Texas Instruments introduced its next-generation bqTESLA wireless power transmitter IC, designed to lower the transmitter bill of materials cost by integrating the transmitter and supporting components into a single chip. The bq500210 integrates the functionality required to safely and efficiently control wireless power transfer in a contactless charging base station.
By utilising Wireless Power Consortium (WPC)-compliant inductive power transfer, the transmitter provides power to Qi-compliant portable devices, such as smartphones, portable gaming systems, digital cameras and Bluetooth low energy systems, as well as medical and industrial equipment. Together with the available bq51013 or bq51011 receivers, the bq500210 offers a complete Qi-compliant wireless power solution.
Digital demodulation signal processing significantly reduces total system components from previous generation analog demodulation circuitry. An integrated real-time efficiency analyser maximises power transfer efficiency, reduces power consumption, and protects the transmitter and receiver from excessive power loss and heat. Parasitic metal object detection (PMOD) provides protection from power transfer to metal objects, overheating and power loss. Overload and over-temperature protection ensures safe and reliable operation.
