Description
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.
Features
- 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
- Fast Calibration Routines
- 2-wire UART: 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 qualified
Typical applications
- Power Monitoring for connected goods
