Tri-mode receiver supports magnetic resonance
Integrated Device Technology (IDT) 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 utilising 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, 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 5W output power, and is available to select customers, while the P9762 variant offers 10W 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 16W.
IDT’s magnetic induction products have been deployed in more than 70m devices, from leading smartphones to wearables to furniture. The company has also been developing magnetic resonance technology for years, with longstanding partnerships. In addition, the company last year introduced wireless power reference kit program, providing an easy path for engineers without wireless power expertise to integrate the capabilities into designs.
