The automotive environment is indeed a unique environment. What is commonplace in automotive, no consumer product can survive, so all our semiconductors must work over a broad range of temperature—typically from –40 to +125°C—and typically the devices are lower power and have stringent ESD/EMI requirements. If they get a failure in a car, it is nearly a catastrophe. Everything has to work in automotive. That puts a lot of constraints on an electrical system. They are not sloppy constraints either, because as you connect all the electronic components together, you get a lot of tolerance-stack issues that don't allow you to be very sloppy. Jack Morgan
