MAX78630+PPM/D00T

The MAX78630+PPM/D00T from Analog Devices (formerly Maxim Integrated) is a specialized energy measurement processor (EMP) engineered for real-time monitoring in polyphase power systems. It is particularly suited for industrial applications requiring accurate monitoring of three-phase configurations.

This processor features six configurable analog inputs, allowing interface with various voltage and current sensors, including current transformers (CT), Rogowski coils, and resistive shunts. It utilizes a high-resolution delta-sigma analog-to-digital converter (ADC) front-end for precise measurements. An embedded 24-bit measurement processor with integrated firmware handles all necessary computations and data formatting, enabling autonomous operation with non-volatile flash memory for calibration coefficients and configuration settings.

The MAX78630+PPM/D00T is housed in a compact 32-pin TQFN package, facilitating reduced bill of materials and smaller PCB footprints. It offers flexible interface options including UART, SPI, and I2C for communication with host processors. Configurable I/O pins can be used for alarm signaling, address pins, or user control, enhancing system integration flexibility. The device operates within a supply voltage range of 3V to 3.6V and has an operating temperature range of -40°C to 85°C.
