2 Test Summary
This section describes the test configuration of the bq2512xEVM evaluation module for bench evaluation.
2.1 Recommended Test Equipment
2.1.1 Power Supplies
1. Power Supply #1 (PS#1): a power supply capable of supplying 5 V at 1 A is required.
2. Power Supply #2 (PS#2): a power supply capable of supplying 5 V at 1 A is required.
2.1.2 Load
Testing with an actual battery is the best way to verify operation in the system. If a battery is unavailable,
then a source meter like a Keithley 2420, capable of both sourcing and sinking current, or a circuit similar
to the one shown in
Figure 2 can simulate a battery when connected to PS#2.
