Qi Wireless Power Transfer

State-of-the-art Qi Inductive Wireless

Eggtronic develops state-of-the-art Qi wireless transmitters and receivers based on Eggtronic TX and RX ICs, and is a member of the Wireless Power Consortium (WPC).

The company offers automotive, industrial and consumer Qi solutions and ICs, which are compatible with the latest version of the standard (1.3) and ensure backward compatibility with previous releases (1.2).

Eggtronic Qi designs support power ratings from 5W to 15W, are compatible with the EPP protocol, and include data-over-power solutions to transfer both power and user data (CAN / LIN / I2C / SPI / UART) through the inductive coil.

Single or multiple coil solutions are available.

Safe charging is always guaranteed thanks to a variety of protection and security features including FOD (Foreign Object Detection) and recognition of NFC/RFID cards such as credit cards or transportation cards.
