REFERENCE DESIGN

Chapter 1. Product Overview

1.1 INTRODUCTION

This chapter provides an overview of the MCP3905A/06A Energy Meter Reference

Design and covers the following topics:

• What is the MCP3905A/06A Energy Meter Reference Design?

• What the MCP3905A/06A Energy Meter Reference Design Kit includes

1.2 WHAT IS THE MCP3905A/06A ENERGY METER REFERENCE DESIGN

The MCP3905A/06A Energy Meter Reference Design device is an energy metering IC

that supplies average active power information via a pulse output with direct drive for

mechanical counters. It also includes a higher-frequency output that supplies

instantanous power information for calibration. The device contains function blocks

specific for IEC energy meter compliance, such as a no-load threshhold and startup

current.

The MCP3905A/06A Energy Meter Reference Design Printed Circuit Board (PCB) is

used as a reference design for single-phase, residential meters. The MCP3905A/06A

Energy Meter Reference Design kit includes all necessary PCB circuits and layout tips

for IEC62053 and prior 1036/61036/687 active-energy meter standards compliance.

For more information regarding IEC compliance, refer to AN994, “IEC Compliant Active

Energy Meter Design Using The MCP3905A/06A Energy Meter Reference Design”

(DS00994).
