Abstract

The purpose of this study is to characterize the single-event-effects (SEE) performance due to heavy-ion irradiation of the TPS7H2140-SEP. SEE performance was verified at minimum (4.5 V) and maximum (32 V) operating conditions. Heavy-ions at an LETEFF of 48 MeV × cm2 / mg were used to irradiate three production devices and four pre-production devices. Flux of ≈105 ions / cm2 × s and fluences of ≈ 107 ions / cm2 per run were used for the characterization. The results demonstrated that the TPS7H2140-SEP is SEL and SEB/SEGR-free up to 48 MeV × cm2 / mg, at T = 125°C and T = 25°C, respectively, and across the full electrical specifications. SET performance for output voltage excursions ≥ |3%| from the nominal voltage, excursions ≥ |4%| from nominal CS, and negative edge transients on the FAULT pin are discussed in Single-Event Transients (SET).
