NIS3071MTW3TWG

Overview

The NIS3071MTW3TWG is a four-channel electronic fuse (eFuse) from onsemi, designed for high-side power distribution. It supports input voltages from 8V to 60V and provides independent overcurrent protection for each channel with a continuous current rating of 2.5A. The device integrates internal soft-start delay, adjustable current limiting, and thermal shutdown with auto-retry. Packaged in a 16-WQFN (5x6mm) footprint, it features high-level enable pins and a common open-drain fault pin for microcontroller interface.

Feature Summary

• Four independent channels providing individual load protection against short circuits and overloads
• Integrated thermal management with automatic retry functionality upon fault clearance
• Adjustable current limit and turn-on time control via external passive components
• High-level digital enable inputs allow flexible per-channel switching control

Applications

• Automotive body control modules
• Power distribution boxes
• Automotive area controllers
• General high-side load switches

Procurement Notes

Verify the specific suffix 'MTW3TWG' against the manufacturer's latest datasheet to confirm package type and tape/reel specifications. Ensure compatibility with your PCB footprint, as the device utilizes a 16-WQFN package. Confirm that the standard industrial grade meets your operational temperature requirements, distinct from the automotive-grade NIV prefix variants.

Selection Notes

Select this component when designing systems requiring multi-channel protection within a compact form factor. It is suitable for applications needing independent control of up to four loads without external current sensing resistors. Consider the adjustable parameters for optimizing surge current handling and protection thresholds relative to the connected load characteristics.

Part Context

This part belongs to the NIx3071 family of four-channel eFuses. While the NIV3071 variant is AEC-Q100 qualified for automotive use, the NIS3071 serves as the industrial-grade counterpart. Both share identical pinouts and functional specifications, allowing for design flexibility across different market segments while maintaining consistent protection logic.

Replacement Considerations

The NIV3071MTW3TWG is a direct pin-compatible alternative offering automotive qualification. Other single or dual-channel eFuses may require circuit redesign due to differing pin counts and control interfaces.
