MAXIM INTEGRATED PRODUCTS  78M6610+LMU/B01  芯片, 特殊功能

The is an energy measurement processor for load monitoring units in 24 pin TQFN package. It is an energy measurement processor EMP for load monitoring and control of any 2 wire single phase or 3 wire split-phase 120/180° AC circuit. It provides flexible sensor configuration of four analogue inputs and numerous host interface options for easy integration into any system architecture. The internal 24bit processor and field upgradeable firmware performs all the necessary signal processing, compensation and data formatting for accurate real-time measurement. Energy accumulation, alarm monitoring and fault detection schemes minimize the overhead requirements of the host interface and/or network. The integrated flash memory also provides for non-volatile storage of input configurations and calibration coefficients.
