Overview

The TIDA-00730 is an reference design examining how to protect an RS-485 bus against leathal transient waveforms such as IEC ESD, IEC EFT, and IEC surge. The reference design shows the level of protection that can be achieved through the implementation of a TVS diode on the bus lines of a standard RS-485 transcever as well as a RS-485 tranceiver with integrated IEC protection.

Features
  • Board Level IEC ESD Evaluation
  • Easy control of transceivers logic I/O pins
  • PAD Site Evaluation Of Multiple TVS Diode Structures
  • Series Pulse Proof Resistor Pads
  • General Purpose Evaluation Module For Half-Duplex RS-485 Transceivers

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