APPLICATIONS
The MCP73827 is designed to operate in conjunction
with a host microcontroller or in stand-alone applica-
tions. The MCP73827 provides the preferred charge
algorithm for Lithium-Ion cells, controlled current fol-
lowed by constant voltage. Figure 6-1 depicts a typical
stand-alone application circuit and Figure 6-2 depicts
the accompanying charge profile.
