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).
