Wachutka 1) 1) Institute for Physics of Electrotechnology, Munich University of Technology, Arcisstraße 21, D-80333 Munich, Germany In electronics, a latch-up is a type of short circuit which can occur in an integrated circuit (IC). More specifically, it is the inadvertent creation of a low-impedance path between the power supply rails of a MOSFET circuit, triggering a parasitic structure which disrupts proper functioning of the part, possibly even leading to its destruction due to overcurrent. A power cycle is required to correct this situat…
