NX3P2902BUKZ

Overview

The NX3P2902BUKZ is a logic-controlled high-side power switch manufactured by NXP Semiconductors. It provides single-channel output with a maximum continuous current of 1 A and features a maximum on-resistance of 150 mΩ. The device operates within a supply voltage range of 1.1 V to 3.6 V, supporting minimum and maximum operating temperatures of -40 °C and +85 °C respectively. Key timing parameters include a maximum turn-on time of 570 µs and a maximum idle time of 200 µs. It is designed for surface-mount installation in compact electronic applications.

Feature Summary

Logic-controlled high-side power switching capability
Integrated soft-start functionality to manage inrush currents
Compatibility with low-voltage processors via level shifting

Applications

Smartwatch power distribution
Fitness tracker circuit design
Compact wearable device subsystems

Procurement Notes

Verify the specific suffix 'BUKZ' against official NXP documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with target PCB footprint dimensions and soldering profiles. Confirm RoHS compliance status through the manufacturer's certification documents prior to integration into final assemblies.

Selection Notes

Select this component for space-constrained portable electronics requiring efficient high-side load management. The integrated logic interface simplifies control from microcontrollers without additional level-shifting circuits. Evaluate thermal performance under maximum load conditions to ensure reliable operation within the specified temperature range.

Part Context

This part belongs to NXP's portfolio of small, tiny-package load switches designed for point-of-load power distribution. It complements other series like the NX5P2924 and NX3P1108, offering tailored solutions for varying current and voltage requirements in modern mobile and wearable device architectures.
