NCP45523IMNTWG-H

Overview

The onsemi NCP45523IMNTWG-H is an ecoSWITCH high-performance N-Channel power switch IC designed for demanding power distribution applications. It features a low on-state resistance of 31.7mΩ and supports a maximum continuous current of 6A. The device operates within a supply voltage range up to 5.5V and dissipates up to 2.5W of power. Packaged in an 8-pin DFN format, it integrates protection mechanisms including thermal shutdown and overcurrent limiting to ensure system reliability.

Feature Summary

• Integrates a high-efficiency N-Channel MOSFET with ultra-low on-resistance for minimal power loss
• Provides comprehensive system protection through integrated thermal shutdown and fault management
• Supports controlled load switching with soft-start capabilities to limit inrush currents

Applications

• Power distribution networks in portable electronic devices
• Peripheral port protection in computing systems
• Hot-pluggable interface circuits requiring surge current limiting

Procurement Notes

Verify the specific suffix H against official datasheets to confirm pinout and electrical tolerances. Confirm RoHS compliance status directly with the manufacturer or authorized distributors. Ensure the DFN-8 package dimensions match your PCB footprint requirements. Check for obsolescence notices as component lifecycles may change without prior announcement.

Selection Notes

Select this component when a compact solution with high current handling capability is required. The 31.7mΩ on-resistance makes it suitable for applications prioritizing efficiency over cost. Consider the 5.5V input limit when designing for higher voltage rails. The integrated protection features reduce the need for external discrete components, simplifying the bill of materials.

Part Context

This part belongs to the onsemi ecoSWITCH family of power switches. These devices are engineered to replace traditional discrete FET and diode combinations. The series offers various configurations tailored for different current and voltage requirements. The NCP45523 variant specifically targets mid-range current applications in space-constrained designs.

Replacement Considerations

Consult official substitution guides for compatible alternatives. Verify that any substitute matches the 8DFN package and 6A current rating. Ensure equivalent on-resistance and protection feature sets are maintained.
