Overview
The MAX78615+PSU/A00 is an isolated energy measurement processor (EMP) 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
- Integrates best-in-class embedded algorithms for highly accurate electricity measurements
- Provides flexible sensor configuration supporting multiple analog inputs via external sensors
- Features internal 24-bit processor with field-upgradeable firmware for real-time measurement
- Includes integrated flash memory for nonvolatile storage of input configurations and calibration coefficients
Applications
- Isolated energy measurement for load monitoring units
- Control of 2-wire single-phase AC circuits
- Control of 3-wire split-phase (120/180°) AC circuits
- Power supply unit (PSU) metering systems on a chip
Procurement Notes
Verify the specific suffix A00 against official Analog Devices documentation to confirm it denotes the PSU evaluation kit or development board rather than the standalone IC. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may be restricted. Ensure the intended application matches the isolated EMP architecture described in the datasheet.
Selection Notes
Select this component when designing isolated metering systems requiring high accuracy without large current sensors or optocouplers. The integrated flash and field-upgradeable firmware allow for long-term adaptability. Consider the host interface options for easy integration into existing system architectures. Verify that the supported voltage ranges match the target AC circuit requirements.
Part Context
This part belongs to the MAX78615 family of isolated energy measurement processors. It is often paired with the MAX78700 current sensor structure. The +PSU/A00 designation typically indicates a specific packaging or evaluation variant within the Maxim Integrated product line, focusing on power supply applications.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source material. Consult Analog Devices technical support for potential alternatives if this specific variant is discontinued.
