The 71M6545-IGT/F is a metrology processor designed for 3-phase energy metering applications. It integrates a 22-bit delta-sigma ADC and a 32-bit computation engine for core metrology functions, along with an 8051-compatible application processor. This IC supports isolated current sensing products, offering reduced component count and immunity to magnetic tampering.
Key features include 0.1% typical accuracy over a 2000:1 current range, exceeding IEC 62053/ANSI C12.20 standards. It provides seven sensor inputs with neutral current measurement and selectable gain for shunt resistors. The device integrates an accurate Real-Time Clock (RTC) with automatic temperature compensation for Time-of-Use (TOU) functions.
This energy metering IC operates with a supply voltage between 3V and 3.6V and has an operating temperature range of -40°C to 85°C. It is housed in a 64-LQFP (10x10) surface mount package, making it suitable for various energy meter designs requiring precise measurement and processing capabilities.
