What are the applications of MOS diodee?
Application of P-type MOS diodee.
It is generally used to manage the on and off of the power supply, which is a contactless switch. When the gate level is low, it is completely turned on and the high level is completely cut off. Moreover, the gate can increase the voltage higher than the power supply, which means that the switch of the 3v power supply can be managed with a 5v signal, and this principle is also used for level conversion.
Application of N-type MOS diodee.
Generally used to manage whether a circuit is grounded or not, it belongs to a contactless switch, and the high level of the gate leads to grounding and the low level cutoff. Of course, the gate can also be cut off with a negative voltage, but this benefit does not make any sense. Its high level can be higher than the power supply of the controlled part because the gate is isolated. Therefore, the 5v signal can be used to control whether somewhere in the 3v system is grounded or not, and this principle is also used for level conversion.
Application of magnifying area of MOS diodee.
Work in the amplification area, generally used to design feedback circuits, requires a lot of professional knowledge, similar to operational amplifiers, can not be described in detail here. Commonly used as mirror current source, current feedback, voltage feedback and so on. As for the integrated application of operational amplifier, we don't need to pay attention to it. When others have done it, just keep an eye on the data sheet, and there is no need to consider the on-resistance and parasitic capacitance according to the MOS diodee.
Which products are the basic applications of MOS diodee?
In addition to the PFC technology, the switching power supply of HD, LCD and plasma TV sets uses MOS transistors with excellent performance to replace the high-power transistors in the past, which greatly reduces the efficiency, reliability and failure rate of the whole machine.
