Texas Instruments Inc. (TI) has announced plans to create multi-mode wireless power ICs for smartphones and other portable electronics. The company also said it will develop products that support the Alliance for Wireless Power (A4WP) magnetic resonance specification. A4WP is a group of electronics companies that include Samsung, Qualcomm and others, focused on advancing spatial freedom in wireless power.

TI will continue to develop bqTESLA wireless power receiver and transmitter ICs that comply with existing and future versions of the Wireless Power Consortium (WPC) Qi standard. In addition, TI plans to create products that support both Qi and the Power Matters Alliance (PMA) wireless charging specification. The first multi-mode solutions are expected later this year.

TI's advanced receiver and transmitter ICs include the recently announced bq51050B single-chip wireless power receiver with integrated charger and the bq500410A 3-coil transmitter with spatial freedom.
