Description
The STEVAL-ISB038V1R is based on the STWLC04 integrated wireless power receiver, suitable for wearable applications. The STWLC04 focuses on the 1 W protocol based on Qi; digital control and precise analog control loops assure stable operation. The STWLC04 can deliver the output power in two modes: as a power supply with configured output voltage, as a simple CC/CV battery charger with configurable charging current, charging voltage and termination current. The STEVAL-ISB038V1R package includes the wireless charger receiver board; the PC GUI application software for users to configure the most common parameters; the USB-to-I²C converter board for connection between the PC and the wireless charger receiver board.
