NPS4001GVH

Overview

The NPS4001GVH is a single-channel load switch IC manufactured by Nexperia, designed for power distribution applications. It operates within an input voltage range of 2.2 V to 5.5 V and supports a rated output current of 2 A. The device features a maximum on-resistance of 140 mΩ and includes built-in current limiting with a threshold of 2.37 A. Packaged in a TSOP-5 (SOT753) surface-mount format, it provides active reverse voltage protection and an open-drain flag output for fault indication.

Feature Summary

• Integrates constant-current mode for precise output current limitation during overload or short-circuit conditions
• Features active reverse voltage protection that disables the switch if output voltage exceeds input voltage
• Includes an active-low flag pin to signal overcurrent, over-temperature, and reverse voltage faults

Applications

• USB ports and hubs in laptops, docking stations, and desktops
• Set-top boxes and HDTV systems
• Optical socket protection circuits
• General current limiting circuits requiring robust fault management

Procurement Notes

Verify the specific suffix GVH against the manufacturer's official datasheet to confirm package type and electrical tolerances. Confirm availability status as supply may be limited or subject to factory special orders. Ensure the selected variant matches the required operating temperature range and ESD protection levels for the target application environment.

Selection Notes

Select this component when designing power distribution networks requiring integrated current limiting and reverse polarity protection. The low on-resistance minimizes power loss, while the flag output simplifies system monitoring. Ensure the load capacitor meets minimum requirements for stability, particularly in USB applications where at least 120 μF is recommended.
