P9028A-0AWGI8

Overview

The P9028A-0AWGI8 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 regulator to convert AC signals from a resonant tank into regulated DC output. The device features advanced programmable foreign object detection (FOD) via external resistors and I2C registers, closed-loop power transfer control, and temperature monitoring through an external NTC thermistor. It operates within a specified voltage range and includes comprehensive protection mechanisms such as over-temperature, overvoltage, and overcurrent safeguards.

Feature Summary

• Dual-mode operation supporting both WPC v1.1 and PMA compatible protocols for improved efficiency
• Integrated high-efficiency synchronous full-bridge rectifier and 5V tracking LDO output stage
• Advanced programmable foreign object detection (FOD) techniques using transmitted and received power transfer algorithms
• Closed-loop power transfer control between transmitter and receiver with I2C interface for status monitoring

Applications

• Mobile application power supply units requiring WPC v1.1 compliance
• Automatic dual-mode wireless charging bases utilizing AC or DC modulation connections
• Compact consumer electronics with strict space constraints for receiver circuitry

Procurement Notes

Verify the exact suffix against official Renesas documentation to confirm package type and moisture sensitivity level. Confirm availability status as this component may be restricted to high-volume strategic applications. Ensure compatibility with existing resonant tank designs and FOD configuration requirements before procurement.

Selection Notes

Select this IC for applications requiring a single-chip solution for dual-mode wireless power reception. Consider the integrated FOD capabilities and minimal external component count when designing for size-constrained environments. Verify that the required output current and voltage regulation meet the target mobile application specifications.
