2 Test Summary
2.1 Equipment
This section includes a list of supplies required for testing this EVM.
1. Power Supplies: 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.
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/0-5A >30-W DC electronic load set in a constant voltage loading mode.
Load #2 (Electronic or Resistive Load): 10 Ω , 5 W (or higher)
3. Meters: (6x) "Fluke 75" multi-meters, (equivalent or better).
Alternative Option : (4x) equivalent voltage meters and (2x) equivalent current meters. The current
meters must be capable of measuring at least 5-A.
2.2 Equipment Setup
Use the following instructions to set up the equipment:
1. Review EVM connections in Table 2 .
2. Set PS1 for 5-V DC, 3-A current limit and then turn off the supply.
3. Connect the output of PS1 in series with a current meter to J1 (VAC and GND).
4. Connect a voltage meter across TP7 (VBUS) and TP25 (PGND), or across J1.
5. Turn on Load #1, set to constant voltage mode, and output to 3.7-V. Disable Load. Connect Load in
series with a current meter (multimeter), ground side, to J5 (BATTERY and GND) as shown in
Figure 1 .
6. Connect one voltage meter across TP15 (BAT) and TP24 (PGND), or across J4-2 and J4-1 as shown
in Figure 1 .
7. Connect one voltage meter across TP14 (SYS) and TP24 (PGND), or across J2-1 and J2-2 as shown
in Figure 1 .
8. Install shunts as shown in Table 3 .
