1 INTRODUCTION
This data sheet covers the 71M6545 (0.5%) and 71M6545H (0.1%) fourth generation Teridian poly-phase
Metrology Processors. The term “71M6545/H” is used when discussing a device feature or behavior that
is applicable to both part numbers. The appropriate part number is indicated when a device feature or
behavior is being discussed that applies only to a specific part number. This data sheet also covers
details about the companion 71M6xx3 isolated current sensor device.
This document covers the use of the 71M6545/H in conjunction with the 71M6xx3 isolated current sensor.
The 71M6545/H and 71M6xx3 ICs make it possible to use one non-isolated and three additional isolated
shunt current sensors to create poly-phase energy meters using inexpensive shunt resistors, while
achieving unprecedented performance with this type of sensor technology. The 71M6545/H Metrology
Processors also support Current Transformers (CT).
