2.3.4 Battery Headers
Independent battery connections are provided. The battery pack positive terminal
should be connected to J5 (V
BAT
+). The battery pack’s negative terminal should be
connected to J6 (V
BAT
–).
2.3.5 Device Support Options
The MCP73855 Evaluation Board supports the MCP73855 device. The MCP73855
Evaluation Board is provided with one reference design utilizing the MCP73855.
2.3.6 Microcontroller option
Connection points provide easily accessible locations for interface to a host
microcontroller. The host microcontroller can be used to disable the charger, monitor
charge status or terminate a charge.
2.3.7 Output voltage options
The MCP73855 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 moving resistor R
4
to R
3
, or by shorting the R
3
pads.
Note: Improper connection of the battery may result in damage to the
battery and the possibility of personal injury. It is also important to
avoid shorting the battery terminals together.
