select this component when bidirectional power flow is required, as many standard eFuses are unidirectional. The wide 3.5V to 23V input range accommodates various bus voltages. Consider the small DSBGA-12 package if board space is limited. Verify that the 8A continuous current capability aligns with the load profile and that the thermal management strategy supports the power dissipation at the selected current level.

Current Regulation/Management Part Context

This part belongs to the TPS25948xx family of eFuses from Texas Instruments. These devices are designed for robust power distribution, offering integrated protection features such as overcurrent and short-circuit protection. The family typically includes variants with different current ratings and resistance values, sharing common interface and protection functionalities.

Current Regulation/Management Replacement Considerations

Check for other members of the TPS25948xx series with similar current ratings but different RDS(on) values. Verify pinout compatibility with existing designs before substituting. Ensure any alternative device also supports bidirectional power delivery if that feature is critical to the application.
