Dec 4, 2017 · This is the datasheet of the driver IC I am working on (LM5112). Following is the application diagram of the module. Basically this is the GATE driver circuit for the MOSFET with PDM signal as the input. I am looking for how to calculate value of the MOSFET input resistor (R3) ? MOSFET input voltage (VDS) = 10V Output power required is 200W ...
mosfet - High side driver and Low side driver - Electrical …
Sep 3, 2015 · Can anybody help me understand, what exactly a high side and low side driver is? In which scenario would either of them be used?
transistors - Understanding the curves of a MOSFET - Electrical ...
Mar 10, 2021 · I am trying to understand the curves of a MOSFET. Sorry if the question is very basic. Where the red point is is the saturation zone of the MOSFET, therefore the source drain voltage must be 0V bec...
What is the difference between MOSFET transistor and normal …
Jan 19, 2019 · [From Question]: MOSFET transistor and normal transistor A MOSFET is a normal transistor - it's a Metal-Oxide-Semiconductor Field-Effect Transistor A BJT is another normal transistor - a Bipolar Junction Transistor The question itself doesn't make much sense in that regard. But lets assume for now you mean BJT when you say "normal".
mosfet - Is reverse polarity protection this simple? - Electrical ...
Jun 10, 2022 · Note that reverse polarity (reverse voltage at the inputs driving current backwards) is different than load dumping (the load producing a voltage higher than the input driving current backwards). A diode protects from both, this does not.
Calculation of MOSFET gate drive current
Jun 4, 2020 · I know that there have been many posts on this topic, but I'm confused about calculating the gate current of a MOSFET. I have calculated the gate current as Igs = Qg/t. For example, I want to drive

mosfet - Is there an equation to calculate the voltage spike caused …
Apr 10, 2024 · I am using a MOSFET as a low side switch. If I do not use a freewheeling diode to discharge the energy stored in the inductor, what is the numerical value of the spike cause at the intersection node of the inductor and the drain of the low side N-channel MOSFET when it is turned off? Is there an equation describing this? Diagram given below.
mosfet - Working of NMOS as a capacitor - Electrical Engineering …
Feb 1, 2019 · If drain/source is connected to VDD, its as good as open (0 capacitance) , you get capacitance but not zero. How to reason out the need for large length and small width? Also a wrong assumption, size of MOSFET will work as a capacitor. The series resistance of the capacitor is generally smaller (you get a "better" capacitor) when the width is large and length …
