WP15WBD-RK Bi-directional Data Transfer Evaluation Kit User Manual for the P9221-R3 and P9242-R3 Data sheet
power transfer and bi-directional data communication between a
transmitter (Tx) board with the IDT P9242-R3 Wireless Power
Transmitter IC and a receiver (Rx) board with the IDT P9221-R3
Wireless Power Receiver IC. 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.
This evaluation kit adds bi-directional communication to IDT’s standard, WPC 1.2-compliant, 15W transmitter P9242-R and receiver
P9221-R evaluation kits without compromising any existing
features. Itsmain contents are the transmitter P9242-R3-EVK Evaluation Board and the receiver P9221-R3-EVK Evaluation Board.
In customer end systems, the transmitter and receiver boards need
to have external microcontrollers (MCU) to orchestrate the
bi-directional communication. The MCU on the receiver board
loads data into the user outgoing data registers and triggers the
communication by writing to the Command register. The transmitter
receives the data and interrupts the external MCU on the transmitter pad. The transmitter follows the same procedure to send the
data to the receiver. There are no external MCU’s on the
P9242-R3-EVK and P9221-R3-EVK Evaluation Boards. Instead,
IDT I2C Lite, an intuitive I2C-based graphical user interface (GUI),
and two USB-to-I2C dongles are used to emulate external MCUs.
The USB-to-I2C dongles are included in the kit. The latest version
of the IDT I2C Lite software is available on the IDT webpage.
This manual focuses on demonstrating the bi-directional data communication features of the P9242-R3 and P9221-R3. The P9242-
R3-EVK and P9221-R3-EVK offer the flexibility to program parameters such as the over-current limit and foreign-object detection
(FOD) limits by changing resistors. Refer to the user manuals for
the P9242-R-EVK Transmitter Evaluation Board and P9221-R-EVK
Receiver Evaluation Board for more details related to programming
parameters.
