APPLICATIONS

The MCP73213 is designed to operate in conjunction

with

host

microcontroller

stand-alone

applications. The MCP73213 provides the preferred

charge algorithm for dual Lithium-Ion or Lithium-

Polymer cells Constant-current followed by Constant-

voltage. Figure 6-1 depicts a typical stand-alone

application circuit, while FiguresFigure 6-2 depict the

accompanying charge profile.
