78M6612  
Single-Phase, Dual-Outlet  
Power and Energy Measurement IC  
DATA SHEET  
DS_6612_001  
FEATURES  
DESCRIPTION  
Measures Each Outlet of a Duplex Receptacle with  
a Single IC  
The Teridian™ 78M6612 is a highly integrated, single-phase,  
power and energy measurement and monitoring system-on-  
chip (SoC) that includes a 32-bit compute engine (CE), an  
MPU core, RTC, and flash. Our Single Converter  
Technology® with a 22-bit delta-sigma ADC, four analog  
inputs, digital temperature compensation, and precision  
voltage reference supports a wide range of single-phase,  
dual-outlet power measurement applications with very few  
external components.  
Provides Complete Energy Measurement and  
Communication Protocol Capability in a Single IC  
Intelligent Switch Control Capability  
< 0.5% Wh Accuracy Over 2000:1 Current Range  
and Over Temperature  
Exceeds IEC 62053/ANSIC12.20 Standards  
Voltage Reference < 40 ppm/°C  
Four Sensor Inputs – VDD Referenced  
Low Jitter Wh and VARh Pulse Test Outputs  
(10 kHz max)  
With measurement technology leveraged from Maxim’s flagship  
utility metering ICs, the device offers features including 32 KB  
of flash program memory, 2 KB shared RAM, three low-power  
modes with internal timer or external event wake-up, two  
UARTs, I2C/MICROWIRE® EEPROM I/F, and an in-system  
programmable flash. Complete outlet measurement unit (OMU)  
and AC power monitor (AC-PMON) firmware is available or can  
be preloaded into the IC.  
Pulse Count for Pulse Outputs  
Line Frequency Count for RTC  
Digital Temperature Compensation  
Sag Detection for Phase A and B  
Independent 32-Bit Compute Engine  
46-64 Hz Line Frequency Range with Same Calibration  
Phase Compensation (±7°)  
Battery Backup for RTC and Battery Monitor  
Three Battery Modes with Wake-Up Timer:  
Brownout Mode (48 µA)  
A complete array of ICE and development tools, programming  
libraries and reference designs enable rapid development and  
certification of power and energy measurement solutions that  
meet the most demanding worldwide electricity metering  
standards.
