NX20P0407UKAZ

Overview

The NX20P0407UKAZ is a single-chip USB Type-C port protection IC designed for system-side CC and SBU pins. It provides overvoltage and short-circuit protection against VBUS, withstanding up to 28V DC on CON_CC1/CC2 and CON_SBU1/SBU2. The device features fast OVP shutdown in 60ns, integrated IEC 61000-4-2 ESD protection (15kV air, 8kV contact), and +/-35V surge tolerance. It operates within a 2.5V to 5.5V supply range, consumes 105uA active current, and functions between -40°C and +85°C.

Feature Summary

• Provides robust overvoltage and short-circuit protection for USB Type-C CC and SBU lines against VBUS faults.
• Integrates high-level electrostatic discharge immunity and surge protection directly on connector-side pins.
• Features rapid overvoltage response to isolate sensitive system components from transient voltage spikes.

Applications

• USB Type-C port protection in mobile smartphones
• Protection for USB Type-C interfaces in tablets
• System-side protection for portable consumer electronics

Procurement Notes

Verify the specific suffix UKAZ against official NXP documentation to confirm package type and tape/reel specifications. Ensure compatibility with standard WLCSP-12 mounting requirements. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and current production status before finalizing procurement orders.

Selection Notes

Select this component when designing USB Type-C systems requiring dedicated protection for CC and SBU signals rather than general VBUS switching. It is suitable for applications needing integrated ESD handling alongside overvoltage isolation. Consider its low standby leakage and compact footprint for space-constrained portable designs.

Part Context

This device belongs to NXP's portfolio of USB interface protection solutions, specifically targeting the growing adoption of USB Type-C connectors. It addresses risks associated with mechanical pin shorts and environmental contaminants that may bridge VBUS to sensitive control lines. The series supports modern reversible connector standards while maintaining signal integrity.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify functional equivalence carefully if considering alternatives, as pinouts and protection thresholds may differ significantly across manufacturers.
