2.2.4Meters
Four Fluke 75 multimeters (equivalent or better)
Or:
Three equivalent voltage meters and one equivalent current meter
The current meter must be capable of measuring
2.2.5Wire Gauge
All wires connected to the EVM input power supply and output load must be at least AWG 22. The maximum current is up to 1 A.
2.3Equipment Setup
1.Set PS 1 for 0 V ±100 mVdc, 2 ± 0.1 A current limit, and then disable the output.
2.Connect the output of PS 1 to J1 (DC+,
3.Connect a voltage meter across J1 (DC+,
4.Connect the output of load 1 in series with a current meter (multimeter) to J2 (CHGIN) and J3 (GND). Turn on the power of load 1. Set the load current to 1.5 A ±50 mA, but disable the output.
5.Connect the output of load 2 in series with a current meter (multimeter) to J4 (BAT+,
6.Connect a voltage meter across J4 (BAT+,
7.Set the voltage of load 2 to 3.6 V ±0.1 V, and disable output of load 2.
8.JP1: ON, JP2 (BATEN, GND): ON, JP3: OFF, JP4: ON, JP5: ON, JP6: ON, JP7: OFF.
After the preceding steps have been taken, the test setup for HPA666 (bq24351 DSG EVM) appears as is shown in Figure 1.
