Cool-ORing™ Series
PI2002-EVAL1 Evaluation Board
featuring the Cool-ORing PI2002
Active ORing controller.
The PI2002-EVAL1 Evaluation Board is intended to acquaint the
user with the benefits and features of the Cool-ORing^TM PI2002
Active ORing with Load Disconnect solution. It is not designed to
be installed in end-use equipment.
Please read this document before setting up the PI2002-EVAL1
Evaluation Board and refer to the PI2002 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 PI2002-EVAL1 allows the user to test the basic principle
and operational characteristics of an Active ORing with Load
Disconnect function in a redundant power architecture, while
also experiencing the benefits and value of the PI2002
solution versus conventional Active ORing solutions. The
PI2002-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 PI2002 controller and two N-channel
power MOSFETs (configured back-to-back). The MOSFET
footprints can take SO-8 or Power SO-8 MOSFET packages.
Each channel is capable of up to 20 A.
The PI2002-EVAL1 evaluation board is designed with
optimized PCB layout and component placement to represent
a realistic high density final design for an embedded Active
ORing with Load Disconnect solution for ≤ 7 Vbus
applications requiring up to 20 A. This evaluation board is
intended as an easy and simple way to test the electrical and
thermal performance of the PI2002 Active ORing with Load
Disconnect controller.
Both dynamic and steady state testing of the PI2002 can be
completed on the PI2002-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 PI2002 can be
found in the PI2002 product data sheet.
