• Description: Isolated Sensor Ics
• Manufacturer: Maxim Integrated Products, Inc.

71M6x01. This single-phase configuration uses one local shunt and one shunt isolated with a 71M6x01
device. Since the local shunt is connected to the LINE circuit, the meter is also referenced to the LINE
circuit.

71M6545/H. This polyphase configuration uses three 71M6xx3 to isolate the shunt sensors for the three
phases, while a locally connected fourth shunt sensor can be optionally used to sense neutral current.
Since the local shunt is connected to the neutral circuit, the meter is also referenced to the neutral circuit.
