CHARGE COMPLETE INTERFACE
The charge complete indicator, CD10, can be utilized to
illuminate an LED when the MCP73828 is charging the
battery. When the MCP73828 is in constant voltage
mode and the charge current has diminished below
10% of I
OUT(PEAK)
, the CD10 pin will transition to a high
impedance state. A current limit resistor should be
used in series with the LED to establish a nominal LED
bias current of 10 mA. The maximum allowable sink
current of the CD10 pin is 30 mA.

PCB Layout Issues
For optimum voltage regulation, place the battery pack
as close as possible to the device’s V
OUT
and GND
pins. It is recommended to minimize voltage drops
along the high current carrying PCB traces.
If the PCB layout is used as a heatsink, adding many
vias around the external pass transistor can help con-
duct more heat to the back-plane of the PCB, thus
reducing the maximum junction temperature.
