Introduction
This demonstration board allows the easy measurement of STCC50x1 parameters and the
evaluation of all its functions and operating modes.
Note:
The STCC2540 demonstration board is exactly the same, just assembled with the
STCC2540 instead of the STCC50x1 device. For details, please see

By default, the board is powered from a USB host (notebook, PC, docking station, etc.) through the J2 USB connector. No external power supply is necessary. In this mode, evaluation of all STCC50x1 device features is possible with the following limitation: Maximum charging current is limited by the USB host capabilities (typically 500 mA to 2000 mA). -
