Description Current Consumption
The Current Consumption of the device is characterizing the current the device needs to operate. The Quiescent
Current is describing the Current Consumption in a very low load condition (e.g. the supplied microcontroller is in
sleep mode). The IFX54211MB V33 has an Enable functionality to shutdown the device, in case it is not needed.
During shutdown the device has a very low Current Consumption. The Current Consumption of the device is
defined as the delta between I_IN and I_OUT and thus can be determined by measuring the current flowing out of the
GND Pin when subtracting I_EN.
