NIS5452MT1TWG

Current Regulation/Management Overview

The onsemi NIS5452MT1TWG is a 5V electronic fuse designed for circuit protection. It features a maximum rated current of 5A and a low on-resistance of 60 mOhms. The device operates within a voltage range up to 15 VDC and supports surface mount installation in a WQFN-12 package. It functions as a resettable PPTC-style fuse with integrated control capabilities.

Current Regulation/Management Feature Summary

• Integrates reverse current protection to prevent backflow damage during power failures or noise events.
• Includes overvoltage clamp circuitry to limit output voltage during input transients.
• Features thermal shutdown protection that activates at high junction temperatures.

Current Regulation/Management Applications

• Hard drive circuit protection
• General electronic circuit overload protection
• Input side circuit safeguarding

Current Regulation/Management Procurement Notes

Verify the specific suffix MT1T against official datasheets to confirm pinout and packaging details, as suffixes define mechanical attributes. Ensure compatibility with WQFN-12 footprint requirements. Confirm RoHS compliance status through manufacturer documentation before integration into final assemblies.

Current Regulation/Management Selection Notes

Select this component for applications requiring 5V operation with up to 5A load capacity. The low on-resistance minimizes power loss. Consider the WQFN-12 package for space-constrained PCB designs. Verify that the integrated protection features align with system safety requirements without external components.

Current Regulation/Management Part Context

This part belongs to the NIS54x2 series of electronic fuses from onsemi. These devices are engineered to replace traditional fuses, offering resettable protection. The series focuses on enhancing reliability in sensitive electronics by preventing catastrophic failures caused by electrical faults.

Current Regulation/Management Replacement Considerations

NIS5452MT1TXG serves as a verified substitute within the same family, sharing identical electrical characteristics and functionality while potentially differing only in packaging or tape-and-reel specifications.
