The MCP39F521 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.
Additional Features
Power Monitoring Accuracy capable of 0.1% error across 4000:1 dynamic range
Built-In Calculations on Fast 16-Bit Processing Core
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
I2C Interface
512 bytes User-accessible EEPROM through page read/write commands
Non-volatile On-chip Memory, no external memory required
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
