CS5461A

Single Phase, Bi-directional Power/Energy IC

Features

Description

• Energy Data Linearity: ±±0.1 of Reading over

.±±±:. Dynamic Range

The CS5461A is an integrated power measure-

ment device which combines two ∆Σ

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

, instanta-

RMS

neous power, apparent power, and active power

for single-phase, 2- or 3-wire power metering

applications.

- System Calibrations and Phase Compensation

- Temperature Sensor

- Voltage Sag Detect

The CS5461A is optimized to interface to shunt

resistors or current transformers for current mea-

surement, and to resistive dividers or potential

transformers for voltage measurement.

• Meets Accuracy Spec for IEC, ANSI, & JIS0

• Low Power Consumption

• Current Input Optimized for Sense Resistor0

• GND-referenced Signals with Single Supply

• On-chip 205 V Reference (25 ppm/°C typ)

• Power Supply Monitor

The CS5461A features a bi-directional serial in-

terface for communication with a processor, and

a programmable energy-to-pulse output func-

tion. Additional features include on-chip

functionality to facilitate system-level calibration,

temperature sensor, voltage sag detection, and

phase compensation.

• Simple Three-wire Digital Serial Interface

• “Auto-boot” Mode from Serial E²PROM0

• Power Supply Configurations:
