Introduction

The PI2001-EVAL1 allows the user to test the basic principle

and operational characteristics of an Active ORing function in

a redundant power architecture, while also experiencing the

benefits and value of the PI2001 solution versus conventional

Active ORing solutions. The PI2001-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 PI2001

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 20 A, for high current Active

ORing, above 20 A, the two channels provided on the

evaluation board can be paralleled in a master / slave

configuration and OR’d with a second evaluation board.

The PI2001-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 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 PI2001

Active ORing controller.

Both dynamic and steady state testing of the PI2001 can be

completed on the PI2001-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 PI2001 can be

found in the PI2001 product data sheet.

PI2001-EVAL1 Evaluation Board

featuring the Cool-ORing PI2001

Universal Active ORing controller.

Cool-ORing™ Series

The PI2001-EVAL1 Evaluation Board is intended to acquaint the

user with the benefits and features of the Cool-ORing

PI2001

Universal Active ORing controller. It is not designed to be

installed in end-use equipment.

Please read this document before setting up the PI2001-EVAL1

Evaluation Board and refer to the PI2001 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.
