7.2 Single-Event Burnout (SEB) and Single-Event Gate Rupture (SEGR) Results
During SEB/SEGR testing, the device was tested at room temperature. The same test conditions, in terms of biasing and voltage levels, apply for SEB/SEGR as was used during the SEL testing. In the case of the SEB/SEGR the device was tested in the following state machine states:
- Disabled (SR_UVLO = 0V)
- All outputs are low (RESETx = Low and PWRGD = Low)
- Enabled (SR_UVLO = 1V)
- All outputs are high (RESETx = High and PWRGD = High)
For more configuration information, please refer to Table 6-1.
The device was also configured in the following 4 different operating modes. Table 8-5 showcases the operating modes used on the units during testing.
- MODE 0, WD SW
- MODE 0, WD Off
- MODE 1, WD SW
- MODE 1, WD Off

The results for 24 runs across 12 devices for SEB/SEGR are shown in Table 8-5. Over all 24 runs, none of the 12 units exhibited any SEB/SEGR failures, indicating the TPS7H3XX4-SP is SEB/SEGR free at 75 MeV·cm2/mg. Typical VIN current vs time plots for SEB/SEGR on and off runs are shown in Figure 7-5 and Figure 7-6. Typical VPULL_UPx current vs time plots for SEB/SEGR on and off runs are shown in Figure 7-3 through Figure 7-6.

Using the MFTF method described in Single-Event Effects (SEE) Confidence Interval Calculations application report, the upper-bound cross-section (using a 95% confidence level) is calculated as:
σSEB ≤ 1.54 × 10–8 cm2/device for LETEFF = 75 MeV·cm2/mg and T = 25°C.
