BYM31545_DMN3018SSD Introduction

In simple terms, the motor is driven by the output current of the MOS tube such as NCE80H12. The larger the output current (in order to prevent overcurrent from burning the MOS tube, the controller has limited current protection), the motor torque is strong and the acceleration is powerful, so MOS Tubes play a very important role in electric vehicle controllers.

The resistance of this current path is called the internal resistance of the MOS tube, that is, the on-resistance. 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 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. .

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. .
