71M6515H-IGTW/F

Overview

The 71M6515H-IGTW/F is a high-accuracy analog front-end (AFE) integrated circuit designed for four-quadrant three-phase metering applications. It provides energy measurement accuracy better than 0.1% over a 2000:1 range across the full temperature spectrum. The device features an internal voltage reference and supports data protection during power loss, including backup power for the real-time clock (RTC). It utilizes a UART control interface with two selectable baud rates to facilitate system integration.

Feature Summary

• Provides high-precision measurements for four-quadrant three-phase energy metering
• Ensures data integrity during power outages with battery-backed RTC support
• Integrates a stable voltage reference for consistent signal accuracy
• Offers flexible communication via a dual-rate UART control interface

Applications

• Three-phase utility energy meters
• Industrial power monitoring systems
• Smart grid infrastructure devices

Procurement Notes
