Use the following guidelines to set up the equipment:

1. Set power supply #1 for 10-V DC, 5-A current limit and then turn off the supply.
2. Connect the output of power supply #1 in series with a current meter to J1 (VIN and PGND).
3. Connect a voltage meter across J1 (VIN) and J1 (PGND).
4. Connect load #1 in series with a current meter to J6 (VSYS and PGND). Connect a voltage meter across J6 (VSYS and PGND). Set 1 A at the constant current mode. Turn off load #1.
5. Connect Load #2 in series with a current meter to J5 (VBAT and PGND). Connect a voltage meter across J5 (VBAT and PGND). Set 7 V at KEPCO load output. Turn off Load #2.
   Note:

   Add a 47-µF capacitor on the BAT pin when testing without real battery.

6. Connect J3 to the EV2400. Connect J3 to the I²C PORT 2 on the EV2400. The connections are shown in Figure 2-1.
   

   The picture shows the SMBus version EVM connection. For I²C version, move the connector to the I²C port.

7. Install jumpers using the “factory settings” from Table 1-2.

   After completing these steps, the test setup for BMS051 is as shown in Figure 2-2.

8. Turn on the computer and power supply #1. Open the BQstudio software.
   1. Select Charger and click the Next button.
      
   2. Select “Charger_1_00_BQ2573x.bqz” on the Select a Target Page.
   3. After selecting the target device, change “update mode” from “immediate” to “manual”, click “Read Register” and the following interface is presented.
