Overview: In this seminar we will take a look at some Automotive Applications, the high temperatures they are submitted and how the operation under these conditions degrades the system energy efficiency and reliability.
Furthermore we will show the importance of high accurate temperature monitoring to guarantee high energy efficiency and reliability in Automatic Gearbox Systems. At the end of the seminar we will present a digital temperature sensor developed for automotive applications operating under extreme temperatures: the LM95172QA.
