CS5461

Single Phase Bi-Directional Power/Energy IC

Features

Description

The CS5461 is an integrated power measure-

ment device which combines two ∆Σ ADCs, high

speed power calculation functions, and a serial

interface on a single chip. It is designed to accu-

rately measure Instantaneous Current and

Voltage, and calculate: Instantaneous Power,

z Energy Data Linearity: ±0.1% of Reading

z AC/DC System Calibrations

z Meets Accuracy Spec for IEC 687/1036, JIS

z Power Consumption <12 mW

z On-Chip Temperature Sensor

z Voltage Sag Detect

z Adjustable Input Range on Current Channel

z Phase Compensation

z GND-Referenced Signals with Single Supply

z On-chip 2.5 V Reference (25 ppm/°C typ)

z Simple Three-Wire Digital Serial Interface

z Power Supply Monitor

gle-phase 2- or 3-wire power metering

applications. The CS5461 can interface to a

low-cost shunt resistor or transformer for current

measurement, and to a resistive divider or poten-

tial transformer for voltage measurement. The

CS5461 features a bi-directional serial interface

for communication with a micro-controller and a

programmable energy-to-pulse output function.

CS5461 has on-chip functionality to facilitate AC

or DC system-level calibration. Additional fea-

tures include on-chip temperature sensor,

voltage sag detection, and phase compensation.

z Interface Optimized for Shunt Sensor

z Mechanical Counter/Stepper Motor Drive

z Smart “Auto-Boot” Mode from Serial

EEPROM with no microcontroller.
