P9028-1AWGI

Overview

The P9028-1AWGI is an ultra-compact dual-mode wireless power receiver IC compliant with WPC v1.1 and 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 supports automatic mode switching between WPC AC and PMA DC modulation for improved efficiency. It features advanced programmable Foreign Object Detection (FOD) via external resistors and I2C registers, closed-loop power transfer control, and comprehensive protection against over-temperature, overvoltage, and overcurrent conditions.

Feature Summary

• Dual-mode operation supporting both WPC v1.1 and PMA protocols
• Integrated synchronous full-bridge rectifier and 5V tracking LDO
• Advanced programmable Foreign Object Detection (FOD)
• Closed-loop power transfer control with I2C interface

Applications

• Wireless charging receivers for mobile devices
• Consumer electronics requiring Qi-compliant power input
• Automotive infotainment systems with wireless charging capabilities

Procurement Notes

Verify the exact suffix '1AWGI' against official Renesas documentation, as standard listings often reference 'P9028AC'. Confirm package type WLCSP and lead count specifications. Ensure sourcing channels are authorized due to strategic application restrictions. Check for end-of-life status or obsolescence notices prior to procurement.

Selection Notes

Select this component for applications requiring compact dual-mode wireless power reception. It is suitable where minimal external components are desired to reduce solution area. Consider its integration of FOD and protection features for safety-critical designs. Evaluate compatibility with existing transmitter base stations supporting WPC v1.1 or PMA standards.

Part Context

The P9028 series serves as an enhanced dual-mode wireless power receiver within Renesas's portfolio. It succeeds earlier models like the P9023, offering improved integration and compliance with updated WPC v1.1 standards. The device is designed for high-volume strategic applications in the consumer electronics sector.

Replacement Considerations

The P9023 is listed as an obsolete predecessor. Verify functional equivalence if substituting. No other direct public substitutes are confirmed in the provided data.
