STMicroelectronics the plug and play wireless charger development kit (steval-isb045v1) allows users to quickly develop up to 2.5w ultra-small chargers with space-saving 20mm diameter coils to charge small iot and wearable devices such as smartwatch sports equipment or medical care equipment.
This development kit includes a STWBC - WA based wireless charging emission charging base unit of the controller, on the base is a transmitter circuit board and a connected and can be used at any time of 20 mm coil suite use method is simple, use STSW STWBCGUI computer software can be configured STWBC - WA controller and monitor runtime information (for example: the quality of power supply power bridge frequency demodulation and protocol state) the suite also includes a used to run the GUI encryption dog.
The supporting ecosystem consists of a certified reference board software and detailed documentation to help developers quickly roll out the smallest and best-performing chargers in the rapidly growing smart Internet of things and wearables new market.
STWBC - WA controller chip integrates drive native support for antenna power full bridge or half bridge topology and half bridge topology can be smaller in diameter coil to provide the highest 1 w power charging, the charger design smaller the chip supports all standard wireless charging function, including external foreign body detection (FOD) and active safety charging function, and can through digital feedback to adjust the transmission power, under the condition of any load maintain the best energy efficiency two alternative firmware allows the user to choose quick one-stop integrated solution, or use API to access the ADC UARTPeripheral on GPIO and other chips, according to their own requirements configuration application.
Steval-isb045v1 development kit is now on the market stwbc-wa launch controller IC has been put into production.
