71M6515H
Energy Meter IC
Industry's Most Integrated Metering SoC Product Line and Best-in-Class Accuracy Performance
Part Details
- < 0.1% Wh Accuracy Over Temperature and 2000:1 Range
- Protects Accumulated Data and Powers RTC During Power-Supply Outage
- UART Control Interface, Two Selectable Data Rates
- Low System Cost
The 71M6515H is a high-accuracy analog front-end (AFE) IC that provides measurements for four-quadrant 3-phase metering. The combination of a 21-bit sigma-delta analog-to-digital converter with a six-input AFE, a thermally compensated high-precision reference, and a compute engine results in high accuracy and wide dynamic range. Our Single Converter Technology® reduces crosstalk and cost. This IC also provides a real-time clock (RTC) and battery backup for time-of-use (TOU) metering.
The host processor communicates with the 71M6515H through a UART interface using the programmable IRQZ interrupt. The 71M6515H calculates and accumulates meter measurements for each accumulation interval. A high-speed synchronous serial port (SSI) is provided to facilitate high-end metering. Integrated rectifying functions on the battery-backup circuit enable minimal external component usage and minimum backup current. Also, eight multipurpose pins are provided for control of peripherals.
