CS5460

Single Phase Bi-Directional Power/Energy IC

Features

Description

The CS5460 is a highly integrated ∆Σ Analog-to-Digital

Converter (ADC) which combines two ∆Σ ADCs, high

speed power calculation functions, and a serial interface

on a single chip. It is designed to accurately measure

and calculate: Energy, Instantaneous Power, I_RMS, and

l Energy Data Linearity: 0.1% of Reading over

1000:1 Dynamic Range

l On-Chip Functions: Energy, I V,

and V

, Energy to Pulse-Rate

RMS

Conversion

_RMSfor single phase 2 or 3-wire power meter applica-

tions. The CS5460 interfaces to a low cost shunt or

transformer to measure current, and resistive divider or

transformer to measure voltage. The CS5460 features a

bi-directional serial interface for communication with a

micro-controller and a fixed-width programmable fre-

quency output that is proportional to energy. The product

is initialized and fully functional upon power-up, and in-

cludes facilities for system-level calibration under control

of the user program.

l Complies with IEC 687/1036, JIS

l Power Consumption <12 mW

l Interface Optimized for Shunt Sensor

l Phase Compensation

l Ground-Referenced Signals with Single

Supply

l System Calibration

l On-chip 2.5 V Reference (60 ppm/°C drift)

l Simple Three-wire Serial Interface

l Watch Dog Timer

l Power Supply Monitor

l Power Supply Configurations

- VA+ = +5 V; VA- = 0V; VD+ = +3 V to +5 V

- VA+ = +2.5 V; VA- = -2.5 V; VD+ = +3 V
