P9035-0NTGI

Overview

The P9035-0NTGI is a wireless power transmitter IC compliant with WPC 1.1 specifications, designed for A5 and A11 power transmitter configurations. It operates from a 5V input supply and utilizes an external full-bridge inverter to generate the required RF field. The device features integrated demodulation and decoding logic for WPC-compliant message packets, enabling closed-loop power transfer control between the base station and mobile device. Key electrical parameters include a maximum output power of 8W, an operating supply voltage range of 4.5V to 6.9V, and a maximum operating current of 45mA. It supports frequencies from 110kHz to 205kHz and includes over-temperature and over-current protection.

Feature Summary

• Complies with Wireless Power Consortium (WPC) version 1.1 standards for A5/A11 transmitter designs
• Integrates logic circuits to demodulate and decode WPC-compliant message packets from mobile devices
• Controls transferred power by modulating the switching frequency of an external full-bridge inverter
• Includes proprietary back-channel communication capabilities and I2C interface support

Applications

• Wireless charging base stations conforming to WPC 1.1 specifications
• A5 and A11 power transmitter implementations
• Closed-loop power transfer systems between base stations and mobile devices

Procurement Notes

Verify component authenticity through authorized Renesas distributors or official channels. Confirm package integrity and moisture sensitivity level handling procedures prior to assembly. Ensure compatibility with external full-bridge inverter components and verify that the design adheres to WPC 1.1 electromagnetic interference requirements. Check for obsolescence status as this part may be discontinued.

Selection Notes

Select this IC for designs requiring strict adherence to WPC 1.1 standards for A5/A11 transmitters. It is suitable for applications needing integrated packet demodulation and closed-loop power control without external microcontrollers for basic operation. Consider the requirement for an external full-bridge inverter and associated passive components when evaluating board space and bill of materials.
