Texas Instruments’ bq501210 wireless power transmitter is designed for personal electronics, medical, and space-constrained industrial applications. The bq501210 enables 84% system efficiency while using less thermal dissipation. Industrial end equipment such as electronic point-of-sale (POS) devices and handheld medical equipment reap the benefits of 15 W wireless power. Its fixed-frequency operation helps improve efficiency as well as reduce electromagnetic interference (EMI). It also features fast-charge negotiation with mobile devices enables the transfer of up to 10 W to compatible receivers. The high-voltage dedicated charging port (HVDCP) protocol negotiates with capable ac/dc wall adapters to adjust the input voltage. The rail control output provides power to deliver a full 15 W with inputs between 15 and 19 V, and enables lower power operation, such as 5 W, with inputs as low as 5 V.
