Introduction to NTJD4001NT2G_TPC8209

The size of this internal resistance basically determines how much on-current the MOS tube chip can withstand (of course, it is related to other factors, such as thermal resistance). The resistance of this current path is called the internal resistance of the MOS tube, that is, the on-resistance. The smaller the internal resistance, the larger the current (because the heat is small).

In simple terms, the motor is driven by the output current of the MOS tube such as NCE80H12. The larger the output current (in order to prevent overcurrent from burning the MOS tube, the controller has limited current protection), the motor torque is strong and the acceleration is powerful, so MOS Tubes play a very important role in electric vehicle controllers.

After the war, Zandman immigrated to France, earning degrees in Mechanical Engineering, Applied Mechanics and General Physics, and a Ph.D. in Mechanical Physics at the Sorbonne University in Paris. It can be said that what Zandman learned during those darker days laid the groundwork for him to start Vishay. For 17 months without the light of day, Zandman's uncle taught him algebra, trigonometry, geometry and physics. . Zandman was born in Poland in 1928. During the Nazi Holocaust in World War II, Zandman was taken in by an old housekeeper whom Zandman's grandmother had rescued. He and four others hid under the housekeeper's floor for 17 months before they were able to escape the Holocaust. . In 1956, Zandman immigrated to the United States and founded Vishay in 1962.

Felix Zandman wrote in his memoir, "Many people think the name sounds odd, but for me, every time I hear it, I think of my grandmother and the power she gave me and others. , think of those Jewish communities in Eastern Europe that were forever erased. Why did Felix Zandman name his company Vishay? Because his grandmother was born in Vishay, the name of a small Lithuanian village in honor of family members killed in the Holocaust ." .

The transfer characteristic refers to the relationship curve between the gate voltage UGS and the corresponding drain current ID when the voltage UDS between the drain and the source is at a certain fixed value. Figure 3 shows the handling characteristics of a certain FET. . The characteristics of a MOSFET can be characterized by a transfer characteristic curve and a drain output characteristic curve.

On the one hand, the three electrodes of the low-power MOSFET are on one plane, the channel cannot be made very short, and the channel resistance is large. The structure of the MOSFET shown in the figure is not suitable for use in high-power applications for two reasons. On the other hand, the conductive channel is composed of surface induced charges, and the channel current is the surface current. To increase the current capacity, it is necessary to increase the chip area. Such a structure is unlikely to achieve a large current. .

The performance parameters of NCE3401 are still good, suitable for load switching or pulse width modulation applications, and the impedance value is relatively low, and the new clean energy MOS tube has the characteristic process technology of shielded gate power and super junction power MOSFET. The parameter performance and sample delivery performance can be almost the same as foreign MOS tubes, such as the same used in lithium battery protection boards, NCE3401, AO3401, IRLML5203TR, DMP3098L-7, I think the functions can be satisfied in comparison, and the price is moderate NCE3401 is more suitable.

The functions of the MOS tube in the protection board are: 1. Detect overcharge, 2. Detect over-discharge, 3. Detect over-current during charging, 4. Detect over-current during discharge, 5. Detect over-current during short circuit.
