other set-up steps are complete.
1. Place a jumper on JP4 to select the appropriate device for evaluation.
2. Place a jumper on JP5 to enable the appropriate device for evaluation.
3. Connect an external bench supply or voltage regulated wall cube to JP1.
Observe correct polarity of connection.
4. Connect a single cell Li-Ion battery pack to JP2. Observe correct polarity of
connection.
5. For MCP73828 evaluation, connect external battery pack thermistor to JP3.
6. Turn-on bench supply or plug-in wall cube.
7. For MCP73827 evaluation, LED D3 shall be turned off when the charge cycle
transitions from controlled current mode to constant voltage mode charge.
8. For MCP73828 evaluation, LED D2 shall illuminate when the battery pack is at
full charge.
