Other Parts Discussed in Thread: THVD1550, THVD1419, THVD2450
Hi Team,
We had used the RS-485 Transceivers ( THVD1500DR) IC in our project. We had used the series resistors(10 ohm) and ESD diodes in A & B ports that ends to connector. While using in the client location the series resistors, ESD diodes and Transceiver IC were burned.
What will be possible conditions for this to happen? Can you help us in debugging this issue?
In some boards series resistors only burned , ESD protection diodes were not burned.
I have attached the schematics section of RS 485 in our boards.
