3.2.2.1 DC Distribution Major Components
The controller's DC section is made up of MAKO and external regulators. This section will give an
overview of the schematics and circuitry that makes up the major supplies of the DC architecture.
3.2.2.1.1 MAKO
MAKO (U6501) is a custom power management IC manufactured by Atmel. MAKO controls almost
all of the LDO supplies to the controller.
Table 3-5
illustrates all of MAKO's LDO and the supplies that
feed them.
Figure 3-16
shows all of MAKO's LDOs their voltage level and components that can be
accessed to verify operation.
Figure 3-16
also shows where the battery supply and on off switch can
be accessed. MAKO is also responsible for the timing sequence for the enabling of the regulators
which is discussed further in
section 3.1.3.7.1
and
section 3.1.3.7.3
on
pages
3-15
and
3-16
.
