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