Description
The MCP3905A/05L/06A 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. The MCP3905L offers reduced pulse width
of calibration output frequency and mechanical counter
drive for lower power meter designs. 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 fixedfunction DSP block is on-chip for active real-power
calculation. A no-load threshold block prevents any
current creep measurements. A Power-On Reset
(POR) block restricts meter performance during lowvoltage situations. These accurate energy metering ICs
with high field reliability are available in the industry
standard pinout.
