What Is Inside

The evaluation kit contains:

• ISL76534EVAL1Z board

• The 

ISL76534

 datasheet

• This ISL76534EVAL1Z user guide

• ISLUSBMINIZEVAL1Z (USB to I

2

C module)

What Is Needed

The following instruments will be needed to perform testing:

• Power supplies: 

- PS1:  DC  20V/5A,  (between  A

VDD

 and A

VDD

_AMP and GND)

- PS2:  DC  20V/5A,  (between  D

VDD

 and GND)

• Multimeters
• Oscilloscope
• Cables and wires

Initial Set-Up

This user guide describes how to set up and use the 
ISL76534EVAL1Z evaluation board along with the 
ISLUSBMINIZEVAL1Z in a standalone configuration. It explains 
how to install the software and how to use the Windows interface 
to read and write to the ISL76534 data register and EEPROM.

Evaluation Software

The next section explains how to install the Graphical User 
Interface (GUI) software, which is used to configure the ISL76534 
data registers and EEPROM.

Notes

The GUI software was developed on a 64-bit Windows 8 platform. 
Because the GUI software registers as a Human Interface Device 
(HID) and uses standard HID calls, it should also work on other 
XP or later Windows operating systems (32-bit and 64-bit), 
including Windows 7.

This user guide contains screenshots of the GUI at the time this 
user guide was written. Subsequent GUI versions may appear 
differently.
