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 TM 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.
