Tri-mode wireless power receiver supports magnetic resonance and induction charging

February 25, 2016 // By Paul Buckley
Integrated Device Technology, Inc. has introduced 'tri-mode' wireless power receiver devices that enable AirFuel Alliance magnetic resonance and induction charging systems, as well as the Wireless Power Consortium (WPC) magnetic induction Qi technology presently deployed in many leading smartphone models.

The addition of AirFuel Alliance magnetic resonance adds greater freedom of placement and allows multiple receivers to charge from a common transmitter. This combination of technologies in a single device delivers flexibility and 'future proofing' for consumers faced with a choice of mobile devices utilizing different wireless power standards.

“IDT is the industry leader in the development of wireless power semiconductors that support multiple standards, and this time we’ve taken a big step forward by incorporating the spatial freedom capabilities of magnetic resonance,” said Dave Shepard, vice president and general manager of IDT’s Consumer Products Division. “As the leader in wireless power, we are committed to offering technology that delivers maximum flexibility to consumers. The seamless integration of the various standards in a single device addresses that commitment.”

The P9724 tri-mode device with integrated buck converter provides 5 W output power,  and is available to select customers, while the P9762 variant offers 10 W output power and is available on a pre-release basis. IDT is also previewing the Class 3 AirFuel Alliance Power Transmitter Unit (PTU) capable of output power delivery up to 16 W.
