MCP39F511A AC/DC Dual-Mode Power Monitors

Microchip's MCP39F511A is a highly integrated, single-phaser phase, real-time measurement power power-monitoring IC

Image of Microchip's MCP39F511A AC/DC Dual-Mode Power-Monitors Microchip Technology's MCP39F511A device is a complete single-phase, highly integrated, power-monitoring IC designed for real-time measurement of input power for AC or DC power supplies. It includes dual-channel Delta-Sigma ADCs, a 16-bit calculation engine, EEPROM, and a flexible 2-wire interface. Separate AC and DC calibration registers are provided to ensure high-accuracy measurements in both modes. An integrated low-drift voltage reference with 7 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. The MCP39F511A comes in a 5x5 QFN package. The rich feature-set of this device makes it suitable for a wide range of consumer and industrial applications including power supplies, home IoT devices, industrial power meters, and commercial lighting.

  • Real-time measurement of input power for AC or DC supplies
  • AC/DC dual-mode power monitoring accuracy capable of 0.1%
  • Automatic sensing and switching between AC and DC modes
  • Built-in calculations on a fast 16-bit processing core
  • 512 bytes user-accessible EEPROM through page read/write commands
  • Low-drift internal voltage reference, 7 ppm/°C typical
  • 28-lead 5x5 QFN package extended temperature range -40°C to +125°C
  • Built-in calculations allow the designer to easily add high-performance power monitoring capability to their applications which reduces time to market
  • Fast calibration routines and simplified command protocol reduces design riskBridge
