Figure 2-1 Equipment Setup

Use the following guidelines to set up and test the equipment:

1. Set power supply #1 for 30V DC, 6A 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 J3 (VBAT and PGND).
5. Connect a voltage meter across J3 (VBAT and PGND).
6. Unplug jumper JP19.
7. Set 23V at KEPCO load output. Limit KEPCO to 6A. Use load #1 to power EVM from the VOUT output.
8. Connect J5 to the EV2500. Connect J5 to the I²C PORT 2 on the EV2500.
9. Make sure the jumpers are installed as indicated in IO and Jumper Descriptions.
10. Turn on the computer and load #1. Open the bqStudio software.
    1. Select Charger and select the Next button.
       
    2. Select Charger_1_00_BQ25853.bqz on the Select a Target Page.
    3. After selecting the target device, select Field View and then select the Read Register button.

11. Set WATCHDOG and EN_CHG to disabled.
    
12. In 16 Bit Registers, set ICHG_REG to 4000mA.
13. Set EN_CHG to enabled.
14. Turn on power supply #1, measure:

    V(J1(VAC)) = 30V ± 0.5V

    I(J1(IAC)) = 3.2A ± 0.5A

    V(J3(VBAT)) = 23V ± 0.5V

    I(J3(IBAT)) = 4.0A ± 0.5A

15. Set power supply #1 for 23V, measure:

    V(J1(VAC)) = 23V ± 0.5V

    I(J1(IAC)) = 4.2A ± 0.5A

    V(J3(VBAT)) = 23V ± 0.5V

    I(J3(IBAT)) = 4.0A ± 0.5A

16. Set power supply #1 for 15V, measure:

    V(J1(VAC)) = 15V ± 0.5V

    I(J1(IAC)) = 6.4A ± 0.5A

    V(J3(VBAT)) = 23V ± 0.5V

    I(J3(IBAT)) = 4.0A ± 0.5A
