Microchip MCP39F511A-E/MQ, Current Monitor 28-Pin, QFN

The MCP39F511 is a highly integrated, single-phase power-monitoring IC designed for real-time measurement of input power for AC/DC power supplies, providing power and energy values. It includes dual-channel delta sigma ADCs, a 16-bit calculation engine, EEPROM and a flexible 2-wire interface. An integrated low-drift voltage reference in addition to the 94.5 dB of SINAD performance on each measurement channel allows for better than 0.1% accurate designs across a 4000:1 dynamic range.Power Monitoring Accuracy capable of 0.1% error across 4000:1 dynamic range Built-In Calculations: Active, Reactive, Apparent Power Active and Reactive Energy Accumulation True RMS Current, RMS Voltage Line Frequency, Power Factor Dedicated Zero Crossing Detection (ZCD) Pin Dedicated PWM Output Pin Automatic Event Pin Control through Fast Voltage Surge Detection
