STEF05WPUR

Current Regulation/Management Overview

The STEF05WPUR is an electronic fuse regulator designed for 5 V line protection, manufactured by STMicroelectronics. It features a continuous output current of 3.6 A and operates with an input voltage range of 3.1 V to 10 V. The device is housed in a 10-VFDFN package with exposed pad, measuring 3x3 mm. It supports surface mount installation and functions within a junction temperature range of -40°C to 125°C. This component integrates overcurrent protection capabilities suitable for robust circuit management.

Current Regulation/Management Feature Summary

• Integrates electronic fuse functionality for comprehensive circuit protection against overcurrent conditions
• Provides stable regulation for 5 V power lines with defined input voltage tolerance
• Utilizes compact surface-mount packaging for efficient board space utilization

Current Regulation/Management Applications

• Protection of 5 V distribution lines in electronic systems
• Overcurrent protection for sensitive downstream components
• Power management modules requiring integrated fuse regulation

Current Regulation/Management Procurement Notes

Verify the specific suffix 'W' against official STMicroelectronics documentation to confirm package or tape-and-reel variations. Ensure compatibility with 10-DFN footprint requirements. Confirm RoHS compliance status and moisture sensitivity level prior to assembly planning. Cross-reference datasheet revisions for any updates to electrical characteristics or thermal performance data.

Current Regulation/Management Selection Notes

Select this component when a dedicated electronic fuse solution is required for 5 V applications. Consider the 3.6 A current rating and 10 V maximum input voltage limits. Evaluate the 10-DFN package constraints for thermal dissipation and PCB layout. Compare against standard fuses if resettable protection is needed without external control logic.

Current Regulation/Management Part Context

This part belongs to the STEF05 family of electronic fuses from STMicroelectronics. These devices are categorized under Power Management ICs (PMIC) specifically for current regulation and management. The family focuses on providing integrated protection for low-voltage DC lines, replacing traditional discrete fuse components with active regulation capabilities.

Current Regulation/Management Replacement Considerations

Consult official substitution lists for direct equivalents. Verify pinout compatibility and electrical parameter alignment before replacing.
