GD32F205RGT6_STS2DNF30L Introduction

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.

The size of this internal resistance basically determines how much on-current the MOS tube chip can withstand (of course, it is related to other factors, such as thermal resistance). The smaller the internal resistance, the larger the current (because the heat is small). The resistance of this current path is called the internal resistance of the MOS tube, that is, the on-resistance.

Figure four types of MOSFETs and their graphical symbols. Power MOSFETs are generally rarely used in P-channel. Since the mobility of holes is lower than that of electrons, the on-resistance of P-channel transistors is larger than that of N-channel transistors for the same channel size. . According to the two points of the conductive channel and the process of channel formation, MOS tubes can be divided into: P-channel enhancement MOS tubes, P-channel depletion MOS tubes, N-channel enhancement MOS tubes and N-channel depletion MOS tubes .

The conductive channel of the MOS tube can be formed during the production process or by turning on an external power supply. When the gate voltage is equal to zero, there is a channel (that is, formed during production), which is called depletion mode. When an external voltage is applied The one that forms the channel later is called the enhancement type. .
