NX5P3290UKZ

Overview

The NX5P3290UKZ is a USB PD and Type-C current-limited power switch manufactured by NXP Semiconductors. It features a single P-channel output configured as a high-side switch within a 16-WLCSP package measuring 2.05x2.05 mm. The device operates with a supply voltage range of 4 V to 5.5 V and supports an output current limit adjustable between 400 mA and 3.3 A. Key electrical characteristics include a maximum on-resistance of 42 mOhms, a maximum turn-on time of 750 us, and a maximum idle time of 70 us. It functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrated fault protection including adjustable current limiting, over-temperature shutdown, reverse current blocking, and under-voltage lockout.
• Controlled slew rate functionality to minimize inrush current during power-up sequences.
• Status flag output for monitoring operational state and fault conditions.

Applications

• USB Power Delivery (PD) source port implementation
• USB Type-C connector VBUS protection circuits
• Current-limited power distribution in mobile devices

Procurement Notes

Verify the specific suffix UKZ against the official NXP datasheet to confirm pinout and packaging details. Ensure compatibility with system voltage requirements of 4V to 5.5V. Confirm that the WLCSP-16 package dimensions align with the PCB footprint design. Check for RoHS compliance status if required by project specifications.

Selection Notes

Select this component when designing USB Type-C interfaces requiring precise current limiting and robust fault protection. The integrated slew rate control makes it suitable for applications sensitive to inrush currents. Verify that the adjustable current limit range meets the load requirements. Consider the small WLCSP footprint for space-constrained designs.

Part Context

This part belongs to the NX5P3290UK series of USB PD and Type-C current-limited power switches. It is designed specifically for VBUS protection and power distribution in modern USB-C applications. The series offers integrated protection features to safeguard downstream components from overcurrent and thermal events.

Replacement Considerations

Consult the official NXP substitution guide for form-fit-function compatible alternatives. Verify that any substitute maintains the same WLCSP-16 package and pin configuration. Ensure equivalent electrical parameters for current limiting and voltage ranges.
