Description
The CS5463 is an integrated power measure-
ment device which combines two
鈭單?/div>
analog-to-digital converters, power calculation
engine, energy-to-frequency converter, and a
serial interface on a single chip. It is designed to
accurately measure instantaneous current and
voltage, and calculate V
RMS
, I
RMS
, instanta-
neous power, apparent power, active power, and
reactive power for single-phase, 2- or 3-wire
power metering applications.
The CS5463 is optimized to interface to shunt re-
sistors or current transformers for current
measurement, and to resistive dividers or poten-
tial transformers for voltage measurement.
The CS5463 features a bi-directional serial inter-
face for communication with a processor and a
programmable energy-to-pulse output function.
Additional features include on-chip functionality
to facilitate system-level calibration, temperature
sensor, voltage sag detection, and phase
compensation.
