Microchip (MCP3909-I/SS) Aec-q100, Energy Metering IC, 16 Bit Dual ADC

AEC-Q100, Energy Metering IC, 16 Bit Dual ADC, 4.5 V to 5.5 V, SSOP-24 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 Applications Metering, Industrial, Automotive Product Information IC Function: Energy Metering IC Supply Voltage Min: 4.5V Supply Voltage Max: 5.5V IC Package Type: SSOP No. of Pins: 24Pins Operating Temperature Min: -40°C Operating Temperature Max: 85°C Product Range: - Automotive Qualification Standard: AEC-Q100 MSL: MSL 1 - Unlimited
