The JTAG interface is a type of interface used for downloading programs, and it is also frequently connected and disconnected while powered. It is well-known that hot-plugging can inevitably generate some surges or ESD (Electrostatic Discharge). Therefore, if protective measures are not taken, it is easy for surge ESD to break down the JTAG-related pins, … Read more
To ensure the stability of industrial bus communication, engineers usually consider circuit solutions for lightning protection, surge protection, and overvoltage protection during the design phase. Today, we will introduce some effective bus surge protection solutions. The Impact of Surges on Circuits Surges include surge current and surge voltage, which refer to the phenomenon where voltage … Read more
ESD: Electro-Static Discharge refers to the release of static electricity. Static electricity is a natural phenomenon that usually occurs through contact, friction, or induction between electrical devices. It is characterized by long-term accumulation, high voltage (which can reach thousands or even tens of thousands of volts), low charge, small current, and a short duration of … Read more
