SLVK181 January 2025 DRV8351-SEP
The purpose of this study was to characterize the effect of heavy-ion irradiation on the single-event effect (SEE) performance of the DRV8351-SEP 40V Three Phase Half-Bridge Gate driver. Heavy-ions with LETEFF =20 to 48MeV × cm2 / mg were used for the SEE characterization campaign. Flux of approximately 105 ions / cm2 × s and fluences of approximately 107 ions / cm2 per run were used for the characterization. The SEE results demonstrated that the DRV8351-SEP exhibits cross confuction events that are explained in more detail in the sections above. The cross conduction events did not seem to damage the device or the MOSFETS. SEL and SEB LETEFF = 48MeV × cm2 / mg and across the full electrical specifications. Transients at LETEFF = 48MeV × cm2 / mg on GL/GH/SH are presented and discussed. CREME96-based worst week event-rate calculations for LEO(ISS) and GEO orbits for the DSEE and SET are presented for reference.
