NCE0115K_NCEP01T13 Introduction

Xinjie, behind this FET NCE80H12, utilizes its own technical advantages to work closely with 8-inch wafer foundries, packaging and testing foundries, and has a complete quality management system to ensure continuous product quality and stable supply.

The power mos used on electric vehicles is a three-dimensional structure. Low-power mos is a planar structure. The mos tube we have seen is actually composed of thousands of small mos tubes in parallel. You may think that one or a few bad moss should easily appear in thousands of small mos. In fact, it is not that easy. , the current manufacturing process basically guarantees the high consistency of various parameters of these small units.

. For these two enhanced MOS tubes, NMOS is more commonly used. As for why not to use depletion-type MOS tubes, it is not recommended to get to the bottom of it.

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. .

Barrier capacitance: In power semiconductors, when the N-type and P-type semiconductors are combined, the electrons of the N-type semiconductor will partially diffuse into the holes of the P-type semiconductor due to the concentration difference, so they will form on both sides of the junction surface. Space charge area (the electric field formed by the space charge area will resist the diffusion movement, and finally make the diffusion movement reach equilibrium);

MOSFET is a type of FET (the other is JFET), which can be made into enhancement mode or depletion mode, P-channel or N-channel, a total of 4 types, but only the enhancement-mode N-channel MOS is actually used. Tube model and enhanced P-channel MOS tube model, so NMOS is usually mentioned, or PMOS refers to these two.

. 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.

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 breakdown region is in the region of considerable drain-source voltage UDS, and the drain current is approximately constant. . 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. 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 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.
