P9023-2AHGI

Overview

The P9023-2AHGI is an Enhanced Dual-Mode Wireless Power Receiver IC compliant with WPC1.1 and PMA Type 1 standards. It integrates a synchronous full-bridge rectifier, synchronous buck converter, and control circuits to deliver up to 5W output power per Qi specifications. The device supports automatic protocol switching between WPC and PMA modes. Key features include optional back-channel communication, advanced Foreign Object Detection (FOD), and comprehensive protection against over-temperature, overvoltage, and overcurrent conditions.

Feature Summary

• Complies with WPC1.1 and PMA Type 1 certification requirements
• Integrates high-efficiency synchronous rectifier and buck converter
• Supports optional back-channel communication for data exchange
• Includes advanced Foreign Object Detection and multiple protection mechanisms

Applications

• Mobile device wireless charging receivers
• Consumer electronics requiring Qi-compatible power reception
• High-volume strategic applications restricted by manufacturer notice

Procurement Notes

This component is classified as obsolete and has been discontinued by the manufacturer. Availability is limited to existing stock or last-time buys. Verification of end-of-life status and final shipment terms is required before procurement. Alternative solutions such as the P9028AC should be evaluated for new designs due to the discontinuation of this part number.

Selection Notes

Select this component only for legacy system maintenance or specific high-volume strategic contracts where WPC1.1 and PMA Type 1 compatibility is mandatory. Designers must account for the obsolete status when planning long-term supply chains. Consider the integrated nature of the rectifier and buck converter for simplified board layouts in compatible receiver coil configurations.

Part Context

The P9023 series represents Renesas' enhanced dual-mode wireless power receiver solution. It is designed to operate seamlessly with both WPC and PMA transmitter standards. The device simplifies receiver design by combining power conversion and control logic into a single chip, reducing component count and board space compared to discrete solutions.

Replacement Considerations

The P9028AC is identified as a recommended ultra-compact dual-mode wireless power receiver IC substitute. Engineers transitioning from the P9023 should evaluate the P9028AC for pinout compatibility and feature parity to ensure smooth migration to active production parts.
