TPS7H500x-SP Single-Event Effects (SEE)

The purpose of this study is to characterize the single-event-effects (SEE) performance due to heavy-ion irradiation of the TPS7H500x-SP. Destructive single-event-effects (DSEE) performance was verified at the maximum recommended voltage of 14 V. SET performance was verified over a variety of different operating conditions including: internal and external clock, FSW = 1 and 2 MHz, error amp (in unity gain), and cross conduction. For the transient characterization, input voltages of 4, 12, and 14 V were used (For TPS7H5002/3/4- SP only a nominal VIN of 12V was used). Heavy-ions with LETEFF of 30.5 to 75 MeV·cm2/mg were used during the validation. A total of 11 devices were used for the data collection. Flux of ≈105 ions/cm2·s and fluences of ≈107 ions/cm2 per run were used for the characterization. The results demonstrated that the TPS7H500x-SP is SEL and SEB/SEGR free up to 75 MeV·cm2/mg, at T = 125°C and T = 25°C, respectively, and across the full electrical specifications. SET characterization is presented and discussed for a variety of different operating conditions.
