MAX78615+PPM/A03T

Overview

The MAX78615+PPM/A03T is an isolated energy measurement processor (EMP) designed for load monitoring and control in AC circuits. It supports flexible sensor configurations, including up to two MAX78700 sensors with four analog inputs. The device integrates a 24-bit processor and field-upgradeable firmware to perform signal processing, compensation, and data formatting for accurate real-time measurement. Internal flash memory stores input configurations and calibration coefficients non-volatilely.

Feature Summary

• Best-in-class embedded algorithms support highly accurate electricity measurements
• Integrated flash memory provides nonvolatile storage of input configurations and calibration coefficients
• Field upgradeable firmware performs necessary signal processing and data formatting

Applications

• Load monitoring and control of 2-wire single-phase AC circuits
• Load monitoring and control of 3-wire split-phase (120/180°) AC circuits
• Energy accumulation and alarm monitoring systems
• Fault detection schemes in metering applications

Procurement Notes

Verify the specific suffix A03T against official Maxim Integrated documentation to confirm package type and temperature range. Ensure compatibility with the MAXREFDES14# development kit if prototyping. Confirm RoHS compliance status through the manufacturer's certification documents before finalizing procurement specifications.

Selection Notes

Select this component for applications requiring isolated energy measurement in single-phase or split-phase AC environments. The integrated processor reduces host interface overhead by handling signal processing internally. Consider the need for field-upgradeable firmware and nonvolatile configuration storage when evaluating system architecture requirements.
