78M6612 Energy Measurement Chip

The Teridian 78M6612 is a highly integrated, single phase AC power measurement and monitoring (AC-PMON) IC for consumer and enterprise applications capable of 0.5% Wh or better accuracy over 2000:1 current range and over temperature. Four analog inputs are provided for measuring up to two AC loads or wall outlets using Teridian’s patented Single Converter Technology™ and 32-bit computation engine (CE).
The 78M6612 device also includes an 8-bit MPU core with 32KB of embedded FLASH, a UART interface, and a number of GPIO for easy integration into any power supply or outlet monitoring unit. The 78M6612 is available in both 64-LQFP and 68-QFN lead free package options and consumes roughly 30mW under typical operating conditions.

Complete firmware is available from Teridian supporting the serial UART interface for simplified calibration, configuration, and data extraction. Firmware options for emulating I2C, PMBus, or SMBus interfaces using GPIO are also available. Firmware can be pre-loaded into the IC by Teridian or modified by customers as needed.
