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,

Energy Data Linearity: 0.1% of Reading

sure voltage. The CS5460A features

bi-directional serial interface for communication

with a micro-controller and a pulse output engine

for which the average pulse frequency is propor-

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

functionality to facilitate AC or DC system-level

calibration.

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.
