As people pay more and attention to the quality of the air, air purifiers have become standard equipment for families and workplaces. It integrates multi-domain technologies, and the common types are pure physical filtration type relies on HEPA filter to intercept dust ...
When the circuit is powered on, due to the voltage division of R97 and R99, the base voltage of Q63 is pulled, and it is in the cut-off state. At this time, the gate voltage of the MOS transistor Q62 is close to the source voltage ( 2V), and since the gate-source voltag...
In circuit design, both diodes andFETs can be used for anti-reverse connection. However, diodes have the issues of voltage drop and power consumption, making them only suitable for low-current low-power scenarios. Therefore, in most cases, we will use a MOSFET anti-reve...
Take an NMOS switch circuit as an example, where step signal VG1 sets the DC level to 2V and is a square wave with an amplitude of 2V and a frequency of 50Hz and the turn-on voltage of T2 is also 2V, which causes the MOSFET T2 to switch between the on and off states wit...
How to use the characteristics to design anti-reverse connection circuits?
In electronic circuits, MOSFETs are commonly used as power switching elements, the design of their gate drive circuits significantly affects performance. Today, we will introduce three common MOSFET gate drive circuits.
