NX20P0407UKZ

Overview

The NX20P0407UKZ is a single-chip USB Type-C port protection IC designed to safeguard CC and SBU lines. It provides overvoltage protection with a fast shutdown time of 60ns when voltage exceeds the threshold. The device supports high-speed data rates and operates within a supply voltage range of 2.5V to 5.5V, with a maximum operating voltage of 28V. It features low standby current of 105uA and operates between -40°C and +85°C. Packaged in WLCSP-12 (1.67x1.27mm), it integrates ESD protection rated at 15kV air discharge and 8kV contact discharge.

Feature Summary

• Provides short-circuit and overvoltage protection for CC and SBU pins against VBUS faults
• Integrates robust IEC 61000-4-2 ESD protection on connector-side pins
• Features rapid overvoltage shutdown mechanism to isolate system side from high voltage
• Supports USB Type-C standards with low leakage current for battery-powered devices

Applications

• USB Type-C port protection in mobile smartphones and tablets
• Overvoltage protection for CC and SBU lines in consumer electronics
• Data line protection in portable computing devices
• Interface protection in automotive infotainment systems with USB-C connectivity

Procurement Notes

Verify the specific suffix UKZ matches the required WLCSP-12 packaging and tape-and-reel quantity. Confirm RoHS compliance status through official NXP documentation prior to integration. Ensure design compatibility with USB Type-C 1.0 standards and check for any recent product change notifications that may affect long-term availability or manufacturing location transfers under the longevity program.

Selection Notes

Select this component when dedicated protection for CC and SBU lines is required without affecting VBUS switching capabilities. It is suitable for designs needing integrated ESD protection alongside overvoltage isolation. Consider the low quiescent current for power-sensitive applications. Verify that the WLCSP-12 package size fits the PCB layout constraints compared to larger packages used in other series members.

Part Context

This part belongs to NXP's USB Type-C protection portfolio, distinct from power switches like the NX20P3483 or VBUS protectors like the NX20P5090. It specifically addresses the vulnerability of CC and SBU pins to VBUS shorts caused by mechanical misalignment or environmental factors. It complements other interface ICs by providing targeted signal line integrity rather than power delivery management.

Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Designers should evaluate form, fit, and function compatibility carefully if migrating from legacy components. Consult NXP for recommended alternatives if this specific WLCSP-12 variant becomes unavailable.
