MCP39F501 Datasheet | Microchip Technology

Features : - Power Monitoring Accuracy capable of 0.1% error across 4000:1 dynamic range - Fast Calibration Routines - Programmable Event Notifications such as overcurrent and voltage sag, surge protection - 512 bytes User-accessible EEPROM through page read/write mands - Non-volatile On-chip Memory, no external memory required - Built-in calculations on 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 2-wire Universal Asynchronous Receiver/Transmitter (UART) interface supporting multiple devices on a single bus - Low-Drift Internal Voltage Reference, 10 ppm/°C typical - 28-lead 5x5 QFN package - Extended Temperature Range -40°C to +125°C Description : The MCP39F501 is a highly integrated, single-phase power-monitoring IC designed for real-time measurement of input power for AC/DC power supplies, power distribution units and industrial applications. 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 with 10 ppm/°C in addition to 94.5 d B of SINAD performance on each measurement channel allows for better than 0.1% accurate designs across a 4000:1 dynamic range.
