The RA9460 is a highly-integrated magnetic induction wireless transmitter power stage that supports over 15W of power delivery to a Qi Power Receiver (PRx), and can deliver more than 60W of power with proprietary PRx solutions. The RA9460 works seamlessly with the Renesas RA2E1 MCU family. Precision input current sensing, internal QFOD detection, and bi-directional communication provide for a secure and safe wireless charging experience.
The RA9460 includes an efficient finite state machine for configuration, execution of high-bandwidth tasks (such as Auto-ZVS and QFOD), and uses an external MCU for command and control of the RA9460’s wireless power transfer. The device includes advanced wireless power circuitry such as wide input voltage range operation, high voltage coil MUX control, a phase demodulation signal generator, and auto zeroing input current monitoring. These signals are processed in the RA9460 and then sent to the host MCU’s ADC for FOD, ASK Demodulation, and other tasks related to a wireless power transfer.
In addition, the RA9460 incorporates a USB BCS 1.2 PHY that supports many proprietary Travel Adapter Control Methodologies, and an I2C interface to read or send data, information, and fault conditions to the host MCU. This standard device is compliant to the WPC-1.3 specification. The RA9460 is available in a space-saving 4 × 4 mm 32-VFQFPN package.

A brief overview of the WP15WBD-RK, a 15W WPC Qi-compatible wireless power reference kit featuring a bi-directional communication channel between the transmitter and receiver. The bi-directional 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.
