BQ24085EVM is a wireless power transfer evaluation and development board developed by Texas Instruments. It is a BCB (black small board) solution for wireless power applications. The BQ24085EVM Application Field and Working Principle is used to develop and test the various functions of the wireless power transfer. The evaluation board is designed for WPC (Wireless Power Consortium) based Qi standard wireless power transfer applications.

The evaluation board consists of a BQ24085EVM main board, a WPC addition board (WPCAB), and a 9V AC adapter. The main board contains the BQ24085EVM power management IC, which integrates the wireless power transfer functionality into a single solution. The WPCAB provides the wireless power transmission and reception features required to evaluate the BQ24085EVM.

BQ24085EVM is a Qi-compatible transmitter and receiver. It supports both 5W magnetic induction and 15W resonant wireless power transfer. The board includes an RF generator, antenna, and power monitor, which can simplify system characterization and optimize design performance. The board also includes DC power input and output pads, two push-button switches, eight LED indicators, and a USB port.

BQ24085EVM works by synchronizing the signal from the receiver to the transmitter during power transfer. When a wireless device is placed in the transmission field, the wireless transmission from the receiver to the transmitter is initiated. Then the receiver will detect the transmitted signal and will begin the process of power transfer. During the transfer process, the receiver and transmitter communicate to ensure a positive power transfer experience.

The BQ24085EVM also has the capability to monitor the power transfer performance during the wireless power transfer. This enables the device to optimize the power transfer by detecting any power errors. The integrated power monitor can provide current and voltage information which can be used to detect the presence of products and further optimize the power transfer system.

The BQ24085EVM evaluation board also provides ease of application enablement and system development. The board supports multiple configurations for wireless power transfer and has various features which can be adjusted such as receiver sensitivity, output voltage range, power output range, and much more. The board also includes user-friendly GUI graphical operating software for easy testing and monitoring.

In conclusion, BQ24085EVM is a comprehensive evaluation and test board for wireless power transfer applications developed for WPC (Wireless Power Consortium) based Qi standard. Its advanced integration technology improves system performance, reduces system size and improves efficiency. It provides user-friendly graphical user interface and various features which can be adjusted to customize the wireless power transfer system. It is an ideal development board for wireless power applications.
