Description

The CS5467 is a watt-hour meter on a chip. It

measures line voltage and current and calcu-

lates active, reactive, apparent power, energy,

power factor, and RMS voltage and current.

An internal RMS voltage reference can be used

if

tampering.

Four ∆Σ analog-to-digital converters are used to

measure two voltages and two currents. Option-

ally, voltage2 channel can be used for

temperature measurement.

The CS5467 is designed to interface to a variety

of voltage and current sensors.

Additional features include system-level calibra-

tion, voltage sag and current fault detection,

peak detection, phase compensation, and ener-

gy pulse outputs.
