(1) Thermally limited by junction temperature, see Absolute Maximum Ratings. Applies when device mounted on TMCS1133xEVM. For more details, see the Safe Operating Area section.
(2) Lifetime and environmental drift specifications based on three lot AEC-Q100 qualification stress test results. Typical values are population mean+1σ from worst case stress test condition. Min/max are tested device population mean±6σ; devices tested in AEC-Q100 qualification stayed within min/max limits for all stress conditions. See Lifetime and Environmental Stability section for more details.
