Introduction

The PI2121-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 PI2121 solution versus conventional

Active ORing solutions. The PI2121-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 is capable of up to 24

A, and is suitable for redundant bus voltages up to 5 V. For

high current Active ORing, above 24 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 PI2121-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 ≤ 5V bus applications requiring up to 24 A.

This evaluation board is intended as an easy and simple way

to test the electrical and thermal performance of the PI2121

Full-Function Active ORing solution.

Both dynamic and steady state testing of the PI2121 can be

completed on the PI2121-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 PI2121 can be found

in the PI2121 product data sheet.

PI2121-EVAL1 Evaluation Board

featuring the Cool-ORing PI2121

Full-Function Active ORing Solution.

Cool-ORing™ Series

The PI2121-EVAL1 Evaluation Board is intended to acquaint the

user with the benefits and features of the Cool-ORing

PI2121

full function Active ORing solution. It is not designed to be

installed in end-use equipment.

Please read this document before setting up the PI2121-EVAL1

Evaluation Board and refer to the PI2121 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.
