Four-channel Power/Energy IC

Features

Description

• Energy Data Linearity: ±±0.1 of Reading over

.±±±:. Dynamic Range

The CS5467 is an integrated power measure-

ment device which combines four ∆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

- Current Fault and Voltage Sag Detect

- System Calibrations / Phase Compensation

- Temperature Sensor

- Energy-to-pulse Conversion

- Positive-only Accumulation Mode

voltage and calculate V

power, active power, apparent power, and reac-

tive power for high-performance power

measurement applications.

• Meets Accuracy Spec for IEC, ANSI, & JIS

• Low Power Consumption

The CS5467 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.

• GND-referenced Signals with Single Supply

• On-chip, 205 V Reference

The CS5467 also features system-level calibra-

tion, a temperature sensor, voltage sag & current

fault detection, and phase compensation.

• Power Supply Monitor

• Simple Three-wire Digital Serial Interface

• “Auto-boot” Mode from Serial E²PROM0

• Power Supply Configurations

ORDERING INFORMATION:

VA+ = +5 V; AGND = ± V; VD+ = +303 V to +5 V
