1 / 30 page  © 2009 Microchip Technology Inc. DS21948E-page 1 MCP3905/06 Features • Supplies active (real) power measurement for single-phase, residential energy-metering • Supports the IEC 62053 International Energy Metering Specification and legacy IEC 1036/ 61036/687 Specifications • Two multi-bit, Digital-to-Analog Converters (DACs), second-order, 16-bit, Delta-Sigma Analog-to-Digital Converters (ADCs) • 0.1% typical measurement error over 500:1 dynamic range (MCP3905) • 0.1% typical measurement error over 1000:1 dynamic range (MCP3906) • Programmable Gain Amplifier (PGA) for small- signal inputs supports low-value shunt current sensor - 16:1 PGA - MCP3905 - 32:1 PGA - MCP3906 • Ultra-low drift on-chip reference: 15 ppm/°C (typical) • Direct drive for electromagnetic mechanical counter and two-phase stepper motors • Low IDD of 4 mA (typical) • Tamper output pin for negative power indication • Industrial Temperature Range: -40°C to +85°C • Supplies instantaneous active (real) power on HFOUT for meter calibration US Patents Pending Description The MCP3905/06 devices are energy-metering ICs designed to support the IEC 62053 International Metering Standard Specification. They supply a frequency output proportional to the average active (real) power, as well as a higher-frequency output proportional to the instantaneous power for meter calibration. They include two 16-bit, delta-sigma ADCs for a wide range of IB and IMAX currents and/or small shunt (< 200 µOhms) meter designs. It includes an ultra-low drift voltage reference with < 15 ppm/°C through a specially designed band gap temperature curve for the minimum gradient across the industrial temperature range. A fixed-function DSP block is on-chip for active (real) power calculation. Strong output drive for mechanical counters are on-chip to reduce field failures and mechanical counter sticking. A no-load threshold block prevents any current creep measurements. A Power-On Reset (POR) block restricts meter performance during low-voltage situations. These accurate energy-metering ICs with high field reliability are available in the industry- standard pinout.
