X-NX20P0407UK

Overview

The NX20P0407UKZ is a single-chip USB Type-C port protection solution designed to safeguard system-side CC and SBU pins. It provides overvoltage and short-circuit protection against VBUS, withstanding up to 28V DC on connector pins. The device features fast OVP shutdown in 60ns, integrated IEC 61000-4-2 ESD protection (15kV air, 8kV contact), and low leakage current of 32uA. It includes Rd circuit battery drain for CC pins and offers low on-resistance switches (160mΩ for CC, 3.6Ω for SBU).

Feature Summary

• Provides short-circuit and overvoltage protection for USB Type-C CC1/CC2 and SBU1/SBU2 pins against VBUS.
• Integrates high-level ESD immunity with 15kV air discharge and 8kV contact discharge ratings per IEC 61000-4-2.
• Features rapid overvoltage protection response time of 60ns to disconnect faulty connections quickly.
• Includes built-in Rd circuit battery drain functionality for CC pins to support dead battery operations.

Applications

• USB Type-C port protection in mobile devices and smartphones
• Protection for CC and SBU lines in consumer electronics
• System-side interface protection in portable computing hardware

Procurement Notes

Verify the exact ordering part number suffix, as 'NX20P0407UKZ' indicates specific packaging or tape-and-reel configuration. Confirm package type WLCSP-12 matches your PCB layout requirements. Ensure voltage tolerances align with your system's VBUS specifications before integration.

Selection Notes

Select this component when robust protection for USB Type-C communication lines is required without external discrete components. It is suitable for designs needing integrated ESD handling and fast overvoltage response. Consider its low leakage characteristics for power-sensitive applications and its compact WLCSP footprint for space-constrained layouts.
