78M6631-IM/F

The 78M6631-IM/F is a 3-phase power measurement IC in 56 pin TQFN package. This is a highly integrated power measurement and monitoring system-on-chip (SoC) with a 10MHz 8051-compatible MPU core and Single Converter Technology containing a 22bit delta sigma converter and 32bit compute engine (CE). It 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, device provides 6 analogue inputs including 3 differential current and 3 voltage for interfacing to current and voltage sensors. Device provides better than 0.5% accuracy over a wide 2000:1 dynamic range. The integrated MPU core and 128KB 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. It is used in building automation, solar inverters & motor health.
