Test Summary
2.2
Recommended Test Equipment
2.2.1
Power Supplies
1. Power supply #1 (PS #1) capable of supplying 6 V at 3 A is required.
2. If not using a battery as the load, then power supply #2 (PS #2) capable of supplying up to 5 V at 4 A
is required to power the circuit shown in
2.2.2
Load #1 Between BAT and GND
Testing with an actual battery is the best way to verify operation in the system. If a battery is not available,
then a circuit similar to the one shown in
then a circuit similar to the one shown in
can simulate a battery when connected to a power
supply.

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 (VM #) and two equivalent current meters (CM #) are required. The current
meters must be able to measure 4-A current.
