ISL97671/2/3/4IRZ-EVAL Quick Start Guide
This quick start guide pertains to the
ISL97671/2/3/4IRZ-EVAL Evaluation Board. This board
comes populated with 72 LEDs in a 6P12S configuration
to simplify evaluation and testing. Please install the
Sunlight ISL97670 GUI from Intersil's website, which will
be used to control ISL97671/3/4 parts via I
slave address on the ISL97671, ISL97673 and ISL97674
is hexadecimal 58; see Figure 1. Please refer to
"ISL97671" on page 1, "ISL97672" on page 2,
"ISL97673" on page 2 and "ISL97674" on page 3, for
jumper settings and power-up instructions.
