Abstract

The purpose of this study is to characterize the single-event-effects (SEE) performance due to heavy-ion irradiation of the TPS7H4003-SEP. Heavy-ions with LETEFF of 48.2 MeV·cm2/mg were used to irradiate 3 production devices. Flux of ≈105 ions/cm2·s and fluence of ≈107 ions/cm2 per run were used for the characterization. The results demonstrated that the TPS7H4003-SEP is SEL and SEB/SEGR-free up to 48.2 MeV·cm2/mg, at T = 125°C and T = 25°C, respectively, and across the full electrical specifications. SET transients performance for output voltage excursions ≥ |3%| from the nominal voltage and PGOOD ≤ VIN – 0.5 V are presented and discussed.
