NCE3400E_NCEP30T12G Introduction

The above is the specification of the power mos tube NCE80H12. The power mos tube NCE80H12 used in our electric vehicle controller is actually different from the low-power mos structure in the usual cmos integrated circuit.

The MOS tube is a voltage-driven device. As long as an appropriate voltage is applied between the gate G and the source S, the conduction path between the source S and D will be formed. As the switch tube of the driving part, the main focus of the MOS tube is the withstand voltage, current withstand value and switching speed.

. As for why not to use depletion-type MOS tubes, it is not recommended to get to the bottom of it. For these two enhanced MOS tubes, NMOS is more commonly used.

The company's founder, Felix Zandman, is a scientist, inventor and entrepreneur with 71 patents, author of four books and many papers, winner of the American Electronics Industry Medal of Honor, the French Medal of Honor and many other awards. Founded by Dr. Felix Zandman in 1962, Vishay has grown into a Fortune 1000 company listed on the New York Stock Exchange from his own $4,000 savings and funding from his cousin Alfred P. Slaner. .

There is parasitic capacitance between the three pins of the MOS tube, which is not what we need, but is caused by the limitation of the manufacturing process.

These two factors make Vishay's MELF resistors the choice for high-end audio applications with low noise requirements. Vishay's MELF resistors are produced using an advanced vacuum sputtering process that deposits a layer of a proprietary nickel-chromium alloy of extremely high microstructural quality on a very smooth aluminum substrate in an ultra-high vacuum chamber. This sophisticated internal structure provides the ideal foundation for low-noise performance, which is further enhanced by the cylindrical shape of the resistor. With a 3.14 times larger surface area than flat chip resistors for the same pad size, these devices can produce much higher aspect ratios, resulting in very low field strengths along the resistors. Be aware that the local electric field strength is the main source of current noise. Compared to thick film resistors, this typically provides a spectral density improvement of about -40 dB V/Hz, a figure of about -10 dB V/Hz in the case of thin film resistors, as shown in Figure 2.

In the lithium battery protection board, the most important thing is to protect the chip and MOS tube.

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.
