2 Test Summary
2.1 Equipment
This section includes a list of supplies required for testing this EVM.
• Power supply: Power supply #1 (PS#1): A power supply capable of supplying 5 V at 1 A is required.
While this part can handle larger voltage and current, it is not necessary for this procedure.
• Load #1:
– 4-quadrant supply, constant voltage < 4.5 V, A 0 – 20 V, 0 – 5 A, > 30-W system, DC electronic
load and setting as constant voltage load mode
or
– Kepco load: BOP 20 – 5M, DC 0 to ±20 V, 0 to ±5 A (or higher).
• Load #2: Use with Boost Mode, PMID to GND load, 10 Ω , 5 W or greater.
• Meters:
– Six Fluke 75 multimeters, (equivalent or better)
or
– Four equivalent voltage meters and two equivalent current meters. The current meters must be
capable of measuring 5-A current.
• Computer: A computer with at least one USB port and a USB cable. The bq25600DEVM evaluation
software must be properly installed.
• USB-to-GPIO Communication Kit: EV2300/EV2400 USB-based PC interface board.
• Software: Download bqStudio from www.ti.com .
1. Double click the Battery Management Studio-1.3.20_Build2-Setup installation file, follow the
installation steps. The software supports the Microsoft® Windows® XP and Windows 7 operating
systems.
2. Copy the bq25600 bqz file to C:\ti\BatteryManagementStudio\config
2.2 Equipment Setup
Use the following instructions to set up the equipment:
1. Set PS#1 for 5-V DC, 1-A current limit and then turn off the supply.
2. Connect the output of PS#1 in series with a current meter (multimeter) to J1 (VBUS and GND).
3. Connect a voltage meter across TP1 (VBUS) and TP18 (GND).
4. Turn on the load, set it to constant voltage mode and set the output to 2.5 V.
5. Turn off (disable) the load.
6. Connect the load to J5 (BAT and GND), as shown in Figure 2 .
7. Connect one voltage meter across TP9 (BAT) and TP20 (GND) to measure the battery voltage and
another voltage meter across TP28 and TP29 to measure the battery current sensing resistor voltage.
The sensing resistor is 10 m
Ω . It is also OK to use the optional current meter in series to measure the
battery current.
8. Connect the EV2300/2400 USB interface board to the computer with a USB cable and from the I2C
port to J8 with the 4-pin cable. The connections are shown in Figure 1 .
