P9035A-0NTGI8

Overview

The P9035A-0NTGI8 is a highly integrated wireless power transmitter IC compliant with the WPC 1.1 standard, designed for A5 and A11 transmitter applications. It operates from a 5V (±5%) adapter and utilizes an external full-bridge inverter to provide efficient power transfer. The device controls transferred power by modulating the switching frequency of the inverter between 110kHz and 205kHz at a fixed 50% duty cycle. It includes logic circuits to demodulate and decode message packets sent by mobile devices to adjust power levels accordingly.

Feature Summary

• Complies with Wireless Power Consortium (WPC) 1.1 standard specifications
• Integrates logic circuits for demodulation and decoding of mobile device messages
• Controls power transfer via frequency modulation of an external full-bridge inverter

Applications

• Wireless power transmitter design A5
• Wireless power transmitter design A11
• Mobile device charging systems

Procurement Notes

Verify the specific suffix -0NTGI8 against official Renesas documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with WPC 1.1 compliance testing requirements for A5/A11 transmitters. Confirm that the external full-bridge inverter components meet the required voltage and current ratings for the intended application.

Selection Notes

Select this component for designs requiring strict adherence to WPC 1.1 standards for A5 or A11 form factors. It is suitable for applications needing integrated message decoding and frequency-based power control. Consider the requirement for an external full-bridge inverter when evaluating board space and bill of materials.

Part Context

The P9035A belongs to the IDT family of wireless power transmitter solutions acquired by Renesas. It is specifically engineered for Qi-compliant charging bases, offering a compact solution for consumer electronics manufacturers aiming to support standardized wireless charging protocols without complex discrete implementations.

Replacement Considerations

Check Renesas official cross-reference lists for direct replacements. Verify if newer revisions maintain identical pinout and WPC 1.1 compliance.
