Space and complexity are two key concerns in portable electronic design. The highly
integrated MCP73871 device has overcome the hurdles by including the required ele-
ments to meet the design challenges when developing new Li-Ion / Li-Polymer battery
powered products.
The MCP73871 requires minimum external components to power the system load and
charge single cell Li-Ion batteries independently. When input power is absent or
insufficient, the Li-Ion battery becomes the primary power source or in help mode to
support the required system load current. The MCP73871 Evaluation Board is
developed to assist product designers in reducing product design cycle and time by
utilizing Microchip’s favorite stand-alone Li-Ion battery charger and system load
sharing management controller.
