bq2512x Evaluation Module
2.1.3 Meters
Three voltage meters and two current meters. The current meters must be able to measure at least 0.5-A
current.
2.1.4 Tool/Software GUI (Optional)
The following optional items can be used for testing:
1. EV2400 Communication Interface Board
2. bqStudio Software GUI
2.2 Recommended Test Equipment Setup
The following guidelines provide the recommended test equipment setup:
1. Set power supply #1 (PS#1) for 5 V ±100 mV DC, 1-A current limit and then turn off supply. Set power
supply #2 (PS#2) for 3.5 V and then turn off supply.
2. Connect the positive output of PS#1 through a current meter (CM#2) to IN (J2) and negative output to
GND (J34).
3. Connect a voltage meter (VM#1) across J2 and J34.
4. Connect the PR1010 BAT+ terminal of PR1010 in series with a current meter (CM#1) to BAT (J29).
Connect PR1010 BAT – to GND (J34). Connect the P/S+ and P/S return side of PR1010 to PS#2, set
the voltage to 3.5 V ±50 mV, then disable PS#2.
5. Connect a voltage meter (VM#2) across BAT (J29) and GND (J34).
6. Connect a DMM (VM#3) across SYS (SYS_S+ of J27) and GND (GND_S– of J27).
7. Configure jumpers as shown in Table 4 .
After the preceding steps are accomplished, the test setup for PWR731 is as shown in Figure 3 . The
setup is similar for PWR812 with the bq25121.
