TIDA-00892

Isolated RS-485 With Integrated Signal and Power Reference Design

TIDA-00892

Design files

Overview

The TIDA-00892 reference design provides a compact solution capable of generating isolated DC power while supporting isolated RS-485 communication. The design consists of a reinforced digital isolator with integrated power combined with an RS-485 communication transceiver.

Features
  • Small Combination Solution (Equal to ISOW7841 Device Footprint)
  • Single Power Supply Solution (No separate supply required for interface side)
  • Reduced BOM Cost
  • Extendable to Other Full-Duplex RS-485 Tranceivers
Industrial

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
