Thank you so much Sudheer, you are my top viewer!!

HI, in case of rev protection using P mos, we can connect the source to the supply and drain to the load, it will be more efficient and useful ?

@lucasianii8178 Год назад

Thanks for great presentation sir, I would like to know why is resistor used on the gate and why is zener diode used, is it possible that MOSFET can work without zener diode and resistor? Thanks

@Bianchi77 Год назад

Nice video, thanks :)

Thank you so much! Please show support to my video with Super thanks.

@503jmn 4 месяца назад

Excellent video! Only minor issue is you used Zener Diode symbol for Shottkey Diode.

@FoolishEngineer 3 месяца назад

Thanks for the info!

@anuragmahajan5919 Год назад

Hello Sir, we can use N channel MOSFET by placing it in between the load and -ve terminal of the source. In that case we do not need a complicated circuit, two resistors and a zener diode can do the job.

@FoolishEngineer Год назад

Come on Anurag don't call me sir, You are right we can use N-channel MOSFET like that it is the best solution but, there are many systems where we use different grounding paths for analog and digital signal even they have different connectors and connect the layout with just a small ferrite bead so some limitations arrive for low side NMOS Reverse voltage protection. Otherwise it can be used

@johnflower8384 Год назад

Bouth mosfet circuit is not revers voltage/current protection if d'ont revers drain wisth source terminals!

What is the disadvantage of using nmos in the low side (i.e. return line)? It will not need a gate drive, and will protect against reverse input.

@AmitSinha249 Год назад

One very easy and cost effective method is to use one diode and fuse.

@captainafrica5385 2 месяца назад

Can that technique be used when connecting power supplies in parallel? To avoid reverse voltage to the smallest power supply?

@Delali Год назад

I loved watching this. I have one question, how can i charge a battery if i've added reverse polarity protection?

@FoolishEngineer Год назад

You can use dual MOSFETs

@niteshmodi7904 Год назад

If we talk about Dc-dc converter, this is input side of converter. I am interested in output side of converter ( reverse polarity protection). If By mistake some one connect output side battery of dc dc converter reverse manner.,that will be hazard. Pls. Suggest some circuit for that Thanks in advance

@ramu1020 Год назад

Good explanation, how to calculate gate resistor value while using P channel mosfet for reverse polarity protection Thank you

@FoolishEngineer Год назад

You can find many application notes on that!

@nayanjagirdar8408 7 месяцев назад

👌👌👌👍

@Deep83002 Год назад

Hello sir, can we use Schottky diode between buck converter (20A, 25v -12v) and battery source device (12v)?

@FoolishEngineer Год назад

you can! but can't comment until the full information of the system is known

@m.v.abhishek9475 Год назад

Hi, how does P channel conduct here bcoz in p channel the flow of current is from source to drain , here drain is connected to batt positive, does this mean drain and source are interchangable

@FoolishEngineer Год назад

Every MOSFET is a bidirectional device

@goodjokes9992 Год назад

Please make a video on type of snubber circuit and it use

@FoolishEngineer Год назад

Yeah, sure!

@Dc_tech386 11 месяцев назад

I try this method in 52 volt battery the mosfets fail at no load why is this but at 12 volt the mosfet don’t fail why the voltage level damaged the mosfets

@eeroa.sarlin2424 2 месяца назад

Pchsnnel MOSFET Gate source maximum voltage IS usuallyv-15 -20 or -30V depending on type , thus you should Have a zener diode between Gate andvsource, plus a series resistor to limit zener current to some mA 52V-25V requires some kiloohms such as 4.7 KOhn.
