Two Channel Energy Measurement IC

Features & Description

Description

The CS5490 is a high-accuracy, two-channel, energy measure-

ment analog front end.

•

Superior Analog Performance with Ultra-low Noise Level &

High SNR

Energy Measurement Accuracy of 0.1% over a 4000:1

Dynamic Range

Two Independent 24-bit, 4^th-order, Delta-Sigma

Modulators for Voltage and Current Measurements

The CS5490 incorporates independent 4^thorder Delta-Sigma an-

alog-to-digital converters for both channels, reference circuitry,

and the proven EXL signal processing core to provide active, re-

active, and apparent energy measurement. In addition, RMS and

power factor calculations are available. Calculations are output

via a configurable energy pulse, or direct UART serial access to

on-chip registers. Instantaneous current, voltage, and power

measurements are also available over the serial port. The

two-wire UART minimizes the cost of isolation where required.

Configurable Digital Output for Energy Pulses, Interrupt,

zero-crossing, and Energy Direction

Supports Shunt Resistor, CT, and Rogowski Coil Current

Sensors

On-chip Measurements/Calculations:

- Active, Reactive, and Apparent Power

- RMS Voltage and Current

- Power Factor and Line Frequency

- Instantaneous Voltage, Current, and Power

A configurable digital output provides energy pulses, zero-cross-

ing, energy direction, or interrupt functions. Interrupts can be

generated for a variety of conditions including voltage sag or

swell, overcurrent, and more. On-chip register integrity is assured

via checksum and write protection. The CS5490 is designed to in-

terface to a variety of voltage and current sensors, including shunt

resistors, current transformers, and Rogowski coils.

•

Overcurrent, Voltage Sag, and Voltage Swell Detection

Ultra-fast On-chip Digital Calibration

Configurable No-load Threshold for Anti-creep

Internal Register Protection via Checksum and Write

Protection

On-chip functionality makes digital calibration simple and ultra

fast to minimize the time required at the end of the customer pro-

duction line. Performance across temperature is ensured with an

on-chip voltage reference with low drift. A single 3.3V power sup-

ply is required, and power consumption is low at <13mW. To

minimize space requirements, the CS5490 is offered in a low-cost

16-pin SOIC package.
