The P9036 evaluation board serves to demonstrate the features and performance of the P9036 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 board provides numerous test points to allow detailed signal inspection access at different nodes of the circuit to better understand the key functionality of the system. 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 programmer 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 a specific application using the P9036 software tool.
