The STWBC digital controller for wireless battery charger (WBC) transmitters from STMicroelectronics offers a highly flexible solution for controlling power transfer from a WBC transmitter (Tx) to a receiver (Rx) in WBC-enabled devices that use electromagnetic induction to recharge.
As a member of the Qi Wireless Power Consortium and the PMA (Power Matters Alliance), ST ensures full compatibility with these leading wireless-charging protocols and is one of the first companies to hold certification to the newest Qi 1.1.2 A11 standard.
The STWBC performs all the essential functions for transmitter control: it is able to precisely control the amount of transmitted power to match the requirements of the receiving unit in terms of maximising the efficiency of the power transfer and minimising any increase in operating temperature.
Featuring native support for half-bridge and full-bridge topologies, the device operates from 5 V and is capable of power levels up to 5 W. The digital feedback between Tx and Rx units also allows the detection of metal objects close to the receiver (foreign object detection) that could result in potential hazards, enabling the STWBC to stop power transmission when such objects are detected.
Firmware options give customers the ability to personalise their end product without the need of external microcontrollers. These options include a turnkey, Qi 1.1.2 A11 certified solution (reference design board STEVAL-ISB027V1), fully interoperable with Qi-enabled mobile phones; and API (application programming interface) access to customise the underlying firmware, for example modifying the behaviour of the LEDs or GPIOs in response to the receiver behaviour and supporting I²C and UART communication within a network.
The device is offered together with a complete ecosystem to support customers in building their applications, including the Qi 1.1.2 A11-certified reference design board (STEVAL-ISB027V1), API libraries and documentation to develop software customisations, as well as a comprehensive graphical user interface to monitor real-time performance and diagnostics. Housed in a VFQFPN32 package, the STWBC is available in full production.
