P9028AC-1AWGI

Overview

The P9028AC-1AWGI is an ultra-compact dual-mode wireless power receiver IC compliant with WPC v1.1 and compatible with PMA standards. It integrates a synchronous full-bridge rectifier and a 5V tracking LDO output stage to convert AC signals from a resonant tank into regulated DC voltage. The device supports automatic dual-mode operation for improved efficiency and includes advanced programmable Foreign Object Detection (FOD). It features an I2C interface for monitoring Vrect, Iout, and switching frequency, along with closed-loop power transfer control between transmitter and receiver.

Feature Summary

• Dual-mode operation supporting both WPC v1.1 and PMA protocols
• Integrated synchronous full-bridge rectifier and 5V tracking LDO regulator
• Advanced programmable Foreign Object Detection (FOD) via external resistor and I2C registers
• I2C interface for real-time monitoring of electrical parameters

Applications

• Mobile device wireless charging receivers
• Consumer electronics requiring Qi-compliant power input
• Automotive infotainment systems with wireless charging capabilities
• IoT devices utilizing dual-mode wireless power reception

Procurement Notes

Verify the specific suffix '1AWGI' against official Renesas documentation to confirm pinout and package variations. Confirm availability status as the base model may be obsolete or restricted. Ensure compliance with high-volume application restrictions if applicable. Check for moisture sensitivity level and lead-free certification details in the final datasheet before integration.

Selection Notes

Select this component for applications requiring a single-chip solution for both WPC and PMA standards. The integrated FOD and minimal external component count reduce board space. Consider the WLCSP package constraints for high-density designs. Verify thermal performance requirements due to the compact form factor and integrated regulation.

Part Context

The P9028AC series represents Renesas's ultra-compact wireless power receiver family. It is designed to replace discrete solutions by integrating rectification, regulation, and control logic. The device targets mobile and consumer markets needing certified Qi and PMA compatibility in a small footprint.

Replacement Considerations

The P9023 is a documented alternative within the same product line offering similar dual-mode capabilities. Verify pin-to-pin compatibility and software configuration differences when substituting. Ensure the replacement meets the specific WPC v1.1 and PMA requirements of the target design.
