High-voltage transients in automotive and industrial systems are common and can last from microseconds to hundreds of milliseconds, sending significant energy downstream.
Transient causes include automotive load dumps and spikes caused by load steps and parasitic inductance. To avoid the risk of failure, all electronics in these systems must either be robust enough to directly withstand the transient energy spikes, or they must be protected from them.
Read this article to learn about Analog Devices’ LT4356 surge stopper, which delivers a dramatic performance upgrade over traditional, passive clamp protection techniques. It actively protects downstream components from overvoltage by regulating the gate of a pass MOSFET and it limits current with the help of a standard sense resistor.
