- Parasitic state in a chip that doesn't reach full short-circuit but draws infinite current ⟶ drains the battery.


Parasitic state in a chip that doesn't reach full short-circuit but draws infinite current ⟶ drains the battery.

Triggered by overvoltage: electromagnetic pulse ⟶ copper traces act as antennas ⟶ voltage spike ⟶ parasitic thyristor locks on.

Critical concern in aerospace; airplanes are exposed to radiation and electromagnetic interference that can trigger latch-up in unshielded electronics.
