to supply power to the Demo board. The Demo board can accept
voltages from 4.5V to 36V.
The board is properly powered by the battery pack with the most
negative voltage connected to the left of the VIN connector at the
top of the ISL28023 Demo board. This is illustrated in
Once properly powered, launch the ISL28023 software. The
same software used to control the ISL28023 generic board.
Press the "Connect To Device" button. The software will scan all
allowable slave addresses and determine the type of board
connected to the dongle. If the demo board is successfully
connected to the dongle, the window in

All the controls and features discussed in the ISL28023 generic
board software are available to the user in the Demo software.
The ISL28023 Demo board connects the ISL28023 to a buck
regulator (ISL85415) and some resistive loads.
The current going into the regulator is monitored by the Vshunt
inputs (Vinp, Vinm) and a shunt resistor of 0.02Ω (R
VauxShunt inputs (Aux_P, Aux_N) are connected across a 0.02Ω
shunt resistor (R
). The VauxShunt channel measures the

current going to the load. The Vaux input measures the regulated

voltage at the load. The Vbus input measures the voltage applied
at VIN terminator. The current and power displays represent the
current and power being sourced to the regulator and load.
Press the "ON" button in the lower right hand corner to turn on
the ISL85415. The Vbus, Vshunt, Current, Power, Vaux channels
will turn on if they are not currently active.
