STMicroelectronics STWBC-EP | Demoboard STEVAL - ISB044V1
Qi MP-A10 15 W wireless charger TX evaluation kit based on STWBC-EP
Overview
| Topology | Wireless Power Transfer |
Description
The STEVAL-ISB044V1 evaluation kit has been designed for devices, such as smartphones or tablets, requiring high power levels. It supports wireless battery charging up to 15 W. 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 STEVALISB044V1 available on www.st.com which give runtime information, such as the power delivered, the regulation error or the protocol status as well as parameter tuning.
Features
- STWBC-EP digital controller
- 15 W output power
- Qi MP-A10 reference design
- WPC Qi1.2.3 standard compliant
- Robust demodulation algorithm, with triplepath (V, I, f)
- Foreign object detection (FOD)
- Accurate power control
- Active presence detection
- UART protocol to control and monitor thesystem
- Complete reference design (evaluationboard, IC, firmware and tools)
- 2-layer PCB for easy design
- Flash memory-based
- RoHS compliant
