AP9926EM_4946BW Introduction

Assuming that the carriers of the conductive channel are electrons, it is called an N-channel; assuming that the carriers are holes, it is called a P-channel. According to the carrier of the conduction channel, it can be divided into N channel and P channel. A MOS tube is a semiconductor device in which unipolar carriers participate in conduction.

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 reason is that the on-resistance is small and it is easy to manufacture. Therefore, in the application of switching power supply and motor drive, NMOS is generally used.

The parasitic capacitance structure of the MOS tube is as follows. Among them, the width of polysilicon, the width of the channel and the trench, the thickness of the G oxide layer, and the doping profile of the PN junction are all factors that affect the parasitic capacitance. .

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