　　A brief discussion on ti wireless charging chips and solutions

　　The development of wireless charging technology has been in-depth research and application in the electronic field so far. Although it has not been widely popularized, it has achieved good results in the development of consumer electronics. Mobile phone manufacturers have also added this innovative advanced charging technology to their flagship phones. Mobile phones such as Samsung S6, Sony Xperia Z3+, Google Nexus6, and Nokia Lumia 930 all use wireless charging technology.

　　Wireless power can bring real system benefits in applications, such as removing connectors to increase reliability and durability, making systems waterproof for easier cleaning, and providing a better user experience through increased convenience. Other applications can benefit from the increased security that comes with removing contact points, as well as the ability to deliver power and even data over challenging interfaces. TI is a proven industry leader in wireless power, offering a broad range of solutions to support wearables, smartphones, automotive, industrial and medical applications.

　　Texas Instruments (TI) announced the launch of a solution that supports the industry's first fully integrated 10W wireless charging. The solution's receiver and corresponding transmitter are more efficient, helping designers of industrial, medical and personal electronics products to make their devices more efficient. Charge faster and more efficiently while getting rid of all the connectors. The bq51025 and bq500215 launched this time are currently in mass production. They not only support waterproof, dustproof and portable designs, but also charge 1-cell and 2-cell (1S and 2S) lithium-ion batteries faster without overheating. . In addition, this charging solution is compatible with any product on the market that meets the 5WQi standard, helping consumer electronics to be charged more flexibly in more places than ever before.

　　10W high-efficiency wireless charging

　　The Bq51025 receiver not only supports programmable output voltages from 4.5V to 10V, but when combined with the TIbq500215 wireless power transmitter, it can also achieve up to 84% charging efficiency at 10W power, which can significantly improve thermal performance. Measuring only 3.60 mm by 2.89 mm, this fully-featured wireless power receiver solution can be designed into a wide range of portable industrial designs, including retail scanners, handheld medical diagnostic equipment, and personal electronics such as tablets and ultrabooks. .

　　The newly released bq500215 is a dedicated fixed frequency 10W wireless power digital controller transmitter compatible with 5WQi receivers. The transmitter uses an enhanced Foreign Object Detection (FOD) method to detect foreign objects before sending any power and proactively reduce power if excessive losses are detected.

　　Main features and advantages of bq51025/bq500215:

　　●The fast charging receiver combined with the TIbq500215 controller can achieve up to 84% system efficiency at 10W power, thus enabling a fast charging experience for 1-cell and 2-cell battery-powered electronic devices;

　　●Qi-compliant communication and control ensures compatibility with any Wireless Power Alliance Qi-certified transmitter and receiver up to 5W. The wireless charging solution’s I2C communication interface not only facilitates better alignment of the receiver on the transmitter surface, but also supports the sending of proprietary data packets between the receiver and transmitter;

　　●Both devices will be compatible with TI's future mid-level power Qi standard transmitters and receivers.

　　Wireless Power Evaluation Board

　　●The bq51025EVM-649 wireless power receiver evaluation kit can help designers evaluate the operation and performance of the bq51025;

　　●The bq500215EVM-648 wireless power transmitter evaluation board provides all basic functions of a Qi standard wireless charging board. 12V input single coil transmitter helps designers speed time to market.

　　TI and wireless power

　　TI's wireless power management products support innovative and efficient wireless charging functions, not only for mobile phones, tablets and other portable electronics, but also for wireless power charging transmitters ranging from stand-alone charging pads to charging pads embedded in cars and devices. TI not only offers the broadest portfolio of power integrated circuits supporting the WpCQi standard, but is also a member of the Alliance for Wireless Power (A4Wp) and pMA.
