Digitally Isolated 2-Channel, Wide DC Binary Input Module Reference Design

Overview

TopologyFlyback Converter
Input voltage3.3 V
Switching frequency3700-6300 kHz
IC revisionA

Description

This reference design enables translation of high DC voltage inputs upto 300VDC into binary logic level voltages that a typical electronic circuit can handle. This solution is very flexible, not only handling input voltages from 18 to 300VDC but also allowing programmable switching thresholds to set binary levels. In addition, this solution enables < ± 3.0% (± 1V measured value step size) error in voltage detection coupled with reliable isolation > 2kV RMS.

Features

Remark: BOM is added with main pdf.High accuracy voltage measurement capability (< ±3% error)Flexible solution handling input voltages from 18V to 300VDCMCU enables programmable switching thresholdsExcellent long term reliability with digital isolation includedProvides option for wetting current controlOutput can be either I2C or digital output
