The designers of automotive electronics face many technical challenges during the system design process, including designing methods of protection against a variety of electrical hazards. The three major sources of electrical hazards in these systems are electrostatic discharge (ESD), lightning, and switching loads in power electronics circuits. This application note from Littelfuse looks at how overcoming transient surges that can harm a vehicle’s electronics is one of the biggest challenges of the design process.
Protecting automotive electronics includes eliminating transient surges that can damage the control units, infotainment electronics, sensors, fuel injectors, valves, motors, 12/24/42/48V powertrains and hydrolytic controllers, etc.
