NIV6350MT1TXG

Current Regulation/Management Overview

The NIV6350MT1TXG is a high-performance electronic fuse (eFuse) manufactured by onsemi, designed for robust circuit protection in demanding applications. It operates with a maximum input voltage of 24V and supports an output current of 3A. The device features a low on-resistance to minimize power loss and heat generation during normal operation. It integrates comprehensive protection mechanisms including overcurrent, thermal shutdown, reverse current blocking, and overvoltage clamping. The component is housed in a compact 10-WDFNW (3x3) package with exposed pad, suitable for surface mount assembly. It meets AEC-Q100 automotive qualification standards and operates within a temperature range of -40°C to 125°C.

Current Regulation/Management Feature Summary

• Integrates overvoltage clamping circuitry to protect downstream loads from transient voltage spikes without shutting down the system.
• Provides adjustable output current limit protection and thermal shutdown to prevent damage during fault conditions.
• Includes digital enable control and FLAG pin for status monitoring and fault identification.
• Features integrated current monitoring via IMON pin for real-time current sensing.

Current Regulation/Management Applications

• Automotive infotainment and body electronics power distribution
• Industrial equipment power management systems
• USB hub and peripheral port protection
• Server and telecom infrastructure power rails

Current Regulation/Management Procurement Notes

Verify the specific suffix MT1 indicates the latch-off mode variant when ordering. Confirm that the 10-WDFNW package dimensions match your PCB footprint requirements. Ensure compatibility with your system's logic levels for the EN and FLAG pins. Check for any recent product change notices or end-of-life announcements from onsemi regarding this specific part number before finalizing procurement plans.

Current Regulation/Management Selection Notes

Select the NIV6350MT1TXG when a 24V input rating and 3A continuous current capability are required. Choose the MT1 suffix if latch-off behavior after a fault event is preferred over automatic retry. Consider the integrated overvoltage clamping feature if protecting sensitive loads from input transients is critical. Evaluate the 10-WDFNW package size against available board space constraints.

Current Regulation/Management Part Context

The NIV6350 series belongs to onsemi's family of high-side electronic fuses designed for automotive and industrial applications. It serves as a solid-state replacement for traditional fuses and relay-based protection circuits. The device offers superior reliability and diagnostic capabilities compared to passive components. It is part of a broader portfolio that includes variants with different current ratings and package options.

Current Regulation/Management Replacement Considerations

NIV6350MT2TXG is a manufacturer-recommended alternative offering auto-retry functionality instead of latch-off.

Current Regulation/Management FAQ

What is the difference between the MT1 and MT2 suffixes?

The MT1 suffix denotes a latch-off mode where the device remains off after a fault until power is cycled or the EN pin is toggled. The MT2 suffix indicates an auto-retry mode where the device attempts to recover automatically once the fault condition clears and temperature drops below the threshold.

Does the NIV6350 provide reverse current protection?

Yes, the NIV6350 integrates reverse current protection to prevent backflow from the load side to the source, which is critical for maintaining system stability during power failures or specific load characteristics.
