Evaluation Kit and GUI
This user manual demonstrates basic operations of the GUI and ISL94216 Evaluation Kit. Use this document in
the sequence it was written, each section assumes the previous section was completed. See the
ISL94216
datasheet for detailed information.
Software
The ISL94216 Evaluation Board GUI Code zip file must be downloaded from the Documentation and Downloads
section of the
ISL94216EVKIT1Z
board page. The ISL94216 GUI is built on top of Excel using Visual Basic for
Applications (VBA 1.00). It is designed to allow you to perform detailed evaluation of the ISL94216 and also
includes a simplified demonstration GUI.
Hardware
The ISL94216 Evaluation Kit consists of the following components:
• ISL94216EV1Z - ISL94216 evaluation board
• ISO-DONGLE-EV1Z - ISL94216 communications dongle with USB cable
• BMS-PS-CELL16Z - A 16-cell resistor ladder board
The following equipment is also needed to complete an evaluation of the device:
• Power supply (or battery pack)
• Current meter
• Voltmeter
