Abstract :
The analysis of four self switch-off events in the power supply on-board ESA´s SOHO satellite point strongly in the direction of being cosmic ray or proton induced. Detailed analysis of the relevant power supply schematics identified a number of analog IC´s capable of causing or contributing to such events. This paper details the effort taken in order to characterise the upset sensitivity of the various analog IC´s flown. Testing aspects and Single Event Transient (SET) results are presented. Ground testing, simulating the flight conditions, were carried out at both heavy ion and proton accelerators
