STEVAL-ISB039V1

STEVAL-ISB039V1 1 W wireless charger system Tx/Rx based on STM32F0 and STWLC03 Data brief   Main features of receiver:  integrated high efficiency synchronous rectifier  integrated 1 MHz programmable buck converter with input current and input voltage regulation loops  Simplified Li-Ion/Polymer charger function RoHS compliant Description The STEVAL-ISB039V1 is a wireless battery charger evaluation kit based on the STM32F0 microcontroller for wireless battery charger transmitters and the STWLC03 integrated wireless power receiver. The STEVAL-ISB039V1 solution is primarily designed for small systems up to 1 W that can be recharged easily, and can be adjusted for 2.5 W. Features     STM32F0 for wireless power transmitter and STWLC03 for wireless power receiver 1 W output power WPC 1.1 based communication protocol Main features of transmitter:  high efficiency N-channel Half Bridge architecture with adaptive dead-time control  synchronous digital demodulation of power carrier, reduces BoM considerably  standard or enhanced power transmitter coil  coil temperature monitoring through NTC  MCU firmware open for customization  built-in USB connector for input supply voltage September 2016 For the wireless power transmitter, the firmware consists of a single STM32CubeMX platformindependent library providing a simple and easily customizable solution for the design of wireless power transmitters with proprietary features. The STWLC03 receiver can deliver the output power in two modes: as a power supply with configured output voltage or as a simple CC-CV battery charger with configurable charging current, charging voltage and termination current. The I²C interface allows the customization of parameters in the device and and the storage of configurations in the embedded non-volatile memory.
