GD32F350C6T6_AO4840&Special 30V Guide

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.

Today I will introduce to you a domestic FET that is suitable for lithium battery protection boards and can replace MOS tubes such as AO3401: NCE3401.

However, in terms of structure, there is a big difference between them. In order to better understand the mechanism of power MOSFET, we must first recall the mechanism of low-power FET. . Working principle of power MOS tube Power MOS tube is developed from low-power MOS tube. The following describes the principle of the MOS transistor with the structure of an N-channel enhancement type low-power MOSFET.

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);

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