NIV6150MT2TXG

Current Regulation/Management Overview

The NIV6150MT2TXG is a single-channel electronic fuse IC designed for 5V power distribution. It features a maximum on-resistance of 20 mΩ and supports an output current limit of 1.2 A. The device operates within a supply voltage range of 5 V and withstands junction temperatures from -40°C to +125°C, with a power dissipation rating of 1.3 W. Packaged in a compact 10-WDFNW (3x3 mm) surface-mount format, it includes integrated overvoltage clamping, reverse current protection, and thermal shutdown. This component is AEC-Q100 qualified for automotive applications.

Current Regulation/Management Feature Summary

• Integrates an overvoltage clamp circuit that limits transient output voltages without shutting down the device, allowing continued load operation during voltage spikes.
• Provides adjustable output current limiting and automatic retry functionality upon thermal recovery, eliminating the need for manual reset after fault conditions.
• Includes digital enable control and a FLAG pin for status monitoring, alongside an IMON pin for proportional current sensing via external resistance.

Current Regulation/Management Applications

• USB port power distribution and protection
• Automotive infotainment system power rails
• Industrial I/O interface protection

Current Regulation/Management Procurement Notes

Verify the specific suffix MT2TXG to confirm the automatic retry behavior, as other variants may offer latch-off modes. Ensure the ordering quantity aligns with the manufacturer's standard reel size of 3000 units or cut tape availability. Confirm RoHS compliance and AEC-Q100 qualification requirements match the target application standards before finalizing procurement.

Current Regulation/Management Selection Notes

Select this component when a low-profile solution is required for 5V systems needing robust transient protection. The automatic retry feature suits applications where service interruptions must be minimized. Consider the 20 mΩ on-resistance for efficiency calculations and verify that the 1.2 A current limit meets the downstream load requirements without unnecessary tripping.

Current Regulation/Management Part Context

This part belongs to the NIS6150/NIV6150 family of resettable electronic fuses. The NIV6150 series serves as the industrial-grade counterpart to the automotive-qualified NIS6150 series. Both share similar functional architectures but differ in qualification standards and specific operating parameters defined by their respective industry certifications.

Current Regulation/Management Replacement Considerations

The NIV6150MT1TXG is a discontinued variant offering latch-off behavior instead of auto-retry. Designers transitioning from MT1 to MT2 must account for the change in fault recovery mechanism. No direct cross-manufacturer substitutes are documented in the provided data.

Current Regulation/Management FAQ

How does the NIV6150MT2TXG handle overvoltage events?

It utilizes an integrated overvoltage clamp circuit that restricts the output voltage during transients. Unlike standard eFuses, it does not shut down the device, allowing the load circuit to remain operational.

What is the difference between the MT1 and MT2 suffixes?

The MT2 suffix indicates an automatic retry mode where the device attempts to restore output after cooling down. The MT1 suffix typically denotes a latch-off mode requiring a power cycle or EN pin toggle to reset.
