CS5460A

Single Phase, Bi-directional Power/Energy IC

Features

Description

The CS5460A is a highly integrated power mea-

surement solution which combines two ∆Σ

Analog-to-digital Converters (ADCs), high-speed

power calculation functions, and a serial interface

on a single chip. It is designed to accurately mea-

sure and calculate: Real (True) Energy,

Instantaneous Power, I_RMS, and V_RMSfor single

phase 2- or 3-wire power metering applications.

The CS5460A interfaces to a low-cost shunt resis-

tor or transformer to measure current, and to a

resistive divider or potential transformer to mea-

sure voltage. The CS5460A features

bi-directional serial interface for communication

with a microcontroller and a pulse output engine for

which the average pulse frequency is proportional

to the real power. The CS5460A has on-chip func-

tionality to facilitate AC or DC system-level

calibration.

z Ground-Referenced Signals with Single

Supply

z On-chip 2.5 V Reference (MAX 60 ppm/°C

drift)

The “Auto-boot” feature allows the CS5460A to

function ‘stand-alone’ and to initialize itself on sys-

tem power-up. In Auto-boot Mode, the CS5460A

reads the calibration data and start-up instructions

from an external EEPROM. In this mode, the

CS5460A can operate without a microcontroller, in

order to lower the total bill-of-materials cost.
