Microchip Technology MCP39F501-E/MQ

Description
The MCP39F501 is a single-phase power-monitoring IC designed for real-time measurement of input power in AC/DC power supplies, power distribution units, and industrial applications. It features dual-channel delta-sigma ADCs, a 16-bit calculation engine, EEPROM, and a flexible 2-wire interface. With an integrated low-drift voltage reference and high SINAD performance, it enables accurate designs with an error of less than 0.1% across a 4000:1 dynamic range.

Features
Power monitoring accuracy of 0.1% across a 4000:1 dynamic range
Fast calibration routines
Programmable event notifications for over-current, voltage sag, and surge protection
512 bytes of user-accessible EEPROM with page read/write commands
Non-volatile on-chip memory, eliminating the need for external memory
Built-in calculations on a fast 16-bit processing core:
Active, reactive, and apparent power
True RMS current, RMS voltage
Line frequency, power factor
Two-wire serial protocol using a UART interface supporting multiple devices on a single bus
Low-drift internal voltage reference with 10 ppm/°C typical
28-lead 5x5 QFN package
Extended temperature range: -40°C to 125°C

Applications
Real-time measurement of input power for AC/DC supplies
Intelligent power distribution units
