MCP39F511-E/MQ

The MCP39F511-E/MQ is a highly integrated Power-monitoring IC with calculation and energy accumulation. The complete single-phase power-monitoring IC designed for real-time measurement of input power for AC/DC power supplies and power distribution units. 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 10ppm/°C in addition to 94.5dB of SINAD performance on each measurement channel allows for better than 0.1% accurate designs across a 4000:1 dynamic range.

• Power Monitoring Accuracy capable of 0.1% error across 4000:1 dynamic range
• Built-in calculations - Active, reactive, apparent power, line frequency and power factor
• Dedicated zero crossing detection (ZCD) pin
• Dedicated PWM output pin
• Automatic event pin control through fast voltage surge detection
• Fast calibration routines and simplified command protocol
• 10ppm/°C Typical low-drift internal voltage reference
• 512 Bytes user-accessible EEPROM through page read/write commands
• 2-wire UART - Baud Rate up to 115.2kbps
