Dual-mode (Qi + PMA) Solutions

IDT was the first in the industry to offer a dual-mode wireless power receiver IC, providing compatibility with both the Qi and PMA standards. IDT’s innovative receivers bridge the technology gap between competing transmission standards, empowering mobile device and accessory OEMs to use a single bill of materials (BOM) to support both standards. The dual-mode wireless power receivers automatically switch between Qi and PMA protocols and negotiate the power exchange without user supervision. This simplifies the system architecture and ensures seamless operation during everyday use. The devices deliver 5 W in Qi and PMA modes in accordance with those standards.

Qi-compliant Wireless Power Receiver ICs

IDT’s Qi-compliant wireless power receiver IC s enable OEMs to develop portable devices that are fully compatible with any Qi-compliant charging base. The devices function by converting an AC power signal from a resonant tank into a regulated 5 V output voltage, which can be used to supply power to the mobile system. For the best efficiency, IDT offers compact solutions with an integrated synchronous full bridge rectifier, high-efficiency buck converter, and control circuits. Ultra-compact wireless power receiver ICs swap out the buck converter for a 5 V LDO to minimize PCB area requirements. All devices provide output power up to 5 watts in accordance with the WPC “Qi” specification.

PMA-compliant Wireless Power Receiver ICs

IDT extends its leading technology into PMA-compliant wireless power receiver ICs. Similar to the Qi-compliant devices, the PMA-compliant devices function by converting an AC power signal from a resonant tank into a regulated 5 V output voltage. IDT’s PMA-compliant devices offer options for DC modulation connections to facilitate low-cost, minimized BOM applications. The devices include the control circuitry required to modulate the load to transmit PMA-compliant message packets to the base station.

Airfuel-compliant Solutions

IDT is working cooperatively with prominent industry players to develop next-generation solutions that are Airfuel compliant. Currently, these solutions are only available to a limited group of qualified customers. Please contact your local IDT sales representative for more information about Airfuel-compliant wireless power receiver ICs.

About Wireless Power Receivers
At a high level, wireless power receiver ICs are intelligent devices used to take an incoming AC supply from the receiving coil and convert it into a well-regulated DC supply voltage for use in the system. Wireless power receiver ICs will generally integrate a full-bridge rectifier and linear or switching voltage regulator, along with all the necessary communication and control circuitry necessary to comply with the wireless power standard.
