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.
