CS5484

Four Channel Energy Measurement IC

Features & Description

Description

•

Superior Analog Performance with Ultra-low Noise Level

and High SNR

Energy Measurement Accuracy of 0.1% over 4000:1

Dynamic Range

The CS5484 is a high-accuracy, four-channel, energy

measurement analog front end.

The CS5484 incorporates independent 4^thorder Delta-Sigma

analog-to-digital converters for every channel, reference

circuitry, and the proven EXL signal processing core to provide

active, reactive, and apparent energy measurement. In

addition, RMS and power factor calculations are available.

Calculations are output through a configurable energy pulse,

or direct UART/SPI™ serial access to on-chip registers.

Instantaneous current, voltage, and power measurements are

also available over the serial port. Multiple serial options are

offered to allow customer flexibility. The SPI provides higher

speed, and the 2-wire UART minimizes the cost of isolation

where required.

Current RMS Measurement Accuracy of 0.1% over 1000:1

Dynamic Range

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

for Voltage and Current Measurements

4 Configurable Digital Outputs for Energy Pulses,

Zero-crossing, or 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

Overcurrent, Voltage Sag, and Voltage Swell Detection

Ultra-fast On-chip Digital Calibration

Internal Register Protection via Checksum and Write

Protection

UART/SPI™ Serial Interface

On-chip Temperature Sensor

On-chip Voltage Reference (25ppm/°C Typ.)

Single 3.3V Power Supply

Ultra-fine Phase Compensation

Low Power Consumption: <13mW

Power Supply Configurations

- GNDA = GNDD = 0V, VDDA = +3.3V

5mmx5mm 28-pin QFN Package

Four configurable digital outputs provide energy pulses,

zero-crossing, energy direction, and interrupt functions.

Interrupts can be generated for a variety of conditions

including voltage sag or swell, overcurrent, and more. On-chip

The CS5484 is designed to interface to a variety of voltage and

current sensors including shunt resistors, current

transformers, and Rogowski coils.

•

On-chip functionality makes digital calibration simple and

ultra-fast, minimizing the time required at the end of the

customer production line. Performance across temperature is

ensured with an on-chip voltage reference with low drift. A

single 3.3V power supply is required, and power consumption

is low at <13mW. To minimize space requirements, the

CS5484 is offered in a low-cost, 5mm x5mm 28-pin QFN

package.
