In China, cars are basically standardized products when they leave the factory. In order to meet the personalized and diversified needs of car owners, there is a huge "car aftermarket", namely 4S stores, maintenance stations, and modification plants, where automobile enthusiasts can modify or add some products into the……

The Asian Edition of Bloomberg News published at 8:00 GMT on October 19, 2022, an article “China’s Underground Market of Chips Draws Desperate Automakers”, an article about new energy vehicles, Huaqiangbei chip trade of “The No.1 Business Street of Electr

We know that when the sub -modules of the circuit system are transferred to data exchange, there may be some problems that cause the signal to "circulate" the signal that the signal cannot be normal and high quality. The types of their respective signals are inconsistent (such as sensor detection signal), etc. At this ……

Today I said a voltage PWM controller, which is the LM5025 chip. Let's take a look at its basic parameters. Basic features: The chip built -in startup bias regulator, which has a programmable low -voltage lock output function (UVLO), voltage drive, 5V reference voltage, programmable soft startup function, and heat -cut……

The full name of TVS is Transient Voltage Suppressor, a transient voltage suppressor, which is a protective device. The tvs tube also belongs to the diode, but the characteristics are different from the diode. Its working principle is similar to the stabilization diode. It also uses reverse breakdown stable voltage. Wh……

Some transistors are more than 50 billion, and these transistors are 10,000 times smaller than human hair. They are made on the huge super -clean cleaning plant floor, which can reach seven floors height, and the length is equivalent to four football fields. Micro -chip is the lifeblood of the modern economy in many as……

Nowadays, "end -to -end\\ When the mobile phone calls is turned on, the human voice will be picked up by the mobile phone microphone to become a electrical signal. This electrical signal is an analog signal, and we can also call it the original signal. At this time, the sound wave (mechanical wave) was converted into a……

Integration (Integration) refers to the process of gathering different units and achieving specific functions, integrating multiple people's activities, not naturally. Integrated circuits and system integration are relatively common terms. This article analyzes modern electronic integration technology around the integr……

1. Forewords With the significant acceleration of electric vehicles in the market, the differences between brands, market segments and models are also increasin……

To improve the efficiency of the switching power supply in the main loss of the switching power supply, it is necessary to distinguish and roughly estimate the various losses. The loss inside the switching power can be roughly divided into four aspects: switching loss, conducting loss, additional loss and resistance lo……

This article introduces the design ideas of the motor controller IGBT module driving circuit, explains the characteristics of the IGBT module, the design and protection of the gate -drive circuit, and the current, voltage, and temperature protection of the IGBT module in normal operation. And provide corresponding desi……

The Boost circuit is a type of switch DC voltage voltage, which can make the output voltage higher than the input voltage. It is a more common circuit design in electronic circuit design. This article will introduce the basic principles and circuit parameter design to you. First of all, we need to know: capacitors hind……
