mosfet

Hello All, For example, this gate driver from Ti (UCC21520) can drive GaNFET, IGBT, and MOSFET. But can it drive SiC MOSFET? Or maybe the IGBT Gate Driver (NCV57000) from onsemi, can it drive Si/SiC MOSFETs? why not a generic gate driver that can drive all switching devices? Thank you,

There're many articles and videos in the internet saying that FinFET has a big advantage in transistor density, however it's difficult for me to find an example about how one FinFET's fins are actually connected to other electrodes such that the density is increased compared to using MOSFET. I...

Dear All About Circuits Team, I hope everyone is doing well, I have a question about the MOSFET's behaviour, How can I figure out how much heat the Mosfet produces per amp and how much current it can consume when acting as a load? Below, the Mosfet application shown in the figure, it's an...

Is this circuit okay to drive dc motors with atmega? While sending to one signal input other one will be grounded from microcontroller. If not okay what additions or substractions are needed to create ideal h-bridge for dc motors to drive with atmega?

I was recently asked to use 2 mosfets to make a switch that turns a fan on/off via a PWM pin of an stm32 (this allows a gradual switch-on of the fan and not all at once .. here). I cannot understand why I need two and not one mosfet. Maybe it's because having a GPIO PWM [0 ... 3.3]V output that...

I need clarification regarding ROHS compatibility of NVTFS5C471NLWFTAG(n-Channel MOSFET). Document given by onsemi says Now, I need to confirm this ROHS compliant or not? Because the exception calls for “Lead in high melting temperature type solders(i.e. lead based solder alloys...

When RLC is in a resonance state that means the total impedance seen by Vs is just Rs. I see no use in this information. This problem kinda confuses me because there's no current flowing into the gate of this transistor so there would be no voltage drop in Rs so the amplitude at the gate would...

Here is the circuit: Here is the solution (taken from the book RF microelectronics by Behzad Razavi): My attempt: First i tried to find the gain expression for this circuit, i noticed that M2 is in diode configuration so in the small signal model M2 is equivalent to a resistor (=...

I am trying to use a monostable 555 timer circuit to control a peristaltic pump. But, the timer duration is not consistent. I replaced the fet and motor with LEDs and the timer behaves as expected (on for ~10s with the pot at 1 Mohm). What else do I need to have the timer drive the fet properly...

Dear all, can anyone share TL072 op-amp LT Spice Model with me (probably better if placed in zip file ) ? I am trying to simulate a TL072 to produce 1MegaHertz sine wave :) Thank you for your help :)

Below is Triangular Modulation Output of a Triangle input wave HI all, I have been trying to understand modulation and demodulation circuitry as part of my hobby :) The modulation circuit above works fine but when I connect the output of the modulator to the demodulator (as shown by blue...

I am wondering if it would be possible to swap out the MOSFETs on the picoUPS-100 by Mini-Box for higher-powered ICs. I know it would void the warranty, but it would be great to get a little more juice out of the device...

Referring to website link at here , this circuit tries to replicate the waveform of input voltage and make it to a high frequency, I try to simulate the circuit in LT Spice but the output is weird. May I know the solution to this? Below is my attached LT Spice for your convenience. Thank you...

Both of this graph show mosfet and but in switching mode As i look at the graph below I notice for mosfet the drain source amplitude is higher than the gate voltage amplitude . However , bjt , collector voltage amplitude is only reach at the same amplitude of base voltage amplitude. From this...

I'm looking to use an optocoupler+MOSFET to switch "undefined" DC power sources; the opto I'm looking at is FOD817D and the MOSFET is FDPF55N06. The power sources may range from 5V (USB power) to 24V, but I could see this being used to switch as high as 36V at some point in the future, and...

Dear all, I am looking for a circuit that can on an led by pressing the same button for 3 times? Thank you for reading and have a nice day:)

Hi all, I'm trying to drive a RFP30N06LE N-Channel MOSFET with TC4420 MOSFET Driver. The MOSFET is used to switch a [1W LED][1]. The input to the MOSFET driver is provided by the 5V from an Arduino Nano. But my circuit is not working: it seems that the VDD somehow leaks to the input of the...

Hello Hello I am using a MOSFET driver circuit with SI2303 as p-channel mosfet and SI2302 as n-channel mosfet. I have given control signal (of 5V) on the gate of n-channel mosfet to turn-on and off the p-channel mosfet. However, the p-channel mosfet is not getting off and I am constantly...

I'm working on a remote start system for an older gm diesel vehicle and so far everything has worked great, but I've hit a stump that I just cant figure out. The engineers who designed the ignition switch of my truck though it would be a good idea to run starter solenoid power though the...

Hello, I have a question regarding operational amplifiers. Whenever I search for some datasheets of high gain and high-speed Op Amps ( BW higher than 50MHz), I mostly find that they are made of bipolar transistors rather than mosfet. Why is it so? I've done some research and I've found that...
