The power supply of an ECU

How does the power supply of an ECU work?

October 31, 2021 Dan Florian Alx Articles, General knowledge 2 comments

Reading time: 3 minute The power supply supplies power to all other units on the ECU. In a car, the available voltage source is the battery, which in operation has terminals 13.5 - 14V. This voltage value can vary depending on several factors. Every functional block needs constant voltage to function properly.

  • Marius B. on Top 10 resistors for harsh environments
    Alex, if I remember correctly, I've had this discussion before. Yes, IPRS has manufactured components in 5 classes. Aerospace, nuclear, military, and research
  • Balauta M. on Top 10 resistors for harsh environments
    Add, thyristors for ASEA SWEDEN. There are other destinations, for military use only. Thanks for the additions, I have some of the information
  • Alexander I. on Top 10 resistors for harsh environments
    Microwave power components (ICCE), microprocessors.
  • Dan Florian Alx on Top 10 resistors for harsh environments
    Interesting. These embassies / exchanges are still practiced today. I would be curious to know which were the most expensive custom components delivered externally.
  • Alexander I. on Top 10 resistors for harsh environments
    Yes, the terminal holder on which the chips were mounted, the housing or the closing cover, etc.
