GETTING STARTED
The MCP73871 Evaluation Board is fully assembled and tested for charging a
single-cell Li-Ion or Li-Polymer battery with or without system load.

1. Connect the positive battery terminal to V
2. Connect the 5V - 6V DC power supply Negative Terminal to V
3. Connect the 5V - 6V DC power supply Positive Terminal to V
4. Connected positive of load to OUT (TP3) on the board and negative of load to

6. It should initiate the battery charging cycle when drive CE (TP6) high. Drive CE
7. Position the DIP Switch #2 (SW2) to “AC” allows maximum input current of 1.8A
8. Position the DIP Switch #2 (SW2) to “USB” limits the input current to meet USB

Power Input and Output Connection
POWERING THE MCP73871 EVALUATION BOARD
Fast Charge Current and Termination Current can be easily programmed
with various resistors that based on the Figure 2-1.
The Li-Ion battery pack can be replaced with test circuit or electronic load
that can sink current with DC power supply. Please refer to Figure 2-2.
