NIS6452MT1TWG

Current Regulation/Management Overview

The NIS6452MT1TWG is a 5V resettable electronic fuse (eFuse) from onsemi, designed for circuit protection in storage and computing applications. It features a WQFN-12 package with SMD/SMT mounting. Key electrical parameters include a maximum voltage of 15 VDC, a maximum rated current of 5 A, and a typical resistance of 60 mOhms. The device operates within a temperature range of -40°C to +125°C.

Current Regulation/Management Feature Summary

• Integrates reverse current protection to safeguard input circuits against backflow during power failures or noise interference.
• Includes overvoltage clamp circuitry that limits output voltage during input transients to protect sensitive load devices.
• Features thermal protection that automatically shuts down the device when the power FET junction temperature reaches 175°C.

Current Regulation/Management Applications

• Hard drive circuit protection
• Motherboard power distribution
• Solid state drive (SSD) protection

Current Regulation/Management Procurement Notes

Verify the specific suffix MT1 versus MT2 to ensure correct packaging and variant alignment with design requirements. Confirm RoHS compliance status through official documentation before integration. Cross-reference the datasheet for precise pinout and thermal pad specifications to match PCB layout constraints accurately.

Current Regulation/Management Selection Notes

Select this component for 5V bus protection where low on-resistance and compact WQFN-12 footprint are critical. Ensure the application does not exceed the 15 VDC maximum rating or 5 A continuous current limit. Consider the integrated soft-start and current monitoring capabilities if system stability and diagnostics are required.

Current Regulation/Management Part Context

Part of the NIS64x2 series of cost-effective resettable electronic fuses. This family enhances reliability in hard drives and other circuits by buffering loads against high input voltages and protecting inputs from reverse currents. The series supports digital and tri-state enable controls for flexible system management.

Current Regulation/Management Replacement Considerations

NIS6452MT2TWG is a related variant within the same product family. Verify functional equivalence and packaging compatibility before substitution. Consult the manufacturer's cross-reference guide for detailed differences between MT1 and MT2 suffixes.
