PI2127-EVAL1 60V/12A Full-Function High Side Active ORing
Evaluation Board User Guide
The PI2127-EVAL1 Evaluation Board is intended to
acquaint the user with the benefits and features of the
Cool-ORing
®
PI2127 full-function Active ORing solution. It
is not designed to be installed in end-use equipment.
Please read this document before setting up the PI2127-
EVAL1 Evaluation Board and refer to the PI2127 product
datasheet
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 PI2127-EVAL1 allows the user to test the basic
principles and operational characteristics of an Active
ORing function in a redundant power architecture, while
also experiencing the benefits and value of the PI2127
solution versus conventional Active ORing solutions. The
PI2127-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 12A, and is
suitable redundant bus voltages up to 48V.
The PI2127-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 48V BUS applications
requiring up to 12A. This evaluation board is intended as
an easy and simple way to test the electrical and thermal
performance of the PI2127 Full-Function Active ORing
solution.
Both dynamic and steady state testing of the PI2127 can
be completed on the PI2127-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 PI2127 can be
found in the PI2127 product datasheet.
