The MCP73213 OVP Dual-Cell Li-Ion Battery Charger Evaluation Board is fully 
assembled and tested for charging a single-cell Li-Ion or Li-Polymer battery.

POWERING THE MCP73213 OVP DUAL-CELL LI-ION BATTERY 
CHARGER EVALUATION BOARD

1.

Connect the positive battery terminal to V

BAT+

 and negative battery terminal to 

V

BAT-

.

2.

Connect the 9V DC power supply Negative Terminal to V

SS

.

3.

Connect the 9V DC power supply Positive Terminal to V

DD

.

4.

It should initiate the battery charging cycle when the power source is present and 
V

BAT

 is below recharge threshold. For example, When V

REG

 is 8.4V, V

BAT

 needs 

to be lower than 7.98V to initiate the charge cycle.

5.

The charging status table is available on Table 2-2.

6.

The fast charge current is preset at 500 mA and can be increased to 1A by 
connecting PROG via to ground.

Note: The Li-Ion battery pack can be replaced with test circuit or electronic load 

that can sink current with DC power supply. Refer to Figure 2-3.

Note: Fast Charge Current can be programmed with various resistors based on 

Figure 2-2 and Table 2-1.
