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.
For the wireless power transmitter, the firmware
consists of a single STM32CubeMX platform-
independent 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.
