NCE4558K_NCEP6090GU Introduction

In response to this demand, Xinjie can produce N-channel trench process MOS transistors with small internal resistance and good overcurrent resistance - NCE80H12, the on-resistance of NCE80H12 is less than 6mΩ, the output current can reach 120A, and the motor torque is better , .

A few days ago, Vishay Intertechnology, Inc. announced that it has expanded its TNPU e3 series of automotive-grade high-precision thin-film flat chip resistors with new devices with a temperature coefficient (TCR) as low as 2 ppm/K, in 0603, 0805 and 1206 form factors.

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 ." .

. Today the physics book written by Dr. Felix Zandman is used as a basic textbook in many universities, and his autobiography has been translated into Chinese and many other languages. Felix Zandman experienced the Holocaust, lost loved ones, and lived in the dark underground for 17 months in the haze of death. The component industry and even the history of technological development have left a strong legacy. In 2004 Fortune Magazine selected Vishay as one of America's more admired companies.

Barrier capacitance: In power semiconductors, when the N-type and P-type semiconductors are combined, the electrons of the N-type semiconductor will partially diffuse into the holes of the P-type semiconductor due to the concentration difference, so they will form on both sides of the junction surface. Space charge area (the electric field formed by the space charge area will resist the diffusion movement, and finally make the diffusion movement reach equilibrium);

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. 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 structure of the MOSFET shown in the figure is not suitable for use in high-power applications for two reasons.

When the applied forward voltage increases, the concentration of unbalanced minority carriers increases and the concentration gradient also increases, and when the applied voltage decreases, the change is opposite. Diffusion capacitance: When a forward voltage is applied, the non-equilibrium minority carrier concentration near the interface of the depletion layer is high, far from the non-equilibrium minority carrier concentration is low, and the concentration gradually decays from high to 0 until it reaches zero. The process of charge accumulation and release in this phenomenon is the same as that of capacitor charging and discharging, which is called diffusion capacitance.

The main functions of the lithium battery protection board are: 1 overcharge protection, 2 short circuit protection, 3 over current protection, 4 over discharge protection, 5 normal state.

The battery cell is equivalent to the heart of the lithium battery, and the lithium battery protection board is mainly composed of a protection chip (or management chip), a MOS tube, a resistor, a capacitor, and a PCB board.
