Recommended Test Equipment
4.1.1
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 5 A
is required to power the circuit shown in
4.1.2
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
supply.
