NIS3071MTW6TWG

Overview

The NIS3071MT4TWG is a four-channel electronic fuse (eFuse) power distribution IC manufactured by onsemi. It supports input voltages from 8 V to 60 V and provides independent high-side switching for each channel with a maximum continuous current of 2.5 A per output. The device integrates adjustable current limiting, programmable soft-start timing, and thermal protection. Key electrical specifications include a maximum on-resistance of 92 mΩ and an operating temperature range from -40°C to +150°C. It utilizes a WQFN-16 surface-mount package.

Feature Summary

• Four independent high-side channels with individual enable control
• Integrated overcurrent, short-circuit, and thermal protection without external shunts
• Programmable current limit and soft-start delay via external components
• Common open-drain fault status reporting pin

Applications

• Automotive body control modules
• Vehicle power distribution boxes
• General-purpose load switching in industrial equipment
• Protection circuits for automotive lighting and motors

Procurement Notes

Verify the exact suffix against official documentation, as the provided model contains a potential typographical variance compared to standard listings like NIS3071MT4TWG. Confirm RoHS compliance and lead times directly with authorized distributors or the manufacturer. Ensure the ordering part number matches the specific package and tape-and-reel requirements for your production line.

Selection Notes

Select this component when designing systems requiring multi-channel load protection with adjustable parameters. It is suitable for applications needing independent channel control and integrated safety features without external current sensing resistors. Consider the thermal resistance requirements if driving full load currents, as junction temperature management is critical for sustained 2.5 A operation.

Part Context

This device belongs to the NIS3071 series of eFuses designed for robust power distribution. It serves as a solid-state alternative to traditional fuses and mechanical relays. The series offers configurable protection thresholds and timing, making it adaptable for various voltage levels within the specified 8 V to 60 V range across multiple industry sectors.

Replacement Considerations

The NIV3071 is a confirmed automotive-grade variant within the same family. It shares identical pinouts and functional characteristics but meets AEC-Q100 standards and PPAP requirements. Designers can often substitute between these parts if qualification levels differ, provided the environmental ratings align with the application.
