BYP3109_ZXMN3A06DN8TC Introduction

When naming the company, the founders incorporated their nostalgia for the past and expectations for the future. A simple name with many untold stories behind it... . There are many well-known brands in the electronics industry, each brand is like a person's name, and its origin and naming have its own unique style. Their success today is due to the founders.

The power mos used on electric vehicles is a three-dimensional structure. The mos tube we have seen is actually composed of thousands of small mos tubes in parallel. You may think that one or a few bad moss should easily appear in thousands of small mos. In fact, it is not that easy. , the current manufacturing process basically guarantees the high consistency of various parameters of these small units. Low-power mos is a planar structure.

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.

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. . The following describes the principle of the MOS transistor with the structure of an N-channel enhancement type low-power MOSFET. Working principle of power MOS tube Power MOS tube is developed from low-power MOS tube.

The N-channel enhancement mode MOS transistor uses a low-doped P-type semiconductor as the substrate, and forms two heavily doped N+ regions on the substrate by a dispersed method, and then generates a very thin one on the P-type semiconductor. A silicon dioxide insulating layer, and then photolithography is used to etch away the silicon dioxide layer on the upper end of the two heavily doped N+ regions, exposing the N+ regions, and finally on the outer surface of the two N+ regions and the two between them. The surface of silicon oxide is sprayed with a layer of metal film by evaporation or sputtering. These three metal films constitute the three electrodes of the MOS tube, which are called source (S), gate (G) and drain (D) respectively. .

For example, electronic fuel injection system, anti-lock brake control, anti-skid control, traction control, electronically controlled suspension, electronically controlled automatic transmission, electronic power steering, etc. The electronic device that can be used independently in the environment has no direct relationship with the performance of the car itself. .
