NIS5420MT5TXG

Current Regulation/Management Overview

The onsemi NIS5420MT5TXG is a self-protected high-side electronic fuse (eFuse) belonging to the SENSEFET series. It operates within an input voltage range of 8V to 18V and supports a maximum output current of 4.6A. The device features a low on-resistance of 50 mOhms and is housed in a compact 10-WDFN package with dimensions of 3mm x 3mm and a height of 0.8mm. It is designed for surface-mount installation and functions reliably across a temperature range of -40°C to +125°C.

Current Regulation/Management Feature Summary

• Integrates self-protection mechanisms for high-side power switching applications
• Utilizes SENSEFET technology for precise current sensing and management
• Provides robust thermal and electrical protection in a miniature footprint

Current Regulation/Management Applications

• High-side load switching in automotive electronics
• Power distribution units requiring overcurrent protection
• Hot-plug insertion systems with startup time delay capabilities

Current Regulation/Management Procurement Notes

Verify the specific suffix 'MT5' against official datasheets to confirm pinout and functional configuration, as suffixes often denote distinct variants within the same family. Ensure compatibility with RoHS3 standards and check for any recent Product Change Notifications or End-of-Life announcements from onsemi before finalizing procurement plans.

Current Regulation/Management Selection Notes

Select this component when a compact, high-current eFuse solution is required for 12V nominal systems. The 4.6A rating and 50 mOhms resistance offer a balance between conduction loss and protection capability. Consider the 10-WDFN package constraints for PCB layout and thermal dissipation requirements compared to larger packages.

Current Regulation/Management Part Context

This part belongs to the NIS5420 series of electronic fuses from onsemi. The series is characterized by integrated sense FETs that combine power switching and current monitoring in a single device. This integration simplifies circuit design by reducing the component count needed for high-side protection and control applications.
