CS5466

Low Cost Power/Energy IC with Pulse Output

Features

Description

The CS5466 is a low cost power meter solution combin-

ing two ∆Σ Analog-to-Digital Converters (ADC)’s, an

energy-to-frequency converter, and energy pulse out-

puts on a single chip. It is designed to accurately

measure and calculate energy for single phase 2- or 3-

wire power metering applications with minimal external

components.

Single Chip; Power Measurement Solution

Energy Data Linearity: 0.1% of Reading

over 1000:1 Dynamic Range

On-Chip functions: Measures Energy and

Performs Energy-to-Pulse Conversions

Meets Accuracy Spec for IEC 687/1036

High Pass Filter Option

Four Input Ranges for Current Channel

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

Pulse Outputs for Stepper Motor or

Mechanical Counter

On-Chip Energy Direction Indicator

Ground Referenced Input Signals with Single

Supply

Low frequency energy outputs, E1 and E2, supply aver-

age real power and can be used to drive a stepper motor

or a mechanical counter; the high frequency energy out-

put FOUT can be used for calibration; and NEG indicates

negative power.

The CS5466 has configuration pins which allow for direct

configuration of pulse output frequency, current channel

input range, and high pass filter enable option.

The CS5466 also has a power-on reset function which

holds the part in reset until the supply reaches an oper-

able level.
