Overview

This reference design is designed to measure only branch current and is created for accuracy across the majority of the rated current range while at the same time being cost efficient. This is achieved by using a highly integrated SoC device which has up to 7 channels of the 24bit Delta-Sigma ADCs available for current measurement. This solution also has several options for communication supported. such as UART, JTAG, etc. Applications include load management, sub-panels, etc.

Features

Precise current measurement through 7 channels of Delta-Sigma ADCs (< 2% from 10% to 100% of rated current, controlled by CT & burden resistor)
Voltage measurement enabled with integrated SAR ADC
Extended temperature range operability of -40C to +125C
Integrated single chip solution results in a cost and area efficient solution
Large MSP Family & Roadmap / Scale performance, features, price
Metering library available in source for use on MSPs
