TIDA-01230

Isolated RS-232 With Integrated Signal and Power Reference Design

TIDA-01230

Design files

Overview

The TIDA-01230 reference design provides a compact solution capable of generating isolated DC power while supporting isolated RS-232 communication. The design consists of a reinforced digital isolator with integrated power combined with an RS-232 communication transceiver.

Features
  • Small Combination Solution (Slightly Larger than ISOW7842 Device Footprint)
  • Single Power Supply Solution (No separate supply required for interface side)
  • Reduced BOM Cost
  • Extendable to Other RS-232 Tranceivers
Industrial

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