Procurement Notes

Verify component authenticity through authorized Infineon distributors or official channels. Confirm the specific suffix 'Q' denotes the tray packaging variant if required by assembly processes. Check current lifecycle status as discontinuation notifications may apply. Ensure compliance with RoHS directives and relevant safety standards before integration into final products.

Selection Notes

Select this model for designs requiring integrated USB-PD sink functionality alongside high-power wireless transmission. Consider the 68-QFN package constraints for PCB layout and thermal dissipation requirements. Evaluate compatibility with existing coil designs and foreign object detection tuning guidelines provided in application notes.

Part Context
