APPLICATIONS
The MCP7384X is designed to operate in conjunction
with either a host microcontroller or in stand-alone
applications. The MCP7384X provides the preferred
charge algorithm for Lithium-Ion and Lithium-Polymer
cells: constant-current followed by constant-voltage.
Figure 6-1 depicts a typical stand-alone application
circuit, while Figure 6-2 depicts the accompanying
charge profile.
