NX5P3201CUKAZ

Overview

The NX5P3201CUKAZ is a logic-controlled high-side power switch designed for USB PD applications. It features an adjustable current limit, UVLO, OVP, reverse current protection, and over-temperature protection. The device supports VBUS withstand up to 29V and includes soft-start functionality to minimize inrush current. An open-drain fault output indicates failure conditions. The ILIM pin sets the current threshold via an external resistor. It utilizes a 12-ball WLCSP package with dimensions of 1.35 x 1.65 mm and 0.4 mm pitch.

Feature Summary

• Integrates precise programmable current limiting and comprehensive protection circuits including UVLO, OVP, and thermal shutdown.
• Features built-in soft-start and surge protection mechanisms to control rise/fall times and enhance system durability during switching events.
• Includes integrated logic level translation on the enable input to ensure compatibility with low-voltage processors and controllers.

Applications

• USB Power Delivery (PD) port load switching
• High-side power distribution in mobile devices
• Surge protection for VBUS lines

Procurement Notes

Verify the specific suffix 'UKAZ' against official NXP documentation to confirm exact tape-and-reel packaging specifications and marking codes. Ensure the design accounts for the 12-ball WLCSP footprint dimensions and thermal requirements as defined in the datasheet. Cross-reference the ILIM resistor values to guarantee the current limit falls within the specified operational range for the target application.

Selection Notes

Select this component when designing USB PD interfaces requiring adjustable current limiting and robust fault protection. It is suitable for applications needing logic-level control from low-voltage MCUs. Consider the WLCSP package size constraints and the need for external resistors to program the current threshold and fault behavior compared to fixed-limit alternatives.

Part Context

This part belongs to NXP's family of logic-controlled high-side power switches tailored for USB Type-C and PD ecosystems. It complements other VBUS protection devices like the NX5P3090 and NX20P5090 by offering similar protection features in a compact form factor. The series addresses the growing demand for efficient, protected power delivery in modern consumer electronics and computing platforms.
