are low-powered products such as wearables, toothbrushes, headphones,
hearing aids, smart glasses, smartwatches, fitness bands, smart clothing, smart
sports equipment, smart stylus, and IoT.
An XMC based 2.5W low-power solution, called “The Hydra”, is the industry’s lowest
cost resonant wireless charger. By using a frequency of 6.78MHz, very small coils
can be employed in a variety of form factors, with no regard to nearby metallic objects.
These benefits make the technology ideal for charging wearables, headphones,
smart clothing and other connected IoT applications. The transmitter and receiver
solution use resonant technology and supports one-to-one and multi-device charging.
The input power supply is 5V - 19V.
“The Valkyrie” is a certified Qi transmitter that supports the latest 15W power
transfer specification for all fast charge smart phones. The solution provides an easyto
use wireless power design kit and enables high efficiency (>80% tested) combined
with class leading FOD. In addition, the solution’s low component count enables
designs with reduced system costs (figure 4). It achieves charging rates nearly equivalent
to wired charging and supports custom charging profiles and industry standards
on the same hardware.
Infineon also provides a 15W
3-coil reference design for automotive
in-cabin wireless charging
(figure 5), called “The Beast”,
which is both Qi certified and
automotive qualified. In an industry
first, the reference design has also
been certified CISPR-25 Class 4,
for EMI performance unmatched
in the market. The AURIX-based
design supports wireless charging,
CAN and external NFC-interface
with a single CPU. Built-in security
functionality (HSM) meets latest
automotive requirements. The solution
is highly scalable and flexible
and provides a very robust FOD.

transmitter (The Valkyrie) with low component
count based on an XMC microcontroller

The AURIX can also support the charging of two devices using a single controller,
thereby reducing system cost and size.
For applications
such as 5G
Customer Premises
Equipment (CPE),
outdoor security
cameras, telecom
infrastructure and
factory automation,
a solution
called “The Gorgon”
provides high
efficiency wireless
power transmission.

based on the powerful AURIX microcontroller.
A proprietary inductive transmitter and receiver solution, the system can continuously
power a device up to 30W through 30mm of glass (including low-E coated glass) or
other non-metallic building material.
“The Minotaur” is the only 45W complete wireless charging system for next-generation
tablets and laptop computers. The solution provides high efficiency (95% tested)
charging that is easy to integrate with a reduced thermal impact (figure 6). The solution
extends the existing smartphone charging ecosystem, allowing true backward
and forward interoperability for users to take advantage of the growing Qi infrastruc-
