Microchip Technology (Chandler, AZ) [NASDAQ: MCHP] has announced a new power monitoring IC, the MCP39F501.  This device is a highly integrated, single-phase power-monitoring IC designed for real-time measurement of AC power.  The device enables high-performance, cost-effective designs in the commercial (e.g., server and networking power supplies, power distribution units, lighting systems); consumer (e.g., appliance and smart plugs); and industrial markets (e.g., power meters and industrial equipment). The MCP39F501 features: 

  • 24-bit delta-sigma ADCs.
  • A 16-bit calculation engine.
  • EEPROM and a flexible two-wire interface. 
  • An integrated low-drift voltage reference.
  • 94.5 dB of SINAD performance on each measurement channel.
  • 0.1 % error across a 4000:1 dynamic range in designs.
  • An operating temperature range from -40 to +125°C.
