CS5480

Three Channel Energy Measurement IC

Features

Description

•

Superior Analog Performance with Ultra-low Noise Level & The CS5480 is a high-accuracy, three-channel, energy mea-

High SNR

surement analog front end.

Energy Measurement Accuracy of 0.1% over 4000:1

Dynamic Range

The CS5480 incorporates independent, 4^thorder, Delta-Sigma

analog-to-digital converters for every channel, reference cir-

cuitry, and the proven EXL signal processing core to provide

active, reactive, and apparent energy measurement. In addi-

tion, RMS and power factor calculations are available.

Calculations are output via configurable energy pulse, or direct

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

Current RMS Measurement Accuracy of 0.1% over 1000:1

Dynamic Range

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

for Voltage and Current Measurements

3 Configurable Digital Outputs for Energy Pulses,

Zero-crossing, or Energy Direction

Supports Shunt Resistor, CT, & 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

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.

Three 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 register integrity

is assured via checksum and write protection. The CS5480 is

designed to interface to a variety of voltage and current sen-

sors including shunt resistors, current transformers, and

Rogowski coils.

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

On-chip functionality makes digital calibration simple and ul-

tra-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 very low drift.

A single 3.3V power supply is required, and power consump-

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

the CS5480 is offered in a low-cost, 4mm x 4mm 24-pin QFN

package.

Ultra-fine Phase Compensation

Low Power Consumption: <13mW

Power Supply Configurations

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