Procurement Notes
Verify the complete part number including the suffix AZ against official NXP documentation to ensure correct packaging and material declaration compliance. Confirm RoHS and halogen-free status requirements match project specifications. Check moisture sensitivity level and peak reflow temperature limits during assembly planning to prevent package damage. Ensure the supplier provides valid certificates of analysis for quality assurance.
Selection Notes
Select this component when designing USB Type-C interfaces requiring combined sink and source switching functionality. It is suitable for applications needing high-voltage tolerance and integrated protection features. Consider the WLCSP-42 package constraints for PCB layout. Verify that the I2C control interface aligns with the host controller's available bus lines and voltage levels.
Part Context
This device belongs to the NX20P3483UK series of USB interface ICs designed for power delivery applications. It complements other NXP solutions like the NX20P5090UK for unidirectional switching or NX20P0407 for CC/SBU protection. The series targets mobile devices and chargers, offering compact integration for modern USB-C ecosystems.
