产品概述
MCP3909-I/SS is an energy metering IC with SPI interface and active power pulse output. It is an energy-metering IC 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. The 16-bit, delta-sigma ADCs allow for a wide range of IB and IMAX currents and/or small shunt (<lt/>200 µOhms) 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 per°C.
- Digital waveform data access through SPI interface
- Dual functionality pins support serial interface access and simultaneous active power pulse output
- Two 16-bit second order delta-sigma Analog to-Digital converters (ADCs) with multi-bit DAC
- A/D converter signal-to noise and distortion ratio is 81dB typ (VIN=0dBFS at 50Hz (VIN=Full Scale))
- Active energy measurement error is 0.1% FOUT typ (AVDD = DVDD = 4.5 to 5.5V, TA = -40 to +85°C)
- 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
- Tamper output pin for negative power indication
- 24 pin SSOP package, industrial operating temperature range from -40 to 85°C
