NCP81295MNTXG

Current Regulation/Management Overview

The NCP81295MNTXG is a hot-swap smart fuse and voltage controller manufactured by onsemi. It functions as an electronically re-settable in-line fuse designed for high-current applications operating at 12V with up to 50A current capacity. The device features a low on-state resistance of 0.65mΩ, ensuring minimal power loss during conduction. It is housed in a QFN32 surface-mount package suitable for automated assembly. The component supports operation across a temperature range from -40°C to +125°C, providing robust performance in demanding environments.

Current Regulation/Management Feature Summary

• Electronically re-settable in-line fuse functionality
• Hot-swap capability for live insertion and removal
• Low on-state resistance for efficient power handling

Current Regulation/Management Applications

• Server systems requiring high-current protection
• Storage arrays needing hot-swap support
• Base station infrastructure components

Current Regulation/Management Procurement Notes

Verify the specific suffix MNTXG against the official datasheet to confirm package type and tape/reel specifications. Ensure compatibility with 12V system architectures and 50A load requirements before procurement. Confirm RoHS compliance status through manufacturer documentation if required for regulatory adherence.

Current Regulation/Management Selection Notes

Select this component when active hot-swap protection and precise current limiting are required for 12V systems. The integrated smart fuse design simplifies circuit topology by combining switching control with overcurrent protection. Consider thermal management solutions given the 50A current rating and QFN32 package constraints.
