Functional safety in high-temperature applications

The actuator and the drive electronics are often mounted directly on the transmission block and exposed to ambient temperatures as high at 150°C. Having the electronics function through these temperatures requires specially designed integrated circuits (ICs) that can withstand semiconductor junction temperatures as high as 175°C. Given the exponential dependence on temperature, designers must consider the mission profiles for these high-temperature applications carefully when assessing FIT rates. In order to meet these requirements, TI offers AEC-Q100 Grade 0 functional safety parts (identified with the designation “E” after the part number) that are designed and qualified for ambient temperatures up to 150°C and junction temperatures up to 175°C.
