CS5462

Low Cost Power/Energy IC with Pulse Output

Features

Description

The CS5462 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

On-Chip System Calibration Option

High Pass Filter Option for Both I and V

2 Available Current Input Ranges

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

Pulse Outputs for Stepper Motor or

Mechanical Counter

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 CS5462 has configuration pins which allow for direct

configuration of pulse output format, pulse output fre-

quency, current channel input range, high pass filter

option, and on-chip calibration.

On-Chip Energy Direction Indicator

Ground Reference Input Signals with Single

Supply

High Frequency Output for Calibration

On-Chip Power-on Reset

The CS5462 also has a power-on reset function which

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

able level.

Power Supply Configurations:

VA+ = +5 V; AGND = 0 V; VD+ = +3.3 V to 5 V
