The DRV8351-SEP HDR exposure was performed on biased and unbiased devices in a Co-60 gamma cell at a TI facility in Dallas, Texas. The unattenuated dose rate of this cell is 177.47rads(Si) / s. After exposure, the devices were packed in dry ice (per MIL-STD-883 Method 1019.9 section 3.10) and full post radiation electrical evaluation using Texas Instruments ATE was conducted. ATE test limits are set per data sheet electrical limits based on qualification and characterization data. Post radiation measurements were taken within 30 minutes of removing the devices from the dry ice container. The devices were allowed to reach room temperature prior to electrical post radiation measurements.
