Additionally, the 5W1COILTX reference
design uses Freescale’s innovative wireless
charging transmit controller to perform digital
demodulation on incoming communication
from the receiver. This unique feature provides
a major reduction in BOM costs and the
added benefit of a reduced PCB footprint.
Another feature is robust foreign object
detection (FOD) algorithm. This feature detects
metallic objects such as aluminum or steel
objects that may be present in the charging
environment. Freescale foreign object
detection algorithms easily meet and exceed
the latest standards within industry.
Ultimately, the 5W1COILTX reference design
is a complete system solution, containing all
of the hardware and software components
necessary to quickly implement a single-
coil charger solution. Freescale provides all
of the necessary hardware documentation,
including schematics, layout and assembly
files as well as a complete BOM. A firmware
library is provided which contains all of the
necessary wireless charging control blocks.
Access to the library is provided via an API
which lets users interact with parameters
and settings contained in the firmware,
providing maximum control to the engineer.
Customers can choose to use a ready-to-use
binary file provided by Freescale or to take a
more developmental approach and build an
application around the firmware library.
