MAX78615+PPM/A03

Overview

The MAX78615+PPM/A03 is an isolated energy measurement processor designed for load monitoring and control in single-phase or split-phase AC circuits. It integrates a 24-bit processor with field-upgradeable firmware to perform signal processing, compensation, and data formatting. The device supports flexible sensor configurations, including up to two MAX78700 sensors, and features integrated flash memory for nonvolatile storage of calibration coefficients.

Feature Summary

• Best-in-class embedded algorithms support highly accurate electricity measurements
• Internal 24-bit processor performs real-time signal processing and data formatting
• Integrated flash memory provides nonvolatile storage for input configurations and calibration coefficients

Applications

• Load monitoring units
• Power supply systems
• Energy metering systems on a chip

Procurement Notes

Verify the specific suffix A03 against official Maxim Integrated documentation to confirm exact packaging and temperature grade specifications. Ensure compatibility with the intended host interface options and sensor configuration requirements before procurement.

Selection Notes

Select this component for applications requiring isolated energy measurement without large current sensors or optocouplers. Consider the need for field-upgradeable firmware and the integration of alarm monitoring and fault detection schemes to minimize host interface overhead.

Part Context

This part belongs to the MAX78615 family of isolated energy measurement processors. It is designed to work with companion sensors like the MAX78700 to provide a complete metering solution. The +LMU and +PPM variants indicate different package or performance grades within the same functional family.
