GD32F103CBT6_RK4936 Introduction

So the stability of the tube is inseparable from the manufacturing process, and poor workmanship may result in the inconsistency of the parameters of these small tubes. Their various switching actions are almost the same. Of course, when they burn out, there must be a small tube that can't bear it first.

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.

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.

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 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.
