MCP39F501

MCP39F501 Single-Phase, Power-Monitoring IC with Calculation and Event Detection 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 commands 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 dB of SINAD performance on each measurement channel allows for better than 0.1% accurate designs across a 4000:1 dynamic range.
