1 STEVAL-ISB0V Data brief Qi MP-A0 W wireless charger TX evaluation kit based on STWBC-EP Features STWBC-EP digital controller W output power Qi MP-A0 reference design WPC Qi.. standard compliant Robust demodulation algorithm, with triple path (V, I, f) Foreign object detection (FOD) Accurate power control Active presence detection UART protocol to control and monitor the system Complete reference design (evaluation board, IC, firmware and tools) -layer PCB for easy design Flash memory-based RoHS compliant Description The STEVAL-ISB0V evaluation kit has been designed for devices, such as smartphones or tablets, requiring high power levels. It supports wireless battery charging up to W. Summary table Qi MP-A0 W wireless charger TX evaluation kit based on STWBC-EP Digital controller for wireless battery charger transmitters (WBC) in W medium power applications STEVAL-ISB0V STWBC-EP The embedded STWBC-EP digital controller transmitter is based on a cost-effective half-bridge topology providing external interfaces via UART and I²C. The kit also includes STWBC-EP firmware, a graphical interface for debug, schematics, layout files and bill of materials. There are specific tools for the STEVAL-ISB0V available on which give runtime information, such as the power delivered, the regulation error or the protocol status as well as parameter tuning.
