Infineon 1EDN7511B and 1EDN8511B Single Channel MOSFET Drivers

08.04.2019

Infineon introduced the new 1EDN7511B and 1EDN8511B EiceDRIVER gate drivers. These drivers are great for driving MOSFETs (OptiMOS families, CoolMOS, Superjunction MOSFETs, etc.) and IGBTs.

The 1EDN7511B and 1EDN8511B have LVTTL compatible differential inputs with an input voltage range of -5...+20V and are equipped with 4,2V and 8V UVLO protection.

The driver outputs are capable of delivering a maximum of 4 A of rise and fall of 8 A, and use a rail-to-rail stage to provide low impedance output channels (0,85 ohm and 0,35 ohm). The drivers have separate output channels for turning the transistor on and off.

The drivers have industry-leading reverse current resistance (up to 5A), eliminating the need for Schottky diodes on the outputs.

The drivers are available in a 6-pin SOT23-6 package.

Key Features:

output rise/fall current 4 A/8 A;
signal rise/fall time: 6 ns/5 ns;
signal propagation delay error: +- 5 ns;
undervoltage protection UVLO: 4 V and 8 V;
signal propagation delay: 19 ns;
input stability up to -10 V;
resistance to reverse output current up to 5 A.

Areas of use:

power factor correctors (DCM, CCM);
DC-DC converters;
switching power supplies;
synchronous rectification;
engine management;
wireless charger.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

France has begun developing hypersonic weapons 27.01.2019

France has joined the club of world powers developing so-called "hypersonic weapons" that fly several times faster than sound. After China, Russia and the United States, France is the fourth of the five permanent members of the UN Security Council to join the hypersonic race.

Hypersonic missiles are capable of maneuvering during flight, which makes them much more difficult to track and intercept at such a speed.

"We have decided to award a contract for a hypersonic glider" capable of flying at over 6000 kilometers per hour, French Defense Minister Florence Parly said last week. She promised that a test flight of the new weapon would be carried out by the end of 2021.

The minister noted that many countries are acquiring hypersonic weapons, and France "has the know-how to develop them." "We just can't afford to wait any longer," Ms. Parley said as she introduced the V-MaX project.
