Product Overview

The MCP3909-I/SS is an Energy Metering IC with SPI interface, active power pulse output and high field reliability. It is designed to support the IEC 62053 international metering standard specification. It supplies a frequency output proportional to the average active real power with simultaneous serial access to ADC channels and multiplier output data. This output waveform data up to 14kHz with 16-bit ADC output and 20-bit multiplier output words. The 16-bit, delta-sigma ADC allows for a wide range of IB and IMAX currents or small shunt (<200µOhms) meter designs. A no-load threshold block prevents any current creep measurements for the active power pulse outputs. The integrated on-chip voltage reference has an ultra-low temperature drift of 15ppm/°C.
  • Digital waveform data access through SPI interface
  • Dual functionality pins support serial interface access
  • Simultaneous active power pulse output
  • Two 16-bit second order delta-sigma analogue-to-digital converters (ADCs) with multi-bit DAC
  • 0.1% Typical active energy measurement error over 1000:1 dynamic range
  • PGA for small signal input supports low value shunt current sensor
  • Direct drive for electromagnetic mechanical counter and two-phase stepper motors
  • Low IDD of 4mA (maximum)
  • Tamper output pin for negative power indication
