One article talks with transparent electrostatic discharge (ESD) protection

I have always wanted to tell you about the theory of ESD, which is classic. However, because the theoretical is too strong, any theory is one by one. If you do not draw eggs, you will not draw David. Let's talk about what is the electrostatic discharge (ESD: Electrostatic Discharge)? This should be the main culprit that causes all electronic components or integrated circuit systems to cause excessive electrical stability destruction. Because the electrostatic voltage is usually very high (u003e thousands of volts), this damage is devastating and permanent, which will cause the circuit to burn directly. So preventing static damage is the number one problem for all IC design and manufacturing. Static electricity is usually produced by artificially, such as production, assembly, testing, storage, and transportation.

After disassembling 131 models of nitride, we got 8 important data

In recent years, Nitride has gradually entered the system from the original third -party brand accessories, becoming the standard for many mobile phones and laptops. At the same time, the application field of nitride technology in the consumer power supply market has also been expanded. From a single fast charger, it gradually extends to fast charging docking docks, fast charging plug -in boards, fast -charging wall plugs and other categories. In this process, nitride has gradually changed from the initial black technology to a well -known technology. The charging head network has disassembled nearly 2,000 consumer power supply accessories, including more than 100 cases of nitrogen -related fast charging products. In the dissection of product dissection again and again, the product is true, providing a wealth of cases and design references for the friends of the fast -charged power engineer, and promoting the development of nitride the fast -charging industry.

MEMS Silicon Crystal Vibration Replaces the six major advantages of Mentai to solve the pain point of electronic engineers

Introduction: In the continuous expansion of time scene applications, electronic systems have put forward higher and more complex technical requirements for timing components, and traditional quartz crystals cannot overcome their inherent restrictions. , Limited frequency and other disadvantages. It can no longer meet the needs of all application areas. Compared with quartz crystal, MEMS Silicon Crystal Vibration will have the opportunity to replace traditional quartz crystal with the advantages of non -stop vibration, not running, not afraid of falling, no warm drift, and small -volume programming. I love the original MEMS application topic, bringing together the advantages of the six major MEMS projects to help engineers deeply understand MEMS crystal products, technology, alternative cases, and recommended applications. This topic is supported by the original and agents.

What is Hall effect (Hall)? Hall effect sensor work principle analysis

Integrated circuit (Hall Effect IC), Hall Effect Sensor IC, Hall Sensor, Hall circuit, Hall IC. Hall is sometimes translated into Huo Er, so it can also be called Huo Er integrated circuit. The following is referred to as Hall IC. Hall IC is usually divided into digital Hall IC and linear Hall IC according to the output signal type. Digital Hall IC controls the output or turn off through the strong and weakness of the external magnetic field. It is similar to the function of switching, so it is often called the switch -type Hall IC. The linear Hall IC output is an analog signal. The strength of the output voltage and the external magnetic field is usually linear. Switch -type Hall IC is often divided into single -level Hall IC

Why is the power MOS tube burned? Come in and see!

The working status of MOS in the controller circuit: the process of opening (from the transition process from the deadline), the transition status, the process of turning off (from the transition process from the diversion to the deadline), and the deadline. The main loss of MOS also corresponds to these states, switching loss (opening process and turning off process), turning losses, interception loss (caused by leakage current, this neglect), and avalanche energy loss. As long as these losses are controlled within the MOS to bear the specifications, MOS will work normally, exceeding the tolerance range, that is, damage. And switching loss is often greater than the leading state loss, and the gap between different MOS may be very large. The main cause of MOS damage: overcurrent ---------- continuous large current or instant large current

Deep analysis! Power semiconductor on the car (2)

The power-driven system is mainly used in the inverter DC-AC, and the DC electricity conversion of the charging battery 12V is converted into an AC electric drive motor of the drive motor 220V. Dozens of IGBTs need to be used on the motor control system. After output high voltage from the battery, it needs to be changed to low voltage through DC-DC for low-voltage networks. For example There are 84 IGBTs, 12 IGBTs of other motors, and Tesla used a total of 96 IGBT. The electrical control system is the second largest single component of the value of electric vehicles. The cost of electrical control procurement in a single electric vehicle is about 3,000-5000 yuan. Among them, IGBT accounts for 41%of the electronic control cost. It is the core component of the electronic control. Complete

It's time to understand oxidation

In the IEEE SPECTRUM Chinese version of "Science and Technology Observation" in May 2002, the late Lester F. East-Man and Umesh K.Mishra (Umesh K.Mishra) Speaking of a bold technology in the power semiconductor industry at the time: Nitride (GAN). They expressed an optimistic view on the prospects of the emerging broadband wireless network, radar and power switching applications in the emerging broadband wireless network, radar, and power grid at that time. They claimed that nitride device was "the strongest and durable transistor so far." Isman and Mishra are right. The broadband gap of nitride (the energy of the restraint electrons and the energy that helps to conduct) and other properties allow us to use this material
