CS5464

Three-channel, Single-phase Power/Energy IC

Features

Description

The CS5464 is an integrated power measure-

ment device which combines three ∆Σ

analog-to-digital converters, power calculation

engine, energy-to-frequency converter, and a

serial interface on a single chip. It is designed to

accurately measure instantaneous current and

• Energy Data Linearity: ±±0.1 ꢀo ꢁeaꢂing

ꢀver .±±±:. Dynamic ꢁange

• On-chip Functiꢀns:

- Instantaneous Voltage, Current, and Power

- I_RMSand V_RMS, Active, Reactive, and

Apparent Power

- Current Fault and Voltage Sag Detect

- System Calibrations / Phase Compensation

- Temperature Sensor

voltage and calculate V

power, active power, apparent power, and reac-

tive power for high-performance power

measurement applications.

- Energy-to-pulse Conversion

The CS5464 is optimized to interface to shunt re-

sistors or current transformers for current

measurement, and to resistive dividers or poten-

tial transformers for voltage measurement.

- Positive-only Accumulation Mode

• Meets Accuracy Spec oꢀr IEC, ANSI, & JIS

• Lꢀw Pꢀwer Cꢀnsumptiꢀn

• Tamper Detectiꢀn in 2-Wire Distributiꢀn

Systems

• GND-reoerenceꢂ Signals with Single Supply

• On-chip 205 V ꢁeoerence (25 ppm/°C typ)

• Pꢀwer Supply Mꢀnitꢀr

The CS5464 features a tamper detection

scheme that uses the larger of the active power

measurements to register energy. Additional fea-

tures

include

system-level

calibration,

temperature sensor, voltage sag & current fault

detection, and phase compensation.

• Simple Three-wire Digital Serial Interoace

• “Autꢀ-bꢀꢀt” Mꢀꢂe orꢀm Serial E PꢁOM0

• Pꢀwer Supply Cꢀnoiguratiꢀns
