BYP31017_AP4226GM Introduction

A few days ago, Vishay Intertechnology, Inc. announced that it has expanded its TNPU e3 series of automotive-grade high-precision thin-film flat chip resistors with new devices with a temperature coefficient (TCR) as low as 2 ppm/K, in 0603, 0805 and 1206 form factors.

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.

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.

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 . Figure four types of MOSFETs and their graphical symbols.

When the UDS increases to a certain value, the drain PN junction breaks down, the leakage current increases rapidly, and the curve turns upward and enters the breakdown region. Power MOSFETs are used in power conversions such as switching power supplies and inverters, and they work in two regions, the cut-off region and the breakdown region. . The full area (UDS>UGS-UT) guarded in the above three areas is the full area, also known as the constant current area or the amplification area. The breakdown region is in the region of considerable drain-source voltage UDS, and the drain current is approximately constant.

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. .
