Overview

The MCP39F511A-E/MQ is a highly integrated single-phase power monitoring IC designed for real-time measurement of input power. It features dual-channel 24-bit Delta-Sigma ADCs and a 16-bit calculation engine to provide accurate measurements of active, reactive, and apparent power, as well as RMS current and voltage.

Why Choose This Part

The device offers industry-leading accuracy of 0.1 percent over a wide dynamic range, reducing the need for complex calibration. It integrates 512 bytes of user EEPROM for storing calibration constants and device configuration, while the 28-QFN package simplifies thermal management and board space constraints.

Applications

Smart Plugs and Power Strips
Accurately monitors energy consumption and power quality for consumer appliances with a small 5x5mm QFN footprint.
EV Charging Stations
Provides precise metering for Level 1 and Level 2 AC charging equipment to ensure accurate billing and safety monitoring.
