NIS5452MT1TXG

Current Regulation/Management Overview

The NIS5452MT1TXG is a high-side electronic fuse regulator manufactured by onsemi. It integrates overcurrent protection and load management in a compact WDFN-10 package measuring 3x3 mm with a height of 0.8 mm. The device operates within a voltage range up to 5.85 V and supports a continuous output current of 1 A. It features a maximum input voltage rating of 10 V and functions reliably across an operating temperature range from -40°C to +125°C.

Current Regulation/Management Feature Summary

• Integrates high-side electronic fuse functionality for precise overcurrent protection
• Provides compact surface-mount solution in a low-profile WDFN-10 package
• Supports load management capabilities for connected peripheral devices

Current Regulation/Management Applications

• Protection of USB ports and data lines
• Guarding GPIO interfaces against short circuits
• Overcurrent protection for audio line drivers

Current Regulation/Management Procurement Notes

Verify the specific suffix MT1TXG to ensure correct packaging and tape-and-reel configuration. Confirm RoHS compliance status through official datasheets as regulatory requirements vary by region. Check for obsolescence notices, as this component may be subject to lifecycle changes or replacement recommendations from the manufacturer.

Current Regulation/Management Selection Notes

Select this component when designing circuits requiring integrated high-side switching and fault protection in space-constrained layouts. Ensure the system voltage does not exceed the 10 V absolute maximum rating. Consider the thermal performance of the WDFN-10 package for applications with sustained load currents near the 1 A limit.

Current Regulation/Management Part Context

This part belongs to the NIS54xx series of electronic fuses designed for portable electronics. It replaces traditional discrete fuse and switch combinations, reducing board space and assembly complexity. The series is optimized for consumer devices where reliable power distribution and fault isolation are critical for user safety and device longevity.

Current Regulation/Management Replacement Considerations

The manufacturer advises contacting sales for equivalent models due to potential obsolescence. Verify pin compatibility and electrical ratings before substituting with other WDFN-10 electronic fuses.
