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 I B and I MAX 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.
Package Type
? Tamper output pin for negative power indication
? Industrial Temperature Range: -40°C to +85°C
? Supplies instantaneous active (real) power on
HF OUT for meter calibration
