Equipment Setup
1. Set PS#1 for 5 V
±
100 mVdc, 1.7
±
0.1-A current limit and then turn off supply. Connect the output of
PS#1 to J1 (DC+, DC
–
).
2. If simulated battery circuit is used in place of a battery, set the PS#2 for 3.5 V
±
100 mVdc, 1.8
±
0.1-A
current limit and then turn off supply.
3. Connect the battery (discharged to ~3.1 V) or simulated battery load to J2 as shown in
. If
simulated load is used, connect the output of PS#2 (+ lead) to the anode of the simulated load and
return to ground (DC
–
).
4. Connect the system load to J3 (DCOUT, GND).
5. Connect digital multimeter 1 (DMM#1) across J2 (BAT+, GND), and set to measure DCV (5-V range).
6. Connect DMM#2 across BAT
–
Sense Resistor (0.1
Ω
,
≥
2 W), and set to measure mVdc (
<
300-mV
range).
7. Connect DMM#3 across the J3 (DCOUT, GND), and set to measure DCV (5-V range).
8. Connect J4 to HPA172 kit by 10-pin ribbon cable. Connect the USB port of the HPA172 kit to the USB
port of the computer. The connections are shown in
Figure 1. Connections of HPA172 Kit
9. Install jumpers JMP1-2/3 (CD, GND); JMP2-1/2 (PSEL, HI); JMP3-1/2 (LED); JMP4-2/3 (TS_4.7k,
GND)
10. Connect scope to TP9 and set to 2 V/div and 200 ns/div (not shown in setup).
