P9025AC-RNBGI

Overview

The P9025AC-RNBGI is a single-chip wireless power receiver compliant with the WPC 1.1.2 standard, designed for 5W applications. It integrates a full-bridge synchronous rectifier and a 5.3V, 1A LDO regulator output. The device features advanced Foreign Object Detection (FOD) to enhance safety. Packaged in a 32-pin VFQFPN (5x5 mm) exposed pad format, it supports efficient power transfer for portable electronics requiring standardized wireless charging capabilities.

Feature Summary

• Integrated single-chip solution combining receiver functions with synchronous rectification
• Compliance with Wireless Power Consortium (WPC) 1.1.2 specification
• Advanced Foreign Object Detection (FOD) capability for operational safety
• Built-in 5.3V, 1A Low Dropout (LDO) regulator for downstream power supply

Applications

• Portable consumer electronics requiring 5W wireless charging
• Smartphones and mobile devices supporting WPC 1.1.2 standards
• IoT devices utilizing integrated wireless power reception
• Battery-powered equipment needing compact RF power management

Procurement Notes

Verify component authenticity through authorized Renesas distributors or certified partners. Confirm the specific suffix RNBGI indicates tray packaging when required by assembly processes. Ensure compatibility with existing WPC 1.1.2 transmitter infrastructure. Request original datasheets and RoHS compliance certificates prior to final procurement decisions to guarantee quality standards.

Selection Notes

Select this component for designs strictly adhering to WPC 1.1.2 protocols. The integrated LDO simplifies board layout by providing a regulated output directly from the rectified signal. Consider the 32-VFQFPN package constraints for thermal management and PCB space. This part is suitable where high integration reduces external component count compared to discrete receiver solutions.

Part Context

This model belongs to Renesas' wireless charging IC portfolio, originally developed under IDT before acquisition. It serves as a complete receiver endpoint for inductive power transfer systems. The series focuses on miniaturization and efficiency for mass-market mobile devices, replacing older multi-component receiver architectures with a unified silicon solution.

Replacement Considerations

Check for updated revisions within the P9025AC family. Verify pin-to-pin compatibility if substituting with other Renesas wireless receivers. Ensure any alternative maintains WPC 1.1.2 certification status for regulatory compliance in target markets.
