Patent ID: 7310211

Claim:
A system for performing a method for suppressing latch-ups occurring in an electronic circuit wherein, in a current-limited supply voltage, an undervoltage is detected, the supply voltage is switched off following detection of a latch-up, and charge located in the circuit is reduced, said system protecting radiation-sensitive active circuit components of the electronic circuit, wherein the electronic circuit is subdivided into groups of active circuit components with substantially the same current consumption in a predefined area, and at least one of these groups of active circuit components with substantially the same current consumption in the predefined area has a protective circuit assigned to the electronic circuit, and wherein the protective circuit comprises a voltage controller adapted to be switched off and allowing for adjustment of a current limitation, an actuator, a comparator for detection of undervoltage, two monoflops, a short-circuiting switch with current limitation and, at an output, at least one capacitor.
