Push Pull MOSFET Gate Driver | Totem Pole MOSFET | ltspice simulation

#PushPullMOSFET #TotemPoleMOSFET #gatedriver #ltspice #simulation
This video explains design and ltspice simulation of Totem Pole MOSFET Gate Driver. It is sometimes also called Push-Pull MOSFET Gate Driver.
This circuit is cost effective solution for gate driving.
Don'n be confused between totem pole mosfet gate driver and push pull mosfet gate driver. They both are same.
Be careful in MOSFET selection.

Really great video❣️❣️❣️

[@ElectronicsCircuitHubECH]

Thanks for your compliment.

[@darvinr9074]

Pls need more videos like this and also explain and simulation about common mode choke

[@ElectronicsCircuitHubECH]

@@darvinr9074 Thanks for your input. I will try to explain about common mode choke. You can find common mode choke calculation video on this channel.

I don’t use a npn transistor to amplifier my signal voltage so the base voltage is from the pwm pulse 15volt and my totem pole driver use 55 volt and the gate voltage was always 15volt to the mosfets the circuit work great if the mosfet was getting 55 volt the mosfet would damage so there is 3 type of totem voltage is one and current is over and both

[@ElectronicsCircuitHubECH]

Thanks for your feedback.

[@LaboussoleNano]

Thanks for your video, I have a question if you want the driver to switch bipolar (+10V to -5V) how do you do? I your example it just switching 12V and 0V

[@ElectronicsCircuitHubECH]

Hey...can you connect me on whatsapp no. given in channel homepage.

[@LaboussoleNano]

@@ElectronicsCircuitHubECH ok thanks

What change would you make to the circuit if you were using 3.3V logic signal that has to keep it on at 3.3V

[@ElectronicsCircuitHubECH]

Hi..I did not understand your question. Could you please elaborate more ?

[@mayoortechinnovations]

Nice video.. please what is the work of R4 (12k) in the circuit and what will be the effect if i reduce it to 1k .... thanks

[@ElectronicsCircuitHubECH]

Hey...thanks for asking good question...R4=12K so IR4 = 12V/12K = 1mA. Portion of 1mA will be flowing through collector and base of the transistors. In case of 12mA (12V/1mA) may damage base of transistor.

[@BinuThomas-mj1go]

Nice..can you sent a circuit using mosfet flasher on time less off time more like 5seconds

[@ElectronicsCircuitHubECH]

Please contact me on whatsapp [phone]

[@user-gr4il6co4y]

what are the differences between totem pole and push pull?

[@ElectronicsCircuitHubECH]

Hi....more or less both are same.

[@EmreninLaboratuvari]

Hello, first of all Thank you for the video. I have a question for about the pulse voltage supply current wich is -3.2 mA in some cases. Could this negative current burn or damage the mcu in real world ?

[@ElectronicsCircuitHubECH]

Hey...thanks for asking very good question. You can increase the base resistance of npn transistor anywhere between 3.3K to 4.7K to reduce the base current. Now coming back to your original question, if you configure micro pin as push pull configuration then only it will source and sink the current . incase of output high and low it will only source. Incase case sinking 3.3mA of current from MCU pin is not going to damage the MCU. Micro controller can source/sink 8-10mA current form mcu pin unless and untill the summation of all pin current will remain within the limit. This also depends on manufacturer to manufacturer (mcu to mcu). For example if summation of all pin current is 40mA so you can draw 8mA from any 5 mcu pin .

[@ElectronicsCircuitHubECH]

Look at any mcu datasheet for better understanding. Hope this help. Its hard to explain everything here in comment.

[@EmreninLaboratuvari]

​@@ElectronicsCircuitHubECH I never thought of this. I understand now, thank you for your detailed explanation.

[@ElectronicsCircuitHubECH]

@@EmreninLaboratuvari Good Luck, Keep Learning!
