TIDA-060027 Reference Design

Texas Instruments

Protecting RS-485 transceivers from sustained high voltage/electrical over-stress reference design

Description

This reference design proposes an implementation of combining Positive Temperature Coefficient (PTC) fuses and Silicon Diode Alternating Current (SIDAC) devices to keep the transceivers alive under sustained exposure to high voltage. It highlights the capability of this particular protection device combination for RS-485 transceivers.
