Test Summary
2.1
Equipment
This section includes a list of supplies required to perform tests on this EVM.
1.
Power supply (PS#1)
: The power supply must be capable of supplying up to 6.5 V at 3.3 A. While this
part can handle larger voltage and current, it is not necessary for this procedure.
2.
Battery simulator (BS#1, BS#2)
: Four-quadrant supply set to constant voltage
≤
9.2 V
Example: Kepco Bipolar Power Supply: BOP 20–5M, DC 0 to ±20 V, 0 to ±5 A (or higher) and Keithley
2420 Sourcemeter
3.
Load #1:
Electronic or resistive load capable of sinking up to 3 A at 9.2 V
4.
Meters:
Six Fluke 75 multimeters (equivalent or better)
•
Alternatively; four equivalent voltage meters and two equivalent current meters. The current meters
must be capable of measuring greater than 3 A of current. A current meter in series with the
battery or battery simulator must have auto-ranging disabled and should only be used for DC
measurements (no start-up, transients, and so forth).
5.
Computer:
A computer with at least one USB port and a USB cable
6.
PC communication interface:
EV2400 USB-based PC interface board
