Comparing the equality of the original type is different from comparing two objects. If the value 5 is stored in two different int variables, comparing whether the two variables are equal will result in a Boolean value true:

enhanced P-Channel MOS tube (e.g. SI2333DS) switching conditions
when used as a switch, the PMOs tube is controlled by the VGS voltage value to control the continuity between S (source) and D (drain drain).
the minimum threshold voltage for the VGS is 0.4v, which means that the source and drain electrodes are on when the S (source) voltage-G (Gate gate) Pole > 0.4V.
and VS = Vd, the S-pole voltage is equal to the D-pole voltage.
For example:

When using MOS to design a switching power supply or motor drive circuit, most people will consider the mos on-resistance, maximum voltage, maximum current, and so on. Many people only consider these factors. Such a circuit may work, but it is not excellent. It is not allowed as a formal product design.
The following is my summary of the basis of the mos and MOS driving circuit. I have referred to some materials, not all or

The macro-synthesis of micro-elements such as their potentials, interests, abilities, aspirations, perseverance, diligence and self-confidence is of vital importance in the education of mathematical talents.

inductance and lead inductance of the power supply pin and ground pin is LV and LG respectively. Two complementary MOS tubes (ground NMOS and PMOS connected to power supply) are used as switches. Assuming that the voltage and current at each point on the transmission line are zero at the initial time, the device will drive the transmission line to a high level at a certain time point, then the device will need to absorb the current from the power sup
