3.3 Power
The MGM13S has an Energy Management Unit (EMU) and efficient integrated regulators to generate internal supply voltages. Only a
single external supply voltage is required, from which all internal voltages are created. An integrated DC-DC buck regulator is utilized to
further reduce the current consumption.
Figure 3.2 Power Supply Configuration for MGM13S02xxx Devices on page 9
and
3.3 Power Supply Configuration for MGM13S12xxx Devices on page 9
show how the external and internal supplies of the module
are connected for different part numbers.
