The SY7T612 is an energy measurement processor (EMP), in a 32QFN package, designed specifically for BOM optimized applications. It suited for accurate measurement and power quality analysis in single-phase (multiple branches) or polyphase systems.
The analog front end (AFE) provides configurable analog inputs for interfacing to current sensors and voltage sensors respectively. Scaled voltages from the sensors are fed to a high-resolution delta-sigma converter. A low power Energy Measurement Processor (EMP) performs the signal processing and data formatting for interfacing to any host controller. With integrated flash memory for storing nonvolatile data such as calibration coefficients and input configuration settings, the device provides an autonomous solution that simplifies system integration.
