Evaluation and Demonstration Boards and Kits are used by developers to bring out the full potential of a given chip set. The evaluation board BQ51050BEVM-764 is an excellent example of such a tool, allowing developers to fully test and evaluate a chip set before committing to a full product design. This particular evaluation board works in conjunction with TI\'s BQ51050, a highly efficient 5-channel Wireless Power Transmitter IC. This chip set was designed for use in wireless charging applications before being more generally adopted in products such as true wireless headphones, earbuds, and other wearables.

The BQ51050BEVM-764 makes use of a 5-path charging approach, allowing for simultaneous charging of up to 5 compatible receiver devices. Each path is allocated 15 watts of power, with a total of 75 watts available. For added convenience and flexibility, the BQ51050BEVM-764 also supports both WPC-V1.2 and PMA protocols. This allows the power board to be used with the broadest range of applications.

At the heart of the BQ51050BEVM-764 is the 5-channel BQ51050, which provides the necessary power to charge compatible wireless devices. The BQ51050 incorporates a variety of features to ensure safe and optimal charging. Its secondary side architecture uses a highly-integrated, low-quiescent current pass device to boost voltage between the power board and the receiver device. This provides an efficient output power supply, producing high voltage conversion efficiencies. The companion driver IC ensures stability and flexibility, while the built-in safety functions prevent damage to the device due to overvoltage or overcurrent conditions.

The BQ51050BEVM-764 makes use of TI\'s QfnEVB board, which provides a complete hardware solution for evaluating and programming the BQ51050 chip. The board includes a wide range of components, such as inductors, capacitors, and resistors, that allow it to be used with various wireless charging projects. In addition, it includes a voltage-control loop and an integrated voltage supervisor circuit, which provides protection against overvoltage, overcurrent, and overtemperature conditions. Furthermore, the board is designed in a TI-standard 0.4mmQFN footprint for compatibility with the latest QFN packages.

The BQ51050BEVM-764 is a powerful tool for evaluating and developing applications that rely on wireless charging. Thanks to its wide range of features, it can be used in a variety of projects that require optimized power transfer and intelligent control. By giving developers the ability to evaluate the performance of their design before committing to a full product design, it helps to reduce development costs and time to market.
