Equipment Setup
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 GND).
3. Connect a voltage meter across J1 (VIN) and J1 (GND).
4. Connect load #1 in series with a current meter to J6 (VSYS and GND). Connect a voltage meter
across J6 (VSYS and GND). 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 GND). Connect a voltage meter
across J5 (VBAT and GND). 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 SMBus PORT 1 (BQ25710) or I
2
C PORT 2 (BQ25713)
on the EV2400. The connections are shown in
Figure 1
.
The picture shows the SMBus version EVM connection. If using the BQ25713EVM-017, move the connector to the
I
2
C port.
