When I arrived at Fort Myer Airport in Florida last week, I showed a variety of classic cars from Ford. These Ford classic cars on the airport square have a history of nearly one hundred years and look elegant and elegant, especially the black iconic T-car with a portrait of real-life Henry Ford. This shiny T-type The car is a stunning work of a generation of mechanical engineering genius. But these centuries-old classic cars lack an element that we take for granted — electronic devices.
In stark contrast to a century ago, today's cars are stuffed with semiconductor products. The billions of transistors scattered over hundreds of integrated circuits are working so busy that today's cars are extremely advanced engineering products.
Even in front of us, we often overlook a large number of semiconductor devices in the car:
A large number of microcontrollers perform millions of floating-point operations to keep the vehicle running;
Sensors are embedded in various locations of the vehicle to collect and process complex information;
The motor driver is the control motor in the car, and the number is up to several dozen;
The RF chip is used to receive and sense signals, helping us to keep communication open, to achieve positioning, and to ensure safety;
Audio electronics can play our favorite songs, while videos let our children stay quietly in the back seat.
At the same time, these advanced systems also need to supply power at precise current and voltage. Modern cars are not just vehicles, they are better than sophisticated electronic networks. I have read the relevant introductions elsewhere, and there are nearly 10 billion transistors in a regular car.
With the rapid development of the automotive industry, automotive designers are also facing more challenges. Automotive systems are very complex and need to be designed to meet stringent safety and reliability standards. Semiconductor components in automobiles need to work in extremely harsh environments while still providing greater performance reliability. Selecting automotive-grade electronics from the millions of electronic devices currently available is also a very important task.
At TI, my job is to work hard to simplify the design process for all external engineers. I think we have achieved excellent WEBENCH® performance so far, which helps engineers quickly design a step-down power supply from 12V input to 3.3V output, such as designing a complex multi-rail FPGA system power supply. But one thing that needs to be improved is the design of the WEBENCH tool for cars only. So I have been working hard over the past 14 months to enhance our WEBENCH design tools for automotive applications. The current new product is the “WEBENCH Automotive Design Toolâ€, which helps you quickly design and prototype your automotive system. Not only do you get the same powerful tool suite that WEBENCH offers for commercial applications, but you can also focus on automotive electronics design. Still very convenient (if not, please tell me!):
Access, starting with the WEBENCH car panel;
Enter your conditions, such as 9V to 18V input, 3.3V output, and 2A output current;
View the car marquee;
Optimize cost, size and efficiency;
Choose among various analyses.
In order to show you the step-by-step process, I also created the first demo video, please click here.
I think the relevant parts in my next new car may have been designed using TI WEBENCH tools. I am very proud of this. If your next design uses the WEBENCH tool, please share your experience here. I really like to pay attention to the car, and I hope I can help you.
