Evil-smelling smoke, fire and woe. Or just "pffffft!"Hi everyone, i started a project that includes regulating a voltage down to 5v.
I'm using the ST LM317 the input voltage must be lower than 36v, what happens if it is higher than that ?
You see a lot of this in automotive modules. Especially the ignition drivers.I have seen chips cratered from pureline voltage applied to them back when I was in tech school, It was a 741 someone accidentally hooked up to line voltage. If you are interested I'll tell more of the story. The silicon under the epoxy was completely vaporized.just a conical crater in the package was left.
Do you see a lot of automotive systems that had been abused with line voltage (120-240Vac based on your location) instead of 12Vdc?You see a lot of this in automotive modules. Especially the ignition drivers.View attachment 176609
Can't say I have ever seen that. For things related to this topic its either from the ignition coils, hooking 12v systems in to 24v, a short in wiring or the alternator/regulator over charging .Do you see a lot of automotive systems that had been abused with line voltage (120-240Vac based on your location) instead of 12Vdc?
