Wireless battery charger solution optimized for wearables

The combination of ST’s STWBC-WA wireless charging-transmitter controller and STWLC04 wireless battery-charger receiver enables power transfers up to 1 W over a coil of only 11 mm in diameter on the receiver side and 20 mm on the transmitter side for slimmer form factors.
Power-transfer capability can be increased to 3 W by using larger coils and a full-bridge circuit on the transmitter side.
This fully-featured chipset supports wireless-charging for Li-ion or Li-polymer battery chemistries and provides safety mechanisms such as Foreign-Object Detection (FOD).
You can jump-start your wireless-charging design with the plug-and-play STEVAL-ISB038V1 evaluation kit which includes receiver and transmitter boards as well as a GUI to monitor system behavior and fine-tune parameters.

New multi-mode Qi/AirFuel Inductive wireless power Rx/Tx solution

The STWLC33 is a highly-integrated wireless power receiver with transmitter functions targeting 15 W applications. It meets all the requirements of the growing consumer market providing a flexible solution interoperable with Qi 1.2 and AirFuel Inductive charging standards.

It provides state-of-the art performance in terms of efficiency, safety and flexibility. The STWLC33 allows the fast charging of mobile devices and can be used as a transmitter with power transfers up to 5 W towards wearable accessories.
