WPC compliant wireless charging IC in 7x7 mm package

Texas Instruments Incorporated (TI) has introduced its next-generation bqTESLA wireless power transmitter integrated circuit (IC). The bq500210 is 50-percent smaller than TI's previous transmitter chip, minimizing the impact to portable power designs and solution size, claims TI.

According to TI, the small, intelligent IC integrates all the functionality required to safely and efficiently control wireless power transfer in a contactless charging base station, by utilizing Wireless Power Consortium (WPC) compliant inductive power transfer, the transmitter provides power to Qi-compliant portable devices, such as smart phones, portable gaming systems, digital cameras and Bluetooth low energy systems, as well as medical and industrial equipment.

Key features and benefits of the bq500210 include:
Single-chip wireless power transfer controller compliant to WPC Qi-compliant specification 102.
Real-time efficiency analyzer maximizes power transfer efficiency, reduces power consumption, and protects itself and the receiver from excessive power loss and heat.
Closed-loop power transfer control via frequency modulation for comprehensive system-level power transfer management.
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.
Small 7-mm x 7-mm, 48-pin QFN package minimizes impact to end equipment designs.
