Overview
Description
The WP15WBD-RK evaluation kit demonstrates 15W wireless power transfer and bidirectional data communication between a transmitter (Tx) board with the P9242-R3 wireless power transmitter IC and a receiver (Rx) board with the P9221-R3 wireless power receiver IC. The bidirectional data communication channel enables users to authenticate a wirelessly charged receiver device with a specific charging transmitter base or to transfer system data without any additional hardware.
This evaluation kit adds bidirectional communication to Renesas’s standard, WPC 1.2 compliant, 15W transmitter P9242-R and receiver P9221-R evaluation kits without compromising any existing features. Its main contents are the transmitter P9242-R3-EVK Evaluation Board and the receiver P9221-R3-EVK Evaluation Board.
Features
- Supports bidirectional data communication

Wireless power transfer uses an air-core transformer with separate transmitter and receiver coils, making accurate performance modeling difficult due to low magnetic coupling and increased losses. This paper addresses simulation challenges and describes methods to approximate circuit behavior. It demonstrates best practices for tuning Qi and PMA inductive resonance circuits to maximize charging efficiency for mobile devices.

- P9242-R3 --> P9222 proprietary data transfer
Hello! We've got a WP15WBD-RK Bi-directional Data Transfer Evaluation Kit with P9242-R3 power transmitter. Our engineers have designed a custom PCB equipped with wireless power receiver P9222-R. By programming P9222 registers I'm able to send 4 proprietary bytes to P9242-R3, the power transmitter ...
