NIV6150MT1TXG

Current Regulation/Management Overview

The NIV6150MT1TXG is a resettable electronic fuse (eFuse) from onsemi, designed for 5V power distribution applications. It features a maximum on-resistance of 20 mΩ and supports an output current limit of 1.2 A. The device operates within a temperature range of -40°C to +125°C and is housed in a compact 10-WDFNW (3x3 mm) surface-mount package. Certified to AEC-Q100 standards, it provides robust protection against overvoltage, reverse current, and thermal faults. This specific variant utilizes the MT1 suffix, indicating a latch-mode configuration where the device requires a power cycle or enable pin assertion to reset after a fault condition.

Current Regulation/Management Feature Summary

• Integrates overvoltage clamping circuitry to protect loads during transient events without shutting down the system.
• Provides adjustable output current limiting and automatic thermal shutdown to prevent damage from overload conditions.
• Includes digital enable control and a FLAG pin for status monitoring and fault identification.
• Offers integrated reverse current protection to safeguard input circuits against backflow.

Current Regulation/Management Applications

• Automotive infotainment systems
• USB power distribution networks
• Industrial equipment power management

Current Regulation/Management Procurement Notes

Verify the MT1 suffix confirms the required latch-mode behavior for your design, as this variant does not auto-retry. Confirm availability status, as this specific part number may be discontinued or superseded by newer revisions like the MT2 variant. Ensure the WDFNW-10 footprint matches your PCB layout constraints. Check for RoHS compliance documentation if required for your region.

Current Regulation/Management Selection Notes

Select this component when a latching fault response is preferred to force manual intervention after a severe error. Compare with the MT2 variant if automatic recovery after thermal cooldown is desired instead. Ensure the 1.2 A current limit aligns with the load requirements. Verify that the 5 V operating voltage matches the system bus. Consider the 20 mΩ on-resistance impact on power dissipation under full load conditions.

Current Regulation/Management Part Context

This device belongs to the NIS6150/NIV6150 family of automotive-grade eFuses. The NIV series typically denotes industrial/commercial temperature ranges, while the MT1 suffix specifies the latch-mode operation mode. It serves as a protective switch in low-voltage DC distribution networks, replacing traditional fuses with resettable, intelligent protection capabilities.

Current Regulation/Management Replacement Considerations

The manufacturer recommends NIV6150MT2TXG as the replacement. The MT2 variant offers auto-retry functionality instead of latch mode. Verify if the change in fault recovery behavior impacts system safety requirements before substituting.
