NPS4069GVH

Overview

The NPS4069GVH is a single-channel load switch IC manufactured by Nexperia, designed for power distribution applications. It operates within a supply voltage range of 2.2 V to 5.5 V and supports a maximum continuous output current of 1.5 A. The device features a typical on-resistance of 140 mΩ and includes an adjustable current limit set to 1.83 A. It incorporates built-in soft-start functionality with rise and fall times capped at 3 ms. The component is housed in a TSOP-5 surface-mount package and is rated for operation across an extended temperature range from -40°C to +125°C.

Feature Summary

• Provides active reverse voltage protection to prevent backflow current when powered down.
• Integrates precision adjustable current limiting with constant current regulation during fault conditions.
• Features built-in soft-start capability to control inrush current and manage power sequencing.

Applications

• USB port and hub power switching
• Set-top box power distribution
• High-definition television (HDTV) circuitry
• VoIP telephone power management

Procurement Notes

Verify the specific suffix 'H' against the official Nexperia datasheet to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status directly with the manufacturer or authorized distributor, as regulatory status can vary by production batch. Ensure the selected variant matches the required thermal performance for the intended operating environment.

Selection Notes

Select this component for designs requiring precise current limiting and reverse polarity protection in low-voltage systems. The 1.5 A output capacity suits moderate-load applications such as peripheral interfaces. Evaluate the 140 mΩ on-resistance for potential power dissipation constraints. Verify that the TSOP-5 footprint aligns with the PCB layout requirements and that the 2.2 V minimum start-up voltage is compatible with the system's power rail.

Part Context

This part belongs to the Nexperia NPS40 series of load switches, which are engineered for efficient power management in consumer and industrial electronics. These ICs replace discrete MOSFET solutions to reduce board space and simplify design. The series offers integrated protection features including overcurrent, short-circuit, and thermal shutdown, ensuring robust operation in sensitive digital logic environments.

Replacement Considerations

Consult the official Nexperia product selection guide for verified cross-reference part numbers. Ensure any substitute maintains identical pinout compatibility, voltage ratings, and current limits to guarantee functional equivalence without redesigning the host circuit.
