P9028A-3AWGI8

Overview

The P9028A-3AWGI8 is an ultra-compact dual-mode wireless power receiver integrated circuit manufactured by Renesas Electronics Corporation. It complies with WPC1.1 and PMA Type 1 standards for certification, supporting Qi mode power transfer up to 5W. The device integrates a high-efficiency synchronous rectifier, a synchronous buck converter, and control circuits within a small footprint. Key electrical characteristics include support for optional back-channel communication and advanced Foreign Object Detection (FOD). Protection features encompass over-temperature, overvoltage, and overcurrent safeguards. The component utilizes a WLCSP package configuration suitable for space-constrained mobile applications.

Feature Summary

• Complies with WPC1.1 and PMA Type 1 certification requirements
• Integrates synchronous full-bridge rectifier and buck converter
• Supports automatic protocol switching between WPC and PMA
• Includes advanced Foreign Object Detection (FOD)

Applications

• Wireless charging receivers for smartphones

Procurement Notes

Verify the specific suffix '3AWGI8' against official Renesas documentation to confirm package type and temperature grade. Confirm current availability status as previous models in this series have been marked obsolete. Ensure compatibility with existing coil designs and controller firmware before integration. Request updated datasheets and application notes directly from the manufacturer or authorized distributors to validate pinout and electrical specifications.

Selection Notes

Select this component when designing systems requiring dual-mode (WPC/PMA) compatibility within a minimal form factor. The integrated synchronous rectification and buck conversion reduce external component count compared to discrete solutions. Consider the device's protection features for robust operation in varying environmental conditions. Evaluate the need for back-channel communication capabilities if bidirectional data exchange is required for the specific application protocol.

Part Context

The P9028A series represents Renesas' evolution in wireless power reception technology, succeeding earlier models like the P9023. This generation focuses on enhanced efficiency and compactness through advanced integration. The device targets the growing market for standardized wireless charging in mobile and portable devices. It maintains backward compatibility with established charging standards while offering improved performance metrics for modern power delivery requirements.

Replacement Considerations

The P9023AC is documented as a related product in the same family. Verify functional equivalence and pinout compatibility before substitution. Check for any differences in thermal performance or certification status between the legacy and replacement parts.
