STEVAL-ISB039V1T STMicroelectronics

ST EVAL -I SB 039V1T 1 W Wireless power transmitter based on STM32F0 Data brief Description The STEVAL-ISB039V1T is a wireless power transmitter based on the STM32F0 microcontroller and primarily designed for small systems requiring easy recharging up to 1 W this solution can be adjusted up to 2.5 W. The wireless power transmitter consistes of a power conversion unit which generates the alternating electromagnetic field transmitted between two planar coils. The built-in USB connector supplies the wireless power transmitter and the SWD debugger connector allows the monitoring of system parameters such as battery charging level, power transmitted, efficiency, working frequency and power receiver identification. The firmware is a single STM32CubeMX platform-independent library providing a simple and easy to customize solution for the design of wireless power transmitters with proprietary features. Features Core: ARM 32-bit Cortex -M0 with32 Kbytes Flash, 48 MHz CPU 1 W output power WPC 1.1 based communication protocol High efficiency N-channel Half Bridge architecture with adaptive dead-time control Synchronous digital demodulation of power carrier, significantly reduces the BOM Standard or enhanced power transmitter coil Coil temperature monitoring through NTC MCU firmware available open for customization Built-in USB connector for input supply voltage RoHS compliant August 2016 DocID029612 Rev 1 1/6 www.st.com For further information contact your local STMicroelectronics sales office Schematic diagrams STEVAL-ISB039V1T 1 Schematic diagrams Figure 1: STEVAL-ISB039V1T circuit schematic (1 of 3) GSPG0108161455SG 2/6 DocID029612 Rev 1
