GETTING STARTED
The MCP73831 Evaluation Boards are fully assembled and tested for charging
single-cell, Li-Ion/Li-Polymer battery packs. The boards provide the appropriate charge
algorithm for simple, stand-alone operation.
The boards require the use of an external input voltage source (5V ±10%,
recommended) and external load (battery pack or simulated battery load).

evaluate the charge management circuit is to use a single-cell Li-Ion battery
pack, or the recommended simulated battery load. Refer to Figure 2-2.
