Evaluation Board for Wireless Power Transmitter P9036A
The P9036A-TX-A6 evaluation board serves to demonstrate the features and performance of the P9036A wireless power charging solution for base stations with a Tx-A6 coil transmitter. The three-coil transmitter system enables a large active power area with high efficiency transfer and enables power to only one coil at a time when the Receiver is detected. The design allows detailed signal inspection of different nodes using various testing points. The evaluation module is a stand-alone application; all it needs is a 12V/1A DC power adapter and a WPC certified power receiver.
Optionally the EVM’s activity can be monitored by I2C communication and GUI (graphical user interface) software through a USB cabled JM60 dongle board, which interfaces the EVM to the computer. The MAIN tab of the software tool provides real time plots of coil current, PWM frequency, and duty cycle, including different states of the microcontroller and FOD (foreign object detection). The evaluation board utilizes an external EEPROM which contains Tx firmware to enable programmability. The external EEPROM memory chip is pre-programmed with a standard start-up program that is automatically loaded when 12V power is applied. The EEPROM can be reprogrammed to suit the needs of specific applications using the P9036A software tool.
