7.1 Single-Event Latch-up (SEL) Results

During the SEL testing the device was heated to 125°C by using a Closed-Loop PID controlled heat gun (MISTRAL 6 System (120V, 2400W). The temperature of the die was verified using thermal camera prior to exposure to heavy ions.

The species used for the SEL testing was Homium (165Ho at 15MeV / nucleon). For the 165Ho ion an angle of incidence of 0° was used to achieve an LETEFF = 75MeV × cm2 / mg (for more details, see Ion LETEFF, Depth, and Range in Silicon). The kinetic energy in the vacuum for this ions is 2.474GeV. Flux of approximately 105 ions / cm2× s and a fluence of approximately 107 ions / cm2 per run was used. Run duration to achieve this fluence was approximately two minutes. The four devices were powered up and exposed to the heavy-ions using the maximum recommended input voltage and boot voltage of 14V. The ASW (High-Side Driver Signal Return) was set to 150V with respect to AGND (low-side driver signal return). The device was set in both PWM and IIM modes during testing. For more information see Single-Event Effects section. No SEL events were observed during all nine runs, indicating that the TPS7H60x3-SP is SEL-free up to 75MeV × cm2 / mg. Table 8-4 shows the SEL test conditions and results. Figure 7-1 shows a plot of the current versus time for run 1.

Using the MFTF method shown in Single-Event Effects (SEE) Confidence Interval Calculations and combining (or summing) the fluences of the four runs at 125°C (4 × 107), the upper-bound cross-section (using a 95% confidence level) is calculated as:
