LoRaWAN® Gateways Need Robust ESD and Overvoltage Protection

Posted by Tim Puls on 10 February 2020

Gateways featuring Semtech’s LoRa® devices often reside in electrically harsh industrial environments. As the centerpiece for a LoRaWAN® network, these gateways need to operate in the field for many years. The longevity of the network requires that gateways be immune to a range of transient threats the equipment may encounter over its lifetime. As such, gateway data ports need to be safeguarded from overvoltage transient threats, including electrostatic discharge (ESD), electrical fast transients (EFT) and lightning surge.

Transient Protection of RS-485 Buses in Industrial Applications

Posted by Bill Russell on 04 February 2020

Modern industrial networks rely on robust RS-485 communication links for long distance data transmission. These networks operate in harsh electromagnetic environments and must be capable of withstanding electrical overstress (EOS) events without damage. Semtech’s Protection Products Group application engineering team recently had the opportunity to work with Renesas Corporation engineers on a reference design for protecting Renesas’ fault-protected RS-485 transceivers, used in industrial applications.
