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.

featuring the Cool-ORing PI2002

Active ORing controller.

Cool-ORing™ Series

The PI2002-EVAL1 Evaluation Board is intended to acquaint the

user with the benefits and features of the Cool-ORing

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.
