78M6631
3-Phase Power-
Measurement IC
DATA SHEET
DS_6631_056
DESCRIPTION
The Teridian? 78M6631 is a highly integrated 3-phase
power measurement and monitoring system-on-chip
(SoC), with a 10 MHz 8051-compatible MPU core and
Single Converter Technology? containing a 22-bit delta-
sigma converter and 32-bit compute engine (CE). The
78M6631 has been designed specifically for a wide
variety of applications requiring 3-phase power and
quality measurements. It supports both Delta and Wye
configurations.
At the measurement interface, the device provides six
analog inputs including three differential current and three
voltage for interfacing to current and voltage sensors. The
device provides better than 0.5% accuracy over a wide
2000:1 dynamic range.
The integrated MPU core and 128 KB of flash memory
provide a flexible means of configuration, post-
processing, data formatting, interfacing to host processor
via a UART or SPI interface, or using DIO pins for LEDs
or relay control. Complete firmware is available from
Maxim and can be loaded into the IC during
manufacturing test.
