2 Test Setup and Results
2.1 Equipment
This section includes a list of supplies required to perform tests on this EVM.
1. Power Supply #1 (PS1): A power supply capable of supplying 5 V at 3 A is required. While this part can
handle larger voltage and current, it is not necessary for this procedure.
Power Supply #2 (PS2): A power supply capable of supplying 5 V at 1 A is required.
2. Loads: Load #1 (4-Quadrant Supply, Constant Voltage < 4.5 V): A "Kepco" Load, BOP, 20-5M, DC 0 to ±20
V, 0 to ±5 A (or higher)
Alternative Option: A 0–20V/0–5 A, > 30-W DC electronic load set in a constant voltage loading mode
3. Meters: (4x) "Fluke 75" multimeters, (equivalent or better).
4. No software is required to test this part.
2.2 Equipment Setup
1. Review EVM connections in Table 1-2 .
2. Set PS1 for 5-V DC, 2-A current limit and then turn off the supply.
3. Set PS2 for 3-V DC, 2-A current limit and then turn off the supply.
4. Connect the output of PS1 to J2 (VBUS and PGND) as shown in
Figure 2-1 .
5. Connect a voltage meter across TP4 (VBUS) and TP9 (PGND), or across J2.
6. Turn on Load #1, set to constant voltage mode, and output to 2.5-V. Disable Load. Connect Load to J1-3
(BAT ) and J1-1 (PGND) as shown in Figure 2-1 .
7. Connect one voltage meter across TP5 (BAT) and TP11 (PGND), or across J1-3 and J1-1 as shown in Figure
2-1 .
8. Connect one voltage meter across TP2 (PMID) and TP10 (PGND)
9. Connect the output of PS2 to TP7 (TS) and TP12 (PGND) as shown in
Figure 2-1
10.Install shunts as shown in Table 1-3 .
