BYS3312_SI4854DY-T1-E3 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.

The above is the specification of the power mos tube NCE80H12. The power mos tube NCE80H12 used in our electric vehicle controller is actually different from the low-power mos structure in the usual cmos integrated circuit.

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);

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.

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. .

The main functions of the lithium battery protection board are: 1 overcharge protection, 2 short circuit protection, 3 over current protection, 4 over discharge protection, 5 normal state.

The lithium battery is mainly composed of two blocks, the battery cell and the lithium battery protection board PCM.
