2.4.4 Device Support Options
The MCP7382X Evaluation Board provides evaluation of three Li-Ion battery chargers:
MCP73826, MCP73827, or MCP73828. Device selection is performed by placing
shunts on JP4 and JP5 as indicated in the table below. JP4 determines which device
is controlling the pass transistor. JP5 is used to enable the appropriate device.

2.4.5 Microcontroller Option
JP6 provides an easily accessible location for interface to a host microcontroller. The
host microcontroller can be used to disable the charger, monitor charge status, monitor
the charge profile, or terminate a charge.
A proto-typing area is provided for generation of a self-contained microcontroller solu-
tion.
2.4.6 Output Voltage Options
The MCP7382X Evaluation Board is provided with a constant voltage mode output
voltage of 4.2V. Evaluation with a constant voltage mode output voltage of 4.1V can be
achieved by replacing U1, U2, or U3 with the appropriate device. Refer to the
appropriate data sheets for device ordering information.
