Power Supply
The KIT_XMC4400_DC_V1 board is designed with two galvanically isolated supply domains. On the left side,
there is the debug domain, which contains a XMC4200 MCU as on-board debug controller (OBD) as well as
level shifters to a 5V debug interface like the drive monitor USB stick (KIT_DRIVEMONI_USB_V2). The debug
domain can be powered via the USB plug (5V) as well as the CAN connector or the Infineon debug connector.
On the middle to the right side there is the power GND supply domain, which provides the power supply for the
MCU and the peripheral components. This supply domain is usually powered from the power board connector. If
the current provided by the power board is not sufficient, then the multi feedback interface connectors can be
used as well.
For both supply domains a separate power indicating LED is available.
The typical current drawn by the drive card at the power GND domain is about 180 mA.
To indicate the power status of the KIT_XMC4400_DC_V1 board two power indicating
LED‟s are provided on
board (see Figure 3
). The LED will be “ON” when the corresponding power rail is powered.
