NCP45651IMNTWG

Overview

The NCP45651IMNTWG is a high-side load switch from onsemi's ecoSWITCH series, designed for efficient power domain switching. It features an N-channel configuration with a maximum output current of 24A and a continuous current rating of 14A. The device supports input voltages up to 13.5V and offers a low on-resistance of 5mΩ. It integrates fault protection mechanisms and inrush current limiting via soft-start functionality. Packaged in a compact 12-pin DFN (3x3mm) surface-mount format, it provides a component and area-reducing solution for power management applications.

Feature Summary

• Integrates inrush current limiting through soft-start functionality for controlled power-up sequences
• Provides comprehensive fault protection mechanisms to safeguard connected loads
• Delivers low on-resistance for improved efficiency in power distribution networks

Applications

• Power domain switching in embedded systems
• Inrush current limiting for capacitive loads
• Fault-protected power distribution in industrial equipment

Procurement Notes

Verify the specific suffix 'L' or absence thereof against the manufacturer's official datasheet, as variants may exist. Confirm the package type is indeed the 12-pin DFN (3x3mm) specified in public documentation. Ensure the operating voltage range aligns with your system requirements before procurement. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a high-side switch with integrated fault protection and soft-start is required. The 14A continuous current rating suits moderate power loads. The 5mΩ on-resistance minimizes power loss. Consider the 13.5V maximum input voltage limit. The compact DFN package aids in space-constrained designs. Verify thermal performance under full load conditions.
