GETTING STARTED
The MCP73833 Li-Ion Battery Charger Evaluation Board has one circuit fully
assembled and tested for charging single cell, Li-Ion/Li-Polymer battery packs. The
board provides the appropriate charge algorithm for simple, stand-alone operation.
The board requires the use of an external input voltage source (5V ±10%,
recommended) and external load (battery pack or simulated battery load).
