The MCP39F511N is a highly integrated, dual-channel single-phase power-monitoring IC designed for real-time measurement of power for dual-socket wall outlets, power strips, AC/DC power supplies, and power distribution applications. It includes three ADCs for voltage and two current load measurements, 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 current measurement channel allows for better than 0.5% accurate designs across a 4000:1 dynamic range.
Additional Features
Power Monitoring of Two Loads
Capable of 0.5% 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
Fast Calibration Routines
2-wire UART: Selectable Baud Rate up to 115.2kbps
512 bytes User-accessible EEPROM through page read/write commands
Low-Drift Internal Voltage Reference: 10 ppm/°C typical
28-lead 5x5 QFN package
Extended Temperature Range -40°C to +125°C
AEC-Q100 Grade 1
