MAX78630+PPM Energy Measurement Processor for Polyphase Monitoring Systems DATA SHEET GENERAL DESCRIPTION The MAX78630+PPM is an energy measurement processor (EMP) for polyphase power monitoring systems. It is designed for real-time monitoring for a variety of typical three-phase configurations in industrial applications. It is available in a 32-pin TQFN package. The MAX78630+PPM provides up to six analog inputs for interfacing to voltage and current sensors. Scaled voltages from the sensors are fed to the single converter front-end utilizing a high-resolution delta-sigma converter. Supported current sensors include current transformers (CT), Rogowski coils, and resistive shunts. An embedded 24-bit measurement processor and firmware perform all necessary computations and data formatting for accurate reporting to the host. With integrated flash memory for storing nonvolatile calibration coefficients and device configuration settings, the MAX78630+PPM is capable of being a completely autonomous solution. The MAX78630+PPM is designed to interface to the host 2 processor via the UART interface. Alternatively, SPI or I C may also be used.
