Test Summary
Figure 2. BAT Load (PR1010) Schematic
2.2.3 Load #2 Between SYS and GND
Although not required, a resistive load capable of sinking up to 3 A can be used.
2.2.4 Meters
Four equivalent voltage meters (VMx) and two equivalent current meters (CMx) are required. The current
meters must be able to measure at least 3-A current.
2.3 Recommended Test Equipment Setup
1. For all power connections, use short, twisted-pair wires of appropriate gauge wire for the amount of the
current.
2. Set Power Supply number 1 for 6 V ± 100 mV, 3-A current limit, and then turn off supply.
3. If BAT_Load (PR1010) as shown in Figure 2 is used, connect Power Supply number 2 (PS2) set to
approximately 3.6 V to the input side (PS2+/-) of BAT_Load (PR1010), then turn off PS2.
4. Connect the output side of the battery or BAT_Load (PR1010) in series with current meter (multimeter)
number 2 (CM2) to J2 and J6 or J3 (BAT, GND). Ensure that a voltage meter is connected across J2
or TP3 and J6 or TP9 (BAT, GND).
5. Connect VM3 across J5 or TP4 and J9 (SYS, GND).
6. Connect VM4 across J13 and J15 (DRV, GND).
7. Ensure jumpers are at the default factory settings per Section 1.6
8. After the preceding steps are accomplished, the test setup for HPA741 is as shown in Figure 3
