Wireless power transfer technology continues to grow

In addition to enabling systems to be waterproof so they are easier to clean and sterilise, new applications such as medical equipment and drones are beginning to emerge.

The STWBC family of transmitter ICs performs all the functions for transmitter control, ensuring compliancy with the leading standards in the market and providing customers with a turnkey Qi-certified solution, for a fast go-to-market strategy, or with an environment to build personalised solutions.

Efficient power transfer is enhanced by a smart standby state while waiting for a receiver, which guarantees a power consumption as low as 3mW while maintaining the Foreign Object Detection (FOD) function active for maximum safety.

The STWLC family of receiver ICs meets all the requirements of the growing consumer market providing a flexible solution interoperable with Qi and AirFuel Inductive charging standards. STWLC family is able to efficiently charge any battery chemistry like single-cell Li-Polymer/ Li-Ion and support direct charging, transmitter functions is also integrated.

An embedded 32-bit microcontroller and integrated non-volatile memory allow a very wide range of customisation. All this come in a minuscule footprint chip-scale package, suitable for space-constrained portable applications.

To support customers in building their applications and minimise the time-to-market, a complete development ecosystem is available including certified reference design boards, API libraries and documentation to customise software, and graphical user interfaces to access to real time data and configurable parameters.
