Cool-ORing™ Series
PI2003-EVAL1 Evaluation Board
featuring the Cool-ORing PI2003
Active ORing controller.
The PI2003-EVAL1 Evaluation Board is intended to acquaint the
user with the benefits and features of the Cool-ORing^TM PI2003
full function Active ORing solution. It is not designed to be
installed in end-use equipment.
Please read this document before setting up the PI2003-EVAL1
Evaluation Board and refer to the PI2003 product data sheet
for device specifications, functional description and
characteristics.
During operation, the power devices and surrounding
structures can be operated safely at high temperatures.
• Remove power and use caution when connecting and
disconnecting test probes and interface lines to avoid
inadvertent short circuits and contact with hot surfaces.
• When testing electronic products always use approved
safety glasses. Follow good laboratory practice and
procedures.
Introduction
The PI2003-EVAL1 allows the user to test the basic principle
and operational characteristics of a low side Active ORing
function in a redundant power architecture, while also
experiencing the benefits and value of the PI2003 solution
versus conventional Active ORing solutions. The PI2003-EVAL1
evaluation board is configured to receive two independent
power source inputs, per a typical redundant power
architecture, through two Active ORing channels that are
combined to form a redundant power output. Each channel
contains a PI2003 controller and an N-channel power
MOSFET. The MOSFET foot print can take an SO-8 or Power
SO-8 MOSFET package. Each channel is capable of up to 6 A.
The PI2003-EVAL1 evaluation board is designed with
optimized PCB layout and component placement to represent
a realistic high density final design for an embedded low side
Active ORing solution for -48 Vbus applications requiring up
to 6 A. This evaluation board is intended as an easy and
simple way to test the electrical and thermal performance of
the PI2003 Active ORing controller.
Both dynamic and steady state testing of the PI2003 can be
completed on the PI2003-EVAL1 evaluation board, in addition
to using the key features of the product. Dynamic testing can
be completed under a variety of system level fault conditions
to check for response time to faults.
This document provides basic instructions for initial start-up
and configuration of the evaluation board. Further
information on the functionality of the PI2003 can be
found in the PI2003 product data sheet.
