MCP39F501T-E/MQ

Overview

The MCP39F501T-E/MQ is a single-phase power monitoring IC designed for real-time measurement of AC power sources. It integrates two 24-bit delta-sigma analog-to-digital converters (ADCs), a 16-bit calculation engine, and EEPROM memory within a 28-pin QFN package. The device operates on a supply voltage ranging from 2.7 V to 3.6 V with a typical operating current of 13 mA. It achieves an accuracy of 0.1% and supports a dynamic range of 4000:1. The component is qualified under AEC-Q100 standards and functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Integrates dual 24-bit ADCs and a 16-bit calculation engine for high-precision power monitoring without external transformers.
• Includes internal EEPROM for storing calibration data and critical event logs to support fault diagnosis.
• Provides flexible two-wire interface connectivity and calculates standard power metrics including active, reactive, and apparent power.

Applications

• Smart lighting systems requiring precise energy metering
• Solar inverters utilizing AC as the primary power source
• Cloud servers needing reliable power consumption monitoring

Procurement Notes

Verify that the specific suffix T/E/MQ matches the required tape-and-reel packaging and automotive-grade qualification. Confirm the 28-VFQFN footprint aligns with the target PCB layout. Ensure the design accounts for the 2.7 V to 3.6 V supply voltage constraints and the -40°C to +125°C operational temperature range specified in the datasheet.

Selection Notes

Select this component when designing single-phase AC power monitoring solutions that demand high accuracy and integrated signal processing. It is suitable for applications requiring low component count and reduced firmware development time due to built-in calculation engines. Consider the AEC-Q100 qualification if the deployment environment requires automotive reliability standards.

Part Context

This part belongs to Microchip's MCP39F series of power monitoring integrated circuits. It serves as a specialized solution for single-phase energy metering, distinguishing itself through high integration levels that eliminate the need for external transformers.
