ESD Protection of USB 2.0 Interfaces

Posted by Anindita Bhattacharya on 17 August 2020

Two decades ago, communication between a host computer and other devices was a complex and difficult task. The Universal Serial Bus (USB) was developed by a group of companies in 1994 to replace the multiple slow buses with a single bus that could exchange data between the host system and the peripherals. Following its release, USB quickly became very popular due to its ease of use and fast data transfer rate.

Think about a situation when you ordered merchandise online and you were eagerly expecting this package. Each day you watched through your window for the delivery truck to arrive, but unfortunately, it ended up arriving later than expected. In such a case, you would have benefited from a tracking system via your phone or computer. Then, you could know exactly when your package would arrive. Or think about another situation, when your child is picked up from school by the after-school service provider and you wonder if he or she has reached the destination safely.
